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]

Answer:
=z ^(-11) + ^(-15)
= z ^ -26
Answer:
z^-11 times z^-15 = z^-26
Step-by-step explanation:
According to exponential properties, multiplying two numbers that have exponents with the same bases should be added.
Negative exponents mean to go from a^-x to 1/a^x.
Using these properties, we evaluate the expression.
Both terms have the same base, z, so we can go ahead and add the exponents.
-11 + -15 = -26
z^-11 * z^-15 = z^-26
Because the instructions specifically say to leave it in z^n form, our answer is z^-26.

(08.05 MC)The following box plot shows the number of books sold each day at a bookstore for 40 days. How many days did the bookstore sell 2 to 12 books?
Answer:
20 days
Step-by-step explanation:
Number of books sold each day for 40 days :
The first quartile (Q1) = 2
For the 25% of the days = 2 books were sold
Hence 0.25 * 40 = 10 days, 2 books or less were sold
The upper quartile (Q3) = 12 books
For up to 75% of the days = 0.75 * 40 = 30 days ; 12 books or less were sold
To obtain the number of books sold between 2 and 12 ; we subtract :
(30 days - 10 days) = 20 days
Answer:
20

What is y=4x-29
x+y=1
MUST SHOW WORK!!
Answer:
Hope this helps!! (x,y)=(6,-5)
Answer:
y=-5
x=6
Step-by-step explanation:
substitute y=4x -29 into the equation x+y=1.
x+ 4x-29 = 1
combine like terms
5x-29=1
add 29 to both sides
5x=30
divide by 5
x=6
plug 6 into x in the original equation
y=4(6) - 29
y=24-29
y= -5
Find all the real zeros of the function
f(x) = 2x3 - 19x2 + 38x + 24 given that x-4 is a factor.
Answer:
Zeroes: x=4, x=-1/2, and x=6
Step-by-step explanation:
Use Synthetic Division where x-4=0 to find another factor:
4 | 2 -19 +38 +24
___8_-44_-24
2 -11 -6 | 0
So far, your two factors are x-4 and 2x^2-11x-6.
We can actually factor 2x^2-11x-6 into (2x+1)(x-6), so we have three factors which are (x-4), (2x+1), and (x-6)!
By the Zero Product Property, x=4, x=-1/2, and x=6 are your zeroes.

Nancy received a birthday gift of $35. She decided to
use this money to start a savings account and then
deposited $5 into the account every week.
Which equation represents the relationship between
w, the number of weeks she has saved, and s, the
total amount saved?
s = 35W - 5
s= 5W - 35
S = 35W + 5
s = 5W + 35

A kite is staked to the ground and blowing in the wind. It currently has a string let out to a length of 100 meters. The string makes an angle of elevation of 39° with the ground. To the nearest tenth of a meter, determine the altitude (height) of the kite.
Answer:
62.9 m
Step-by-step explanation:
We solve the above question using the Trigonometric function of Sine
sin θ =Opposite/Hypotenuse
Opposite = Altitude/Height of the kite = ?
Hypotenuse = Length of the string = 100m
θ = Angle of elevation = 39°
Hence,
sin 39 = x/100m
Cross Multiply
x = sin 39 × 100m
x = 62.932039105 m
Approximately to the nearest tenth = 62.9 m
Therefore, the altitude (height) of the kite is 62.9 m

What is the volume of a marble sphere that has a radius of 12 millimeters? Express the answer in terms of π
What is the area of the figure?
Answer:
252 square inches.
Step-by-step explanation:
Split the Cube into three shapes.
You can make the biggest cube 12 by 15 and mutliply those together.
That would be 180.
Now you are left with 2 other smaller cubes.
3 * 6 = 18
6 times 9 = 54
The Final Answer is 252 square inches.
Convert (4, 3π/2) to rectangular form.
A) (0,4)
B) (0, -4)
C) (-4,0)
D) (4,0)
Answer:
(0, -4)
Step-by-step explanation:
The rectangular form is expressed as;
x = rcos theta
y = rsin theta
Given the coordinate (4, 3π/2)
r = 4
theta = 3π/2
Substitute
x = 4cos3π/2
x = 4cos270
x = 4(0)
x = 0
y= 4sin3π/2
y = 4sin270
y = 4(-1)
y = -4
Hence the required coordinate is (0, -4)
What is the equation of the line that passes through (-1,-4) and (2,5)
A. y+1=3(x+4)
B. y+4=-3(x+1)
C. y+4=3(x+1)
D. y-4=-3(x-1)
Answer:
c) y+4=3(x+1)
Step-by-step explanation:
Answer:
C. [tex]y+4=3(x+1)[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
All the given equations are in point-slope form: [tex]y-y_1=m(x-x_1)[/tex] where m is the slope and the given point is [tex](x_1,y_1)[/tex]1) Determine the slope of the line
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the points (-1,-4) and (2,5)
[tex]=\frac{5-(-4)}{2-(-1)}\\=\frac{5+4}{2+1}\\=\frac{9}{3}\\=3[/tex]
Therefore, the slope of the line is 3. Plug this into [tex]y-y_1=m(x-x_1)[/tex] :
[tex]y-y_1=3(x-x_1)[/tex]
2) Plug the point (-1,-4) into [tex]y-y_1=3(x-x_1)[/tex]
[tex]y-(-4)=3(x-(-1))\\y+4=3(x+1)[/tex]
Therefore, the correct answer is C.
I hope this helps!

Ben needs to read 450 pages of his book for school. If he has five days to finish, how many pages should he read each day?
Answer: 90
Step-by-step explanation:
450/5 or 450 divided by 5
you can work this out by figuring out 45/5 which is 9
so 450/5 equals 90
he should read 90 pages per day
Answer:
90
Step-by-step explanation:
Because if you divide the pages into the 5 day it would be 90
450 divide by 5 = 90

17. In the 1600s, a blacksmith could make a living by hand-forging horseshoes and nails. A diligent blacksmith could
make one horseshoe in 12 minutes and a nail in 1 minute. In the 1600s, it would take the blacksmith 210
minutes to complete a particular job. With advances in technology, the blacksmith was able to make a
horseshoe in 9 minutes and a nail in 40 seconds, and could complete the same job in 155 minutes. In the
equations below, h represents the number of horseshoes in the job, and n represents the number of nails in
the job.
12h + n = 210
2n
9h +
= 155
How many nails were in the job the blacksmith completed?
Answer: It would be 30
