The Graph is shown below

Step-by-step explanation:

The Graph of a Function

Given the function:

[tex]\displaystyle y=g(x)=-\frac{3}{2}(x-2)^2[/tex]

It's required to plot the graph of g(x). Let's give x some values:

x={-2,0,2,4,6}

And calculate the values of y:

[tex]\displaystyle y=g(-2)=-\frac{3}{2}(-2-2)^2=-\frac{3}{2}(-4)^2==-\frac{3}{2}*16=-24[/tex]

Point (-2,-24)

[tex]\displaystyle y=g(0)=-\frac{3}{2}(0-2)^2=-\frac{3}{2}(-2)^2=-\frac{3}{2}*4=-6[/tex]

Point (0,-6)

[tex]\displaystyle y=g(2)=-\frac{3}{2}(2-2)^2=-\frac{3}{2}(0)^2=0[/tex]

Point (2,0)

[tex]\displaystyle y=g(4)=-\frac{3}{2}(4-2)^2=-\frac{3}{2}(2)^2=-\frac{3}{2}*4=-6[/tex]

Point (4,-6)

[tex]\displaystyle y=g(6)=-\frac{3}{2}(6-2)^2=-\frac{3}{2}(4)^2=-\frac{3}{2}*16=-24[/tex]

Point (6,-24)

Answer:

Darlene bought more fabric

Darlene bought 3.4 yards more

Step-by-step explanation:

Darlene = 7 yards + 20% extra

= 7 yards + (20% of 7 yards)

= 7 + (20% × 7)

= 7 + (0.2 × 7)

= 7 + 1.4

= 8.4 yards

Chris = 4 yards + 25% of 4 yards

= 4 yards + (25% of 4 yards)

= 4 + (25% × 4)

= 4 + (0.25 × 4)

= 4 + 1

= 5 yards

Darlene bought more fabric

How much more?

Darlene - Chris

= 8.4 yards - 5 yards

= 3.4 yards

Darlene bought 3.4 yards more

Answer:

17/25

Step-by-step explanation:

The required total score for 100% mark is given as 25.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Let the x be the be score for 100% marks.
68% of x = 17
x = 17 / 68%
x = 25

Thus, the required total score for 100% mark is given as 25.

Find the Slope

(−1, −2) , (3, −1)

Slope is equal to the change in y over the change in x, or rise over run.

     change in y

m =  ---------------

    change in x

The change in x is equal to the difference in x-coordinates (also called run), and the change in y

is equal to the difference in y-coordinates (also called r ise).

     y2 − y1

m =  -----------

     x2 − x1

Substitute in the values of x and y into the equation to find the s lope.

       m = −1 − (−2) /3 − (−1)

Simplify the numerator.

Multiply −1 by −2.

       m =  −1 + 2 /3 − (−1)

Add −1 and 2.

       m =  1/3 − (−1)

Simplify the denominator.

Multiply −1 by −1.

       m = 1/3 + 1  

Add 3 and 1.

        m =  1/4

Answer: 52%

Step-by-step explanation:

The team batted 250 times. In that time, they got 60 strikeouts, 50 flyouts and 20 groundouts.

The total number of out they got was therefore:

= 60 + 50 + 20

= 130 outs

The percent of the time they got outs out of the total is:

= 130/250

= 52%

Answer:

140

Step-by-step explanation:

The two non supplementary angles not supplementary to x = the sum of those two angles. So the sum = 57 + 83 = 140

x = 140

Answer:

147.395348837

Step-by-step explanation:

6338 divided by 43 gives a quotient of 147 with a remainder of 17.

When dividing 6338 by 43 with remainder, we can perform long division to find the quotient and remainder.

Start by dividing the first digit of the dividend (6) by the divisor (43). The quotient is 0 since 6 is less than 43.

Bring down the next digit of the dividend, which is 3, to the right of the 0. We now have 63.

Divide 63 by 43. The quotient is 1, as 43 goes into 63 once.

Multiply the divisor (43) by the quotient (1) and subtract the result from 63:

63 - (43 x 1) = 63 - 43 = 20

Bring down the next digit of the dividend, which is 3, to the right of the 20. We now have 203.

Divide 203 by 43. The quotient is 4, as 43 goes into 203 four times.

The final remainder is 17.

Therefore, 6338 divided by 43 gives a quotient of 147 with a remainder of 17.

Answer:

the width is (x + 4) and the length is (x + 10)

Step-by-step explanation:

The area of a rectangle is given by A = L * W, where L is the length and W the width.  

If we factor the given x^2 + 14x + 40, we get (x + 10)(x + 4).  Thus, the width is (x + 4) and the length is (x + 10).

Answer: 7 errands

Step-by-step explanation:

The amount that he needs is:

= 30 - 10.50

For every errand he runs, he makes $3. The number of errands needed to get to $30 is:

= 19.50/3

= 6.5

Answer: -4x + y = 5 in slope intercept form is 4x + 5

Answer: y= 4x + 5

Step-by-step explanation:

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y = mx + b

Rewrite in slope-intercept form.

Add 4x to both sides of the equation.

y = 5 + 4x

Reorder 5 and 4x.

y= 4x + 5
