-12.5 because 7pm to 10pm are 3 hours.
Which is 3 times -2.5 and it equals -7.5 plus -5 which is -12.5
Answer:
The dot product of (7,5) and (-5,4) is -15
Step-by-step explanation:
Given
(7,5) and (-5,4)
Required
Determine the dot product
Dot product is calculated using the following formula;
Let a = (7,5) and b = (-5,4);
The above formula becomes
Hence, the dot product of (7,5) and (-5,4) is -15
Since the equations are for absolute value this means any negative number used the answer would become positive, so to get the lowest value possible x would need to equal 0, which would eliminate the x variable from the equations.
Replace x with 0 and solve:
|5(0)^2 - 16| + |10(0) - 2|
Simplify:
|0 - 16| + |0 - 2|
|-16| + |-2|
Combine:
|-18|
Absolute Value = 18
Answer:
-4
Step-by-step explanation:
(4-2)³ = 8
so 8 - 3 x 4
is equal to -4
C) closest to 2/5.
2/3 is bigger than half 2/10 would be like less than 1/4
