A circle has a circumference of 654 units. Approximate the diameter of the circle.

2 answers:

5 0

When you find a diameter of a circle, you probably used this formula:
C = $\pi$ d

If we algebraically manipulate the formula, we get it to find the diameter with a circumference.

Divide both sides by $\pi$ .

C / $\pi$ = $\pi$ d / $\pi$ .
$\frac{C}{ \pi }$ = d
d = $\frac{C}{ \pi }$

We know the circumference is 654 and we will use 3.14 for $\pi$ .

Plug in the values.

d = $\frac{654}{3.14}$
d ≈ 208.3

So, the diameter of the circle is about 208.3 units.

Write an equation of the line perpendicular to the given line that contains P.

Yakvenalex [24]

Answer:

y +5 = -1/3(x -3)

Step-by-step explanation:

The slope of the given line is 3. The slope of the perpendicular line is the negative reciprocal of that, -1/3. Then the point-slope equation is ...

y -y1 = m(x -x1) . . . . line with slope m through point (x1, y1)

y -(-5) = -1/3(x -3)

y +5 = -1/3(x -3)

The difference of twice a number G and 10 is 24. Please help me as I'm stumped! Thank you!

arlik [135]

Twice the number G is 2×G.
The difference between 2G and 10 is 24.
2G - 10 = 24
2G = 24 + 10
2G = 34
G = 34/2
G = 17

Find the degree of the polynomial 2x^4y^2+9x^2y^5-3x^4y^4

coldgirl [10]

Answer:

the polynomial has degree 8

Step-by-step explanation:

Recall that the degree of a polynomial is given by the degree of its leading term (the term with largest degree). Recall as well that the degree of a term is the maximum number of variables that appear in it.

So, let's examine each of the terms in the given polynomial, and count the number of variables they contain to find their individual degrees. then pick the one with maximum degree, and that its degree would give the actual degree of the entire polynomial.

1) term $2\,x^4\,y^2$ contains four variables "x" and two variables "y", so a total of six. Then its degree is: 6

2) term $9\,x^2\,y^5$ contains two variables "x" and five variables "y", so a total of seven. Then its degree is: 7

3) term $-3\,x^4\,y^4$ contains four variables "x" and four variables "y", so a total of eight. Then its degree is: 8

This last term is therefore the leading term of the polynomial (the term with largest degree) and the one that gives the degree to the entire polynomial.
