A. 34
B. 36.5
C. 73
D. 107

Answers

tangent lines are perpendicular to their intersection point so add 17 and 90 then subtract 107 to 180 to get {[(73)]}

Answer:

Option C. 73

Step-by-step explanation:

In the given figure Δ OPQ is the right angle triangle because radius is always perpendicular to the tangent drawn on the circle from an external point.

Here OQ is radius and PO is tangent.

So ∠OQP = 90°

Now sum of all angles of a triangle is 180°

Therefore, ∠OPQ + ∠OQP + ∠POQ = 180°

17° + 90° + x° = 180°

107 + x = 180

x = 180 - 107

x = 73°

Write an equation to match each graph:

Answers

the equation should be y=|x| BUT i am not 100%. there would be no shifts because the vertex is on the origin.

Write an equation to match each graph.

Solution:

The first graph is V shaped graph centered at origin, (0,0) and the graph is not shifted or translated. So, the equation of first graph is,

y=|x|

The second graph is V shaped graph centered at (1,0) and y=|x| is horizontally shifted right by 1 unit. So, the equation of second graph is,

y=|x-1|

The third graph is also V shaped but, it is inverted V graph centered at (0,1) . As, the graph is inverted V So, the graph must have y=-|x|. But, as the center is (0,1). So, the graph is shifted up by 1 unit. So, the equation of the third graph is,

y=-|x|+1

The fourth graph is shifted V graph, whose center is (1,-1). So, y=|x| is shifted right by 1 unit and down by 1 unit. So, the equation of fourth graph is,

y=|x-1|-1

The center of fifth graph is (-1,0), So, y=|x| graph is shifted left by 1 unit. So, the equation of fifth graph is

y=|x+1|

Maggie only wore sandals tracker on two of the days that she trained so from her fitness trackers she verified that on the third day she biked 20 miles and on the eighth day she biked 35 miles use these two data points to determine the equation of the line best of fit set for Maggie’s data

Answers

We know form our problem that the third day she biked 20 miles, so we have the point (3,20). We also know that on the eighth day she biked 35 miles, so our second point is (8,35).

To relate our two point we are going to use the slope formula: [tex]m= \frac{x_{2}-x_{1}}{y_{2}-y_{1}} [/tex]
We can infer form our points that [tex]x_{1}=3[/tex], [tex]y_{1}=20[/tex],[tex]x_{2}=8[/tex], and [tex]y_{2}=35[/tex]. so lets replace those values in our slope formula:
[tex]m= \frac{35-20}{8-3} [/tex]
[tex]m= \frac{15}{5} [/tex]
[tex]m=3[/tex]

Now that we have the slope, we can use the point-slope formula determine the equation of the line that best fit the set for Maggie’s data.
Point-slope formula: [tex]y-y_{1}=m(x-x_{1})[/tex]
[tex]y-20=3(x-3)[/tex]
[tex]y-20=3x-9[/tex]
[tex]y=3x+11[/tex]

We can conclude that the equation of the line that best fit the set for Maggie’s data is [tex]y=3x+11[/tex].

Amanda owns a clothing store that sells graphic t-shirts. n is the number of shirts she sells each month. the revenue function of her store is r = 25n. the cost function of her store is c = 10n + 900. using your calculator, what is the break-even point of amanda's store?

Answers

The break-even point will be attained when the revenue is equal to the cost. That is
[tex]25n=10n+900[/tex]
[tex]25n-10n=900[/tex]
[tex]15n=900[/tex]
[tex]n=60[/tex]

The break-even point is attained when n equals 60.

Answer:

n = 60 shirts

Step-by-step explanation:

The break-even point is the point where revenue is equal to cost. This means we take the equation for revenue, r = 25n, and set it equal to the equation for cost, c = 10n + 900:

25n = 10n + 900

Subtract 10n from each side:

25n - 10n = 10n + 900 - 10n

15n = 900

Divide both sides by 15:

15n/15 = 900/15

n = 60

Christine runs 7 miles in 60 minutes. at the same rate, how many miles would she run in 24 minutes?

Answers

Let x = the unknown amount of miles she would run. We are going to set up a proportion.

[tex] \frac{7 miles}{60 min} = \frac{x miles}{24 min} [/tex]

Now we are going to cross-multiply and solve for x.

60x = 7(24)
60x = 168
x = 168 / 60
x = 2.8

Christine runs 2.8 miles in 24 minutes.

Final answer:

Christine would run approximately 2.8 miles in 24 minutes at the same rate she runs 7 miles in 60 minutes.

Explanation:

To find out how many miles Christine would run in 24 minutes, we can set up a proportion. We know that Christine runs 7 miles in 60 minutes, so we can write the proportion as:

7 miles / 60 minutes = x miles / 24 minutes

Now, we can cross-multiply and solve for x:

7 * 24 = 60 * x

168 = 60x

x = 168 / 60

x ≈ 2.8 miles

So, her speed would be 7/60 = 0.1167 miles per minute. Now, to find out the distance she would cover in 24 minutes at this speed, we multiply her speed per minute by 24 minutes. So, 0.1167 * 24 = approximately 2.8 miles. Therefore, at the same rate, Christine would run about 2.8 miles in 24 minutes.

Of the following options, what could be a possible first step in solving the equation −7x − 5 = x + 3?
Adding 7x to both sides of the equation
Subtracting 5 from both sides of the equation
Adding x to both sides of the equation
Combining like terms, −7x + x = − 6x

Answers

Adding 7x to both sides makes the most sense. It would cancel out with the -7x, leaving you with -5 = 8x + 3.

Subtracting 5 from both sides wouldn't cancel anything out, adding x to both sides wouldn't cancel anything out, and you can't combine like terms on either side of the equation.

add 7x to both of the sides

Answer:

Hence, the correct options are Polyhedron, Pyramid and Solid

Step-by-step explanation:

According to the options, we have,

1. Polyhedron is a solid figure in three dimensions having polygons as its faces along with sharp vertices and straight edges.

So, we can see that the given figure have polygonal faces with sharp vertices and straight edges.

Thus, it is a polyhedron.

2. Polygon is a closed two dimensional figure bounded by straight lines.

But, the given figure is not a 2-D figure and so is not a polygon.

3. Prism is a polyhedron with polygons as its faces along with a second base which is a translated copy of the first base.

Since, the given figure is a polyhedron but it does not have a second base which is a translated copy of the first base.

So, the given figure is not a prism.

4. Pyramid is 3-D figure having triangular outer surfaces converging to single point with polygonal base.

As, we can see that the given figure have polygonal base and triangular sides converging to a point.

So, the given figure is a pyramid.

5. Cube is a 3-D figure with all the six faces as squares.

But, the given figure does not have square faces and so is not a cube.

6. Solid is a figure having three dimensions.

Since, the given figure does have three dimensions.

So, it is a solid.

Hence, the correct options are Polyhedron, Pyramid and Solid.

Answers

The value of m must be greater than the value of n. When you multiply the binomials, the middle term is the result of combining the outside and inside products. So, bx = –nx + mx, or bx = (–n + m)x. This means that b = –n + m. When adding numbers with opposite signs, you subtract their absolute values, and keep the sign of the number having the larger absolute value. Since b is positive, mmust have the larger absolute value.

The number N is the produce of the first 1000 positive integers and can be written as 1000!.We say "1000 factorial."This is, N=1000!=1000x999x998x997x...x3x2x1.N is divisible by 5, 25, 125, 625,...Each of these factors is a power of 5.That is 5=5^1, 25=5^2, 125=5^3,625=5^4, and so on. Determine the largest power of 5 that divides N.

Answers

From 1000 to 1, there are 200 numbers that are divisible by 5, which means that 1000! is divisible by at least 5^200.Then there are 40 numbers that are divisible by 25 (5^2), so this adds another 5^40.Then there are 8 numbers divisible by 125 (5^3), so this adds another 5^8.Finally, 1 number is divisible by 625 (5^4), so this adds 5^1.
Therefore, the total sum is 5^(200+40+8+1) = 5^249. Therefore, the largest N = 249.

What is dot plot?

A dot plot, also referred to as a dot chart or stripe graph, is a sort of simple histogram-like figure used in statistics for little data sets with values falling into a number of discrete bins.

Since the width of each "bar" of dots is equal to the number of items in a certain class, a dot plot is similarly to a bar diagram.
