The distance between the points is the hypotenuse (c). One of the lengths is a and the other is b (it doesn't matter which). Count the number of square for the two sides, square each number, add them then square root them. That is c. 

For the 1st one:
6^2 + 8^2 =c^2
36 + 64 = c^2
100 = c^2
10 = c

mr_godi [17]

Answer:

12 days

Step-by-step explanation:

Total gallons of the family's drinking water needs = gallons consumed by children + gallons consumed by adults

3\frac{1}{2} + 1\frac{3}{4} =

Converting to decimals

3.5 + 1.75 = 5.25 = 5\frac{1}{4}

If there are 63 gallons, the water supply would last for :

63 / 5.25 =12 days

Simplify the expression. Quantity cosecant of x to the power of two times secant of x to the power of two divided by quantity se
Art [367]

Answer:

D. 1

Step-by-step explanation:

We have the expression, \frac{\csc^{2}x\sec^{2}x}{\sec^{2}x+\csc^{2}x}

We get, eliminating the cosecant function,

\frac{\sec^{2}x}{\frac{\sec^{2}x}{\csc^{2}x}+1}

As, sinx is reciprocal of cosecx and cosx is reciprocal of secx,

i.e. \frac{\sec^{2}x}{\frac{\sin^{2}x}{\cos^{2}x}+1}

i.e. \frac{1}{\cos^{2}x}\times \frac{\cos^{2}x}{\sin^{2}x+\cos^{2}x}

Since, we know that, \sin^{2}x+\cos^{2}x=1

Thus,

\frac{1}{\cos^{2}x}\times \frac{\cos^{2}x}{\sin^{2}x+\cos^{2}x}=1

So, after simplifying, we get that the result is 1.

Hence, option D is correct.
