Suppose the graph of y= x^2 translated left 2 units, and up 8 units
Elis [28]

Start with y = x2

 

Shift 2 units left to get y = (x+2)2

 

Vertically stretch to get y = 6(x+2)2

 

Reflect across x-axis to get y = -6(x+2)2

 

Shift 7 units down to get y = -6(x+2)2 - 7

hope this helps!

Explain how place value could be used to find the difference of 4.23 and 2.75
seropon [69]
You can use place value to align the numbers together so you can subtract correctly. Match the ones, tenths, and hundredths digits together to subtract.

4.23
2.75

The radius of a circle is 6. Using T, which equation expresses the ratio of the circumference of the circle to the circle's diam
Liono4ka [1.6K]

Answer:

Option (B)

Step-by-step explanation:

The given question is incomplete; here is the complete question.

The radius of a circle is 6. Using π, which equation expresses the ratio of the circumference of the circle to the circle's diameter?

A) C/6 = π

B) C/12= π

C) C = 6πr

D) C = 12πr

Formula to get the circumference of the circle is,

C = 2πr = π × D

Where C = circumference of the circle

D = Diameter of the circle

By dividing with D on both the sides of the formula,

\frac{\text{C}}{\text{D}}=\pi

Since, diameter 'D' = 2r,

\frac{\text{C}}{\text{2r}}=\pi

\frac{\text{C}}{2\times 6}=\pi

\frac{\text{C}}{12}=\pi

Therefore, equation given in Option (B) will be the correct expression.

Find the volume of the composite figure. please!
Irina-Kira [14]
Volume= Length * width ( aka Base ) * height 

Break up the figure into easier figures, a small square and a bigger square.

Small square- 3*2*1 = 6 cm

Large Square- 7*6*1 = 42 cm

42 + 6 = 48 cm. But wait! You have to take one more step, which is minus-ing 6 from 48. Why? Notice that there is a little area where a side of the small square meets the bigger square. That little area is worth 3 cm ( length is 3, height is 1 cm ) times 2 ( 3 cm is one side, another 3 cm is the other side from the other square ) = 6 cm.

Your total answer should be 42. ( or 48, if your teacher doesn't count the area where the squares meet/join together ).
