The possible coordinates of C and D are: C = (11,3) and D = (11,-5) or C = (-3,3) and D = (-3,-5)

The given parameters are:

A = (4,3)

B = (4,-5)

Perimeter, P = 30 units

Since points A and B are on the same x-coordinate, then the distance between them is:

AB = 3 - - 5

AB = 8

The perimeter of the rectangle is calculated using:

P = 2 *(AB + CD)

This gives

2 * (8 + CD) = 30

Divide by 2

8 + CD = 15

Subtract 8 from both sides

CD = 7

This means that points C and D are 7 units from points A and B, respectively.

If A = (4,3) and B = (4,-5), then the possible coordinates of C and D are:

C = (11,3) and D = (11,-5) or C = (-3,3) and D = (-3,-5)

a. The height of the ball after four seconds is 640 ft

b. The time the ball reachs a height of 768 ft is 6 s or 8 s.

c. The time the ball reachs the ground after it is thrown is 14 seconds.

Since the height of the ball is a parabola, we need to know the equation parabola is

A parabola is an equation of the form x(t) = at² + bt + c

The height of the ball after four seconds is 640 ft

Since the height of the ball is represented by the equation h(t) = -16t² + 224t. The height of the ball after four seconds is when t = 4.

So, h(t) = -16t² + 224t.

h(4) = -16(4)² + 224(4)

h(4) = -16(16) + 224(4)

h(4) = -256 + 896

h(4) = 640 ft

The height of the ball after four seconds is 640 ft

The time it takes the ball to reach a height of 768 ft is 6 s or 8 s.

To find this time, we substituie h = 768 into the equation for the height of the ball.

So, h(t) = -16t² + 224t

768 = -16t² + 224t.

16t² - 224t + 768 = 0

t² - 14t + 48 = 0

Using the quadratic formula, we find t

[tex]t = \frac{-(-14) +/- \sqrt{(-14)^{2} - 4 X 1 X 48} }{2 X 1} \\t = \frac{14 +/- \sqrt{196 - 192} }{2}\\t = \frac{14 +/- \sqrt{4} }{2}\\t = \frac{14 +/- 2 }{2}\\t = \frac{14 + 2 }{2} or t = \frac{14 - 2 }{2}\\t = \frac{16}{2} or t = \frac{12}{2}\\t = 8 or 6[/tex]

So, the time it takes the ball to reach a height of 768 ft is 6 s or 8 s.

The time it takes the ball to reach the ground after it is thrown is 14 seconds.

To find the time it takes the ball to reach the ground, the height, h = 0.

So, h(t) = 0

-16t² + 224t = 0

-16t(t - 14) = 0

t(t - 14) = 0

t = 0 or t - 14 = 0

t = 0 or t = 14 s

So, the time it takes the ball to reach the ground after it is thrown is 14 seconds.

The number of times Jennifer rolls a number less than 3 in a number cube when she rolls it 60 times is 40.

The probability of rolling a number less than 3 on a number cube is 2/6.

[tex]P( > 3)=\dfrac{2}{6}[/tex]

Step-by-step explanation:

The linear equation with a slope of 1 that passes through (3, 5) is:

y = x + 2.

The general linear equation is given by:

y = a*x + b

Where b is the y-intercept and a is the slope.

Here we know that the slope is 1, so we have:

y = x + b

And we also know that the line passes through (3, 5), then we must have that:

5 = 3 + b

We can solve that for b:

b = 5 - 3 = 2

So the linear equation is:

y = x + 2.

Here are the steps to solve for x:

3(x+4) + 2 = 2+5(x-4)

1. Distribute to get rid of the parentheses

3x+12+2 = 2+5x-20

2. Combine like terms

3x+14 = 5x -18

3. Get like terms on the same side

3x+14 = 5x -18

-14            -14

3x = 5x -32

Answer:

5% account = $1,240

10% account = $2,190

Step-by-step explanation:

Let's assume the amount of savings in the 5% account is x.

Thus the amount of savings in the 10% account is (x + $950).

We can write the following equation from the interest amount:

[5% x ] + [10% (x + $950)] = $281

5%x + 10%x + $95 = S281

15%x = $186

x = $1,240

There is $1,240 in the 5% account

Therefore, on the 10% account there is $1,240 + $950 = $2,190

I assume the given expression is

[tex]\sqrt x \sqrt[4]{x}[/tex]

We can write each root as a rational power of x, then add the exponents:

[tex]\sqrt x \sqrt[4]{x} = x^{\frac12} x^{\frac14} = x^{\frac12 + \frac14} = x^{\frac34}[/tex]

Then putting it back into radical form, we have

[tex]\sqrt x \sqrt[4]{x} = \sqrt[4]{x^3}[/tex]
