What are the x-intercepts of the function f(x)=(x + 1)(x + 4)?
Brilliant_brown [7]

Answer:

B

Step-by-step explanation:

To find the x- intercepts let f(x) = 0 , that is

(x + 1)(x + 4) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x + 1 = 0 ⇒ x = - 1

The x- intercepts are (- 4, 0 ) and (- 1, 0 )

Elmer purchased a used vehicle that depreciates under a straight line method. The initial value of the car is $9600 and the salv
Igoryamba

Answer:

The depreciation each year is option B. $1500.00

Step-by-step explanation:

Initial value of car = $9600

Salvage value = $600

Salvage value is the final value of product after all the depreciation have been applied on the product.

So, total depreciation on the car = \$9600 -  \$600 \Rightarrow \$9000

Also, it is given that the depreciation occurs at a straight line method i.e. same depreciation occurs every year.

Depreciation in 6 years = $9000

Depreciation in 1 year =

\dfrac{\$9000}{6} \Rightarrow \$1500

Hence, option B. $1500 is the correct answer for the depreciation every year.

A card is selected randomly from a jar that contains 15 cards, numbered from 25 to 39. What is the probability that the card sel
VikaD [51]

Answer:

The probability that the card selected bears a number less than 34 is 0.3333.

Step-by-step explanation:

Let random variable <em>X</em> be defined as the number on the selected card.

There are <em>N</em> = 15 total cards.

The number on the cards are as follows:

S = {25, 26, 27,..., 38, 39}

The probability of an event, <em>E</em> is the ratio of the number of favorable outcomes to the total number of outcomes.

P(E)=\frac{n(E)}{N}

In this case we need to compute the probability that the card selected bears a number less than 34.

The favorable outcomes are:

<em>s</em> = {25, 36, 37, 38, 39}

<em>n</em> (X < 34) = 5

Compute the probability that the card selected bears a number less than 34 as follows:

P(X

                  =\frac{5}{15}\\\\=\frac{1}{3}\\\\=0.3333

Thus, the probability that the card selected bears a number less than 34 is 0.3333.
