Answer:
B
Step-by-step explanation:
The area of the square can be calculated using S^2 = x^2
The area of the circle is pi * r^2
= 22/7 * (x-1)^2
= 22(x-1)^2/7
So we need the value of x, that will make;
x^2 = 22(x-1)^2/7
In this kind of scenario, since we have options, it is best to test values instead of going through long calculations
Let’s try 2.29
So;
2.29^2 = 22/7(2.29-1)^2
5.2441 = 5.23
So close , but let’s see if any other value will
give us a closer value
Let’s work with 1.66
1.66^2 = 22/7(1.66-1)^2
2.7556 = 1.369
This is far from what we need
Let’s try 0.5
0.5^2 = 22/7(0.5-1)^2
Thus gives a negative answer on the right hand side, so no need trying
And lastly 1.25
1.25^2 = 22/7(1.25-1)^2
1.5625 = 0.1946
So the first test still gives the most probable answer to a decimal place accuracy
Answer:
Step-by-step explanation:
5x - 8 = 16 -3x
8x - 8 = 16
8x = 24
x = 3
AC= 5(3) - 8 = 15 - 8 = 7
CD= 16 - 3(3) = 16 -9 = 7
7 + 7 = 14 = AD
Answer:
your mark is correct
Step-by-step explanation:
<em>The marked answer choice is correct</em>.
(2, -18) is not a global minimum, because there are function values that are lower.
(0, -6) is not a global maximum, because there are function values that are higher.
A global maximum is also a local maximum.*
_____
* More correctly, a global maximum is either a local maximum or the end point of an interval. No intervals are involved in this question.
We will be using PEMDAS rule here :
P
- Parentheses first
E
- Exponents (ie Powers and Square Roots, etc.)
MD
- Multiplication and Division (left-to-right)
AS
- Addition and Subtraction (left-to-right)
8+2(12-5)
Step 1:
Solving parenthesis first:
8+2(7)
Step 2:
Multiplying 2*7
8+14
Step 3:
Adding 8 and 14
22
Answer is 22
