Answer:

[tex]\frac{f(x + h) - f(x)}{h} = \frac{3}{2}[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \frac{3}{2}x[/tex]

Required

Calculate [tex]\frac{f(x + h) - f(x)}{h}[/tex]

First, we calculate f(x + h)

[tex]f(x) = \frac{3}{2}x[/tex]

[tex]f(x + h) = \frac{3}{2}(x + h)[/tex]

[tex]f(x + h) = \frac{3}{2}x + \frac{3}{2}h\\[/tex]

The equation becomes:

[tex]\frac{f(x + h) - f(x)}{h}[/tex]

[tex]\frac{f(x + h) - f(x)}{h} = \frac{\frac{3}{2}x + \frac{3}{2}h - \frac{3}{2}x}{h}[/tex]

[tex]\frac{f(x + h) - f(x)}{h} = \frac{\frac{3}{2}x - \frac{3}{2}x+ \frac{3}{2}h}{h}[/tex]

[tex]\frac{f(x + h) - f(x)}{h} = \frac{\frac{3}{2}h}{h}[/tex]

[tex]\frac{f(x + h) - f(x)}{h} = \frac{3}{2}[/tex]

Answer:

Step-by-step explanation:

Length of rectangle = 3x + 4

Width of the rectangle = 2x + 6

Perimeter of rectangle = 2(l + b)

45 = 2(3x + 4 + 2x + 6)

45 = 2(5x + 10)

45 = 10x + 20

45 - 20 = 5x

25 = 5x

x = 25/5

x = 5

The approximate standard error of the mean for a sample size of 300 will be option D. 0.46.

Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.

Here the  approximate standard error will be calculated by dividing the standard deviation from the square root of the sample size

Approximate standard error = 7.89/√300=0.455555=0.46

Hence the approximate standard error of the mean for a sample size of 300 will be option D. 0.46.

Answer:

Step-by-step explanation:

Based on the symbols the two triangles there are the equal

Because its two base angles are equal

therefore sum of angle in a triangle is equal to 180°

62°+70°+∠c=180

∴∠c=180-70+62

∠c=180-132

∠c=48

Answer:

m=1

Step-by-step explanation:

Answer:

slope=1

Step-by-step explanation:

To solve this you need to put the equation into the form of y=x+b. To do this you need to get the y and x variables on the opposite sides.

-2y-10+2x=0

First you need to add 10 to both sides.

-2y+2x=10

Then you need to subtract 2x from each side.

-2y=-2x+10

Now divide by -2.

y=x-5

The slope is the coefficient of x, the answer in this case is 1 so the slope of the line is 1.

Answer:

A. x = 18

B. Line AD and line BC are parallel.

Step-by-step explanation:

A. Determination of the value of x.

5x + 3x + 7x + 90 = 360 (sum of angles in quadrilateral.

15x + 90 = 360

Collect like terms

15x = 360 – 90

15x = 270

Divide both side by 15

x = 270/15

x = 18

B. Determination whether or not line AD will be parallel to line BC if drawn to scale.

We shall determine the various angle in the quadrilateral. This can be obtained as follow:

<A = 5x

x = 18

<A = 5(18)

<A = 90°

<B = 90°

<C = 7x

x = 18

<C = 7(18)

<C = 126°

<D = 3x

x = 18

<D = 3(18)

<D = 54°

Summary:

<A = 90°

<B = 90°

<C = 126°

<D = 54°

From the above illustration, we can see that <A and <B are equal (i.e 90°). Thus, line AB is a perpendicular bisector of line AD and line BC. This implies that the distance between line AD and BC are the same at every point. Therefore, line AD and line BC are parallel.

Answer:

3/14

Step-by-step explanation:

Jake sold 42 tickets while Jeanne sold 9 tickets. The questions is asking for the ratio in simplest form the number of tickets Jeanne sold to the number Jake sold. Since we know the amount they sold, let's put it into a ratio factor by Jeannes to Jakes.

9 : 42

To find the simplest form, we need to divide both numbers by their GCF (Greatest Common Factor), which would be 3.

[tex]\frac{9}{3} : \frac{42}{3}[/tex]

3 /14

This means that the ratio from Jeanne's sakes to Jake's sales in simplest form is 3/14

Answer:

<1 = 100

<2 = 80

Step-by-step explanation:

Angle 1 and angle 2 are supplementary

Supplementary angles add to 180 degrees

<1 + <2 = 180

The angles are in a ratio of 5 to 4

Multiply by x to get the measure of each angle

<1 = 5x  <2 = 4x

5x+4x = 180

Combine like terms

9x = 180

Divide by 9

9x/9 =180/9

x =20

<1 = 5x = 5*20 = 100

<2 = 4x = 4*20 = 80

Answer:

m1 = 122
