Answer:
3.61 seconds
Step-by-step explanation:
The bird starts 50 feet in the air, so will come down to a height of 40 feet after 3.61 seconds.
We want to solve h = 40.
40 = -16t^2 +55t +50
16t^2 -55t -10 = 0
t = (55 +√(55^2 -4(16)(-10)))/(2(16)) = (55 + √3665)/32 ≈ 3.61060
The bird will be 40 ft above the ground the first time after about 3.61 seconds.
The range of the function 8x + y = -3 at the domain {−3, 1, 2, 4} is {21, -11, -19, -35}
<h3>How to determine the range of the function?</h3>
From the question, we have the following equation that can be used in our computation:
8x + y = -3
Start by making the variable y the subject of the formula
So, we have
y = -8x - 3
Using the domain = {−3, 1, 2, 4} the values in the range are calculated as follows
y = -8 x -3 - 3 = 21
y = -8 x 1 - 3 = -11
y = -8 x 2 - 3 = -19
y = -8 x 4 - 3 = -35
When these values are combined, we have the notation to be:
{21, -11, -19, -35}
So, the range is {21, -11, -19, -35}
