The standard form of an equation of a circle with center at
(h, k)
and radius r is _____.

(y − h)2 + (x − k)2 = r2

(x − h)2 − (y − k)2 = r2


(y + h)2 − (x + k)2 = r2

(x − h)2 + (y − k)2 = r2

(x + h)2 − (y + k)2 = r2

Answer:

-5x^6 - 2x^5 + 4x^2 + 3x + 3

Step-by-step explanation:

Combine like terms from each of the polynomials.

(8x^2 + 5x + 3) + (-5x^6 - 2x^5 - 4x^2 - 2x)

(8x^2 - 4x^2) + (5x - 2x) + (3) + (-5x^6) + (-2x^5)

(4x^2) + (3x) + (3) + (-5x^6) + (-2x^5)

Then, order them by degree.

-5x^6 -2x^5 + 4x^2 + 3x + 3

One axis is used for kilograms, the other for pounds. When the x-axis is kilograms, the line includes points (1, 2.2), (2, 4.4), and (3, 6.6). The graph is a straight line that passes through the origin. The line is straight because unit conversions are proportional.

Answer:

57.5

Step-by-step explanation:

Recognize our numbers

3,5,34.50

Three uniform shirts sell for 34.50

34.50/3

=11.5

How much will five cost?

5x11.5

=57.5

Hope this helps!

Answer:

55.25

Step-by-step explanation:

1. First we need to work out the price of ONE shirt. To do that we divide the total price of 3 shirts by 3.

34.50 / 3 = 11.05

2. Now we know that the price of one shirt is $11.05p we can multiply that by 5 to get the price of 5 shirts.

11.05 * 5 = 55.25

= $55.25p

Answer:

B. 15 units

Answer:

[tex]P(x=3) = 0.1318[/tex]

Step-by-step explanation:

The question illustrates a binomial distribution and the given parameters are:

Given

[tex]n = 6[/tex] -- sample size

[tex]p = 0.75[/tex] --- probability of success

[tex]r = 3[/tex] --- half of the participant

Using the binomial probability formula, we have:

[tex]P_x = ^nC_xp^x(1-p)^{n-x}[/tex]

For x = 3, the probability is:

[tex]P(x=3) = ^6C_3*0.75^3 * (1-0.75)^{6-3}[/tex]

[tex]P(x=3) = 20*0.75^3 * 0.25^3[/tex]

[tex]P(x=3) = 0.1318[/tex]

Step-by-step explanation:

given

6n - 10

Take 2 as common then

2 ( 3n - 5 )

hope it helps  :)

Answer:

2(3n-5)

Step-by-step explanation:

You need to find the highest common factor (2 in this case).

When the word factorise is mentioned that means there has to be brackets in your answer.

After the highest common factor is found then divide the numbers by it. for example, 6÷2 and -10÷2.

Hope that helps!!

Answer:

51

Step-by-step explanation:

There are 14 movie theaters, and 3 exits each.

You can multiply 14 by 3 to get the number of exits in the movie theaters combined.

Next, the food area has 9, so you add 9 to the 42.

42 + 9 = 51.

Hope this helps!

Answer:

there are 51 exits

Answer:

each bottle of juice costs $2.34

Step-by-step explanation:

2.74+10x=26.14

10x=26.14-2.74

10x=23.40

x=23.40/10

x=2.34

If the sum of the two smallest sides of a triangle are less than the third side, then the triangle cannot be constructed, since the sides would not be able to touch. However, since 35+120 is greater 125, this triangle can be formed

Answer:

x = 20°

y = 160°

z = 160°

Step-by-step explanation:

x = 20°

(Measure of arc is equal to the measure of its corresponding central angle)

z = 180° - 20°

(Linear pair angles)

z = 160°

y = z

(Measure of arc is equal to the measure of its corresponding central angle)

y = 160°

the answer is 659 because if x = 5 that means 25x25 = 625

and if y = 2 then 625 + 52 = 677

and then 677-18 = 659

Answer:

Step-by-step explanation:

70(10/100)=7 broken cookies.

7/70=1/10 is the fraction broken

(70-7)/70=63/70 is the fraction remaining whole

Answer:

(a) 1/7 are broken

(b) 6/7 remain whole

Step-by-step explanation:

70 is a nice number to deal with in terms of percentages and fractions. If 10% of the cookies are broken, do 10/70. That fraction simplified gets you 1/7. To find the remaining whole cookies. Do 7/7 - 1/7 = 6/7 (or if you already know that in your head that works too)

Answer:

(x+5) and (x-7).

Step-by-step explanation:

The given equation is :

[tex]x^2-2x-35[/tex]

We need to write it in factored form.

We have to find two number such that their sum is 2 and product is 35.

We know that,

7×5 = 35 and 7+(-5) = 2

So,

[tex]x^2-2x-35=x^2-7x+5x-35\\\\=x(x-7)+5(x-7)\\\\=(x+5)(x-7)[/tex]

Hence, the required factors are (x+5) and (x-7).

Answer:

b. 36 years

Step-by-step explanation:

Today

Nirmala = x years

Rahul = 3x years

In 13 years

Nirmala = 3x + 13 years

Rahul = 2(x+13) - 1

3x + 13 = 2(x+13) - 1

3x + 13 = 2x + 26 - 1

3x + 13 = 2x + 25

3x - 2x = 25 - 13

x = 12

Nirmala = x years

= 12 years

Rahul = 3x years

= 3(12)

= 36 years

The age of Rahul today is 36 years

Answer:

C) (8, 11)

Step-by-step explanation:

8+3=11.

Answer:

5 +40x

Step-by-step explanation:

Distributive property:a*(b +c) =(a*b) + (a*c)

-3 - 8( -5x - 1) = -3 + (-5x)*(-8) + (-1) * (-8)

                     = -3 + 40x + 8

                     = -3 + 8 + 40x      {combine like terms}

                     = 5 + 40x

Answer:

The cost of the mug is of $6.50.

Step-by-step explanation:

The cost of the mug and r refills is given by the following equation:

[tex]C(r) = 2.3r + 6.5[/tex]

Cost of the mug:

The cost of the mug is found when no refills are bought, that is, C when [tex]r = 0[/tex], which is [tex]C(0)[/tex]

[tex]C(0) = 2.3*0 + 6.5 = 6.5[/tex]

The cost of the mug is of $6.50.

Answer:

D. 4 centimeters, 6 centimeters, 9 centimeters

Step-by-step explanation:

Considering side length for forming a triangle, most of the time it is about Triangle Inequality Theorem, which for 3 sides length a,b,c, it must satisfy the following set of inequalities:  

[tex]a+b>c\\a+c>b\\b+c>a[/tex]

By checking each of them only D satisfy:

[tex]4+6=10>9\\6+9=15>4\\9+4=13>6[/tex]

For simplicity you only have to check if the two shortest sides add up to be larger than the longest side:

[tex]4+6>9[/tex]

Answer:

6.75 ft^2

Step-by-step explanation:

The area of the seat can be calculated as follows

a + b/2 × h

6+3/2 × 1.5

9/2 × 1.5

4.5× 1.5

= 6.75 ft^2

Hence the area of the seat is 6.75ft^2
