Answer: [tex]\frac{6}{2}[/tex]
Step-by-step explanation:
1. Use this [tex]\frac{f(b)-f(a)}{b-a}[/tex] to find the average rate of change
2. Average rate of change = [tex]\frac{f(8)-f(6)}{8-6}[/tex]
3. [tex]f(8) = - 4[/tex] and [tex]f(6) = -10[/tex] (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))
4. Replace -4 to f(8) and -10 to f(6)

Answer:
C
Step-by-step explanation:
Begin by isolating y
-6y = - x - 1
Divide everything by -6
y = -x/-6 - 1/-6
y = x/6 + 1/6
Now you want the perpendicular
m1 * m2 = - 1
m1 = 1/6
1/6 * m2 = -1
multiply by 6
m2 = - 6
That's C

Find the total surface area of the following
cone. Leave your answer in terms of m.
12 cm
5 cm
Hint: Surface Area of a Cone = url + B
Where l = slant height, and B = area of the base
S.A. = [? ]n cm?
Answer:
[tex]S.A.=90\pi~cm^2[/tex]
Step-by-step explanation:
Surface Area of a Cone
Given a cone of base area B and slant height L, the surface area can be calculated with the formula:
[tex]S.A.=\pi rL +B[/tex]
The cone presented in the image has a circular base of radius r=5 cm, thus its base area is:
[tex]B=\pi r^2[/tex]
[tex]B=\pi 5^2[/tex]
[tex]B=25\pi~cm^2[/tex]
The slant height can be calculated as the hypotenuse of a right triangle with legs 5 cm and 12 cm by using Pythatgora's Theorem:
[tex]L^2=5^2+12^2[/tex]
[tex]L^2=25+144=169[/tex]
Taking square roots
[tex]L = \sqrt{169}[/tex]
L = 13 cm
The surface area is:
[tex]S.A.=\pi (5~cm)*13~cm +25\pi~cm^2[/tex]
Operating:
[tex]S.A.=65\pi~cm^2 +25\pi~cm^2[/tex]
[tex]\mathbf{S.A.=90\pi~cm^2}[/tex]

Step-by-step explanation:
8000(1+.05)^4= 9724.05
sry if im wrong :)
The amount after 4 years will be equal to $9,724.05
What is compound interest?The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest.
Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-
Given that Mr.Turner invested $8,000 in an account for his daughter’s college education. The account pays 5% interest, compounded yearly.
The amount after 4 years will be calculated as:-
[tex]A = P ( 1 + \dfrac{r}{100})^{nt}[/tex]
[tex]A = 8000 ( 1 + \dfrac{5}{100})^{4}[/tex]
A = 9724.05
Therefore, the amount after 4 years will be equal to $9,724.05.

12. The probability a basketball player making a free-throw
is .84, what are the odds against making a free-throw?
Answer:
The odds against making a free throw are: 0.1905 or 0.16:0.84
Step-by-step explanation:
The odds can be categorized into two categories
Odds-againstOdds-in favourThe odds against is the ratio of probability of failure to probability of success.
Given
Probability of making a free throw = P = 0.84
Probability of not making a free throw = Q = 1-P = 1-0.84 = 0.16
The formula for odds-against is:
[tex]Odds-against = \frac{0.16}{0.84}\\= 0.19047..\\=0.1905[/tex]
Hence,
The odds against making a free throw are: 0.1905 or 0.16:0.84

20. Given f(x) = 2x + 9, if f(x) = 15, find x.
Answer:
the answer is located in the screenshot that is attached.
Step-by-step explanation:
The work is also in the screenshot attached. Hoped this helped!
The value of x if f(x) = 15 in the given function is 3
From the question,
We were given the function f(x) = 2x + 9
To determine the value of x if f(x) = 15, we will put f(x) to be equals to 15 and then solve for x in the equation
That is,
f(x) = 2x + 9
Since f(x) = 15
∴ 15 = 2x + 9
Now, to solve the above equation,
First, subtract 9 from both sides
That is,
15 - 9 = 2x +9 -9
6 = 2x
Then, we can write that
2x = 6
∴ x = 6 ÷ 2
x = 3
Hence, the value of x if f(x) = 15 in the given function is 3

First, you want to set up a proportion.
8/24 = 10/y
Cross multiply to get
240 = 8y, then divide 8 from both sides to get y = 30.
Sophie buys x packages of graph paper for $2.55 each (tax included). She pays with a $20 bill.
Write an algebraic expression to represent the amount of change the cashier should give back to Sophie.
Answer:
x=$20/$2.55.
Step-by-step explanation:
if each package is $2.55 then and it cost $20 then you will have to divide the numbers wich will give u x
Answer:
20 - 2.55x
Step-by-step explanation:
20 is the dollar bill Sophie bought the packages with, x represents the number of packages bought and 2.55 is the price for each, so by subtracting 20 by the cost of the total packages results in the amount of change the cashier should give back to Sophie.
For example, if Sophie bought 3 packages of graph paper with a $20 bill the cashier should give back to Sophie $12.35.
20 - 2.55 (3)
20 - 7.65
12.35

You decide to join a tennis class. The initial entrance fee is
$100, and a $10 fee every month you want to take the class.
How much will it cost for five months?
Given :
Initial entrance fee of tennis class, E = $100 .
Fee of every month, F = $10 .
To Find :
How much will it cost for five months.
Solution :
Let, number of months are n and cost of class is y.
So, linear equation is given by :
y = 10n + 100 ...1)
To know the cost of 5 month, putting value of n = 5 in equation 1) we get :
y = ( 10×5) + 100
y = 50 + 100
y = $150
Therefore, the cost of five month fee in tennis class is $150.
Hence, this is the required solution.
