Answer:
I think option B i.e. when its angles are right angles.
The average rate of change is given by [f(b) - f(a)]/(b - a), where a and b represent the interval [a, b].
Let a = -2
Let b = -1
[(-1)^2 + 10 - ((-2)^2 + 10)]/(-1 -(-2))
[1 + 10 - (4 + 10)]/(-1 + 2)
[1 + 10 -4 -10]/(1)
[1 - 4]/(1)
-3/1
Answer: -3
Answer: 36
Step-by-step explanation:
One roll is of length = 9 feet
1 foot = 12 inches
9 feet = 12 *9 = 108 inches
Since there are 5 rolls
So, total length of 5 rolls = 108 * 5 = 540 inches
Since we are given that A seamstress needs to cut 15-inch pieces of ribbon from a roll of ribbon that is 9 feet in length.
We are supposed to find . What is the greatest number of 15-inch pieces the seamstress can cut from 5 of these rolls of ribbon
So, number of 15-inch pieces the seamstress can cut from 5 of these rolls of ribbon:
Hence the greatest number of 15-inch pieces the seamstress can cut from 5 of these rolls of ribbon is 36
we are given that
angle(ACF)=90
angle(ACB)=61
sum of all angles along any line is 180
so, we get
angle(ACF)+angle(ACD)=180
we can plug value
90+angle(ACD)=180
angle(ACD)=90
now, we can use formula
angle(ACD)=angle(ACB)+angle(BCD)
now, we can plug values
and we get
90=61+angle(BCD)
90-61=61-61+angle(BCD)
angle(BCD)=29................Answer
