Estimate the square root. Round to the nearest integer. V56

1 answer:

5 0

The 2 square numbers closest to 56 are 49(7x7) and 64 (8x8)

So the square root is somewhere between 7 and 8

56 is 7 away from 49 and 8 away from 64 so we know the number will round to 7 but be fairly close to 7.5.

A good estimation would be 7.4

It’s asking you to round to the nearest integer (no decimals) so this would be 7

Because square roots are both positive and negative and it’s asking for it as an integer (includes negative numbers), the answers is +7 or -7. Both are the correct answer

B = 2 · A/h
b = 2 / 1 x 90 / 5 5/8 top times top, bottom times bottom (2 x 90, 1 x 5 5/8)

Answer:

cscθ = 5/4, secθ = 5/3

Step-by-step explanation:

First, let's view the drawing that I have attached, with the dot in the bottom left representing the origin. We know that cosecant and secant are the reciprocals of sin and cos respectively, and in order to find sin and cos, we must find the opposite, adjacent, and hypotenuse sides. The hypotenuse is opposite the right angle, equal to √(8²+6²) = 10

Next, we can find sin and cos of θ . sinθ = 8/10=4/5, making cscθ the reciprocal of 4/5, or 5/4

Similarly, cosθ = 6/10=3/5, and secθ = 5/3
