Pythagoras theorem : a^2 + b^2 = c^2
20^2 + b^2 = 29^2
400 + b^2 = 841
841 - 400 = 441
Square root 441 = 21
PERIMETER :
21+29+20 = 70
The answer is 70
Answer:
p = -0.05m + 22
Step-by-step explanation:
As given in question,
The relation between the price and demand can be given by,
where is p is price and x is demand.
Since in order to sell 300 cards the price has to be fix at $7.
So,
7 = 300m+b <u> </u> (1)
And for every additional card they need to drop the price by $0.05.
So,
7-0.05 = 301m+b
=>6.95 = 301m + b<u> </u> (2)
Subtracting equation (1) from equation (2), we will have
6.95 - 7 = 301m - 300m
=>m = -0.05
By putting the value of m in equation (1), we get
7 = 300.(-0.05)+b
=> b = 22
So, the linear equation that show the relation between price and demand is given by
p = -0.05m + 22
Presumably, the path starts on the horizontal axis at (1, 0) and ends on the vertical axis at (0, 1). Since we know the vector field is the gradient of a scalar function, we can apply the fundamental theorem of calculus (aka gradient theorem):
Answer:
0.84
Step-by-step explanation:
0.84 is 84% of 1, which is a whole number. 0.84/1=84/100
