Answer:
$696.70
Step-by-step explanation:
The formula for the area of a circle is given as πr²
From the above question
π = 3.14
Diameter = 5 feet
Radius = Diameter/2 = 5 feet/2 = 2.5 feet
Hence,
The area of the circular table = 3.14 × 2.5²
= 19.625 ft² or 19.625 square foot
We are told that:
The wood costs $35.50 per square foot
Hence,
1 ft² = $35.50
19.625 ft² = x
Cross Multiply
x = 19.625 ft² × 35.50
x = $696.6875
Approximately = $696.70
Therefore, it will cost Rafael $696.70 to make the table.
Let x be the distance (in feet) along the road that the car has traveled and h be the distance (in feet) between the car
and the observer.
(a) Before the car passes the observer, we have dh/dt < 0; after it passes, we have dh/dt > 0. So at the instant it passes the observer we have
dh/dt = 0, given that dh/dt varies continuously since the car travels at a constant velocity.
The line graph is unsuitable for her purposes because it does not show adequately the comparison of the expenses.
Line graph is used to show the increase/decrease of a particular variable.
Bar graph is a more adequate format to create a visual representation.
Answer:
Step-by-step explanation:
According to given condition
Answer:
Step-by-step explanation:
Parallel lines share the same slope.
In the given 4x - 2y = 4, the first 4 (the coefficient of x) and the -2 (the coefficient of y) determine the slope; all lines parallel to 4x - 2y = 4 have equations which are identical to 4x - 2y = 4 EXCEPT that their constants (in this case 4) differ.
4x - 2y = 0
4x - 2y = -3
4x - 2y = 7
constitute a set of parallel lines.
If we reduce 4x - 2y = 4 to 2x - y = 2, the second equation has the same slope AND same y-intercept as does the first.
