Answer:
f(2) = -2
Step-by-step explanation:
To solve this, you have to plug in 2 for x
f(2) = -2^2 + 2(2) - 10
= 4 + 4 - 10
= 8 - 10
= -2
Answer:
![RP=11.2\ ft](https://tex.z-dn.net/?f=RP%3D11.2%5C%20ft)
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
In this problem
![\frac{RP}{CA}=\frac{QR}{BC}](https://tex.z-dn.net/?f=%5Cfrac%7BRP%7D%7BCA%7D%3D%5Cfrac%7BQR%7D%7BBC%7D)
substitute the given values
![\frac{RP}{16.8}=\frac{14}{21}](https://tex.z-dn.net/?f=%5Cfrac%7BRP%7D%7B16.8%7D%3D%5Cfrac%7B14%7D%7B21%7D)
solve for RP
![RP=\frac{14}{21}(16.8)](https://tex.z-dn.net/?f=RP%3D%5Cfrac%7B14%7D%7B21%7D%2816.8%29)
