Answer:
Pat is right
Step-by-step explanation:
first multiply/divide then add/subtract,
Beth: 20 - 15 = 45 => 5 ≠ 45
Pat: 20 - 15 = 5 => 5 = 5
X= 1 so ur multiplying -2 with 1 basically
Alright, so 9^(-1/2) would mean that we have 1/(9^(1/2)). Since 9^(1/2) is the square root of 9 (1/3 would be the cube root, etc.), we have 1/sqrt(9)=1/3. For 3/(1/3), we have (3/1)/(1/3), which is (3/1)*(3/1)=9. Squaring 9, we get the cube root of 81 which is around 4.3
Answer:
Step-by-step explanation:
Since we're given a time at which the height is maximum, we can use a cosine function for the model.
The amplitude is half the difference between the maximum and minimum: (-27 -(-44))/2 = 8.5 cm.
The mean value of the height is the average of the maximum and minimum: (-27 -44)/2 = -35.5 cm.
The period is given as 3 seconds, and the right shift is given as 1.31 seconds.
This gives us enough information to write the function as ...
H(t) = (amplitude)×cos(2π(t -right shift)/period) + (mean height)
H(t) = 8.5cos(2π(t -1.31)/3) -35.5 . . . . cm
Answer:
60m - 36
Step-by-step explanation:
<em>This equation is asking you what is this quantity times 12? So you distribute the 12 (multiply everything in the quantity by 12)/</em>
(5m - 3)12
12 x 5m = 60m
12 x (-3) = -36
60m - 36
