Think of a circle. We know it (and all circles) measure 360°. If you think about bisecting that circle, you would divide its 360° by 2, which results in 180°. The circle becomes a half-circle after being bisected, and its straight side (a straight angle) is 180°.
I've attached a diagram illustrating this.
Answer:
9.16
Step-by-step explanation:
It's hundreds so you have to move the decimal place two times
Answer:
x-intercept is -1; y-intercept is 0.5.
Step-by-step explanation:
The x-intercept is relatively easy to read off. It's the x-value where the graph crosses the x-axis, and here is (-1,0).
The y-intercept is best estimated as (0,+0.5).
The correct answer is the 3rd one on the list.
F ( x ) = ( x + 7 ) ( x + 4 ) - ( x + 5 ) ( x + 2 ) =
= ( x² + 4 x + 7 x + 28 ) - ( x² + 2 x + 5 x + 10 ) =
= ( x² + 11 x + 28 ) - ( x² + 7 x + 10 ) =
= x² + 11 x + 28 - x² - 7 x - 10 = 4 x + 18
Answer:
The area of the shaded region is 4 x + 18.
The correct answer is the last option
