Answer:

Step-by-step explanation:

The equation for projectile motion in feet is [tex]h(t)=-16t^2+v_0t+h_0[/tex] where [tex]v_0[/tex] is the initial velocity in ft/s and [tex]h_0[/tex] is the initial height in feet.

We are given that the initial upward velocity is [tex]v_0=150ft/sec[/tex] and the initial height is [tex]h_0=35ft[/tex]. Thus, plugging these values into our equation, we get [tex]h(t)=-16t^2+150t+35[/tex] as our equation for the situation.

The firework will land, assuming it doesn't explode, when [tex]h(t)=0[/tex], thus:

[tex]h(t)=-16t^2+150t+35\\\\0=-16t^2+150t+35\\\\t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\ \\t=\frac{-150\pm\sqrt{150^2-4(-16)(35)}}{2(-16)}\\ \\t=\frac{-150\pm\sqrt{22500+2240}}{-32}\\\\t=\frac{-150\pm\sqrt{24740}}{-32}\\\\t=\frac{-150\pm2\sqrt{6185}}{-32}\\ \\t=\frac{75\pm\sqrt{6185}}{16}\\\\t_1\approx-0.2\\\\t_2\approx9.6[/tex]

Since time can't be negative, then the firework will land after 9.6 seconds, assuming it doesn't explode at the time of landing.

Step-by-step explanation:

Answer:

24

Step-by-step explanation:

The formula for calculating the sum of interior angles is:

(n - 2) x 180°  (where n is the number of sides)

interior angle of a polygon = sum of interior angles ÷ number of sides

165 = [ (n - 2) x 180° ] ÷ n

Mulitply both sides by n:             165n = (n - 2) x 180°

Expand brackets:                         165n = 180n - 360

Add 360 to both sides:    165n + 360 = 180n

Subtract 165n from both sides:   360 = 15n

Divide both sides by 15:                 24 = n

Therefore, the number of sides = 24

Answer:

x=5

Step-by-step explanation:

First we will rewrite 81=3^4

Now we have that our equation is in form of

3^4=3^x-1

From this we have that

4=x-1

We can conclude that:

x=5

Answer:

c because I did this one an yeah

The value of k is -11.

Given

The equation 3√(x-k)-2=10 has a solution of x = 5.

To find the value of k put x = 5 in the equation then solve for the value of k.

Therefore,

The value of k is;

[tex]\rm 3\sqrt{x-k}-2=10[/tex]

Substitute x = 5 in the equation

[tex]\rm 3\sqrt{5-k}-2=10\\\\\rm 3\sqrt{5-k}=10+2\\\\\rm 3\sqrt{5-k}=12\\\\\rm \sqrt{5-k}=\dfrac{12}{3}\\\\ \sqrt{5-k}=4\\\\[/tex]

Squaring on both sides

[tex]\rm \sqrt{5-k}=\dfrac{12}{3}\\\\5-k=16\\\\-k = 16-5\\\\-k=11\\\\k=-11[/tex]

Hence, the value of k is -11.

Step-by-step explanation:

solve the equation 4x + 6 = 4 + 2(2x + 1). Which choice describes the meaning of his result, 6 = 6?

4x + 6 = 4 + 2(2x + 1)

4x + 6 = 4 + 4x + 2

6 = 4 + 2

6 = 6

Answer:

x=2.1

Step-by-step explanation:

collect like terms 2.4x+5.8x=8.2x

move the terms to the left side and change its sign to -8.2x

move the constant(-3.28) to the right and change its sign to 3.28

equation should now be 9x-8.2x=-1.6+3.28

next you're going to do 9x-8.2x=0.8x

then -1.6+3.28=1.68

divide both sides of the equation by 0.8

x=2.1 is your final answer

Answer:

Step-by-step explanation: Let's say you have 2 supplementary angles, x and y

So x + y = 180

if x is 79.6 degrees less than the measure of a supplementary angle, then x = y - 79.6

Putting this into our x + y = 180 equation, we get

(y - 79.6) + y = 180

2y - 79.6 = 180

2y = 180 + 79.6

2y = 259.6

y = 259.6/2 = 129.8 degrees.

so x = 129.8 - 79.6 = 50.2 degrees.

See if it worked. x = 129.8 degrees,  y = 50.2 degrees,    x + y = 180 so we found the correct two angles!

Answer: Choice A

[tex]\angle F \text{ and } \angle R[/tex]

========================================

Explanation:

The order of the lettering of GFHE and TRQS is important.

This is because the letters of each pair up together

Because the figures are similar, the paired angles are congruent. So we can say [tex]\angle F \cong \angle R[/tex]

In terms of a visual confirmation, angles F and R are located in the bottom left corner. So this helps back up the answer. Though keep in mind that often the diagrams are misleading and not drawn to scale. So we can't always rely solely on the diagram.

Answer:

The distance each bus travels is given as d=tr where

- d is distance bus travels

- t is a time bus travels

- r is the speed of the bus

:

Distance first bus travels for 4 hours is d1=4r.

Distance other bus travels for 4 hours is d2=4(r+12).

:

The total distance between them is 480 miles and since they go in opposite directions this distance is the sum of distances each bus travels.

:

d1+d2=480

4r+4(r+12)=480

4r+4r+48=480

8r+48=480

8r=432

r=432/8

r=54 mph, this is a speed of the first bus

:

r+12=66 mph, this is the speed of the second bus
