Answer
About 112 students eat lunch 4th period
Step-by-step explanation:
250*.45 = 113
112.5 rounded is 112 because there can not be any half students
Answer:
Find x;
tg 45º= x/7
x=7*tg45º
x=7*1=7
Answer= x=7
Find y;
Cos 45º=7/y
y=7/ Cos45º
y=7/(√2/2)=14/√2=14√2/2=7√2
Answer= 7√2≈9.9.

Answer:
1.275
Explanation:
The given equation is:
f(x) = 0.01(2)ˣ
We want to find the rate of change from 2 to 10 which means that we need to find the slope from 2 to 10.
We start by getting the y-values for each of the given x-values:
at x = 2 ..........> y = 0.01(2)² = 0.04 ...........> point is (2, 0.04)
at x = 10 .........> y = 0.01(2)¹⁰ = 10.24 .........> point is (10, 10.24)
Now, we get the slope as follows:
slope =
Hope this helps :)
Answer:
-1
Step-by-step explanation:
4x+9=-3x+2
=> 7x=-7 move all x to left side and numbers to right side by changing + to - or - to +
x=-1
