Write the equation in slope intercept form of a line that has a slope of 1/2 and passes through the point (-8,-4).

vagabundo [1.1K]

Slope intercept form is y=mx+b
m(slope)=1/2
(x,y)—->(-8,-4) so x=-8 and y=-4 substitute and solve for b
-4=1/2(-8)+b

-4=-4+b
+4=+4
0=b

A construction worker drops a hammer from a height of 25 m.

Snezhnost [94]

Answer:

Time at which the hammer reaches the ground is 2.3 seconds.

Step-by-step explanation:

We are given the formula as, $h(t)=-4.9t^2+v_{o}+h_{o}$ .

It is known that, when height i.e. $h_{o}=25$ meter, then velocity $v_{o}=0$ m/sec.

So, we get the formula as, $h(t)=-4.9t^2+25$ .

Now, when the hammer hits the ground, the height $h_{o}=0$ meter.

Thus, we have,

$h(t)=-4.9t^2+25$

⇒ $0=-4.9t^2+25$

⇒ $4.9t^2=25$

⇒ $t^2=5.1$

i.e. t= ±2.3 sec

Since, time cannot be negative.

So, t= 2.3 sec

Hence, the time at which the hammer reaches the ground is 2.3 seconds.
