for P(t) = 65- 5t
domain is [0, 13]
because intially at t = 0 total puppy available is 65 (put t = 0 in equation)
now after 13 days
P(t) = 65 - 5×13 = 65-65 = 0
no puppy available. so t has last range of 13.
similarly for second its domain is [0, ∞]
as subscribers will increase as t will increase.
for 3rd
C(t) = 65 + 5t
here t is guest so . they can only accomdate 30 guests only so t csn go to 30 only.
so domain is [0,30]
I am not seeing an equation or a picture but I’ll give you the definition:
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
It’s not a function because when it’s graphed put it doesn’t pass the vertical line test
Substitute in what you already know into the formula, since the formula is (a=bh) you already know what A is so now you have 50=bh, now the length is x+7 , length is basically height , so h in the formula , so now you get 50=b(x+7) , now you need b luckily you already have b, so plug in 50=(x+2)(x+7) , you can guess and check or you can solve for x by double distributing
140 tests is ___% of 160 tests.
140/160
140 ÷ 160 = 0.875
0.875 × 100 = 87.5
87.5%
140 tests is 87.5% of 160 tests.
