2. Given: ZMOP Is A Right Angle RP I OP Prove: MO || RP

Answers

Answer 1

Given that;

[tex]\begin{gathered} \measuredangle MOP\text{ is a right angle.} \\ \measuredangle MOP=90^0 \end{gathered}[/tex]

And;

[tex]\vec{RP}\perp\vec{OP}[/tex]

Since line RP is perpendicular to line OP, Angle RPO must be a right angle.

[tex]\measuredangle RPO=90^0[/tex]

Recall that for two parallel lines intersected by a straight line, Same side interior angles are supplementary.

[tex]A+B=180^0[/tex]

So, for line MO to be parallel to line RP, the sum of angle MOP and angle RPO must be equal to 180 degree.

[tex]\measuredangle MOP+\measuredangle RPO=90+90=180^0[/tex]

Since the sum of angle MOP and angle RPO is equal to 180 degree, then line MO is parallel to line RP.

The Neckware association of America reported that 3% of ties sold in the United States are bow ties. If 4 customers who purchased a tie randomly selected,find the probability that at least 1 purchased a bow tie

Answers

[tex]Pr(at\text{ least 1 purchased a bow tie) = 0.1147}[/tex]

Explanation:

Pr (people with bow ties) = 3% = 0.03

p = 0.03

Pr (people without bow tie) = 1 - 0.03 = 0.97

q = 0.97

n = 4 customers

[tex]Pr(at\text{ least 1 purchased a bow tie) = 1 - Pr(none purchased a bow tie)}[/tex]

To find the probability that at least 1 purchased a bow tie, we will use a binomial probability formula:

[tex]p(x=^{}X)=^nC_xp^xq^{n\text{ - x}}[/tex][tex]\begin{gathered} \text{Pr(none purchased a bow tie) = p(x = 0)} \\ \text{p(x = 0) = }^4C_0\times p^0\times q^{4\text{ - }0} \\ \text{p(x = 0) = 1 }\times\text{ 1}\times q^4=(0.97)^4 \\ \text{p(x = 0) = }0.8853 \\ \\ \text{Pr(none purchased a bow tie) = }0.8853 \end{gathered}[/tex][tex]\begin{gathered} Pr(at\text{ least 1 purchased a bow tie) = 1 - 0.8853} \\ Pr(at\text{ least 1 purchased a bow tie) = 0.1147} \end{gathered}[/tex]

Kala the trainer had two solo workout plans that she offers her clients. PlanA and plan B. Each client does either one or the other (not both) on Friday there were 3 clients who did plan A and 5 who did plan B. On Saturday there were 9 clients who did plan A and 7 who did plan B. Kala trained her Friday clients for a total of 6 hours and her Saturday clients for a total of 12 hours. How long does each of the workout plans last?

Answers

Answer:

Each of the workouts plans lasts 45 minutes.

Explanation:

Let the duration for Plan A workout = x

Let the duration for Plan B workout = y

Friday

• Plan A --> 3 clients

,

• Plan B --> 5 clients

,

• Kala trained her Friday clients for a total of 6 hours

Saturday

• Plan A --> 9 clients

• Plan B --> 7 clients

The system of equations is solved simultaneously.

[tex]\begin{gathered} 3x+5y=6\cdots(1) \\ 9x+7y=12\cdots(2) \end{gathered}[/tex]

Multiply equation (1) by 3 in order to eliminate x.

Subtract.

[tex]\begin{gathered} 8y=6 \\ y=\frac{6}{8}=0.75\text{ hours} \\ 0.75\times60=45\text{ minutes} \end{gathered}[/tex]

Substitute y=0.75 into equation (2) to solve for x.

[tex]\begin{gathered} 9x+7y=12 \\ 9x+7(0.75)=12 \\ 9x+5.25=12 \\ 9x=12-5.25=6.75 \\ x=\frac{6.75}{9} \\ x=0.75 \end{gathered}[/tex]

Jan plans to tell two people each day and will ask that person to tell two other people each day through the day of the opening, and so on. Assume that each new person who hears about the soft opening is also asked to tell two other people each day through the day of the opening and that each one starts the process of telling their friends on the day after he or she first hears. When should Jan begin telling others about the soft opening in order to have at least 700 people know about it by the day it occurs?

Answers

Explanation:

From the given question, we can sketch the pattern observed

The figure above helps show how the number of people increases

Initially, Jan tells 2 more people, then the two people tell two more people, then they also tell two more people

Thus

we can see that the model is given by

[tex]\begin{gathered} (2)^n \\ where\text{ n is the number of days} \end{gathered}[/tex]

In order to have at least 700 (it also means a minimum of 700), we will have the equation

[tex]2^n\ge700[/tex]

We then solve for n

Taking the log of both sides

[tex]n\text{ }log2\ge log700[/tex][tex]n\ge\frac{log700}{log2}[/tex]

So that

[tex]\begin{gathered} n\ge\frac{2.845}{0.301} \\ \\ n\ge9.451 \end{gathered}[/tex]

So, the number of days will be at least 10 days (Rounded to the nearest whole day )

Equation of line passing thru point -6,-3 and perpindicular to JK -2,7 and 6,5

Answers

Equation of the line passing through the point (-6,-3) and perpendicular to  the line passing through (-2,7) and (6,5) is y = 4x -19.

First we will find the slope of the line passing through (-2,7) and (6,5).

Slope of the line = (5-7)/(6-(-2)) = -2/8 = -1/4.

We know that,

Product of the slopes of two perpendicular lines = -1.

Let the equation of the line we have to find be y = mx + c.

Slope will be m.

Hence, we can write,

m*(-1/4) = -1

m = -1*(-4/1)

m = 4

Putting (6,5)  and m = 4 in y = mx + c , we get

5 = 4*(6) + c

5 = 24 + c

c = 5 - 24 = -19

Hence, the equation of the line is:-

y = 4x -19

The dimensions of the rectangular prism of 6 cm by 3 cm by 2 cm and the dimension of the cube of 3 cm gives the amount the surface area of the prism is greater than the cube as 18 cm²

What is a rectangular prism?

A rectangular prism is a six faced solid hexahedron.

The given dimension of the rectangular prism are:

Length = 6 cm

Height = 3 cm

Width = 2 cm

The side length of the cube = 3cm

The surface area of the rectangular prism is therefore:

[tex]A_p[/tex] = 6 × 3 × 2 + 6 × 2 × 2 + 3 × 2 × 2 = 72

The surface area of the rectangular prism is 72 cm²

The surface area of the cube: [tex]A_c[/tex] = 6 × 3² = 54

The surface area of the cube, [tex]A_c[/tex] = 54 cm²

The amount by which area of the rectangular prism is greater than the area of the cube is therefore: [tex]A_p[/tex] - [tex]A_c[/tex] = 72 cm² - 54 cm² = 18 cm²

Line segment AB is on square ABCD. Segment EF on equilateral triangle EFG is 12 units longer than AB. Square ABCD and triangle EFG have equal perimeters. What is the length of AB?

Answers

The length of segment AB as required in the task content is; 36.

What is the length of segment AB?

It follows from the task content that the length of the line segment AB which is a side of the square ABCD is to be determined.

Since the perimeters of triangle EFG and square ABCD are equal as given;

Let the length of segment AB = x.

Therefore, EF = x + 12.

Therefore, the perimeter of the equilateral triangle = 3(x +12).

While the perimeter of square ABCD is; 4x.

Therefore, since the perimeters are equal;

3(x + 12) = 4x

3x + 36 = 4x

36 = x.

Compute the sums below. (Assume that the terms in the first sum are consecutive terms of an arithmetic sequence.) 9 + 4 + (-1) + ... + (-536)

SOLUTION

The terms below make an A.P. Now we are told to find the sum of the AP.

Sum of an AP is given by

[tex]S\text{ = }\frac{n}{2}\lbrack2a\text{ + (n-1)d\rbrack}[/tex]

Where S = sum of the AP, a = first term = 9, d = -5, n= ?

So we have to find n first before we can find the sum. The nth term which is the last term = -536. So we will use it to find the number of terms "n"

[tex]\begin{gathered} \text{From T}_{n\text{ }}=\text{ a +(n-1)d where T}_{n\text{ }}=\text{ -536} \\ -536\text{ = 9+(n-1)-5} \\ -536\text{ = 9-5n+5} \\ -536\text{ = 14-5n} \\ -5n\text{ = -536-14} \\ -5n\text{ = -550} \\ n\text{ = 110} \end{gathered}[/tex]

Now let's find the sum

[tex]\begin{gathered} S\text{ = }\frac{n}{2}\lbrack2a\text{ + (n-1)d\rbrack} \\ S\text{ = }\frac{110}{2}\lbrack2\times9\text{ + (110-1)-5\rbrack} \\ S\text{ = 55\lbrack{}18+(119)-5\rbrack} \\ S\text{ = 55\lbrack{}18 - 595\rbrack} \\ S\text{ = 55}\times-577 \\ S\text{ = -31735} \end{gathered}[/tex]

Therefore, the sum = -31735
