Answer:

there is 16.08 foot high does the ladder reach on the building

Step-by-step explanation:

The computation of the high does the ladder reach on the building is shown below:

Given that

length of the ladder = 17 ft

angle -between the ground and the ladder = 75 degrees

Based on the above information

Here we used the trig-ratio to calculate the same

Sin \theta  = \frac{oppo}{hyp} \\\\Sin 71^{\circ} = \frac{h}{17}

0.946 × 17 = h

The height is 16.08 foot

Hence, there is 16.08 foot high does the ladder reach on the building

For which equation will f(-2)= -6?
Mila [183]

Answer:

C. f(x)=4x^3+6x^2-x

Step-by-step explanation:

Lets plug in -2 into each of these equation to see which one gives us the solution of -6

A. f(x)=x^3+x

f(-2)=(-2)^3+(-2)\\\\f(-2)=-8-2\\\\f(-2)=-10

B. f(x)=x^4-5x

f(-2)=(-2)^4-5(-2)\\\\f(-2)=16+10\\\\f(-2)=26

C. f(x)=4x^3+6x^2-x

f(-2)=4(-2)^3+6(-2)^2-(-2) \\\\f(-2)=4(-8)+6(4)+2\\\\f(-2)=-32+24+2\\\\f(-2)=-6

D. f(x)=-3x^3-4x^2+4x

f(-2)=-3(-2)^3-4(-2)^2+4(-2)\\\\f(-2)=-3(-8)-4(4)-8\\\\f(-2)=24-16-8\\\\f(-2)=0

As we can see, function C was the only one that gave us the value of -6, so that is our answer.

Consider, pls, this solution:

If given a equation:
-12x²+11x-3=0, then
12x²-11x+3=0
D=b²-4ac=121-12*12=-23<0
\left[\begin{array}{ccc} x= \frac{11-i \sqrt{23}}{24}  \\ \ x= \frac{11+i \sqrt{23}}{24}  \end{array}\right
