The value of the length DF is 17
<h3>How to determine the length DF?</h3>
The statement Triangle ABC = Triangle ADF means that the triangles ABC and ADF are congruent triangles.
So, we have:
AB = AD
AC = A F
BC = DF
Given that BC = 17;
The equation BC = DF becomes
17 = DF
Rewrite as:
DF = 17
Hence, the value of the length DF is 17

Answer:
B
Step-by-step explanation:
Given the line of best fit
y = - 9.21x + 168.7
Substitute the weight of the pumpkin , that is x = 5, into the equation.
y = - 9.21(5) + 168.7
= - 46.05 + 168.7
= 122.65 ≈ 123 feet ( to the nearest foot )
The answer should be obtuse. I'm not sure why it is saying it's incorrect but none of the other answers make sense.
Answer:
-5
Step-by-step explanation:
or, f(x) = -x^2+10x+16
or, f(7) = (-7)^2+10*-7+16 (-7*-7=49)
=49-70+16
=65-70
=-5
