It took Trina 1 hour and 30 minutes to shovel the snow from her neighbor’s driveway. During that time she burned 630 calories. How many calories per minute did Trina burn shoveling snow?

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

The first step to solve this problem is to convert 1h 30min into just minutes. since there are 60 minutes in 1 hour you take 60 and add it ot the 30 extra minutes to get a total of 90.

Now, this question is asking you to find how many calories per minute she burns. When you are asked to find ___ per___ all you have to do is divide the first number by the second one. In this case you will divide calories by minutes.

630/90=7

Round 8.54 to nearest tenth

Answers

If you look at the image below, you can find what the tenths place is.
Juts follow the rule: 5 or more raise the score, 4 or less stay and res(t)
Therefore 8.54 would raise to 8.5 Since the four is lower than five, it rounds down.
~Hope this helped :)

If the last number is less than 5, you will not round the number next to it, if the number is more than 5 or 5, you'll round
So the answer to this question is 8.5

Which of the following graphs described by the function given below y=3x^2+7x+2

Answers

Answer:

*Parabola that opens up

*y-intercept is 2

*x-intercepts are -1/3 and -2

*vertex is (-7/6 , -25/12)

Step-by-step explanation:

I will describe what this graph looks like.

First, the graph is quadratic because it is in the form ax² + bx + c. The function must be in the shape of a parabola. Parabolas look like a "U" shape.

Whether "a" is negative or positive represents of the parabola opens up or down. Since "3" is positive, the parabola opens up.

"c" represents the y-intercept. The y-intercept is when the graph touches the y-axis. The function must have a y-intercept of positive 2.

We can also find its x-intercepts, also called roots/zeroes, by substituting into the quadratic formula $x=\frac{-b±\sqrt{b^(2)-4ac } }{2a}$ (Ignore the Â).

Using the form ax² + bx + c, we know:

a=3; b=7; c=2

Substitute into the formula.

$x=\frac{-b±\sqrt{b^(2)-4ac } }{2a}$

$x=\frac{-7±\sqrt{7^(2)-4(3)(2) } }{2(3)}$

$x=(-7±√(25 ) )/(6)$

$x=(-7±5 )/(6)$

Split the equation at the ± sign.

$x=(-7+5 )/(6)$

$x=(-2)/(6)$

$x=-(1)/(3)$

$x=(-7-5 )/(6)$

$x=(-12 )/(6)$

$x=-2$

The graph has x-intercepts -2 and -1/3.

We can find the vertex of the graph. It is the part of the parabola that is the lowest (or highest, is it opens down).

Find the midpoint of the x-intercepts for the vertex x-coordinate:

(-1/3 - 2)/2 = (-1/3 - 6/3)/2 = (-7/3)*(1/2) = -7/6 = -1.167 = x

Substitute the vertex x-coordinate into the formula to find the "y" in vertex.

y=3x²+7x+2

y=3(-7/6)²+7(-7/6)+2

y= 147/36 + (-49/6) + 2

y= 147/36 + (-294/36) + 72/36

y= (147-294+72)/36

y = -75/36

y = -25/12 = -2.083

The vertex is (-7/6 , -25/12) OR about (-1.167, - 2.083).

Final answer:

The function $y=3x^2+7x+2$ represents a parabola. This is graphed by creating a series of (x,y) pairs and plotting them. The resultant shape is a parabola opening upwards.

Explanation:

The graph described by the function $y=3x^2+7x+2$ is a parabola as this is a quadratic function. To depict this graph, you plot specific points determined by varying the values of x and calculating the corresponding y values.

For instance, if x is 0, y would be 2 ( $since 3*0^2+7*0+2=2$ ), so (0,2) is one point on the graph. You continue this process with different x values to generate a series of (x,y) pairs, which you can then plot on a graph. Once you've plotted these points, you can connect them to see the graphical representation of the function.

In this case, you would get a parabola opening upwards since the coefficient of the $x^2$ term is positive.

Please help!!!!!!!!!!!!1) You have $20 in savings at the bank.Each week,you add $2 to your savings Let y represent the total amount of money you have saved at the end of x weeks.Write an equation to represent this situation, and identify the slope of the equation. What does that number represent?(aka interpret the slope)

Show ALL work!!!!!!!!!!!!!!!!!!! please help

Answers

$x-weeks\ny-total\ money\n2x-saving\ every\ week\n\n\boxed{y=2x+20}$

so at first you have 20
so
y= money saved so
so each week times 2 +20 =total because
you started with 20 then
x weeks times 2 gives you how much you earned so
y=2x+20
slope=2
(slope intercept form=y=mx+b where m=slope)
