A New York taxi service charges a $3.25 boarding rate in addition to its meter which is $2 for every mile. How much does it cost

IgorC [24]

Answer:

Hey there!

This can be modelled by an equation, y=2x+3.25

For one mile: y=2(1)+3.25, or y=5.25

For twenty miles: y=2(20)+3.25, or y=43.25

Hope this helps :)

Factor completely: 2x4 − 32.

vazorg [7]

Answer:

Option b) is correct.

The completed factor of given expression is $2(x-2)(x+2)(x^2+4)$

Step-by-step explanation:

Given expression is $2x^4-32$

To find the completed factor for the given expression:

$2x^4-32$ :

Taking the common number "2" outside to the above expression we get

$2x^4-32=2(x^4-16)$

Now rewritting the above expression as below

$=2(x^4-2^4)$ (since 16 can be written as the number 2 to the power of 4)

$=2((x^2)^2-(2^2)^2)$

The above expression is of the form $a^2-b^2=(a+b)(a-b)$

Here $a=x^2$ and $b=2^2$

Therefore it becomes

$=2(x^2+2^2)(x^2-2^2)$

$=2(x^2+4)(x^2-2^2)$

The above expression is of the form $a^2-b^2=(a+b)(a-b)$

Here $a=x$ and $b=2$

Therefore it becomes

$=2(x^2+4)(x+2)(x-2)$

$=2(x+2)(x-2)(x^2+4)$

Therefore $=2(x+2)(x-2)(x^2+4)$

$2x^4-32=2(x-2)(x+2)(x^2+4)$

Option b) is correct.

The completed factor of given expression is $2(x-2)(x+2)(x^2+4)$

Help me to solve this question

Anastasy [175]

Answer:

$\frac{6}{25}$

Step-by-step explanation:

$P(A) = \frac{number \: of \: times \: A \: occurs}{total \: number \: of \: spins}$

$P(A) = \frac{12}{12 + 16 + 13 + 9} = \frac{12}{50} = \frac{6}{25}$
