Answer:
30
Step-by-step explanation:
We know that BD = 20 + 5 = 25. Let's call the point where BD and CE intersect point A. Therefore, ΔBAC ≅ ΔBAE by HL (BC = BE = 25 because they are radii, BA and AB are congruent because of the reflexive property). We can use Pythagorean Theorem to find CA. We can write CA² + 20² = 25² so CA = 15 and since CA = AE = 15 and CE = CA + CE, CE = 15 + 15 = 30.
Answer:
f(-2) = 90
Step-by-step explanation:
Plugging in the value of f(x) into the equation:
f(-2) = 5(-2)3^(-2)
f(-2) = 5(-2)(-9) - evaluate the power first
f(-2) = 90 - multiply from left to right to obtain answer
The answer is about 4.43 because by taking 75 percent each time, you are multiplying the already reduced drawing by 25 percent or keeping 75 percent. therefore the equation is 14 * 0.75^4 which leads to 4.43. This is a model for exponential growth
