George wants to rent a car for a road trip with his friends. He checked the rentals with two companies. Company A charges a non-

refundable fee of $50 and then also $150 for each day. Company B charges using the function 50(2+1). Compare the two functions. Which function has a great rate of change?

Answer:

Company A has a greater daily rate

Step-by-step explanation:

Given

Company A

$Base\ Charges=\$50$

$Daily\ Rate = \$150$

Company B

$f(x) = 50(2x +1)$

Required

Determine the company with greater rate

Simplify the expression of company B

$f(x) = 50(2x +1)$

$f(x) = 50 * 2x + 50 * 1$

$f(x) = 100x + 50$

In a linear function:

$f(x) = mx + b$

m represents the rates.

This implies that the rate of company B is:

$Rate =100$

and the rate of company A is

$Daily\ Rate = \$150$

By comparison:

Company A has a greater daily rate

Whisper the numbers in standard form and unit form 42

prisoha [69]

Answer:

In standard form 42= $4.2\times 10^1$

In unit form, 42 as 4 tens 2 ones

Step-by-step explanation:

<u>Standard form</u>: It is the way of writing down the numbers easily in a very large or small numbers.

Rules for writing a number in standard form is that first you write down a number between 1 and 10, then multiply the number with 10(to the power of a number).

Now, to write

42 in standard form: $4.2\times 10^1$ .

Unit form: it is a form that express the number by giving the number of place value within the number.

Unit form of 42:

42 is written as 4 tens , 2 ones.

A triangular lot has sides of 215m, 185m, and 125m. Find the measures of the angles at its corners

Vlada [557]

Answer:

The measures of the angles at its corners are $59.1\°,35.4\°,85.5\°$

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the measure of angle A

Applying the law of cosines

$185^{2}= 215^{2}+125^{2}-2(215)(125)cos(A)$

$2(215)(125)cos(A)= 215^{2}+125^{2}-185^{2}$

$cos(A)= [215^{2}+125^{2}-185^{2}]/(2(215)(125))$ $cos(A)=0.513953$

$A=arccos(0.513953)=59.1\°$

step 2

Find the measure of angle B

Applying the law of cosines

$125^{2}= 215^{2}+185^{2}-2(215)(185)cos(B)$

$2(215)(185)cos(B)= 215^{2}+185^{2}-125^{2}$

$cos(B)= [215^{2}+185^{2}-125^{2}]/(2(215)(185))$ $cos(B)=0.81489$

$B=arccos(0.81489)=35.4\°$

step 3

Find the measure of angle C

Applying the law of cosines

$215^{2}= 125^{2}+185^{2}-2(125)(185)cos(C)$

$2(125)(185)cos(C)= 125^{2}+185^{2}-215^{2}$

$cos(C)= [125^{2}+185^{2}-215^{2}]/(2(125)(185))$ $cos(C)=0.0784$

$C=arccos(0.0784)=85.5\°$
