The rate of interest required to achieve the conditions set forth is 7.1773%.

<h3>What is the interest rate?</h3>

The interest rate is the rate at which the investment increases. The formula that can be used to determine interest rate is:

g = (FV / PV)^(1/N) - 1

Where:

FV = future value = $32,000
PV = present value = $8000
n = number of years

4^(1/20) - 1 = 7.1773%

The school band is comprised of middle school students

iogann1982 [59]

Answer:if there are 7 HS students for every 2 MS students and there are 18 MS students...

18/2 = 9

9(7) = 63

So, there are 18 + 63 = 81 total students.

Since we had 9 parts last year also (1:8), 81/9 = 9 students are in each part. 8 students in each part are HS and one is MS.

8(9) = 72 HS students last year.

72 - 63 = 9 fewer HS students than last year.

Hope this helps!

The advertised size of a pizza is the length of its diameter. (An 8-inch pizza has a diameter of 8 in)Q1: What is the area of a

Alexxandr [17]

<span>In this question, we assume the pizza is a circle with radius r and diameter d. The radius is also known as (d/2). The area of a circle is A=pie*r^2. Q1: The area of a 16 inch pizza is A = pie * (16/2)^2 = pie * 8^2 = pie *64 = 201.06 in^2. Q2: To determine the cost per slice, just divide the total cost by the number of slices. In this case you would divide 12.50 by 8 (total slices) to get 12.50/8=$1.56/slice. Q3: The cost per square inch of the pizza would be total cost divided by the total area in square inches. This would give you 12.50/201.06 = $0.06 per square inch.</span>

Which equation represents the function graphed on the coordinate plane? g(x) = |x Ă˘â‚¬"" 4| Ă˘â‚¬"" 10 g(x) = |x 4| Ă˘â‚¬"" 10

natta225 [31]

The equation which represents the function graphed on the coordinate plane given is,

$|x+4|-10$

Thus, option B is the correct option.

Given-

The general form of the equation is,

$y=a|x-h|+k$

Let's compare it with the graph given. The graph opens upward with a slope of 1. Hence the value of $a$ is 1.

$y=|x-h|+k$

The vertex of the graph is shifted -4 to the right. Thus the value of the $h$ is -4.

$y=|x-(-4)|+k$

$y=|x+4|+k$

The graph is 10 down from the origin and hence, the value of k is -10.

$y=|x+4|-10$

Hence, The equation which represents the function graphed on the coordinate plane given is,

$|x+4|-10$

Thus, option B is the correct option.
