Which is the graph of the function f(x) = 3x2 + 2x - 6?

Answer:

4 sets

Step-by-step explanation:

The number of sets can Javier do before practice is over is 4.

Given that, Javier's swim practice is 1 1/2 hours long. The team spends 1/6 of an hour stretching before they start their practice sets. If each practice set takes 1/ 3 of an hour.

We need to find how many sets can Javier do before practice is over.

The steps for adding and subtracting fractions are as follows:

Step 1: Make denominators the same

Step 2: Add/Subtract the numerators (keeping the denominator as same)

Step 3: Simplify the fraction

We can write 1 1/2 as 3/2

Now, the number of hours left after stretching =  3/2 - 1/6

=9/6 - 1/6

=8/6

=4/3

So, number of sets = 4/3 ÷ 1/3

= 4/3 × 3/1

=4

Therefore, the number of sets can Javier do before practice is over is 4.

Answer:

I think it is B. 30 degrees

Step-by-step explanation:

Because if ZUY is 90 degrees and half of 90 degrees is 45 degrees but TUZ is a little bit less than the middle part of ZUY it has to be less than 45 degrees by a little bit and the only option would be 30 degrees. Hope this helped (:

The hamburgers and cheeseburgers sold on Sunday will be 275 and 340, respectively.

Given that:

H + C = 615           ...(1)

C = H + 65            ...(2)

From equations (1) and (2), then we have

H + H + 65 = 615

2H = 550

H = 275

Then the value of cheeseburgers (C) is calculated as,

C = 275 + 65

C = 340

The hamburgers and cheeseburgers sold on Sunday will be 275 and 340, respectively.

s= (-3, 10)

Step-by-step explanation:

x= 0-3=-3

y=5+5=10

The equation that represents the line will be y = (4/3)x. And the two points on the line will be (0, 0) and (3, 4).

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).

Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

From the graph, the line is passing through (0, 0) and (3, 4). Then the equation of the line is given as,

(y - 0) = [(4 - 0) / (3 - 0)](x - 0)

Simplify the equation, then we have

(y - 0) = [(4 - 0) / (3 - 0)](x - 0)

y = (4/3)x

Step-by-step explanation:

Answer:

7 is the answer. If a number can be divided by 36 then it can also be divided by 12 which is 3*12 therefor the remainder will be 19-12 which is 7. When 19 is divided by 36, the remainder is 19 and so 19 must be a number. When 19 is divided by 12 the remainder is 7.

Answer: 1/2

Step-by-step explanation:

First convert the equation into slope-intercept form.

-10 + x -2y = 0

+10               +10

 x - 2y = 10

-x             -x

-2y = 10 - x   Divide both sides by -2

y = 1/2x - 5

In this case the slope is 1/2  and the slopes parallel lines are the same but they must have different y intercepts.  Meaning that the slope of the other line will be 1/2.

Answer: (1500.66,1599.34)

Step-by-step explanation:

Confidence interval for population mean:

[tex]\overline{x}\pm z^*\dfrac{\sigma}{\sqrt{n}}[/tex]

,where [tex]\overline{x}[/tex] = Sample mean , n= Sample size, z* = critical two tailed z-value , [tex]\sigma[/tex] = population standard deviation.

As per given , we have

n= 16

[tex]\sigma = 154[/tex] square feet

[tex]\overline{x}= 1550[/tex] square feet

[tex]\alpha= 1-0.80 = 0.20[/tex]

Critical z-value = [tex]z_{\alpha/2}=z_{0.2/2}=z_{0.1}=1.2815[/tex]

Confidence interval for population mean:

[tex]1550\pm (1.2815)\dfrac{154}{\sqrt{16}}\\\\ = 1550\pm (1.2815)\dfrac{154}{4}\\\\= 1550\pm 49.33775\\\\ =(1550-49.33775,\ 1550+49.33775)\\\\\approx (1500.66,\ 1599.34)[/tex]

Answer: D

Step-by-step explanation:

To find the inverse, you switch x with y and y with x. Then, you solve for y.

y=4x         [switch y with x and x with y]

x=4y         [divide both sides by 4]

y=x/4

Now, we know the answer is D.
