Every section = (3/4)÷(3) = 1/4 acre
To find H we need to divide 104/13 which is 8 and 13 x 8 = 104.
Hope I helped.
Answer:
a) How much work has he done = dW = 1.3 × 105 J
b) What is the magnitude of the heat that he has lost = dQ = -5.4 × 105 J
Step-by-step explanation:
- From the first law of thermodynamics; dQ = dU + dW
Hence, work done dW = dQ - dU
dW = -6.7 × 105 J - ( -8.0 × 105 J)
dW = 1.3 × 105 J is the work done by the player
- for heat lost; from dQ = dW + dU
- dU = -8.0 × 105 J and dW = 2.6 × 105 J
- heat lost dQ = 2.6 × 105 J + ( -8.0 × 105 J)
- The negative is as a result of heat lost by the player
Answer:
H(x) = 0.85x -2.00
Step-by-step explanation:
The original price of an item, x dollars, is discounted by 15%.
Let x be the original price of an item
15% =0.15 discount , so discounted amount is 0.15x
Now we subtract discounted amount from original amount
x - 0.15x = 0.85x
A coupon for $2.00 off is applied to the discounted price.
$2.00 is off, so we subtract 2
Function becomes H(x) = 0.85x -2.00
The coordinates of centroid are: (10/3, 3)
Step-by-step explanation:
The formula for calculating centroid of a triangle is:
Here (x1,y1) are the coordinates of first vertex
(x2,y2) are the coordinates of second vertex
(x3,y3) are the coordinates of third vertex
Given:
G(-2,5) = (x1,y1)
H(6,5) =(x2,y2)
J(6,-1) = (x3,y3)
Let I be the centroid of the triangle
Putting the values in the formula
The coordinates of centroid are: (10/3, 3)
