Answer:
The answer is C.
Step-by-step explanation:
angle 5 and 4 makes a line which is 180 and since angle 5 equals 57 , 180-57=123.
The maximum height occurs at the vertex found using t = -b/2a
Solve for t
t = -20 / 2(-5) = -20/-10 = 2 seconds.
Now replace t with 2 in the original equation to solve for the height:
h(t) = -5t^2 + 20t + 110
h(2) = -5(2)^2 + 20(2) +110
h(2) = -5(4) + 40 + 110
h(2) = -20 + 40 + 110
h(2) = 130
Travis only threw the spike 130 meters. Since Laura is at 135 meters, the spike did not reach her.
Answer:
Mean = $542.00
Median = $546.00
Standard deviation = $25.08
Step-by-step explanation:
Mean
Mean = $542.00
Median
Arrange all numbers in ascending order
486 516 523 523 529 534 538 546 548 551 552 558 566 574 586
Here the number of elements is odd so the middle one is picked.
So, median is $546.00
Standard deviation
∴ Standard deviation is $25.08

Answer:
y = 8x + 12
Step-by-step explanation:
y = (2x + 3)4
Distribute the 4 to the 2x and 3
y = 8x + 12
