Answer:
(8,150)
Step-by-step explanation:
Polar form is in,
(r,theta).
To find r, apply pythagorean theorem using both coordinates to find r.
To find theta, since we know the opposite and adjacent side, apply the tangent function.
Apply inverse tan function
Since the degrees have to be in between 0 and 360. Add 180 to -30.
So the answer is
(8,150).
You use Pythagorean theorem to solve it and you get 18.3. Just look at the picture to see how i solved it
The first step to solve this problem is to represent
variables for the width and the length:
Let w = width of the rectangle
2w – 1 = length
of the rectangle
The formula to compute for the area of the rectangle is:
A = LW
Substituting the values and variables to the formula:
28 = w (2w – 1)
2w^2 – w = 28
2w^2 – w – 28 = 0
Solve the quadratic equation:
(2w + 7)(w – 4) = 0
w = -7/2 or w = 4
You cannot use the -7/2 because there is no negative
measurement.
W = 4 feet
L = 2(4) – 1 = 7 feet
Therefore the dimension of the rectangle is 4 feet by 7
feet.
Cincinnati Ohio à<span> Charlote North CA = a total of 336 miles
Cincinnati </span>à<span> Chicago Illinois = a total of 247 miles
Perry drove from Charlote to Chicago by passing Cincinati. Find the distance she drove.
=> Note that the distance from charlotte to Cincinnati is 365 then from Cincinnati to Chicago is 247
=> 336 miles + 247 Miles
=> 583 miles
Penny drove for a total of 583 miles from Charlotte to Cincinnati to Chicago.</span>
Answer:
487.5 miles
Step-by-step explanation:
since 1/2 inch represents 75 miles and the distance is 3 1/4 inches you need to mulitply 75 X 6 = 450 and then divide 75/2=37.5 then add the two totals
450 + 37.5 = 487.5 miles
