answer asap pls ---------------

Answers

Answer:

option C.

Step-by-step explanation:

roots of a function are the values of x for which the corresponding value of f(x) is 0.

since f(x) is being plot on the y axis it's value being zero signifies the intersection of the curve with the x axis.

so the roots of g(x) are :-

2, and 10

for roots of f(x) :-

f(x) = 0

x² - 9 = 0

(x+ 3)(x - 3) = 0

either x = 3 or x = -3

so the roots of f(x) are

3, and -3

Comparing their roots one can very well see both the functions share no roots in common.

Option c is the answer hope it helps

eric has a summer lawn mowing buisness. based on experience eric knows that p= -3x^2 + 150x -1200 models his profit, p, in dollars, where x is the amount he charges per lawn. how much does he need to charge if he wants to break even? show your work

Answers

Answer:

Eric can either charge $10 or $40 in order to break even.

Step-by-step explanation:

Eric has a summer lawn mowing business and the equation:

[tex]p=-3x^2+150x-1200[/tex]

Models his total profit p by charging x dollars per lawn.

We want to determine what price Eric needs to charge in order to break even.

The price Eric charges to break even means that his total profit will be zero. Hence, we can let p = 0 and solve for x. Thu:

[tex]0=-3x^2+150x-1200[/tex]

We can divide both sides by -3:

[tex]0=x^2-50x+400[/tex]

Factor:

[tex]0=(x-10)(x-40)[/tex]

Zero Product Property:

[tex]x-10=0\text{ or } x-40=0[/tex]

Solve for each case. Hence:

[tex]x=10\text{ or } x=40[/tex]

Therefore, Eric can either charge $10 or $40 in order to break even.

James is 8 years old. Last year, his father was 4 times as old as he was. In how many years' time will their combined age be 51?

Answers

Last year He was 7 years old.

His father is 4 times the age 7 x 4 = 28

Last year his dad was 28, so this year he is 29.

Combined age this year = 29 + 8 = 37

51 - 37 = 14 years

14/ 2 people = 7 years

8 + 7 = 15

29 + 7 = 36

15 + 36 = 51

It will take 7 years.

H1 : The mean difference in strikes between pre and post strike is not equal to 0

Step-by-step explanation:

The scenario described abibe meets the condition for a paired (dependent) sample t test as the same subject is involved in both the pre and post strike data. Therefore measurement from the strike(pre) must be paired with measurement from the strike(post) data.

For a paired test involving a single subject ; The mean difference in the two sample is 0 ; that is both are the same while the alternative negates the null by claiming that the mean difference is not equal to zero.

Answers

Answer:

$1,281.00

Step-by-step explanation:

We start by calculating the value $50 added each month after the first month

= $50 × 11

= $550

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5.5%/100 = 0.055 per year.

P = Principal = 500 + 550

= $1050

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5.5%/100 = 0.055 per year.

Solving our equation:

A = 1050(1 + (0.055 × 4)) = 1281

A = $1,281.00

Therefore, there would be $1,281.00 after 4 years.

Juan, Pedro y Luis construyen un muro de 60 metros de largo. Juan construye el triple de Pedro y Luis el doble de Juan. ¿Cuántos metros construyó cada uno?

Answers

Answer:

Pedro make 6 m of wall, Juan make 18 m of the wall and Luis make 36 m of the wall.

Step-by-step explanation:

Juan, Pedro and Luis build a 60 meter long wall. Juan builds triple the size of Pedro and Luis double the size of Juan. How many meters did each one build?

Total length of the wall is 60 m.

Let Pedro make p length of the wall.

Juan make = 3 p

Luis make = 6 p

So,

According to the question

60 = p + 3 p + 6 p

60 = 10 p

p = 6

So, Pedro make 6 m of wall, Juan make 18 m of the wall and Luis make 36 m of the wall.

The measure of two supplementary angles are A=(4a+7)° and B=(a-2)° find the measure of the two angles

Answers

Answer:

147˚, 33˚

Step-by-step explanation:

supplementary angles means those angles add up to 180˚

so A+B = 180

substitute A and B with the values given.

(4a+7) + (a-2) = 180

combine like terms

5a + 5 = 180

5a = 175

a = 35

Now that we have a, substitute in the actual value of a into the expressions for each angle.

for <A: 4(35) + 7 = 147˚

for <B: 35 - 2 = 33˚

Answer:

<A =147

<B =  33

Step-by-step explanation:

Supplementary angles add to 180

4a+7 + a-2 = 180

5a+5 = 180

5a+5-5 = 180-5

5a = 175

Divide by 5

5a/5 = 175/5

a = 35

<A = 4a+7 = 4*35 +7 = 140+7=147

<B = a-2 = 35-2 = 33

Answers

Answer:

40 pupils speak French and English

5 pupils speak only English

Step-by-step explanation:

**The grammar has some errors, but I hope I understood it correctly to answer your question correctly!**

Here's what we know about the question:

- 1/10 of the 50 pupils speak only FRENCH

- 4/5 of the 50 pupils speak FRENCH and ENGLISH

- rest of the pupils speak only ENGLISH

Here's what we're trying to find:

- # of pupils that speaks FRENCH and ENGLISH

- # of pupils that speak only ENGLISH

Let's start of with find how many pupils speak French:

1/10 of the 50 pupils speak French. To find the # of pupils, divide 50 by 10:

50/10 = 5

5 pupils speak only French

Now let's find out how many pupils speak French and English:

4/5 of the 50 pupils speak French and English. We are going to divide 50 by 5 and then multiply the result by 4:

50/5 = 10

10 * 4 = 40

40 pupils speak French and English

Finally, let's find the number of pupils that speak only English:

The question only says that the rest of the 50 pupils speak only English.

We are going to add the other pupils who don't speak only English, then subtract that value from 50:

40 + 5 = 45

50 - 45 = 5

5 pupils speak only English

Answer:

d. The APR helps compare loans with the same payback period, but with different monthly rates and different fees.

Step-by-step explanation:

A loan can be defined as an amount of money that is being borrowed from a lender and it is expected to be paid back at an agreed date with interest.

Generally, the financial institution such as a bank lending out the sum of money usually requires that borrower provides a collateral which would be taken over in the event that the borrower defaults (fails) in the repayment of the loan.

An annual percentage rate (APR) is an amount of money paid as interest by borrowers or earned on loans by lenders such as banks, expressed as a percentage of the amount borrowed or invested over a 12-month period i.e on an annual basis.

He wanted to expand westward to create more farmland. Jefferson also wanted to obtain the Port of New Orleans at the mouth of the Mississippi River so farmers could easily transport their goods. He facilitated the purchase of New Orleans and the rest of the French territory from France in 1803 for $15 million. This new land was called the Louisiana Territory and stretched partway across the continent. It was the first step in expanding the United States. The purchase of the Louisiana Territory led to a pattern of westward expansion through payment, negotiations, and conflict.Read the passage from the website: www.expandingcountries.edu/unitedstates/louisianapurchaseThe Louisiana Purchase doubled the size of the United States and vastly increased its resources and riches. The roles of the president and the Constitution were also defined, as it was determined that the president could purchase the land without consulting Congress. Despite the advantages of expanding westward, one prominent disadvantage was the growing tension between slave states and free states regarding whether new states would permit slavery.
