Step-by-step explanation:

Given:

Find f(g(x)):

[tex]\\ \tt\hookrightarrow f(x)=-x^2-1[/tex]

[tex]\\ \tt\hookrightarrow g(x)=x+5[/tex]

Now

[tex]\\ \tt\hookrightarrow f(g(x))[/tex]

[tex]\\ \tt\hookrightarrow f(x+5)[/tex]

[tex]\\ \tt\hookrightarrow -(x+5)^2-1[/tex]

[tex]\\ \tt\hookrightarrow -(x^2+10x+25)-1[/tex]

[tex]\\ \tt\hookrightarrow -x^2-10x-25-1[/tex]

[tex]\\ \tt\hookrightarrow -x^2-10x-26[/tex]

we know the Inn is charging 155.82 and that's 100% plus 6%, namely 106% of an amout of say that is "x", being the 100%.

since we know that 155.82 is 106%, what is "x"?

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 155.82&106\\ x&100 \end{array}\implies \cfrac{155.82}{x}=\cfrac{106}{100}\implies \cfrac{155.82}{x}=\cfrac{53}{50} \\\\\\ 7791=53x\implies \cfrac{7791}{53}=x\implies 147=x[/tex]

Answer:

Step-by-step explanation:

Hypotenuse² =base² + altitude²

(3x + 4)² = (2x + 1)² + (3x)²

{Use (a+b)² = a² + 2ab + b²}

(3x)² + 2*3x+4 + 4² = (2x)² + 2*2x*1 + 1² + 9x²

9x² + 24x + 16 = 4x² + 4x + 1 + 9x²

9x² + 24x + 16 = 13x² + 4x + 1

0 = 13x² + 4x  + 1 - 9x²  - 24x - 16

13x² - 9x² + 4x - 24x +1 - 16 = 0

4x² - 20x - 15 = 0

a = 4 ; b =-20  ; c = -15

D = b² - 4ac  = (-20)² - 4*4*(-15) = 400 + 240 = 640

√D = √640 = 25.30

[tex]x=\dfrac{-b+\sqrt{D}}{2a} \ ; \ x=\dfrac{-b-\sqrt{D}}{2a}\\\\\\x=\dfrac{20+25.30}{2*4} \ ; \ x=\dfrac{20-25.30}{2*4}\\\\\\x=\dfrac{45.30}{8} \ ; \ x =\dfrac{-5.30}{8}\\\\[/tex]

x = 5 .66   ; x = -0.66

Ignore x = -0.66 as length of a side cannot be negative

Answer : x = 5.66

Answer:

$26.87

Step-by-step explanation:

if the shirt was 35% off, then you paid 65% of the cost

that value can be found by:

39 x .65 = 25.35 (this is the amount paid for the shirt)

sales tax of 6% on 25.35 is:

.06 x 25.35 which equals 1.52

25.35 + 1.52 = 26.87

Answer:

the answer you are looking for is-10

Step-by-step explanation:

The number of listeners is given from the total number of listeners and

the ratio of the listeners between the two stations.

Required:

Given:

The daily listening audience of the AM station = 4 × The audience of the FM sister station

The number of people that listen to the two stations = 105,000

Required:

The number of listeners of the FM station

Solution:

The ratio of the listeners is 1:4

Let x represent the number of listeners of the FM sister station, we have;

The number of listeners of AM radio station = 4·x

Which gives;

4·x + x = 105,000

5·x = 105,000

[tex]x = \dfrac{105,000}{5} = \mathbf{21,000}[/tex]

The number of listeners of he radio station = 21,000 × 4 = 84,000

Answer:

-2/3= x

Step-by-step explanation:

square all the terms on both sides to get rid of the radicals:

[tex]1^{2} + (\sqrt{1-x} )^{2} = (\sqrt{2x+4}) ^{2}[/tex]

exponent 2 and the radical cancel each other:

1 + 1 - x = 2x + 4

2 - x = 2x + 4

like terms on each side ( when you move one term tp the other side, it changes its sign ):

2-x = 2x+4

2-4 = +x +2x

-2 = 3x

now to keep the x alone, divide both sides by 3:

-2/3 = 3x/3

-2/3= x

The area of a shaded region is the amount of space it occupies

The measurement that is closest to the area of the shaded region is 19 square inches

Start by calculating the area of the big rectangle.

Assume the dimensions of the rectangle are 10 by 15 inches.

The area would be

[tex]A_1 =10* 15[/tex]

[tex]A_1 = 150 in^2[/tex]

Next, calculate the area of the small rectangle.

Assume the dimensions of the rectangle are 13 by 10 inches.

The area would be

[tex]A_2 =13* 10[/tex]

[tex]A_2 =130 in^2[/tex]

Next, calculate the difference between both areas

[tex]d = 150 - 130[/tex]

[tex]d = 20\ in^2[/tex]

19 is the closest to 20

Hence, the measurement that is closest to the area of the shaded region is 19 square inches (using the assumed values)

No.

Step-by-step explanation:

It's not reasonable because 0.42 in decimals makes it smaller because of more digits.

Answer: B' (5,8), C' (3,1)

Step-by-step explanation:

You can use the points A' (-1,8) and A (-2,-3) to find how many units point A was translated.

-2 + 1 = -1

-3 + 11 = 8

Then, you simply add 1 to the x-values of points B and C and 11 to the y-values of points B and C to get B' (5,8), C' (3,1).
