Which is an odd monomial function? A.y=2x^3 B.1/x C.5x^-9 D.3
Anna71 [15]
First let's review two concepts:
 Monomy: Algebraic expression that consists of a single term or in which the terms that form it are related by the product operation.
 Odd function: A function is odd if, for each x in the domain of f, f (- x) = - f (x).
 The function y = 2x ^ 3 complies with both definitions.
 Answer:
 an odd monomial function is:
 
A.y = 2x ^ 3

A survey found that 8 out of 10 parents approved of the new principal’s performance. If 4 parents name are chosen with replaceme
Natasha2012 [34]

Answer:

The probability is 0.044

Step-by-step explanation:

Step-by-step explanation:

Let p be the probability that the new principal’s performance is approved.

This is obtainable from the survey and it is 8/10 = 0.8

Let q be the probability that the new principal’s performance is disproved.

That will be;

1 - q = 1- 0.8 = 0.2

To calculate the probability that 14 parents names are chosen at random and they all

approve of the principal’s performance, we use the Bernoulli approximation of the binomial theorem.

That will be;

14C14 * p^14 * q^0

= 1 * 0.8^14 * 0.2^0

= 0.043980465111 which is approximately 0.044

A bank security camera is mounted on a wall. The camera is set at an angle of depression of 19 degrees so that it is focused on
777dan777 [17]

Answer:

8.95feet

Step-by-step explanation:

The set up is a right angled triangle where;

The camera's horizontal distance from the focus point = 26feet = Adjacent;

The height of the camera above the floor = Opposite = x

Angle of elevation = 19°

According to TOA in trig identity;

Tan theta = opp/adj

Tan 19 = x/26

x = 26tan 19

x = 26(0.3443)

X = 8.95feet

Hence the camera is placed at a height of 8.95feet above the floor
