Answer:
(-6, 6).
Step-by-step explanation:
The x-coordinate increases by 2 units and the y-coordinate by 9 units:
That is ( - 8 + 2, -3 + 9)
= (-6, 6).
477
The value of the first 7 from the left is 70.
If you divide 70 by 10, you get the value of the second seven, 7.
Another way to know this is equivalent fractions:
1/10 = 7/10
10 X 7 = 70
1 X 7 = 7
Answer:
The surface area of ball is 400π sq.cm
Answer:
.
Step-by-step explanation:
Let 
and 
denote the two endpoints.
The formula for the midpoint of these two points would be:
.
(Similar to taking the average of each coordinate.)
In this question, it is given that 
whereas 
. Substitute these two values into the expression for the coordinate of the midpoint:
-coordinate of the midpoint: 
.
-coordinate of the midpoint: 
.
Solve these two equations for 
and 
: 
whereas 
.
Hence, the coordinate of the other point would be .
The length of he altitude to the hypotenuse is the square root of 108
