Answer:
t=16.2 years
Step-by-step explanation:
A=p(1+r/n)^nt
A=$20100
P=$6500
r=7%=0.07
n=4
t=?
t=ln(A/P)/n {ln(1+r/n)}
=ln(20100/6500) / 4{ln(1+0.07/4)}
=ln(3.0923)/4{ln(1+0.0175)}
=ln(3.0923)/4{ln(1.0175)}
=1.1289/4(0.0174)
=1.1289/0.0696
=16.23
To the nearest tenth
t=16.2 years

Answer:
a) [tex]x = 10^{18}\,\mu m^{2}[/tex], b) [tex]x = 10^{18}[/tex], c) [tex]x = 10^{21}\,\mu m^{2}[/tex], d) [tex]x = 10^{21}[/tex], e) [tex]x = \frac{1}{10^{21}}[/tex], f) [tex]x = 10^{3}\,nm^{2}[/tex], g) [tex]x = 10^{3}\,nm^{2}[/tex]
Step-by-step explanation:
a) The product of one terameter and one micrometer is:
[tex]x = (1\,tm)\cdot (10^{12}\,\frac{m}{tm})\cdot (10^{6}\,\frac{\mu m}{m} ) \cdot (1\,\mu m)[/tex]
[tex]x = (10^{18}\,\mu m)\cdot (1\,\mu m)[/tex]
[tex]x = 10^{18}\,\mu m^{2}[/tex]
b) The quotient of one terameter and one micrometer is:
[tex]x = \frac{(1\,tm)\cdot (10^{12}\,\frac{m}{tm} )\cdot (10^{6}\,\frac{\mu m}{m} )}{1\,\mu m}[/tex]
[tex]x = \frac{10^{18}\,\mu m}{1\,\mu m}[/tex]
[tex]x = 10^{18}[/tex]
c) The product of terameter and one nanometer is:
[tex]x = (1\,tm)\cdot (10^{12}\,\frac{m}{tm})\cdot (10^{9}\,\frac{nm}{m} ) \cdot (1\,nm)[/tex]
[tex]x = (10^{21}\,nm)\cdot (1\,nm)[/tex]
[tex]x = 10^{21}\,\mu m^{2}[/tex]
d) The quotient of one terameter and one nanometer is:
[tex]x = \frac{(1\,tm)\cdot (10^{12}\,\frac{m}{tm} )\cdot (10^{9}\,\frac{nm}{m} )}{1\,nm}[/tex]
[tex]x = \frac{10^{21}\,nm}{1\,nm}[/tex]
[tex]x = 10^{21}[/tex]
e) The quotient of one nanometer and one terameter is:
[tex]x = \frac{1\,nm}{(1\,tm)\cdot (10^{12}\,\frac{m}{tm} )\cdot (10^{9}\,\frac{nm}{m} )}[/tex]
[tex]x = \frac{1\,nm}{10^{21}\,nm}[/tex]
[tex]x = \frac{1}{10^{21}}[/tex]
f) The quotient of one nanometer and one micrometer is:
[tex]x = \frac{1\,nm}{(1\,\mu m)\cdot (10^{3}\,\frac{nm}{\mu m} )}[/tex]
[tex]x = \frac{1\,nm}{10^{3}\,nm}[/tex]
[tex]x = \frac{1}{10^{3}}[/tex]
g) The product of one nanometer and one micrometer is:
[tex]x = (1\,nm)\cdot (1\,\mu m)\cdot (10^{3}\,\frac{nm}{\mu m} )[/tex]
[tex]x = 10^{3}\,nm^{2}[/tex]

Can someone please help me out with this? If possible, providing a diagram would be helpful!
Answer:
Cosθ = 0.5145
Sinθ = 0.8575
Secθ = 1.9436
tanθ = 1.667
Step-by-step explanation:
From the figure attached,
Point P(-3, 5) is on the terminal side and AB is the initial side of the angle PAB.
If m∠PAB = θ
AB = [tex]\sqrt{(3)^{2}+(5)^{2}}[/tex]
= [tex]\sqrt{34}[/tex]
= 5.831
Then Cosθ = [tex]\frac{AB}{AP}[/tex] = [tex]\frac{3}{5.831}[/tex]
Cosθ = 0.5145
Sinθ = [tex]\frac{PB}{AP}[/tex]
Sinθ = [tex]\frac{5}{5.831}[/tex]
Sinθ = 0.8575
Secθ = [tex]\frac{1}{\text{Cos}\theta}[/tex]
Secθ = [tex]\frac{1}{0.5145}[/tex]
Secθ = 1.944
tanθ = [tex]\frac{PB}{AB}[/tex]
tanθ = [tex]\frac{5}{3}[/tex]
tanθ = 1.667
How long would it take an investment to triple if it earns 1.5% interest, compounded monthly? Round your answer to the nearest hundredth.
Answer:
73.3 years
Step-by-step explanation:
Use the Compound Amount formula:
A = P(1 + r/n)^(n*t)
Here A = 3P, r = 0.015, n = 12, and so we have:
3 = (1 + 0.015/12)^(12*t). Find t (in years)
3 = (1.00125)^(12*t)
Take the log of both sides. We get:
log 3 = (12*t)(log 1.00125), or 0.47712 = (12*t)(5.425*10^(-4)
0.47712
Solving this for t, we get t = --------------------------- = 73.3 years
(12)(5.425*10^(-4))
find the coordinates of C' after a reflection across the line
y = 1 and then x = 2. Write in the form (a,b)
Part 5a
==============================================================
Explanation:
C is at (0,0). Ignore the other points.
Reflecting over y = 1 lands the point on (0,2) because we move 1 unit up to arrive at the line of reflection, and then we keep going one more unit (same direction) to complete the full reflection transformation. I'll call this point P.
Then we reflect point P over the line x = 2 to arrive at the location Q = (4,2). Note how we moved 2 units to the right to get to the line of reflection, and then keep moving the same direction 2 more units, then we have applied the operation of "reflect over the line x = 2"
So we have started at C = (0,0), moved to P = (0,2) and then finally arrived at the destination Q = (4,2). This is the location of C' as well.
All of this is shown in the diagram below.
50 POINTS!! Use these four expressions to make a hypothesis about the closure property of integers under each operation. Select yes or no for each operation.
Answer:
+ closed
- closed
* closed
÷ not closed
Step-by-step explanation:
When you add integers, you will always get an integer so it is closed under addition
When you subtract integers, you will always get an integer so it is closed under subtraction
When you multiply integers, you will always get an integer so it is closed under multiplication
When you divide integers, you will not always get an integer so it is not closed under division
1/5 = .2 which is not an integer
Answer:
1. Yes
2. Yes
3. Yes
4. No
Step-by-step explanation:
The expression -8 + 5 shows the sum of two integers. This expression has a value of -3. Because -3 is also an integer, the set of integers appears to be closed under addition.
The expression 9 − (-11) shows the difference of two integers. This expression has a value of 20. Because 20 is also an integer, the set of integers appears to be closed under subtraction.
The expression 3 · (-4) shows the product of two integers. This expression has a value of -12. Because -12 is an integer, the set of integers appears to be closed under multiplication.
The expression, -1 ÷ 6, shows the quotient of two integers. This expression has a value -1/6, Because -1/6 is not an integer, the set of integers is not closed under division.

Will the following list have a large or small standard deviation?
7, 6, 5, 8, 9, 1, 0, 4, 3, 2
A) small
B) not enough information
C) large
Answer:
the standared deviation =2.87 so it is small
Step-by-step explanation:
to calculate the standard deviation of those numbers:
1- Work out the Mean (the simple average of the numbers)
(7+6+5+8+9+1+0+4+3+2)/10=4.5
Then for each number: subtract the Mean and square the result.
[(7 - 4.5)^2 + ... + (2 - 4.5)^2]/10=8.25
√8.25=2.87≅3

Answer:
V is inside the circle.
Step-by-step explanation:
We work out the radius of the circle which is the distance between K (0,0) and (6, -4).
Radius = √[(6 - 0)^2 + (-4 - 0)^2]
= √(16 + 36)
= √52.
Now find the distance of point V from K(0,0):
= √((√2-0)^2 + (-7-0)^2]
= √(2 + 49)
= √51.
This is less than the radius of the circle, so V lies inside it.

The area of a rectangle is 252 cm², and the length is 3 less than 2 times the width. Find the dimensions of the rectangle.
Answer:
21cm, 12cm
Step-by-step explanation:
width=x cm
length=2x-3 cm
area= 252cm²
l*b= 252 cm²
(2x-3)(x)=252
2x²-3x= 252
this is how I did it
we need to find the nearest square of the number (it should be lesser than the area)
that is 225, whose square root is 15.
since there is a coefficient to the x², the value of x would be calculate like this 15- (2+1)= 15-3 = 12
x= 12
we can verify it too,
2*(12)² - 3*12=252
288-36=252
252=252
therefore width is 12 cm and width is 2*12-3= 24-3= 21 cm
verify;
21*12= 252
252=252
hence the dimensions are 12 am (width) and 21 cm(length).

Answer:
Function 2.
Step-by-step explanation:
For the first equation, the y-intercept is the 'b' value in the equation
y = mx + b.
In the equation given, b = 5. This is the y-intercept for the equation.
To find the y-intercept, you need to look for the 'y' value at x = 0. Therefore:
In the table, notice that when t = 0, r = 5.25. This is the same as x = 0, y = 5.25. This means that the y-intercept of the table is y = 5.25.
Since 5.25 > 5, function 2 has a greater y intercept.
