Answer:
Length: 80 feet
Width: 36 feet
Step-by-step explanation:
232/2 = 116
116-36 = 80
(i.e. 80+80+36+36=232)
Answer:
1.95secs
Step-by-step explanation:
Given the height of the float expressed as h(t) = -16t2 - 3t + 55.
The floats reach the swimmer at h(t) = 0
Substitute
0 = -16t^2 - 3t + 55.
16t^2 + 3t - 55 = 0
Using the general formula;
t = -3±√3²-4(16)(-55)/2(16)
t = 3±√9+3520/32
t = 3±√3529/32
t = 3+59.41/32
t = 62.41/32
t = 1.95
Hence it will take 1.95secs
Answer:
The correct option is A). $112295.05
Step-by-step explanation:
The equation for approximating the total cost is given to be :
y = 1.55x + 110419 , where x is the annual household's income and y is the total cost in dollars of raising a child in the united states from birth to 17 years
We need to calculate the total cost of raising a child in the united states from birth to 17 years if the annual household's income is given to be $1211
So, for this we will use the given equation and substitute x = 1211 and find the value of y which will be our total cost
⇒ Total cost , y = 1.55 × 1211 + 110419
⇒ y = 1877.05 + 110419
⇒ y = 112296.05 ≈ 112295.05
Hence, The approximate total cost of raising a child from birth to 17 years in a household with a weekly income of $1211 = $112295.05
Therefore, The correct option is A). $112295.05
Answer:
B = (7, 2)
Step-by-step explanation:
B = 2M -A
B = 2(3, 4) -(-1, 6) = (2·3-(-1), 2·4-6)
B = (7, 2)
_____
The expression for the other end point, B, comes from the equation for the midpoint.
M = (A +B)/2
2M = A + B . . . . . multiply by 2
2M -A = B . . . . . . subtract A to get an expression for B
