Angle from the base of the shadow to the top of the flagpole is 25 degrees

tan x = opposite / adjacent

x = 25 degrees
opposite = ?
adjacent = 137

Rearrange equation

tan(25) x 137 = 63.88 ft

The flagpole is 63.88 feet high

3. Graph y=-4x² – 2 and its inverse. (1 point)

madam [21]

Function and its inverse was graphed.

Step-by-step explanation:

y = -4x²- 2

To find the inverse function of y = -4x²- 2 we have to transform the formula to calculate x in terms of y.

y = -4x²- 2

-4x² = y - 2

x = √(y-2) / -4

Now we can change the letters to follow the convention that x is the independent variable and y is the function's value:

y = √(x-2) / -4

Now we have to draw the graph as,

It was side by side that is LHS is the function and the RHS is its inverse.

Marlene's taxable income is $95,000. Use this tax schedule to calculate the total amount she owes in taxes. A. 12,88.75 B. 17,90

zheka24 [161]

The answer is C.

Since here taxable income is over $77,100 and below $160,850, her tax is $15,698.75 + [.28*($95,000 - $77,100)].

Tax = $15,698.75 + [.28*($17,900)].
= $15,698.75 + [$5012].
= $20,710.75

If you are solving the equation by factoring, which of the following equations would you use the zero product property on?

Artist 52 [7]

Answer:

(x + 5)(x + 10) = 0

Step-by-step explanation:

When you solve for the equation: $\frac{1}{x-4}-\frac{14}{x+2}+1=0$ , you get that the answer is $x=10,\:x=5$ .
