Answer:

(3.4,3)

Step-by-step explanation:

(2.7+4.1÷2, -1.2+7.2÷2)

=(6.8÷2, 6÷2)

=(3.4,3)

Answer:

D: 9.75 * 10^6

Step-by-step explanation:

You can make it easy for yourself if you write both answers in the same form:

(9.4 * 10^6) = (9.4 *10 *  10^5 = 94*10^5) and (3.5 * 10^5) stays the same.

We can now add those numbers up easier:

(94*10^5) + (3.5*10^5) = ( 94 + 3.5 ) * 10^5 = ( 97.5 * 10^5 )

but this answer is not in the option list. We have to perform the same trick as in the beginning, but than the other way around:

(97.5 * 10^5) = (9.75 * 10) * 10^5 = 9.75 * 10^6,

which is exactly option D

Answer: im pretty sure its 4 from 3/4

Step-by-step explanation:

Solution

- The inequality is:

- The graph of the inequality is graphed using a graphing calculator as follows:

So we are told that the height of the innertube in meters is given by:

The minimum height is 2 meters, the maximum is 8 meters and the time between two consecutive maximums is 12 seconds. Here is important to note a few properties of the sine. First of all, the minimum value of sin(bx) is -1 and its maximum value is 1. Then the height of the innertube is minimum when sin(bx)=-1 and maximum when sin(bx)=1. With these two values we can build two equations for a:

So we have:

Substracting 5 from both sides of the second equation we get:

Using this in the first equation gives us:

Which confirms that a=3. Now we have to find b. For this purpose we can recal another property of the sine. Its period i.e. the distance (in this case the time) between two consecutive maximums is given by:

Since we know this time is 12 seconds we get:

If we multiply both sides by b and divide them by 12 we get:

So we have:

Which means that the answer is the second option.

The point-slope form of the equation of a line is given by the following expression:

y - y1 = m(x - x1)

Where m is the slope of the line and (x1, y1) is a point where the line passes through.

The slope of the line can be determined with the following formula:

Where (x1, y1) and (x2, y2) are two points where the line passes through. In this case we are told that the line passes through the points (-2,-6) and (6,5). By replacing the x and y coordinates of these points into the formula of the slope, taking x1 as -2, x2 as 6, y1 as -6 and y2 as 5, we get:

Then, the slope of the line equals 11/8, by replacing 11/8 for m into the slope-point form, we get:

y - y1 = 11/8(x - x1)

By taking one of the points, for example (-2,-6), we replace the x and y-coordinates that appear in the equation of the line, to get:

y - (-6) = 11/8(x - (-2))

y + 6 = 11/8 (x + 2)

Then, the equation of the line in slope-point form is y + 6 = 11/8 (x + 2)

This eliminates all of the options except for d.

Answer:

17/12

1 5/12

Step-by-step explanation:

If we make the fractions have common denominators, this problem is a piece of cake.

First, since the closest multiple of 3 and 4 is 12, put 12 instead of the 3 and 4.

Since 3x4=12, multiply 2x4.

2x4=8.

So the first fraction would be 8/12

Next, since the 4 turned into a 12, multiply 3 by 3.

3x3=9

So the second fraction would be 9/12.

Now, add 9/12 and 8/12 together.

9/12+8/12=

17/12

1 5/12

The other point through which a line that describes a proportional relationship must pass is the point (0, 0)

A proportional relationship is one in which each the ratio of the x and y–values of each point on the line of the function is a constant.

The given relationship described by the line = A proportional relationship

The given point on the line = (6, 2)

Required; The other point through which the line must pass.

Given that the relationship described by the line, the ratio of all points on the line is a constant and each point (x, y) can be expressed in the form;

y = K•x

Which gives;

[tex] \displaystyle{ K = \frac{y}{x} }[/tex]

Where, K is a constant which is not equal to zero.

From the zero product property, which states that the product of all numbers and zero is also zero, we have;

When x = 0, k × 0 = 0 = y

A point through the line must pass is therefore; (0, 0)

Long Multiplication

1. Arrange the numbers one on top of the other and line up the place values in columns. The number with the most digits is usually placed on top as the multiplicand.

This will be written as follows:

467

x 48

---------------

2. Starting with the ones digit of the bottom number, the multiplier, multiply it by the last digit in the top number.

This product is 8*7 = 56

3. If that answer is greater than nine, write the ones place as the answer and carry the tens digit.

We should write 6 and carry 5:

You have the following expression:

log(z) - log(18)

By the properties of logarithms, consider that the subtraction of two logarithms is equal to the logarithm of the quotient of the arguments:

log(z) - log(18) = log(z/18)

Hence, the answer is log(z/18)

Let g represent gallons of water and let L represent loads.

Here, the gallons of water varies directly with the number of loads, thus we have:

g ∝ L

Now introduce a constant k:

g = kL

65 gallons is used to wash 5 loads, thus we have:

65 = k * 5

Let's solve for k:

65 = 5k

Divide both sides by 5:

To find the amount of water that will be used to wash 8 loads, we have:

g = kl

We are to find g, substitute 13 for k and 8 for l:

g = 13 x 8

g = 104

Therefore, to wash 8 loads, 104 gallons of water is needed.

  3 ≤ x < ∞

Step-by-step explanation:

You want the domain of a square root function shifted right 3 units and up 1 unit. It goes through points (3, 1), (4, 2) and (7, 3).

The domain of a function is the set of values of the independent variable for which the function is defined. It is the horizontal extent of the graph.

The graph of the given square root function extends to the right from x=3.

The domain is 3 ≤ x < ∞. In interval notation, it is [3, ∞).

Given:

The equations are:

a.) y = 2x + 7, b.) y = 3/5x + 1, c.) 3x + 2y = 6, d.) y = x^2

To determine what in the equation of part (d) makes its different, we first note that the graph for part (d) is a parabola, which is a curve with an upward opening. In addition, we also note that the power of x in the equation of part (d) is 2, while the other three graphs have a power of 1.

Therefore, the answer is:

So,

Final answer:

Hence, the value of the range is 5.

Answer:

99

Step-by-step explanation:

You can set up a proportion, and solve for the variable (missing grade in this case):

[tex]\frac{88+90+94+89+x}{5} =92[/tex]

Each grade is already in the database, so it can serve as the constant, and five is the denominator because to get a mean average, you must divide all the values by the number of values that exist. So, in this case, it would be 5, 4 including the missing grade, making it 5. Set the equation equal to 92, because that's her desired average, then just solve for x.

Multiply the 5 on both sides.

-> 5 cancels on left, and 5 multiplies with 92 to get 460.

[tex](5)\frac{88+90+94+89+x}{5} = 92(5)[/tex]

Add all constants on the left side of the equation.

-> 88+90+94+89=361

[tex]361+x = 460[/tex]

Subtract that new constant (361) from the 460, and you get x=92.

-> 460-361=99

[tex]x=99[/tex]

GIVEN:

We are told that a school wants to estimate the number of students who drive to school.

Required:

To determine which survey would best represent the entire student population..

Step-by-sep solution;

Taking a sample of 11th graders would not correctly represent the entire student population. The result from this survey would at best represent the preference of 11th grade students and not other grades. The same thing applies to a survey of the science club. The science club cannot accurately represent all students (including other clubs).

However, a survey of 25 students from the school would best represent the entire student population since there is a probability of every category of student being represented.

Therefore,

25 students are randomly selected from the school; 4 drive to school.

Part (B):

There are 1750 students at Lincoln High. Use the answer above to estimate the number of students who drive to school.

If the sample of 25 students has 4 students who drive to school, then to estimate the entire population based on this;
