Answer:
b=(d-c)/a
Step-by-step explanation:
Just gotta switch them around a bit
V = π × r² × h
The radius of the base is equal to half of its diameter. So, we have:
V = 3,14 × 6,5² × 11
V ≈ 1459.3 cm³
Answer:
It simply means getting rid of the square root or radical in the denominator
Step-by-step explanation:
Rationalizing the denominator simply means getting rid of the square root or radical symbol in the denominator thereby making the denominator to be just a whole number.
For example if we want to rationalize the denominator in; 3/√2
We will multiply the numerator and the denominator by √2 to get rid of the radical in the denominator which is the square root sign.
Thus;
(3/√2) × (√2)/(√2)
This gives;
(3√2)2
Answer:
1. RQ
2. R, Y and V
3. T
4. No
Step-by-step explanation:
If we imagine a plane as a rectangle, we can easily see that planes RSTQ and RVUQ intersect in line RQ. Basically, if two planes intersect each other, that intersection is always a line.
Collinear points lie on the same line. Every two points make a line, so the third one also needs to lie along that line. On the diagram, R, Y and V are the only three points on the same line.
From the diagram, we can infer that QT and TX intersect in point T. Additionally, every two lines intersect in a point (of course, unless they're parallel).
Coplanar points lie in the same plane. Three points are enough to define a plane. Whichever three points (R, Q, W and U) we choose we'll have a plane, but the fourth point won't lie in it. This means they are not coplanar.
Answer:
32 × 2 = 64
Step-by-step explanation:
x is being multiplied by 2 so it would be half of 64.
