Answer:
0.4
Step-by-step explanation:
Multiply without the decimal points, then put the decimal point in the answer
2 has 0 decimal places
0.2 has decimal place
Therefore the answer has 1 decimal places
Answer:
Could you try to re-post the question with a picture of the table?
Well he would start from 0y and point 20e to make a sifishint graph
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:

Step-by-step explanation:
A hyperbola is the locus of a point such that its distance from a point to two points (known as foci) is a positive constant.
The standard equation of a hyperbola centered at the origin with transverse on the x axis is given as:

The coordinates of the foci is at (±c, 0), where c² = a² + b²
Given that a hyperbola centered at the origin with x-intercepts +/- 4 and foci of +/-2√5. Since the x intercept is ±4, this means that at y = 0, x = 4. Substituting in the standard equation:

The foci c is at +/-2√5, using c² = a² + b²:

Substituting the value of a and b to get the equation of the hyperbola:
