Answer:
Part A = 3 years
Part B = $3400
Step-by-step explanation:
To find this, we can model the value of the computer as V = A(.5)^x, in which x is the number of years. To find how long it takes to get to 12.5%, we can ignore all but the exponential part of the function and set equal to the percentage.
.125 = (.5)^x
3 = x
To find the initial value of the computer, use the formula created and solve for A.
V = A(.5)^x
425 = A(.5)^3
425 = A(.125)
3400 = A

Answer:
(- 6, 6 )
Step-by-step explanation:
Assuming the centre of dilatation is the origin, then
The coordinates of the image points are 3 times the original points
B = (- 2, 2 ), then
B' = ( 3 × - 2, 3 × 2 ) = (- 6, 6 )
Answer:
x=36
Step-by-step explanation:
First rewrite equation then multiply each side by 36. 9x-36=4x+144.
then move the variable 9x-4x+36=144. Next subtract 9x and 4x ...5x=144+36.... 5x=180. Lastly you divide 180÷5 this your answer x=36
Answer:
ans: 31°
Step-by-step explanation:
<EFG = <EFH + <HFG
2x+52= 21 + ( x+31)
2x-x= 21 +31 -52
x= 0
so our question is to find <HFG so,
x+31°= 31°
