Marsha Deposited $5,500 into a savings account 5 years ago. The simple interest rate is 2%. How much money did Marsha earn in in
Naily [24]

Answer: $550.00

Step-by-step explanation: Equation: I = Prt

<u>Calculation:</u>

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year,

then, solving our equation

I = 5500 × 0.02 × 5 = 550

I = $ 550.00

The simple interest accumulated

on a principal of $ 5,500.00

at a rate of 2% per year

for 5 years is $ 550.00.

Hope this helped! ;)

Solve each component inequality and graph the solution
lord [1]

Solution: The value of x after solving both components is 2 or (2,11].

Explanation:

From the first component it is clearly noticed that the value of x is greater than 2.

Simplify the second component.

x-1\leq 10\\x\leq 11

From the above inequality it is clearly noticed that the value of x is less than or equal to  11.

Solving both components we get 2 and the graphical representation is shown in the figure.

The red portion shows the solutions of x>2, blue portion shows the solution of x-1\leq 10 and purple portion which combination of red and blue portion shows the solution of both inequalities.

Therefore, value of x after solving both components is 2 or (2,11].

Type the correct answer in each box.

The inverse of the function are respectively; f⁻¹(3) = 2 and f⁻¹(8) = 8.5

<h3>How to find the inverse of a Function?</h3>

The formula to find the equation of this function using two coordinates is;

(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1)

Using the first 2 coordinates, we have;

(y - 1)/(x + 1) = (3 - 1)/(2 + 1)

(y - 1)/(x + 1) = 2/3

3y - 3 = 2x + 2

3y = 2x + 5

y = ¹/₃(2x + 5)

Thus, the inverse is;

f⁻¹(x) = (3x - 5)/2

Thus;

f⁻¹(3) = (3*3 - 5)/2

f⁻¹(3) = 2

Similarly;

f⁻¹(x) = (3x - 5)/2

Thus;

f⁻¹(8) = (3*8 - 5)/2

f⁻¹(8) = 8.5

Transforme em π rad :<br>a)30°<br>b)40°<br>c)45°<br>d) 50°
Roman55 [17]

Answers:

a) \frac{1}{6} \pi rad

b) \frac{2}{9} \pi rad

c) \frac{1}{4} \pi rad

d) \frac{5}{18} \pi rad

Step-by-step explanation:

In this case we are dealing with angles, which can be expressed in degrees (\°) or radians (rad).

Now, before making the conversions we have to know the equivalence between degrees and radians:

180 \°=1 \pi rad

Taking this information into account, let's begin with the answers:

a) 30\° \frac{1 \pi rad}{180 \°}=\frac{1}{6} \pi rad

b) 40\° \frac{1 \pi rad}{180 \°}=\frac{2}{9} \pi rad

c) 40\° \frac{1 \pi rad}{180 \°}=\frac{1}{4} \pi rad

d) 50\° \frac{1 \pi rad}{180 \°}=\frac{5}{18} \pi rad
