Use the distance formula of coordinate geometry.

Mark all the coordinates.

(-5, 5) , (-1, 7) , (4, -3) , (0, -5)

We need to find the length and width of the rectangle.

Lets pick, (4, -3) and (0, -5).

Distance formula,

√((x₁ - x₂)² + (y₁ - y₂)²)

or, √((4 + 0)² + (-3 + 5)² = √20 = 2√5 (width)

Again, we can take (-5, 5) and (0, -5)

√(25 + 100) = √125 = 5√5 (length)

Area of rectangle is length x width or 2√5 x 5√5 = 10 x 5 = 50 units²

Answer:

Hey there! To answer this question, we need to determine the rate at which the snow was falling, and then use that rate to calculate how much snow fell during school hours.

We know that 12 inches of snow fell in 26 hours, so the rate at which the snow was falling is 12 inches / 26 hours = 0.46 inches/hour.

If we want to find out how much snow fell during school hours, which is approximately 6 hours, we can use the following formula:

Snowfall during school hours = rate of snowfall * time

Plugging in the values, we get:

Snowfall during school hours = 0.46 inches/hour * 6 hours = 2.76 inches

So if 12 inches of snow fell in 26 hours at a rate of 0.46 inches/hour, we can estimate that approximately 2.76 inches of snow fell during school hours.

The probability that the student plays a sport and is involved in theatre is 82%*20%=16.4% which is approximately equal to 14%.

The probability that the student plays a sport and is involved in theatre can be calculated using the following formula:

P(A∩B)=P(A)*P(B|A)

Where P(A) is the probability of playing a sport (70%) and P(B|A) is the probability of being involved in theatre given that the student plays a sport (20%).

Therefore, P(A∩B)=0.7*0.2=0.14

This means that the probability that the student plays a sport and is involved in theatre is 14%. This can also be calculated by subtracting the probability of not playing a sport or being involved in theatre (18%) from 100%. That is, 100%-18%=82%. Since 20% of the 82% are involved in theatre, the probability that the student plays a sport and is involved in theatre is 82%*20%=16.4% which is approximately equal to 14%.

Answer:

6.45kg

Step-by-step explanation:

there are 1000g in one kilogram

250g/1000g=0.25kg

4.2kg+2.25kg=6.45kg

Answer:

6.45kg

Step-by-step explanation:

First, let us convert all the values into grams.

Weight of a watermelon ⇒ 4.2 kg

Multiply by 1000 to convert it to grams.

Weight of a watermelon ⇒ 4200 g

Weight of a pumpkin ⇒ 2kg 250g

First, multiply 2kg by 1000 to convert it to grams and add it to 250 grams.

Weight of a pumpkin

⇒ ( 2 × 1000 ) + 250

⇒ 2000 + 250

⇒ 2250 g

Total Weight  :

To get the total weight, add the weights of the watermelon and pumpkin in grams.

Total weight ⇒ 4200g + 2250g

                     ⇒ 6450g

Now to convert the answer into kilograms, divide the answer by 1000.

⇒ 6450/1000 = 6.45kg

V(t) = 30 * e^(-0.012t) is the value of the car after t years.

The value of the car 2 years from now will be approximately $29,300.

Let's call the original value of the car V0, and the decay factor k. The exponential model representing the value of the car after t years is given by:

V(t) = V0 * e^(-kt)

To find the value of the car after 3 years, we can plug in t=3 into the equation:

V(3) = V0 * e^(-k*3) = 18

We can rearrange the equation to solve for the decay factor k:

k = -ln(V(3)/V0)/3

Plugging in the known values, we get:

k = -ln(18/V0)/3

Since the value of the car has decreased by 40%, V0 = 18 / (1 - 0.4) = 30. Therefore, k = -ln(18/30)/3 = -0.012.

Therefore, the exponential model representing the value of the car after t years is:

V(t) = 30 * e^(-0.012t)

V(2) = 30 * e^(-0.012*2) = 30 * e^(-0.024) = 30 * 0.977 = 29.3

Here we have given that  a new xar 3 years ago. Its value has decreased exponentially by 40 percent since I got it and it's now worth $18,000

Here let us consider that the original value of the car E0, and the decay factor k.

Then the exponential model representing the value of the car after t years is written as

=> [tex]E(t) = E0 \times e^{-kt}[/tex]

Here we need to find the value of the car after 3 years, then we have to  plug in t=3 into the equation, then we get,

[tex]E(3) = E0 \times e^{-k\times3}= 18[/tex]

Now, we have to rearrange the equation to solve for the decay factor k, then we get the value as,

=> k = [-ln(E(3)/E0)]/3

Now, we have to put the values on the equation then we get

=> k = [-ln(18/V0)]/3

Here we know that the value of the car has decreased by 40%,

Therefore, it can be written as,

=> E0 = 18 / (1 - 0.4) = 30.

Therefore, the value of

=> k = -ln(18/30)/3 = -0.012.

Now the exponential model representing the value of the car after t years is calculated as

[tex]E(t) = 30 \times e^{-0.012t}[/tex]

Apply the value of t as 2, then we get the value of E(T) as,

The normal of a function is a line that is perpendicular to the tangent line at a particular point on the curve.

The normal of a function can be used to find the equation of the tangent line to the curve at a particular point. This is done by finding the slope of the normal and the coordinates of the point of tangency, and then using these values to write the equation of the line in slope-intercept form (y = mx + b).

For example, consider the curve y = x^2. If we want to find the equation of the tangent line to this curve at the point (2,4), we can take the derivative of y = x^2, which is y' = 2x. Setting x equal to 2, we find that the slope of the tangent line at (2,4) is 4.

The normal to this curve at (2,4) is perpendicular to the tangent line, so its slope is the negative reciprocal of the slope of the tangent line, or -1/4. We can then use the coordinates of the point of tangency (2,4) and the slope of the normal (-1/4) to find the equation of the normal: y - 4 = -1/4(x - 2), which simplifies to y = -x/4 + 2.

Answer:

The graph of the function y = sqrt(x + 1) - 2 is a transformation of the graph of the parent function y = sqrt(x). The parent function y = sqrt(x) is the square root function in its simplest form, with no transformation applied to it.

The transformation y = sqrt(x + 1) - 2 affects the parent function in the following ways:

The function inside the square root sign (x + 1) is shifted one unit to the right, meaning that the graph is shifted one unit to the right.

The function is then shifted two units downward, meaning that the graph is shifted two units downward.

As a result, the graph of y = sqrt(x + 1) - 2 is the same as the graph of y = sqrt(x), but shifted one unit to the right and two units downward.

Both of the functions has the same vertex point which is (-1,-2) and the domain is x>=-1 and the range is y>=-2.

It also shares the same shape as the parent function, an upward opening parabola with vertex at the origin.

The slope-intercept form of the equation is b = -0.0016a + 210 and the boiling point at 2300ft is 206.32°F

A linear function is an equation that describes a straight line when graphed. It has the form y = mx + b, where m is the slope of the line and b is the y-intercept. Linear functions are used to model relationships between two variables, such as the cost of a product and its quantity.

In this problem, we can model the boiling point in form of a linear equation.

The data given;

The slope can be calculated as;

m = y₂ - y₁ / x₂ - x₁

m = 202.8 - 197.04 / 4500 - 8100

m = -0.0016

Using this in the slope-intercept form of a linear function, we can find the y-intercept.

y = mx + c

Taking one point;

202.8 = -0.0016(4500) + c

c = 210

The linear equation can be written as

b = -0.0016a + 210

The following is one of the requirements for using a one-way, between-subjects Anova is the data must be measured on a continuous scale.

One of the requirements for using a one-way, between-subjects ANOVA is that the data must be measured on a continuous scale. This means that the variable being measured (such as time, weight, or temperature) should be able to take on any value within a certain range.

Another requirement for using a one-way, between-subjects ANOVA is that the data must be independent. This means that the observations for each group should not be related to one another in any way. For example, if the groups being compared are different treatment groups in a medical study, it would not be appropriate to use a one-way, between-subjects ANOVA if the patients in each group were related to one another (such as siblings or close friends).

The third requirement is that the data should be approximately normally distributed in each group. A normal distribution is a probability distribution that has a bell shape, which means that the data is symmetric and the mean, median, and mode are equal. The ANOVA assumes that the data is normally distributed and if the data is not normally distributed, the results may be unreliable. This requirement can be checked by using normality test such as Shapiro-Wilk test.
