Answer: 36
Step-by-step explanation:
K(x) = 2x^2 - 5x + 3
K(-3) = 2(-3)^2 - 5(-3) + 3
K(-3) = 2*9 + 15 + 3
K(-3) = 18+15+3
K(-3) = 36
The answer to this question is 224. This is an arithmetic series. The first term is with n = 1 into the summand which gives
2(1) + 1 = 3
The last term is with n = 14 into the summand which gives
2(14) + 1 = 29
There are a total of 14 - 1 + 1 = 14 terms in this arithmetic series.
The formula for sum of an arithmetic series is used to find the sum
S = n/2(first term + nth term) = 14/2(3+29) = 224
The answer to this question is 224.
Answer:
x = -10
y= 1
explanation:
x+y = -9
y = -9 - x
-2x -3 (-9 - x) = 17
-2x +27 +3x = 17
27 + x = 17
x = -10
y = -9 -(-10)
y= -9 + 10
y= 1
(This is just math i did real quick and didnt double check, tell me if its wrong please!)
Answer:
A) y=-1/2x+55
Step-by-step explanation:
We can clearly see a negative trend/association between the number of hot drinks sold on a given day and the low temperature of that day. Therefore, the slope of the best line of fit must be negative, eliminating D and E. Also, notice that when the low temperature is 0°F, the number of hot drinks sold is about 55, which is a good indicator of our y-intercept or constant, eliminating choice C. Because the best line of fit is not so steep, the slope will be closer to 0 if it's a negative trend. This eliminates choice B, making the correct answer A.
