Answer: -3< 0

Step-by-step explanation: this means -3 is less than 0.

As on number line -3 and 0 are marked. We know 0 is origin if we go rightward i .e towards the positive number all numbers are greater than zero.

But if we move leftward on number line the numbers are less than zero.

The endpoints of a diameter of a circle are A(3,1) and B(9,9). Find the area of the circle in terms of pie

andrey2020 [161]

Answer:

The answer is $25\pi$ units squared.

Step-by-step explanation:

If we find the diameter, we can find the radius by halving the diameter.

We can find the diameter by using the endpoints of the diameter.

The distance formula will give us the length between (3,1) and (9,9).

The distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

The distance between the $x$ 's is 9-3=6.

The distance between the $y$ 's is 9-1=8.

The distance between the points is given by $\sqrt{6^2+8^2}=\sqrt{36+64}=\sqrt{100}=10$ .

The radius is therefore $\frac{10}{2}=5$ .

We are asked to find the area of this circle.

The formula for finding the area of a circle is $\pi r^2$ .

Since the radius is $5$ , then the area in terms of $\pi$ ,(pi), is $\pi (5)^2=\pi (25)$ .

The answer is $25\pi$ units squared.

Speed was increased 20% to 48 mph. What was the speed before the increase

grigory [225]

Answer:

40 mph

Step-by-step explanation:

If the speed increased by 20%, now the speed is 120% of the original speed.

48 mph is 120%, so dividing by 6 will get 8 which is 20%.

If 8 is 20%, you can multiply it by 5 to get 40, which is 100%. This means 40 mph is the original speed.

Hope this helps!
