What is the volume of a prism with the length (x+9) width (x+5) and (x+4)?<br> Please Help
IrinaVladis [17]
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

It says to calculate the area of the sector and t round to the nearest hundredth and to use 3.14 for Pi
fenix001 [56]

Answer:

Step-by-step explanation:

The formula for the area of a sector is

A=\frac{\theta}{360}*\pi r^2 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:

A=\frac{90}{360}*(3.14)(20)^2 which simplifies down a bit to

A=\frac{1256}{4} so

A = 314 m squared

Would y^10/y^10 become 1?
mote1985 [20]

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
