Answer:

z1 + z2 = 3

Step-by-step explanation:

Since we are given z1 = 2 + √(3)i and z2 = 1 – √(3)i. The sum of z1 + z2 would be:

(2 + √(3)i) + (1 – √(3)i) = 2 + √(3)i + 1 – √(3)i = 2 + 1 + √(3)i – √(3)i = 3

Hence, z1 + z2 = 3.

what is the measure of the central angle of a circle with a radius 24 ft that intercepts at 10 ft arc? use 3.14 as pie​
Brrunno [24]

Answer:

central angle =23.88°

Step-by-step explanation:

Given:Arc length =10ft

           radius= 24ft

To find : central angle

Formula: Arc length = 2πr.\frac{\theta}{360}°

                ⇒{\theta} = \frac{arc length.360}{2{\pi}{r}}

               ⇒ {\theta} = \frac{10(360{\degree})}{2 (3.14)(24)}

                ⇒{\theta}=23.8853503°

Which statement is true about the y-intercept of a quadratic function?
Dafna11 [192]

Answer:

A.

Step-by-step explanation:

A quadratic function may only intercept the y-axis once. This is because the definition of a y-intercept tells us that it is the point where x = 0. If there are multiple points where x = 0, then the expression cannot be a function. As such, a quadratic function can only have one.

Choice B contradicts the previous statement.

Choice C is wrong because the x-intercept is the zero of the function. This is because at a given x-coordinate that touches the x-axis, the y-coordinate will be 'zero'.

Choice D is wrong because the y-intercept is where x = 0.

I hope this helps!
