Answer:

The coordinates of point C' are (4, -2)

here's why:

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y). So if we use this information with the original coordinates, (-4, -2), the new coordinates will be (4, -2).

Answer:

477 boys would be there.

Explanation:

boys to girls is 2:3

3 units --->  716

1 units ---> (716/3)

then boys ---> (716/3) * 2

                ---> 477 boys

Or basically:

(716/3) * 2

477 boys

Step-by-step explanation:

Here we will, Provide index power 5 on both the sides, so that we can cancel out the 5th power root in the L.H.S

so we get as,

==> x+7 = (-2)^5

==> x+7 = -32

==> x = -32-7

==> x = -39

hence, x = -39

Option A.) is correct.

The population of the United States in 2008 is 298528793.

Gross domestic product (GDP) is the total monetary or market value of all the finished goods and services produced within a country's over a specific time period

GDP per person = GDP / Population

From the question, GDP = $14.204 trillion, GDP per person was $47,580. Hence:

47580 = 14.204 * 10¹² / Population

Population = 298528793

In inequalities, each equation will be shaded a certain direction/side, and anything in that shaded region is a solution to the equation. With 2 inequalities, the solutions to the equations will be in the double-shaded region.

Also, inequalities will either have a dotted (- - - - -) line or a solid (───) line. You will use a dotted line for inequality equations with > or < symbols, and solid lines for inequality equations with ≥ and ≤ symbols.

Using the formula for the volume of a rectangular prism, it is found that it would hold 1110 feet of shipped goods when it’s half full.

The volume of a rectangular prism with length l, width w and height h is given by:

[tex]V = lwh[/tex]

In this problem, considering that 12 inches represent a feet, we have that:

Considering it would be half full, the volume is multiplied by 0.5, then:

[tex]V = 0.5(30)(8)(9.25) = 1110[/tex]

It would hold 1110 feet of shipped goods when it’s half full.

Step-by-step explanation:

The length DE is the hypotenuse of triangle CDE

The length DE is [tex]\frac{\sqrt{61}}2[/tex]

The given parameters are:

[tex]AD =3[/tex]

[tex]CB = 5[/tex]

Given that line DE bisects AC and CB, it means that:

[tex]CD = AD = 3[/tex]

[tex]CE = EB = 2.5[/tex] i.e. CB/2

So, we have:

[tex]DE =\sqrt{AD^2 + CE^2[/tex] --- Pythagoras theorem

Substitute known values

[tex]DE =\sqrt{3^2 + 2.5^2[/tex]

[tex]DE =\sqrt{15.25[/tex]

Express as fraction

[tex]DE =\sqrt{\frac{61}{4}[/tex]

Simplify

[tex]DE =\frac{\sqrt{61}}2[/tex]

Hence, the length DE is [tex]\frac{\sqrt{61}}2[/tex]

Answer:

The family's average rate of travel for the day was 59.0 MPH.

Step-by-step explanation:

From 10:15AM to 4:45PM, they travelled a distance of 383.5 miles and a total of 6 hours and 30 minutes.

There are 60 minutes in an hour. 30 minutes translates into 1/2 an hour or .5

So, 6.5 hours and a total distance of 383.5 miles.

Velocity (MPH) = Distance (in miles) / Time (in hours)

MPH means Miles Per Hour

Variables:

Velocity (MPH) = x

Distance (in miles) = 383.5

Time (in hours) = 6.5

Plug in the variables into the formula

x = 383.5 / 6.5

Divide

x = 59.0 MPH

Answer:

59 miles/hr

Step-by-step explanation:

To solve this, lets make the time in 24 hours format:

10:15 am = 10 hours and 15 minutes

4:45 pm = 16 hours and 45 minutes

so time taken = ( 16 hours and 45 minutes ) - ( 10 hours and 15 minutes )

                       = 6 hours 30 minutes

                       = [6 + (30/60)] hours

                       = 6.5 hours taken for the journey to complete

Average rate of travel = Total distance / time taken

                                     = 383.5 / 6.5

                                     = 59 miles/hr

Step-by-step explanation:

screens are measured from corner to corner meaning that from the top left to bottom right the tv is 72 inches

since we know the tv is 36 in tall and 72 across we can use the Pythagorean theorem to find how wide it is by doing 72^2-36^2

so the tv is 62.35 in wide

so it will fit in the 70-inch wide gap

The area of the rectangle will be 35cm²

The formula for calculating the area of a rectangle is expressed as:

A = lw

If the width of a rectangle is 2 cm longer than its length, then;

w = l + 2

Substitute the given values into the formula:

A = l(l+2)

A = l² + 2l

Given the following parameters:

l = 5cm

A = (5)² + 2(5)

A = 25 + 10

A = 35cm

Hence the area of the rectangle will be 35cm²

at x =1 f(x) =0

so the value of the domain is x=1

Answer:

x = 1

Step-by-step explanation:

So you would be looking at where y axis is 0, which is x intercept

Looking at the image, you can see that the line go across at x = -0.5 and x = 1, and that's the answer because x = -0.5 is not an answer choice

THE ANSWER: the answer is 58°

Answer:

-5 - 4x

Step-by-step explanation:

First distribute the -3.

7 - 3 (4 - 2x) - 10x = 7 - 12 + 6x - 10x

Subtract 12 from the 7 at the front of the expression.

7 - 12 + 6x - 10x = -5 + 6x - 10x

Now subtract the 10x from the 6x at the back of the expression.

-5 + 6x - 10x = -5 + -4x

-5 + -4x = -5 - 4x
