Answer:
Step-by-step explanation:
You can solve it using the calculator that came with windows -- as far back as windows 7. It probably goes back even further, but that's all I can guarantee. Your phone might be able to do it as well.
y = 25000 * 0.007^5
y = 25000 * 1.6807 *10^-11
y = 0.00000042 is what my calculator gives.
Windows can probably do better.
The inequalities is given by x + y ≤ 120, 4.75x + 7.5y > 690 and y ≥ 80. A possible solution is selling 10 tacos and 100 burritos
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.
Let x represent the number of tacos and y represent the number of burritos sold, hence:
x + y ≤ 120 (1)
Also:
4.75x + 7.5y > 690 (2)
and:
y ≥ 80 (3)
The inequalities is given by x + y ≤ 120, 4.75x + 7.5y > 690 and y ≥ 80. A possible solution is selling 10 tacos and 100 burritos

Answer:
7.86 km
Step-by-step explanation:
Let x represent the distance point P lies east of the refinery. (We assume this direction is downriver from the refinery.)
The cost of laying pipe to P from the refinery (in millions of $) will be ...
0.5√(1² +x²)
The cost of laying pipe under the river from P to the storage facility will be ...
1.0√(2² +(9-x)²) = √(85 -18x +x²)
We want to minimize the total cost c. That total cost is ...
c = 0.5√(x² +1) +√(x² -18x +85)
The minimum value is best found using technology. (Differentiating c with respect to x results in a messy radical equation that has no algebraic solution.) A graphing calculator shows it to be at about x ≈ 7.86 km.
Point P should be located about 7.86 km downriver from the refinery.
Answer:
Reflection in the x-axis
Step-by-step explanation:
If the point (x, y) of the shape is rotated 180° about the origin, it will be transformed into the point (-x, -y).
If the point (-x, -y) is reflected in the Y-axis, it will be transformed into the point (x, -y). This transformation is equivalent to the reflection of (x, y) in the x-axis.
