Set up a proportion
EA / EB = ED/ EC
16 / (5x + 2 + 16) = 12 / (12 + 24)
16/(5x + 18) = 12 / 36 Cross multiply
16 * 36 = (4x + 18)*12 Remove the brackets
576 = 48x + 216 Subtract 216 from both sides.
360 = 48x Divide by 48
360/48 = x
7.5 = x
Substitute n with 4 to find d(4):
d(4)=d(4-1)+17
d(4)= d(3)+17=47+ 17= 64
Substitute n with 3 to find d(3):
d(3)= d(2)+17=30+17 =47
Substitute n with 2 to find d(2):
d(2)=d(1)+17= 13+17= 30
The 4th term is 64
Your octagon has a central angle of 360 deg. Since you're speaking of an octagon, which implies that the octagon is made up of eight triangles, divide 360 deg by 8 to obtain the measure of each minor arc formed.
Answer:
Step-by-step explanation:
Slope-intercept form: where is the slope and is the y-intercept (the value of y when the line crosses the y-axis)
<u>1) Plug the given slope 5 into the equation</u>
<u>2) Find the y-intercept </u><u> by plugging in the point (-1,-2)</u>
Add 5 to both sides
<u>3) Plug the y-intercept back into the equation</u>
