Give the algebraic expression by using variables and constant and arithmetic operations: i. Sum of the squares of x and y. ii.Pr

Olenka [21]

Answer:

a) x^2 + y^2

b) 9-xy

Step-by-step explanation:

Here, we want to write the algebraic statements as expressions;

a) The sum of the squares of x and y

The square of x is x^2

The square of y is y^2

The sum of the squares is x^2 + y^2

ii) Product of x and y subtracted from 9

The product of x and y is x * y = xy

Subtracting these from 9, we have;

9-xy

How can I find a? (Trigonometric Ratios)

earnstyle [38]

Step-by-step explanation:

Hey there!

Use cos ratio to find the value of 'a'.

As per given, we can state that it is a Right angled triangle, so taking 38° reference angle.

We get;

p = AC

b = 6

and h= a

Here, Use the value of b, h and 38° angle to find the value of a.

$\cos(38° ) = \frac{b}{h}$

$\cos(38°) = \frac{6}{a}$

$0.7881 = \frac{6}{a}$ [ cos(38°=0.7881]

$0.7881a = 6$

$a = \frac{6}{0.7881}$

Therefore the measure of a is 7.61 Or 8.

Hope it helps..
