Answer:
x = 0.5 to the nearest 1/10.
Step-by-step explanation:
3^-x = x^3 + x
y = x^3 - 3^-x + x = 0
Using a graphing calculator to draw the graph of the above:
The graph crosses the x-axis at x = 0.4798
Answer:
The roots are
![x=\frac{1}{6} [3+ i\sqrt{3}]](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B6%7D%20%5B3%2B%20i%5Csqrt%7B3%7D%5D)
![x=\frac{1}{6} [3- i\sqrt{3}]](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B6%7D%20%5B3-%20i%5Csqrt%7B3%7D%5D)
Step-by-step explanation:
we have
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
so
substitute in the formula
Remember that
so
![x=\frac{1}{6} [3\pm i\sqrt{3}]](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B6%7D%20%5B3%5Cpm%20i%5Csqrt%7B3%7D%5D)
The roots are
7.7 cm Because the sides of similar figures are in direct proportion to each other
Answer:
- Colin's third number was 2
- April's sixth number was the same as Colin's first number.
- April's second number was 8.

Third number = 2
Fourth number = 3
Fifth number = 4
Sixth number = 5
April:
First number = 10
Second number = 8
Third number = 6
Fourth number = 4
Fifth number = 2
Sixth number = 0
I hope this helps :)
