(0,32)(100,212)
slope = (y2 - y1) / (x2 - x1)
slope(m) = (212 - 32) / (100 - 0) = 180/100 = 9/5 (or 1.8)
so the slope of the line is 9/5...this means that a farenheit degree change is equivalent to a celsius change of 9/5(or 1.8 degrees)
now we find the y int.
y = mx + b
slope(m) = 9/5
(0,32)..x = 0 and y = 32
now we sub and find b, the y int
32 = 9/5(0) + b
32 = b
so ur y int is 32...this means that when celsius temp starts at 0, farenheit temp is 32 degrees

Answer:
t=0
Step-by-step explanation:
r=<+1,>
by differentiating the r vector component by component
r' = <2at, 1>
Two vector are orthogonal when the dot product between them is zero, so:
r'·r=0
<+1,>·<2at, 1>=2+2at+t=0
common factor
t(+2a+1)=0
Then, the only real value for t is zero.
-> t=0
Julian is 24, Kira is 34. The total of both equals 58.
Answer:
the percent of her comic books did Skylar give away is 20%
Step-by-step explanation:
Given that
Skylar has a collection of 60 comic books
She gave away some of her books
And she left by 48 books
we need to find out the percent of the skylar give away books
= (60 - 48) ÷ 60
= 12 books ÷ 60 books
= 20%
Hence, the percent of her comic books did Skylar give away is 20%
