What is the domain of the square root function graphed below?
hodyreva [135]
Since x is never less than -4 but is equal to it at one point and is less than 0 in some points, the only possible answer and the correct answer is x ≥ -4.
So the domain to this graph is x ≥ -4.

For this problem, assume Gwen and Harry have 5 types of cones and 9 flavors of ice cream.
ohaa [14]

Answer: Hello!

In this problem you can chose 3 options:

the type of cone, the first flavour, and the second flavour.

a) In how many different ways can your order one cone and two scoops of ice cream?

You have 5 options for cones, 9 options for the first ball of ice cream, and 9 options for the second ball of ice cream (because you can repeat flavour) then the total number of combinations is the product of this 3 numbers, this is:

5*9*9 = 405 combinations

b) Here we cant order the same flavour of ice cream, then:

we still have 5 options for cones, 9 options for the first ball of ice cream, and this time 8 options for the second ball ( because we need to remove the flavour that we picked in the first ball of ice cream) then the number of combinations is:

5*9*8 = 360 combinations.

A cylinder has a diameter of 40 feet and a height of 32 feet. What is the surface area of the cylinder? Express the answer in
mafiozo [28]

Answer:

6524.51 ft^2

Step-by-step explanation:

The surface area of a cylinder is given as;

SA = 2\pi rh + 2\pi r^2

where r = radius

h = height

The cylinder has a height of 32 feet and a diameter of 40 feet. This means that the radius is:

40 / 2 = 20 feet

The surface area is therefore:

SA = (2*\pi* 20 * 32) + (2*\pi *20^2)\\\\SA = 4021.24 + 2513.27\\\\SA = 6524.51 ft^2

The surface area of the cylinder is 6524.51 ft^2.
