Step-by-step explanation:

solve expression using pemdas

(shown in image)

Step-by-step explanation:

Using the concept of inverse function, it is found that the first graph shows a function whose inverse is also a function.

----------------------------------------

A function f(x) will only have an inverse function if: f(a) = f(b) \leftrightarrow a = bf(a)=f(b)↔a=b , that is, a value of y will have only one respective value of x.

----------------------------------------

In the first graph, for each value of y, there is only one value of x, so the inverse is also a function, and this is the correct option.

In the second graph, for example, y = 0 when x = -1 and when x = 1, so the inverse is not a function.

In the third graph, for example, y = -3 when x = 0 and x = 2, so the inverse is not a function.

In the fourth graph, for example, y = 1 for two values of x, so the inverse is not a function.

Answer:

0.364

Solution:

Showing the work

We know that

411

is the same as

4÷11

Then using

Long Division for 4 divided by 11

and rounding to a Max of 3 Decimal Places gives us

=0.364

From either side of x = -2, f(x) approaches -5. The plot also shows it's continuous there, so each of these have a value of -5.

Work Shown:

L = d+9 = length along the horizontal

W = 10 feet = width along the vertical

P = 2(L+W) = perimeter of rectangle = 70 feet

70 = 2(d+9+10)

70/2 = d+19

35 = d+19

d+19 = 35

d = 35-19

d = 16

The deep end is 16 feet wide

Step-by-step explanation:

We let A be the set of those who owned an iPhone, B be the set of those who owned a Blackberry,

and C those that owned an Android. Therefore we have |A| = 60, |B| = 75, and |C| = 30. Also,

we know that |A ∩ B| = 40, |A ∩ C| = 12 and |B ∩ C| = 8. Finally, |A ∩ B ∩ C| = 3. Therefore,

by the principle of inclusion/exclusion, we have

|A ∪ B ∪ C| = |A| + |B| + |C| − |A ∩ B| − |A ∩ C| − |B ∩ C| + |A ∩ B ∩ C|

= 60 + 75 + 30 − 40 − 12 − 8 + 4

= 109

(a) Since there are 300 total people, there are 191 without one of the types of phone.

(b) Since |A ∩ B| = 40 and |B| = 75, there are 35 people with a Blackberry that don’t own

an iPhone.

(c) Since |B ∩ C| = 8 and |B| = 75, there are 67 people with a Blackberry that don’t own

an Android.

Answer:

Step-by-step explanation:

You can read f(x) to mean y. y is above the x axis between -2 and - 6. To put it more formally,

-6 <x <-2

Why don't you use ≤ ?

It's because where is f(x) positive? 0 is not a positive value,, so you cannot use the endpoints.

Answer:

The dimensions that minimize the cost of materials for the cylinders have radii of about 3.628 cm and heights of about 7.256 cm.

Step-by-step explanation:

A cylindrical can holds 300 cubic centimeters, and we want to find the dimensions that minimize the cost for materials: that is, the dimensions that minimize the surface area.

Recall that the volume for a cylinder is given by:

[tex]\displaystyle V = \pi r^2h[/tex]

Substitute:

[tex]\displaystyle (300) = \pi r^2 h[/tex]

Solve for h:

[tex]\displaystyle \frac{300}{\pi r^2} = h[/tex]

Recall that the surface area of a cylinder is given by:

[tex]\displaystyle A = 2\pi r^2 + 2\pi rh[/tex]

We want to minimize this equation. To do so, we can find its critical points, since extrema (minima and maxima) occur at critical points.

First, substitute for h.

[tex]\displaystyle \begin{aligned} A &= 2\pi r^2 + 2\pi r\left(\frac{300}{\pi r^2}\right) \\ \\ &=2\pi r^2 + \frac{600}{ r} \end{aligned}[/tex]

Find its derivative:

[tex]\displaystyle A' = 4\pi r - \frac{600}{r^2}[/tex]

Solve for its zero(s):

[tex]\displaystyle \begin{aligned} (0) &= 4\pi r - \frac{600}{r^2} \\ \\ 4\pi r - \frac{600}{r^2} &= 0 \\ \\ 4\pi r^3 - 600 &= 0 \\ \\ \pi r^3 &= 150 \\ \\ r &= \sqrt[3]{\frac{150}{\pi}} \approx 3.628\text{ cm}\end{aligned}[/tex]

Hence, the radius that minimizes the surface area will be about 3.628 centimeters.

Then the height will be:

[tex]\displaystyle \begin{aligned} h&= \frac{300}{\pi\left( \sqrt[3]{\dfrac{150}{\pi}}\right)^2} \\ \\ &= \frac{60}{\pi \sqrt[3]{\dfrac{180}{\pi^2}}}\approx 7.25 6\text{ cm} \end{aligned}[/tex]

In conclusion, the dimensions that minimize the cost of materials for the cylinders have radii of about 3.628 cm and heights of about 7.256 cm.

Answer:

252 Inches cube

Step-by-step explanation:

So for this question you need to find the area of cross section which is the H,

2 Times (3 Inches by 7 Inches) {The 2 same shape}

+

3 Inches by 7 Inches {The middle shape}

For the H Shape = 63 Inches Square

Then you'll time the lenght which is given 4 Inches

63 Inches square ×4 Inches

252 Inches Cube

The volume of this shape will be 252 Inches cube

Step-by-step explanation:

To create a perpendicular bisector, you need a compass, a straightedge, and a pencil. As well as the line segment AB drew down.

1> You start by opening the compass and stretching it to a width greater than half the length of AB.

2> Then you simply place one point of the compass on the line segments A. From here, you move the compass and draw arcs above and below the line AB.

3> Without moving the compass measure, remove it from point A and place it onto point B. You basically repeat step 2 by drawing arcs above and below the line again.

4> If you've done it right, the arcs should be in the middle, X and Y, and using a straightedge/ruler you draw a line that goes vertically through where they connect.

and that should be your perpendicular bisector using segment AB.

  -$25  (a loss of $25)

Step-by-step explanation:

Profit is the difference between revenue and cost.

  profit = $150 -175 = -$25

The cheerleaders took a $25 loss on their bake sale.

Additional comment

The wording "made $150" can be interpreted two ways. We have taken it to mean the revenue from sales was $150. The same wording could also be used to indicate the profit was $150.

Answer:

12 Edges

Step-by-step explanation:

Top one is right but had 2 stars for some reason. 12 Edges is the answer. (Just did it btw)

Edges of a polyhedron are 12.

"Polyhedron is a three dimensional solid shape with a certain number of faces, edges and vertices.

If the number of faces and the vertex of a polyhedron are given, we can find the edges using the polyhedron formula. This formula is also known as ‘Euler’s formula’."

F + V = E + 2

Here,

F = Number of faces of the polyhedron

V = Number of vertices of the polyhedron

E = Number of edges of the polyhedron

Given

Number of Faces (F) = 7

Number of Vertices (V) = 7

For any polyhedron,

Euler's Formula:

F + V - E = 2

⇒ 7 + 7 - E = 2

⇒ 14 - E = 2

⇒ E = 14 - 2

⇒ E = 12

Number of Edges (E) = 12

Hence, Edges of a polyhedron are 12.

Answer:

  $13.60

Step-by-step explanation:

Julio worked 35 -31 = 4 overtime hours. For those 4 hours, he was paid at the rate 1.2r. Then his earnings were ...

  31r +4(1.2r) = 486.88

  35.8r = 486.88

  r = 486.88/35.8 = 13.60

Julio's normal hourly rate is $13.60.
