Answer:
When did Mary and Wyatt meet? 0.5 minutes later
How far from point Q did they meet? 3.5 km
Step-by-step explanation:
Mary’s motion is represented by d = 8t----(1)
Wyatt’s motion is represented by 2d + 14t = 15----(2)
We solve for d in equation (2) to get:d=7.5-7t----(3)
We equate equation (1) and (3) to get:
We now solve for t to get:
Now put t=0.5 into equation (1) to get d=0.5*8=4
This means they met 4 km from point P.
Therefore they meet 7.5-4=3.5km from point Q
4.54%, I hope I helped (:
Answer:
see below
Step-by-step explanation:
A can is a cylinder
V = pi r^2 h
The diameter is 6.4 we want the radius
r = d/2 = 6.4/2 = 3.2
V = 3.14 * (3.2)^ * 12.3
V =395.48928 cm^3
1 cm^3 = 1ml
V = 395.48928 mL
A can of soda has 355 mL
We are over estimating because the can narrows on the ends and the height is actually shorter because the ends do not have volume but are metal to contain the soda. We also did not take into account the curve in the bottom of a can of soda.
Answer:
Explanation:
The <em>end behavior</em> of a <em>rational function</em> is the limit of the function as x approaches negative infinity and infinity.
Note that the the values of even functions are the same for ± x. That implies that their limits for ± ∞ are equal.
The limits of the quadratic function of general form as x approaches negative infinity or infinity, when is positive, are infinity.
That is because as the absolute value of x gets bigger y becomes bigger too.
In mathematical symbols, that is:
Hence, the graphs of any quadratic function with positive coefficient of the quadratic term will have the same end behavior as the graph of y = 3x².
Two examples are:
