42) According to the 2000 Census the population of Canton was 7,720. Holly Spring's population was 3,200. Canton's population increases at a rate of 80 people a year and Holly Spring's population increases by 120 people a year. Which equation may be used to determine the number of years before the populations are equal?

Answers

Answer 1
Let's construct an equation for Canton's population increase as 7220+80n and Holly Spring's population increase with 3200+120n, where n is the number of years. We have to set these equations to each other in order to find when the population of these two places are equal. 3200+120n=7220+80n and n=100.5. After 100 and half years

(5x^2+38x+18) divided (x+7) what is the quotient and the remainder

Answers

Final answer:

To determine the quotient and remainder for (5x^2+38x+18) divided by (x+7), polynomial long division must be used, involving dividing terms, multiplying and subtracting until the remainder is obtained.

Explanation:

To find the quotient and remainder of the division of polynomials (5x2+38x+18) by (x+7), we can use polynomial long division.

Divide the first term of the dividend, 5x2, by the first term of the divisor, x, to get the first term of the quotient, which is 5x. Multiply the entire divisor (x+7) by 5x and subtract from the dividend. Bring down the next term from the dividend and repeat the process until there are no more terms to bring down. The last line after the subtraction will be the remainder.

By doing this, you will obtain the quotient and the specific remainder for this division.

What is the measure of ∠F, to the nearest degree?
44°
57°
71°
78°

Answers

it is A-44 hope this helps

Answer:

Option A. 44°

Step-by-step explanation:

In a given triangle FGH sides have been given as FG = 7 yards, FH = 6 yards, and GH = 5 yards.

We have to calculate the approximate value of ∠F.

We apply the cosine rule in the given triangle.

5² = 7² + 6² - 2×7×6×cosF

25 = 49 + 36 - 84× cosF

25 = 85 - 84 cosF

84cosF = 85 - 25 = 60

[tex]cosF=\frac{60}{84}=0.71428[/tex]

[tex]F=cos^{-1}( 0.71428) = 44.4[/tex]

F = 44°

Therefore option A. 44° is the correct answer.

Find the quotient of 3/5 and 9/10 . Express your answer in simplest form.

Answers

Hello there, and thank you for asking your question here on brainly.

Short answer: 2/3

Why?

When dividing two fractions, you don't divide, you find the reciprocal of the second fraction (9/10) and multiply. So, it's 3*10/9*5. Simplify. {3 * 10 => 30} ~ {9 * 5 => 45} Now we have 30/45. This can be simplified. Simplified, 30/45 reduces down to 2/3.

Hope this helped you! ♥

The quotient of 3/5 and 9/10 is the value obtained by dividing both values, Hence, the quotient of the division is 2/3

The numerator = 3/5

The denominator = 9/10

The division operation can be expressed thus :

3/5 ÷ 9/10

Take the reciprocal of the denominator and change the sign to multiplication ;

Reciprocal of 9/10 = 10/9

Hence, we have ;

3/5 × 10/9 = 30/45

In simplest form ; 30/45 = 10/15 = 2/3

Therefore, the quotient is 2/3

What is the middle term of the product of (x - 4)(x - 3)?

Answers

Answer:

The middle term of the product of (x - 4)(x - 3) is -7

Step-by-step explanation:

Consider the given expression (x - 4)(x - 3)

We have to find the middle term of the product of (x - 4)(x - 3).

First multiply the given terms, we get,

[tex](x - 4)(x - 3)=x(x-3)-4(x-3)[/tex]

Simplify, we get,

[tex]x(x-3)-4(x-3)=x^2-3x-4x+12[/tex]

Simplify further, we get,

[tex]x^2-3x-4x+12=x^2-7x+12[/tex]

Thus, the middle term of the product of (x - 4)(x - 3) is -7

a) The signs of the first derivative (g') tell you the graph increases as you go left from x=4 and as you go right from x=-2. Since g(4) < g(-2), one absolute extreme is (4, g(4)) = (4, 1).

The sign of the first derivative changes at x=0, at which point the slope is undefined (the curve is vertical). The curve approaches +∞ at x=0 both from the left and from the right, so the other absolute extreme is (0, +∞).

b) The second derivative (g'') changes sign at x=2, so there is a point of inflection there.

c) There is a vertical asymptote at x=0 and a flat spot at x=2. The curve goes through the points (-2, 5) and (4, 1), is increasing to the left of x=0 and non-increasing to the right of x=0. The curve is concave upward on [-2, 0) and (0, 2) and concave downward on (2, 4]. A possible graph is shown, along with the first and second derivatives.

We have 31,100 is rounded to the nearest power of 10 and [N] represents a power of 10.

We can write -

10ⁿ = 31100

10ⁿ = 311 x 10²

10ⁿ ⁻ ² = 311

log(10ⁿ ⁻ ²) = log(311)

(n - 2) log 10 = log (311)

When rounding 31,100 to the nearest power of 10, we get the value of n is 4.

To find the value of n when 31,100 is rounded to the nearest power of 10, we first need to determine which powers of 10 are closest to 31,100. The nearest powers of 10 to 31,100 are 104 (10,000) and 105 (100,000). Since 31,100 is closer to 104 than to 105, we round it down to 104.

Therefore, when 31,100 is rounded to the nearest power of 10, the value of n is 4.

The process involves converting the number into scientific notation and then adjusting the exponent, which represents the number of places the decimal point moves. In our case, to convert 31,100 to a number between 1 and 10, we would express it as 3.11 × 104, confirming that the value of n is 4.

Jonathan opened an auto repair shop. In the first month, 11 cars were serviced at his shop. The number of cars serviced at Jonathan's shop increased at 9 cars per month.

How many total cars were serviced at Jonathan's shop at the end of the 7th month?

329 cars
65 cars
266 cars
201 cars

Answers

The number of cars in first month = 11
Number of cars in second month = 11 + 9 =20
Number of cars in third month = 20 + 9 = 29

If we observe, the number of cars form an Arithmetic sequence with first term as 11 and common difference 7. We are to find the total cars received till the end of 7th term in the shop i.e. we are to find the sum of first 7 terms of the sequence.

So, using the formula of sum Arithmetic series we can write:

Cars  received in 7th months = [tex] \frac{7}{2}(2(11)+(7-1)(9)) = 266 [/tex] cars

Thus, 266 cars were received at the end of 7th month at Jonathan's auto repair shop.

Find the inverse function f^-1(x) for the given function f(x). f(x) =3x-8

Answers

[tex]f(x)=3x-8\\\\y=3x-8\ \ \ \ |+8\\\\3x=y+8\ \ \ \ |:3\\\\x=\dfrac{y+8}{3}[/tex]

Answer: [tex]y=\dfrac{x+8}{3}=\dfrac{1}{3}x+\dfrac{8}{3}[/tex]

Final answer:

To find the inverse of the function f(x) = 3x - 8, you swap x and y and solve for y, resulting in the inverse function f^-1(x) = (x + 8) / 3.

Explanation:

To find the inverse function f-1(x) for the given linear function f(x) = 3x - 8, we will follow these steps:

Replace f(x) with y: y = 3x - 8.

Swap x and y to make it x = 3y - 8.

Solve for y to get the inverse function.

Starting with x = 3y - 8, we add 8 to both sides to obtain x + 8 = 3y. Then, we divide both sides by 3 to isolate y, resulting in y = (x + 8) / 3. Therefore, the inverse function is f-1(x) = (x + 8) / 3.

Bill buys a red marble and a blue marble. If the total weight of 3 such red marbles and 2 such blue marbles is 84g, and the total weight of 12 such red marbles and 5 such blue marbles is 282g, what is weight of the red marble and the blue marble respectively?

Answers

Final answer:

The weight of the red marble is 16 grams, and the weight of the blue marble is 18 grams, based on the solution of the system of linear equations derived from the given total weights of the marbles.

Explanation:

To solve the problem of determining the weight of each marble, we can set up a system of linear equations based on the given information:

Let r be the weight of a red marble in grams.

Let b be the weight of a blue marble in grams.

The total weight of 3 red marbles and 2 blue marbles is 84g.

The total weight of 12 red marbles and 5 blue marbles is 282g.

Based on these statements, we can write two equations:

3r + 2b = 84 (1)

12r + 5b = 282 (2)

We can solve this system of equations by multiplying equation (1) by 4 to eliminate variable b.

(4)(3r + 2b) = (4)(84)

12r + 8b = 336 (3)

Subtract equation (2) from equation (3) to solve for r:

(12r + 8b) - (12r + 5b) = 336 - 282

3b = 54

b = 18 (weight of blue marble)

Substitute value of b in equation (1) to solve for r:

3r + 2(18) = 84

3r + 36 = 84

3r = 48

r = 16 (weight of red marble)

Therefore, the weight of the red marble is 16 grams and the weight of the blue marble is 18 grams.

Square the number

V = 3.14 * 9 * 7 

Multiply

Next you find the volume of the sphere

To find the volume of a sphere you use the equation

[tex]V = \frac{4}{3} \pi r^{3} [/tex]

V is volume
r is radius

Put in the values you know and 3.14 for pi

[tex]V = \frac{4}{3} * 3.14 * 3^{3} [/tex]

Cube the number

[tex]V = \frac{4}{3} * 3.14 * 27[/tex]

Multiply

V = 113.04
