Answer:

C. -4n + 8

Step-by-step explanation:

Try the formulas and see which works.

The common difference is -4, so the coefficient of n in the explicit formula is -4. Every term is divisible by 4, so there won't be 3 anywhere in the formula.

-4·1 +8 = 4

-4·2 +8 = 0

-4·3 +8 = -4

-4·4 +8 = -8

The formula -4n+8 reproduces the sequence exactly.

Multiply (2.0 ⋅ 10^−4) ⋅ (3.1 ⋅ 10^−20). Express the answer in scientific notation

ehidna [41]

Multiply the constants then multiply the base 10 numbers.
2* 3.1 = 6.2
10^-4 * 10^-20 = 10^-24
Now put back together.
6.2 * 10^-24

A princess hat for a costume is shaped like a cone. The base of the cone is 12 in across and the height is 8

LenaWriter [7]

Answer:

Part a) The drawn in the attached figure

Part b)The slant height of the outside edge is $x=10\ in$

Step-by-step explanation:

Part a) The drawn in the attached figure

Part b) What is the slant height of the outside edge?

we have that

The diameter of the base of the cone is 12 in

$r=12/2=6\ in$ ----> the radius is half the diameter

$h=8\ in$

Applying the Pythagoras Theorem find the slant height x

$x^{2}=r^{2}+h^{2}$

substitute the values

$x^{2}=6^{2}+8^{2}$

$x^{2}=100$

$x=10\ in$

Anyone HElp!

V125BC [204]

S= 2 (LW) +2 (LH) +2(WH)
then we can plug in the values we know! :)
S= 2(2*3) +2(2*4) +2(3*4)
Then we can do some simplifying
S= 2(6) +2(8) +2(12)
Then some more multiplying...
S=12 +16 +24
Then lastly, addition
S= 52 cm^2

2/3 of the product of 3/8 and 16

kakasveta [241]

Hi there!

To solve this problem, we should first find the product of 3/8 and 16 and multiply the solution by 2/3.

Let's find the product first.

3/8 × 16 = 48/8

Simplify.

48/8 = 48 ÷ 8 = 6

Now, we find 2/3 of 6.

6 ÷ 3 × 2 = 2 × 2 = 4

So, your answer is 4.

Hope this helps!
