The approximate cost per square foot for the tiles is $3.22 when rounded to the nearest cent.

To calculate the price per square foot of tiles, divide the total cost of the tiles by the total number of square feet. The total cost given is $40.21, and the total area is 12 1/2 square feet.

First, convert the mixed number to an improper fraction. 12 1/2 is the same as 25/2 square feet. Now, to find the cost per square foot, perform the following division:

Price per square foot = Total cost / Total area in square feet

Price per square foot = $40.21 / (25/2 square feet)

Multiply by the reciprocal:

Price per square foot = $40.21 / 1 x 2 / 25

Price per square foot = $40.21 x 2 / 25

Price per square foot = $80.42 / 25

Price per square foot = $3.2168

Therefore, the approximate cost per square foot for the tiles is $3.22 when rounded to the nearest cent.

The approximate price per square foot is $3.22.

To find the price per square foot, divide the total cost by the total square footage. In this case, the cost is $40.21 and the square footage is 12 1/2 square feet.

1. Cost per square foot = Total cost / Total square footage

2. Cost per square foot = $40.21 / 12.5 sq ft ≈ $3.22/sq ft

1. Convert 12 1/2 square feet to a decimal: 12.5 sq ft.

2. Divide the total cost by the total square footage: $40.21 / 12.5 sq ft ≈ $3.22/sq ft.

To calculate the cost per square foot, you need to divide the total cost by the total square footage. In this case, the total cost is $40.21, and the total square footage is 12 1/2 square feet.

Answer:

Option 1 is correct.

Step-by-step explanation:

The given polynomial is

[tex]f(x)=20x^4+x^3+8x^2+x-12[/tex]

we have to find  all the rational roots of the polynomial f(x)

The Rational Root Theorem states that the all possible roots of a polynomial are in the form of a rational number i.e in the form of [tex]\frac{p}{q}[/tex]

where p is a factor of constant term and q is the factor of coefficient of leading term.

In the given polynomial the constant is -12 and the leading coefficient is 20.

[tex]\text{All possible factor of -12 are }\pm1,\pm2, \pm3, \pm4,\pm6,\pm12[/tex]

[tex]\text{All possible factor of 20 are }\pm1,\pm2,\pm4,\pm5,\pm10,\pm20[/tex]

So, the all possible rational roots of the given polynomial are,

[tex]\pm1,\pm2, \pm3, \pm4,\pm6,\pm12,\pm\frac{1}{2},\pm\frac{3}{2},\pm\frac{1}{4},\pm\frac{3}{4},\pm\frac{1}{10},\pm\frac{1}{5},\pm\frac{3}{5},\pm\frac{3}{10},\pm\frac{2}{5},\pm\frac{6}{5},\pm\frac{1}{20},\pm\frac{3}{20},\pm\frac{4}{5},\pm\frac{12}{5}[/tex]

Now, the rational roots of polynomial satisfy the given polynomial

[tex]f(-\frac{4}{5})=20(-\frac{4}{5})^4+(-\frac{4}{5})^3+8(-\frac{4}{5})^2-\frac{4}{5}-12=\frac{256}{625}\times 20-\frac{64}{125}+\frac{128}{125}-\frac{4}{5}-12[/tex]

[tex]=\frac{1024}{125}-\frac{64}{125}+\frac{128}{25}-\frac{4}{5}-12[/tex]

[tex]=\frac{960}{125}+\frac{128}{25}-\frac{4}{5}-12=12-12=0[/tex]

Hence, rational root.

[tex]f(\frac{3}{4})=20(\frac{3}{4})^4+(\frac{3}{4})^3+8(\frac{3}{4})^2+\frac{3}{4}-12=\frac{405}{64}+\frac{27}{64}+\frac{9}{2}+\frac{3}{4}-12=0[/tex]

rational root

[tex]f(1)=20(1)^4+(1)^3+8(1)^2+1-12=20+1+8-11=18\neq 0[/tex]

not a rational root.

hence, option 1 is correct

Answer:

T = 13.9 + 12.85 + 14.82 + 12.74

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Based on the information in the question, the total time for the relay would be calculated by simply adding each of the four-relay members time during the 100 meter run. Therefore the expression would be

T = 13.9 + 12.85 + 14.82 + 12.74

T = 54.31 seconds.

If we decided to solve for the Total time (T) it would add up to 54.31 seconds for the relay time. But since the question did not ask for the total but just the expression. Then the answer is the expression above.

Answer:

Te plant was 228.29 centimeters tall.

Step-by-step explanation:

To find the size of the plant 14 days (2 weeks ago), we will use a formula called "exponential growth."

[tex]A=P(1+r)^{t}[/tex]

where

A=accumulated amount.

P=initial ammount

r=rate

t=elapsed time.

replacing the values ​​we have

A=452 centimeters

P=variable to find

r=5% = 0.05

t=2 weeks= 14 days

So, we substitute the values ​​in the equation

[tex]452=P(1+0.05)^{14}[/tex]

Then, we clear the variable P

[tex]P=\frac{452}{1.05^{14} }[/tex]

and perform the operations

[tex]P=\frac{452}{1.979931} =228.29centimeters[/tex]

The double integral of the function f(x, y) = x over the rectangle defined by [1, 6] and [4, 5] is calculated through an iterated integral to be 17.5.

The problem asks to find double integral of the function f(x, y) = x over the rectangle R defined by the interval [1, 6] for x and [4, 5] for y. To find this, we perform an iterated integral. The integral is setup as follows:

∬Rf(x,y)dA = ∫ from 1 to 6 ∫ from 4 to 5 x dy dx

We first integrate with respect to y which gives us: xy| from 4 to 5 = x(5) - x(4) = x.

Then, we integrate this result with respect to x which gives us: 0.5x²| from 1 to 6 = 0.5(6^2) - 0.5(1^2) = 17.5

So, ∬Rf(x,y)dA equals to 17.5

Answer:

Step-by-step explanation:

In this exercise we have to perform the parameterization of the given function and we will have:

[tex]\int\limits_C {f} \, dr = f(1, 2)-f(-1, 2)= 2/3[/tex]

In there is some scalar function [tex]f(x, y)[/tex] such that:

[tex]\nabla f(x,y) = f(x, y) = x^2i+y^2j[/tex]

Then we want to find [tex]f[/tex] such that:

[tex]f'(x)= x^2= f(x,y) = \frac{x^3}{3} + g(y)\\f'(y)= y^2= f(x,y)= \frac{y^3}{3} + C\\f(x, y)= \frac{x^3}{3} +\frac{y^3}{3} + C[/tex]

So the vector filed [tex]f(x, y)[/tex] is conservative, which means the fundamental theorem applies; the line integral of [tex]f[/tex] along any path [tex]C[/tex] parameterized by some vector-valued function [tex]r(t)[/tex] over [tex]a\leq t\leq b[/tex] is given by:

[tex]\int\limits_C {f} \, dr\\\int\limits^t=a_t=b {f(r(t))} \, dt= f(r(b))-f(r(a))[/tex]

In the case:

[tex]\int\limits_C {f} \, dr = f(1, 2)-f(-1, 2)= 2/3[/tex]

The decimal 0.8333 is equivalent to the fraction 2/3.

To convert the decimal 0.8333 to a fraction, follow these steps:

Step 1: Let x be the decimal value:

x = 0.8333

Step 2: Multiply both sides of the equation by 10000 to remove the decimal:

10000x = 8333.3

Step 3: Subtract x from both sides of the equation:

10000x - x = 8333.3 - 0.8333

9999x = 8332.4667

Step 4: Divide both sides of the equation by 9999 to isolate x:

x = 8332.4667 / 9999

Divide both the numerator and the denominator by their greatest common divisor, which is 3333:

x = (8332.4667 ÷ 3333) / (9999 ÷ 3333)

x = (2.49995) / 3

Now, the fraction as a whole number over the denominator:

x = 2 / 3

The car can drive 216 miles on 12 gallons.

The rate of change of position is called as displacement.

Now it is given that,

Distance traveled by car = 630 miles

Gas required to travel 630 miles = 35 gallons

Therefore, Distance travel n 1 gallon = Distance traveled by car / Gas required to travel 630 miles

⇒ Distance travel n 1 gallon = 630 / 35 miles

⇒ Distance travel n 1 gallon = 18 miles

Therefore, Distance travel n 12 gallon = 12 * Distance travel n 1 gallon

⇒ Distance travel n 12 gallon = 12 * 18 miles

⇒ Distance travel n 12 gallon = 216 miles.

Thus, the car can drive 216 miles on 12 gallons.

The only value of x where f(x) = 0 can be determined by looking at the function's behavior near the x-axis and using the Intermediate Value Theorem. In this case, the potential x value is -9.

The one and only value of x where f(x) = 0 is the point of the function that intersects the x-axis. Since the function is continuous, it must cross the x-axis at this point due to the Intermediate Value Theorem.

To determine the possible value of x, we look at the given function values at x = -10 and x = -8 and identify where the function changes sign from negative to positive. The value of x where this sign change happens is the possible x value.

From the provided choices, the only value that would make this sign change possible is -9. Therefore, -9 could be the value of x where f(x) = 0.

Carlene needs to sell 400 more T-shirts at $20.50 each to reach her goal of raising more than $8,900, after already raising $700.

The question asks us to determine how many more T-shirts, designated as x, Carlene needs to sell to reach her fundraising goal of more than $8,900, given that each T-shirt costs $20.50 and she has already raised $700. To solve for x, we can set up the following equation:

Total goal - Amount already raised = Amount still needed

$8,900 - $700 = $8,200

Next, we divide the amount still needed by the price per T-shirt to find out how many T-shirts need to be sold:

x = Amount still needed / Price per T-shirt

x = $8,200 / $20.50

x = 400
