Answer:

Step-by-step explanation:

B should be (2,3) and D should be (2, -4) because its just a reflection of the two points. :)

Answer:

B(2, 3) and D(2, −4)

Step-by-step explanation:

Area of rectangle = L x W

AC = 7 units

35 = 7 x W

W = 35/7 = 5

So from Point A, draw 5 units to the right ; B(2,3) and from point B, draw 7 units down D (2,-4).

Rectangle, the opposite sides are equal so AC = BD = 7, AB = CB = 5

An angle measures 15 degrees more than its complement. Find the measures of the two angles

kap26 [50]

Answer:

The first angle is 37.5° and the second would be 52.5°

Step-by-step explanation:

Angles are complementary when their sums add up to 90°.

$x+(x+15) = 90\\x+x+15=90\\x+x=75\\x=37.5$

The first angle is 37.5° and the second would be 52.5°, after we plug in x.

Vladimir [108]

Answer:

$cos^2\theta + sin^2\theta = 1$

Step-by-step explanation:

Given

$(\frac{b}{r})^2 + (\frac{a}{r})^2$

Required

Use the expression to prove a trigonometry identity

The given expression is not complete until it is written as:

$(\frac{b}{r})^2 + (\frac{a}{r})^2 = (\frac{r}{r})^2$

Going by the Pythagoras theorem, we can assume the following.

a = Opposite
b = Adjacent
r = Hypothenuse

So, we have:

$Sin\theta = \frac{a}{r}$

$Cos\theta = \frac{b}{r}$

Having said that:

The expression can be further simplified as:

$(\frac{b}{r})^2 + (\frac{a}{r})^2 = 1$

Substitute values for sin and cos

$(\frac{b}{r})^2 + (\frac{a}{r})^2 = 1$ becomes

$cos^2\theta + sin^2\theta = 1$

A bag contains five red marbles, two orange marbles, one yellow marble, and two green marbles. Two marbles are drawn from the ba

Naya [18.7K]

Option C: 0.8889 is the probability of choosing an orange marble and a green marble.

<h2>Given that:</h2>

Number of red marbles is 5

Number of orange marbles is 2

Number of yellow marbles is 1.

Number of green marbles is 2.

<h2>Explanation and Calculations:</h2>

So there are in total 10 marbles.

Two marbles can be chosen in $^{10}C_2$ ways = 90/8

Now the favorable event is when one green marble and one orange marble is chosen. The number of ways this can be done is $^{2}C_1 \times ^{2}C_1 = 4$

The resultant probability is calculated by:

$P(E) = \dfrac{Number \:of\: Favourable \:cases}{ Number\: of\: total \:cases}\\= \dfrac{4}{\frac{90}{2}}\\\\= \dfrac{8}{90}\\\\\approx 0.08889$

Thus the needed probability is 0.08889 given by option C.
