Can Someone Please Help Me With This Math Question

Answers

Answer 1

Answer:

The answer would be D

Step-by-step explanation:

Most of the points are grouped together and can be define by a line or equation so there is a correlation between the outside temperatures and the heating cost so right away we can eliminate option A

There is no such thing as a constant correlation so we can eliminate answer choice C

As the temperatures rise ( or as the x values rise) the cost of heating decreases ( or the y values decrease) This is an example of negative correlation correlation because as one value increase the other value decreases.

this is also notable from looking at the graph .

Given the first term and common ratio: Find the 10th Term. The first term is equal to 1 and the common ratio is
equal to -2.

Answers

Answer:

-512

Step-by-step explanation:

The appropriate general formula for a geometric series is a(n) = a(1)*r^(n - 1).

In this problem the first term, a(1) = 1, and the common ratio is r = -2.  The pertinent geometric series is thus:

a(n) = (-2)^(n - 1), and the 10th term is a(10) + (-2)^(10 - 1) = -512 = a(10)

The graph below shows how far a ship is traveling in a certain amount of time.

How far will the ship travel in 4 hours?

50 miles

100 miles

4 miles

75 miles

Answers

Answer:

100 miles

Step-by-step explanation:

Remark

All you need do is start at 4 hours on the y axis and go right until you hit a dot. When you do, go down until you hit a number on the x axis.

It helps if you mark up the graph.

Go right from 4

You hit a dot

Look down.

You should see 100. That's how far you go in 4 hours.

Note

This is an odd graph. Usually time is on the x axis.

Mike walked 5/8 of the way to school before it started raining.how many percent of the trip did he get before it rained ​

Answers

Answer:

62.5%

Step-by-step explanation:

To find the percent, divide 5 by 8, and multiply it by 100:

5/8

= 0.625

0.625(100)

= 62.5

So, Mike walked 62.5% of the trip

Answer:

62.5%

Step-by-step explanation:

5/8 As A Decimal Is 0.625

So  Inequalify 5/8.   So, 62.5/100

then convert 0.625 by 5/8, Which is 62.5.

So your answer is 62.5%.

Find the distance between the pair of points. ​(4​,1) and ​(9​,6​)

Answers

Answer:

5√2 or 7.07 units

Step-by-step explanation:

To find the distance between two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Plug in the given values of (4​,1) and ​(9​,6​)

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

d = √[(9 - 4)² + (6 - 1)²]

Simplify the parentheses.

d = √[(5)² + (5)²]

Simplify the exponents.

d = √[25 + 25]

Add.

d = √[50]

Evaluate the radical.

5√2 or 7.07

Round the decimal.

5√2 or 7.07 units

Answers

Answer:

y = 2x - 2

Step-by-step explanation:

Points on graph: (4,6) and (2, 2)

Slope:

m=(y2-y1)/(x2-x1)

m=(2-6)/(2-4)

m=(-4)/(-2)

m = 2

Slope-intercept:

y - y1 = m(x - x1)

y - 6 = 2(x - 4)

y - 6 = 2x - 8

y = 2x - 2

To lease a new car, you must make a down payment when you sign the lease, then pay $199 per month. Six months after signing his lease, Mr. Scott had paid $2,694. Write and solve an equation to find the total amount he will have paid after 2 years.

Answers

The solution for this problem is:

Let x be the number of months; and

Let y be the amount paid

We know that m is $199 per month and the two other given are 6 months and 2694.

 

y = 199 (x -6) + 2694

y = 199 (36 -6) + 2694

y = 199 (30) + 2694

y = 8664

 

Mr. Scott paid $8664 after 3 years.

As the triangle is similar angle don't change so 50+70=120 and the angle of a triangle total to 180 so 180-120=60

Answer:

60°

Step-by-step explanation:

As it is said that the triangles are similar so In the similar triangles corresponding angles are equal so

< A = 50°

<E = 70°

< B = < E = 70° { being corresponding angles of similar triangles }

Now

< A + <B + < C = 180° {Being sum of angles of triangle }

50° + 70° + < C = 180°

< C = 180° - 120°

< C = 60°
