A parallelogram is an easy quadrilateral with two pairs of parallel aspects. the other or dealing with facets of a parallelogram are of equal length and the other angles of a parallelogram are of equal measure. Hence, proved  p + q = r.

A parallelogram has four sides overall and two pairs of facets that might be parallel. A square is a parallelogram that has four equal sides. the other facets are parallel and all corners of the rectangular shape the right attitude. A rectangle is a parallelogram that has 4 contrary, parallel, congruent aspects.

proving p + q = r;

q = ∠OCD = ∠BAO   ( alternate angle)

In Δ AOB

∠OAb  + ∠DBA = p + q -------------------(1)

& ∠AOD + ∠BOA = 180° ------------(2)

Also,

∠OAB + ∠OBA + ∠BOA = 180° --------- some of angle in a triangle.

⇒ ( p + q) + (180° - ∠BOA) = 180° --------using 1 & 2

⇒  p + q - r = 0

⇒  p + q = r

you invest 1,000 in an account that pays simple interest of 3% for 10 years. what is the amount of money you'll have at the end of the 10 years?

Answers

Given data:

The given principal is P=1,000.

The given rate of interest is r=3%.

The given time is t=10 years.

The expression for the final amount after 10 years is,

[tex]A=P+\frac{P\times r\times t}{100}[/tex]

Substitute the given values in the above expression.

[tex]\begin{gathered} A=1,000+\frac{1,000\times3\times10}{100} \\ =1,300 \end{gathered}[/tex]

Thus, the final amount after 10 years is 1,300.

if you roll a dice twice, what is the possibility of getting a number less than 5 on both rolls?

Answers

Solution

Step 1

Write an expression for the probability of an event

[tex]\begin{gathered} \text{If an event is A} \\ P(A)\text{ = }\frac{No\text{ of required events}}{No\text{ of total possible events}} \end{gathered}[/tex]

No of the required events can be found with the following table

The numbers(1,2,3,4,5,6) on the vertical are for one dice and the others on the horizontal are for the second dice

No of required of numbers on both dices less than 5 are : 1,1 1,2 1,3 1,4 2,1 2,2 2,3 2,4 3,1 3,2 3,3 3,3 3,4 4,1 4,2 4,3 4,4. The number of the events are therefore, = 16

No of total events = 36

Step 2

Substitute the values and find the required probability

[tex]\text{Probability of getting numbers less than 5 on both dice = }\frac{16}{36}=\text{ }\frac{4}{9}[/tex]

11. The list price of an orange dial Luminox watch is $450. Katz Jewelers receives a tradediscount of 25%. Find the trade discount amount and the net price.

Answers

In order to find the trade discount amount and the net price, you first calculate the 25% of $450. You proceed as follow:

(25/100) x 450 = 112.5

the percentage is divided by 100, an

Then, $112.5 is the 25% of $450. And $112.5 is the discount amount

Next, to calculate the net price, you simply calculate the difference between the intial price ($450) and the price after the discount ($112.5), just as follow:

net price = $450 - $112.5 = $337.5

Hence, the discount amount is $112.5 and the net price is $337.5

Answers

Answer:

Explanation:

Here, we want to get the number of cars to be made so as to minimize the unit cost

What we have to do here is to find the first derivative of the given cost function

Mathematically, we have that as:

[tex]C^{\prime}(x)\text{ = 0.6x -96}[/tex]

To get the minimum x value, we simply set the first derivative to zero and solve for x

Mathematically, that would be:

[tex]\begin{gathered} 0\text{ = 0.6x-96} \\ 0.6x\text{ = 96} \\ x\text{ = }\frac{96}{0.6} \\ x\text{ = 160 } \end{gathered}[/tex]

A rocket is launched straight up with a velocity of 8.36. What would be the velocity when it lands?

Answers

If the rocket is launched straight up with a velocity of 8.36 then at the velocity of landing the speed of the rocket will also be 8.36.

Given that the rocket is launched straight up with a velocity of 8.36.

We are required to find the velocity when the rocket lands.

Velocity is basically the directional speed of a object in motion as an indication of its rate of change in position as observed from a particular frame of reference.

When the velocity of rocket while it goes up is 8.36 then the velocity when it lands is also 8.36 because if the velocity will increase then the rocket will crash also.

Hence if the rocket is launched straight up with a velocity of 8.36 then at the velocity of landing the speed of the rocket will also be 8.36.

Find the approximate area between the curve and the x-axis on the interval using 4 rectangles. Use the left endpoint of each rectangle to determine the height.

Answers

We have to approximate the area under the curve using the given rectangles.

Each rectangle will have an area that is equal to the width (the interval Δx) times the height (that is f(xi)).

We can express the formula for the approximation as:

[tex]A=\sum_{i=1}^4f(x_i)\cdot\Delta x=\sum_{i\mathop{=}1}^4f(x_i)(x_{i+1}-x_i)[/tex]

We will have to calculate f(x) for x = 0, 4, 8 and 12, which are the left endpoints of the interval for each rectangle.

Given that f(x) is defined as:

[tex]f(x)=-2x^2+32x+5[/tex]

we can calculate each value as:

[tex]f(0)=-2(0)^2+32(0)+5=5[/tex][tex]\begin{gathered} f(4)=-2(4)^2+32(4)+5 \\ f(4)=-2(16)+128+5 \\ f(4)=-32+128+5 \\ f(4)=101 \end{gathered}[/tex][tex]\begin{gathered} f(8)=-2(8)^2+32(8)+5 \\ f(8)=-128+256+5 \\ f(8)=133 \end{gathered}[/tex][tex]\begin{gathered} f(12)=-2(12)^2+32(12)+5 \\ f(12)=-288+384+5 \\ f(12)=101 \end{gathered}[/tex]

How far do the pigeons have to fly to go directly from Robin's house to Dovey's house? Round your answer to the nearest tenth. (HINT: draw a picture!) *

Answers

Let the north and east with a positive sign, so, the south and west are negative signs

Because of one-way streets, they go 3.1 km north, turn right and go 1.7 km east, turn left and go 2.3 km north, turn right and go 0.9 km east, turn left and go 1.2 km north, turn left and go 4.1 km west, and finally turn left and go 0.4 km south.

So, the resultant horizontal distance = 1.7 + 0.9 - 4.1 = -1.5 km

The resultant vertical distance = 3.1 + 2.3 + 1.2 - 0.4 = 6.2 km

So, the direct distance will be calculated using Pythagorean theorem :

So, the distance d =

[tex]\begin{gathered} d=\sqrt[]{(-1.5)^2+(6.2)^2}=\sqrt[]{2.25+38.44} \\ \\ d=\sqrt[]{40.69}=6.37887 \end{gathered}[/tex]
