Answer:

A = 13.5 cm²

Step-by-step explanation:

use the area of trapezoid:

A = h/2 (b₁ + b₂)

where h = 3 cm

         b₁ = 6 cm

         b2 = 3 cm

plugin values into the formula:

A = 3/2 (6 + 3)

A = 13.5 cm²

[tex]2ab^2-\frac{a^2b^2}{5}=\frac{10ab^2-a^2b^2}{5}[/tex]

Step-by-step explanation:

Given the expression

[tex]2ab^2-\frac{a^2b^2}{5}[/tex]

[tex]\mathrm{Convert\:element\:to\:fraction}:\quad \:2ab^2=\frac{2ab^25}{5}[/tex]

[tex]2ab^2-\frac{a^2b^2}{5}=\frac{2ab^2\cdot \:5}{5}-\frac{a^2b^2}{5}[/tex]

[tex]\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}[/tex]

                 [tex]=\frac{2ab^2\cdot \:5-a^2b^2}{5}[/tex]

                 [tex]=\frac{10ab^2-a^2b^2}{5}[/tex]

Thus,

[tex]2ab^2-\frac{a^2b^2}{5}=\frac{10ab^2-a^2b^2}{5}[/tex]

Find the equation of a line parallel to y = 12 that contains the point (3, 2).

Answers

Answer:

y = 2

Step-by-step explanation:

Let's first write the equation of y = 12 in slope-intercept form. Slope-intercept form is represented as:

y = mx + b

Where...

m: slope

b: y-intercept (the y-value at where the line intercepts the y-axis)

(x, y): any coordinate on the line

This line has a slope of 0 and a y-intercept of 12, therefore its equation is:

y = 0x + 12.

Parallel lines have the same slope. Therefore the equation of the parallel line can be represented as:

y = 0x + b

We need to find b, or the y-intercept.

Let's substitute the point given to us into the equation.

Solve for the y-intercept

y = 0x + b

2 = 0(3) + b

2 = 0 + b

b = 2

Therefore the equation of a line parallel to y = 12 that contains the point (3, 2) is y = 2.

A 12 foot board rests against the wall. The angle that the board makes with the ground is 60 degrees. How far is the base of the board from the wall?

Answers

Answer:

6 foot

Step-by-step explanation:

Since the board is 12foot and the angle makes 60 degrees to the wall, we can assume that it is the 30,60,90 degreees. 30,60,90 degrees triangle makes the side of x, 2x ,and xroot3.

Hence, the board(12foot) is equal to 2x.

x=6

Write the standard form of the equation of the circle with center (−7,1) that passes through the point (−7,9).

Answers

Answer:

(x + 7)² + (y - 1)² = 64

Step-by-step explanation:

Use the equation of a circle, (x - h)² + (y - k)² = r²

Plug in the point and center, then solve for r:

(x - h)² + (y - k)² = r²

(-7 + 7)² + (9 - 1)² = r²

0 + 64 = r²

64 = r²

8 = r

Then, plug in the center and r² into the equation:

(x + 7)² + (y - 1)² = 64

So, (x + 7)² + (y - 1)² = 64 is the standard form of the circle's equation

Insert the graph picture here:
Graph please

Answers

Answer:

y = 33.75 m/s.

Step-by-step explanation:

The graph of the rocket's velocity with respect to  time looks as follows :

[tex]y=0.15x^2[/tex] ...(1)

Where x is time in seconds

We need to find the velocity of rocket after 15 seconds. Put x = 15 in equation (1).

[tex]y=0.15\times (15)^2\\\\=33.75\ m/s[/tex]

Hence, the speed of the rocket after 15 seconds is 33.75 m/s.

Which solution value satisfies the inequality x – 6 ≥ –7?
Question 18 options:

A)

x = –5

B)

x = 0

C)

x = –2

D)

x = –7

Answers

Answer:

B) x = 0

Step-by-step explanation:

To find the solution value that satisfies the inequality x – 6 ≥ –7, you must plug every x value into the x and see which one works.

Plug -5 into x

-5 – 6 ≥ –7

Combine like terms

-11 ≥ –7

This is false, -11 is not greater than or equal to -7.

Plug 0 into x

0 – 6 ≥ –7

Combine like terms

– 6 ≥ –7

This is true, -6 is greater than -7.

Plug -2 into x.

-2 – 6 ≥ –7

Combine like terms

-8 ≥ –7

This is false, -8 is not greater than or equal to -7.

Plug -7 into x.

-7 – 6 ≥ –7

Combine like terms

-13 ≥ –7

This is false, -13 is not greater than or equal to -7.

B) x = 0 is the only solution that is true and works, so that is your answer.
