Show all work. Calculate and find the x-intercepts of the following function: f(x)=x^2+5x-36

Mathematics

Savatey [412]3 years ago

We can do this by factoring: x^2 + 5x - 36, which is (x+9)(x-4)
We plug f(x) as 0, so (x+9)(x-4)=0, so x = -9 and x = 4
The x-intercepts are (-9, 0) and (4, 0).

Given SinB=.91 find the angle B in radians
labwork [276]

Hello!

As you can see, the opposite side of this angle divided by the hypotenuse is 0.91. To find B, we could multiply by the arcsine using a scientific calculator.

sin^{-1}(0.91)≈65.5

Now, we need to convert this into radians. To do so, we multiply by pi divided by 180.

\frac{\pi}{180} (65.5)≈1.14

Therefore, angle B will form an arc of about 1.14 radians.

I hope this helps!
