Answer:
y = 2/7x - 40/7
Step-by-step explanation:
y2 - y1 / x2 - x1
-8 - (-4) / -8 - 6
-4/-14
= 2/7
y = 2/7x + b
-4 = 2/7(6) + b
-4 = 12/7 + b
-40/7
It's c because$6.50h = m
h = 4.25
If you're supposed to find the measure of the arc:
The minor arc CD has the same measure as the central angle it subtends. In this case, arc CD has measure 50º. In radians, that's
50º * (π/180 rad/º) = 5π/18 rad
If you instead meant to ask about finding the length of the arc CD, recall that arc lengths and their subtended central angles occur in a fixed ratio equal to the ratio of the circle's total circumference to 2π rad. In other words, if <em>L</em> is the length of the minor arc CD, then
<em>L</em> /(5π/18 rad) = 2π (7 cm) / (2π rad)
==> <em>L</em> = 35π/18 cm
(Notice that arc measure is given radians, while arc length is given in cm, which is why I offer two different answers here.)
Answer:
It should be somewhere near 3.16
Step-by-step explanation:
The square root of 10 simplified is around 3.16
Answer: C, 420
Step-by-step explanation:
The first positive even numbers are from 2 to 40, so the sum is equal to the number of terms, times the number of terms plus one (20*21 = 420)
the sum is 420
