Jillian put $1200 into an account earning 6.5% interest compounded continuously. How long until she doubles her money?
please answer I'll give you five stars and step by step
Answer:
[tex]A= 2400\\P= 1200\\r = 6.5\% = 0.065\\n = 365 \\t = t\\A = P(1 + \frac{r}{n})^{nt}\\\\2400 = 1200(1 +\frac{0.065}{365} )^{365t}\\\\\frac{2400}{1200} = (1.00017808219)^{365t}\\\\(2)^{\frac{1}{365} } = (1.00017808219)^t\\\\\\Taking \ log \ on \ both \ sides\\log(1.00190083768) = t \times log(1.00017808219)\\\\t= \frac{log(1.00190083768)}{log(1.00017808219)} = 10.66\\\\t = 10.7years[/tex]

The area of a circle is
[tex]144\pi \: {m}^{2} [/tex]
What is the diameter of the circle?
Answer:
24
Step-by-step explanation:
The area is calculated by multplying radius (half of diameter) by itself and then with number pi
the area for this circle is given as
144π m^2
144 is the squared form of 12 if the radius is 12 the diameter is 24
Please answer this math question for me.

4 + 3m = 22
subtract 4 from both sides
3m = 18
divide each side by 3
m = 6
The ride is 6 miles.

Sally's income per month is $1500. She wants to create a budget to be able to afford everything. How much can she spend on "fun" things if she has to pay $500 a month for rent, $50 for phone bill, $100 for groceries, $100 for miscellaneous bills. and $300 for a car payment.
Answer:
450$
Step-by-step explanation:
So lets add otgether everything that she NEEDS to buy, to see how much of 1500$ she can use on what she WANTS to buy.
So:
500+50+100+100+300
=
1050
This is the total cost of what she NEEDS to buy
Now lets subtract this from her income:
1500-1050
=
450
So we now know that the amount of money she has left to spend on what she WANTS is 450$
Hope this helps! :)

Step-by-step explanation:
So, there are 16 ounces in a pound.
There are 3 1.2, or 3.5 pounds.
To find the total ounces, lets multiply the ounces per pound by the total amount of pounds:
16*3.5
=
56
So your answer is 56!

If f(x)=x^2-2x+11, find f (-2)
Answer: f( -2) = 19
Step-by-step explanation:
plug '-2' into every place 'x' is in
so the new equation would be
f(-2) = (-2)^2 - 2(-2) + 11
and now solve :)
f ( -2) = 4 - ( -4) + 11
f (-2) = 4 + 4 + 11
f ( -2 ) = 19

Answer:
a = [tex]4\sqrt{3}[/tex]
b= 4
Step-by-step explanation:
It's a 30-60-90 triangle based on the given picture. A right triangle too
Use sine, cosine, and tangent to solve for the side.
To find b, you can use sin(30) = b/8 because sin(angle) = opposite/hypotenuse.
OR you can use the rule for 30-60-90 triangle, which is x for short leg, 2x for hypotenuse, and [tex]x\sqrt{3}[/tex] for long leg
So either way, b = 4
To find a, you can use cos(30) = a/8 because cos(angle) = adjacent/hypotenuse.
OR you can use the same rule, 30-60-90 triangle to save time
a will end up = [tex]4\sqrt{3}[/tex]

You won $1000 in a radio contest. If you invest it in an account that pays 4.5% interest compounded semiannually, what will be your balance after 4 years?
please answer I'll give you five stars
Answer:
[tex]A= P( 1 + \frac{r}{n})^{nt}\\[/tex]
P = 1000
r = 4.5% = 0.045
n = semi annually = 2
t = 4
[tex]A= 1000( 1 + \frac{0.045}{2} )^8 =1000(1 +0.0225)^8= \$ 1194.83[/tex]
