H(x) = x2 + 1 k(x) = x – 2 (h + k)(2) = (h – k)(3) = Evaluate 3h(2) + 2k(3) =

matrenka [14]

For this case we have the following functions:

$h (x) = x ^ 2 + 1$

$k (x) = x - 2$

We must perform each of the operations shown.

We have then:

For (h + k) (2):

$(h + k) (x) = h (x) + k (x)$

$(h + k) (x) = (x ^ 2 + 1) + (x - 2)$

$(h + k) (x) = x ^ 2 + x - 1$

Evaluating for x = 2 we have:

$(h + k) (2) = 2 ^ 2 + 2 - 1$

$(h + k) (2) = 4 + 2 - 1$

$(h + k) (2) = 5$

For (h - k) (3):

$(h - k) (x) = h (x) -k (x)$

$(h - k) (x) = (x ^ 2 + 1) - (x - 2)$

$(h - k) (x) = x ^ 2 - x + 3$

Evaluating for x = 3 we have:

$(h - k) (3) = 3 ^ 2 - 3 + 3$

$(h - k) (3) = 9 - 3 + 3$

$(h - k) (3) = 9$

For 3h (2) + 2k (3):

$3h (2) + 2k (3) = 3 (2 ^ 2 + 1) + 2 (3 - 2)$

$3h (2) + 2k (3) = 3 (5) + 2 (1)$

$3h (2) + 2k (3) = 15 + 2$

$3h (2) + 2k (3) = 17$

Answer:

$(h + k) (2) = 5$

$(h - k) (3) = 9$

$3h (2) + 2k (3) = 17$

Find the probability of rolling a number greater than 2 and then rolling a multiple of 3 when a number cube is rolled twice. Ent

EleoNora [17]

The probability of number greater than 2:
4/6 = 2/3
The probability of rolling a multiple of 3:
2/6 = 1/3
Probability of both events happening:
1/2 x 1/3
= 1/6
