The points A(12,7), B(12,−3), C(−2,−3), and D(−2,7) form rectangle ABCD. Which point is halfway between A and B? CLEAR CHECK (12
Flura [38]
We have that
coordinates  are
<span>A(12,7), B(12,−3), C(−2,−3), and D(−2,7) 
</span>
i use the formula of midpoint <span>between A and B
</span>Xm=(x1+x2)/2    Ym=(y1+y2)/2
A(12,7) B(12,−3)
Xm=(12+12)/2=12
Ym=(7+(-3))/2=2

the point  (12,2)   <span>is halfway between A and B</span>

ollegr [7]

Answer:

6

Step-by-step explanation:

GIVEN: The weight, in pounds, of a newborn baby t months after birth can be modeled by the function W(t)=1.25t+6.

TO FIND: What is the y-intercept of the function and what is its interpretation in the context of the problem.

SOLUTION:

in  W(t)=1.25t+6

if t=0

W(0)=6

Hence y-intercept is 6

the y-intercept in this represents the weight of baby just after he is born.

Vega swam her leg of the race in 27.98 seconds and Janice swam her leg of the relay race in 25.679 seconds. What was their combi
morpeh [17]

To get their combined time, get the sum of Vega's time and Janice's

27.98\text{ sec}+25.679\text{ sec }=53.659\text{ sec}

Therefore, their combined time for their part of the relay is 53.659 seconds.

A circle has a radius that is 4 centimeters long. If a central angle has a measure of 3 radians, what is the length of the arc t
kirill115 [55]
The total length of the circle is calculated by the following formula:

Lenght = 2.π.r

As r = 4c

Then,

Lenght = 2.π.4

Lenght = 8π centimetrs

Now use the rule of 3


But we have to know:

...<..> ...

Then,

8π ________ 2π <= 360°

x ________ 3π


2π . x = 8π . 3π

x = (8π . 3π) / 2π

x = (8 . 3π)/ 2

x = 12π centimenters

x ~ 37,69 c
