Answer:

h(t) = 4.68 seconds

Step-by-step explanation:

The function that represents the height of each firework in feet is :

[tex]h (t) = -16t^2 + 150t + 10.5[/tex] .....(1)

We need to find the time the fireworks take to reach their maximum height. For maximum height,

dh/dt = 0

So,

[tex]\dfrac{d}{dt}(-16t^2 + 150t + 10.5 )=0\\\\-32t+150=0\\\\t=\dfrac{150}{32}\\\\t=4.68\ s[/tex]

Put t = 4.68 in equation (1).

[tex]h (t) = -16(4.68)^2 + 150(4.68)+ 10.5\\\\h(t)=362.06\ text{feet}[/tex]

So, the fireworks will take 4.68 seconds to their maximum height.

Answer:

[tex]h = 12[/tex]

[tex]x = 9[/tex]

[tex]y= 16[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Find h, x and y

Let the base of the triangle be 15.

So, the area is:

[tex]A = \frac{1}{2} * 15 * 20[/tex]

[tex]i.e\ height = 20[/tex]

[tex]A = \frac{1}{2} * 300[/tex]

[tex]A = 150[/tex]

Let the base of the triangle be 25.

So, the area is:

[tex]A = \frac{1}{2} * 25 * h[/tex]

[tex]i.e\ height = h[/tex]

[tex]A = \frac{1}{2} * 25h[/tex]

Substitute [tex]A = 150[/tex]

[tex]\frac{1}{2}*25h = 150[/tex]

Solve for h

[tex]h = \frac{150 *2}{25}[/tex]

[tex]h = 6 *2[/tex]

[tex]h = 12[/tex]

Considering the smallest triangle

[tex]Hypotenuse = 15[/tex]

So:

[tex]15^2 = h^2 + x^2[/tex]

[tex]15^2 = 12^2 + x^2[/tex]

This gives:

[tex]15^2 - 12^2 = x^2[/tex]

[tex]81 = x^2[/tex]

Take square roots

[tex]9 =x[/tex]

[tex]x = 9[/tex]

Solving for y

[tex]x + y = 25[/tex]

[tex]y= 25 - x[/tex]

[tex]y= 25 - 9[/tex]

[tex]y= 16[/tex]

Answer:

Step-by-step explanation:

The equation of line is y = 3x + 9 , where the slope is m = 3

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

y = 3x + 9   be equation (1)

The equation is of the form y = mx + b where m is the slope and b is the y-intercept

Substituting the values in the equation , we get

Slope m = 3

The y intercept of the line is ( 0 , 9 )

Now , the equation of line is plotted on the graph below

Hence , the equation of line is y = 3x + 9

Answer:

Step-by-step explanation:

Answer:

D. 6g

Step-by-step explanation:

The problem says we have a square flower bed to start out with.

Let's have the sides of the squares be "x". The area of this original flower bed is [tex]x^{2}[/tex].

Then, one side of the square is enlarged by 2ft, and another side 3ft. Our new flower bed dimensions are now (x+2) and (x+3). Multiply (x+2) and (x+3) to find the area, which gets you [tex]5x^{2} +6x+6[/tex].

We also know that the new area of the flower bed is twice the size of the original flower bed. Multiply the original area by 2, you get [tex]2x^{2}[/tex].

With the new area and the doubled original area, we can now make an equation: [tex]5x^{2} +6x+6=2x^{2}[/tex]

Solve for x,  you get 6.

Hope this explanation helped, maybe a bit too many details but there's your answer, 6!

The side length of the original bed is 6 units

The formula for finding the area of the square is expressed as:

A = x^2

If one side of a square flower bed was enlarged by 2 ft and the other side was enlarged by 3 ft, the area of the bed becomes;

A = (x+2)(x+3)

A = x^2 + 5x + 6

If the area of a new flower bed became twice the area of an old one, then;

5x^2 + 6x + 6 = 2x^2

On factorizing, the value of x is 6 which shows that the side length of the original bed is 6 units
