We are given function : f(x)=7x^3-3x^2-6.

We need to describe the end behavior of the given function.

In order to describe end behavior of a function we need to find the degee and leading coefficient of the given function.

Degree of the given function is the maximum power of the exponent.

We have x^3, there.

Therefore, degree of the given function is : 3 an odd degree and

Leading coefficient is : 7 a positive number.

<em>According to end behavior rule, when degree is an odd degree and leading coefficient is a positive number the f(x) would be of same sign as x.</em>

Therefore end behavior would be

Answer: 13%

Step-by-step explanation:

We know that the formula to find the simple interest :

$I=Prt$ , where P is the principal amount , r is rate (in decimal )and t is the time period (in years).

Given : Albert borrowed $19,100 for 4 years. The simple interest is $9932.00. Find the rate.

i.e. P = $19,100 and t= 4 years and I = $9932.00

Now, Substitute all the values in the formula , we get

$9932=(19100)r(4)\\\\\Rightarrow\ r=\dfrac{9932}{19100\times4}\\\\\Rightarrow\ r=0.13\ \ \ \text{[On simplifying]}$

In percent, $r=0.13\times100\%=13\%$

Hence, the rate of interest = 13%

5/6+2/9= in simplest form I NEED this plz help

tensa zangetsu [6.8K]

Answer: 1 1/18

Step-by-step explanation: 5/6 + 2/9 I know this might seem like common, but <em>the </em><em>Numerator is the top number of a fraction</em><em> and the </em><em>Denominator is the bottom a fraction.</em> When the numerator and the denominator are the same such as 5/5 the fraction equals one (I know its real fancy). When you're multiplying a fraction that equals on by another fraction its really just multiplying by a fancy looking 1 that's disguised as a fraction such as 5/5. If you simplify it it goes to the fraction it was as long it was simplified to the max (5/5 x 1/2 = 5/10= 1/2)

First, you need to find a like denominator, which is 18

Then, you got to multiply each fraction to make them have common denominators ...multiply 5/6 by 3/3 ( 3/3 is just a fancy way of saying one) 5/6 x 3/3 = 15/18....multiply 2/9 by 2/2 (which is just another fancy way of saying one ) 2/9 x 2/2=4/18
Next you add them but only the numerator 15/18 + 4/18 = 19/18
Finally, you change the the fraction into a mixed number 1 and 1/18

Question is Incomplete; Complete question is given below;

Mr. Lin hires a moving company to help transport furniture to his new home. The bill from the moving company is $400. Mr. Lin includes a 15% tip with his payment.

What is Mr. Lin’s total payment, including tip?

Answer:

Mr. Lin made a Total payment of $460 including the Tip.

Step-by-step explanation:

Given:

Total bill = $400

Percentile amount paid in tip = 15%

We need to find the total payment, including tip.

Solution:

First we will find the amount paid in Tip.

amount paid in Tip can be calculated by Percentile amount paid in tip multiplied by Total bill and then divided 100.

amount paid in Tip = $\frac{15}{100}\times 400 = \$60$

Now we know that;

Total payment made by Mr.Lin is equal to sum of Total bill and amount paid in Tip.

framing in equation form we get;

Total payment made by Mr.Lin = $\$400+\$60 =\$460$

Hence Mr. Lin made a Total payment of $460 including the Tip.
