Answer:

if you are looking to solve for x the answer is

$\frac{1}{8}$

Step-by-step explanation:

first you need to gather all the variables (x) to one side of the equation so take right hand side:

2x + 6x = 4 - 3

remember to watch out for the sign changes. then:

$8x = 1$

therefore

$x = \frac{1}{8}$

Find the length of x round your answer to the nearest hundredth

allsm [11]

Answer:

x = 7.55

Step-by-step explanation:

We can use the Pythagorean theorem to solve

a^2 +b^2 = c^2

where a and b are the legs and c is the hypotenuse

a^2 +8^2 = 11^2

x^2 +64 = 121

Subtract 64 from each side

x^2 +64-64 = 121-64

x^2 =57

Take the square root of each side

sqrt(x^2) = sqrt(57)

x = 7.549834435

To the nearest hundredth

x = 7.55

Given a circle with center (h,k) and radius r that has parametric equations x = h + r cos a and y = k + r sin a, find a set of p

horrorfan [7]

Answer: $x=-10+\sqrt{7}\cos \theta\-,\quad y=0.5+\sqrt{7}\sin \theta$

Step-by-step explanation:

For a circle with center $(h,k)$ and radius $r$

The parametric equation is $x=h+r\cos a$ , $y=k+r\sin a$

For center $(-10,\frac{1}{2})$ and radius $\sqrt{7}$

Parametric equation is

$\Rightarrow x=-10+\sqrt{7}\cos \theta\\\Rightarrow y=0.5+\sqrt{7}\sin \theta$
