Estimate √53 between two numbers to the tenths place.

1. Identify perfect squares: 72 = 49 and 82 = 64
2. Estimate between two whole numbers: between 7 and 8
3. Determine the closer whole number: closer to 7 because 53 is closer to 49 than to 64
4. Find the squares of tenths: 7.12= 50.41
7.22= 51.84
7.32= 53.29
7.42= 54.76
√53 lies between and

pi x^2

step-by-step explanation:

pi times x squared

don't report but were is the digram

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
