Answer:</h2>
[C] 90°.
<u>It is Because ∠ACB is formed by the diameter of the semicircle</u>.
<u>And we already know that, the angle formed by diameter measure 90° to the circle or semicircle</u>.
Answer:
324, -972, 2916
Step-by-step explanation:
Divide a number by the previous number to find r.
r = -12/4 = -3
Multiply a number by r to find the next number.
-108 * (-3) = 324
324 * (-3) = -972
-972 * (-3) = 2916
Answer: 324, -972, 2916
False, Theoretical is what should happen, like rolling a dice, you should see every side once in six throws. Experimental is where the results are random.
The zero of the given function is x = 12 and. -3
<h3>Zeros of a function</h3>
Given the function expressed below;
F(x) = x^2 − 9x − 36
The zero of the function is the. point where f(x) = 0
x^2 − 9x − 36 = 0
Factorize to have;
x^2-12x+3x-36=0
X(x-12)+3(x-12)=0
(x-12)(x+3)= 0
Determine the zeros
x = 12 and. -3
Hence the zero of the given function is x = 12 and. -3
