The radius of a circle can be approximated using the expression √(A/3). A circular kiddie swimming pool has an area about 28 squ

are feet. An inflatable full-sized circular pool has an area of about 113 square feet. How much greater is the radius of the full-sized pool than the radius of the kiddie pool? round to the nearest whole number.
It says Hint: First find the radius of each pool by substituting for A in the expression. Divide by 3 before approximating square root.

Ainat [17]

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

After years of maintaining a steady population of 32,000, the population of a town begins to grow exponentially. After 1 year an
elixir [45]

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>
  • <em>Years: x </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

5. Find the center and radius of the circle with the given equation.
leonid [27]

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 = \sqrt{25} = 5 → A
