Answer:

Option C

Step-by-step explanation:

Given function is,

f(x) = 9x² - 12

Steps to find the inverse of the given function,

Step 1,

Write the function in the form of an equation,

y = 9x² - 12

Step 2,

Interchange variables 'x' and 'y' in the equation,

x = 9y² - 12

Step 3,

Solve this equation for 'y',

x = 9y² - 12

9y² = x + 12

[tex]y^2=\frac{1}{9}(x + 12)[/tex]

[tex]y=\pm\sqrt{\frac{1}{9}(x + 12)}[/tex]

[tex]y=\pm\frac{\sqrt{(x+12)}}{3}[/tex] Here, x > -12

Step 4,

Covert this equation into function,

[tex]g(x)=\pm\frac{\sqrt{(x+12)}}{3}[/tex]

Therefore, Option C will be the answer.

Answer:

w = 15

Step-by-step explanation:

p = 2l + 2w

76 = 2(5x - 2) + 2(3x)

76 = (10x - 4) + (6x)

Combine like terms

76 = 16x - 4

add 4 to both sides

80 = 16x

Divide both sides by 16

5 = x

x = 5

w = 3x

w = 3(5)

w = 15

Answer:

The circumference formula is C=3.14d

Step-by-step explanation:

To find the diameter with the radius you need to multiply 2.09 x 2.

Now you have 4.18, this is your diameter, you're now going to multiply 4.18 with pi, which is typically 3.14, if it's not that it's 22/7.

Your answer would be 13.12

Answer:

Step-by-step explanation:

Given,

No. of families = 75

Out of 75 no. of families had cars = 42

Out of 1, no. of families can have cars

[tex] = \frac{42}{75} [/tex]

Therefore,

Out of 200 families, no. of families had cars

[tex] = 200 \times \frac{42}{75} [/tex]

[tex] =200 \times \frac{14}{25} [/tex]

= 8 × 14

= 112

Hence,

option B is correct as 112 families have cars out of 200 families (Ans)

Answer:

50 inches

Step-by-step explanation:

Hi there!

[tex]P=2l+2w[/tex] where l is the length of the rectangle and w is the width of the rectangle

Plug in the length (15 inches) and width (10 inches)

[tex]P=2(15)+2(10)\\P=30+20\\P=50[/tex]

Therefore, the perimeter of the frame is 50 inches.

Answer:

All real numbers greater than or equal 2.

Step-by-step explanation:

There is a closed circle on the number 2,which means that it is included in the range. The line is increasing, meaning that all real numbers greater than or equal to 2 is the range.

Answer:

B' = (3, -3)

Step-by-step explanation:

If the coordinate (a,b) is dilated by a factor of k, the resulting coordinate will be ()ka, ka)

Given the coordinate (1, -1). When dilated by a factor of 3, the resulting coordinate will be;

B' = 3B

B' = 3(1, -1)

B' = (3(1), 3(-1))

B' = (3, -3)

Answer:

could u upload the figure as well?

Step-by-step explanation:

[tex]b = 5, \: g = 3, \: r = 8[/tex]

[tex]total = 5 + 3 + 8 = 16[/tex]

[tex]p(b) = \frac{5}{16} [/tex]

[tex]p(g |without \: replacement|) = \frac{3}{16 - 1} = \frac{3}{15} = \frac{1}{5} \\ [/tex]

[tex]p(b \: and \: g) = \frac{5}{16} \times \frac{1}{5} = \frac{1}{16} [/tex]

Answer:

A=16.3 ft²

Step-by-step explanation:

we are given a composite figure, composing of a triangle and a semicircle

first, let's find the area of the triangle

we are given the height (5 ft) and the base of the triangle (4 ft)

the formula for the area of the triangle is given as bh/2, where b is the base and h is the height

substitute the known values into the formula

[tex]A_{triangle}[/tex]=bh/2

[tex]A_{triangle}[/tex]=(5*4)/2

[tex]A_{triangle}[/tex]=20/2=10 ft²

so the area of the triangle is 10 ft²

now to find the area of the semicircle:

the area of a semicircle is half the area of a circle; the area of a circle is given as πr², where r is the radius. Therefore, the area of a semicircle is (πr²)/2

4 ft isn't just the base of the triangle; it's also the diameter of the semicircle

however, we need the radius

the radius is half the diameter value

r=d/2

r=4/2

r=2 ft

so the radius is 4 feet

now find the area of the semicircle. Don't substitute for π just yet.

[tex]A_{semicircle}[/tex]=(πr²)/2

[tex]A_{semicircle}[/tex]=(π*2²)/2

[tex]A_{semicircle}[/tex]=4π/2

[tex]A_{semicircle}[/tex]=2π

π is often substituted as 3.14 or 22/7

so if we used 3.14 for instance:

[tex]A_{semicircle}[/tex]=6.28; rounded to the nearest tenth, that's 6.3 ft²

now add the two areas together to get the area of the composite figure

[tex]A_{compositefigure}[/tex]=[tex]A_{triangle}[/tex]+[tex]A_{semicircle}[/tex]

[tex]A_{compositefigure}[/tex]=10+6.3=16.3 ft²

Hope this helps! Good luck on your assignment!!
