Answer:
? = 49
Step-by-step explanation:
To solve this we just need to understand that when A=1, B=7. So when the side for a is 7 that is basically multiplying A by 7 so we have to do the same to the B side. So when the B side is multiplied by 7 it would be 7*7 =49 so the ? is equal to 49 when that similar side is equal to 7.
This is all based on the fact that the two triangles must be similar triangles.
we can draw the graph of cosine with amplitude 2.
Step-by-step explanation:
In the given function g(x) = 2cosx we know the following parameters which are helpful to draw the graph.
Its a cosine graph given in the form of y = acos(Bx + c) + d
Here a is amplitude, period = , c = phase shift, d = vertical shift
We know a = 2, B = , c = 0, d = 0.
Answer: $19
Step-by-step explanation:
The total cost in dollars to rent a life Jacket and share a kayak for h hours is given by
for h= 3 hours, the total cost is
applying BODMAS
Answer:
5x=2x−4−2
Subtract 2 from −4 to get −6.
5x=2x−6
Subtract 2x from both sides.
5x−2x=−6
Combine 5x and −2x to get 3x.
3x=−6
Divide both sides by 3.
x= -6/3
Divide −6 by 3 to get −2.
x=−2
