Answer:

x = 3

LP = 3.5

Step-by-step explanation:

JK and LK are chords of the circle each of 7 units long.

Therefore,

JK = LK

Equal chords are equidistant from the center of the circle.

So,

PS = NS

4x - 6 = 6

4x = 6 + 6

4x = 12

x = 12/4

x = 3

LP = LK/2 ( Perpendicular dropped from the center of the circle to the chord bisects the chord)

LP = 7/2

LP = 3.5 units

Need Help with some Math

tatyana61 [14]

Answer:

Step-by-step explanation:

We can use the Polynomial Remainder Theorem. The PRT states that if we have a polynomial $f(x)$ being divided by a factor in the form of $(x-a)$ , then the remainder of the polynomial is given by $f(a)$ .

We have the polynomial:

$f(x)=3x^{15}-5x^{12}+7x^6-3x^2+12$

And it is being divided by:

$(x+1)$

We can rewrite our factor as:

$(x-(-1))$

Therefore:

$a=-1$

Then our remainder will be:

$f(-1)$

Evaluate:

$\begin{aligned} f(-1)&=3(-1)^{15}-5(-1)^{12}+7(-1)^6-3(-1)^2+12\\&=-3-5+7-3+12\\&=8 \end{aligned}$

So, our remainder will be 8.

Z=7f/r+4 , solve for r

lora16 [44]

Answer:

r = ----------- - 4

Step-by-step explanation:

I will assume that you meant:

z = ------------

r + 4

Solve for r. Start by interchanging z and (r + 4):

r + 4 = -----------

Now subtract 4 from both sides. This isolates r:

r = ----------- - 4
