Which graph represents y as a function of x?
Answer:
b
Step-by-step explanation:
=======================================================
Explanation:
Graph B, C and D all fail the vertical line test. If it's possible to pass a vertical line through more than one point on the curve, then it's said to have failed the vertical line test. Any vertical line itself therefore is automatically not a function. If a graph fails the vertical line test, then it is not a function.
A function is only possible if for any given input x, we have exactly one and only one output. For graph A, the output is the same value regardless of the input. This is a constant function.
For something like graph B, the input x = 0 produces three different y outputs. The output y = 0 is one of those, and the others are off the screen so it's hard to tell what they are. Turns out it doesn't matter and all we need to do is the vertical line test. Graphs C and D are a similar story. In the case of graph D, the only input x allowed is x = 2 and it produces infinitely many y outputs.

Which of the following graphs represents the equation below?
Andy estimated that he would need 73 feet of lumber for a tree house project. He later found that the actual amount of lumber needed was 62 feet. What was the percent error of Andy's estimation?
Answer:
17.74%
Step-by-step explanation:
The formula for percent error is given as:
|Estimated value - Actual value|/Actual value × 100
From the above question:
Estimated value = 73 feet
Actual value = 62 feet
Hence,
Percent error = |73 - 62|/62 × 100
= 11/62 × 100
= 17.741935484%
Approximately , percent error = 17.74%
Therefore, the percent error of Andy's estimation is 17.74%

From a barrel of colored marbles, you randomly select 1 blue 6 yellow 7 red 4 green and 6 purple marbles
Complete question :
From a barrel of colored marbles, you randomly select 1 blue 6 yellow 7 red 4 green and 6 purple marbles. Find the experimental probability of randomly selecting a marble that is NOT yellow.
Answer:
Step-by-step explanation:
Total number of marbles :
Blue = 1 ; yellow = 6 ; red = 7 ; green = 4 ; purple = 6
Total = (1 + 6 + 7 + 4 + 6) = 24 marbles
Probability of selecting marble that is not yellow :
Number of marbles that aren't yellow / total number of marbles
Marbles that aren't yellow = 24 - 6 = 18
P(selecting a marble that isn't yellow) = 18 / 24 = 3/4

Which ordered pairs are solutions to y = x + 1?
A (0,1),(1,2), (2,3)
B (0, -1), (2, -1), (3,-2)
C (0,1),(1,2), (2, 4)
D (0,1),(2, 1), (3, 1)
Answer:
A. ( 0, 1 ), ( 1, 2 ), ( 2, 3 )
Step-by-step explanation:
( x, y ) = ( 0, 1 )
Here,
x = 0
y = 1
y = x + 1
1 = 0 + 1
1 = 1
( x, y ) = ( 1, 2 )
Here,
x = 1
y = 2
y = x + 1
2 = 1 + 1
2 = 2
( x, y ) = ( 2, 3 )
Here,
x = 2
y = 3
y = x + 1
3 = 2 + 1
3 = 3

Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
5x - (4 • 4) 5x - 16

In 1990, the population of the U.S. was about 250 million and was growing exponentially
at a rate of about 1% per year. At this rate, in what year will the population have
doubled?
a. 2080
b. 2070
c. 2060
d. 2050
Answer:
The correct answer is C.
Step-by-step explanation:
Giving the following information:
Present Value (PV)= 250 million
Future Value (FV)= 500 million
Growth rate (g)= 1% per year
First, we need to calculate the number of years required for the population to double:
n= ln(FV/PV) / ln(1+g)
n= ln(500/250) / ln(1.01)
n= 69.66 = 70 years
It will take 70 years for the population to double.

Answer:
B. y = 85x
Step-by-step explanation:
First, find the rate of change of the graph:
Rate of change = change in y/change in x
Using two points (0, 0) and (4, 300),
Rate of change (m) = (300 - 0)/(4 - 0) = 300/4
Rate of change (m) = 75
Compare this with the rate of change of the given equations in the options.
✔️Option A: y = 65x + 100
The rate of change of this equation is 65, which is less than the rate of change of the given graph (75)
✔️Option B: y = 85x
The rate of change of this equation is 85, which is greater than the rate of change of the given graph (75)
✔️Option B: y = 50x + 150
The rate of change of this equation is 50, which is less than the rate of change of the given graph (75)
✅Therefore, the equation that has a greater rate of change than the one shown in the graph is y = 85x

Solve the triangle for all missing sides and angles
Answer:
x = 35
C = 18.92
A = 71.07
Step-by-step explanation:
x)
Use the Pythagorean theorem to find the unknown side.
[tex]a^{2} +b^{2} =c^{2} \\\\\\12^{2} +x^{2} =37^{2} \\x^{2} = 37^{2}-12^{2}\\x=35[/tex]
For Angle C
The angle C can be found using the inverse sine function.
C=arcsin(opp/hyp)
C=arcsin(12/37)
C=18.92
For Angle A
The sum of all the angles in a triangle is 180 degrees.
A + 90 + 18.92 = 180
A = 71.07
