Answer:

f(x) = -8(4)x

Step-by-step explanation:

The reflection of the point (x,y) across  the x-axis is the point (x,-y).

Having said this, to reflect the function y=g(x) = 8(4x) over the x-axis, we just need to evaluate the equation in the point: (x,-y).

y = 8(4x) ⇒ -y = 8(4x) ⇒ y = -8(4x)

Then f(x) = -8(4x)

Attached you will find the graph of g(x) (blue) and f(x) (red),

Answer:

[tex]f (x) = -8(4x)[/tex]

Step-by-step explanation:

The transformation that reflects the function [tex]g(x)[/tex] on the axis is:

[tex]y = -g (x)[/tex].

Therefore if we have the function

[tex]g (x) = 8 (4x)[/tex] and we call [tex]f (x)[/tex] to the transformation that relieves g (x) on the x axis then:

[tex]f (x) = -g (x)\\\\f (x) = -8(4x)[/tex]

Finally the equation for f(x) es:  [tex]f (x) = -8(4x)[/tex]

ANSWER

D. The graph of G(x) is the graph of F(x) shifted 7 units down.

EXPLANATION

The given assumption is that:

G(x)= F(x)-7

This implies that, our parent function is F(X).

Since 7 is subtracted from F(x) to obtain the graph of G(x), it means that shifting the graph of F(x) down by 7 units gives us the graph of G(x).

D. The graph of G(x) is the graph of F(x) shifted 7 units down.

Answer:

The measure of SWX is 108.

Step-by-step explanation:

TX and QS are not perpendicular.

QRT and TRU are complementary (add to 90) not supplementary (add to 180)

The measure of SWX is 108 because angles on a line add to 180, and RWS is 72. 180 - 72 = 108

Answer:

The measure of <SWX is 108°

The second answer is actually Complementary.

Answer:

If It was a Fraction it'd be 8/5

Step-by-step explanation:

Answer:

D 10/15 > 10/16

Step-by-step explanation:

The least common multiple of 2 and 5 is 10.

2/3 = 10/15

5/8 = 10/16

10/15 > 10/16

Answer: D.

Final answer:

When Loren compares 2/3 and 5/8 using a common numerator, he finds that by making both numerators 10 (10/15 and 10/16), 10/15 is less than 10/16, because the fraction with the larger denominator is the smaller fraction.

Explanation:

To compare the fractions 2/3 and 5/8 by rewriting them using a common numerator, Loren has to find a common multiplier for each numerator that would make them equal. He could multiply the numerators and denominators of both fractions by the other fraction's numerator. For 2/3, he would multiply by 5, and for 5/8, he would multiply by 2. This gives:

For 2/3: (2\*5)/(3\*5) = 10/15

For 5/8: (5\*2)/(8\*2) = 10/16

Now, Loren can compare the fractions easily since they have the same numerator:

Option C: 10/15 < 10/16

This is because, with the same numerator, the fraction with the larger denominator is the smaller fraction.

Answer: No

Step-by-step explanation:

Like terms are when the variables of two numbers are the same so they would not be like terms.

Example:

5x+7y Are not like terms because they have different variables

but...

5x+7x Are like terms because they have the same variable(x).

No it’s is not because the variables of both the numbers has to be the same.

Answer:

the answer is D:  the median of box plot B is greater than the median of box plot A.

Step-by-step explanation:

Answer: D. The median of box plot B is greater than the median of box plot A.

Step-by-step explanation:

We know that in a box-whisker plot, the vertical present in the box represents the median value of data and the length of box along the number line represents the interquartile range.

In the given picture, it can be seen that the box B is longer than box A.

It mean that the interquartile range of box plot B is greater than the interquartile range of box plot A.

Also, the vertical line in box A is present between 15 and 20 on number line but in box B it is present between 25 and 30.

It means that the median of box plot B is greater than the median of box plot A.

Answer:

67

Step-by-step explanation:

Total

= 43 + 69 + 48 + 37 + 85 + 57 + 95 + 102

= 536

Mean

= 536 ÷ 8

= 67

The mean of the given set of numbers is 67.

The mean, also known as the average, is calculated by adding up all the numbers in a set and then dividing the sum by the total number of values in the set.

To find the mean of the set of numbers 43, 69, 48, 37, 85, 57, 95, and 102, you need to add all the numbers together and then divide the sum by the total number of values, which is 8.

43 + 69 + 48 + 37 + 85 + 57 + 95 + 102 = 536

536 ÷ 8 = 67

Therefore, the mean of the given set of numbers is 67.

To find the x coordinate of the midpoint: (-2+6)/2

To find the y coordinate of the midpoint: (5+(-9))/2

Answer:

The mid point is (2, -2).

Step-by-step explanation:

Answer:

20 square units

Step-by-step explanation:

You count how many across the parallelogram is (which is 4) and you count how high it is (which is 5). Then you multiply 5×4* which equals 20 square units.

*The reason you do this is because base×hieght=area

Answer:

20 square units

Step-by-step explanation:

Area of a parallelogram formula = base times height

To find the length of the base we take end points of the base and use distance formula

[tex]distance =\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Two points are (1,0) and (5,0)

Distance = [tex]\sqrt{(5-1)^2+(0-0)^2}[/tex]

[tex]=\sqrt{4^2} =4[/tex]

Length of base = 4 units

Now we find out the height between B (1,0) and D (1,5)

Height =[tex]\sqrt{(1-1)^2+(5-0)^2}=\sqrt{5^2}= 5[/tex]

Height = 5

Area of the parallelogram = base times height

= [tex]4 \cdot 5= 20[/tex]

So area = 20 square units

Factor −16t2+20t

−16t2+20t

=4t(−4t+5)

Answer:

4t(−4t+5)

or

Let's simplify step-by-step.

−16t2+20t

There are no like terms.

Answer:

=−16t2+20t

The equation f(t)=-16t^2+20 when solved gave t = 0 and t = 1.25.

To solve the quadratic equation f(t)=-16t^2+20t, we first need to rearrange it into the standard form of a quadratic equation at^2 + bt + c = 0. We can simplify the original equation by dividing all terms by -4, which will reverse the signs:

4t^2 - 5t = 0

Now, this equation can be factored, giving us:

t(4t - 5) = 0

This means our equation has two possible solutions for when it equals zero:

t = 0 or 4t - 5 = 0

Solving the second part for t gives us t = 5/4 or 1.25.

Therefore, the equation f(t) = -16t^2 + 20t has two solutions for t: t = 0 and t = 1.25.

Answer:

The percent decreased of the number of visitors to Alec’s website

  from February to March is 9.1%

Step-by-step explanation:

* Lets talk about the percentage of increase and decrease

- Percent of Increase (Decrease) =

 (amount of increase or decrease ÷ original amount) × 100%

- Increase {New amount > Original amount}    

- Decrease {Original amount > New amount}

* Now lets solve the problem

- The number of visitors in February is 1518

- The number of visitors in March is 1380

- The number in March < the number in February

∴ The decreasing amount = 1518 - 1380 = 138 visitors

∵ The original number = 1518

∴ The percent decreased = (138 ÷ 1518) × 100% = 9.1%

* The percent decreased of the number of visitors to Alec’s website

  from February to March is 9.1%

Answer:

The positive zero is 11

Step-by-step explanation:

Given in the question an equation,

f(x) =x² - 121

We are asked to find the positive zero of f(x)

means x > 0 for which f(x) = 0

so,

 x² = 121

Take square root on both sides of the equation

√x² = √121

  x =  ±11

which means that x = 11 and x = -11

Since x > 0 so we will reject x =-11 and we will accept x = 11

Answer: 11

Step-by-step explanation:

You need to substitute [tex]f(x)=0[/tex] into the function given:

[tex]f(x) =x^2-121\\0 =x^2-121[/tex]

Now you need to solve for the variable "x", to do this, first you must add 121 to both sides of the function:

[tex](121)+0=x^2-121+(121)\\121=x^2[/tex]

Now apply square root to both sides of the function. Then, you get:

[tex]\±\sqrt{121}=\±\sqrt{x^2}\\\\\±\sqrt{121}=x\\\\x_1=11\\x_1=-11[/tex]

The value of the positive zero of the function is 11.

Sin E=0.50

Step-by-step explanation:

Here we are given that DE || AB, and DB and AE are traverse lines to them meeting at point F.

By the properties of parallel lines intersected by a transverse we know that the alternate interior angles are equal.

If we extend DE and AE on both sides , we can see that A and E are equal as they forms alternate interior angles.

Hence

A=E

Sin A = Sin E

0.50=Sin E
