Answer:

<u>f</u><u>(</u><u>-</u><u>2</u><u>)</u><u> </u><u>+</u><u> </u><u>9</u><u> </u><u>is</u><u> </u><u>1</u><u>9</u>

Step-by-step explanation:

f(x) =  - 3x - 2

when x is -9:

f( - 2) =  - 3( - 2) - 2 \\ f( - 2) = 10

sum up with 9, f(-2)+9:

f( - 2) + 9 = 10 + 9 \\  = 19

Which set of transformations is needed to graph f(x) = -0.1cos(x) - 4 from the parent cosine function?
Ostrovityanka [42]

Answer:

The correct option is;

Reflection across the x-axis, vertical compression by a factor of 0.1, vertical translation 4 units down

Step-by-step explanation:

The given function is f(x) = -0.1·cos(x) - 4

The parent cosine function is cos(x)

Therefore, f(x) = -0.1·cos(x) - 4 can be obtained from the parent cosine function as follows;

The negative sign in the function gives a reflection across the x-axis

The 0.1 factor of the cosine function gives a compression of 0.1

The constant -4, gives a vertical translation 4 units down

Therefore, the correct option is a reflection across the x-axis, vertical compression by a factor of 0.1, vertical translation 4 units down.

Expand and simplify (x+5)(x-2)
lukranit [14]

Answer:

x² + 3x - 10

Step-by-step explanation:

Each factor in the second factor is multiplied by each term in the first factor, that is

x(x - 2) + 5(x - 2) ← distribute each parenthesis

= x² - 2x + 5x - 10 ← collect like terms

= x² + 3x - 10

Find the distance to the nearest tenth
grin007 [14]

Answer:

d=11.2

Step-by-step explanation:

d=\sqrt{(x2-x1)^{2}+(y2-y1)^{2} \\ }

d=\sqrt{(6-(-4)^{2}+(-3-2)^{2}  }

d=\sqrt{10^{2}+5^{2}  }

d=\sqrt{100+25}

d=\sqrt{125}

d=11.18

d=11.2
