4.051 rounded to the nearest hundredth is 4.05 because you rounded down from 1.
Point slope form is
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line.
Plugging in the given values:-
y - 1.4 = 1.8(x - (-4.5))
y - 1.4 = 1.8(x + 4.5) So the correct choice is A.
If sinα=cosß it means that ß=90-α. This also means that α+ß=90 so we can say:
4k-22+6k-13=90
10k-35=90
10k=125
k=12.5°
...
The above identity comes up a lot, and is one worth committing to memory for sure.
sinα=cos(90-α) or vice versa cosα=sin(90-α)
The first 1 is multiply by 1/2
Answer:
$1,875
Step-by-step explanation:
(if 500 is 80%, divide 1500 by 4 to get 20%)
1500 divided by 4 is 375
375 plus 1500 is 1875
