Is the following conditional true?<br> If a number is divisible by 2, then it is divisible by 4.

Gennadij [26K]

No the conditional is not true. The converse of the conditional would be true. If a number is divisible by 2, it wouldn’t necessarily be divisible by 4, but if a number is divisible by 4, it’s divisible by 2.

Given:
h(t) = 25 - a·t²
h(0.5) = 21

Find:
t such that h(t) = 0

Solution:
h(0.5) = 25 - a·0.5² = 21
25 - 21 = a/4
4·4 = a = 16
Then
h(t) = 25 - 16t²
We want h(t) = 0, so
0 = 25 - 16t²
16t² = 25
t² = 25/16 = (5/4)²
t = 5/4 = 1.25

It takes 1.25 seconds for the entire 25 ft drop.

Write an equation for a line that is parallel to the graph of y = -3x + 6 and passes through the point at (-4, 7)

ale4655 [162]

Y = -3x + 6....the slope here is -3. A parallel line will have the same slope.

y = mx + b
slope(m) = -3
(-4,7)....x = -4 and y = 7
now we sub into the formula and find b, the y int
7 = -3(-4) + b
7 = 12 + b
7 - 12 = b
-5 = b
so ur parallel equation is : y = -3x - 5 <==
