Answer:
28 cm area
Step-by-step explanation:
Answer:
408 cm^3
Step-by-step explanation:
You have to find the volume of each object individually. You first find the volume of the sphere, so you input the radius, which is 3, into the equation which comes out to be 108 cm^3. You then have to find the volume of the cylinder, and since you have the diameter of the cylinder, and you need the radius, and the radius is half of the diameter, you would input 5 into the equation as the radius, since half of 10 is 5. That comes out to be 300 cm^3, so then you add the two volumes together, which is 408 cm^3
Community property of multiplication
We have the following function:
f (x) = 4 * ((81) ^ (1/3)) ^ x
We observed that:
(81) ^ (1/3) = 4.326748711> 1
Therefore the function grows as it increases and decreases as x decreases.
We have then:
Domain: all reals.
Range: all reals greater than zero.
Answer:
A) {x | x is a real number}; {y | y> 0}
Answer:
There would be 875 teachers.
Step-by-step explanation:
8/5 equals 1.6.
1400 students / 1.6 = 875 teachers.
To check your work: 1400 students / 875 teachers = 1.6, which is the same ratio as 8 to 5.
