Answer:
A and C
Step-by-step explanation:
Only A and C represent a 65% increase
Because you are using the format y = mx +c the c value is the y offset.
in this equation the equation can be rewritten as y = 1x -3
Thus the y intercept, the y offset, must be -3.
Hope this helps! :)
Answer:
130.43 cm³
Step-by-step explanation:
To find the difference between the volumes of the balls, we must first find the volumes of the balls. To find the volume of each ball, we must first determine their shape. We understand that both balls are spherical.
The volume V of a sphere wit radius r is given as
V = 4/3 πr³
where r is the result when the diameter of the sphere is divided by 2.
Hence the radius of the Golf ball
= 4.3cm/2
= 2.15cm
radius of the tennis ball
= 6.9cm/2
= 3.45cm
The difference between the volumes of the two balls
= 4/3 π (3.45³ - 2.15³)
= 130.43 cm³
The answer would be 1.0404 because 1.02 multiplied by 1.02 is 1.0404
