First of all, you need to understand what the transformations are.
Transformation 1 is a translation right 4 units and up 4 units.
Transormation 2 is a dilation by a factor of 4.
After you understand the transformations, you are in a position to evaluate the statements about them.
a. FALSE. The image will have the same area as the original.
b. FALSE. The image may be moved, but it is moved by dilation about the origin. It is not translated.
c. FALSE. Every vertex will be moved by 4 units up and right.
d. TRUE. Dilation by a factor of 4 makes every linear measure 4 times what it was. The perimeter will be 4 times that of the original figure.
They made an error in step 2 which showed up in step 3. When adding those numbers, Dan should have gotten $223.45 and not $241.95
Answer:
1/6 or 0.16666... can be written rounding off to three decimal digits such as:
- (rounding off to three decimal digits)
Step-by-step explanation:
As we know that
In order to round off three decimal places (or digits ), we need to check:
- the digit in the fourth place.
- If the digit in the fourth place is greater than 5, then we must add 1 to the previous digit.
Therefore, 1/6 or 0.16666... can be written rounding off to three decimal digits such as:
- (rounding off to three decimal digits)
Answer:
20 ft
Step-by-step explanation:
The formula for the surface area of a pyramid is often written in terms of the base dimensions and the slant height. We can solve that formula for the slant height.
SA = base area + lateral area
SA = b² + 2bs . . . . . where b is the base dimension, and s is the slant height
SA -b² = 2bs . . . . . subtract the base area
s = (SA -b²)/(2b) . . . . divide by the coefficient of s
Using the given values for surface area and base length, we find ...
s = (896 -16²)/(2·16) = 640/32 = 20 . . . feet
The slant height of the pyramid is 20 feet.
