5. ERROR ANALYSIS Describe and correct the error in finding the sum of the number

Mathematics
1 answer:
Semmy [17]3 years ago
8 0

Answer:

  (25 × 10") + 153 × 10" = (25 +153) × 10" = 178 × 10" = 1780"

Step-by-step explanation:

a) Numbers are miscopied: the numbers in parentheses should be (25 +153). Of course, the sum of these should be 178, not 78.

b) The common factor 10" is somehow expanded to 110' x 10°. It should be 10".

The sum should be ...

  (25 × 10") + 153 × 10" = (25 +153) × 10"

  = 178 × 10" = 1780" . . . . . correct sum

_____

Maybe the middle step is an attempt to convert to feet.

  1780" × (1')/(12") = (148 1/3)' = 148' 4"

A quadtratic equation that has x intercepts of -8,0 and 2,0 and has a vertical stretch of 3
Paladinen [302]

Answer:

f(x) = 3(x + 8)(x - 2)

Step-by-step explanation:

The intercept form of a quadratic function is y = a(x - r)(x - s), where r and s are the x-intercepts and a is the vertical stretch/compression factor.

If the intercepts are at (-8, 0) and (2, 0), and the vertical stretch is 3, just substitute these values into the intercept form formula, and you're done!

Decide whether or not the figures are similar. Explain why or why not.
AleksAgata [21]

Step-by-step explanation:

To tell if JKON and JKLM are similar, compare the ratios between corresponding sides.  For example:

JK / KO = 5/8

JK / KL = 5/22

The ratios aren't the same, so the shapes aren't similar.
