The coordinates of the parabolas vertex is (1,-5)

Next, the domain is (-infinity, infinity) and so is the range.

The minimum is -5 and the maximum is infinity.

I hope this helps!

Susan divides the fraction 5/8 by 1/16 . Her friend Robyn divides 5/8 by 1/32 predict which person will get the greater quotient

MrRa [10]

So when you divide fractions, you keep the first fraction (in this case 5/8) then change the sign from divide to multiply, then flip the second fraction (we’ll use 1/16 first)

So 5/8 times 16/1. 80/8. Simply to 10.

Now do the same with 5/8 and 1/32

5/8 times 32/1. 160/8. Simplify to 20.

So I good prediction would be 1/32 since you have to flip the divisor and multiply.

The measure of angle zero is 600°. The point XY corresponding to zero on the unit circle is

Andrej [43]

<u>Answer:</u>

$x= -\frac{1}{2}\\\\ y= -\frac{\sqrt{3}}{2}$

<u>Step-by-step explanation:</u>

We are given that the measure of angle θ is 600° and we are to fin the point (x, y) corresponding to angle θ on the unit circle,

We know that the x,y coordinates in the unit circle are the cosine and sine ratios, respectively.

θ = 600

1 unit circle= 360°

It means that 600° corresponds to 600° - 360° = 240°.

So, θ = 360° + 240°

180° < 240° < 270° (this tells that the point is in the third quadrant and its coordinates are negative)

240° - 180° = 60° (using the supplementary angles to find the sin and cos) $\sin 60^\circ = \frac{\sqrt{3}}{2}\\\\\cos 60^\circ= \frac{1}{2}$

Therefore, the x-coordinate is the cos of the given angle while y-coordinate is the sine of the given angle and the coordinates are:

$x= -\frac{1}{2}\\\\ y= -\frac{\sqrt{3}}{2}$

The sum of three consecutive integers is 208.

joja [24]

Answer:

68 1/3 + 69 1/3 + 70 1/3 = 208

Step-by-step explanation:

Sorry if it can't have a fraction but it should be 68 1/3 + 69 1/3 + 70 1/3 = 208.
