Answer:
$9
Step-by-step explanation:
Since the question only asks for small ones, we only need to focus on 1.80 and 5. Multiple them. 1.80×5 and we get 9. 1.80×5=9
How do you do a negative power?
Answer:
A negative exponent is defined as the multiplicative inverse of the base, raised to the power which is opposite to the given power. In simple words, we write the reciprocal of the number and then solve it like positive exponents. For example, (2/3)-2 can be written as (3/2)2.

What's the approximate length of an arc with radius 3 miles and central angle of 45
Length of the arc of a circle is given by,
Length of arc = [tex]\frac{\theta}{360^{\circ}}(2\pi r)[/tex]Here, θ is the central angle subtended by the arc
r = Radius of circle
By using this expression, approximate length of the arc with radius 3 miles will be 2.36 miles.
If the radius of circle = 3 miles
Central angle subtended by the arc = 45°
Therefore, length of the arc = [tex]\frac{45^{\circ}}{360^{\circ}}(2\pi )(3)[/tex]
= 2.36 miles
Length of the arc of the given circle will be 2.36 miles.

A certain stock's price, S (t), can be modeled by the polynomial function S (t) = t^4 – 12t^3 + 52t^2 – 96t + 64, where t represents the month in 2021. In which month will the price of the stock have a local maximum?
February
March
April
May
Answer:
April
Step-by-step explanation:
To solve, you find the maximum of the polynomial function. You can do this by either graphing or plugging in the values in a T chart.
I graphed the function, provided down below.
As you can see, the highest value in the graph is the middle most point, aka (4,1). Count down the months of the year to 4, and you'll find that April is the 4th month of the year.
Using derivative concepts, it is found that the function has a local maximum in March.
--------------------
A function S(t) has local maximums or minimums at points in which the derivative is 0.If the function goes from increasing(positive derivative) to decreasing(negative derivative), it has a local maximum.The function is:
[tex]S(t) = t^4 - 12t^3 + 52t^2 - 96t + 64[/tex]
Which has the following derivative:
[tex]S^{\prime}(t) = 4t^3 - 36t^2 + 104t - 96[/tex]
Now, for each month, it has to be tested the derivative, verifying if it's zero.--------------------
February is the 2nd month, thus, the derivative is:
[tex]S^{\prime}(2) = 4(2)^3 - 36(2)^2 + 104(2) - 96 = 0[/tex]
Now, we have to test a value less than 2, and one greater than two, to check if it goes from increasing to decreasing, that is, derivative goes from positive to negative.
[tex]S^{\prime}(1.5) = 4(1.5)^3 - 36(1.5)^2 + 104(1.5) - 96 = -7.5[/tex]
[tex]S^{\prime}(2.5) = 4(2.5)^3 - 36(2.5)^2 + 104(2.5) - 96 = 1.5[/tex]
From negative to positive, thus, a local minimum in February.
--------------------
March is the 3rd month, thus, the derivative is:
[tex]S^{\prime}(3) = 4(3)^3 - 36(3)^2 + 104(3) - 96 = 0[/tex]
Testing before and after:
[tex]S^{\prime}(2.5) = 4(2.5)^3 - 36(2.5)^2 + 104(2.5) - 96 = 1.5[/tex]
[tex]S^{\prime}(3.5) = 4(3.5)^3 - 36(3.5)^2 + 104(3.5) - 96 = -1.5[/tex]
From positive to negative, thus, it has a local maximum in March.

The mean length of 7 planks of wood is 1.35m. When an extra plank of wood is added, the mean length of a plank of wood increase to 1.4m. the length of the extra plank of wood that was added is Select one a. 2. 4 b. 1 C. 1.25 d. 1.75V
Answer: Hello There!................
Mean = Sum of observation / total number of observation
Mean = 1.35m
1.35 = Sum of length of 7 wood planks/ 7
1.35*7 = Sum of the length of 7 wood planks
9.45 = Sum of the length of 7 wood planks
Let the length of extra added wood plank = x
So,
(Sum of the length of 7 wood planks + x) / 8 = 1.4m
(9.45 + x) / 8 = 1.4
9.45 + x = 1.4 * 8
9.45 + x = 11.2
x = 11.2- 9.45
= 1.75
So,
The length of extra added wood plank = 1.75m

Since loan payments of $ 1725 due today, $ 510 due in 75 days and $ 655 due in 323 days are to be combined into a single payment in 115 days, to determine what is the single payment if money is worth 8.5% and focal date is 115 days the following calculation must be made, offsetting the days in advance with the days in which the payment is late:
8.5 / 365 x 115 = 2.6780 8.5 / 365 x (115 - 75) = 0.9315 8.5 / 365 x (115 - 323) = -4.8438 (1725 x 1.02678) + (510 x 1.009315) + (655 x (1 - 0.048438) = X 1,771.20 + 514.75 + 655 x 0.9515 = X 2,285.95 + 623.23 = X 2,909.18 = XTherefore, the single payment would be $ 2,909.18.

Answer:
Step-by-step explanation:
since loan payments of $1725 due today. $510 due in 75 days and $655 due in 323 days are to be combined into single payment in 115 days.
now,
First, we need to calculate the present value of each payment using the given interest rate and the focal date of 115 days from now.
formula
The formula to calculate the single payment due 115 days from now is:
Single Payment = (PV1 / (1 + r1*(t1/365))) + (PV2 / (1 + r2*(t2/365))) + (PV3 / (1 + r3*(t3/365))) / (1 + r4*(t4/365))
Where:
- PV1, PV2, and PV3 are the present values of the three payments due today, in 75 days, and in 323 days, respectively.
- r1, r2, and r3 are the interest rates for each payment period.
- t1, t2, and t3 are the time periods in days between the payment due date and the focal date of 115 days from now.
- r4 is the interest rate for the period between the focal date and the payment due date of the single payment.
- t4 is the time period in days between the focal date and the payment due date of the single payment.
The present value of the payment due today is:
PV1 = 1725 / (1 + 0.085*(115/365)) = $1666.27
The present value of the payment due in 75 days is:
PV2 = 510 / (1 + 0.085*(75/365)) = $496.16
The present value of the payment due in 323 days is:
PV3 = 655 / (1 + 0.085*(323/365)) = $585.92
Next, we add up the present values of the three payments to get the total present value:
PV = PV1 + PV2 + PV3 = $2748.35
Finally, we calculate the single payment due 115 days from now by discounting the total present value to the focal date of 115 days from now:
Single Payment = PV / (1 + 0.085*(115/365)) = $2909.18
Therefore, the single payment due 115 days from now is $2909.18.
