8.66, you divide 12.99 into 3 and then multiply the result which is 4.33 by 2
Answer/Step-by-step explanation:
Given the function, 
, the table can be completed by substituting the given value of z as follows:
Question 2: z = -7
Question 3: z = -8
Answer:
D. 69.2
Step-by-step explanation:
v= 3.14 ×2.1^2 × 5
v = 69.237
when you round it, it is
69.2 cubic cm
That's exponential decay.
Answer:
u = x²
Step-by-step explanation:
4x⁴ − 21x² + 20 = 0
Substitute u = x² to turn the equation into a quadratic.
4u² − 21u + 20 = 0
You can solve by factoring.
(4u − 5) (u − 4) = 0
u = 5/4 or 4
x² = 5/4 or 4
x = ±½√5 or ±2
