A ball has a diameter of 14 inches. Which choice is closest to its surface area? Use 3.14 to approximate pi.

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

simplify:
4 x pi x 49

simplify:
12.56 x 49

simplify:
615.44 inches

the answer is above in bold

Ava graphs the function h(x) = x2 + 4. Victor graphs the function g(x) = (x + 4)2. Which statements are true regarding the two graphs? Check all that apply. Ava’s graph is a vertical translation of f(x) = x2. Victor’s graph is a vertical translation of f(x) = x2. Ava’s graph moved 4 units from f(x) = x2 in a positive direction. Victor’s graph moved 4 units from f(x) = x2 in a positive direction. Ava’s graph has a y-intercept of 4. Victor’s graph has a y-intercept of 4.

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  h(x) = x^2 + 4.

Victor graphs the function  g(x) = (x + 4)^2

To find y intercept we plug in 0 for x

 h(x) = x^2 + 4

 h(x) = 0 + 4= 4

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

Ava graphs the function  h(x) = x^2 + 4

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  g(x) = (x + 4)^2

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

What number should be added to both sides of the equation to complete the square? x2 – 10x = 7

we have

x^{2} -10x=7

Complete the square. Remember to balance the equation by adding the same constants to each side

to complete the square adds (10/2)^{2}=25 both sides

so

x^{2} -10x+25=7+25

x^{2} -10x+25=32

Rewrite as perfect squares

(x-5)^{2}=32

Square root both sides

x-5=(+/-)\sqrt{32}

x=5(+/-)\sqrt{32}

x1=5+\sqrt{32}

x2=5-\sqrt{32}

therefore

the answer is

The number is 25

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

Jillian’s school is selling tickets for a play. The tickets cost $10.50 for adults and $3.75 for students. The ticket sales for opening night totaled $2071.50. The equation 10.50a + 3.75b = 2071.50, where a is the number of adult tickets sold and b is the number of student tickets sold, can be used to find the number of adult and student tickets. If 82 students attended, how may adult tickets were sold?

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.
I hope I helped! =D

Which equation has a graph that is a parabola with a vertex at (-2,0)

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.

A square is inscribed in a circle that has a radius of 2√2 inches. What is the length of the side of the square?

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

              (side)²  =  16

               side  =    4 inches

The area of a triangle whose height is 1 more than 6 times its base is 13 square feet. if the base of a triangle is x feet which equation models

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.

Triangle HIJ has coordinates H(–1, 1), I(1, 4), and J(1, 3). Graph the triangle and its translation 3 units to the right and 2 units down. What are the coordinates of I.

Answer:

(4,2)

Step-by-step explanation:

We have been given that triangle HIJ has coordinates H(-1,1), I(1,4) and J(1,3). We are asked to find the coordinate of point I after a translation of 3 units to the right and 2 units down.

The translation of 3 units to right means that we need to add 3 to x-coordinates.

The translation of 2 units down means that we need to subtract 2 from y-coordinates.

H(-1,1)\rightarrow H'(-1+3,1-2)=H'(2,-1)

I(1,4)\rightarrow I'(1+3,4-2)=I'(4,2)

J(1,3)\rightarrow J'(1+3,3-2)=I'(4,1)

Therefore, the coordinates of point I' after translation would be (4,2).

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

The maximum rate at which a bus can accelerate or decelerate is 2m/s^2 it has a maximum speed of 60km/h. Find the shortest time the bus can take to travel between two bus stops 1 km apart on a straight stretch of road.

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.

Answer:

Correct option is:

A. $125.91

Step-by-step explanation:

Cost of each CD= $13.99

Cost of 9 CDs= $13.99×9

                      = $ 13.99(10-1)

                      = $ (13.99×10-13.99×1)   (using distributive property)

                       = $ (139.9-13.99)

                       = $125.91

Hence, Correct option is:

A. $125.91
