The object will hit the ground after 5 seconds. You can rewrite the quadratic function as a quadratic equation set equal to zero

to find the zeros of the function 0 = –16t2 + 80t + 0. You can factor or use the quadratic formula to get t = 0 and t = 5. Therefore, it is on the ground at t = 0 (time of launch) and then hits the ground at t = 5 seconds

Answer:

math has:30

game has:26

Step-by-step explanation:

math⇒x

game⇒y

x+y=56

x=y+4

so y+4+y=56 ⇒2y+4=56

⇒56-4 ⇒2y=52⇒y=52/2⇒26

and if y = 26 then x=30

I’ve posted this a lot already and i keep getting it wrong can you help pls?
Schach [20]

Answer: See below; x=1/6

Step-by-step explanation:

This problem may seem intimidating, but all you need to know are your exponent rules. Let's first work inside the parenthesis. Since the bases are the same, we can directly subtract the exponents.

\frac{3}{4} -\frac{3}{8}                             [common denominator]

\frac{6}{8} -\frac{3}{8}                             [subtract]

\frac{3}{8}

Now, our new answer is (3^\frac{3}{8} )^\frac{4}{9}.

Unfortunately, the answer is asking for an exponent with a single base. One of the properties is when the exponents are separated by parenthesis, you multiply them together.

\frac{3}{8} *\frac{4}{9}                              [cross cancel to simplify]

\frac{1}{2} *\frac{1}{3}                              [multiply]        

\frac{1}{6}

Our final answer is 3^\frac{1}{6}.

The value is x is \frac{1}{6} since 3^\frac{1}{6} is equal to 3^x, we know that x=\frac{1}{6}.

2y+8×=2 identify the table that would correctly graph this equation
lys-0071 [83]

We have

2y+8x=2

In order to obtain easily the table, we need to clear y

\begin{gathered} 2y=-8x+2 \\ y=\frac{-8x+2}{2} \\ y=-4x+1 \end{gathered}

then we evaluate for values of x

if x=0

y=-4(0)+1=1

y=1

if x=1

y=-4(1)+1=-3

y=3

if x=2

y=-4(2)+1=-7

y=-7

if x=3

y=-4(3)+1=-11

y=-11

So the table for the given equation is

x y

0 1

1 -3

2 -7

3 -11
