Answer:
A
Step-by-step explanation:
A linear function increases/decreases by a certain amount every year. As it changes 1500 over the first 5 years (300 per year) and 3000 over the next 5 (600 per year), this cannot be liner
A quadratic function goes down then up, or vice versa. This consistently goes up, and is therefore not quadratic
A trigonometric function also goes up and down, so it is not trigonometric
Therefore, as an exponential function can keep going up at different rates over time, this is an exponential function
Answer:
y=5x+13 is the answer
Step-by-step explanation:
so you have to use the y=mx+b method
you plug in 3 for y and -2 for x
3=5(-2)+b,
multiply 5 and -2 to get -10
and it should leave you with 3=-10+b
add -10 to both sides, 10 + 3= 13 and 13 is your b (which is your y-intercept)
13=B
Answer:
V=I R
120= I × 20
I = 120÷20
I = 6 A

For the first question;
To calculate the interest accrued from the total amount and compare it from the $300 that is initially paid for the card, there's a need to get 8.75% from $2,348.62. This is possible by multiplying $2,348.62 by 0.0875, which will give a result of $205.50. So it's difference from $300 is $94.50.
For the second question;
Given the interest is $205.50, it needs to be added to the total amount which generates a result of $2554.12. Next, deduct $300 from it for the payment made in the previous month, and divide it by $600. This will result to an answer of 3.76 - the number of months to pay off the debt.
Answer:
13 inches
Step-by-step explanation:
Let P(t) and P(s) be the perimeters of the equilateral triangle and square respectively. Similarly, t and s be the side lengths of equilateral triangle and square respectively.
According to the first condition :
(Perimeter of an equilateral triangle is 11 inches more than the perimeter of a square)
According to the second condition :
(The side of the triangle is 6 inches longer than the side of the square)
From equations (1) & (2)
3(s + 6) = 4s + 11
3s + 18 = 4s + 11
3s - 4s = 11 - 18
-s = - 7
s = 7 inches
Thus the side of the triangle is 13 inches long.
