Mathematics
1 answer:
Ivanshal [37]3 years ago

Answer:

1.6 Seconds

Step-by-step explanation:

The equation would be h(t)=-16t^2+20t+8 since 20 is the velocity, and once you input that onto a graph the answer of when it hits the ground is 1.569 seconds, so rounded is 1.6 seconds.

No one helped me please please please help please
Softa [21]

Answer: 1/36

Step-by-step explanation:

Calm down, I'm here to help! You might want to watch some videos on how to solve negative powers, but it's simpler than you think.

An exponent expression is formatted as a^b.

If "b", the exponent, is negative, then you can solve expression like this:

1/a^-b

By writing -b, I mean the opposite of b. For example, the opposite of -2 is 2.

Let's use that rule to solve this problem.

1/6^-(-2)

1/6^2

1/6*6

1/36

There you go! It's not too scary now, is it? Let me know if you'd like me to link some resources!

find the missing value so the line passing through the points has the given slope.(10,y) and (3,4);m=3/4
Hoochie [10]

Answer:

The value of y is 9¼.

Explanation:

Given that the slope of the set of points (10,y) and (3,4) is 3/4.

Using the slope formula:

\text{Slope},m=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}}

We have:

\frac{3}{4}=\frac{4-y}{3-10}

We then solve for y:

\begin{gathered} \frac{3}{4}=\frac{4-y}{-7} \\ \text{Cross multiply:} \\ 4(4-y)=-21 \\ 16-4y=-21 \\ -4y=-21-16 \\ -4y=-37 \\ y=\frac{-37}{-4} \\ y=9\frac{1}{4} \end{gathered}

The value of y is 9¼.
