Answer:
It is(-1,5)
Step-by-step explanation:
You just divide the (-3,15) by 3 and you get your answer.
For each Y value to have more than one x value would be a linear function.
It would make a straight line.
Answer:
43.17 ft/s
Step-by-step explanation:
Let the height of the wall is y.
distance of wall from light is 20 feet.
y = 20 tanθ .... (1)
time period, T = 3 second
Differentiate equation (1) with respect to t.
dy/dt = 20 x 2.16
dy/dt = 43.17 ft/s
Answer:
450 feet at ground level
Step-by-step explanation:
The width of the bridge at ground level will be where the function intercepts the x-axis also known as the roots or zeros of the function. They are found using the zero product property to set each factor equal to 0.
This means (x-225) = 0 and (x + 225) = 0. So x = -225, 225.
This means the width is the absolute value of |-225| + 225 since distance cannot be negative. This makes it 450 feet.
Answer:
The experimental probability of the coin landing tails-side up is <u>60</u><u>%</u><u>.</u>
Step-by-step explanation:
The probability of it landing heads up is 4/10. You can use 4/10 to find how many times it landed on tails.
10/10 - 4/10= 6/10 now convert 6/10 into a percentage, 60/100=<u>60%</u>
