Answer:

y = 2x + 3

Step-by-step explanation:

Going from point (0, 3) to point (1, 5), you go 2 units up and 1 unit right. That means the rise is 2, and the run is 1.

slope = rise/run = 2/1 = 2

The slope is 2.

y = 2x + b has a slope of 2.

Now we need b.

Looking at the graph, we see that the y-intercept of the line is point (0, 3), so b = 3.

The equation is

y = 2x + 3

If the radius of a circle is 10 feet, how long is the arc subtended by an angle measuring 81°?

Kaylis [27]

The length of an arc, L = theta/360 * 2 * pie * r Where theta = 81 and r = 10ft = 3.048m So length = 81/360 * 2 * pie * 3.048 L = * 0.225 * 2 * pie * 3.048 L = 1.37 * pie L = pie. Option A

Marizza181 [45]

Given:

$\text{ Dimension = 3}\times5$

Sol:

Area of picture is:

$\begin{gathered} =\text{ length}\times\text{ Width} \\ \\ =15 \end{gathered}$

If the cost $10 per square inch then price of 15 square inch is:

$\begin{gathered} =15\times10 \\ \\ =150 \end{gathered}$

If the quadruple of dimension that mean:

$\begin{gathered} \text{ l ength = 4 length} \\ \\ Width\text{ = 4 width} \end{gathered}$

So area is:

$\begin{gathered} A=4\text{ length}\times4\text{ Width} \\ \\ A=4(15) \\ \\ A=60 \end{gathered}$

So price is:

$\begin{gathered} =60\times10 \\ \\ =600 \end{gathered}$

adam is going to cook a turkey for 14 people he want 3/4lb of turkey per person 1lb =450g how much would a turkey in kg would I

klemol [59]

In this question, let us first note down all the important information's that have been provided in the question.
The number of people that Adam is cooking for = 14
Amount of turkey required per person = 3/4 pounds
Now
Total amount of turkey required by Adam to cook for 14 people = (3/4) * 14
   = 21/2
So 21/2 pound of turkey is required by Adam to cook for 14 people. This weight of turkey has to be converted to gram first and then to kilogram.
We already know
1 lb = 450 g
Then
21/2 lb = 450 * (21/2) gram
      = 225 * 21
      = 4721 gram
Now again we know
1000 g = 1 kg
4721 gm = (4721/1000) kg
   = 4.721 kg
So Adam needs to have a turkey weighing 4.721 gram to cook for the 14 people. I hope the procedure is clear to you.

Answer:

30 m/s

Step-by-step explanation:

p = mv

momentum = mass × velocity

mass is 2kg

substitute in the equation

60 = 2v

v= 30m/s
