The correct option is d) 7.

A production function indicates the proportion of a combination of inputs (labor and capital) that produces a given amount of output. Firms determine the quantity produced given the output price level and the quantity of a combination of input factors provided by the prices of capital and labor. Dividing the output by the number of capital and labor units employed gives the average capital and labor production, respectively.

The production functions,

Q = 3 K + 4 L

k = 10

L = 10

Q = 3 ( 10 ) + 4 ( 10 )

Q = 30 + 40

Q = 70

Average capital production is calculated by dividing output (Q) by the amount of capital used to produce that output (K).

Average capital production = output / capital

= 70 / 10

= 7

Substituting these values into the formula for the discriminant, we get ...

  d = 4² -4(4)(1) = 16 -16 = 0

The discriminant of the polynomial is 0.

In the equation y = 2x + 3, the value of y when we substitute -3 for x is -3.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".

To evaluate an equation means to substitute a value to the variable and perform the arithmetic operations included.

Given the equation y = 2x + 3, if we substitute -3 for x, the equation becomes

y = 2(-3) + 3

Performing the arithmetic operations, we can have the value of y.

y = 2(-3) + 3

y = -6 + 3

y = -3

Hence, for the equation y = 2x + 3, y is -3 when x is -3.

The amount of money Savannah will have after 10 days is $0.35

Amount Savannah started with = 5 pennies

= $0.01 × 5

= $0.05

Additional amount per day = 3 pennies

= $0.01 × 3

= $0.03

Total savings in 10 days = 0.05 + 0.03(10)

= 0.05 + 0.3

= $0.35

Number of days it will take for her to have at least $1.50 = 0.05 + 0.03d

1.50 - 0.05 = 0.03d

1.45 = 0.03d

The true about the sum of the two polynomials- 6s^2t – 2st^2 and 4s^2t – 3st^2 is The sum is a binomial with a degree of 3.

A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.

Now the given polynomials are,

6s^2t – 2st^2 and 4s^2t – 3st^2

Now adding these two polynomials we get,

Sum of polynomials = 6s^2t – 2st^2 + 4s^2t – 3st^2

Taking alike terms together,

= 6s^2t + 4s^2t – 2st^2 – 3st^2

Now simplifying we get,

= 10s^2t – 5st^2

Here we see that the highest power of a variable is 2.

Thus this sum of polynomials is a binomial.

Now sum of the powers of variable s and t = 2 + 1 = 3

Thus, Degree of the sum of polynomials is 3.

Thus, the true about the sum of the two polynomials- 6s^2t – 2st^2 and 4s^2t – 3st^2 is The sum is a binomial with a degree of 3.

Given that Jupiter takes 9.9259 hours to rotate on its axis and has a tangential speed of 12,293 m/s, then its radius is 69,912 km.

Tangential speed is defined as the measure of the circumference of the circular path the object is moving along divided by the value of the amount of time it took to complete one rotation.

tangential speed = C/t

where C = circumference

t = time it took to complete one rotation

Given that Jupiter takes 9.9259 hours to rotate on its axis and has a tangential speed of 12,293 m/s, solve for the circumference of Jupiter.

C = tangential speed x time

C = 12,293 m/s (9.9259 hours)(3600s/hr)

C = 439,268,719.3 m

Using the formula for circumference, solve for the radius of Jupiter.

C = 2πr

r = C / 2π

r = 439,268,719.3 m/2π

A percentage in mathematics is a number or ratio that can be expressed as a fraction of 100.

The percent of the given number 26 % of 500 is 130.

A percentage in mathematics is a number or ratio that can be expressed as a fraction of 100. The term percent comes from the Latin "per centum" which means per hundred. The symbol percentage is used to represent percentage.

Let the equation be 26 % of 500

Percentage = (value/total value) × 100 %.

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

26 % of 500 = 26/100 of 500

26/100 × 500 = 130

Answer:

-(8/-4)² + 2 - 4³ = -66

Step-by-step explanation:

-(8/-4)² + 2 - 4³

Here we need to respect the order of operations.

So ,first we calculate what’s between parentheses :

8/-4 = -2

Then

-(8/-4)² + 2 - 4³ = -(-2)² + 2 - 4³

Then

We calculate the exponent :

(-2)² = (-2) × (-2) = 4

4³ = 4 × 4 × 4 = 64

Then

-(8/-4)² + 2 - 4³ = -4 + 2 - 64

Then

The expression -4 + 2 - 64 contains addition and subtraction.

So ,we start calculating from left to right :

-4 + 2 = -2

Then

-4 + 2 - 64 = -2 - 64 = -66

Conclusion :

-(8/-4)² + 2 - 4³ = -66
