The answer is 12
You can use a calculator for these kind of equations
Answer:
no, it'll become -10. 9 will be greater
Step-by-step explanation:
4lbs of Apples
6lbs of Bananas
You can get this by setting up a system of equations to solve for the amount needed. Let x = lbs of apples and y = bounds of bananas. You can have a total weight function of x + y = 10 and a cost function of .75x + .5y = 6. Solve by multiplying the cost function by -2 and adding through.
The first equation is given to determine A.
cos A = 2/5
A = cos⁻¹(2/5) = 66.42°
Now that we know A, we use this value to the second equation.
4 + 4tan²A = 4 +24.996 4tan²(66.42°) = 24.996 ≈ <em>25</em>
I'm pretty sure the answer would be 14 inches
