A singer earns $4 million in 2015. During the next 10 years, the earnings increase 7% each year. A. Write an exponential growth model giving the earnings y (in millions of dollars) t years after 2015. Write the base of the model as a decimal. An exponential growth model is y= b. In which year will the player's earnings first exceed $7,000,000?
Answers
Answer:
ninth year
Step-by-step explanation:
Given the general form of an exponential equation;
P = a(1 +r)^t
We can now write in this particular case;
y = 4 * 10^6(1 + 0.07)^t
The year in which y reaches 7 * 10^6 dollars is
7 * 10^6 = 4 * 10^6 (1 + 0.07)^t
7 * 10^6/4 * 10^6 = (1 + 0.07)^t
1.75 = (1 + 0.07)^t
ln(1.75)= ln(1 + 0.07)^t
ln(1.75) = t ln(1 + 0.07)
0.5596 = 0.06766t
t = 0.5596/0.06766
t = 8 years
So, in the ninth year;
y = 4 * 10^6 (1 + 0.07)^t
y = 4 * 10^6 (1 + 0.07)^9
y = 7.35 * 10^6
Hence, the player's earnings first exceed $7,000,000 in the ninth year.

Okay so what you do is multiply 6*9*4.5 together and that'll give you 243 as the volume of the prism. I'm not sure what it is in decimal. I'm guessing 24.3
I'm so sorry if this is incorrect.
Have a great day! <3
Answer:
121.5 ft^2
Step-by-step explanation:
To find Volume of Triangular prism, find the area of the triangular shape first.
Step 1: 6 x 4.5 = 27(square)
Step 2: 27 x .5 = 13.5(triangle)
13.5 x 9(the width) = 121.5
Because volume is length x width x height.
The height and length is 6 x 4.5 in this problem.
Note : I did "x.5 " because I needed to divide 27 by two to get a triangle. Since a triangle is half a square. Dividing by 2 and multiplying by .5 are the same thing.
Example: 20 x .5 =10 or 20/2 =10

If the simple interest on $1000 for 9 years is $630, then what is the interest rate?
Answers
Answer:
0.07 or 7%
Step-by-step explanation:
I = Prt
630 = (1000)(9)r
630 = 9000r
r = 0.07
Step-by-step explanation:
Simple interest (SI) = $ 630
Time (T) = 9 years
Principal (P) = $ 1000
Rate (R) = ?
We know
[tex]si = \frac{ptr}{100} \\630 = \frac{1000 \times 9 \times r}{100} \\ 630 = 90r \\ r \: = \frac{630}{90} \\ = 7\%[/tex]
Therefore the rate of interest is 7%.

At a flea market, used computer games are sold at the prices shown in the table below.
Number of Games Price ($)
2 9.00

Answers
The proportion relation between the number of games and the price is given by the proportionality constant k = 4.5
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the number of games be represented as x
Let the cost for the total number of games be y
And , the values of x = { 2 , 5 , 7 }
Now , the values of y = { 9.00 , 22.50 , 31.50 }
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
On simplifying , we get
9 = k ( 2 )
Divide by 2 on both sides , we get
k = 4.5
And , 22.50 = k ( 5 )
Divide by 2 on both sides , we get
k = 4.5
Therefore , the proportionality constant is k = 4.5
Hence , the proportion is y = 4.5x
