We have c(t) = 350t and b(c) = 12c
The composite function that expresses the calories as function of time is given by
b[c(t)] = 12[350t]
b[c(t)] = 420t
Correct answer: B
Answer:
angle one:100 degrees
angle two:70 degrees
Step-by-step explanation: so angle two and the angle with 70 degrees are alternate angles, so they would be the same. at this point if you subtracted 70 from 180 because angle b is 180 degrees, you would get 110, so then you would have three angles, and it wouldn't be too hard to find the fourth, which is 100 degrees.
Answer:good luck
Step-by-step explanation:
You would have to use the matrices option on the calculator, clearly defining your variables. (Also arrange them so that the variables are in the same exact spot in equation equations; i.e. variables on the left side in a certain order and the answer on the right side)
Begin by clicking 2nd--> matrix (its in x⁻¹)--> edit --> [A] --> specify the size to be 3×4
Write out just the coefficient of each variable, all under a single column (for the specific variable).
The answer (or the number on the right side of the equation) would be the last box on the right.
Return back to the home screen with 2nd--> quit (under mode)
Click 2nd--> Matrix--> math --> B: rref( --> 2nd --> matrix--> names--> [A] --> enter.
Click enter to see the solution.
Hope I helped :)
Answer:
You don't really need to do it, but it helps you keep things more organized and easier to follow. Imagine if you're doing some multi-variable equation,
2a + 5b + 4d + 3c + b + a + 2d
that looks like a mess, it'll be easier to look at if you put all the similar variables next to each others like this:
a + 2a + b + 5b + 3c + 2d + 4d
(a + 2a) + (b + 5b) + 3c + (2d + 4d)
now you can add them up much easier.
