Answer:
(x, y) = (1, -5)
Step-by-step explanation:
Using a graphing calculator to solve equations such as these is quick and easy. It is one of my favorite methods. The attached graph shows the solution is ...
(x, y) = (1, -5)
Answer: 15
Step-by-step explanation:
We know that sin 75 degrees = 0.90659...
Now, to find cos: cos-1 (0.90659) = 15
So the answer is 15.
Answer:
No x-intercept/Zero
Step-by-step explanation:
f(x)=3x(3/4)x-4
To find x-intercept/zero, substitute f(x)=0
0=3x(3/4)x-4
To raise a fraction to a power, raise the numerator and denominator to that power
0=3x 3 x-4/4 x-4
Calculate the product
0=3 x-3/4 x-4
Since the right-hand side is always positive, the statement is false for any value of x
Since there is no solution for f(x)=0, there is no x-intercept/Zero
Area is length • height and a square is equal in all sides, so 81/2 equals 9
Each side is 9 and the perimeter sides add together and a square has four sides
9+9+9+9 or 9 • 4 equals 36
36 square inches is the answer
