Answer:

2.46 × 10⁵

Step-by-step explanation:

The decimal point is after the first non-zero digit.

⇒ 2.46

Multiply the number with base 10 and an exponent which will equal to 246,000.

⇒ 10⁵

Transform each polar equation to an equation in rectangular coordinates and identify its shape.

Gemiola [76]

Answer:

(a) $x ^ 2 + y ^ 2 = 6 ^ 2$

(b) $(x-1) ^ 2 + y ^ 2 = 1$

Step-by-step explanation:

Remember that to convert from polar to rectangular coordinates you must use the relationship:

$x = rcos(\theta)$

$y = rsin(\theta)$

$x ^ 2 + y ^ 2 = r ^ 2$

In this case we have the following equations in polar coordinates.

(a) $r = 6$ .

Note that in this equation the radius is constant, it does not depend on $\theta$ .

As $r ^ 2 = x ^ 2 + y ^ 2$

Then we replace the value of the radius in the equation and we have to::

$x ^ 2 + y ^ 2 = 6 ^ 2$

Then $r = 6$ in rectangular coordinates is a circle centered on the point (0,0) and with a constant radius $r = 6$ .

(b) $r = 2cos(\theta)$

The radius is not constant, the radius depends on $\theta$ .

To convert this equation to rectangular coordinates we write

$r = 2cos(\theta)$ Multiply both sides of the equality by r.

$r ^ 2 = 2 *rcos(\theta)$ remember that $x = rcos(\theta)$ , then:

$r ^ 2 = 2x$ remember that $x ^ 2 + y ^ 2 = r ^ 2$ , then:

$x ^ 2 + y ^ 2 = 2x$ Simplify the expression.

$x ^ 2 -2x + y ^ 2 = 0$ Complete the square.

$x ^ 2 -2x + 1 + y ^ 2 = 1$

$(x-1) ^ 2 + y ^ 2 = 1$ It is a circle centered on the point (1, 0) and with radio $r=1$

What is f(-2) for the function f(x)= -3x + 8

NISA [10]

Answer:

$f(-2)=14$

Step-by-step explanation:

Given function:

$f(x)=-3x+8$

To find $f(-2)$

For the given linear function the $x$ value represents the input values of the function or the domain of the function while $f(x)$ represents the output values or the range of the function and is often refereed to as the $y$ values of the function.

In order to find $f(-2)$ we will plugin -2 in place of $x$ in the function and evaluate it. It means our input value =-2 and we need to calculate the output value.

Thus,

$f(-2)=-3(-2)+8$
