We are given a concave spherical mirror with the following dimensions:
Radius = 60 cm; D o = 30 cm
Height = 6 cm; h o = 6 cm
First, we need to know the focal length, f, of the object (this should be given). Then we can use the following formulas for calculation:
Assume f = 10 cm
1/ f = 1 /d o + 1 / d i
1 / 10 = 1 / 30 + 1 / d i
d i = 15 cm
Then, calculate for h i:
h i / h o = - d i / d o
h i / 6 = - 15 / 30
h i = - 3 cm
Therefore, the distance of the object from the mirror is 3 centimeters. The negative sign means it is "inverted".

Answer:
The total price of the Rice sack is Rs 1920.
Step-by-step explanation:
The price of 1 sack of rice = Rs. 1,850
Wages Charge = Rs. 70
Now, the total price = Price of the Rice + Wages Charge
= Rs. 1,850 + Rs. 70
= Rs. 1920
or, the total price = Rs. 1920
Hence, the total price of the Rice sack is Rs 1920.
Answer:
y = -4x - 6
Step-by-step explanation:
12x + 3y = -18
Solve for y.
3y = -12x - 18
y = -12/3 x - 18/3
y = -4x - 6
