Answer:
Option 5. Insufficient information
Step-by-step explanation:
Since the pool is in the form of a rectangle. Therefore opposite sides of the pool are equal.
Let the length of the pool be x and width of the pool is y feet.
Jan wants to swim across the diagonal of the pool therefore length of the diagonal will be = √x² + y²
perimeter of the pool is 16 feet
2(x + y) = 160 feet.
Now to get the length of the diagonal we should know at least one side of the pool.
Therefore information is insufficient for the calculation.
Option 5 is correct.
Step-by-step explanation:
expanded notation form. 10+3+0.6+0.05+0.002
expanded factor form. 1x10+3×1+6x0.1+5×0.01+2×.001
exponential form 1x10^1 + 3x10^0 + 6x10^-1 + 5x10^-2 + 2x10^-3
word form is thirteen and six hundred fifty-two thousandths
Answer:
yes The area of a triangle is b x h / 2 (base times height divided by 2)
Answer:
x = -1
Step-by-step explanation:
The usual approach to these is to square the radicals until they are gone.
Each time the equation is squared, the possibility of an extraneous root is introduced. Here, x=3 is extraneous: it does not satisfy the original equation.
The solution is x = -1.
_____
Using a graphing calculator to solve the original equation can avoid extraneous solutions. The attachment shows only the solution x = -1. Rather than use f(x) = 2, we have rewritten the equation to f(x)-2 = 0. The graphing calculator is really good at showing the function values at the x-intercepts.
