Answer:
No, it is NOT a function.
Step-by-step explanation:
A functions' inputs are assigned to exactly one output.
We are given the points:
{(8,2) (4,-3) (6,4) (8,1)}
The input of 8 is repeating.
The given relation is not a function.
Hope this helps!
Answer:
1,890 feet
Step-by-step explanation:
2 inches=30 feet
4.2 inches= 63 feet
63ft x 30 ft= 1,890ft
Answer:
the surface area is 133cm.
7 x 7 is 49
7 x 6 is 42.
42 divided by 2 is 21.
21 x 4 is 84
So 84 + 49 is 133.
Answer:
88 
Step-by-step explanation:
Given 3 measurements 6,11,4
Assuming them to be length, width and height of pyramid
⇒
Length= 6 cm
Width= 11cm
Height= 4 cm
⇒
Therefore Volume of Given Pyramid
=
⇒Volume of pyramid=88
Answer:
3.2 miles
Step-by-step explanation:
Given that Mary drives 9 miles north and 6 miles east to get there, the resultant miles will be achieved by using pythagorean theorem
R = sqrt ( 9^2 + 6^2 )
R = sqrt ( 81 + 36 )
R = sqrt ( 117 )
R = 10.82 miles
while Ben drives 3 miles south and 7 miles west
Use the same pythagorean theorem to find the resultant displacement
R = sqrt ( 3^2 + 7^2 )
R = sqrt ( 9 + 49 )
R = sqrt ( 58 )
R = 7.62 miles
The difference in miles to where Mary and Benjamin live will be difference in the resultant displacement of the two
Difference = 10.82 - 7.62 = 3.2 miles.
Therefore, Mary live 3.2 miles from Benjamin.
