First plot the y-intercept.

The equation is in the form: y = mx + b where b is the y-intercept. So when x = 0, y = -5.

(0, -5)

Then choose any other x value to obtain the y value of that coordinate. For example, plug x = 2 in the equation.

y = -1/2x - 5
y = -1/2(2) - 5
y = -6

So a second point can be:

(2, -6)

Plotting these two points should make a linear graph as desired. I attached a picture of where the two points should be as reference.

The function H(t) = −16t2 + 75t + 25 shows the height H(t), in feet, of a baseball after t seconds. Part A: After how many secon

nlexa [21]

Step-by-step explanation:

Given that,

The function that shows the height of a baseball after t seconds is given by :

$H(t)=-16t^2+75t+25$ ....(1)

Part (A).

When the baseball hits the ground,

H(t) = 0

So,

$-16t^2+75t+25=0\\\\t=5\ s\ and\ t=-0.31\ s$

After 5 seconds the baseball will hit the ground.

Pat (B)

For maximum height, put dH/dt = 0

So,

$\dfrac{d}{dt}(-16t^2+75t+25)=0\\\\-32t+75=0\\\\t=2.34\ s$

Put t = 2.34 s in equation (1).

$H(t)=-16(2.34)^2+75(2.34)+25\\\\H(t)=112.89\ m$

Hence, this is the required solution.

A missing fraction on a number line is located exactly halfway between 3/6 and 5/6

Dominik [7]

The missing fraction would be $\frac{4}{6}$ since it is exactly in the halfway between $\frac{3}{6} and \frac{5}{6}$

Answer plz !! Whats the contrapositive ?

Andre45 [30]

Answer:

It should be the first answer.

Step-by-step explanation:

The first answer says "If Nemo is a fish, then he swims". That makes sense. Then the second one says "If Nemo does swim, then he is a fish". That would make sense, but if my name was Nemo, I can swim. That doesn't mean I'm a fish. The the third one says "If Nemo is not a fish, then he doesn't swim". That doesn't make sense. Say my name is Nemo. I'm not a fish. I can swim though!
