280 square inches because area=bh
1. h₀ = 70
v₀ = 0 since the rock is dropped it has no initial velocity
when the rock hits the ground the height = 0
plug into the formula
0 = -4.9t² + 0(t) + 70
0 = -4.9t² + 70
Add 4.9t² to both sides
4.9t² = 70
Divide both sides by 4.9
t² = 14.2857142857
Take the square root of both sides
t = 3.7796447301
t ≈ 3.8 seconds

Answer:
For #1 the answer is City C
Step-by-step explanation:
To find the value of anything with a sales tax simply multiply the cost by the tax.
$30 * 2.9%
$30 * .029
$0.87
Now that we have the sales tax, add it to the original cost.
$30 + $0.87 = $30.87
You can do this for each of the sales tax problems. Then compare the answers.
Answer:
The distance of point ( 6 , 2 ) from line 6 x - y = 3 is unit .
Step-by-step explanation:
Given as :
The equation of line is 6 x - y = 3
And The points is ( 6 , 2 )
Let The distance between the line and points is d unit
So, The distance of point from the line =
Or, d =
Or, d =
Or, d =
∴ d = unit
Hence The distance of point ( 6 , 2 ) from line 6 x - y = 3 is unit . Answer
