Where is the diagram... I don't see it
Answer:
b = 81
Step-by-step explanation:
given a² and b are directly proportional then the equation relating them is
a² = kb ← k is the constant of proportionality
to find k use the condition a = 2 when b = 9 , then
2² = 9k
4 = 9k ( divide both sides by 9 )
= k
a² =
b ← equation of proportion
when a = 6 , then
6² =
b
36 =
b ( multiply both sides by 9 to clear the fraction )
324 = 4b ( divide both sides by 4 )
81 = b
Answer:
170.3 miles per hour
Step-by-step explanation:
Javon won Indianapolis 500 race in 2011 with an average speed of 170.265 miles per hour. What was his average speed to the nearest tenth of a mile per hour?
From the above question, we are asked to approximate to the nearest tenth of a mile.
The number that falls under the tenth of a mile, is the number that is immediately after the decimal.
Hence, for:
170.265 miles per hour:
2 is the number in the tenth place, the number after 2 is 6, it is a number that is higher than 5. So we add 1 to 2
Therefore,
170.265 miles per hour to the nearest tenth of a mile = 170.3 miles per hour.

Answer:
The line has a slope of zero which means the line is a horizontal line.
Step-by-step explanation:
Given that:
The two points are (-3,2) and (4,2)
Slope of a line is given by the formula,

Here,

Putting these values in formula;

Hence,
The line has a slope of zero which means the line is a horizontal line.
