A hot air balloon is at an elevation of 1,250 feet. Its elevation begins to change at a rate of -22.5 feet per minute. How many minutes will it take the balloon to descend to an elevation of 935 feet? Use the Distance Formula: d = rt

Answers

Let y represent the number of feet and x represent the number of minutes.  Convert 22 1/2 to decimal form: 22.5

 

y = -22.5x

 

Plug in -315 for y

 

-315 = -22.5x

 

divide both sides by -22.5

 

14 = x

 

It will take 14 minutes.

If f(x) = 2x and g(x) = 5x + 2, what is (f + g)(x) when x = 3?

Answers

Answer:

f÷g=2x+5x+2=7x+2

x=3

7×3+2=21+2=23

The value of  (f + g)(x) when x = 3, if f(x) = 2x and g(x) = 5x + 2, is 23.

What is function?

The function is a relationship between a set of potential outputs and a set of possible inputs, where each input has a single relationship with each output. This means that if an object x is present in the set of inputs (also known as the domain), then a function f will map that object to exactly one object f(x) in the set of potential outputs (called the co-domain).

Given:

f(x) = 2x and g(x) = 5x + 2

Calculate  (f + g)(x)  as shown below,

f(x) + g(x) = 2x + 5x +2

f(x) + g(x) = 7x + 2

Put x = 3

f(3) + g(3) = 7 × 3 + 2

f(3) + g(3) = 23

Find the equation of the line that contains the point p(3,5) and is parallel to the graph of 5x+y= -2

Answers

9514 1404 393

Answer:

  5x +y = 20

Step-by-step explanation:

The equation of the parallel line will have the same x- and y-coefficients. The constant will be adjusted to make the equation true at the given point.

  5x +y = 5(3) +(5) = 20

The parallel line is ...

  5x +y = 20

A natural gas company charges a fixed customer fee of $ 12.60 every
month even if no natural gas is used. For every unit of natural gas used,
the customer is charged an additional $0.64.
a. Using x as the number of units used in a month and y as the total
monthly cost, write an equation

Answers

Y=12.60+0.64x

$0.64 is charged for each unit which is represented by x. Therefore .64 is multiplied by x. 12.60 is the charge you have no matter what every month. So if you don’t use any gas you would still pay $12.60.

y = 12.60 + 0.64x

Step-by-step explanation:

y = $12.60 + $0.64(x)

y = 12.60 + 0.64x

Which of the following equations represents an ellipse having vertices
located at (2,9) and (2,-5) and foci located at (2,5) and (2,-1)?

Answers

Answer:

(x-2)^2/40 + (y-2)^2/49 = 1

Step-by-step explanation:

Write the equation for the function graphed below.

Answers

Given the vertex, (2, 7), and that it is a downward-facing parabola:

We can use the vertex form of the quadratic function:

f(x) = a(x - h)^2 + k
where:

Vertex = (h, k)

“a” determines whether the graph opens up or down.

* If “a” is negative, the graph opens down.

The value of “a” also makes the parent function wider or narrower.

The value of “h” determines how far left or right the parent function is translated.

The value of “k” determines how far up or down the parent function is translated.

Given these information, we can plug in the value of the vertex into the vertex form:

f(x) = a(x - h)^2 + k

f(x) = a(x - 2)^2 + 7

Next, to solve for “a”, we can use one of the points on the graph, (1, 5), and plug these values into the equation:

f(x) = a(x - 2)^2 + 7

5 = a(1 - 2)^2 + 7

5 = a(-1)^2 + 7

5 = a(1) + 7

Subtract 7 from both sides:

5 - 7 = a(1) + 7 - 7
-2 = a

Therefore, a = -2. Now, we can establish the following quadratic function in vertex form:

f(x) = -2(x - 2)^2 + 7

Step-by-step explanation:

a) One way you can try to identify the pattern is to look for the differences between the images shown, then divide those differences by 2. For example, the total number of vertical dots is 2, then 4 in patterns 2 and 4. This suggests the total number of vertical dots is equal to the pattern number..

The total number of horizontal dots is 4, then 6 in patterns 2 and 4. This suggests that the number of horizontal dots increases by 1 in each pattern. This would mean pattern 1 would have 3 total horizontal dots and 1 total vertical dot. It will look like one row of 3 dots.

Pattern 3 will have 5 total horizontal dots and 3 total vertical dots. The sequence of patterns will look like the attachment.

__

b) The total number of dots in each pattern is 2×(pattern number) +1. Then the number of dots in Pattern 7 will be 2×7 +1 = 15 dots.

• Rewrite equation 1
3x + 6y = 27

• Write both equations
3x + 6y = 27
3x - 6y = -15

• Subtract equation 1 from equation 2
3x + 6y = 27

Combine like terms:

Subtract 8.8 from both sides of the equation:

2.5s + 8.8 - 8.8 = 14.8 - 8.8

steps below

Step-by-step explanation:

10 = -2.5 + ((0.02*RL + 2.5) / 625)*(625+500)

0.02*RL + 2.5 = (10+2.5)*625 / (625+500)

                         = 12.5*625 / 1125

Step-by-step explanation:

Step-by-step explanation:

A relation is any set of ordered pairs, which can be thought of as (input, output).

A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).

First row:

Months (input) and Days (output) = not a function. The month of February has two corresponding outputs: Days of 28 and 29.

{(13, 33), (17, 25), (22, 22), (25, 17), (33, 17)} = this relation is a function. Each input value (x-coordinate) corresponds to exactly one output value (y-coordinate).

Plot of Distance (mi) vs. Time (h): the graph represents a function. Each input value (x-coordinate) corresponds to exactly one output value (y-coordinate).

Second row:

{(1, 2), (5, 2), (5, 4), (7, 6), (11, 6), (11, 8)}: this relation is not a function. The input value of 5 has two corresponding output values: 2 and 4. The same goes with the input value of 11, which has two output values of 6 and 8.

Table of Age (x) and Shoe Size (y): does not represent a function. The x = 15 has two corresponding y-values: 10 and 10.5.

Diagram of x and y (bottom-left corner): this relation represents a function. Each input value corresponds to exactly one output value.
