Suppose f(x) = x2 and g(x) = 5x2. Which statement best compares the graph of g(x) with the graph of f(x)?
A.
The graph of g(x) is the graph of f(x) horizontally stretched by a factor of 5.
B.
The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5.
C.
The graph of g(x) is the graph of f(x) vertically compressed by a factor of 5.
D.
The graph of g(x) is the graph of f(x) shifted 5 units right.
Answer:
B. The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5
Step-by-step explanation:
It is a quadratic and in the form:
f(x) = a(x-h)^2 + k
In this case a = 5, and if a is greater than 1, then the parabola is vertically stretched. It is not vertically compressed because a is not less than 1.
h and k are irrelevant because there are no horizontal or vertical shifts in the graph.
Therefore, when compared to f(x) = x^2, the graph has only been vertically stretched by a factor of 5.
Answer:
the graph of g(x) is the graph of f(x) vertically stretched by a factor of 5

A town got 2.76 inches of rain during a rainstorm write this number in expanded form
Answer: 2 + 0.7 + 0.06
Step-by-step explanation:
Expanded form is a method of writing numbers in such a way that the mathematics value of their individual digits would be shown.
Therefore, 2.76 inches in expanded form would be:
= 2 + 0.7 + 0.06
The above shows the units value, tenths value and the hundredths value of the number.

Answer:
10. y=-4x+3
12. y=[tex]\frac{1}{2}[/tex]x+3
Step-by-step explanation:
In order for a line to be perpendicular to another, their slopes must be opposite reciprocals.
1. Put the given equations into slope-intercept form. (y=mx+b)
2. Identify the opposite reciprocal of the original equations. (#10: -4 & #12: [tex]\frac{1}{2}[/tex])
3. Plug your given coords and opposite reciprocals into point-slope formula (y-y₁=m(x-x₁)) and simplify the expression to get your equation of the line.

Ricky draws a square . He claims that any rotation about the center of the square that is a multiple of 30 degrees will carry the square onto itself . Which statement best describes Ricky's claim ?
Answer:
Option (a)
Step-by-step explanation:
This question is incomplete without statements; find the statements as followed,
a). Ricky's claim is incorrect since not all rotations that carry a square onto itself are multiples of 30 degrees.
b). Ricky's claim is incorrect since not all rotations that are multiples of 30 degrees carry a square onto itself.
c). Ricky's claim is correct since any rotation that carries a square onto itself is a multiple of 30 degrees.
d). Ricky's claim is correct since any rotation that is a multiple of 30 degrees carries a square onto itself.
Square ABCD will map onto itself when point A comes to B, C or D by a rotation about the center E with a multiple of measure of angle AEB.
m∠AEB = 90° [Diagonals of a square intersect each other at 90°]
In simpler words, if square ABCD is rotated 90° or it's multiple about the center E, square will overlap itself.
Therefore, Option (a) is correct.
On a test a student got 15 problems correct out of a total of 20 problems. What percent did the student get, begin emphasis, incorrect, end emphasis,?
Answer:
I think what you got is correct
The percentage of incorrect problems is 25%.
Option D is the correct answer.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of problems = 20
Number of correct problems = 15
The number of incorrect problems.
= 20 - 15
= 5
The percentage of incorrect problems.
= 5/20 x 100
= 25%
Thus,
25% were incorrect problems

The total saved amount for Jorge, Janet and Rob is $55.8
Mathematical Expression
Mathematical Expressions are statements that have at least two terms that include numbers, variables, or even both, and are linked by an operator.
How to solve mathematical expression for the given condition?Jorge has saved $ 15.50
Janet's saving is [tex]\frac{1}{5}\times \$15.50[/tex]
That is, Janet has saved [tex]\$3.1[/tex]
Rob's saving is [tex]12\times\$3.1[/tex]

shawna is making a $12 per hour. she gets a 6% increase in pay.
ANSWER ASAPPPP PLZZZZ MARKING BRAINLIEST HELPPP
Answer:
12.72 dollars per hour
Step-by-step explanation:
Her original money is $12 per hour. We know that 6% in a decimal is 0.06. But if we multiply 0.06 and $12, it would get an answer that is decreasing than increasing. So we can get this equation. 12+0.06*12. ( 12 dollars plus 6% of 12 dollars) If we divide by 12, we get: 12( 0.06+1). 0.06+1=1.06. And 1.06*12 is 12.72 dollars per hour now. I hope this helps your question!

Step-by-step explanation:
d)P=2(l+b)
90=2(l+b)
l+b=90/2
l+b=45
A=l×b
500=lb
l=45-b

b(b-25)-20(b-25)=0
(b-20)(b-25)=0
b=20 or b=25
c)a×b=18
a+b=9
a=9-b
