Answer:

the answer to this question should be 1004.8 because first you need to use this formula to find the volume of a cylinder which is V=TTr^2h so remember the radius is half of the diameter.

So the half of 8 is 4 so 4 is the radius but remember that 4 is to the power of 2 in the exponent so the answer should be 16 because you multiplied 4 times 4 equals 16.

Then we need to multiplied 16 times 3.14 and 20 and when we do that we get an answer of 1,004.8 so 1004.8 feet^3 is the correct answer.

Step-by-step explanation: :DDDDD give brainliest to the first people that answer first than me if you want and have a great day.

Which Expression Can Be Used To Determine the nth term in the pattern below<br> 20,25,30,35,40
maw [93]

Answer:

see explanation

Step-by-step explanation:

These are the terms of an arithmetic sequence with n th term

a_{n} = a + (n - 1)d

where a is the first term and d the common difference

d = 25 - 20 = 30 - 25 = 5 and a = 20, hence

a_{n} = 20 + 5(n - 1) = 20 + 5n - 5 = 5n + 15 ← n th term formula

What is the solution of the equation when solved over the complex numbers?<br><br> x^2+27=0
Luba_88 [7]

Answer:

(0,27)

Step-by-step explanation:

x2 + 27 = 0

Solutions based on quadratic formula:

x1  

= −0 − √ 02 − 4×1×27   2×1 = 0 − 6 × √ 3 i   2 ≈ −5.196152i

x2  

= −0 + √ 02 − 4×1×27   2×1 = 0 + 6 × √ 3 i  2 ≈ 5.196152i

Extrema:

Min = (0, 27)

tell whether the angles are adjacent or vertical then find the value of x. can someone help me please i need all the answers
dmitriy555 [2]

Answer:

3. adjacent; 49
4. adjacent; 71

5. verticle; 41

6. adjacent; 14

Step-by-step explanation:

ok basically if the angles are next to each other, then they're adjacent and if they're across from eachother they're verticle.

to find 3:

set both equations equal to each other and solve because verticle angles are equal

to find 4:

add the 2 equations together and set it equal to 180 because adjacent angles add up to equal either a complementary angle or supplementary depending on the problem
