Alex threw a ball into the air. Its height (in feet) above ground after x seconds is given by f(x) = –2(x – 4) + 23. What's the maximum height of the ball above ground?

A) 29 feet

B) 15.5 feet

C) 23 feet

D) 31 feet

Answer:

$33.6667

Step-by-step explanation:

Given the following :

Number of Scarf designs = 6

Number of each made = 15

Total scarfs = (15 * 6) = 90

Cost:

Booth = $128

Production cost per scarf = $9.80

Total production cost = $9.80 * 90 = $882

Total cost = $128 + $882 = $1010

Break even = profit - loss = 0

One third of scarves = 1/3 * 90 = 30

This means he must cover for the total cost of $1010 after selling 30 scarves

Hence price per scarf will be :

$1010 / 30

= $33.6667

Answer:

x- intercept = 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2 and c = 6 , thus

y = - 2x + 6 ← is the equation of the line

To find the x- intercept, let y = 0 in the equation and solve for x

- 2x + 6 = 0 ( subtract 6 from both sides )

- 2x = - 6 ( divide both sides by - 2 )

x = 3 ← x- intercept or (3, 0 )

Answer:

5 2/3

Step-by-step explanation:

So because it is a mixed number that means you want to have a whole plus a fraction. You keep the 5 as the whole and because 2/3=.666666. You add them together making 5 2/3.

Step-by-step explanation:

Got it on Edge

Answer:

Answer in explanation

Step-by-step explanation:

The equation of a straight line can be represented in the form;

y = mx + c

where m is slope and c is y-intercept

In this particular case

y = 20x + 5

y is the weekly income, x is the number of lawns mowed

The y-intercept 5 is the amount earned in a week given they no lawn was mowed

In a case where y = 125

125 = 20x + 5

20x = 125-5

20x = 120

x = 120/20

x = 6

You need to mow 6 lawns to earn enough money in one week to buy the MP3 player

Answer:

x=24

Step-by-step explanation:

x=180-156

x= 24

Answer:

1x=864,

2y=3

Step-by-step explanation:

y=6,x=?

if x is directly proportional to y^3 &if (when x=32, y is=2) we can understand that x=4y^3

1,x=4y^3

x=4(6^3)

x=4(216)

x=864

2,x=4y^3

108=4y^3

108/4=4y^3/4

27=y^3

√27=y

y=3

i think it is easy to understand,but if the answers are not clear you can ask me &i hope it helps you

Answer:

A. 90 ft/min

Explanation:

Each minute seems to be going up by 90 minutes (y=90x+0)

This is what it looks like:

(0,0)

(1,90)

(2,180)

(3,270)

(4,360)

(5,450)

And I placed those pints on a graph...

(This is also Linear)

Let's see what to do buddy...

_________________________________ Step (1)

First we must find the measure of x

[tex](3x - 5) + (x + 1) = 180[/tex]

[tex]4x - 4 = 180[/tex]

Both sides plus 4

[tex]4x = 184[/tex]

Divided both sides by 4

[tex]x = \frac{184}{4} \\ [/tex]

[tex]x = 46[/tex]

_________________________________

Step (2)

Now we must find the RQS Angle measure :

Angle ( RQS ) = 46 + 1 = 47

_________________________________

Step (3)

QT bisects RQS ;

So the resulting angles are :

[tex] \frac{47}{2} = 23.5 \\ [/tex]

And we're done.

Thanks for watching buddy good luck.

Answer: the water increases by 2 every hour

Step-by-step explanation:

Answer:2 inches per hour

Step-by-step explanation:

The x axis shows how many hours have passed and the y axis shows how many inches it is so on 1 hr it had 2 inches and on 2 hrs it had 4 inches

Answer:

12x2−4x+3

Step-by-step explanation:

Answer: B

Proof is 7/6 is more than a whole so it’s the greatest while 1/8 is the least then that leaves 2/3 and 9/10 and 9/10 is greater than 2/3 so the answer should be B

Answer:

13(3 - z) = 13(3 - z)

13(3 - z) = 39 - 13z

Step-by-step explanation:

To make the equation have infinitely many solutions, when you simplify, the equation will become z = z

To make this happen, the equation has to be the same on either side of the equal sign. Here are the two options :

13(3 - z) = 13(3 - z)

13(3 - z) = 39 - 13z

Answer:

[tex]y=-3(x+2)^2-3[/tex]

Step-by-step explanation:

Equation of the Quadratic Function

The vertex form of the quadratic function has the following equation:

[tex]y=a(x-h)^2+k[/tex]

Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.

The graph provided in the question, assumed as a parabola, has two clear points:

The vertex, located at (-2,-3)

The point (-1,-6)

Substituting the coordinates of the vertex, the equation of the function is:

[tex]y=a(x-(-2))^2-3[/tex]

[tex]y=a(x+2)^2-3[/tex]

The value of a will be determined by using the other point (-1,-6):

[tex]-6=a(-1+2)^2-3[/tex]

Operating:

[tex]-6=a(1)-3[/tex]

Solving:

a=-3

The equation of the graph is:

[tex]\boxed{y=-3(x+2)^2-3}[/tex]
