The value of x at equal total cost is 266.67
Here, we want to solve the equation to get the x-value that shows the total costs for the two companies are equal
We proceed as follows;
Answer:
49
Step-by-step explanation:
step 1: Add the ratios 2:7 which is 2+7=9
step 2: divide the bigger ratio (7) by the total calculated in step 1 (9) and multiply by the total number given (63)....
step 3: we have 7/9×63 which is 49
therefore the bigger number is 49
Answer:
i can only see 3
Step-by-step explanation:
Answer:
8.95feet
Step-by-step explanation:
The set up is a right angled triangle where;
The camera's horizontal distance from the focus point = 26feet = Adjacent;
The height of the camera above the floor = Opposite = x
Angle of elevation = 19°
According to TOA in trig identity;
Tan theta = opp/adj
Tan 19 = x/26
x = 26tan 19
x = 26(0.3443)
X = 8.95feet
Hence the camera is placed at a height of 8.95feet above the floor
Answer:
Rate of change 
C per meter.
Step-by-step explanation:
Given,
Then,
Change of temperature at the point say, 
along the direction say, 
is,
![\Big[uT_{x_2}+vT_{y_2}+wT_{z_2}\Big]_{(x,y,z)}](https://tex.z-dn.net/?f=%5CBig%5BuT_%7Bx_2%7D%2BvT_%7By_2%7D%2BwT_%7Bz_2%7D%5CBig%5D_%7B%28x%2Cy%2Cz%29%7D)
=
Hence the rate of change of temperature is C per meter.
