What is product one word answer?

Answer:

Step-by-step explanation:

area of a circle formula is πr²

Find area of the larger and smaller circles and then subtract to find the shaded region. π = 3.14

area of the larger circle = π (11.5)²

                                      3.14 (132.25)

                                      415.265 units²

area of the smaller circle = π (5.5)²

                                           3.14(30.25)

                                           94.985 units²

subtract:   415.265 - 94.985 = 320.28 units²

240 square feet is the area of a square mural. The approximate length of one side of the mural is between 15 and 16 feet.

The area of a square is described as the number of square units needed to fill a square. In general, the area is described as the territory occupied inside the boundary of a flat object or 2d figure. The calculation of area is done in square units, with the standard unit being square metres (m²).

The area of the square = (side)²

240 = (side)²

side = √240

side = 4√15

side = 15.49 feet

Hence, The approximate length of one side of the mural is between 15 and 16 feet.

Therefore, the correct option is (4).

According to the question

Given that,

A quadratic equation x²+Kx-8=0 where one root is -4

If -4 is a root of the equation  x²+Kx-8=0 then if we put -4 in the pace of x we would get the final answer as 0 or in other words, -4 would satisfy the equation x²+Kx-8=0.

Hence,

⇒   x²+Kx-8=0.

⇒   (-4)²+ K(-4) - 8 = 0

Answer:

The Lawn Order lawnmower factory can produce 12 lawnmowers in 8 hours. This means that the factory's production rate is 12 lawnmowers per 8 hours. To find how many hours it will take the factory to produce 30 lawnmowers, we can use the formula:

Time = (quantity of work to be done) / (rate of work)

In this case:

Time = 30 lawnmowers / (12 lawnmowers per 8 hours)

To solve the equation we can multiply both sides by 8/12:

Time = (30 lawnmowers * 8 hours) / (12 lawnmowers)

The result is:

Time = 20 hours

So it will take the factory 20 hours to produce 30 lawnmowers.

Answer:

45 hours.

Step-by-step explanation:

The factory makes 12 lawnmowers in 8 hours. You would divide 12 by 8 to see how many they make in 1 hour. That would be 1.5 So, you multiply 1.5 by 30 to get 45.

If Marsha bought a new car for $21152.25 and picked cost is $2150 and sales tax is $1007.25 , then the base price of Marsha's car is $17995  .

the price that Marsha paid for the car is = $21152.25   ;

the picked cost for the car is = $2150  ;

the sales tax for the car is = $1007.25  ;

the formula to calculate the Marsha's car is = (Amount Paid) - (Picked Cost + Sales tax) ;

substituting the values ,

we get ;

Alvin's average paddling rate was 6.6 km/h.

We know that,

Speed= Distance/ Time  (solve for distance)

Distance = Speed × Time

To Campsite against the current,

Speed=r-y   ; speed=(r-3)

Time = 8 hours

Distance = (r-3)×8     (equation 1)

From Campsite with the current,

Speed = r + y   ; speed=(r+3)

Time = 3 hours

Distance = (r+3)×3        (equation 2)

Equating equation 1 and equation 2  because distance is same in both case,

(r+3)×3=(r-3)×8

3r+9=8r-24

So, the answer is $285,671.10 (Option b) that must be deposited earning 6.2% compounded yearly in order to make the annuity payment of $25,312 for 20 years.

The formula to determine the future value of an annuity is given by

FV = PV(1+r)^n + PMT( (1+r)^n - 1) / r

Where:

FV is the future value of the annuity

PV is the present value of the annuity

PMT is the payment made at the end of each period

r is the interest rate per period

n is the number of periods

We know that the payment made at the end of each period (PMT) is $25,312, the interest rate (r) is 6.2% and the number of periods (n) is 20.

We are looking for the present value of the annuity (PV)

So we can substitute the known values into the formula and solve for PV:

PV = PMT( (1+r)^n - 1) / (r (1+r)^n)

PV = $25,312 * ( (1+0.062)^20 - 1) / (0.062 (1+0.062)^20)

PV = $25,312 * (1.062^20 - 1) / (0.062 * 1.062^20)

PV = $25,312 * (1.062^20 - 1) / (0.062 * 1.062^20)

PV = $25,312 * (2.547 - 1) / (0.062 * 2.547)

PV = $25,312 * 1.547 / 0.157

PV = $285,671.10

Therefore, the answer is $285,671.10 (Option b) that must be deposited earning 6.2% compounded yearly in order to make the annuity payment of $25,312 for 20 years.

The derivative of logₐ x (log x with base a) is 1/(x ln a).

Here, the interesting thing is that we have "ln" in the derivative of "log x". Note that "ln" is called the natural logarithm (or) it is a logarithm with base "e". i.e., ln = logₑ.

Further, the derivative of log x is 1/(x ln 10) because the default base of log is 10 if there is no base written.

The derivative of log x (base 10) with respect to x is denoted by d/dx (log x) or (log x)'. Thus,

d/dx(logₐ x) (or) (logₐ x)' = 1/(x ln a)

d/dx(log x) (or) (log x)' = 1/(x ln 10)

d/dx (logₐ x) = 1 / (x ln a)

Substitute a = e on both sides. Then we get:

d/dx (loge x) = 1 / (x ln e)

By the properties of natural logarithms, ln e = 1. So

d/dx (loge x) = 1 / (x · 1)

Thus, d/dx (loge x) = 1.

Replacing loge x with ln x back, we get d/dx (ln x) = 1/x.

Hence, the derivatives of logs are:

d/dx (logₐ x) = 1 / (x ln a) (this is the derivative of common logarithm)

d/dx (ln x) = 1/x (this is the derivative of natural logarithm)
