Answer:

x^2+6x+9

Step-by-step explanation:

expand the expression

Answer:

a²+2ab+b² =(a+b)²

is your answer

Answer:

c^2=a^2+b^2

c is hypothesis b is abase h is a

15^2=x^2 +12^2

225-144 =x^2

81=x^2

x=9

Answer:

x=15°

Step-by-step explanation:

We can see angle 6x-5 has a corresponding angle above it, which is congruent to it. That angle is supplementary with angle 7x-10. We can tell because it forms a straight angle with it. Supplementary angles add to 180°.

(7x-10)+(6x-5)=180

7x-10+6x-5=180

13x-15=180

13x=195

x=15

Answer:

OC=48

RK=100

Step-by-step explanation:

We can use proportions to find both OC and RK.

[tex]\frac{OK}{KY} =\frac{OC}{RY}[/tex]

[tex]\frac{12}{24} =\frac{OC}{96}[/tex]

[tex]24OC=1152[/tex]

[tex]OC=48[/tex]

[tex]\frac{KC}{RK} =\frac{OK}{KY}[/tex]

[tex]\frac{50}{RK} =\frac{12}{24}[/tex]

[tex]12RK=1200[/tex]

[tex]RK=100[/tex]

Answer:

RK = 100

OC = 48

Step-by-step explanation:

Scale factor = 12/24 = 1/2

1/2 RK = 50

RK = 2* 50

RK = 100

1/2 RY = OC

1/2 * 96 = OC

48 = OC

OC = 48

Answer:

56.73 ft

Step-by-step explanation:

Given:

51° (angle)

73ft (hypotenuse)

With the given information use sin to determine the height of the kite.

sin51° = x/73

solve for x (height)

x= 73*sin51°

x= 56.73ft

Answer:

C) 25.13

Step-by-step explanation:

The formula for circumference is 2(pi)r.

In order to find r, or the radius, we can divide the diameter by 2.

d/2=r

8/2=4

r=4

Plug the radius into the formula

2(pi)4

And finally, plug it into your calculator.

2(pi)4 = ~25.13

Answer:

A. 5.25

Step-by-step explanation:

4.5 + 6 = 10.5

15.75 - 10.5 = 5.25

4.5 + 6 + 5.25 = 15.75

Answer:

Shirt : Pant = 2 : 3 ,  & Pant : Shirt = 3 : 2 , Linear model can be used.

Step-by-step explanation:

Ratio of ' Number of shirts sold : Number of items sold' = 2 : 5

Let the common ratio be = x

Then, number of shirts sold = 2x. And, number of total items sold = 5x.

So, number of pants sold = Number of items sold - number of shirts sold = 5x - 2x = 3x

So, shirt to pant ratio = 2x / 3x = 2 : 3 .And,  pant to shirt ratio = 3 : 2

This model can be shown in linear equation, as all are linear powered.

Step-by-step explanation:

Answer:

Solution given:

x(w – 1) + (W – 1)

distribute it:

xw-x+w-1

xw+w-x-1

take common from each term

w(x+1)-1(x+1)

take common again

(x+1)(w-1)

the factored form of x(w – 1) + (W – 1) is (x+1)(w-1).

Answer:

David's height is 57 inches.

Step-by-step explanation:

x/11=55

x=605

x/10=54.8

x=548

605-548=57

Answer:

57 inches

Step-by-step explanation:

undo the problem

55 x 11 = 605

54.4 x 10 = 548

605 - 548 = 57

hope I helped :)

==========================================================

Explanation:

There are 30 days in April. Since it rained 9 of those days, the empirical probability of it raining in April is 9/30 = (3*3)/(3*10) = 3/10.

If we assume that the same conditions (ie weather patterns) hold for May, then the empirical probability of it raining in May is also 3/10. By "raining in May", I mean specifically raining on a certain day of that month.

The empirical probability of it not raining on the first of May is therefore...

1 - (probability it rains)

1 - (3/10)

(10/10) - (3/10)

(10-3)/10

7/10

We can think of it like if we had a 10 day period, and 3 of those days it rains while the remaining 7 it does not rain.

Step-by-step explanation:

I think the choose 3 (g , h ,f )

Answer:

D for the first one and D for the second one.

Step-by-step explanation:

Step-by-step explanation:

Okay, the first step is to rewrite this equation in "vertex form." You can search that up but it's basically just (h/k).

y = ( x − 1) 2 + 3

Now, we are going to use the vertex form, "y = a (x - h)2 + k, to get the values of a, h, and k.

By using the form we get 1 for the value a, 1 for the value h, and 3 for the value k.

1 = a

1 = h

3 = k

Becuse the value of a is positive, the parabola opens up!  (A parabola is the U shaped line in a graph, so that opens up.)

Now, we find the vertex (h,k)

which is (1,3)

Now we find the p from the vertex to the focus.  (vertext the top, focus one of the points.)

Follow this formula to find the distance from the vertex to a focus by using this formula

1/4a.

Now we just gonna substitue 1 for a, since we know that 1 equals a above ^

1/4 * 1

Solving that, we got a nice little 1/4.

Next we find the focus

"Find the focus.

The focus of a parabola can be found by adding p to the y-coordinate k if the parabola opens up or down.

(h,k+p)

Substitute the known values of h, p, and k into the formula and simplify.

(1,134)

Find the axis of symmetry by finding the line that passes through the vertex and the focus.

x=1

Find the directrix.

y=114

Use the properties of the parabola to analyze and graph the parabola.

Direction: Opens Up

Vertex: (1,3)

Focus: (1,134)

Axis of Symmetry: x=1

Directrix: y=114

Select a few x values, and plug them into the equation to find the corresponding y values. The x values should be selected around the vertex.

xy−1704132437

Graph the parabola using its properties and the selected points.

Direction: Opens Up

Vertex: (1,3)

Focus: (1,134)

Axis of Symmetry: x=1

Directrix: y=114
