Arianna invests $5700 in a new savings account which earns 5.2 % annual interest, compounded monthly. What will be the value of her
investment after 3 years? Round to the nearest cent.
Answers
The amount will be $6660 after 3 years. It can be solved by the cocept of the compound interest.
What is compound interest?
In compound interest, the interest is added in the principal amount after the end of each term. The value after addition the interest is considered as the principal amount for the next term.
The annual interest is 5.2% hence, monthaly interest will be 5.2\12%
Apply the formula of conpound interest.
[tex]A=P(1+\frac{r}{100})^t[/tex]
Here, A is the total amount after the end of time period t, P is the initial amount, and r is the rate of intrest at which the amount is compounded.
Substitute $5700 for P, 5.2/12% for r and 36 for t. Here t is 36 becasue the amount compounded monthly and there are 36 months in a year.
[tex]A=\$ 5700(1+\frac{5.2/12}{100})^{36}\\= \$ 6660[/tex]
Hence, the amount will be $6660 after 3 years. It can be solved by the cocept of the compound interest.

A population of lizards in a large region doubles every year. The number of lizards can be
modeled by the equation y = 500 * 2 ^ x where
× is the number of vears after a researcher
measures the population size . When x = - 3
-3what does the value of y represent ?
Answers
The value of y when x = -3 represents that the population of the lizard three years before the researcher measures the population size is 63
How to interpret the function at x = -3?From the question, we have the following parameters that can be used in our computation:
y = 500 * 2 ^ x
The above equation is an exponential function
Such that
x is the number of years after a researcher measures the population size
When x = -3, we have the equation to be
y = 500 * 2^-3
Evaluate the product
y = 62.5
Approximate
y = 63
This means that the value of y at x = -3 is 63

There was a car behind her for one-half of that time. How far did Zoe ride while the car was behind her?
Write your answer as a whole number.
Answers
The distance that Zoe rode while the car was behind her was of:
160 kilometers.
How to obtain the distance?The relation between velocity, distance and time is that the velocity is the distance divided by time, hence the equation is presented as follows:
v = d/t.
The values of the parameters in this problem are given as follows:
Velocity of v = 80 km/h.Time of t = 4 h.(both of these measures are taken from the first sentence of the problem).
Then the total distance is obtained replacing the values into the equation as follows:
80 = d/4
d = 80 x 4
d = 320 kilometers.
The car was behind her for half the trip, hence the distance that the car spent behind her was of:
d = 0.5 x 320 = 160 kilometers.

the number of devices a particular manufacturing company can produce is a function of the number of hours spent making the devices. On average, 4 devices are produced each hour. Assume that devices are produced at a constant rate. Write an equation in two variable that describes the number y, as a function of time the company sends making the devices x
Answers
Answer: y = 4x
Step-by-step explanation: The number of devices a company can produce is a function of the number of hours spent making the devices. On average, 4 devices are produced each hour. If we let x represent the number of hours spent making the devices and y represent the number of devices produced, we can write an equation to describe this relationship as follows:
y = 4x
This equation states that the number of devices produced is equal to 4 times the number of hours spent making the devices. For example, if the company spends 10 hours making the devices, the number of devices produced will be 4 * 10 = 40.
Therefore, the equation y = 4x describes the number of devices produced by the company as a function of the number of hours spent making the devices.
19. MODELING In Example 6, 44% of the voters say they plan to reelect the mayor. The poll has a margin of error of ±3% percentage points. Use a model to write and solve an absolute value inequality to find the least and greatest percents of voters who plan to reelect the mayor.
Answers
The absolute value inequality to find the percentages is given as follows:
|P - 44| ≤ 3.
Then the percentages are given as follows:
Least: 41%.Greatest: 47%.What is the absolute value inequality?The estimate of the percentage is of:
44%.
The margin of error is of:
±3%.
Both the estimate and the margin of error are taken from the problem.
This means that the absolute difference between the percentage P and the estimate of 44% is of at most the margin of error of 3%, hence the inequality is given as follows:
|P - 44| ≤ 3.
The absolute difference means that the difference can be either positive or negative.
Then the lowest percentage is obtained when:
P - 44 = -3
P = -3 + 44
P = 41.
The highest percentage is obtained when:
P - 44 = 3
P = 3 + 44
P = 47.

In this problem we find the case of a triangle, in which the length of two sides are known and we need to determine the range of costs associated to the set of all possible triangles. This can be derived by the geometric system described in the image attached below. The minimum and the maximum costs of the pendant:

l = 10.5 cm - 2.5 cm
l = 8 cm
s = 10.5 cm + 8 cm + 2.5 cm

Answers
The rocket reaches its maximum height at 2.25 second(s) after launch
The maximum height reached by the object is 88 feet.
What is the maximum height the rocket reached?Given function:
h(t) = -16t² + 72t + 7
By differentiating the function, we have
h'(t) = -32t + 72
Set the function to 0
-32t + 72 = 0
32t = 72
Divide both sides by 32
t = 2.25
Hence, the time is 2.25 seconds
To find the maximum height reached by the rocket,
Substitute t = 2.25 into
h(t) = -16t² + 72t + 7
h(2.25) = -16(2.25)² + 72(2.25) + 7
= -16(5.0625) + 162 + 7
= -81 + 162 + 7
h(2.25) = 88
