Finding the slope of a line.

Answer:

-(1/2)

Step-by-step explanation:

Slope is the Rise/Run

Going from left to right for (2, -6), (-4,-3):

Rise = (-3 - (-6)) = 3

Run = (-4, -2) = -6

Slope = Rise/Run = 3/-6 = -(1/2)

Answer:

Store number 1 has the best discount.

Step-by-step explanation:

Find how much of a discount you get from each store. For number 1 you find 30% of $150 by turning the percent to a decimal and multiplying, for number 2 you would subtract 150 - 30, and for number 3 you subtract 150 - 1/5. When all of this is done you get the greatest discount of $45 off from store number 1.

Step-by-step explanation:

Answer:

Population 15 years later  P(15)  =  100 + 50/π

Population 35 years later P(35)  =  200 + 50/π

Population any t ≥ 0    P(t) = 35 + 50 /π + 5*t + 10*cos(π*t/5)  

Step-by-step explanation:

P´(t)  =  5  + 10*sinπt/5       ⇒    dP/dt =  5  + 10*sinπt/5    

dP = ( 5  + 10*sinπt/5  ) *dt

P(t) = ∫  ( 5  + 10*sinπt/5 ) dt

P(t)  =  5*t  +  10 * ∫ sinπ*t/5* dt

P(t)  =  5*t  -  10*5/π *cos πt/5 + k

To determine k    t = 0   P(t) = 35

P(0) = 5*0  - 50/π (1) + k

35 = - 50/π  + k

k  =  35  + 50/π     and

P(t)  =  5*t  + 10*cos(π*t/5) + 35 + 50/π

b)P(t) = 35 + 50 /π + 5*t + 10*cos(π*t/5)    (1)

a) Population 15 years later

P(15)  =  35 + 50/π  + 5*15 - 10

P(15)  =  100 + 50/π

Again from equation  (1)

P(35)  =  35 + 50 /π + 5*35 + 10*cos(35*π/5)

P(35)  =  35 + 50/π  + 175 + 10*cos (7*π )

P(35)  =  210 + 50/π  - 10

P(35)  =  200 + 50/π

Answer:

3 terms

Step-by-step explanation:

Hi there!

Terms are constants or variables in an algebraic expression separated by plus and minus signs.

With this information, that means that 7q is a term, 6q is a term, and 2 is a term.

Without simplifying the expression, there are 3 terms.

Answer:

7875 square inches

Step-by-step explanation:

4ft^2 = 2ft * 2ft

4ft^2 = 3in * 3in

4ft^2 = 9in^2

For 3,500 square foot

3,500 square foot  = x

Divide bith expressions

4/3500 = 9/x

4x = 9 * 3500

4x = 31500

x = 31500/4

x = 7875 square inches

Hence the area of the house in inches is 7875 square inches

Answer:

£18,225

Step-by-step explanation:

2.5% of £16,200 = £405

10% of £16,200 = £1,620

5% of £16,200 = £810

5 years: 16,200 + 5 x 405 = £18,225

Answer:

1 pounds

Step-by-step explanation:

It basically means theres 1000 things that all weigh the same, so they add up to 0.1 pounds (0.1/1000= 0.00001 ) All you need to do is multiply by 10 so it would be 1 pound :)

Answer:

She has 2,660 combinations

Step-by-step explanation:

Here, we want to calculate the number of different combinations of 3 movies that can be rented

The condition is at least two horror movies

What this means is that she can select 2 or 3 horror movies

if two horror movies, then 1 foreign film

The combination is as follows;

20 C 2 * 8 C 1

= 190 * 8 = 1,520

If she is selecting 3 horror movies, then no foreign film will be selected

Number of ways this can be done is;

20 C 3 = 1,140

So the

number of different combinations would be;

1,140 + 1,520 = 2.660

Answer:

1. 1900 children.

2. 600 adults.

Step-by-step explanation:

Let c represent the number children.

Let a represent the number of adult.

From the question given above, we were told that 2500 people entered the fair. This can be obtained as follow:

2500 = c + a ..... (1)

From the question given above, we were told that:

Cost per child = $ 2

Cost per adult = $ 4

Total amount collected = $ 6200

Thus, we can write the above as:

6200 = 2c + 4a .....(2)

Summary:

2500 = c + a ..... (1)

6200 = 2c + 4a .....(2)

1. Determination of the number of children that attended the fair.

From equation 1

2500 = c + a

Make a the subject by rearranging

a = 2500 – c ....... (3)

Substitute the value of 'a' in equation 3 into equation 2

6200 = 2c + 4a

a = 2500 – c

6200 = 2c + 4(2500 – c)

Clear bracket

6200 = 2c + 10000 – 4c

Collect like terms

6200 – 10000 = 2c – 4c

–3800 = –2c

Divide both side by –2

c = –3800 / –2

c = 1900

Thus, 1900 children attended the fair

2. Determination of the number of adults that attended the fair.

Substitute the value of c into equation 3.

a = 2500 – c

c = 1900

a = 2500 – 1900

a = 600

Thus, 600 adults attended the fair.

Answer:f

( x ) = x ,  g ( x ) = x 3 − 1 f ( x ) = x 4 + x 3 − 11 x 2 − 5 x + 30 ,  g ( x ) = 2 x − 2 f ( x ) = x 2 ,  g ( x ) = 7 x − 1

in short ways the answer is  7 x − 1

Hence , the sum is [tex]11x^2-8x-14[/tex].

In mathematics, a polynomial is an expression consisting of indeterminates (also called variables) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

Given , we need to add [tex]2x^2-8x-6[/tex] and [tex]9x^2-8[/tex].

So, we can write it as :

[tex]2x^2 -8x-6+9x^2-8[/tex]

Writing like terms together:

[tex]= 2x^2+9x^2-8x-6-8[/tex]

[tex]=11x^2-8x-14[/tex]

Hence , the answer is [tex]11x^2-8x-14[/tex].

Answer:

a. decrease

b. recklessly

c. increase

Step-by-step explanation:

Suppose the large number of auto accidents in a small town results in new legislation that requires all citizens of the town to install new anti-lock brakes on their cars. These new brakes cut the time it takes a car to stop by 50%, allowing drivers to avoid collisions with other cars and pedestrians more easily. The new brakes decrease the probability that a vehicle will collide with another vehicle but also give drivers an incentive to drive more recklessly which could potentially increase the number of car accidents.

Because the new brakes cut the time it takes a car to stop by 50%, allowing drivers to avoid collision easily, drivers may become confident and drive recklessly which could potentially increase the number of car accidents
