Answer:
sample answer: If you make a table of values, you can see that 4 quarters equal 1 dollar and 8 quarters equal 2 dollars. If you graph the data, you will see a straight line. Therefore, this situation represents a linear function with a constant rate of change of 1/4
Step-by-step explanation:
Answer:
6, 5
Step-by-step explanation:
-3 + 9 = 6
15-10 = 5
<span>Polygon ABCD is a parallelogram
m<ABC = m<ADC = 127
360 - 2(127) = 360 - 254 = 106
m<BCD = m<BAD = 106/2 = 53
</span>P = 2(10 + 5) = 2(15) = 30
answer
<span>The perimeter of the parallelogram is 30 units, and </span>m<BCD is 53°
Answer:
i) 60°
ii) 14.7 cm
Step-by-step explanation:
length of Arc BA = 8.4 cm
length of radius = 8 cm
angle AOC = 45°
BO = AO = CO = 8 cm
<u>i) What is the measure of Angle BOA </u>
= length of Arc BA / Radius
= 8.4 / 8 = 1.05 radians = 60.16° ≈ 60°
<u>ii) what is the length of arc BAC</u>
= radius * angle BAC * 
angle BAC = angle AOC + angle BOA
= 45° + 60° = 105°
hence length of arc BAC
= 8 * 105 * 
≈ 14.7 cm
