Please help. Find the volume of the composite shape

Answer:

Graph is below.

Step-by-step explanation:

The solutions of the equations are : x = [8 ± √ 40] / 4

Given,

Y=2x² - 8x+3

Now,

To get the solution of equation equate it to 0 .

2x² - 8x+3  = 0

By quadratic formula,

x = -b ± √ b² - 4ac/2a

Substitute the values in the formula,

x = [8 ± √ 64 - 4(2)(3)] / 2* 2

x = [8 ± √ 40] / 4

Now plot the points in the graph. The graph is attached below.

ANSWER : 1  17/28

Answer:

4838 total number of voters

Step-by-step explanation:

In a whole circle there 360°, in a straight line theres 180°.

180-110=70 first to break it down to find the degrees of women.

180+70=250° for women.

250°=3360

we need to find 110° of men

25°=336

times 4

100°=1344

divide by 10

10°=134.4 round down 134

1344+134=1478

Answer:

D. A 70° angle

Step-by-step explanation:

Since this is a protractor, this will not be measuring side lengths, so A and C are out. Answer B is wrong as well since the angle shown is an acute angle meaning it is less than 90°. This leaves us with answer D.

Add the two equations together. This cancels the x and gets us y=6

Then substitute y in more the first equation which gets us -8

Answer: y = 6 x = -8

Step-by-step explanation:

X+2Y=4

-X-Y=2

(Combine like terms)

Y= 6

Explanation:

1. You can either turn the fractions into decimals (1.75 and 0.125) or make the denominators the same (1 6/8 and 1/8)

2. multiplying 3/4 by the 2 to get the least common multiple, which in this case is 8. (3/4x2=6/8)

3. Divide the number of acres available (1 6/8) by the number of acres needed for each garden (1/8) to get the answer. (1 6/8÷1/8=14)

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

y-(-3*x+7)=0

STEP1:

Equation of a Straight Line

1.1 Solve y+3x-7  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on the Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y-axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  y+3x-7 = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 7/1 so this line "cuts" the y axis at y= 7.00000

 y-intercept = 7/1  =  7.00000

Calculate the X-Intercept :

When y = 0 the value of x is 7/3 Our line therefore "cuts" the x-axis at x= 2.33333

 x-intercept = 7/3  =  2.33333

Calculate the Slope :

The slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 7.000 and for x=2.000, the value of y is 1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 1.000 - 7.000 = -6.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -6.000/2.000 = -3.000

Geometric figure: Straight Line

Slope = -6.000/2.000 = -3.000

x-intercept = 7/3 = 2.33333

y-intercept = 7/1 = 7.00000

Answer: 16/3 or 5.333333

Step-by-step explanation:

1/3 is 0.3333333 so 0.3333333 + 5 is 5.333333

Answer:

1/3 + 5 = 16/3 or 5 1/3

Step-by-step explanation:

First we convert 5 to a equal fraction towards 1/3.

5 = 5/1 = 15/3

Then we add 15/3 and 1/3.

15/3 + 1/3 = 16/3.

16/3 = 5 1/3.

So, the answer is 16/3 or 5 1/3.

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

The problem would look like this: 3(6-2/3).

First of all you would have to multiply both 6 and 2/3 by 3, resulting in a new equation, 18/1 - 2/1. Then, you can proceed to subtract 2 from 18 and you get 16.
