Answer:

f(-4) = 4

Step-by-step explanation:

We know that f(x) = y.

We also know that f(-4) means that x = -4.

The y value of (-4, y) is 4, therefore... f(-4) = 4.

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

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.

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!

let T represents the outcome of tails.

if the coin is tossed 3times The total number outcomes are

HHH, HHT, HTH, HTT, THH, THT, TTH, TTT

Answer:

I think what you got is correct

The percentage of incorrect problems is 25%.

Option D is the correct answer.

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

Answer:

He can run 112 yards in 12 seconds

Step-by-step explanation:

Here, we want to know the number of yards he can run in 12 seconds

From the question, we are told that his running rate is 38 yards in 4 seconds

So the number of yards he can run in 12 seconds will be;

38 * 12/4

= 38 * 3 = 114 yards

The total saved amount for Jorge, Janet and Rob is $55.8

Mathematical Expressions are statements that have at least two terms that include numbers, variables, or even both, and are linked by an operator.

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]

Thus, Rob has saved [tex]\$37.2[/tex]

So, the mathematical expression for the total saved amount of all three is given below.

$15.50 + $3.1 + $37.2 = $55.8

Simplify the above mathematical expression.

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.
