Answer:
x just represents a number
Answer:
Step-by-step explanation:
radius =( (8+7)^2 + (7+1)^2 )^1/2 = 17 unit
Equation of the circle = (x + 7)^2 + (y+1)^2 = 17^2
= (-15+7)^2 + (y+1)^2 = 17^2
=14
(-15, 14) lies on this circle
You move the decimal four spaces to the left
Answer:
43.2 grams
Step-by-step explanation:
A = P (1 + r)^t
where A is the final amount,
P is the initial amount,
r is the rate of growth or decay,
and t is time.
Given:
P = 570
r = -0.18
t = 13
A = 570 (1 − 0.18)^13
A = 43.2
Answer:
$32 is the sales price.
Step-by-step explanation:
First, change the percentage to a decimal.
60% = 60/100 = 0.6
Next, multiply 0.6 with the regular price ($80)
80 x 0.6 = 48
$48 is the discount. Subtract from the original price
80 - 48 = 32
$32 is the sales price.
