Answer: D

Step-by-step explanation:

The slopes of two perpendicular lines are negative reciprocals of each other

The slope of this line is -1/4, the reciprocal is just the flipped fraction which is -4/1 or 4. Since it is a negative reciprocal you multiply it by -1. 2 negatives multiplied equals a positive so the slope of the perpendicular line is 4

y=mx + c ....(1)general line eqn)

y=-(1/4x) - 9 .....(2)

Comparing (1) and (2)

m=-1/4

Since both lines are

perpendicular

M=-1/m

Where M=gradient of other line

M=-1/(-1/4)

= -1 x - 4/1

=4
Therefore the gradient of the

other line is 4

What is the diameter of a sphere with a volume of 498 in3, to the nearest tenth of an inch

Romashka-Z-Leto [24]

Answer:

9.8 inches

Step-by-step explanation:

<h3>Formula for volume of the sphere is = 4/3πr³</h3><h3>Form and solve the equation for the radius</h3><h3>So: 4/3πr³= 498in³</h3><h3>πr³= 498in³*3/4 which = to 373.5in³</h3><h3>r³= 373.5in³/π</h3><h3>r=∛(373.5in³/π)</h3><h3>calculate r and times the result by 2 for diameter</h3><h3>it will be 9.834...</h3><h3>nearest tenth of an inch means the accuracy is 1 decimal place because nearest tenth= 1/10 or 0.1</h3><h3>So the final answer is 9.8in</h3>
