1. Distribute the 10: 30p + 40
If you are solving for p, then subtract 40: 30p = -40
Then divide 30: p = -40/30, simplified to p = -4/3
Answer:
30p -40
Step-by-step explanation:
You want to simplify the expression -10(-3p +4).
Distributive propertyThe distributive property tells you the product is ...
-10(-3p +4)
= (-10)(-3p) + (-10)(4)
= 30p +(-40)
= 30p -40
__
Additional comment
It is easy to get confused by minus signs. For any given numerical product the sign of the result will be negative if (and only if) the number of negative factors is odd.
Here, the first product is (-10)(-3p), which has an even number of minus signs. The result will be the same as with no minus signs:
(-10)(-3p) = (10)(3p) = 30p
On the other hand, the product (-10)(4) has an odd number of minus signs. That result will be negative:
(-10)(4) = -40
For this problem, you could start by distributing the minus sign, changing the sign of each term inside the parentheses:
-10(-3p +4) = 10(3p -4)
Doing this can simplify the mental load of figuring the signs of the product terms.

How long would it take the bowling ball to fall 150 feet? (Estimate your answer to one
decimal place. Hint: Use the equation d = 16t².)
It would take the bowling ball approximately 3.1 seconds to fall 150 feet.
What is distance?
Distance is the total movement of an object, regardless of direction. We can define distance as how much ground an object has covered, regardless of its starting or ending point.
Distance is defined as the size or amount of displacement between two positions. Note that the distance between two locations is not the same as the distance between them. The distance traveled is the total length of the path traveled between two positions.
Here given equation,
d = 16t², where t is the time in seconds and d is the distance in feet and distance is 150 feet.
We want to find the value of t.
Now,
[tex]d = 16 {t}^{2} \\ {t}^{2} = \frac{d}{16} \\ {t}^{2} = \frac{150}{16} \\ t = \sqrt{( \frac{150}{16}) } \\ t = \sqrt{9.375} \\ t = 3.0619[/tex]
So, t = 3.1 (rounded to one decimal place)
Therefore, it would take the bowling ball approximately 3.1 seconds to fall 150 feet.

B. Only function f is increasing, and only function f is negative.
C. Both functions are increasing, but function f increases at a faster average rate.
D. Only function f is increasing, but both functions are negative.
The statement that correctly compares the two functions on the interval [-1, 2] is A. Both functions are increasing, but function g increases at a faster average rate.
How to explain the functionFor function f, as x increases from -2 to 2, we can see that the corresponding values of f(x) also increase, but at a decreasing rate. This is because the function is exponential and approaching a horizontal asymptote as x goes to infinity. Therefore, f(x) is increasing, but at a decreasing rate.
For function g, we don't have enough information to determine if it's increasing or not, since only its equation is given. The correct option is A.

The nth term of the sequence 3/2, 3, 7, 16, 35, 74,... is?
Answer:
95 is the sequence
Step-by-step explanation:
The given sequence appears to follow the pattern where each term is obtained by multiplying the previous term by 2 and then adding 1. Using this pattern, we can derive a formula for the nth term of the sequence as a(n) = 3 * 2^(n-1) - 1, where a(n) represents the nth term of the sequence and n is a positive integer.
For example, to find the 6th term of the sequence, we can substitute n = 6 into the formula to get a(6) = 3 * 2^(6-1) - 1 = 3 * 2^5 - 1 = 95. So, the 6th term of the sequence is 95.
Entre que valores varía la masa corporal MC de la mayoría de estudiantes?
The majority of students have a body mass between 46.7 and 79.1 kg, and there are 36 students with a body mass of 61.7 kg or greater.
Assuming a normal distribution of body mass among the students, we can use the concept of standard deviation to answer the question. Let's assume that the mean body mass of the students is 60 kg, and the standard deviation is 5 kg.
To find the range of body mass where the majority of students fall, we can use the empirical rule, which states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations.
Therefore, the range of body mass where the majority of students fall is between 55 kg (60 kg - 5 kg) and 65 kg (60 kg + 5 kg).
To find the number of students with a body mass equal to or greater than 61.7 kg, we need to find the z-score of 61.7 kg, which is
(61.7 - 60) / 5 = 0.34.
We can then use a standard normal distribution table to find the proportion of the area to the right of this z-score, which is 0.3665. This means that approximately 36.65% of the students have a body mass equal to or greater than 61.7 kg.

The diameters of cherry tomatoes produced by a large farm have an approximately Normal distribution, with a
mean diameter of 22 mm and a standard deviation of 2. 5 mm. After they are picked and washed, tomatoes with a
diameter of at most 15 mm or at least 30 mm are rejected and not sold. What proportion of such tomatoes are
rejected?
Find the z-table here.
O 0. 0033
O 0. 0201
O 0. 9799
O 0. 9967
The proportion of cherry tomatoes that are rejected based on their diameter is 0.0033. (option a).
To use the CDF, we need to standardize the diameter values using the z-score formula:
z = (x - μ) / σ
where z is the z-score, x is the diameter value, μ is the mean diameter, and σ is the standard deviation.
For tomatoes with a diameter of at most 15 mm, we have:
z = (15 - 22) / 2.5 = -2.8
For tomatoes with a diameter of at least 30 mm, we have:
z = (30 - 22) / 2.5 = 3.2
Next, we use the z-table to find the area under the Normal distribution curve that corresponds to these z-scores. For a z-score of -2.8, the area is 0.0026. For a z-score of 3.2, the area is 0.9993.
Finally, we add these two areas together to get the total proportion of rejected tomatoes:
proportion = 0.0026 + (1 - 0.9993) = 0.0033
Hence the correct option is (a).

Whats a product with 2 consecutive digits
The two consecutive digits whose product is 132 are equals to 11 and 12.
Product of two consecutive digits = 132
Let us consider that the two consecutive digits are y and y+1.
Then we can write the expression as,
⇒y × ( y + 1 ) = 132
Expanding the left side of the expression, we get,
⇒ y² + y = 132
Rearranging the values and solving for y, we get,
⇒ y² + y - 132 = 0
Factorize this quadratic equation to get the value of y we have,
⇒ y² + 12y - 11y - 132 = 0
⇒ y( y + 12 ) -11 ( y + 12 ) = 0
⇒ ( y + 12)(y - 11) = 0
This implies,
The two possible values of y are -12 and 11.
However, choose the positive value of y .
Since we are dealing with digits.
Thus, y = 11, and the consecutive digits are 11 and 12.

GIVEN: Circle with center C and point D.
CONSTRUCT: Equilateral triangle DEF so that points E and F are on circle C.
Circle with center C and point D. Triangle CDE and triangle CDF are both equilateral, and we have DE = EF = FD.
What is construction?
In the context of geometry, construction refers to the process of creating geometric figures or shapes using only a compass and straightedge (also called a ruler). The goal of construction is to create accurate and precise geometric figures using only these two tools and a given set of instructions.
To construct an equilateral triangle DEF with points E and F on circle C, we will follow the following steps:
Step 1: Draw a circle with center C and point D on it.
Step 2: Draw a line through points C and D. This line will be the base of our equilateral triangle DEF.
Step 3: Construct the perpendicular bisector of line CD. This can be done by drawing two circles with centers at C and D, both with radius greater than half the length of CD. The two circles will intersect at two points, and the line passing through these two points will be the perpendicular bisector of CD.
Step 4: Let G be the intersection point of the perpendicular bisector and circle C that is closest to point D. Draw lines from G to points C and D. These lines will intersect circle C at points E and F, respectively.
Step 5: Check that the length of CE is equal to the length of CF. This can be done using a compass and ruler.
Step 6: Finally, draw lines from points E and F to point D. The resulting triangle DEF will be equilateral.
To prove that triangle DEF is equilateral, we can show that DE = EF = FD. We already know that CE = CF from step 5. Since C is the center of the circle, CE = CF = CD. By construction, angle ECD and angle FCD are both 60 degrees, since they are inscribed angles that intercept the same arc.
Therefore, triangle CDE and triangle CDF are both equilateral, and we have DE = EF = FD.

A Reflect triangle over the line x = -1 will take ABC to A"B"C".
What is triangle reflection theorem?
The outcome is the same as rotating the initial triangle 180 degrees around the origin, just as the theorem predicts, when we reflect the triangle over the y-axis and then cross the x and y axes while reflecting the outcome across the x axis.
The single transformation that takes ABC to A"B"C" is a reflection over the line x = -1.
The new triangle A'B'C' is formed by reflecting ABC across the line x = -2, where each point in A', B', and C' is the reflection of the corresponding point in ABC. As a result, A', B', and C''s x-coordinates are all 4 units to the left of A', B', and C''s x-coordinates.
The final triangle A"B"C is formed by reflecting A'B'C' over the line x = 0, where each point in A", B", and C" is a reflection of the corresponding point in A'B'C' over the line x = 0. Accordingly, the x-coordinates of A, B, and C" are all located two units to the right of the x-coordinates of A', B', and C'.
If we combine these two reflections into a single transformation, we can think of it as reflecting ABC over a line that is 2 units to the right of x = -2, which means it has an equation of x = -2 + 2 = -1. This line is the perpendicular bisector of the segment connecting the points (-2, 0) and (0, 0), which is the line that connects the two reflection lines x = -2 and x = 0.

3-6 You can determine the slope of a roof using a flat board, a bubble level and a ruler,or a sight card can be used. (True or False)
Given statement "3-6 You can determine the slope of a roof using a flat board, a bubble level and a ruler,or a sight card can be used." is true. Because flat board, a bubble level and a ruler,or a sight card methods are commonly used to determine the slope of a roof, and both are effective.
Determining the slope of a roof is an important task for many construction and roofing projects.
One method to determine the slope of a roof is to use a flat board, a bubble level, and a ruler.
First, place the flat board horizontally on the roof surface, and use the bubble level to make sure it is level.
Then, measure the distance between the bottom of the board and the roof surface at the point where the board intersects with the roof using the ruler. This distance is the rise.
Next, measure the distance from the point where the board intersects with the roof to the end of the board using the ruler. This distance is the run. Finally, divide the rise by the run to get the slope.
Another method to determine the slope of a roof is to use a sight card. A sight card is a specially designed tool that can help to measure the angle of a slope or pitch. The sight card is held at the bottom of the roof and lined up with a known vertical or horizontal line, such as the edge of a building.
Statement is true.

Lucy received a $1300 bonus. She decided to invest it in a 3-year certificate of deposit (CD) with an annual interest rate of 1.27% compounded monthly.
Answer the questions below. Do not round any intermediate computations, and round your final answers to the nearest cent. If necessary, refer to the list of financial formulas.
(a) Assuming no withdrawals are made, how much money is in Lucy's account after 3 years?
$____
(b) How much interest is earned on Lucy's investment after 3 Years?
$____
Answer:
(a) $1350.46
(b) $50.46
Step-by-step explanation:
You want to know the future value of a $1300 CD earning 1.27% compounded monthly for 3 years, along with the amount of interest earned.
Future valueThe compound interest formula tells you the future value is ...
FV = P(1 +r/12)^(12·t)
where r is the annual interest rate and t is the number of years.
ApplicationUsing the given values, we have ...
FV = $1300(1 +0.0127/12)^(12·3) ≈ $1350.46
(a) The value after 3 years is $1350.46.
The interest earned is the difference between the final value and the amount of the original investment:
Interest = $1350.46 - 1300.00 = $50.46
(b) The interest earned by the CD is $50.46.
