Answer:

1. At Kohls Mrs. House would pay $45.00 because %25 = $15 so I just subtracted %.60.00-$15.00.

2.((Number × Percent/100)) + Number

((38 × 15/100)) + 38

5.7 + 38

= 43.7

3. I say that Mrs. House should go-to target. And just by $1.30.

At Kohls, the speaker would be at $45.00.

At target, the speaker would be at $43.70.

$45.00 - $43.70 = $1.30

A pair of dice is rolled. What is the probability that the sum of the two dice will less than 4 given that the first die rolled

leonid [27]

1/6 because the only way the sum can be less than 4 if the first die is a 2 is if the second die is a 1.

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 $r=1$
