Given:
The given equation is
[tex]60=5(1.07)^x[/tex]
To find:
The initial value and growth/decay factor.
Solution:
The general exponential growth/decay model is
[tex]y=a(1+r)^x[/tex] ...(i)
where, a is initial value, if r>0, then |r| is growth factor, if r<0, then |r| is decay factor and x is time.
We have,
[tex]60=5(1.07)^x[/tex]
It can be written as
[tex]60=5(1+0.07)^x[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]a=5\text{ and }r=0.07[/tex]
Here, initial value is 5 and growth factor is 0.07, i.e., 7%.
Therefore, the correct option for first question is d and correct option for second question is a.

what is the specified term of 3 6 12 find a7
Answer:
a₇ = 192
Step-by-step explanation:
There is a common ratio r between consecutive terms in the sequence.
r = 6 ÷ 3 = 12 ÷ 6 = 2
This indicates the sequence is geometric with n th term
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 3 and r = 2 , thus
a₇ = 3 × [tex]2^{6}[/tex] = 3 × 64 = 192

In the figure below, m 1 = 3x° and m2 = (x+36).
Find the angle measures
Answer:
Step-by-step explanation:
∠1+∠2=180°
3x+x+36=180
4x=180-36=144
x=144/4=36°
∠1=3x=3×36=108°
∠2=x+36=36+36=72°
The measures of the angles are m∠1 = 108° and m∠2 = 72°.
Given,
m∠1 = 3x°
m∠2 = (x + 36)°
We need to find the measure of these angles.
What is a straight line angle?The straight line angle is 180 degrees.
If the angle is split the sum must be equal to 180 degrees.
We have,
m∠1 = 3x°
m∠2 = (x + 36)°
The figure is at a straight-line angle.
So we have,
m∠1 + m∠2 = 180°
3x° + (x + 36)° = 180
3x + x + 36 = 180
4x + 36 = 180
4x = 180 - 36
4x = 144
x = 144/4
x = 36
Now,
- m∠1
= 3x
= 3 x 36
= 108
- m∠2
= x + 36
= 36 + 36
= 72
Thus the measures of the angles are m∠1 = 108° and m∠2 = 72°.

On a piece of paper graph f(x) =6 • (0.4)^x. Then determine which answer choice matches the graph you drew
Answer:
The general form of an exponential function is
.... (1)
Where, a is initial value and b is growth or decay factor.
If b>1, then it is an increasing function and if 0<b<1, then it is a decreasing function.
The given function is
.... (2)
From (1) and (2) it is clear that
The value of a is 6. It means the initial value or y-intercept of the function is 6.
The value of b is 0.4, which is less than 1. It means the function is a decreasing function.
Let x be the following values: 1, 2, 3, 4 , 5.
Let f(x) = y.
I will do one only.
Let x = 1
y = 6•(0.4)^(1)
y = 6•(0.4)
y = 2.4
Your first point is (1, 2.4).
Do the rest in like manner. Then graph each point on the xy-plane and lastly connect each point with a smooth curve.

In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8.
Many pundits claim that the worst is yet to come, with an earthquake 142,990 times
as intense as the 1906 earthquake ready to hit San Francisco. If the pundits ability
to predict such earthquakes were correct, what would be the magnitude of their
claimed earthquake? Round your answer to the nearest tenth.
Answer:
1115322
Step-by-step explanation:
In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8.
Claimed statement is he worst is yet to come, with an earthquake 142,990 times as intense as the 1906 earthquake ready to hit San Francisco.
We need to find the magnitude of their claimed earthquake.
It can be calculated by simply multiplying 142,990 by 7.8 as follows :
[tex]E=142990 \times 7.8\\\\=1115322[/tex]
The magnitude of claimed earthquake is 1115322 .
Using the earthquake intensity relation on the Ritcher scale, the magnitude of the claimed earthquake would be 13.0
Uisng the relation :
[tex] M_{a} - M_{b} = log(\frac{I_{a}}{I_{b}}) [/tex] Mb = 7.8Intensity = 142990Substituting the values into the equation :
[tex] M_{a} - 7.8 = log(142990) [/tex]
[tex] M_{a} - 7.8 = 5.1553056 [/tex]
[tex] M_{a}= 5.1553056 + 7.8 [/tex]
[tex] M_{a} = 12.955 [/tex]
Therefore, the magnitude of the claimed earthquake would be 13.0

A mathematical model that estimates the average atmospheric concentration of carbon dioxide, C, in parts per million, x years after 1950 is
Answer:
C = 306 +1.3x
Step-by-step explanation:
In 1950 the average atmospheric concentration of carbon dioxide was 306 parts per million with an estimated increase of 1.3 parts per million every single year. Therefore we can use these numbers to create the following mathematical model.
C = 306 +1.3x
This model multiplies the number of years after 1950 (x) by the estimated carbon dioxide increase per year in parts per million, and finally adds the initial atmospheric concentration of carbon dioxide from 1950 to calculate the current atmospheric concentration of carbon dioxide

Intercepts of a Line
The x-intercept of a given line is the point where the line crosses the x-axis and the y-intercept of a given line is the point where the line crosses the y-axis.
We are given the following line:
-12x + 18y = 108
To find the x-intercept, we set y=0 and solve for x:
-12x + 18*0 = 108
-12x = 108
x = 108 / (-12) = -9
The x-intercept is the point (-9,0)
To find the y-intercept, we set x=0 and solve for y:
-12*0 + 18y = 108
18y = 108
y = 108 / 18 = 6
The y-intercept is the point (0,6)
