Answer:

1.17*10^14 km

Step-by-step explanation:

kindly find attached the image for your reference

Step one:

The diameter of Mars is approximately 6794 km

hence the radius is = 6794/2= 3397km

Step two:

Use the Pythagorean Theorem

[tex]x^2 + 3397^2 = (3397 + 25)^2\\\\[/tex]

[tex]x^2 + 11539609 = (11710084)^2\\\\x^2 + 11539609 = (11710084)^2\\\\x^2= (11710084)^2-11539609 \\\\x^2= 1.37*10^14-11539609 \\\\x^2=1.37*10^14\\\\x= √1.37*10^14\\\\x=1.17*10^14 km[/tex]

Answer:

im trying to get 50 points

Step-by-step explanation:

Answer:

The pipe lengths are 50 inches and 100 inches.

Step-by-step explanation:

If we refer to the length of the shorter piece as x, then we can say the length of the larger piece is 2x.  We are also told that the pipe length is 150 inches, so we can say:

x + 2x = 150

3x = 150

x = 150/3

x = 50

So the pipe lengths are 50 and 100 inches respectively.

Answer:

-.82

Step-by-step explanation:

To find the average rate of change over an interval, you use rise over run with the first point and the last point (in this case, the first point is (50, 35.8) and the last point is (60, 27.6)). This will give you an average rate of change of -.82.

In the context of this problem, -.82 is how much your expected remaining life span decreases each year.

120+120+125+95+x+x+84 = 720

544+2x = 720

2x = 176

x = 176/2

x = 88

Answer:

Step-by-step explanation:

you must solve first

18x < 45

x < 2.5

the number line will have an arrow with an open circle since it does not include 2.5. the line will head towards 0 and negatives since it's less than 2.5 so your answer is D

Step-by-step explanation:

Step 1: Define

m/2

m = -8

Step 2: Evaluate

Answer: -4

Step-by-step explanation: It's important to understand that m/2 means

the same thing as m ÷ 2.

In this case, we are given that m = -8.

So we have -8 ÷ 2 which is -4.

Remember that when you divide a negative number

Look at the line carefully. You can see that the line crosses the point (0,2). See it? The value of 2 in the point (0,2) is the y-intercept.

The given equations are all in the form

y = mx + b, where b is the y-intercept.

So, based on this data, we conclude that the line represents the equation y = (1/3)x + 2.

Choice C is the answer.

Answer:

20

Step-by-step explanation:

To evaluate, substitute x = 6 into f(x) , that is

f(6) = 2(6) + 8 = 12 + 8 = 20

[tex]f(x)=2x+8[/tex]

Substitute x = 6 in the equation.

[tex]f(6)=2(6)+8\\f(6)=12+8\\f(6)=20[/tex]

Therefore, the answer is f(6) = 20.

The last choice.

The graph that has the slope that best represents the unit rate of 4 miles per hour is: graph B.

For any proportional relationship, we can find the slope of the graph by using any point on the line of the graph. The slope of the graph is also the unit rate, Therefore, picking a point on the line, (x, y), we have:

Slope (m) = y/x.

Number of miles Tyrell walks (y) = 12 miles

Time spent working (x) = 3 hours

The unit rate or slope = y/x = 12/3

Slope/unit rate (m) = 4 miles per hour.

From the graphs given, only graph B has the same unit rate/slope as 4, when we use the point, (5, 20).

Slope of graph B = 20/5 = 4.

Therefore, the graph that has the slope that best represents the unit rate of 4 miles per hour is: graph B.

Fill in the inequalities below to specify the graph's range shown.

Range: __ is not greater than or equal to y, which is below 5.

The domain and range is the graph's domain is its set of potential input values, and its range is its set of potential output values.

Following is the finished inequality reflecting the set of the domain and range;

First,

Domain: -4 is below x, which is below or equal to 4.

Second,

Range: -2 is below y, which is below or equal to 5

The attached graph shows that the point (-4, 5) has an open circle, which denotes that the point has no value.

The closed circle at the other end of the graph, at the coordinates (4, -2), denotes that the graph has a value at that location (4, -2)

First,

The domain of a graph is the set of potential inputs (x-values) for the graph, expressed as inequality is -4 < x ≤ 4

Therefore;

To complete the inequality for the domain, gives;

Domain: -4 is less than x which is less than or equal to 4

Second,

The range of a graph are the possible output (y-values) of the graph, in inequality notation, the domain of the attached graph is -2 ≤ y < 5

the domain supplies the necessary inequality to be complete;

Range: -2 is less than or equal to y which is less than 5.
