The hypotenuse will be bigger than either of the legs so we can rule out B and C. It will be pretty close to the diagonal of a 3×3 square so 3√2 = 3 × 1.4 = 4.2. Our preliminary guess is A.
Choice A
5 lbs is 80 ounces
divide the number of ounces by 14 to get about 5.7 bags of carrots
<h3>
Explanation:</h3>
In the graph x-coordinate represents the number of wind chimes sold and y-coordinate represents the profit Madison earned. If a point is below the x-axis, means it has negative y-coordinate than it represents loss. Points above x-axis should have x-coordinate more than 6 as stated in the question that she started earning profit after selling her first 6 wind chimes. All the points having x-coordinate less than 6 should lie on or below the x-axis.
By the above statement point B is completely wrong. Point C and Point A are also wrong as they both x-coordinate more than 6 but still they are below x-axis.
Point D is the makes most sense here as it has x-coordinate more than 6 and it is above x-axis. This means that when Madison sold 7 wind chimes she was in a profit of $3.75.
Answer:
f⁻¹(1/5) = 2
Explanation:
If f(x) = (2x -3)/5
To find inverse of f(x), make x the subject.
Then,
To find f⁻¹(1/5), simplify insert [x = 1/5 or 0.2]
which yields
6.6c - 3.6c - 2.3c = 0.7c
3.3m² + 4.9m² = 8.2²
=0.7c + 8.2²
