Answer:
y=3/2x-5/2
Step-by-step explanation:
1.find the slope
y2-y2/x2-x1
2-(-1)/3-1
2+1/3-1
3/2 slope (m)
2.y-y1=m(x-x1)
y-(-1)=3/2(x-1)
y+1=3/2x-3/2
y=3/2x-3/2-1
y=3/2x-5/2
Formula for the area of a circle is,
pi×radius squared
example,
radius of a circle is 2cm what's the area?use 3.14 as pi
2squared×pi
=2squared×3.14
=12.56cm squared..
hope this helps.....
we know that
the rate of a linear equation is equal to the slope
Step 1
Find the bear’s average heart rate when it’s active
Let
A(1.5,90) B ( 2,120)
the slope is equal to
m=(y2-y1)/(x2-x1)
m=(120-90)/(2-1.5)=30/0.5
m=60 heartbeats/min
therefore
the answer part a) is
the bear’s average heart rate when it’s active is 60 heartbeats/min
Step 2
Find the bear’s average heart rate when it’s hibernating
Let
A(1.5,18) B ( 2,24)
the slope is equal to
m=(y2-y1)/(x2-x1)
m=(24-18)/(2-1.5)=6/0.5
m=12 heartbeats/min
therefore
the answer part b) is
the bear’s average heart rate when it’s hibernating is 12 heartbeats/min
