Answer:
its blurry for me.
Step-by-step explanation:
This is the concept of density, volume and mass of different materials; To calculate for the volume of an aluminium material with density of 2.375 grams per cubic centimeter and a mass of 0.78 Kilogram we proceed as follows;
Density=mass/volume
making volume the subject we get;
volume=mass/density
thus;
mass=0.78 kg= 780 g
density=2.375 g/cm^3
Hence,
volume=780/2.375=328.421 cm^3
Answer:
(b) (18, 27), because the rate of change of the function is 4/3
Step-by-step explanation:
just took the test mah peeps;)
Answer:
8
Step-by-step explanation:
Let F be the primitive of f, i.e.
Then, we have
So, we have
![\displaystyle \int_0^5(2x-2)\;dx = \left[x^2-2x\right]_0^5 = 25-10=15](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cint_0%5E5%282x-2%29%5C%3Bdx%20%3D%20%5Cleft%5Bx%5E2-2x%5Cright%5D_0%5E5%20%3D%2025-10%3D15)
As for the sine, we can spare the integral: the sine is an odd function, which means that it is symmetrical with respect to the origin. Any odd function integrated over a symmetrical neighborhood of zero (i.e. any interval of the form [-n,n]) returns zero: by symmetry, there is an equal amount of positive and negative area. So, we have
