Two objects are moving along separate linear paths where each path is described by position, d, and time, t. The variable d is measured in meters, and the variable t is measured in seconds. The equation describing the graph of the position of the first object with respect to time is d = 2. 5t 2. 2. The graph of the position of the second object is a parallel line passing through (t = 0, d = 1). What is the equation of the second graph? A. D = 2. 5t 1 B. D = t 2. 5 C. D = -0. 4t 1 D.

Answer:

3 people

$9.5 left over

Step-by-step explanation:

pp = 18 + 22.75

pp = 40.75

total people who can go = 131.75/pp

tp = 131.75/pp

tp = 3 remainder $9.5

(this is if they all arrive in individual cars)

The number of people that can go to the amusement park are 5 .

First, we need to find the amount left after deducting parking charges. Then the remaining amount can be divided by the price of one ticket to find out how many persons can buy the ticket from the same amount.

Thus, 5 number of persons can go to the amusement park.

The approximate surface area of this right triangular prism is 193.2cm

The surface area of a triangular prism is expressed as:

Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area)

Perimeter of the base = 6 + 6 + 6

Perimeter of the base = 18cm

Length of the prism = 9cm

Base area = 1/2 * 5.2 * 6
Base area  = 15.6cm

Determine the surface area

Surface area = (18 * 9) + 2(15.6)

Surface area = 162 + 31.2

Surface area = 193.2 cm

Hence the approximate surface area of this right triangular prism is 193.2cm

Answer:

This equation cannot be solved to find the correct width of the rectangle because the formula for the area of a rectangle is area = base times the height. Therefore, you can't just simply subtract 9 from 48 to get the width. Instead, you have to divide 48 by 9 to find the width, since 48 is the area and 9 is the length.

Additional comment

Changing the sign of the x-coordinate moves a point horizontally to the other side of the y-axis, reflecting it over the y-axis.

Multiplying coordinate values by the same factor effects a dilation about the origin by that factor.

Adding to the x-coordinate moves the point to the right; adding to the y-coordinate moves the point up. (Subtracting from x moves the point left.)

The value of c for a standard normal distribution, P(z < c) = 0. 3387 is -0.41.

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = (x - μ)/σ

Where x is the raw score, μ is the mean and σ is the standard deviation.

Given that P(z < c) = 0. 3387; hence:

From the normal distribution table, c = -0.41

The value of c for a standard normal distribution, P(z < c) = 0. 3387 is -0.41.

Step-by-step explanation:

In first bag there is 15 M&M's ANd second bag has a total of 9 M&M's so that means there are a total of 24 M&M's.

In the first bag there is 5 blue M&M's and in the second bag there is a total of 2 blue M&M's so there is a total of 7 blue M&M's all together.

so there are 7/24 M&M's ( what were going to do it convert it into percents.

To do this were going to use these steps.

Calculations

7 divided by 24=0.291666.

Ok so now what is 0.291666 x 100=?

0.291666 x 100=29.6667 and there is our final answer.

Answer:

The first, third, andd sixth choice is correct.

Step-by-step explanation:

The y-intercept is when x = 0.

So if we plug x = 0 into the equation.

y = -4(0) + 98

y = 98

So the first choice is correct.

y = mx + b

y = -4x + 98

m = slope

b = y-intercept

So, the slope must mean it's decreasing.

So the third choice is correct.

Let try plugging in values for x.

y= -4(0) + 98 = 98

y= -4(1) + 98 = 94

y= -4(2) + 98 = 90

x stands for the number of days the students miss.

We see the bigger the value we put in for x, the lower the test score is aas represented by y.

So, the sixth choice is correct.

we know that,

y intercept exist when x = 0

so,

⇢y = -4x +98

⇢y = -4 x 0 +98

⇢y = 98

so , the expected test score is 98

when x = 0

y = -4(0) +98

when x = 1

y= -4(1) +98 = 94

when x = 2

y= -4(2) +98 = 90

we can see the decresement of 4 points

We can see that the increament in absent days lead to lower scores ( one class = 4 points)

Answer:

x = 10

Step-by-step explanation:

Since the pentagons are similar you can say...

4x cm/48 cm = x cm/(x+2) cm

Now do cross multiplication with this equation, so 4x is multiplied with (x+2) and 48 is multiplied with x... you end up with:

4x^2+8x = 48x, now subtraction 8x from 48 x....

4x^2 = 40x, and divide one x from each side

4x = 40, therefore x = 10

x = -8

x = 3

x = -15

The explanation:

5x + 20 = 3x + 4

5x = 20 - 20 = 3x + 4 - 20

subtract = subtract = 5x = 3x - 16

5x = 3x - 16

5x - 3x = 3x - 16 - 3x

7x - 4 = 3x + 8

7x - 4 + 4 = 3x + 8 + 4

7x = 3x + 12

7x = 3x + 12

7x - 3x = 3x + 12 - 3x

2x + 6 = x - 9

2x + 6-6 = x - 9-6

2x = x - 15

2x = x - 15

2x - x = x - 15 - x

x = - 15

Given that the parent function, y = x², has a leading coefficient of 1, the

following are the comparisons of the equations with the parent functions;

[tex]\begin{array}{|c|cc|}Steeper \, than \, y = x^2&&Less \, Steep \ than \, y = x^2 \\y = 2 \cdot x^2&&y = \frac{1}{2} \cdot x^2 \\y = \left(2 \cdot x \right)^2&&y = \left(\frac{1}{2} \cdot x \right)^2 \end{array}\right][/tex]

The parent function is y = x²

The leading coefficient of the parent function = 1

The steepness of a quadratic equation is given by the value of the

leading coefficient.

When the leading coefficient is larger than 1, we have;

The function is steeper than y = x²

When the leading coefficient is a fraction larger than 0 but lesser than 1, we have;

The function is less steep than y = x²

Which gives;

[tex]\begin{array}{|c|cc|}Steeper \, than \, y = x^2&&Less \, Steep \ than \, y = x^2 \\y = 2 \cdot x^2&&y = \frac{1}{2} \cdot x^2 \\y = \left(2 \cdot x \right)^2&&y = \left(\frac{1}{2} \cdot x \right)^2 \end{array}\right][/tex]

The function y = -x² is inverted has the same steepness as y = x², but will not be used.
