Answer:
Step-by-step explanation:
For Mia:
distance,d = 100 yard
time, t = 2 min 33 sec = 153 s
Speed = distance / time
speed = 100 / 153 = 0.65 yard/s
For Larisa:
distance, d = 350 yard
time, t = 5 min 18 sec = 318 s
speed = 350 / 318 = 1.1 yard/s
So, the speed of Larisa is more than the speed of Mia.
Answer:
x^2 + 10x - 13y.
Step-by-step explanation:
3(2x + y) + 4(x - 4y) + x^2 First apply the Distributive law to the parentheses:
= 6x + 3y + 4x - 16y + x^2 Now add like terms:
= 10x - 13y + x^2.
Answer:
no solution
Step-by-step explanation:
2x-5=8x+7-6x
2x-5=2x+7
-5=7
Not true so no solution
The derivative is the rate of change of a function, basically represents the slope at different points. To find the derivative of the given function you can use the power rule, which means, if n is a real number, d/dx(x^n)= nx^(n-1). This is a simplification of the chain rule based on the fact that d/dx(x)=1. Anyway, this means that d/dx(x^3 + 1)= 3x^2. Here n is 3 and so it is 3*x^(3-1)= 3x^2. The derivative of x^3+1 is 3x^2.
If you are wondering what happened to the 1, for any constant C, d/dx(C)=0.
