yes it is correct
with parentheses you have to bring EVERYTHING INSIDE THE PARENTHESES to the given power but not if there are no parentheses
Answer:
7.21
Step-by-step explanation:
Given that:
P1=(-1,3) and P2=(5,-1)
Distance between two points :
d = Sqrt[(x2 - x1)² + (y2 - y1)²]
x1 = - 1 ; y1 = 3
x2 = 5 ; y2 = - 1
d = Sqrt[(5 - (-1))² + ((-1) - 3)²]
d = Sqrt[(5 + 1)² + (-1 - 3)²]
d = sqrt[(6)^2 + (-4)^2]
d = sqrt(36 + 16)
d = sqrt(52)
d = 7.21
Answer:
20 TV need to be sold to qualify for the trip.
Step-by-step explanation:
Given: Sale price of each TV is $250
Sales target to qualify for trip is $5000.
As given, T represent TV sold.
Now, finding the number of TV sold to qualify for the trip.
Forming an inequality for the number of TV sold to qualify for trip.
We know, Total amount of TV sold= 
∴ To qualify for trip: 
solving it by dividing both side by 250
∴

Hence, Angelica need to sell minimum 20 TV to qualify for the trip.
{7, 8, 9, 10} {9, 10, 11, 12} Which of the following shows the intersection of the sets? A. {9, 10} B. {7, 8, 9, 10} C. {9, 10,

Answer:
<h3>
{ 9 , 10 }</h3>
Option A is the correct option.
Step-by-step explanation:
Let the sets be A and B
A = { 7 , 8 , 9 , 10 }
B = { 9 , 10 , 11 , 12 }
<u>The intersection of sets A and B is </u><u>the</u><u> </u><u>set</u><u> </u><u>of</u><u> </u><u>all</u><u> </u><u>ements</u><u> </u><u>which</u><u> </u><u>belongs</u><u> </u><u>to</u><u> </u><u>both</u><u> </u><u>A</u><u> </u><u>and</u><u> </u><u>B</u><u>.</u>
The intersection of sets A and N is denoted by ( A ∩ B ) and read as A intersection B.
A ∩ B = { 7 , 8 , 9 , 10 } { 9 , 10 , 11 , 11 , 12 }
Now, list the elements which are present in both sets. A ∩ B = { 9 , 10 }
Hope I helped!
Best regards!
