The geometric mean (GM) of two numbers is the square root of their product:
GM = √(9 × 25)
GM = √225
GM = 15
To find 62% of 62, multiply: (62 × 62) ÷ 100 = 38.44
To round 95 to the nearest 10, look at the units digit (5).
Since it's 5 or more, round up → 95 → 100.
(x, y) is equidistant from (0, 1) and (3, 3).
Distance formula gives 6x + 4y = 17.
Check (1.5, 2): 6(1.5) + 4(2) = 9 + 8 = 17.
So, (1.5, 2) is the point.
To increase 76 in the ratio 5:2, we need to multiply 76 by 5/2.
New value = 76 × 5/2
= 76 × 2.5
= 190
1 centimeter = 10 millimeters
So, 7.2 cm × 10 = 72 mm
The number of subsets of a set with n elements is 2^n.
Here, X has 5 elements.
Number of subsets = 2^5
= 32
Use identity: tan θ + sec θ = (sin θ/cos θ) + (1/cos θ) = (sin θ + 1)/cos θ
Therefore, tan θ + sec θ = (1 + sin θ)/cos θ.
