Oh yeah I have to do that and I’m gonna be
Answer:
Step-by-step explanation:
you know ; for all reals a ; cos(π/2 - a) = sin(a)
so : sin(5x+15) = cos(π/2-(5x+15) ) = cos(π/2-5x-15)
sin(5x+15)=cos(4x−6) eqivaut : cos(π/2-5x-15) = cos(4x−6)
note : cos(a)=cos(b) : a= b +2kπ or a= - b +2kπ ....k in Z
π/2-5x-15 = 4x−6 + 2kπ or π/2-5x-15 = - (4x−6) + 2kπ....k in Z
continue calculate : x .......
Answer:
<u>180 miles</u>
Step-by-step explanation:
- Ann's car can go 288 miles on 8 gallons
<u>Base rate</u>
- = No. of miles / No. of gallons
- = 288 / 8
- ⇒ 36 miles per gallon [Important to rememeber!]
<u>5 gallons</u>
- Distance for 5 gallons = base rate x 5
- Distance = 36 x 5
- Distance = <u>180 miles</u>
Answer: (-28/3 , -2/3)
Step-by-step explanation: Given the
coordinates of the point on the directed line segment from (−6,−6) to (-4, 10)
(X2 -X1) , (Y2 - Y1)
(-4-6) , (10- - 6)
-10, 16
To partitions the segment into a ratio of 1 to 3?
-10×1/3 , 16×1/3
-10/3 , 16/3
The answer will be
(- 6 - 10/3) , (-6 +16/3)
(-28/3 , -2/3)
