The diameter of a circle is 4 kilometers. What is the radius?
d=4 km

Answer:

A: 10x^2 +53x +63   B: degree 2; quadratic trinomial  C: the result of the multiplication of polynomials is a polynomial

Step-by-step explanation:

Part A:

The area is the product of length and width. The distributive property is useful for simplifying the expression.

 A = LW

 A = (2x +7)(5x +9) = 2x(5x +9) +7(5x +9)

 A = (10x^2 +18x) +(35x +63)

 A = 10x^2 +53x +63 . . . . area expression

Part B:

The highest power of x is 2. There are 3 terms. A degree-2 polynomial is called a "quadratic." A 3-term polynomial is called a "trinomial."

degree 2

quadratic trinomial

Part C:

In part A we multiplied two polynomials and came up with a result that is a polynomial. This suggests polynomials are closed with respect to multiplication.

I hope this helps!!

Answer:

The height is [tex]\sqrt{106}[/tex] feet

Step-by-step explanation:

First, lets assign and categorize the information given to us:

Area = 106 [tex]ft^{2}[/tex]

b = 2h (Base is twice the height)

Next, lets look at the formula for the area of a triangle:

Area = [tex]\frac{1}{2} bh[/tex]

Then, lets substitute the given information and solve:

106 = [tex]\frac{1}{2}[/tex] * 2h * h
106 = [tex]h^{2}[/tex]
[tex]\sqrt{106}[/tex] feet = h

Answer: Hence the cost of operating theater if there are 100 people at a show is 20,000Rs.

Step-by-step explanation:

Theater is a place where the movies are shown in big screens and Speakers are used for the clear audio of the movie.

In a theater there will be 3 to 4 shows for a movie or different movie.

Theater can consist of 250 - 300 seats and can cost up to 250rs for a seat.

Consider a ticket cost of 200rs. For 100 people in a show ,

                              Cost = 200 × 100

                               Cost = 20,000.

Hence the cost of operating theater if there are 100 people at a show is 20,000Rs.

Let's solve

PutC=65

Answer:

The value of p = $15

Step-by-step explanation:

Given equation is C = 2p + 35

and the C is $65

Putting the value of c in equation

=> 65 = 2p + 35

=> 65-35 = 2p

=> 30 = 2p

=> 30/2 = p

=> p = 15$

Step-by-step explanation:

The tank fills up at a daily rate of

(6 gal/hr) (24 hr/day) = 144 gal/day

so the net rate is

144 gal/day - 69 gal/day = 75 gal/day

and after 24 hours, the tank would contain 75 gal of water.

75 gallons of water would be in the tank after 24 hours.

Tank A fills at a rate of 6 gallons/hr

We know that, 1 day = 24 hours

So, Tank A fills in a day = (6 × 24) gallons

Given that, The tank discharge water at a rate 69 gallons per day.

Total water in the tank A in 24 hours = 144 gallons

Tank A discharge water in 24 hours = 69 gallons

∴ Water left in the tank A after 24 hours = (144-69) gallons

                                                                  = 75 gallons

Answer:

2nd option

Step-by-step explanation:

7x - y =  7 ( multiply through by - 1 )

- 7x + y =- 7 ( add 7x to both sides )

y = 7x - 7 → (1)

7x² - y = 7 → (2)

substitute y = 7x - 7 into (2)

7x² - (7x - 7) = 7 ← distribute parenthesis on left side

7x² - 7x + 7 = 7  ( subtract 7 from both sides )

7x² - 7x = 0 ← in standard form

7x(x - 1) = 0 ← in factored form

equate each factor to zero and solve for x

7x = 0 ⇒ x = 0

x - 1 = 0 ⇒ x = 1

substitute these values into (1) for corresponding values of y

x = 0 : y = 7(0) - 7 = 0 - 7 = - 7 ⇒ (0, - 7 )

x = 1 : y = 7(1) - 7 = 7 - 7 = 0 ⇒ (1, 0 )

Answer:

4x³ + 12x²

Step-by-step explanation:

I assume the denominators are x² and 4x although that is not what you wrote.

x² = x² (already factored)

4x² + 12x = 4x(x + 3)

LCD = 4 × x² × (x + 3)

LCD = 4x³ + 12x²

A) 22cm

( divide the length value by 100)

=》 Solution;

solving,

x+2x+6x+18=180

or, 9x + 18 = 180

or, x + 18 = 180/9

or, x + 18 = 20

or, x = 20 - 18

or, x = 2

therefore, value of x is 2

now,

i) x = 1 X x = 1 X 2 = 2

ii) 2x = 2 X x = 2 X 2 = 4

iii) 6x = 6 X x = 6 x 2 = 12

Answer:

20 miles

Step-by-step explanation:

10 x 2 = 20

10 miles is half the drive so you'd just multiply it by 2 and that would be the full amount of miles home.

Answer:

The total length of Nicol’s drive would be 20 miles.

If The first half of her trip takes 10 miles then the second half would have an equal number of miles. 10x2=20

You would use 10 two times because 1/2+1/2=1.

Therefore the total amount of miles Nicole will travel will be 20.

Answer:

For no values of x.

Step-by-step explanation:

A function is increasing when its graph is sloping upwards.

Conversely, a function is decreasing when its graph is sloping downwards.

From the given graph, we can see that it is sloping downwards at all x values. In other words, it is always decreasing and never increases.

Therefore, for no values of x is the graph increasing.

Step-by-step explanation:

The hypothesis illustrates that C. Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim.

Using a graphing calculator and calculated the t-interval of the jellybean sample using a 99% confidence level:

tInterval 9.68,1.23,125,0.99

It resulted in 9.68 ± 0.287805.

Therefore, we're 99% confident that the weight number of jellybeans would lie between 9.3922 oz and 9.9678 oz.

Therefore, the researcher failed to reject the null hypothesis.

Complete question:

A weight of 9.45 oz lies within this range, therefore, it is possible that the candy company's claim is true.

A candy company claims that their bags of jellybeans have a mean weight of 9.45 oz. 125 randomly chosen bags of jellybeans were sampled, and it was discovered that their mean weight was 9.68 oz, with a standard deviation of 1.23 oz. Test this hypothesis using a 99% confidence level.

A- Reject the null hypothesis. There is not enough evidence to oppose the company's claim.

B- Reject the null hypothesis. There is enough evidence to oppose the company's claim.

C- Fail to reject the null hypothesis. There is not enough evidence to oppose the company's claim.
