The area of a triangle is 64 cm2. If the height of the triangle is 8cm, how many centimeters long is the base?
A. 8 cm
B. 16 cm
C. 20 cm

Answer:

18.58 cm

Step-by-step explanation:

8^2 - 6^2 = sqrt 28

sqrt 28 = 5.29

8 + 5.29 + 5.29 = 18.58

Answer:

Geometry, Trapezoid Calculator, Calculates Area, Diagonals, Angles, height, altitude, perimeter; ... both base lengths and the area. ... A trapezoid has bases that are 30 and 55 centimeters in length and the non-parallel sides (or legs) are 15 and 20 centimeters. ... The isosceles trapezoid has both legs of equal length.

Answer:

1. The graph is non-proportional because it starts from (0, 2).

2. The slope of the line is 3.

3. y=3x+2

Step-by-step explanation:

The graph is non-proportional since it didn't start from the origin (0, 0). If the graph starts from the origin, then it's proportional.

To find the slope of the line, use this equation, [tex]m=\frac{y2-x2}{y1-x1}[/tex] or [tex]\frac{rise}{run}[/tex] to solve for slope. Pick any two points on the line and use the equation that I mentioned to solve for slope m.

[tex]m=\frac{5-2}{1-0} =\frac{3}{1} =3[/tex]            I chose (0, 2) and (1, 5) to find the slope

Once you find the slope, write the equation in y=mx+b form to find what b is with one of the points given.

[tex]2=3(0)+b[/tex]

[tex]-0[/tex]   [tex]-0[/tex]

2 = b

Step-by-step explanation:

[tex]\sqrt[3]{1728} = 12[/tex]

12 x 12 x 12 = 1728

Answer:

576

Step-by-step explanation:

1728/3

17-15= 2

bring down the "2" and you get 22

Then you do 22-21= 1

bring down the "8"

Then you have 18-18=0

In the slope intercept form, the m is the slope and the b is the y-intercept.

Answer: A. Japan

Step-by-step explanation:

Japan would have more variables in the production the vehicles annual leave because it has the longest box out of all other reasons, and when you’re dealing with box equations the longest box has the most variables when the short box has the least variables.

Japan region has had the greatest amount of variability in annual vehicle production.

A box and whisker plot displays a "box" with its left edge at Q₁, right edge at Q₃, "center" at Q₂ (the median), and "whiskers" at the maximum and minimum.

More varied data is implied by larger boxes.

When comparing box plots, especially when the medians are comparable, that is something to keep an eye out for.

Whisker lengths and box sizes with wider ranges signify more varied data.

So, from the given choices,

Japan shows the greatest amount of variability.

Therefore, the Japan box plot is the required plot.

Answer:

$21,885.5

Step-by-step explanation:

84.5% of 25,900 =

0.845 * 25,900 =

21,885.5

Because it says that the car is on sale for 84.5% of it's original price means that that is the price of the car.

If it had said that the car was 84.5% off, we would have had to subtracted 21,885.5 from 25,900, however, it didn't so it's ok.

Hope that this helps, have a good day/night and good luck!

Answer:

a = -5

Step-by-step explanation:

a = 1/2(-10) + 3^2 - (-1) - 10

a = -5 + 3^2 - (-1) -10

a = -5 + 9 - (-1) - 10

a = 4 - (-1) - 10

a = 4 + 1 - 10

a = 5 - 10

a = -5

x = -1y = 3

z = -10

a = -5

Answer: b) |y-11|=6

               d) |a-0|=1/2

Step-by-step explanation:

In the number line its y for b) and a for d) not x

How to solve b):

The equation is |y-c|=d

y=5,x=17

find the midpoint between those numbers. (17+5)/2=11

c=11, c is always the midpoint of the equation

|y-11|=d

for d, substatute y, y=5, y=17

|5-11|=6

|17-11|=6

d=6, thus your answer |y-11|=6

How to solve d)

Same thing

equation = |a-c|=d

a=1/2,a=-1/2

the midpoint of 1/2 and -1/2=0

c=0, |a-0|=d

substitue a, |1/2-0|=1/2 , |-1/2-0|=1/2, thus your answer |a-0|=1/2

Answer:

f(x) = -(x-3)^2 + 4

Step-by-step explanation:

(h; k) are the coordinates of the vertex.

On the graph are (3, 4), therefore we have:

f(x) = a(x-3)^2 + 4

We have the x- intercept (1,0) -> x=1; y=0.

Substitute them into the equation:

0 = a(1 - 3)^2 + 4

0 = a(-2)^2 + 4

4a + 4 = 0 | -4

4a = -4   |-4

a = -1

So, we have the answer:

f(x) = -(x-3)^2 + 4
