The vertex of this parabola is at (3, 5) . When the y-value is 6, the x-value is - 1 What is the coefficient of the squared term in the parabola's equation? (3, 5) A. -4 B. 4 C. 2 D.2

Answers

Answer:

The correct approach is Option A (-4).

Step-by-step explanation:

The given values are:

Vertex of the parabola,

(h, k) = (3, 5)

Passing through,

(x, y) = (-1, 6)

As we know,

The equation of parabola is:

⇒  [tex]x=a(y-k)^2+h[/tex]

On substituting the given values in the above equation, we get

⇒  [tex]-1=a(6-5)^2+3[/tex]

⇒  [tex]-1=a+3[/tex]

On substracting "3" from both sides, we get

⇒  [tex]-1-3=a+3-3[/tex]

⇒           [tex]a=-4[/tex] (coefficient of squared term)

Thus the above is the right choice.

if i got shorts for 30 dollars and the original price was 40 what was the discount​

Answers

Answer:

25%

Step-by-step explanation:

30/40 = 0.75 = 75% paid

100-75 = 25% discount

Answer:

[tex]25\%[/tex]

Step-by-step explanation:

To find the discount of an object, one must set up the equation, the difference between the original and the paid price, over the original price, equals percent over 100. In essence;

[tex]\frac{(original-paid)}{original}=\frac{percent}{100}[/tex]

Substitute in the given values;

[tex]\frac{(40)-(30)}{40}=\frac{percnet}{100}[/tex]

Solve;

[tex]\frac{10}{40}=\frac{percent}{100}[/tex]

Simplify,

[tex]\frac{1}{4}=\frac{percent}{100}[/tex]

Cross products,

[tex]100 = 4(percent)[/tex]

Inverse operations,

[tex]100=4(percent)\\/4\\\\25 = percent[/tex]

Aidan took a 1020 km trip, travelling by Bus and By Train. The bus travelled at 105 km/h, and the train travelled at 160 km/h. The whole trip took 8 Hours. How Far did he travel on the train? Solve algebraically, and round your final answer to one decimal place.

Answers

Answer:

  523.6 km

Step-by-step explanation:

Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...

  time = distance/speed

Then the total travel time in hours is ...

  x/160 +(1020-x)/105 = 8

  21x +32640 -32x = 26880 . . . . .  multiply by 3360

  5760 = 11x . . . . . . . . . add 11x -26880

  523.6 ≈ x . . . . . . . . . . divide by 11

Aidan traveled about 523.6 km by train.

A rectangular prism is filled with 356 cubes with an edge length of 1/4 what is the volume of this prism

Answers

Answer: volume = 5.5625 cubic units.

Step-by-step explanation:

A rectangular prism is filled with 356 cubes, then the volume of the prism will be equal to 356 times the volume of a single cube.

We know that for a cube with side length L, the volume is:

V = L^3

And we know that these small cubes have an edge length of 1/4 units.

Then the volume of each small cube is:

V = (1/4)^3 cubic units

V = (1/64) cubic units

And the volume of the prism will be 356 times that, then the volume of the prism is:

volume = 356*(1/64) cubic units

volume = 5.5625 cubic units.
