Answer:

Increasing by 40%

Step-by-step explanation:

This is a exponentional function. The format for this type of function is a(b)^x. So "a" is your initial value, and "b" is the rate. Now let's think to ourselves what times what is still equal to the same thing? That is 1. But in our question, we have 1.4. So we are increasing by 0.4, or 40%.

Write the quadratic function in standard form

Murrr4er [49]

Answer:

B. f(x) = x² + 10x + 17

Step-by-step explanation:

Given:

f(x) = (x + 5)² - 8

Required:

Write in standard form

SOLUTION:

f(x) = (x + 5)² - 8

Expand (x + 5)²

f(x) = (x + 5)(x + 5) - 8

f(x) = x(x + 5) +5(x + 5) - 8

f(x) = x² + 5x + 5x + 25 - 8

Add like terms

f(x) = x² + 10x + 17

P(A and B)=P(A)•P(B) is used when two events are used when two events are

Natali [406]

Answer:

Independent.

Step-by-step explanation:

Independent events:

Two events, A and B, are said to be independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:

$P(A \cap B) = P(A)P(B)$

Thus, P(A and B)=P(A)•P(B) is used when two events are independent.
