Which equation, when graphed, has x-intercepts at (−1, 0) and (−5, 0) and a y-intercept at (0, −30)?

Answers

Answer 1

Answer:

y = -6x^2 - 36x - 30

Step-by-step explanation:

X intercepts are the roots

y = a(x + 1)(x + 5)

to find "a" use point (0, -30)

-30 = a(1)(5)

-30 = a(5)

a = -6

therefor

y = -6(x + 1)(x + 5)

Expanded form

y = -6x^2 - 36x - 30

Which Equation, When Graphed, Has X-intercepts At (1, 0) And (5, 0) And A Y-intercept At (0, 30)?

Two airplanes leave an airport at the same time, the first headed due north and the second at a bearing of N42^ E . At 2:00PM, the first airplane is 312 miles from the airport while the second airplane is 487 miles from the airport. Assuming both followed linear paths from the airport, how far apart are the two airplanes at 2:00PM?

Answers

Answer:

The two airplanes are about 330miles apart.

Step-by-step explanation:

The diagram interpreting the question has been attached to this response.

As shown in the diagram,

i. the airplanes leave at point C.

ii. at 2.00pm the first and second airplanes are at points A and B respectively, where they are 312miles and 487miles away from the starting point C in directions due north and N42E from the point C.

iii. the points A, B and C form a triangle with sides a, b and c.

To solve for the value of c which is the distance between the two planes at 2.00pm, the cosine rule is used.

c² = a² + b² - 2abcosC            --------------(i)

where;

b  = 312miles

a = 487miles

C = 42°

Substitute these values into equation (i) and solve as follows;

c² = (487)² + (312)² - 2(312)(487)cos(42)

c² = (237169) + (97344) - 303888cos(42)

c² = (237169) + (97344) - 303888(0.7431)

c² = 334513 - 225819.1728

c² = 108693.8272

Take the square root of both sides

√c² = √108693.8272

c = 329.69

c ≅ 330miles

Therefore, the two airplanes are far apart by 330miles

Answers

Answer:

1;50

Step-by-step explanation:

The ratio shows how many times one value is contained in another value.

The ratio equivalent to the scale of 1cm/50mi is 1:50.

Option A is the correct answer.

What is a ratio?

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

The ratio is written in the form of a numerator and a denominator.

Now,

1cm / 50 miles is in the form of a numerator and a denominator.

Now,

1cm : 50 miles = 1cm / 50 miles

= 1:50

Thus,

The ratio equivalent to the scale of 1cm/50mi is 1:50.

Option A is the correct answer.

The point C (-3,-1) is rotated 180 clockwise around the origin.


What are the coordinates of the resulting point, C'?

Answers

Answer: [tex](3,1)[/tex]

Step-by-step explanation:

Given

The point C [tex](-3,-1)[/tex] is rotated [tex]180^{\circ}[/tex] clockwise about the origin

If a point is rotated [tex]180^{\circ}[/tex] about the origin, then the sign of the co-ordinates changes without changing the order of coordinates.

So,C  [tex](-3,-1)[/tex] becomes C' [tex](3,1)[/tex] after the rotation.

A car comes to a stop six seconds after the driver applies the brakes. While the brakes are on, the following velocities are recorded:
Time since brakes applied (sec) 0 2 4 6
Velocity (ft/s) 97 49 18 0
Give lower and upper estimates (using all of the available data) for the distance the car traveled after the brakes were applied.

Answers

Answer:

Hence, the Lower estimates are [tex]134[/tex] and the upper estimates are [tex]228[/tex] feet

Step-by-step explanation:

A car comes to a stop six seconds after the driver applies the brakes. While the brakes are on, the velocities recorded are given in the question.

So, the Lower Estimates for the distance travelled by car will be

    [tex]S=49\cdot 2+18\cdot 2+0\cdot 2[/tex]

[tex]\Rightarrow S=98+36+0[/tex]

[tex]\Rightarrow S=134[/tex]

Also, the Upper estimates for the same will be

     [tex]S=97\cdot 2+49\cdot2+18\cdot 2[/tex]

[tex]\Rightarrow S=194+98+36[/tex]

[tex]\Rightarrow S=228[/tex]
