Porsha calculates the amount of money she will have at the end of 6 years on a $5,000 investment earning 3.75% interest compounded quarterly. She writes the following expression:5,000(1+0.0375)

Answers

Answer:

It is B. Porsha's expression should have 1 + 0.009375 in the parentheses.

Step-by-step explanation:

I got it in the test

The formula for annual compound interest is A = P (1 + r/n) ^ nt:

Where:

A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested or borrowed for

A = P (1 + r/n) ^ nt

A= 5000(1+0.0375/4)^4*6

A= 5000(1+0.0375/4)^24

A=$6255.05 (future Value)

Tabitha wants to hang a painting in a gallery. The painting and frame must have an area of 58 square feet. The painting is 7 feet wide by 8 feet long. Which quadratic equation can be used to determine the thickness of the frame, x?

Answers

The quadratic equation would be;
x2+15x-2=0

Working:
Assuming the area around the painting i.e the frame, has a uniform thickness, then;
Length of painting and frame = 8+x
Breadth of painting and frame= 7+x

The area from above step gives;
A= LxW
A= (8+x)(7+x)
On expanding, 56+8x+7x+x2
On simplifying,
56+15x+x2. This should be equal to 58.
58=x2+15x+56
Taking 58 to the other side,
x2+15x-2=0

How can you use addition and subtract to put together and separate measures of an angle and its parts

Answers

How can you use addition and subtract to put together and separate measures of an angle and its parts

Adding and Subtracting angles can be put this way.
Complementary angles can be formed by two angles with total of 90 degrees.
Supplementary angles can be formed by two angles with total of 180 degrees.

X + Y = 90 degrees
Y = 90 - X
X = 90 - Y

X + Y = 180 degrees
Y = 180 - X
X = 180 - Y

What is the answer and work too the equation 4x+9+3x=30

Answers

rearrange the like terms first.
1. 4x+3x+9=30

add the like terms
2. 7x+9=30

move the 9 to the other side.
3. 7x=30-9

subtract them
4. 7x=21

divide bothers sides by 7
5.
$(7x = 21)/(7)$

which it will end with the result of
x=3

The functions f(x) and g(x) are shown below:f(x) = 0.05x
g(x) = (0.05)x
Which statement best describes the graph of f(x) and g(x)?

Answers

f(x) and g(x) are two functions each representing data points. We can see from the given function both of the functions are equal because both have a value of 0.05x. If you evaluate the equation with a given x value, we will observe that the answer for both functions is the same.

This is the best answer that I can give you. The graphs will both have their y-intercept equal to 0.05
