Amir stands on a balcony and throws a ball to his dog, who is at ground level. The ball's height (in meters above the ground), x
Y_Kistochka [10]
When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.

0=-(x-2)^{2}+16 \\  \\ 
(x-2)^{2}=16 \\  \\ 
x-2= \sqrt{16} \\  \\ 
x-2=4 \\  \\ 
x=6

This means the ball will hit the ground 6 seconds after Amir threw it

The demand function of blankets at COMESA is given by the equation P=60-2Q find the units of good Q ,when P=12 and use integrati
lions [1.4K]

Answer:

a. 24

b. 864

Step-by-step explanation:

a. The demand function is:

P = 60 - 2Q

When P = 12:

12 = 60 - 2Q

2Q = 60 - 12

2Q = 48

Q = 48/2 = 24

b. Consumer surplus is given as the integral of Demand function:

CS = \int\limits {[P(Q) - (p)(Q)] \ dQ\\

This implies that:

CS = \int\limits {60 - 2Q} \, dQ\\\\CS = 60Q - Q^2\\\\CS = (60 * 24) - 24^2\\\\CS = 1440 - 576\\\\CS = 864

What is the value of x?
Karolina [17]

Answer:

14

Step-by-step explanation:

A triangle with 45 degrees on one corner and 90 degrees on another has 45 degrees on the third corner (180-side1-side2=side3). Therefore that’s an isosceles triangle, which has the same length on the two sides next to the right angle. To get the length of the third side, remember that for any right triangle, the longest side is equal to the square root of :(the first side squared)+(the second side squared). A^2+b^2=c^2 or c=sqrt(a^2+b^2). If you do the math, sqrt((7sqrt2)^2+(7sqrt2)^2)=14. That’s your third side length, x=14.
