Answer:
[tex]r=0.0718[/tex]. The closest value from your given choices is C)r=0.69
Step-by-step explanation:
To solve this we are using the standard exponential growth equation:
[tex]f(t)=A(1+r)^t[/tex]
where
[tex]f(t)[/tex] is the final population after [tex]t[/tex] years
[tex]A[/tex] is the initial population
[tex]r[/tex] is the growth rate in decimal form
[tex]t[/tex] is the time in years
We know from our problem that the initial population is 5000, the final population is 10000, and the time is 10 years, so [tex]A=5000[/tex], [tex]f(t)=10000[/tex], and [tex]t=10[/tex].
Let's replace the values and solve for [tex]r[/tex]:
[tex]f(t)=A(1+r)^t[/tex]
[tex]10000=5000(1+r)^{10}[/tex]
Divide both sides by 5000
[tex]\frac{10000}{5000} =(1+r)^{10}[/tex]
[tex]2=(1+r)^{10}[/tex]
Take root of 10 to both sides
[tex]\sqrt[10]{2} =\sqrt[10]{(1+r)^{10}}[/tex]
[tex]\sqrt[10]{2} =1+r[/tex]
Subtract 1 from both sides
[tex]\sqrt[10]{2}-1=r[/tex]
[tex]r=\sqrt[10]{2}-1[/tex]
[tex]r=1.0718-1[/tex]
[tex]r=0.0718[/tex]
We can conclude that the growth rate of our exponential equation is [tex]r=0.0718[/tex]. The closest value from your given choices is C)r=0.69

Isabella caries a box up a metal ramp into the back truck. The ramp is 3 meters long and the bottom makes a 32 degree angle with the ground. How many meters is the ground distance between the bottom of the ramp and the back of the truck?
Answer:
2.5 m
Step-by-step explanation:
Consider the ramp, the ground and the back of the lorry to form a right triangle where the ramp is the hypotenuse and the distance from the back of the lorry is the adjacent side, x
Using the cosine ratio in the right triangle
cos32° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{3}[/tex]
Multiply both sides by 3
3 × cos32° = x, hence
x ≈2.5 m
if the federal reserve sells 50,000in treasury bonds to a bank at 6% interest ,what is the immediate effect on the money supply
Answer:
if the federal reserve sells 50,000 in treasury bonds to a bank at 6% interest, the immediate effect on the money supply would be; the money supply would decrease by $50,000
Step-by-step explanation:
if the federal reserve sells 50,000 in treasury bonds to a bank at 6% interest, the immediate effect on the money supply would be; the money supply would decrease by $50,000.
The $50,000 will be transferred to the federal reserves and thus not available to be borrowed by the public.
When the Federal Reserve sells Treasury bonds to a bank, the money supply decreases. This is because the bank, having bought the bonds, will have to reduce its loans to maintain requisite reserves. This is a product of open market operations, a monetary policy tool active within the central banking system.
Explanation:The question you're asking pertains to the field of macroeconomics, specifically monetary policy. You're curious about the effects on the money supply if the Federal Reserve sells $50,000 in Treasury bonds to a bank at 6% interest.
When the Federal Reserve sells these bonds to a bank, it effectively reduces the amount the bank can loan out to customers. The financial institution has to hold a certain amount in reserves, hence, by buying the bonds, it has to reduce its loans to fulfill this requirement. This, therefore, results in an immediate decrease in the money supply.
It's important to note that the Federal Reserve sells bonds to control the flow of money in the economy. This selling of bonds is a type of monetary policy tool called open market operations, which is used to influence the quantity of bank reserves and the level of interest rates.

A fair four-sided number die is marked 1, 2, 2, and 3. A spinner, equally divided into
3 sectors, is marked 3, 4, and 7. Jamie tosses the number die and spins the spinner.
a) Use a possibility diagram to find the probability that the sum of the two resulting
numbers is greater than 5.
b) Use a possibility diagram to find the probability that the product of the two
resulting numbers is odd.
The probability that the sum of the two resulting numbers is greater than 5 is 2/3
The probability that the product of the two resulting numbers is odd is 1/3
How to determine the required probabilities
From the question, we have the following parameters that can be used in our computation:
Die = {1, 2, 2, 4}
Spinner = {3, 4, 7}
The sample space is represented as
Space = {(1, 3), (1, 4), (1, 7), (2, 3), (2, 4), (2, 7), (2, 3), (2, 4), (2, 7), (4, 3), (4, 4), (4, 7)}
For the sum greater than 5, we have the following space
Space = {4, 5, 8, 5, 6, 9, 5, 6, 9, 7, 8, 11}
In the above, we have
Total = 12
Sum greater than 5 = 8
So, this probability is
P = 8/12 = 2/3
For the product resulting in odd numbers, we have the following space
Space = {3, 4, 7, 6, 8, 14, 6, 8, 14, 9, 12, 21}
In the above, we have
Total = 12
Odd results = 4
So, this probability is
P = 4/12 = 1/3
Hence, the probabilities are 2/3 and 1/3

I am paying $60.00 a month for my service. I would like to upgrade to the $80.00 service package because my new employer offers a 20% discount with your company. What would be the cost difference compared to what I am paying now if I upgraded?"
Answer:
The cost difference is $4.
Step-by-step explanation:
Consider the provided information.
I am paying $60 a month for my service.
I would like to upgrade to the $80.00 service package because my new employer offers a 20% discount with your company.
If i get 20% of discount that means i need to pay only 80% of the original amount.
80% of 80 can be calculated as:
[tex]\frac{80}{100}\times 80[/tex]
[tex]0.8\times 80=64[/tex]
Therefore, now i need to pay $4 extra for the upgrade service.
Hence, the cost difference is $4.
the cost difference would be $4 more per month if upgrade is done.
First, let's calculate the cost of the $80 service package with a 20% discount:
[tex]20\%\ of\ 80 = \frac{20}{100} \times 80 = 16[/tex]
Now we need to subtract the discount from the original price = [tex]\$80 - \$16 = \$64[/tex]
Now, let's find the cost difference between the current $60 service and the discounted $64 service. This can be done by subtracting 60 from 64 which gives:
[tex]\$64 - \$60 = \$4[/tex]
Therefore, the cost difference would be $4 more per month if upgrade is done.

Two cars simultaneously started traveling towards each other from two cities, which are 400 miles apart. Car 1 travels 20mph faster than Car 2, and they met in 4 hours. What are the speeds of the cars?
Answer:
The first car travels at 60 mph and the second at 40 mph.
Step-by-step explanation:
Let's represent the speed of the first car as s1 and that of the second car as s1. Then s1 = s2 + 20 reflects the fact that the speed of the first car is 20 mph faster than that of the second car.
The total distance traveled is 400 miles. Since distance = rate times time,
time = distance / rate.
First car: (s1*t) is the distance traveled;
Second car: (s2*t) is the distance traveled.
Adding these two distances together results in 400 miles:
s1*t + s2*t = 400 miles, or
t(s1 + s2) = 400 miles. Let's eliminate s1 by substituting s2+ 20 for it:
t(s2 + 20 + s2) = 400 miles. But we know t: the cars both travel 4 hours.
Thus,
(4 hr)(2s2 + 20) = 400 miles, or
(after dividing both sides by 4 hr)
(2s2 + 20) = 100 miles/hr
Subtracting 20 from both sides:
2s2 = 80, so that s2 = 40 mph.
If s2 = 40 mph, then s1 = s2 + 20 = 60 mph
The first car travels at 60 mph and the second at 40 mph.
Answer:
The first car travels at 60 mph and the second at 40 mph.

From conservation of angular velocity the larger pulley will rotate at a speed of 500 rpm.
What is conservation of angular velocity ?The conservation of angular velocity states that the angular velocity for a conjugate system will be always equal to the angular velocity of a part of the same system.
Mathematically -
r1ω1 = r2ω2 = r3ω3 = ................. = rnωn
where r is the radius of the circular belts, ω is the angular velocity and n is the total number of segments in the conjugate system.
What is the speed of the larger pulley turn in the problem ?Given that a pair of belted pulleys have diameters of 18 in. and 12 in. Also given that the smaller pulley turns at 750 rpm.
The radius of the pulleys are 9 in. and 6 in. respectively.
Let x rpm be the speed of the larger pulley turn.
From conservation of angular velocity, we have
⇒ 6 * 750 = 9 * x
⇒ x = (6 * 750)/9
∴ x = 500 rpm

Answer:
x = 5 and y = 2, or (5,2) (Whichever one you do in class)
Step-by-step explanation:
You should solve this problem using substitution!
First you want to solve for x on this equation, 3x + 2y = 19.
start by subtracting 2y on each side, 3x + 2y(-2y) = 19(-2y). 3x = -2y + 19
Then divide by 3, 3x/3 = (-2y + 19)/3, this would give you x = (-2y + 19)/3
Next you substitute (-2y + 19)/3 in for x in 4x + 3y = -14: 4(-2y/3 + 19/3) + 3y = -14
Then Solve: (See Math Papa Algebra Calculator if you want to know exactly how to solve.) This would give you y = 2
Then substitute the 2: giving you x = 5

a driveway is 40 yards long. about how many meters long is it? HINT: ( a yard is 0.914 meter long)
Answer:
Driveway is 36.57 meters long.
Step-by-step explanation:
We are given the length of a driveway to be 40 yards and we are to find its length in meters.
We know that 1 yard is equal to 0.914 meter long. So we will simply multiply 40 by 0.914 to find the length of the driveway in the meters.
Length of driveway in meters = [tex]40 \times 0.914[/tex] = 36.57 meters
The required, driveway is approximately 36.576 meters long.
To convert yards to meters, we can use the conversion factor: 1 yard = 0.9144 meters.
Given that the driveway is 40 yards long, we can calculate its length in meters by multiplying 40 yards by the conversion factor:
40 yards * 0.9144 meters/yard = 36.576 meters.
Therefore, the driveway is approximately 36.576 meters long.
