Identify the initial amount a and the rate of decay r (as a percent) of the exponential function y = 8(1 – 0.15). Evaluate the function
when t = 3. Round your answer to the nearest tenth.
Answer:
Initial amount = 8
Decay rate = 15%
Step-by-step explanation:
Given the exponential function :
y = 8(1 – 0.15)
The general form of an exponential Decay function is :
A = P(1 - r)^t
Where
A = final amout ; P = initial amount ; r = days cay rate ; t = time
Hence, comparing with the equation given :
P = 8 = initial amount
r = 0.15 = 0.15 * 100% = 15% = Decay rate

Answer:
96 square inches
Step-by-step explanation:
Given in a parallelogram
base (b) = 12 inches
height (h) = 8 inches
Now
Area of parallelogram
= b * h
= 12 * 8
= 96 square inches
Hope it will help :)
Answer:
96
Step-by-step explanation:
Area= base x height
= 12 x 8
= 96

In Las Vegas, Nevada, stores charge a 4.6% state sales tax and a 3.65% county sales tax. Yuki is purchasing a handbag priced at $220 before tax.
How much sales tax does Yuki pay for her handbag purchase?
Answer:
$18.15
Step-by-step explanation:
Yuki is paying tax of 4.6% + 3.65% = 8.25%
Converting to decimal form, that is 8.25/100 = 0.0825
Multiply that by the original sale price. 0.0825 x $220 = $18.15 exactly for tax.
The question asks for the tax, NOT for the total she will pay. Please don't get them mixed up.

m= marbles (take note of my user name
Answer:
For each draw, the chances of getting a blue marble are 3 of 7; the chances of getting a red are 4 of 7.
The chances of drawing a blue on both draws is (3/7)^2 or 9/49, and the chances of getting red on both draws is (4/7)^2 or 16/49. But there are other possible outcomes which have to be considered to come to the correct answer.
There are 4 possible outcomes, as follows (although the chances of these outcomes are different):
Comb Chances
RR …….. 16/49
RB …….. 12/49
BR …….. 12/49
BB ……… 9/49
total …….. 49/49
So we can say that the chances of drawing red marbles on each draw are 16/49, and the chances of drawing blue ones on each draw are 9/49. But what about the chances of drawing either both red OR both blue?
I believe we can simply add the 2 probabilities together to come up with a probability of

Probability of two reds = 4/7 x 4/7 = 16/49 = 32.65%
Probability of two blues = 3/7 x 3/7 = 9/49
Probability of the same colour = 25 / 49 = 51.0 %

- Interchange the variables.
x = y - 11
- Solve for y
y = x + 11
- Replace the y with [tex]f^-^1(x)[/tex] to show the final answer.

Wezi has sixty-three $5-bills. He takes the $5-bills to the bank to exchange them for $20-bills. How many $20-bills does Wezi get? Is there money left over? Explain.
Answer: 15
Step-by-step explanation:
From the question, we are informed that Wezi has sixty-three $5-bills. The total amount that he has will be:
= 63 × $5
= $315
We are further told that he takes the $5-bills to the bank to exchange them for $20-bills. Based on this, the number of $20-bills that Wezi get will be:
= $315 / $20
= 15 3/4
Therefore, he will get 15 $20 bills
A camera shop's daily profit is given by P = 3x2 – 3x + 10, where x is the total number of
cameras sold in the day. If they only had profit of $70 today, how many cameras did they
sell?
Answer:
5 cameras they sell
Step-by-step explanation:
P = 3x² – 3x + 10 p = 70
3x² – 3x + 10 = 70
3x² – 3x - 60 = 0
x² - x -20 = 0
(x + 4) (x - 5) = 0
x can't be negative, x = 5
The no of cameras sold if A camera shop's daily profit is given by P = 3x² – 3x + 10, where x is the total number of cameras sold in the day. If they only had a profit of $70 today is 5.
What is equation?A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation. As in, 3x + 5 Equals 15, instances. Equations come in a variety of forms, including linear, quadratic, cubic, and others.
Given:
The equation, P = 3x² - 3x + 10,
If P = 70 then,
70 = 3x² - 3x + 10
x = 5 and -4 but the number of cameras can not be negative
Therefore, The no of cameras sold if A camera shop's daily profit is given by P = 3x2 – 3x + 10, where x is the total number of cameras sold in the day. If they only had a profit of $70 today is 5.

Step-by-step explanation:
M,q 14,4
The value of q in the system of equations 2m-5q=8 and 4m+2q=64 is 4 thus option (A) is correct.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
As per the given system of equations,
2m-5q=8
4m+2q=64
Multiply by 2 into the equation 2m - 5q = 8
4m - 10q = 16
Subtract 4m - 10q = 16 by 4m+2q=64
-10 - 2q = 16 - 64
-12q = -48
q = 4
Hence"The value of q in the system of equations 2m-5q=8 and 4m+2q=64 is 4".
