A farmer has a field in the shape of a semicircle of diameter 50 m. First,
calculate the length of the semicircle to 1 decimal place.
50 m
Answers
Answer:
157.1 m
Step-by-step explanation:
Here, we want to calculate the length of the semi-circle
This simply refers to the circumference of the semi-circle
Mathematically, the circumference is half that of a full circle
The circumference of a full circle is;
C = pi * d
For half circle or semi-circle;
It is ;
C = (pi * d)/2
D = 50 m
The circumference is thus;
C = 50 * 3.142
C = 157.1 m

[tex] {3x}^{3} + {2x}^{2} - 27x - 18[/tex]
Step-by-step explanation:
1) Use difference of squares: a² - b² = (a + b) (a - b).
[tex]( {x}^{2} - {3}^{2} )(3x + 2)[/tex]
2) Simplify 3² to 9.
[tex]( {x}^{2} - 9)(3x + 2)[/tex]
3) Use The FOIL method: (a + b) (c + d) = ac + ad + bc + bd.
[tex] {3x}^{3} + {2x}^{2} - 27x - 18[/tex]
Therefor, the answer is 3x³ + 2x² + -26x -18.

Which is a zero of the function f(x) = 2x – 6?
2
-3
-6
3
Answers
Answer and explanation:
The answer is actually -3. We already know f(x)/y is equal to 0, so the equation is then simplified to 0 = 2x - 6. You do inverse operation, so then -6 = 2x. Then -6 divided by 2 is -3. So -3 = x. Therefore, the zero of the function f(x) = 2x – 6 is -3.
