Answer:
-503
Step-by-step explanation:
the statement tell us:
(r - 5)^3 + r^2
r= -3
so we have:
(-3 - 5)^3 + (-3)^2
(-8)^3 + 9
-512+9 = -503
Answer:
WHEN YOU
Step-by-step explanation:
WHEN YOU MULTIPLY 1X1 YOU GET ONE
Answer:
9
Step-by-step explanation:
Because line PQ and line PR are both tangent to circle S, it would result in them being equal. So first to find PQ, you would have to find the value of variable x. To do this you would set both equations equal to each other and solve
6x - 9 = 2x + 3
-2x -2x
4x - 9 = 3
+9 +9
4x = 12
x = 3
Now you have to substitute 3 back into the equation for PQ:
6(3) - 9
18 - 9
= 9
Resulting in PQ = 9, to check your answer, take the value of x (3) and substitute it into PR and you should also get 9
2(3) + 3
6 + 3
= 9
They traveled approximately 165 miles.The speed is not constant so it is not the exact number.
Answer: D. .400
Step-by-step explanation:
Given : In a multiple regression model involving 44 observations, the following estimated regression equation was obtained.

For this model,
Regression sum of squares =SSR = 600
and Sum of squares due to error =SSE = 400.
Total sum of squares = SST= SSR+SSE
SST= 600+400=1000
The multiple coefficient of determination is given by :-

Substitute values , we get


Thus, the multiple coefficient of determination for the above model is 
Hence, the correct answer is D. .400.
