Answer:
B) -0.4 seconds
Step-by-step explanation:
Laps: 25
Goal: -10 seconds to all 25 laps combined (10 seconds difference => -10)
divide by total laps
-10 /25 = -0.4s difference each lap
Answer: B
Step-by-step explanation:
If an absolute value of a negative number plus a absolute value of the positive number is positive. Absolute value of anything is positive.
Answer:
92
Step-by-step explanation:
Lab Scores are 84, 81, and 93
Test Scores are 89 and 94
Each lab counts once and each test counts as two labs. At the end of the semester there is a final lab that counts as three regular labs.
Total Number of Labs= (3X1)+(2X2)+(1X3) =3+4+3 =10
To recieve an A(90), the average of her scores must be 90.
Let her final lab score =b
Refer to the attached diagram
Total Score=624+3b
For her average =90
![\frac{624+3b}{10}=90](https://tex.z-dn.net/?f=%5Cfrac%7B624%2B3b%7D%7B10%7D%3D90)
Cross multiplying
624+3b =90 X 10
624+3b =900
3b =900-624
3b =276
Dividing both sides by 3
b= 92
She must score 92 in her final lab to receive an A.
Answer: (X-3)^4
Step-by-step explanation:
To shift a function left, add inside the function's argument: f (x + b) gives f (x)shifted b units to the left. Shifting to the right works the same way; f (x – b) is f (x) shifted b units to the right.
Therefore, the equation is ![F(x) = G(x-3) = (X-3)^4](https://tex.z-dn.net/?f=F%28x%29%20%3D%20G%28x-3%29%20%3D%20%28X-3%29%5E4)
If the temperature drops, then you must have subtract amount of drop from initial temperature.
![-12,3^o-6,8^o=-(12,3^o+6,8^o)=-19,1^o](https://tex.z-dn.net/?f=-12%2C3%5Eo-6%2C8%5Eo%3D-%2812%2C3%5Eo%2B6%2C8%5Eo%29%3D-19%2C1%5Eo)
The correct answer is the first one.
