Answer:
C
Step-by-step explanation:
over the interval [-1,1], f(x) is greater than 0
<span> f(2) = 2×2 − 1 = 3</span>
The point of intersection is (2, 3).
The example shows that we can find the point of intersection in two ways.
Either graphically, by drawing the two graphs in the same coordinate system, or algebraically by solving the equation such as the one in the above example.
<span>Solving an equation graphically is easy with a graphical calculator or a computer program such as Excel.
Some equations cannot be solved algebraically but we can find solutions that are correct to as many significant figures as we want by using computers and calculators</span>
Answer:
B. Area C is the sum of the areas of A and B
Step-by-step explanation:
This is an illustration of the Pythagorean theorem. The number of squares in C (25) is the total of the numbers of squares in A (16) and B (9).

Answer:
1024/59049
Step-by-step explanation:
P( clear hurdle) = 2/3
There are 10 hurdles
P ( clear all hurdles) = P( clear hurdle) * P( clear hurdle)...... 10 times
= 2/3 * 2/3 *....... 10 times
= (2/3) ^ 10
=1024/59049
