Answer:

see the attachment for the graph

Step-by-step explanation:

The radius can be computed from the distance formula:

d = √((x2-x1)^2 +(y2-y1)^2)

d = √((7-5)^2 +(2-5)^2) = √(4+9) = √13

d ≈ 3.6056

The radius of the circle is √13, about 3.6056 units.

A model rocket is launched with an initial upward velocity of 138 ft/s. The rocket's height h (in feet) after 1 seconds is given
insens350 [35]

Answer:

t = 8.017 or 0.608 (nearest hundredth)

Step-by-step explanation:

h = 138t-16t^2

when h = 78:

\implies 138t-16t^2=78

\implies 16t^2-138t+78=0

Using quadratic formula:

t=\dfrac{138 \pm\sqrt{(-138)^2-(4 \cdot 16 \cdot 78)} }{2 \cdot 16}

\implies t=\dfrac{138 \pm\sqrt{14052} }{32}

\implies t=8.017, t = 0.608

What is the slope of a line is parallel to y=(1/2)x=3
aniked [119]
Hi there! The answer is (1/2)

I suppose you mean the slope of a line that is parallel to y = (1/2)x + 3.

This equation is written in slope-intercept form, which means that the number in front of x represents the slope of the line. The other number represents the y-intercept.

A line that is parallel to another line, will be a line with the same slope. Since the slope of y = (1/2)x + 3 is (1/2), the slope of a line parallel to this line is (1/2) as well.

~ Hope this helps you!
