A person invest $3000 in a bank the bank pays 6.75% interest compounded semi annually to the nearest 10th of a year how long must a person leave the money in the bank until it reaches $6700
Answers
Answer:
It would take 12.1 years.
Step-by-step explanation:
We are given with $3000 invested in bank pays 6.75% interest compounded semi annually to the nearest 10th. We are asked to find the number of years the bank reaches $6700.
Let's use the compound interest formula.
[tex]A= P(1+\frac{r}{n}) ^{nt}[/tex]
We know A=6700
P=3000
r =0.0675
n=2(because compounded semiannually)
t =?( we need to find it)
Plug in the known values into the formula.
[tex]6700=3000(1+\frac{0.0675}{2}) ^{2*t}[/tex]
Simplify and solve for 't'
Divide both sides by 3000
[tex]2.23333= (1.03375)^{2t}[/tex]
Take log on both sides
[tex]log(2.23333) = 2t log(1.03375)[/tex]
Divide both sides by log(1.03375)
24.2067=2t
Divide both sides by 2.
t=12.10...
To round to nearest 10th, we get t=12.1 years.

SO what you do is (4) - 4 to cancel it out then you do the same thing on the other side so (-2)-4=-6 so the equation now is -2x=-6 then you divide -2 to cancel it out and you do the same thing -6 divide by -2 is 3 so the answer is 3

Fernando built a robot to filter air and water efficiently. He expects the robot to filter more than 512 liters
of air and water while using less than 9 Joules of energy.
A represents the number of minutes the robot filters air, and W represents the number of minutes the
robot filters water.
21A + 14W > 512 represents the number of minutes the robot filters air and water to filter more than
512 liters of air and water.
0.36 A + 0.6W < 9 represents the number of minutes the robot filters air and water while using less
than 9 Joules of energy.
Does the robot meet both of Fernando's expectations by filtering air for 15 minutes and filtering water for
5 minutes?
Answers
The robot does not meet both of Fernando's expectations.
A represents the number of minutes the robot filters air.
W represents the number of minutes the robot filters water.
What is inequality?Inequality is a statement stating two expressions are not equal.
Expectation 1:
21A + 14W > 512
Given A=15 minutes
W=5 minutes
So, 21A + 14W =21*15 +14*5 =370
370<512
So, the robot does not meet Fernando's first expectation.
Expectation 2:
0.36 A + 0.6W < 9
A=15 minutes
W=5 minutes
So, 0.36 A + 0.6W =0.36*15+0.6*5 = 8.4
8.4<9
So, the robot meets Fernando's second expectation.
Hence, the robot does not meet both of Fernando's expectations.

Step-by-step explanation:
∠ AOB = 360° - 264° = 96°
The altitude OM bisects ∠ AOB and the base AB
(a)
∠ MOB = 0.5 × 96° = 48°
Using the cosine ratio in right triangle MOB
cos48° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{OM}{OB}[/tex] = [tex]\frac{18}{r}[/tex] ( OB is the radius r of the circle )
Multiply both sides by r
r × cos48° = 18 ( divide both sides by cos48° )
r = [tex]\frac{18}{cos48}[/tex] ≈ 27 cm ( to the nearest cm )
(b)
Using the tangent ratio in the right triangle MOB
tan48° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{MB}{OM}[/tex] = [tex]\frac{MB}{18}[/tex] ( multiply both sides by 18 )
18 × tan48° = MB then
AB = 2 × MB = 2 × 18 × tan48° = 36 × tan48° ≈ 40 cm ( to nearest cm )
What is the radius of a circle whose area is equal to the sum of the areas of two circles whose radii are 20cm & 21cm?
Answers
Answer:
29
Step-by-step explanation:
20^2 times 3.14= 1256
21^2 times 3.14= 1384.74
the sum of those two is 2640.74
the square root of that is 29
The radius of the circle is 29 cm.
We have the circle whose area is equal to the sum of the areas of two circles whose radii are 20cm & 21cm.
We have to find the radius of the circle.
Suppose you have to find the radius of a circle whose area is equal to the sum of the areas of two circles whose radii are r and R. How will you approach it?Let the radius of the circle be x.
We know that the area of the circle is [tex]\pi r^{2}[/tex]. Then -
[tex]\pi x^{2} =\pi r^{2} +\pi R^{2} \\x=\sqrt{r^{2} + R^{2}} \\[/tex]
Now, in the question given to us -
r = 20cm and R = 21cm and 'x' denotes the radius of the circle we have to find.
Substituting the values in the above formula, we get -
x = [tex]\sqrt{400+441}[/tex]
x =29 cm
Hence, the radius of the circle is 29 cm.

The expression (x^13)(x^6) is equivalent to x^p. What is the value of p?
Answers
Answer:
p=19
Step-by-step explanation:
since the instructions say that ([tex]x^{13}[/tex])([tex]x^{6}[/tex]) is equivalent to [tex]x^{p}[/tex], we can make the equation:
([tex]x^{13}[/tex])([tex]x^{6}[/tex])=[tex]x^{p}[/tex]
now, apply the laws of exponents; [tex]a^{m} * a^{n} =a^{m+n}[/tex]
in that case, since we're multiplying x to the 13th power by x to the 6th, the result is [tex]x^{13+6}[/tex], which is [tex]x^{19}[/tex]
the equation now:
[tex]x^{19}[/tex]=[tex]x^{p}[/tex]
since the exponents are at the same base, we can solve the equation
19=p
so p is 19
