The function A(b) relates the area of a trapezoid with a given height of 10 and
Natali [406]

Answer:

B(a)=\frac{a}{5} -7

Step-by-step explanation:

The input it taken as the unknown base value, while the output here is the area of the trapezoid. b is therefore the base value, and A( b ) is the area of the trapezoid. Let's formulate the equation for the area of the trapezoid, and isolate the area of the trapezoid. To find the inverse of this function, switch y ( this is A( b ) ) and b, solving for y once more, y ➡ y ⁻ ¹.

y = height * ( ( unknown base value ( b ) + 7 ) / 2 ),

y = 10 * ( ( b + 7 ) / 2 )

Now switch the positions of y and b -

b = 10 * ( ( y + 7 ) / 2 ) or b=\frac{\left(y+7\right)\cdot \:10}{2} - now that we are going to take the inverse ( y ⁻ ¹ ) or B( a ), b will now be changed to a,

y+7=\frac{a}{5},

y^{-1}=\frac{a}{5}-7 = B(a)

Therefore the equation that represents the inverse function will be the following : B(a) = a / 5 - 7

Select the statement in if-then form.
SashulF [63]
The correct statement is C. <span>If an angle is an acute angle, then the angle measures less than 90 degrees. 
A and B are obviously incorrect, and D is incorrect because it can be other angle as well, not just acute. </span>
