Answer:

If its written as the fourth root of (81^3) the answer is 27.

Answer:

First one

Step-by-step explanation:

Answer:

A) Irrational

Step-by-step explanation:

The square root of 27 is an irrational number since it's not a rational number. We identify rational numbers because they can be expressed as fractions

If we take the value of [tex]\sqrt{27}[/tex] we get

5.1961524227066318805823390245176...

There is no way to transform that number into a fraction because

* It has no decimal limit

* It has no decimal pattern (or period)

Examples of rationals are

5.44444...

[tex]0.\overline{32}[/tex]

2.375

The last one has limited decimals, the first two have repetitive patterns or a period.

Which situation can be modeled by the inequality [tex]65-8x\ge 9?[/tex]

Suppose you have $65.

Each day you spend $8.

You want to have at least $9 left.

If x is the number of days you are spending money, what is the maximum number of days you can spend money?

Solution:

Let x be the number of days you are spending money, each day you spend $8, so in x days you spend $8x. Initially, you have $65, so after x days, $(65 - 8x). This amount of money must be no less than $9, so

The statement H(30) = H(25) + 5 means that when Amelia was 30 months old, she was 5 centimeters taller than when she was 25 months old.

The function H(t) tells us Amelia's height in centimeters when she was t months old. So H(30) tells us Amelia's height when she was 30 months old, and H(25) tells us Amelia's height when she was 25 months old.

The equation H(30) = H(25) + 5 tells us that these two values are equal, which means that Amelia was 5 centimeters taller when she was 30 months old than when she was 25 months old.

Answer:

The manufacturer should decrease the level of unskilled labor by 2 for the total output to stay the same.

Step-by-step explanation:

Q(x,y) = 60 x^⅓ y^⅔

Take the partial derivatives with respect to x and y.

∂Q/∂x = 20 x^-⅔ y^⅔

∂Q/∂y = 40 x^⅓ y^-⅓

So the total differential is:

dQ = ∂Q/∂x dx + ∂Q/∂y dy

dQ = 20 x^-⅔ y^⅔ dx + 40 x^⅓ y^-⅓ dy

If dQ = 0:

0 = 20 x^-⅔ y^⅔ dx + 40 x^⅓ y^-⅓ dy

If x = 10, y = 40, and dx = 1:

0 = 20 (10)^-⅔ (40)^⅔ (1) + 40 (10)^⅓ (40)^-⅓ dy

0 = 20 (4)^⅔ + 40 (1/4)^⅓ dy

-20 (4)^⅔ = 40 (1/4)^⅓ dy

-20 (4)^⅔ (1/4)^⅔ = 40 (1/4)^⅓ (1/4)^⅔ dy

-20 = 40 (1/4) dy

-20 = 10 dy

dy = -2

The manufacturer should decrease the level of unskilled labor by 2 for the total output to stay the same.

To maintain the same level of production when adding one skilled worker, we use calculus to find the necessary change in the number of unskilled workers based on the manufacturer's production function.

The question deals with partial derivatives and their application in the context of production functions. Using calculus, specifically the concept of partial derivatives, we can estimate the change in the number of unskilled workers required to maintain the same level of production when there is an increase in the number of skilled workers. Given the manufacturer's production function Q(x, y) = 60x1/3y2/3, where x is the number of skilled workers and y is the number of unskilled workers, we first calculate the partial derivative of Q with respect to x, Qx, and then find the partial derivative with respect to y, Qy. We then use these derivatives to form an equation that represents the change in y needed to offset the change in x. With x initially at 10 and increasing by 1, and y initially at 40, we can solve for the change in y that keeps the total output constant.

Answer:

The actual speed of the car is either 57 mph or 63 mph

Step-by-step explanation:

Given as :

The measured speed o the car = 60 mph

The percentage error in speedometer = 5 %

Let The actual speed of car = x mph

Now, percentage error = [tex]\dfrac{\textrm actual value - \textrm measured value}{\textrm measured value}[/tex] × 100

So, [tex]\frac{5}{100}[/tex] = [tex]\frac{x - 60}{60}[/tex]

or,  [tex]\frac{5}{100}[/tex] × 60 = x - 60

Or, 3 = x - 60

∴  x = 63 mph

Hence The actual speed of the car is either 57 mph or 63 mph . Answer

The correct statement describing the actual speed of the car is: The actual speed of the car is either 57 mph or 63 mph.

To understand why this is the correct answer, let's calculate the range of possible actual speeds given the percent error of the speedometer.

The speedometer shows a speed of 60 mph with a percent error of 5%. The percent error formula is given by:

[tex]\[ \text{Percent Error} = \left( \frac{\text{Error}}{\text{True Value}} \right) \times 100\% \][/tex]

Here, the true value is the actual speed of the car, and the error is the difference between the measured speed (60 mph) and the true value. We can rearrange the formula to solve for the true value:

[tex]\[ \text{True Value} = \frac{\text{Measured Value}}{1 \pm \text{Percent Error}} \][/tex]

Since the percent error is 5%, we have:

[tex]\[ \text{True Value} = \frac{60 \text{ mph}}{1 \pm 0.05} \][/tex]

Now, we calculate the true value for both the lower and upper bounds of the speedometer reading:

For the lower bound (actual speed could be less than the measured speed):

[tex]\[ \text{True Value}_{\text{lower}} = \frac{60 \text{ mph}}{1 + 0.05} = \frac{60 \text{ mph}}{1.05} \approx 57.14 \text{ mph} \][/tex]

For the upper bound (actual speed could be more than the measured speed):

[tex]\[ \text{True Value}_{\text{upper}} = \frac{60 \text{ mph}}{1 - 0.05} = \frac{60 \text{ mph}}{0.95} \approx 63.16 \text{ mph} \][/tex]

Rounding these values to the nearest whole number, we get:

[tex]\[ \text{True Value}_{\text{lower}} \approx 57 \text{ mph} \][/tex]

[tex]\[ \text{True Value}_{\text{upper}} \approx 63 \text{ mph} \][/tex]

Therefore, the actual speed of the car could be either 57 mph or 63 mph, which corresponds to the third option provided in the question.

b=24

(b/2)^2=(24/2)^2=12^2=144

Answer:

Option C: 0.04 is the correct answer.

Step-by-step explanation:

Given that:

cups of sugar used = 7.5

cookies = 14 dozen

As we know that 1 dozen cookies equal 12 cookies so,

14 dozen cookies = 14* 12 = 168 cookies

Now,

we have to find the rate of cups of sugar per cookie, So:

Rate = cups of sugar / total cookies

By putting values:

Rate = 7.5/ 168

By simplifying we get

Rate = 0.04464

By rounding it off to nearest hundred:

Rate = 0.04

Hence the rate of cups of sugar per cookie is 0.04

Final answer:

The equation of the line with a slope of 2 that passes through the point (7,9) in slope-intercept form is y = 2x - 5, where 2 is the slope and -5 is the y-intercept.

Explanation:

To find the equation of a line with a slope of 2 that passes through the point (7,9), we can use the point-slope form of a line equation, which is:

[tex]y - y_1 = m(x - x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is the point the line passes through. Plugging in our values we get: y - 9 = 2(x - 7).

To convert this to slope-intercept form (y = mx + b), expand the right side to get y - 9 = 2x - 14 and then add 9 to both sides to isolate y, resulting in y = 2x - 5. Here, the m value is 2 (the slope) and the b value is -5 (the y-intercept).

Answer:

Part a) [tex]-16t^{2}+35t+1.5=0[/tex]

Part b)

[tex]a=-16\\b=35\\c=1.5[/tex]

Part c) The soccer ball will take 2.23 seconds to reach the ground

Step-by-step explanation:

we have

[tex]h(t)=-16t^{2}+35t+1.5[/tex]

where

t  is the time the ball has been in the air, in seconds

h(t) is the height, in feet, of the  soccer ball

Part a) Write an equation that could be used to determine the time the ball traveled before it hit the ground

we know that

When the ball hit the ground, the value of h(t) is equal to zero

so

For h(t)=0

[tex]-16t^{2}+35t+1.5=0[/tex]

This equation can be used to determine the time the ball traveled before it hit the ground

Part b) Determine the values of a, b, and c

we know that

The formula to solve a quadratic equation of the form

[tex]ax^{2} +bx+c=0[/tex]

is equal to

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]-16t^{2}+35t+1.5=0[/tex]

so

[tex]a=-16\\b=35\\c=1.5[/tex]

Part c)  How long will it take for the soccer ball to reach the ground after it was kicked?

Solve the quadratic equation by the formula

[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]

we have

[tex]a=-16\\b=35\\c=1.5[/tex]

substitute the values

[tex]x=\frac{-35(+/-)\sqrt{35^{2}-4(-16)(1.5)}} {2(-16)}[/tex]

[tex]x=\frac{-35(+/-)\sqrt{1,321}} {-32}[/tex]

[tex]x_1=\frac{-35(+)\sqrt{1,321}} {-32}=-0.04[/tex]  ---> cannot be a solution (is negative)

[tex]x_2=\frac{-35(-)\sqrt{1,321}} {-32}=2.23[/tex]

therefore

The soccer ball will take 2.23 seconds to reach the ground

The correct answer is D. 15 squared centimeters.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Base one = 10 centimeters

Base two = 5 centimeters

Height = 2 centimeters

2. Let's find out the area of the trapezoid, using the following formula:

Area = 1/2 (Base one + Base two) * Height

Replacing with real values:

Area = 1/2 (10 + 5) * 2

Area = 1/2 (15 * 2) = 1/2 (30)

Area = 15 centimeters ²

The correct answer is D. 15 squared centimeters.

The value of x is 6 and The value of y is - 4

Step-by-step explanation:

Given as :

The Two linear equation is

- 3 x - 9 y = 18

4 x + 3 y = 12

Now,

4 × ( - 3 x - 9 y ) = 4 × 18

Or, - 12 x - 36 y = 72      ......1

And 3 × ( 4 x + 3 y ) =  3 × 12

or, 12 x + 9 y = 36        .....2

Solving eq 1 and 2

( 12 x + 9 y ) + (  - 12 x - 36 y ) = 72 + 36

Or, 9 y - 36 y = 108

or , 27 y = - 108

∴ y = - [tex]\frac{108}{27}[/tex]

I.e y = - 4

Put the value of y to get x value

So, 12 x + 9 (-4) = 36

Or, 12 x = 36 + 36

or, 12 x = 72

∴  x = [tex]\frac{72}{12}[/tex]
