Answer:
<h3>d. 1, 2, 4, 8, 16, 32</h3>
Step-by-step explanation:
Pascal's triangle is the a triangular array of binomials coefficient of equations of each degree.
<h3>n=0 1 </h3><h3>n=1 1 1</h3><h3>n=2 1 2 1</h3><h3>n=3 1 3 3 1</h3><h3>n=4 1 4 6 4 1</h3><h3>n=5 1 5 10 10 5 1</h3><h3 />
An easy way to list Pacsal's triangles is the number below Two numbers is the sum of those two numbers.
for example look at the number 10 at the triangle it is actually the sum of Two numbers above it 6 and 4
after listing pascals triangle we can calculate sum as 1,2,4,8,16,32
<u>Method 2</u>
Sum of numbers in nth row is
so sums are ,,,,,
or, 1,2,4,8,16,32

Solve the inequality that represents the story. Then interpret what the solution means in the story.
Lin buys a candle that is 9 inches tall and burns down x inches per minute. She wants to let the candle burn for 7 minutes until it is less than 6 inches tall.
9 - 7x < 6
Answer:
x > 3/7
x which is the inches per minute the candle will burn should be greater than 3/7 for the candle to be less than 6 inches tall.
Step-by-step explanation:
The candle is 9 inches and it burns down x inches per minute. Lin wants to let the candle burn for 7 minutes until it is less than 6 inches tall. The inequality can be solved below.
9 - 7x < 6
subtract 9 from both sides of the equation
9 - 9 - 7x < 6 - 9
- 7x < - 3
divide both sides by -7
- 7x / -7 < - 3/ - 7
dividing both sides with a negative values changes the inequality sign
x > 3/7
x which is the inches per minute the candle will burn should be greater than 3/7 for the candle to be less than 6 inches tall.
Answer:
1st option: -2 < x ≤ 3
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We see that our x-values span from -2 to 3. Since -2 is an open dot, we cannot include it in our domain:
(-2, 3] or -2 < x ≤ 3
Answer:
3 1/2 hours
Step-by-step explanation:
time = distance/speed
440/110 = 4 hours
440/880 = 1/2 hours
4 minus 1/2 is 3 1/2
