Answer:

  • 8\sqrt{13} units

Step-by-step explanation:

<u>We know that:</u>

  • P = 4a

<u>We can find one side by distance formula:</u>

  • a = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}
  • a = \sqrt{(10 - 4)^2+(-5+9)^2} = \sqrt{36+16} = \sqrt{52} = 2\sqrt{13}

<u>Then the perimeter is:</u>

  • P = 4*2\sqrt{13} = 8\sqrt{13} units

Given the diagram below, what is cos(45*)? <br><br> A.<br><br><br> B.<br><br><br> C.<br><br><br> D.
alina1380 [7]

Answer:

The answer is option B

Step-by-step explanation:

To find cos 45° we must first find the adjacent and the hypotenuse

Let the adjacent be x

Let the hypotenuse be h

To find the adjacent we use tan

tan ∅ = opposite / adjacent

From the question

the opposite is 9

So we have

tan 45 = 9 / x

x tan 45 = 9

but tan 45 = 1

x = 9

Since we have the adjacent we use Pythagoras theorem to find the hypotenuse

That's

h² = 9² + 9²

h² = 81 + 81

h² = 162

h = √162

h = 9√2

Now use the formula for cosine

cos∅ = adjacent / hypotenuse

The adjacent is 9

The hypotenuse is 9√2

So we have

cos 45 = 9/9√2

We have the final answer as

<h3 /><h3>cos 45 = 1 / √2</h3>

Hope this helps you

What is the volume of a sphere with a diameter of 8 m use 3.14 for pie round your answer to the nearest hundredth
deff fn [24]

Volume of the sphere is 300 m³

Step-by-step explanation:

  • Step 1: Calculate volume of the sphere using the formula V = 4/3πr³, where r = d/2 = 4m

⇒ V = 4/3 × 3.14 × 4³ = 267.95 = 300 m³ (rounding off to the nearest hundredth)
