Answer:
9
Step-by-step explanation:
plug in t=2 into equation
so
13-2(2)
=13-4
=9
This is easy all you have to do is use the formula of the volume which is v=l.h.w
(X+9)(x+4)(x+5)= v
(X+9)(x^2+9x+20)
X^3+18x^2+101x+180=v
Answer:
Step-by-step explanation:
The formula for the area of a sector is
where theta is the measure of the central angle (which is the same measure as that of the arc that is intercepted by the 2 radii formig the angle), and r is the radius.
For us, theta is 90 degrees and r is 20. Filling in the formula:
which simplifies down a bit to
so
A = 314 m squared
Answer:
yes
Step-by-step explanation:
If you are dividing it will become 1 because 10 minus 10 equals 0. Anything to the power of 0 is 1 then you keep the base which is y so the answer is y
If you are multipling the answer will be y^10 because 10 plus 10 is 20 and you keep the base which is y
Answer:
3i + 63j
Step-by-step explanation:
Step 1: Replace the variables with the given statements
5(3i+9j) - 3(4i-6j)
Step 2: Distribute
15i + 45j -12i + 18j
Step 3: Combine like terms
3i + 63j
