If there are six 5’s times each other then you would exponent 5^6
Yes that is a true proportion
You can find the x intercept by setting y to 0 and factor the equation.
0=2x^3+3x-2
0=(2x-1)(x+2)
We can make this equation =0 if x is -2 and 1/2.
So the x intercepts are (-2,0) and (0.5,0)
Answer: 138.63 mm²
Step-by-step explanation:
First, we will solve for the area of the rectangle.
A = L * W
A = 15 mm * 5 mm
A = 75 mm²
Next, we will solve for the area of the semi-circles. Since there are two equivalent semi-circles, I will find the area of one circle with the same radius as these two.
First, we need to find the radius.
15 mm - 3 mm - 3mm = 9mm, 9 mm / 2 = 4.5 mm
A = πr²
A = π(4.5)²
A ≈ 63.62 mm²
Lastly, we will add them together.
75 mm² + 63.62 mm² = 138.63 mm²
Answer:
x < 100
Step-by-step explanation:
x - 19 < 81
* add 19 to each side *
- 19 + 19 cancels out
81 + 19 = 100
x < 100
