Answer:

[tex]C = (30,500)[/tex]

Step-by-step explanation:

Given

[tex]Area = 1800ft^2[/tex]

[tex]A = (6,0)[/tex]

[tex]B = (0,25)[/tex]

[tex]C(x,y) = (30,y)[/tex]

Required

Determine the coordinates of C

The area of triangle is calculated as thus:

[tex]Area = \frac{|A_x(B_y - C_y) + B_x(C_y - A_y) + C_x(A_y - B_y)|}{2}[/tex]

This gives:

[tex]1800= \frac{|6(25 - y) + 0(y - 0) + 30(0 - 25)|}{2}[/tex]

[tex]1800= \frac{|6(25 - y) + 30(0- 25)|}{2}[/tex]

[tex]1800= \frac{|6(25 - y) + 30(-25)|}{2}[/tex]

[tex]1800= \frac{|150 - 6y -750 |}{2}[/tex]

[tex]1800= \frac{|150 -750- 6y |}{2}[/tex]

[tex]1800= \frac{|-600- 6y |}{2}[/tex]

Multiply through by 2

[tex]2 * 1800= |-600- 6y|[/tex]

[tex]3600= |-600- 6y|[/tex]

[tex]3600= |-(600+ 6y)|[/tex]

[tex]3600= 600+ 6y[/tex]

Solve for 6y

[tex]6y = 3600 - 600[/tex]

[tex]6y = 3000[/tex]

Solve for y

[tex]y = 3000/6[/tex]

[tex]y = 500[/tex]

Hence:

The point is:

[tex]C = (30,500)[/tex]

Answer:

x-int: (-1.2, 0)

y-int: (0, -0.7)

Step-by-step explanation:

The x-intercept is the x value when y = 0.

Another way to reword that is when the graph crosses the x-axis.

The y-intercept is the y value when x = 0.

Another way to reword that is when the graph crosses the y-axis.

According to the graph, when y = 0 and when the line crosses the x-axis, the x-value is -1.2. Therefore, our x-intercept is (-1.2, 0).

According to the graph, when x = 0 and when the line crosses the y-axis, the y-value is -0.7. Therefore, our x-intercept is (0, -0.7).

Answer:

Step-by-step explanation:

1) Upon studying the grid, we see that A is at the intersection of the x- and y-axes, and that all of the other points are in the first quadrant. The distance between minor grid lines in either direction is taken to be 1 unit. That is, B is 1 unit right and 1 unit up from A(0, 0), so has coordinates B(1, 1).

The coordinates of C and D can be found by counting grid lines. We find them to be C(5, 1) and D(8, 7).

__

2) The line joining A and B is a line whose points have their x-coordinate equal to their y-coordinate. The coordinates of D are not equal, so will not be on that line.

Answer:

3/32

Step-by-step explanation:

the reason it’s 3/32 is because you have to divide 3/4 divide by 8. So that means 3/4x1/8 and that gives you 3/32. I hope that helped you!

(1, -2) is the coordinates that exists on the line y = 2x - 4

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given is an equation of a line, we need to find that on which of the given points it lies,

So, we will put the points one by one, the point which stratify the equation will be the answer.

The equation :- y = 2x-4

1) (1, -2)

Put x = 1, y = -2 in the equation,

2(1)-4

= 2-4 = -2

LHS = RHS

Since, point (1, -2) satisfy the equation therefore, the line will pass through it.

Hence, (1, -2) is the coordinates that exists on the line y = 2x - 4

Answer:

The system of inequalities describes Tamara’s investment options are as follows:

[tex]8000\leq x[/tex]

[tex]3y\leq x[/tex]

Step-by-step explanation:

Total amount with Tamara = $30,000

Let [tex]x[/tex] be the amount invested in corporate bonds, and let [tex]y[/tex] be the amount invested in municipal bonds.

She wants to invest no less than $8,000 into corporate bonds.

So, the inequality is [tex]8000\leq x[/tex]    

Also, she wants to invest at least three times as much into corporate bonds than into municipal bonds.

[tex]3y\leq x[/tex]    

The system of inequalities describes Tamara’s investment options are as follows:

[tex]8000\leq x[/tex]

[tex]3y\leq x[/tex]

Answer:

The number of students to be sampled is [tex]n = 1789 [/tex]

Step-by-step explanation:

From the question we are told that

  The margin of error is  E = 0.03

Generally the proportion of students that receive financial aid is mathematically represented as  

          [tex]\^ p = \frac{118 }{200}[/tex]

=>        [tex]\^ p = 0.59[/tex]

From the question we are told the confidence level is  99% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  2.58 [/tex]

Generally the sample size is mathematically represented as

     [tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]

=>  [tex]n = [\frac{2.58}{0.03} ]^2 * 0.59(1 - 0.59) [/tex]

=>  [tex]n = 1789 [/tex]

Using the margin of error, it is found that 1033 students would need to be sampled.

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

The margin of error is of:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

The dean randomly selects 200 students and finds that 118 of them are receiving financial aid, hence, the estimate is:

[tex]\pi = \frac{118}{200} = 0.59[/tex]

99% confidence level

So [tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so [tex]z = 2.575[/tex].  

The sample size needed is n when M = 0.03, hence:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.96\sqrt{\frac{0.59(0.41)}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.96\sqrt{0.59(0.41)}[/tex]

[tex]\sqrt{n} = \frac{1.96\sqrt{0.59(0.41)}}{0.03}[/tex]

[tex]\sqrt{n}^2 = \left(\frac{1.96\sqrt{0.59(0.41)}}{0.03}\right)^2[/tex]

[tex]n = 1032.5[/tex]

Rounding up, it is found that 1033 students would need to be sampled.

Answer:

See below

Step-by-step explanation:

As CD⊥AB, ∠BDC = ∠ADC = 90°

∠BDC ≅ ∠ADC

and

We can substitute ∠ADC with ∠BDC and ∠DAC with ∠DBC

Then we get same equation for ∠BCD and ∠ACD

Therefore ∠BCD = ∠ACD = 1/2∠ACB

It proves that CD bisects ∠ACB
