Evaluate 3x²-x+7) dx
Answer & Step-by-step explanation:
I assume you mean to differentiate the equation.
We will solve using the power rule, where x^n = nx^n-1.
Apply this rule to all three numbers in our equation to get 6x, -1, and 0
The slope of a line is m= -4.
(a) Determine the slope of a line parallel to the line with the given slope.
(b) Determine the slope of a line perpendicular to the line with the given slope.
Select "Undefined" if applicable.
Part 1 of 2
The slope of a line parallel to the given slope is
Part 2 of 2
The slope of a line perpendicular to the given slope is
Answer:
a) -4
b) 1/4
Step-by-step explanation:
a) -4. This is because parallel lines have the same slope.
b) 1/4. This is because the product of perpendicular slopes will be -1. (This can be seen as -4 * 1/4 = -1)

Garrett's coin bank contains 500 nickels,
dimes, and quarters. He has the same
number of nickels as dimes, and the total
value of the coins is $72.50. How many
quarters does he have?
Step-by-step explanation:
d = number of dimes
n = number of nickels
q = number of quarters
d + n + q = 500
d×$0.10 + n×$0.05 + q×$0.25 = $72.50
n = d
we are focusing now on one variable (let's try d), and we are transforming the other equations to express the other variable by this one variable.
since n = d we have already
d + d + q = 500
2d + q = 500
q = 500 - 2d
with that we go into the main equation
d×0.10 + d×0.05 + (500 - 2d)×0.25 = 72.50
d×0.15 + (500 - 2d)×0.25 = 72.50
d×0.15 + 500×0.25 - 2d×0.25 = 72.50
d×0.15 + 125 - d×0.50 = 72.50
-d×0.35 = -52.50
d = 52.50/0.35 = 150
n = d = 150
q = 500 - 2d = 500 - 2×150 = 500 - 300 = 200
so, he has 200 quarters.

What is the domain of the equation that is graphed?
Step-by-step explanation:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis. Keep in mind that if the graph continues beyond the portion of the graph we can see, the domain and range may be greater than the visible values. See Figure 6.
Figure 6
We can observe that the graph extends horizontally from
\displaystyle -5
−5
to the right without bound, so the domain is [−5,∞). The vertical extent of the graph is all range values 5 and below, so the range is (−∞,5]. Note that the domain and range are always written from smaller to larger values, or from left to right for domain, and from the bottom of the graph to the top of the graph for range

-7/3(12q+1/3r+6) someone help me I need it for something important
Answer:
Below
Step-by-step explanation:
-7/3 ( 12q + 1/3r + 6 )
multiply each number in the parentheses separately by - 7/3
- 7/3 ( 12q) = - 84/3 q or - 28q
- 7/3 ( 1/3r) = - 7/9 r
- 7/3 ( 6) = -42/3 or - 14
Putting back together you get
-28q - 7/9r - 14

Answer:
90+30+2x=180
Step-by-step explanation:
2x is an angle, so we need to find its measure
square symbol at corner of triangle means 90 degrees
we know the angle at the top corner is 30 degrees
the sum of all the angles in a triangle is 180 degrees
so the sum of 90 degrees, 30 degrees, and 2x degrees is 180 degrees
translate it to mathematical format: 90+30+2x=180

Tommy has $350 of his graduation gift money saved at home, and the amount is modeled by the function h(x) = 350. He reads about a bank that has savings accounts that accrue interest according to the function s(x) = (1.04)x−1. Explain how Tommy can combine the two functions to model the total amount of money he will have in his bank account as interest accrues after he deposits his $350. Justify your reasoning.
Answer:
So the functions that are given are the following:
[tex]h(x)=350\\s(x)=(1.04)^{x-1}[/tex]
So in order to find the money in his account, there would have to be a substitution for (x=$350) in the first function, and a place in the second function.

The cost of a cup of tea is t cents.
The cost of a cup of coffee is (t + 5) cents.
The total cost of 7 cups of tea and 11 cups of coffee is 2215 cents.

Find the cost of one cup of tea.
Step-by-step explanation:
The cost of a cup of tea is t cents.
The cost of a cup of coffee is (t + 5) cents.
The total cost of 7 cups of tea and 11 cups of coffee is 2215 cents.
Therefore,
7t+11t+55=2215
18t=2160
t=120
Given the recursive formula shown, what are the first 4 terms of the sequence?
Applying the recursive formula f(n) = f(n-1) + 4 with the initial condition f(1) = 3, we obtain the sequence 3, 7, 11, 15, which corresponds to option D) in the given choices. Optiopn D
To find the values of the sequence defined by the recursive formula f(n) = f(n-1) + 4, with the initial condition f(1) = 3, we can apply the formula repeatedly, starting from n = 2.
Using the given formula, we can calculate the values of the sequence as follows:
f(2) = f(2-1) + 4 = f(1) + 4 = 3 + 4 = 7
f(3) = f(3-1) + 4 = f(2) + 4 = 7 + 4 = 11
f(4) = f(4-1) + 4 = f(3) + 4 = 11 + 4 = 15
The values we obtained are: f(1) = 3, f(2) = 7, f(3) = 11, and f(4) = 15.
Comparing these values to the options provided:
A) 3, 9, 11, 13
B) 3, 8, 10, 12
C) 4, 7, 10, 13
D) 3, 7, 11, 15
We can see that option D) 3, 7, 11, 15 matches the values we calculated using the recursive formula. Therefore, the correct answer is option D).

Answer
Using the probability concept, it is found that there is a 0.6087 = 60.87% probability of a puppy having no spots.
A probability is the number of desired outcomes divided by the number of total outcomes, that is:
[tex]p = \frac{D}{T}[/tex]
In this problem:
There are 6 + 8 + 4 + 5 = 23 puppies, thus [tex]T = 23[/tex].6 +8 = 14 have no spots, thus [tex]D = 14[/tex]Then, the probability is:
[tex]p = \frac{D}{T} = \frac{14}{23} = 0.6087[/tex]
0.6087 = 60.87% probability of a puppy having no spots.

Which pair of numbers are not opposites?
|7| and -7
17 and – 17
17 and | -17|
71 and - 71
Answer:
The answer is C, 17 and | -17|
Step-by-step explanation:
We can solve this using the process of elimination.
Looking at the first one, we know that those | | around the 7 mean to find the absolute value. The absolute value is the number of units the number is from zero, and it is always positive. This means that it is saying 7 and -7. Those are opposites, so we know that this isn't right.
17 and -17 are opposites, since the opposite of a positive is a negative.
The last one is the same. 71 and -71 are opposites. That leaves us with C.
Remember that those | | mean to find the absolute value of. -17 is 17 unites from zero. So is 17 the oppostie of 17? No, so these are not opposites, and therefore are our answer.

what can you say about the unknowns in the equation x+22=y+32
Answer:
x = y + 10
y = x -10
Step-by-step explanation:
For x:
Given: x + 22 = y + 32
Subtract 22 from both sides: x = y + 32 - 22
Answer: x = y + 10
For y:
Given: x + 22 = y + 32
Subtract 32 from both sides: x + 22 - 32 = y
Answer: y = x -10

Graphically, the MEDIAN of a density curve is the equal-area point, the point with half the area under the curve to its left and the other half to its right. The quartiles divide the area under the curve into quarters.
Step-by-step explanation:
The median of a density curve is the equal-areas point: the point that divides the area under the curve in half. The mean of a density curve is the balance point, at which the curve would balance if it were made of solid material.
