Answer:
AB = √116 ≈ 10.77
Step-by-step explanation:
Use the formula that calculate the distance between two points:
L means length
For the x and y, substitute a coordinate value that you will label as set 1 or 2.
For example:
A (-3, 7) will be set 1. x₁ = -3 y₁ = 7
B (7 , 3) will be set 2. x₂ = 7 y₂ = 3
Substitute the points into the formula to find the length AB. Simplify.
Solve inside the brackets first
Square each term under the root
Add under the root
Final exact answer is radical (root) form
Final approximate or rounded answer to 2 decimals
The length of AB is the squareroot of 116, or about 10.77 units.
Let
C----------> the center of a circle
C (-4,5)
A-----------> a point on the circle
A (-9,10)
we know that
the distance between point A and point C is the radius of the circle
A (-9,10) C (-4,5)
d=√[(y2-y1)²+(x2-x1)²]--------> √[(5-10)²+(-4+9)²]
=√[(-5)²+(5)²]------> √[(25)+(25)]---------> √50
d=7.07 units
r=d--------> r=7.07 units
the equation of a circle is
(x+4)²+(y-5)²=50
see the attached figure
the answer is
the radius of a circle is 7.07 units
The answer to this question would be: B. JK and LM meet at a right angle.
The reversed T symbol in this question means "perpendicular". That means the JK and LM line have 90-degree angle difference. A straight angle is 180 degree and right angle mean 90 degrees.
A perpendicular line should be in the same plane and intersect each other.
Answer:
≈ 108 m³
Step-by-step explanation:
You're searching for the volume of a cylinder. The formula needed to find it is V=πr²h.
In this case, the radius r is 1.4m and the height h is 35/2=17.5m, as it is only half filled.
Now when inserting values, you get: V=π*1.4²*17.5 which is 107.757 m³
