Answer:
Only option C is correct, i.e. The input, or independent variable, is years in operation.
Step-by-step explanation:
Given is the scatter plot of Years in Operation vs. Enrollment at Daycare Center.
The input is always independent variable and is plotted along x-axis.
The output is always dependent variable and is plotted along y-axis.
From the graph, it is clearly visible that:-
x-axis: Years in Operation.
y-axis: Enrollment at Daycare Center.
It means <u>"The input, or independent variable, is years in operation."</u>
Hence, only option C is correct, i.e. The input, or independent variable, is years in operation.
S < 20 , -5x > -100 , etc
Answer:
200 feet
Step-by-step explanation:
I believe you can use cosine 60° (which is 0.5) and set it equal to x/400
.5 = <u> x </u>
400
x = 200
Answer:
100√65 yds
Step-by-step explanation:
The Pythagorean Theorem is a^2+b^2=c^2. In this case a=700, b=400, and c is the unknown.
- 700^2+400^2=c^2
- 490000+160000=c^2
- 650000=c^2
- c=√650000
√650000=√(100^2•65)=100√65
Answer:
1) 4, 7, 12 and 19
Tenth term = 103
2) 2, 8, 18, 32
Tenth term =200
Step-by-step explanation:
Given the nth term of the sequence
1) f(n)= n²+3
When n = 1
f(1) = 1²+3
f(1) = 4
When n = 2
f(2) = 2²+3
f(2) =4+3
f(2) = 7
When n = 3
f(3) = 3²+3
f(3) = 9+3
f(3)=12
When n =4
f(4) = 4²+3
f(4) = 16+3
f(4) = 19
The first four terms are 4, 7, 12 and 19
f(10)= 10²+3
f(10) = 103
Tenth term is 103
2) f(n) = 2n²
When n = 1
f(1) = 2(1)²
f(1) = 2
When n = 2
f(2) = 2(2)²
f(2) = 2(4)
f(2) = 8
When n= 3
f(3)= 2(3)²
f(3) = 2(9)
f(3) = 18
When n= 4
f(4) = 2(4)²
f(4) = 2(16)
f(4) =32
The first four terms are 2, 8, 18, 32
f(10) = 2(10)²
f(10) =2(100)
f(20) = 200
The tenth term is 200
