Five less than twice what negative number squared is 157 <- put into an expression
-5 + 2(-x^2) = 157
Now simplify:
-5 + -2x^2 = 157
-2x^2 = 162
-2x^2 - 162 = 0
2x^2 + 162 = 0
x^2 + 81 = 0
Answer:
see below
Step-by-step explanation:
(a) the graph is symmetrical about the horizontal axis. It has a maximum value of r = 3 at θ = π.
__
(b) The graph is symmetrical about both the horizontal and the vertical axis. It has a maximum value of r = 1 at θ = 0 and θ = π. (Note this curve has subtle differences from the inner loop of the above curve.)

<em>About how</em>
As with any graphing problem, when doing it by hand, one chooses enough points to give the general shape of the curve. In some cases, quite a few points may be required. It is often helpful to use a spreadsheet for calculating the point values. Here, we've graphed the equations using "technology"--a graphing calculator.

Answer:
18 units
Step-by-step explanation:
Hello, I can help you with this.
Step 1
identify
we have a equation, let's look it
A=6s2
The surface area A of a cube=6(area of a face)
area of face= side*side
so
Area=6*side*side
Step 2
isolate side from the equation

we are looking for a distance, so , we will use only the positive root
Step 3
replace the value of 1944 square units into the equation

so, the value x of a side of a cube with a total
the side of a cube is 18 units when the surface area of the cube shown is 1944 units2
Have a good day.
