pychu [463]

Answer: There are 90 different schedules are possible for Molly Kay.

Step-by-step explanation:

Since we have given that

Three time scheduled at 8:00, 10:00, 11:00.

Number of courses offer at 8:00 = 5

Number of courses offer at 10:00 = 9

Number of courses offer at 11:00 = 2

So, the number of different schedules are possible for Molly Kay is given by

$^{5}C_1\times ^9C_1\times ^2C_1\\\\=5\times 9\times 2\\\\=45\times 2\\\\=90$

Hence, there are 90 different schedules are possible for Molly Kay.

Find the value of x. If necessary, round to the nearest tenth.

Ghella [55]

Answer:

x = 10.3 in

Step-by-step explanation:

To find the value of a, use the area formula for a triangle. The formula is A = 1/2 *b*h. Here b = x and h= x. The formula becomes A = 1/2 *x². Substitute A = 53 and solve for x by using inverse operations.

A = 1/2x²

53 = 1/2x²

106 = x²

√106 = x

10.3 = x

What is the value of g(2)?

n200080 [17]

Answer:

g(2)=1

Step-by-step explanation:

We need to use the second definition of the function since x=2

g(2) = 2^3 -9(2)^2 +27(2) -25

= 8-9(4) +54 -25

= 8-36+54-25

= 1
