The solution for the given decimal multiplication is 0.025.
What are decimal numbers and how do you multiply them?To multiply two decimal numbers, first multiply the values without the decimal points.
The digits in the factors that follow the decimal point should now be added together.
Following that, the dot should be placed in the product so that it has the same number of digits as the total number of factors.
If there are more decimal places than digits in the number, place zeroes immediately after the dot.
If there are more decimal places present compared to digits in the product, fill the decimal places with zeroes immediately after the dot.
For the given question, multiply -5 * -5 = 25
Now the total digits after the decimal point in factors are 3.
But there are only 2 digits in 25.
So fill the decimal place with a zero.
Therefore the product of given decimal numbers is 0.025.

Determine the average rate of change of B from t = 0 $ to t = 332 s. Time (s) Concentration of A (M) 0 0.670 166 0.415 332 0.160
A -> 2B rateB =__________________ M/s
Answers
The rate of B is -0.003072 M/s.
The average rate of change is a measure of how much a quantity changes over a certain period of time. In this case, we are looking at the concentration of B, and we want to know how much it changes over the time interval from 0 to 332 seconds. To calculate this, we first need to determine the initial and final concentrations of B at these two points in time.
From the given data, we know that
the initial concentration of B at t = 0 is 0.670 Mthe final concentration of B at t = 332 s is 0.160 M.Once we have these values, we can calculate the change in concentration of B by subtracting the initial concentration from the final concentration: 0.160 M - 0.670 M = -0.510 M. This tells us that the concentration of B decreases by 0.510 M over the time interval from 0 to 332 seconds.
Next, we need to divide this change in concentration by the length of the time interval to get the average rate of change. The length of the time interval is the difference between the final and initial time: 332 s - 0 s = 332 s. So, the average rate of change of B is (-0.510 M) / (332 s) = -0.001536 M/s. This tells us that the concentration of B decreases by 0.001536 M per second on average over the given time interval.
As we know that the reaction is of form A -> 2B, the rate of formation of B is equal to twice the rate of A.
So, Rate of B = 2* Rate of A = 2*(-0.001536) = -0.003072 M/s

(d) If every unit that the Acme factory produces is sold for $4, write a function R(x) that gives the
cumulative revenue of the Acme factory where x is the number of days since the start of 2018.
Include the units of the function's output.
Answers
Revenue is calculated by multiplying the number of units sold by the price per unit. Multiply the output level by the price function to get the revenue function.
What is revenue function?R is expressed as a function of x. Remember that revenue = price quantity. Because we want the revenue to be a function of x, we must express the price and quantity in terms of x. The number is straightforward; it is x.If x is the number of units sold, we will refer to these two functions as: R(x) denotes the revenue function, while C(x) denotes the cost function. As a result, our profit function equation will be: P(x) = R(x) - C (x).Profit is a function. P(x) is the profit made from selling x units of the commodity and is represented by the difference.So here R(x) = 4(x)

Answers
Answer: The ratio between the units of measurement of nanometers and inches is 0.5 nm to 10 inches. This means that for every 0.5 nanometers, the equivalent measurement in inches is 10 inches.
We can use this ratio to find the conversion of other values from nanometers to inches as well.
We know that 1 nm = 20 inches, we can multiply the value 1 by 20 to get 20 inches
So 3 nm will be 3 * 20 = 60 inches
so, the value that can be placed in the ratio table where the question marks (?) are would be 1 nm = 20 inches

After 16 years in an account with a 5.9% annual interest rate compounded continuously, an investment is worth a total of $37,950.24. What is the value of the principal investment? Round the answer to the nearest penny. $14,765.24 $14,859.72 $23,185.00 $23,090.52
Answers
Answer: We can use the formula A = Pert to find the value of the principal investment P
Where A is the future value of the investment, r is the annual interest rate, t is the number of years, and e is the mathematical constant approximately equal to 2.718
In this case,
A = 37950.24, r = 0.059, t = 16
We can plug in the given values into the formula and solve for P:
37950.24 = P * e^(0.059 * 16)
To find the value of P we will divide both sides by e^(0.059 * 16)
P = 37950.24 / e^(0.059 * 16)
using the calculator to find the value of e^(0.059 * 16) gives 1.966862298
P = 37950.24 / 1.966862298
The value of P is $19,169.99.
Rounded to the nearest penny $19170
Therefore, the answer is $19,170.00
Step-by-step explanation:
A is the account value
P is the principal
r is the interest rate as a decimal
t is time
e is a standard/set value 2.7182818
Plug in what we know and then we are solving for the P value.
37950.24=P(2.718)^(.059 x 16)

Step-by-step explanation:
we can do even a little bit better than wild guessing and trying.
3x + 2y = 13

that means one term has to be odd and the other even, as only then their sum will be odd.
2y is because of the included factor 2 an even number. always.
so, 3x has to be odd.
and that means x has to be odd too. because an even number multiplied with any number is always even.
so, x can only be 1 or 3. because 3×5 = 15 (3×7 = 21, 3×9 = 27) and already too big for the sum 13.
so, for x = 1 we have
3×1 + 2y = 13
3 + 2y = 13
2y = 10
y = 5
for x = 3 we have
3×3 + 2y = 13
9 + 2y = 13
2y = 4
y = 2
