Answer 1

Equation:

j(x) = -3x² - 5

Which part of the equation tell us that the graph opens downward?

Solution:

Here see that the leading coefficient of x² which is (-3) is less than 0, meaning negative. a < 0 Hence, the graph will open from downwards.

Answer 2

Answer:

The coefficient of x²

Step-by-step explanation:

The part of the function j(x) which shows the graph opens downward is the coefficient of x². Depending on whether the value is positive or negative, we will understand if it opens upward or downward.

The scatter plot shows the profit by the month for a new company during its first year of operation. Which equation most closely models the line of best fit for the scatter plot? A) y = 5x B) y = 2.5x C) y = 5x + 1000 D) y = 2.5x + 1000

Answers

The equation most closely models the line of best fit for the scatter plot is y = 2.5x

Equation of a line

A line is the distance between two points. The equation of a line in point-slope form is given as y =mx + b

where:

m is the slope or rate of change

b is the intercept

Using the coordinate points on the line (3, 5000) and (9, 20000)

Get the rate change(slope)

Slope = 20000-5000/9-3

Slope = 15000/6 = 2500

Determine the y-intercept by substituting

5000 = 2500(3) + b

b = 5000 - 7500

b = -2500

Determine the equation

y = 2.5x - 2.5

Hence the equation most closely models the line of best fit for the scatter plot is y = 2.5x

Multiply. 3√⋅22√⋅58√⋅18−−√ Enter the expression in the box in simplified radical form.

Answers

The value of multiplying the factors of 3√2 * 2√5 * 8√18 is 288√5 in radical form

How to multiply the expression?

The expression is given as:

3√2 * 2√5 * 8√18

Multiply the integers

3√2 * 2√5 * 8√18 = 3 * 2 * 8 *√2 *√5 * √18

This gives

3√2 * 2√5 * 8√18 = 48 *√2 *√5 * √18

Multiply the radicands

3√2 * 2√5 * 8√18 = 48 *√5 * √36

Take the square root of 36

3√2 * 2√5 * 8√18 = 48 *√5 * 6

Multiply 48 by 6

3√2 * 2√5 * 8√18 = 288√5

Hence, the value of 3√2 * 2√5 * 8√18 is 288√5

Mallory wants to buy a new window air conditioning unit. The cost for the unit is $329.99. If she plans to run the unit three months out of the year for an annual operating cost of $108.78, which function models the cost per year over the lifetime of the unit, C(n), in terms of the number of years, n, that she owns the air conditioner?

Answers

The function (329.99 + 108.78n)/n will represent the cost per year over the lifetime of the unit in terms of the number of years.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have:

Cost for the unit = $329.99

Annual operating cost = $108.78

C(n) represents the cost per year

n represents the number of years

The function can be modelled:

C(n) = (329.99 + 108.78n)/n

Thus, the function (329.99 + 108.78n)/n will represent the cost per year over the lifetime of the unit in terms of the number of years.

Answer:

424

Step-by-step explanation:

To find the surface area, you need to find the area of all the faces of the shape. Because this is a rectangle, you only need to find the 3 different faces and then multiply them by 2. For the largest face, the dimensions are 8*15, which is 120. Multiply that by 2 and you get 240. For the long, slim face, the dimensions are 4*15, which is 60. Multiply that by 2 and you get 120. Finally, the smallest face's dimensions is 8*4, which is 32. Double that and you get 64. Now all you need to do is add all the products up. 240+120+64 is 424, which is your answer.

[tex]nearest \: whole \: number = 590[/tex]

therefore, he can swim 590 meters in 15 minutes.

answer= option C

Answer:

C: 590 meters

Step-by-step explanation:

Let's start by finding Raymond's rate of swimming for meters per minute. We know that he can swim 236 meters in 6 minutes. So let's divide 236 by 6 to find how far Raymond can swim in 1 minute.

236 / 6 = 39.3

So if we know Raymond can swim 39.3 meters in 1 minute, we multiply 39.3 meters by 15, to find how far he can swim in 15 minutes.

39.3 * 15 = 589.995 which is approximately 590 meters. So, we would chose option C: 590.
