Answer:

C= 14.14 yd

Step-by-step explanation:

The circumference of a circle is equal to the equation

C = 2πr

Since the diameter is 4.5, the radius is 2.25.

Plug the radius into the equation, and solve.

C=2π(2.25)

C= 6.283185307(2.25)

C= 14.137

C= 14.14 yd

I hope this helps!

Factor 2m^3-12m^2+18m completely
Nina [5.8K]

Answer:

The answer is A.

Step-by-step explanation:

Firstly, you have to take out the common terms for this expression. In this expression, the common terms ard 2 and m :

2 {m}^{3}  - 12 {m}^{2}  + 18m

= 2( {m}^{3}  - 6 {m}^{2}  + 9m)

= 2m( {m}^{2}  - 6m + 9)

Next you have to factorise the brackets :

{m}^{2}  - 6m + 9

=  {m}^{2}  - 3m - 3m + 9

= m(m - 3) - 3(m - 3)

= (m - 3)(m - 3)

=  {(m - 3)}^{2}

So the final answer is :

2m {(m - 2)}^{2}

-3 + (-8)<br> how can i do this
murzikaleks [220]

Answer: -11

Step-by-step explanation:

+(-8) can be simplified to -8 because when you multiply a positive sign by a negative sign, the outcome is a negative sign. So your problem is -3-8= and the answer is -11 because when two numbers with the same sign are subtracted/added by each other, the numbers just get added and the sign stays the same. If you're still confused, use a number line. Hope this helps!

the price of silver has increased by 15% per year from 2000. in the year 2000, harry bought a silver bowl for $190. which of the
lesya [120]
<h2>Answer</h2>

f(x) = 190(1.15)x

<h2>Explanation</h2>

To solve this, we are going to use the standard exponential function:

f(x)=a(1+b)^x

Where

f(x) is the final price after x years

a is the initial price

b is the rate in decimal form

x is the time in years

We know from our problem that the initial price is $190, so a=190. Now to convert the rate, 15%, to decimal form, we are going to divide it by 100%, so r=\frac{15}{100} =0.15. Let's replace the values:

f(x)=a(1+b)^x

f(x)=190(1+0.15)^x

f(x)=190(1.15)^x
