Answer:
3/2
Step-by-step explanation:
f(0) = 3/2 · 2^0
anything raised to the power of zero equals one
f(0) = 3/2 · 1
When the swimmers first arrived at the pool, the temperature of the water was only 72.5 degrees. By the time the first race started, the temperature had gone up 5.6 degrees. What was the temperature of the water when the first race started?
Answer:
The temperature of the water when the first race started was 78.1 degrees
Step-by-step explanation:
Addition
The temperature of the water of a pool was 72.5 degrees when the swimmers first arrived.
By the time when the first race started, the temperature had increased by 5.6 degrees.
To find the temperature at that very moment we have to add 72.5 degrees + 5.6 degrees = 78.1 degrees
The temperature of the water when the first race started was 78.1 degrees
1. The cost of a fish dinner for a restaurant is $7.95. If they sell it for $11.95, what is the percent markup?
2. If the present salary of an employee is $36,500 and they are to receive a 7% raise next year, what will be the new salary?
3. In 1810, the U.S. land size was 1.68 square miles (in millions). In 1850, it was up to 2.94 square miles (in millions). What was the percent increase?
Answer:
39,055
Step-by-step explanation:
so you say 6 over 100 multiplied by $36,500 over 1. then 100 into 36,500 then you get 365. then you say 6 multiplied by 365 and you get 2,555. then you say 2,555 plus 36,500 then you get 39,055
HELP ASAP PLEASE I NEED TO TURN THIS IS IN 3 HOURS
Answer:
The answer is 170 feet
This is how to solve the question
When you are below sea level it means that you are at a negative (in math terms)
So you are 50 feet below sea level and you want to get to a place that is 120 feet high
So you take 50 into account because your starting below sea level then you add 120 for the distance to get up the mountain
120+50= 170

If the slope of a proportional relationship is 3 what is the equation that represents that line
Answer:
y = 3x
Step-by-step explanation:
A proportional function has the equation
y = kx, where k is the constant of proportionality and also the slope of the line.
Answer: y = 3x
The equation that represents the line whose slope of proportional relationship is 3 is; y = 3x.
The slope of the proportional relationship as given is 3.
In essence, slope, m = 3.However, the equation of the line which represents a proportional relationship usually takes the form; y = Mx.
Since, slope, m = 3.
The equation of the line is; y = 3x.

The answer for the equation: 3x + 2 = 2x- 4
Answer:
x = -6
Step-by-step explanation:
1. 3x + 2 = 2x - 4
2. subtract 2x from 3x to get the variables together.
3. New equation is 1x + 2 = -4
4. Subtract 2 from -4 to get the constants together
5. New equation is 1x = -6
6. Divide by 1 on both sides to get the variable alone
7. Your answer is -6

Consider the following two cash flow series of payments: Series A is a geometric series increasing at a rate of 9.5% per year. The initial cash payment at the end of year 1 is $1,000. The payments occur annually for 5 years. Series B is a uniform series with payments of value X occurring annually at the end of years 1 through 5. You must make the payments in either Series A or Series B.
a. Determine the value of X for which these two series are equivalent if your TVOM is i = 9%. $
b. If your TVOM is 8%, would you be indifferent between these two series of payments? Enter the PW for each series to support this choice.
c. If your TVOM is 5%, would you be indifferent between these two series of payments? Enter the PW for each series to support this choice.
Answer:
Step-by-step explanation:
From the given information;
The present value of series A:[tex]=\Big[1000 \times \dfrac{(1.095)^0}{(1.09)^1}\Big]+\Big[1000 \times \dfrac{(1.095)^1}{(1.09)^2}\Big]+...+\Big[1000 \times \dfrac{(1.095)^4}{(1.09)^5}\Big][/tex]
[tex]= 1000 \Big [ \dfrac{1}{1.09}+ \dfrac{1.095}{1.1881}+ \dfrac{1.199}{1.295}+\dfrac{1.313}{1.912}+\dfrac{1.438}{1.539}\Big][/tex]
[tex]= 1000 \Big[ 0.917 + 0.922 + 0.926 + 0.930 + 0.934\Big][/tex]
[tex]= 1000 \times 4.629[/tex]
[tex]= \$4629[/tex]
Thus, the present value of series A is = $4629
Present value of series A = Present value of series B
[tex]The \ value \ of\ X = \dfrac{Present \ value \ of \ series \ B }{\Big [\dfrac{1-(1+r)^{-n}}{r} \Big ]}[/tex]
[tex]The \ value \ of\ X = \dfrac{4629 }{\Big [\dfrac{1-(1+0.09)^{-5}}{0.09} \Big ]}[/tex]
[tex]The \ value \ of\ X =\dfrac{4629 \times 0.09}{1-0.6499}[/tex]
[tex]The \ value \ of\ X =\dfrac{416.61}{0.3501}[/tex]
[tex]The \ value \ of\ X =1189.97[/tex]
Thus, the value of X = $1189.97

[tex]= 1000\Big [ 0.9259 + 0.9839+0.952 + 0.965+0.979\Big ][/tex]
[tex]= 1000 \times 4.76059[/tex]

[tex]= 1189.97 \times \Big [ \dfrac{1 - (1+0.08)^{-5} }{0.08}\Big ][/tex]
[tex]= \dfrac{1189.97}{0.08} \times \Big ( 1 -0.6806\Big )[/tex]
[tex]= 14874.625 \times 0.3194[/tex]

Thus, the present value of series B = $4750

The sum of three and four tenths and a number is six and six tenths.
6.6 is in one box. Below it are 2 boxes. N is in one. 3.4 is in the other.
Explain how to use the bar diagram to solve the problem.
Answer:
So you take 3.4 and subtract from 6.6 which equals 3.2. Then if you add 3.4+3.2= 6.6. Hope this helps.
Step-by-step explanation:
Sorry I am late hope this helps
Sample Response:
Sum means the result of adding two numbers. The bar diagram represents that an unknown number and 3.4 together make 6.6. So 3.4 + what number equals 6.6? The result is 3.4 + 3.2 = 6.6. The sum of 3.4 and 3.2 is 6.6.

There's a proportion relationship between number of shell and their cost
Step-by-step explanation:
The graph is not given.
However, I've added the appropriate graph as an attachment.
From this, point....
I'll show that the cost and number of shells as given in the question are proportional.
Represent cost with y and number of shells with x
x = 2 when y = 0.8
x = 3 when y = 1.2
x = 4 when y = 1.6
Divide each value of y by x to get the constant of proportion (r).
r = y/x
r = 0.8/2 = 0.4
r = 1.2/3 = 0.4
r = 1.6/4 = 0.4
Notice that the values of r remain constant.
Hence, there's a proportion relationship between both
And what this rate represent is that:.the cost of shell changes at a constant rate when the number of shell is changes.

#6: Tell whether the function below is 1 point
linear or exponential.
*
f(x) = -1/4x + 5
Answer:
Linear function
Step-by-step explanation:
Given
[tex]f(x) = -\frac{1}{4}x + 5[/tex]
Required
Linear or Exponential
A linear equation has the form: [tex]f(x) = mx + c[/tex];
An exponential has the form: [tex]f(x) = ab^x[/tex]
By comparing both functions to: [tex]f(x) = -\frac{1}{4}x + 5[/tex]
The linear function is similar to [tex]f(x) = -\frac{1}{4}x + 5[/tex]
Hence, the given function is a linear function.
