A firework is launched from the ground at a speed of 160 feet per second. It’s height after t seconds is given by the polynomial -16t^2+160t. What is the height of the firework after 4 seconds?

Answers

Answer 1

-16t^2+160t=0
16t^2=160t (Divided by 16)
t^2=10t (Divided by t)
t=10

Height
= Speed x Time
= 160 x 4
= 640 feet

Plss help me, I have to find area

Answers

Answer:

C: 191.

Step-by-step explanation:

The total area of this is a little less than 15 x (3+4+10) = 15 x 17 = 255.

So then we subtract that by 36, which is the rectangle that is missing from the shape. So 255-36 = 219.

So now we have to guess. The triangle seems a little small, so it has to be the largest option, which is C: 191.

can you please help me solve this equation using substitution? I’ve been trying to solve it for so long and can’t do it.

2x-y=5 and 3x+y=-9

Answers

Answer:

x=-4/5 y= -33/5

Step-by-step explanation:

y=-3x-9

2x+3x+9=5

5x=-4

x=-4/5

Then plug it in into an equation.....2(-4/5)-y=5

-8/5-y=25/5

-y=33/5

y=-33/5

You can check if you want

Answer:

x = -4/5, y = -6 3/5

Step-by-step explanation:

The way to use substitution to solve is to isolate (Put it on one side without anything else on that side of the equation) a variable. We can use the first equation to isolate y. We can add y on both sides to get that 2x = y + 5 and then subtract by 5 on both sides to get that y = 2x - 5. Next, we can substitute 2x - 5 in for y in the second equation because y = 2x - 5. We would get that 3x + 2x - 5 = -9, so 5x - 5 = -9, and if you add by 5 on both sides, you get 5x = -4. Finally, we can divide by 5 on both sides to get that x = -4/5. If you want to find y, we can find it by substituting x into the equation 2x - 5 = y. 2 * -4/5 - 5 is equal to y, so -8/5 - 5 = y, and lastly, y = -6 3/5

other person alr did #1, and #2 is 0.175

5% of 3 and one half is 0.175 as a decimal

Answer:

$139.24

Step-by-step explanation:

$98+$20=$118

(1.18)($118)=$139.24

the 1.00 in 1.18 is the cost without tax, the 0.18 is the tax, so if you want the cost of the room with tax you would multiply the cost of the room before tax with 1.18

The tax for every room is the same(.18). Tax is taken from the initial cost so you would do 98+20= 118. $118 is the cost of the double room without tax, $139.24 is with tax.
