Answer:
28:35
Step-by-step explanation:
Since Rita is trying to prove that the two triangles are similar, she will be looking for corresponding sets of sides that have an equivalent ratio. Therefore, since for the big triangle she uses sides PQ and PR, the corresponding sides on the smaller triangle would be PS and PT, which have a ratio of 28:35. Hope this helps!
Answer:
see explanation
Step-by-step explanation:
Expand the right side and then compare like terms with the left side.
(q + 2
)²
= q² + 4q + 12
= q² + 12 + 4q
Compare like terms with 28 + p
Comparing the terms gives
p = 4q
and comparing the constant terms gives
q² + 12 = 28 ( subtract 12 from both sides )
q² = 16 ( take the square root of both sides )
q = ± 
= ± 4
Hence
p = 4q = 4 × ± 4 = ± 16
The slope is 5/-8
Since rise/run...
Rise = +5 and Run = -8
First you have to flip the second fraction
For a function to have a derivative in a point has to be continuous at the point, that is, it has to be defined at that point, other wise the derivative would be meaningless.
