A customer has a credit card that charges 18% simple interest every year. How much interest will the customer save
by paying off a credit card debt of $5,000 at the end of 1 year instead of at the end of 3 years?
The customer will save interest by paying off a credit debt is $1,800 at the end of 1 year instead of at the end of 3 years
What is simple interest?Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
A customer has a credit card that charges 18% simple interest every year.
The customer saves by paying off a credit card debt of $5,000 at the end of 1 year instead of at the end of 3 years.
Interest for three years will be
[tex]\rm A_3 = \dfrac{PRT}{100}\\\\\\A_3= \dfrac{5000*18*3}{100}\\\\\\A_3= 2700[/tex]
Interest for one year will be
[tex]\rm A_1 = \dfrac{PRT}{100}\\\\\\A_1= \dfrac{5000*18*1}{100}\\\\\\A_1= 900[/tex]
The saved amount will be
A = A₃ - A₁
A = 2700 - 900
A = 1800
The customer will save interest by paying off a credit debt is $1,800 at the end of 1 year instead of at the end of 3 years

will the inequality "7 multiplied by a number is greater than or equal to 21" have an open boundary point or a closed boundary point on the number line?
Answer:
Closed boundary point
Step-by-step explanation:
It says greater than OR equal too and having a closed boundary will indicate that 21 is apart of the inequality also.

Which of the following represent an exponential growth function?
Answer:
[tex]y=3^x[/tex]
Step-by-step explanation:
Exponential Growth Function
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential growth function is expressed as:
[tex]C(t)=C_o\cdot(1+r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the (positive) growth rate, expressed in decimal
Since r is positive, 1+r is greater than 1.
From the available options, only the last two of them correspond to exponential functions according to the definition above.
Note the third option has a base of 1/3 which is not greater than 1. In fact, it corresponds to an exponential decay function.
The last option has a base 3 and corresponds to a value of r=2 which correctly fits with the definition presented above, thus the correct choice is
[tex]\mathbf{y=3^x}[/tex]

Radha takes some flowers in a basket and visits three temples one by one at each Temple she offer one half of the flowers from the basket if she is left with three flowers at the end find the number of flowers she had in the beginning
Answer:
24
Step-by-step explanation:
She visits 3 temples one by one
She offers 1/2 of what she has in the baske
So 1/2 to the first 1/2 of 1/2 to the second =1/4And 1/2 of 1/2 of 1/2 to the third 1/8She is left with 3 flowers
If she gave 1/2 of what she had left to the 3rd, and the other half was 3
Then it means she gave the 3rd 3 flowers
So 3 is 1/8th of what she had at the beginning
Multiply 3*8 and you get 24

Solve for theta to the nearest degree
Step-by-step explanation:
So first thing is to determine which trigonometric ratio we use here. Theta is adjacent to 5 and 8 is the hypotenuse, so we should be using Cosine.
So we set up the equation
cos θ = adj/hype
cos θ = 5/8
θ = [tex]cos^{-1} (5/8)[/tex]
θ=51.3178125...
θ=51°
If the sides of a triangle have the following lengths, find a range of possible values for x.
LM = 6x + 3, MN = 4x - 17, LN = x + 40
Answer:
The range of possible values of x are;
x > 6
Step-by-step explanation:
To form a triangle, the length of two sides must be greater than the third side
Thus;
6x + 3 + 4x-17 > x + 40
6x + 4x-14 > x + 40
10x-14 > x + 40
10x-x > 40 + 14
9x > 54
x > 54/9
x > 6

Which ordered pair is a solution of the equation?
y = -3x-4.
Answer:
B. Only (-3,5)
Step-by-step explanation:
1. Plug in the x values from the answer choices and see if it gives you the y-value in the answer choices.
A. y=-3(-2) - 4
= 6 - 4
y = 2
The ordered pair for answer A is (-2,4) where the y-value is 4. Well, when you plugged in -2 for x you got 2, not 4. So A can't be the right answer.
B. y=-3(-3) - 4
= 9- 4
y = 5
The y-value in this ordered pair (-3,5) is indeed 5, so this answer holds true.
Therefore, the answer is B because it is the only ordered pair that has the correct solution.
Answer: Only (-3,5)

write an equation for the line that passes through the given points (-2,9) And (1 ,-3)
Answer:
Finding slope: y2-y1/x2-x1
3-9/1+2
=-6/2
Divide 2 from both
=-3/1 or -3
Slope= -3
Finding y-intercept= y=mx+b
Choose any point on the line to plug in the x and the y then plug in the slope.
I choose (1,3)
3=-3×1+b
3=-3+b
Add 3 to both sides
6=b
Y-intercept=6
Equation: y=-3x+6
