Answer:
f(-5) = -43
Step-by-step explanation:
Step 1: Define
f(x) = -2x² + 7
f(-5) is x = -5
Step 2: Substitute and Evaluate
f(-5) = -2(-5)² + 7
f(-5) = -2(25) + 7
f(-5) = -50 + 7
f(-5) = -43
Answer:
The equation used to predict the number of people living in the town after x years is y = 32,000 (1.08)x
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Initial population: 32,000
</em>
- <em>Growth per year: 8%
</em>
So, to obtain "y" (the number of people living in the town after x years), we have to multiply the initial population by 1+ 0.08 (the growth rate is 8%/100=0.08 and the original value) and the number of years (x).
Mathematically speaking:
y = 32,000 (1+0.08) x
y= 32,000 (1.08) x
The equation used to predict the number of people living in the town after x years is y = 32,000 (1.08)x
Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 4)² + (y - 1)² = 25 ← is in standard form
with centre = (- 4, 1 ) and r = 
= 5 → A
