Answer:
y=1/2x-6
Step-by-step explanation:
y-y1=m(x-x1)
y-(-1)=1/2(x-10)
y+1=1/2x-10/2
y=1/2x-5-1
y=1/2x-6
The equivalent expression is option A) 12(l+2a)
<u>Step-by-step explanation</u>:
- The expression for total cost = 12l+24a
- Taking 12 as common from all the terms in the expression,
we get, 12 (l+2a)
Therefore, The equivalent expression of 12l+24a is 12(l+2a).
1 over 5a to the 2nd power
Answer:
Option C. 
Step-by-step explanation:
we know that
The volume of a sphere is equal to
we have
substitute
Answer: 1860480
Step-by-step explanation:
Initially, there are 20 balls where 5 must be chosen in order.
The number of possible outcomes may be calculated using the concept of permutations.
The formula for permutations is:
nPr =n!/(n−r)!
where n represents the number of items and r represents the number of items to be selected.
The number of ways of selecting 5 balls in order out of 20 is:
20P5 = 20!/15!
= 1860480
To conclude, there are 1860480 possible outcomes.
