Answer:

2 + m- 1 + m

Step-by-step explanation:

3m +1 -m

Combine like terms

3m-m +1

2m +1

We can split the m's

m+m +1

And we can rewrite 1 as 2-1

m+m+2-1

m+2+m-1

Rearranging the order

Type the correct answer in the box. Round off your answer to the nearest integer.
Mkey [24]

Answer:

∠ p ≈ 59°

Step-by-step explanation:

Using Pythagoras' identity in right triangle ABD to find DB

DB² = 5² + 6² = 25 + 36 = 61 ( take square root of both sides )

DB = \sqrt{61}

---------------------------------------

Using the cosine ratio in right triangle DBC

cos p = \frac{adjacent}{hypotenuse} = \frac{DC}{DB} = \frac{4}{\sqrt{61} } , thus

p = cos^{-1} ( \frac{4}{\sqrt{61} } ) ≈ 59°

A sphere has a volume of 36π m3. Find the surface area of the sphere.
shusha [124]
V=4/3πr^3
36π=4/3πr^3
3/4(36π)=(4/3πr^3)3/4
27π=πr^3
π(27π)=r^3
27=r^3
square root
r=3
s.a=4πr^2
s.a=4π(3^2)
s.a=4π(9)
