Navigators locate an object by measuring its location clockwise direction from due north. The measure of the angle is called the bearing. Suppose a lighthouse's bearing is 135° from an island. Be sure to show and explain all work for each part. Part 1: Find the angle represented by the lighthouse on the unit circle. Part 2: Determine the exact ordered pair associated with the lighthouse on the unit circle. Part 3: Find the exact sine, cosine, and tangent of the angle on the unit circle.

Answer:

38.64 km^2

Step-by-step explanation:

The formula for the area of a trapezoid is:

[tex]\frac{(b_{1}+b_{2})*h}{2}[/tex]

Where b1 and b2 are the bases and h is the height. We are given 2.9 and 10.9 as the bases and 5.6 as the height. We can plug these values into the formula:

[tex]\frac{(2.9+10.9)*5.6}{2}[/tex]

After entering the expression in the calculator, you get:

38.64 km^2

This is the first option.

Answer:

Its general form is ax2 + bx + c= 0, where x is the variable and a, b, and c are constants (a≠ 0).

A≈1052.09

Hope you have a great life

Answer:

49.12 square inches

Step-by-step explanation:

Area of a circle = Pi x r^2

= 3.14 x 4^2

= 3.14 x 16

= 50.24

Half the circle = 25.12 squared inches

Area of a triangle = base x height /2

= 6 x 8 /2

= 24

25.12 + 24 = 49.12 square inches

Answer:  x (4z + y^5) / 4z

Step-by-step explanation:

Answer:

[tex] \displaystyle x = \frac{3}{4} [/tex]

Step-by-step explanation:

we are given that

[tex] \displaystyle P = \left(x, - \frac{ \sqrt{7} }{4} \right)[/tex]

we want to figure out x

remember that,

In unit circle x coordinate is considered cos and y coordinate is considered sin

so in order to figure out x we should figure out the value of cos to do we can consider Pythagoras trig indentity

given by

[tex] \displaystyle \sin ^{2} ( \theta) + { \cos}^{2} ( \theta) = 1[/tex]

we are given sin=-√7/4 thus

substitute:

[tex] \displaystyle \left( - \frac{ \sqrt{7} }{4} \right) ^{2} + { \cos}^{2} ( \theta) = 1[/tex]

simplify square:

[tex] \displaystyle \frac{7}{16} + \cos ^{2} ( \theta) = 1[/tex]

move left hand side expression to right hand side and change its sign:

[tex] \displaystyle \cos ^{2} ( \theta) = 1 - \frac{7}{16} [/tex]

simplify Substraction:

[tex] \displaystyle \cos ^{2} ( \theta) = \frac{9}{16} [/tex]

square root both sides:

[tex] \displaystyle \cos ^{} ( \theta) = \pm\frac{3}{4} [/tex]

since in unit circle cos is x and P belongs to Q:IV negative cos isn't applicable

hence,

[tex] \displaystyle x = \frac{3}{4}[/tex]

Answer:Execute Order 66

Step-by-step explanation:

Answer:

Step-by-step explanation:

Assuming that the original figure is the black one

Area of the original figure = 2 x 3 = 6

A (0,1) -> A’ (0,3)

B (2,1) -> B’ (6,3)

C (2,4) -> C’ (6, 12)

D (0,4) -> D’ (0,12)

AB = 6

BC = 9

Area of the final figure = 9 x 6 = 54

b)

area of the final figure = 9 x area of the original figure

c)

true, because their side are proportional

Answer:

31 feets

Step-by-step explanation:

The sketched triangle of the problem is attached below :

To byian the height h of the tree :

We use the trigonometric relation :

Tan θ = opposite / Adjacent

Tan 52 = h / 25

1.2799416 = h / 25

h = 1.2799416 * 25

h = 31.998540

h = 32 feets

Step-by-step explanation: Since there are 14 horses, 14 - 6 -5 = 3 are black.

a) 3 out of 14 are black, so probability is 3/14 chosen horse will be black

b) 1 - 3/14 = 11/14 probability will not be black

c) 6 are brown and 3 are black, so 9/14 probability chosen horse will be either.

Answer:

Which of the following relations is a function- A

Determine which relation is a function- A

Step-by-step explanation:

A function is a type of relationship where x's do not repeat. So, to solve find where each y has a unique x value. In the first question, A is correct because the x values; -3, 0, 2; never repeat. Then, on the next question A is correct because it is a relation written in slope-intercept form, which is a type of function notation.

Answer:

V = 577 cubic cm

Step-by-step explanation:

V(cyl) = Area of Base x Height

Area of Base = πr²

r = 7/2 or 3.5

h = 15

V = π(3.5)²(15)

V = 577

Answer: 27

Answer:

0.15% of the apples have diameters that are no more than 6.18cm.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 7.23, standard deviation = 0.35.

What percentage of the apples have diameters that are no more than 6.18cm?

6.18 = 7.23 - 3*0.35

So 6.18cm is three standard deviations below the mean.

99.7% of the measures are within 3 standard deviations of the mean. The normal distribution is symmetric, which means that (100-99.7)/2 = 0.15% is 3 standard deviations or more below the mean, and 0.15% is 3 standard deviations or more above the mean.

Thus, 0.15% of the apples have diameters that are no more than 6.18cm.

Step-by-step explanation:

The model will contain 1 ten and 4 ones in each group.

Answer: I don’t know how to solve the area of these shapes. But I know how to find the peeimeter Of this shape.

perimeter=P

finding the P of any shape is like finding the P of a square or rectangle. Is to add up all the sides up like for the 8th one it would be 10+20+20+10 or (10x2)+(20x2)

hope this helps!
