The man brought three buses for 9694820. One bus cost Rs352750
another us cost Rs 3029870. Find the cost of third bus.​

Answers

Answer:

Cost of 3 buses = 9694820

cost of 1 bus=352750

cost of another bus=3029870

cost of the third bus= 9694820-(352750+3029870)=6312200

1:prove that the tangent at the point (1,-2) to the circle x²+y²=5 also touches the circle x²+y²-8x+6y+20=0 .Also find the point of contact.
2:find the length of tangent to the circle
3x²+3y²-7x-6y=12 drawn from (6,-7)​

Answers

#1

Circle 1 has center at (0, 0)

The tangent passes through the center and point (1, -2).

Equation of tangent at (1, -2):

x*1 + y*(-2) = 5x - 2y = 5x = 2y + 5

If the same line is tangent to circle 2 then they have one common point.

Solve the system:

x = 2y + 5x² + y² - 8x + 6y + 20 = 0

Substitute x:

(2y + 5)² + y² - 8(2y + 5) + 6y + 20 = 04y² + 20y + 25 - 16y - 40 + 6y + 20 = 05y² + 10y + 5 = 0y² + 2y + 1 = 0(y + 1)² = 0y + 1 = 0y = -1 ⇒ x = 2(-1) + 5 = -2 + 5 = 3

We see only one point of contact, (3, -1), this proves the line is tangent to circle 2 as well.

#2

Given circle:

3x² + 3y² - 7x - 6y = 12 and external point (6, -7).

Rewrite the equation of the circle as:

3x² + 3y² - 7x - 6y = 12x² + y² - 7/3x - 2y = 4x² - 2*7/6x + 49/36 + y² - 2y + 1 = 4 + 49/36 + 1(x - 7/6)² + (y - 1)² = 229/36

The center is (7/6, 1) the radius is √229/36

The length of the tangent t is the leg of the right triangle with another leg r being the radius and the hypotenuse d being the distance between the center and the external point:

t² = d² - r²t² = (6 - 7/6)² + (-7 - 1)² - 229/36t² = 36 - 14 + 49/36 + 64 - 229/36t² = 86 - 180/36t² = 81t = 9

Answer:

A = 39 ft²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 6, b₁ = 9, b₂ = 4 , then

A = [tex]\frac{1}{2}[/tex] × 6 × (9 + 4) = 3 × 13 = 39 ft²



The height of a triangle is 2 m more than twice the length of the base. The area of the triangle is 30 m2. Find the height of the
triangle.

Answers

Answer:

Step-by-step explanation:

Let x be the height ..... then the base = 2x + 2

So we have

Area = (1/2) (base) (height)

20 = (1/2)(2x + 2)(x) simplify

20 = x (x + 1)

20 = x^2 + x subtract 20 from both sides

x^2 + x - 20 = 0 factor

(x + 5) ( x - 4) = 0

Only the second factor makes sense

x - 4 = 0 add 4 to both sides

x = 4 ft and this is the height

And the base = 2(4) + 2 = 10 ft

Answers

Respuesta:

Explicación paso a paso:

Distancia total recorrida caminando de C a A pasando por T:

500 yardas + 700 yardas = 1200 yardas

Tiempo necesario para recorrer 200 yardas = 14 minutos

Caminando directamente de C a A:

La distancia se puede obtener usando una relación trigonométrica:

Hipotenusa = √ (opuesto² + adyacente²)

Hipotenusa = √500² + 700²

Hipoteno = 860.23252 yardas

Por eso ; Si

1200 yardas = 14 minutos

860.23252 yardas = x

Multiplicar en cruz:

1200x = 12043,255

x = 12043,255 / 1200

x = 10.036 minutos

El tiempo necesario para caminar directamente será: 10.0 minutos

How do i do this math equasion?

Answers

Answer:

f(t) = -16t² + 36

Step-by-step explanation:

f(t) = a(t - h)² + k

This is vertex form where (h, k) is the (x, y) coordinate of the vertex

The vertex is give as (0, 36)

f(t) = a(t - 0)^2 + 36

f(t) =at² + 36

use point (1, 20) to find "a"

20 = a(1²) + 36

20 = a + 36

-16 = a

f(t) = -16t² + 36

What is the slope of the line that passes through (a,b) and (1/a,b)?

Answers

Answer:

slope = 0

Step-by-step explanation:

Since the y- coordinates of both points are equal, both b

This indicates the line is horizontal and parallel to the x- axis

The slope of the x- axis is zero then the slope of the line is zero

Answer:

slope of the line is 0

Step-by-step explanation:

(a , b)=(x1 , y1)

(1/a , b)=(x2 , y2)

slope=y2 -y1/x2 -x1

=b-b/ 1/a -a

=0/1-[tex]a^{2}[/tex]/a

=0*a/1-[tex]a^{2}[/tex]

One of the solutions to x2 − 2x − 15 = 0 is x = −3. What is the other solution?

x = −5
x = −1
x = 1
x = 5

Answers

Answer: x = 5

Step-by-step explanation:

x² - 2x - 15 = 0

x² + 3x - 5x - 15 = 0

x(x + 3) - 5(x + 3) = 0

Therefore, x + 3 = 0

x = 0 - 3 = -3

Also, x - 5 = 0

x = 0 + 5 = 5

Therefore, the solutions to x² - 2x - 15 = 0 is x = -3 and x = 5. Therefore, the correct option is D.

Now suppose that bigger cups are ordered and the machine’s mean amount dispensed is set at μ=12. Assuming we can precisely adjust σ, what should we set σtobe so that the actual amount dispensed is between 11 and 13 ounces, 95% of the time?

Answers

Answer:

σ should be adjusted at 0.5.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean 12.

Assuming we can precisely adjust σ, what should we set σtobe so that the actual amount dispensed is between 11 and 13 ounces, 95% of the time?

13 should be 2 standard deviations above the mean of 12, and 11 should be two standard deviations below the mean.

So 1 should be worth two standard deviations. Then

[tex]2\sigma = 1[/tex]

[tex]\sigma = \frac{1}{2}[/tex]

[tex]\sigma = 0.5[/tex]

σ should be adjusted at 0.5.

Answers

Answer:

45 is 54.9 percent of 82.

26 is 520% of 5.

Answer:

45 is 55% of 82 and 520% of 5 is 26.

Step-by-step explanation:

First you want to set up a proportion, using the is over of formula (Is/of= %/100). In the first problem, 45 will be the is, 82 will be the of, for % will be the x, and 100 will go on the bottom (it will look something like this: 45/82=x/100). When you solve it, you get around 55 (45x100/82.) Same thing for the next equation, use the same formula (is/of=%/100) which turns into: 5/26= x/100 and you get 520%.

Angles that form a straight line add up to equal 180

Subtract both sides by 78

180 - 78 = 102

78 - 78 cancels out

The average height of BYU freshman from a random sample of 450 freshman at BYU is 68 inches with a standard deviation of 1.5 inches. What is the 98% confidence interval for the average height of BYU freshman?
a. (59.86, 60.14)
b. (67.83, 68.17)
c. (66.5. 69.5)
d. (67.86, 68.14)

Answers

Answer:

b. (67.83, 68.17)

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.98}{2} = 0.01[/tex]

Now, we have to find z in the Z-table as such z has a p-value of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.01 = 0.99[/tex], so Z = 2.327.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 2.327\frac{1.5}{\sqrt{450}} = 0.17[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 68 - 0.17 = 67.83.

The upper end of the interval is the sample mean added to M. So it is 68 + 0.17 = 68.17.

This means that the correct answer is given by option B.
