3 0

Why is the point (4, 3) there but not mentioned??
Anyways, the point that P (3, 0) is after rotating 180° about the origin is (-3, 0).
btw, for 180 rotations about O, just take negative value of (x, y)--> (-x, -y)
That way -(3), -(0) becomes (-3, 0)

Answer:

First figure out how many cups are in a gallon. 16 .

Next multiply 16×3= 48

Finally you divide price per cup or 20.16/ 48.

The cost is .42 cents per cup.

Answer:

$Angle = 54$

Step-by-step explanation:

Given

Kano = 45;

Kwara = 410;

Ogun = 105;

Ondo = 126;

Oyo = 154

Total Distribution = 840

Required

Determine the angle subtended by Ondo (in a pie chart)

The general formula to calculate subtended angle in a Pie chart is;

$Angle = 360 * \frac{Frequency}{Total\ Frequency}$

In this case of Ondo

Frequency = 126

Total Frequency = Total Distribution = 840

Substitute these values in the given formula;

$Angle = 360 * \frac{126}{840}$

$Angle = \frac{360 *126}{840}$

$Angle = \frac{45360}{840}$

$Angle = 54$

Hence, the angle subtended by Ondo is 54

Find the distance between (5, -4) and (-1, -2)

Arisa [49]

Answer: The distance is sqrt(40).

Step-by-step explanation:

Let's use the Pythagorean Theorem (a^2 + b^2 = c^2)

(Look at the image I attached)

Let's set a = 2 and b = 6. The mystery side is c, which is opposite to the right angle that is formed when you draw perpendicular lines from each of the points.

(2)^2 + (6)^2 = c^2 <--- First, we need to simplify

4 + 36 = c^2

40 = c^2 <--- Now, we need to take the square root of both sides.

c = sqrt(40)

So, the distance between (5, -4) and (-1, -2) is sqrt(40). I recommend looking at some videos on Khan Academy if you need more help! Let me know if you want me to attach a link that you can visit.
