The correct and best answer would be letter B. To find the percent of a discount, you have to find or solve for the percent of increase from the new price to the original price. This is because you usually have the new price being given to you so you compare it with the old price to know the percent discount.

So we know the formula to find the surface area of a sphere (ball) is:

4 x pi x r^2

to find the radius, divide the diameter by 2 to get:

14 / 2 = 7

now we substitute in the values:

4 x pi x 7^2

**Answers:**

**Ava’s graph is a vertical translation of f(x) = x^2.
**

**Ava’s graph moved 4 units from f(x) = x^2 in a positive direction.
**

**Ava’s graph has a y-intercept of 4.
**

Given:

Ava graphs the function .

Victor graphs the function

To find y intercept we plug in 0 for x

= 4

So ,Ava’s graph has a y-intercept of 4.

Ava graphs the function

If any number is added at the end then the graph will be shifted up. 4 is added at the end so there will be vertical translation.

Hence , Ava’s graph is a vertical translation of f(x) = x^2. Also Ava moved 4 units up from f(x) = x^2 in a positive y- direction.

Victor graphs the function

If any number added with x then the graph will be shifted left. the graph will be shifted in negative x direction.

QUESTION POSTED AT 22/01/2020 - 02:17 AM

Okay, so this is a multi-step problem. If there are 82 students, and the cost was $3.75 PER student, we would multiply 3.75 times 82 to get 307.50, and now we would subtract the total amount of sales, ($2,071.50), MINUS the ticket sales made by students, ($307.50). So 2,071.50 - 307.50 = 1,764.

So this means that they made $1,764 in ticket sales from ADULTS. Now to find out how many adults were THERE, (or the amount of adult tickets that were sold), we will divide 1,764 divided by the price of each adult ticket, ($10.50), which will be 1,764 divided by 10.50 = 168.

**168 adult tickets were sold.**

**Answer:**

**The required equation of the parabola : y = x² + 4 + 4x**

**Step-by-step explanation:**

**The vertex of the parabola is given to be : (-2 , 0)**

The equation of a parabola with a vertex at (h , k) is : f(x) = a(x - h)² + k , where a is a constant not equal to zero.

Now, Vertex : ( h , k) = (-2 , 0)

So, h = -2 and k = 0

⇒ f(x) = a(x + 2)² + 0

⇒ y = a(x + 2)²

Take a = 1

**⇒ y = x² + 4 + 4x**

**This is the required equation of the parabola.**

When a square (or any rectangle) is inscribed in a circle, the diagonal

of the square (or rectangle) is a diameter of the circle.

Diagonal of this square = diameter = 2 x radius = 4√2 inches.

But the diagonal of a square is the hypotenuse of the right triangle that's

formed by cutting the square in half corner-to-corner.

So (diagonal)² = (side)² + (side)²

2 (side)² = (diameter)²

2 (side)² = (4√2)²

2 (side)² = 16 x 2 = 32

Since the choices were not given, the ones below were retrieved from another source:
A) 6x^2+x-12=0
B) 6x^2+x-13=0
C) 6x^2+x-26=0
D) 36x^2+6x-26=0
If we let x represent the dimension of the base, then
we can represent height as (6x +1).
Since the area of the triangle is equal to bh/2, we can express the area in terms of x as
x(6x + 1)/2 and equate in to 13. Thus
x(6x + 1)/2 = 13
x(6x + 1) = 26
6x² + x = 26
6x² + x - 26 = 0
Thus, the answer is 6x² + x - 26 = 0.

QUESTION POSTED AT 22/01/2020 - 01:57 AM

Question did not specify that bus was stationary at any point.

60 km/h = 60000/3600 m/s = 16.67 m/s

Shortest time to travel = distance / speed = 1000/(50/3)=60 sec. = 1 min.

If we assume bus was stationary at each stop (if passengers have to get on/off), then acceleration is involved.

Note: at 2 m/s, the bus accelerates from stationary to 60 km/h in 8 seconds!

Using kinematics equation

2aS=v^2-u^2

we have

a=acceleration = 2m/s

S=distance

u=0 initial speed

v=final speed=50/3 m/s=60 km/h

Distance travelled = (v^2-u^2)/(2a)=(50/3)^2/(2*2)=625/9 m=69.33 m.

Remaining distance at 60 km/h

=1000-69.44-69.44=861.11 m

time to travel = 861.11/(50/3)=51.67 s.

Time to accelerate/decelerate= (50/ 3)/2 m/s / m/s^2 = 8.333 s.

Total time = 51.67+2*8.33=68.33 s.

60 km/h = 60000/3600 m/s = 16.67 m/s

Shortest time to travel = distance / speed = 1000/(50/3)=60 sec. = 1 min.
