The approximate area, of the baseball diamond is 8192 ft²

Step-by-step explanation:

The given coordinates of the baseball diamond are;

(0, 64), (64, 0), (0, -64), and (-64, 0)

The length of one unit of the coordinate plane = 1 foot

Therefore, we note that, there are two points with x-coordinate = 0 at which the y-coordinates = 64 and -64

Similarly here are two points with y-coordinate = 0 at which the x-coordinates = 64 and -64

The length of the segment are therefore the vertices of a square as we have;

A(0, 64), B(64, 0), C(0, -64), and D(-64, 0)

∠DBA = ∠DCA = tan⁻¹(64/64) = tan⁻¹(1) = 45°

∠DBA + ∠DCA = ∠ABC = 90°

The shape of the diamond is a square

The length, l of the side of the square is given by the relation;

[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

When, (x₁, y₁) = (0, 64), (x₂, y₂) = (64, 0)

We have;

[tex]l = \sqrt{\left (0 -64 \right )^{2}+\left (64-0 \right )^{2}} = 64\cdot \sqrt{2}[/tex]

The

The area, A, of the baseball diamond is therefore;

A = Area of a square = (Length of the side of a square)² = (64·√2)² = 8192 ft²

The area, of the baseball diamond = 8192 ft².

Answer:

Dimensions of the rug = 13 ft × 26 ft

Step-by-step explanation:

Dimensions of the room = 21 ft × 34 ft

Area of the room = 21 × 34 = 714 ft²

Cynthia wants to leave a uniform strip of floor around the rug.

Let the width of the rug = x ft

Then the dimensions of the rug will be = (21- 2x)ft × (34 - 2x)ft

Area of the rug = (21 - 2x)×(34 - 2x) square feet

338 = (21 - 2x)×(34 - 2x)

338 = 714 - 68x - 42x + 4x²

4x² - 110x + 714 - 338 = 0

4x² - 110x + 376 = 0

2x² - 55x + 188 = 0

2x² - 47x - 8x + 188 = 0

x(2x - 47) - 8(x - 47) = 0  

(x - 4)(2x - 47) = 0

x = 4, [tex]\frac{47}{2}[/tex]

For x = 23.5 area of the rug will be negative.

Therefore, x = 4 ft will be the width of the rug.

Dimensions of the rug will be 13 ft × 26 ft.

Answer:

Actual distance between the 2 priers = 90 MI

Step-by-step explanation:

Ratio of Scaled drawing to actual dimension = 2 : 15

2 cm represents 15MI

2cm ≡ 15 MI

∴ 1 cm ≡ (15/2) MI

1 cm ≡ 7.5 MI

scaled distance of priers in drawing = 12cm

∴ 12 cm ≡ 7.5 × 12

= 90 MI

∴ Actual distance between the 2 priers = 90 MI

Answer:

It took 11.04 hours  by Stephanie.

Step-by-step explanation:

Concept

distance = speed*time

time = distance/time

_________________________________

Given

for Steven

time  = 10 hours

speed = 53 miles per hour

Distance for steven = 53*10 = 530 miles

_____________________________________

Now ,

as Stephanie also traveled the same distance as steven

Distance = 530 miles

speed = 48 miles per hour

time = 530/48 hour = 11.04 hours

Thus, It took 11.04 hours  by Stephanie.

In other way

since distance traveled by Steven and Stephanie are same

let time taken by Stephanie be x hours

Distance traveled by steven = Distance traveled by Stephanie

53*10 = 48*x

x = 530/48 = 11.04 hours

equation = 53*10 = 48*x

Answer:

274

Step-by-step explanation:

First stop of Caroline = At 36 mile marker

Destination of Caroline = At 353 mile marker

Distance left to be covered = 353 - 36 = 317 miles

Given that Caroline decides to stop at an attraction [tex]\frac{3}{4}[/tex] of the way after she stops for gas.

i.e. at a distance [tex]\frac{3}{4}[/tex] of 317 miles away from the Gas stop.

[tex]\frac{3}{4} \times 317 = 79.25\times 3 \approx 238\ miles[/tex]

So, Caroline stops at a point which is around 238 miles away from the gas station.

To calculate the Mile marker of her stop, we need to add the mile marker of gas station and the distance of her stop from gas station.

Mile marker location at her stop = 36+238 = 274

Answer:

slope: (y₂ - y₁) / (x₂ - x₁)

(5 - 2) / (-1 - 1) = 3/-2 = -3/2

y = -3/2x + b

5 = -3/2(-1) + b

5 = 3/2 + b

b = 3.5

y = -3/2x - 7/2

(5.83 - 1.42) / (4.22 + 0.72) = 4.41/4.94

y = 4.41/4.94x + b

5.83 = (4.41/4.94)(4.22) + b

5.83 = 3.76724696 + b

b = 2.06275304

y = 4.41/4.94x + 2.06

(the numbers are really wacky so i hope thats right, so sorry if it isn't)

Answer:

See below.

Step-by-step explanation:

So we have the graph of:

[tex]x^2+y^2=8[/tex]

As given, the graph is a circle with a radius of 2√2 and a center of (0,0)

Part 1)

The domain of a function is the span of x-values it covers and the range of a function is the span of y-values it covers.

From the graph, we can see that the x-values the graph covers goes from -2√2  to +2√2. The graph includes these values.

Thus, the domain is, in interval notation:

[tex][-2\sqrt2,2\sqrt2][/tex]

From the graph, we can see that the y-values the graph covers also goes from -2√2 to 2√2.

Therefore, like the domain, the range in interval notation is:

[tex][-2\sqrt2,2\sqrt2][/tex]

Part 2:

First of all, we can use the vertical line test to prove that the graph is indeed not a function.

Algebraically, we have to do some more.

First, recall what it means when an equation is not a function. It means that one x maps onto two or more ys.

In other words, to prove that the equation is not a function, we can substitute an x for a value and solve for y.

For instance, let's use 0 for x (and 0 is within the domain). Thus:

[tex]x^2+y^2=8\\(0)^2+y^2=8[/tex]

Simplify:

[tex]y^2=8[/tex]

Take the square root of both sides:

[tex]y=\pm\sqrt8\\y=\pm2\sqrt2[/tex]

In other words, when x is 0, y can be either -2√2 or 2√2. So we have two different y-values with the same x-coordinate.

[tex](0,-2\sqrt2)(0,2\sqrt2)[/tex]

Therefore, the equation is not a function.

Answer:

x < 6

Step-by-step explanation:

Given

- 3x + 51 > 13 + 7x - 22 ( simplify right side )

- 3x + 51 > 7x - 9 ( subtract 7x from both sides )

- 10x + 51 > - 9 ( subtract 51 from both sides )

- 10x > - 60

Divide both sides by - 10, reversing the symbol as a result of dividing by a negative quantity.

x < 6

Answer:

[tex]\Large \boxed{a=\frac{-1}{4} }[/tex]

Step-by-step explanation:

[tex]\displaystyle \frac{3}{a} \cdot x - 4 = 20[/tex]

Let x = -2.

[tex]\displaystyle \frac{3}{a} \cdot (-2) - 4 = 20[/tex]

Solving for a.

[tex]\displaystyle \frac{-6}{a}- 4 = 20[/tex]

Adding 4 to both sides.

[tex]\displaystyle \frac{-6}{a} = 24[/tex]

Multiplying both sides by a, then dividing both sides by 24.

[tex]\displaystyle \frac{-6}{24} = a[/tex]

Simplifying.

[tex]\displaystyle \frac{-1}{4} = a[/tex]

Answer:

Answer:

-7 is in our domain.

0 is in our domain

7 is not in our domain.

Step-by-step explanation:

So we have the rational function:

[tex]f(x)=\frac{x}{x-7}[/tex]

The domain restrictions of rational functions are the zeros of the denominator.  In other words, the domain of rational functions are always all real numbers except for the zeros of the denominator.

So, solve for the denominator by setting it to 0:

[tex]x-7=0[/tex]

Add 7 to both sides:

[tex]x=7[/tex]

So, our domain is all real numbers except for 7.

(When x=7, we have 7/0, which is undefined.)

Therefore:

-7 is in our domain.

0 is in our domain

7 is not in our domain.

Step-by-step explanation:

The amount of profit Rodney made when he sold 200 bags of popcorn is given by A = $ 100

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the equation is

Let the amount for renting the machine be = $ 70

The amount per bag for packing popcorn = $ 0.15 per bag

The sale price of the popcorn per bag = $ 1.00

And ,

The total number of bags sold by Rodney = 200 bags

So , the total profit made by Rodney A is calculated from the equation ,

Total amount made by Rodney = total number of bags sold by Rodney x sale price of the popcorn per bag

Substituting the values in the equation , we get

Total amount made by Rodney = 200 x 1

Total amount made by Rodney = $ 200

Now , the cost per bag is deducted from the total amount made by Rodney

So ,

Total amount made by Rodney after deduction of bag cost = ( Total amount made by Rodney - amount per bag for packing popcorn x 200 )

Substituting the values in the equation , we get

Total amount made by Rodney after deduction of bag cost =

= 200 - ( 0.15 x 200 )

= 200 - 30

= $ 170

Now , the cost of renting the machine should also be deducted from the remaining amount to calculate the profit earned by Rodney

So , The profit earned by Rodney A = 170 - amount for renting the machine

The profit earned by Rodney A = $ 170 - $ 70

The profit earned by Rodney A = $ 100

Therefore , the value of A is $ 100

Hence , The amount of profit Rodney made when he sold 200 bags of popcorn is given by A = $ 100
