The sum of two polynomials is 8d5 – 3c3d2 + 5c2d3 – 4cd4 + 9. If one addend is 2d5 – c3d2 + 8cd4 + 1, what is the other addend?

Answers

Answer 1

Answer: This one is a bit confusing but I'll try to answer. Since the sum is given and one of the addend is given, we need to perform subtraction to get the other addend.

8d⁵ - 3c³d² + 5c²d³ - 4cd⁴ + 9 ⇒ SUM
- 2d⁵ - c³d² + 8cd⁴ + 1 ⇒ 1ST ADDEND
6d⁵ - 2c³d² + 5c²d³ -12cd⁴ - 8 ⇒ 2ND ADDEND

Answer 2

Answer:

Answer:

A which is 6d5 – 2c3d2 + 5c2d3 – 12cd4 + 8

My question is what is 4-5h how do you solve this problem

Answers

Let us assume that 4 - 5h = 0

we need to the value of h.

4 - 5h = 0
-5h = -4
-5h/-5 = -4/-5
h = 4/5

To check: substitute h by its value.
4 - 5h = 0
4 - 5(4/5) = 0
4 - 20/5 = 0
4 - 4 = 0
0 = 0

Set the expression equal to 0.
4 - 5h = 0

Add 4 on both sides.
5h = 4

Divide by 5 on both sides.
h = $\fbox {4/5}$

What conic section does the equation x2 + y2 – 4y – 1 = 0 represent?ellipse

hyperbola

circle

parabola

Answers

The conic section that the above equation represents is a CIRCLE.

Use completing the square for y and put the equation in standard form:
x²+ y² - 4y + [(-4)/2]² - 1 = 0 + [(-4)/2]²
x² + y² - 4y + (-2)² - 1 = 0 + (-2)²
x² + y² - 4y + 4 - 1 = 4
x² + (y - 2)² - 1 = 4
x² + (y - 2)² = 4 + 1
x² + (y -2)² = 5

The radius of the circle is the square root of 5. Its center is found at (0,2)
