Answer: c

Step-by-step explanation: this answer is Unknown  

The direction of the boat sail to head directly back to the marina which leaves the marina and sails 13 miles northeast, then 12 miles east is 23.45° W of S.

When the three sides of a triangle is known, then to find any angle, the law of cosine is used.

It can be given as,

[tex]c^2=a^2+b^2-2ab\cos C\\a^2=c^2+b^2-2ab\cos A\\b^2=a^2+c^2-2ab\cos B[/tex]

Here, a,b and c are the sides of the triangle and A,B and C are the angles of the triangle.

A boat leaves the marina and sails 13 miles northeast, then 12 miles east. The image of the problem is attached below.

Thus, the value of the third side is,

[tex]c=\sqrt{12^2+13^2-(2\times12\times13\times \cos 135)}\\c=23.01[/tex]

The measure of the angle x is,

[tex]\angle x=\cos^{-1}\dfrac{23.1^2+13^2-12^2}{2\times23.1\times13}\\\angle x=23^o26'57"\\\angle x=23.449^o[/tex]

Thus, the direction of the boat sail to head directly back to the marina which leaves the marina and sails 13 miles northeast, then 12 miles east is 23.45° W of S.

Answer:

y = -3x + 30

Step-by-step explanation:

A great website to use for graphing is desmos. You first graph the starting 2 points, turn it into a line connecting it, then make an equation. You should get y = -3x + 5, so when we look for something parallel it should have the same slope. I then put into the graph every equation along with the dot (11,-3) and looked to see which intersected.

Answer:

Yes,

Step-by-step explanation:

Because every "x" Value corresponds to exactly one "y" value.

Yes, the relation is a function.

A relation is a function if it has only One y-value for each x-value.

The given relation is {(3,2), (1, -2), (2, -4), (3, -2)}.

We need to check whether the relation is a function or not.

A function is a binary relation between two sets that associates every element of the first set to exactly one element of the second set.

As we observe the given relation three comma two, one comma minus two, two comma minus four comma three comma minus two.

Yes, the given relation is a function because there is no x value is repeated. Every y value has an unique x value.

Hence, the relation is a function.

The value of DA in parallelogram ABCD is 4 inches.

A parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel to each other.

In parallelogram ABCD:

AB = DC, AD = BC

Hence:

8x - 5 = 3x + 10

5x = 15

x = 3 units

AB = 8(3) - 5 = 19 inches

Let y = AD = BC:

AB + BC + DC + AD = perimeter

19 + 19 + y + y = 46

y = 4 inches

The value of DA in parallelogram ABCD is 4 inches.

Step-by-step explanation:

In order to solve this equation, our goal is to "reverse" the equation until we have x isolated on one side.

[tex]6x+4x-5=55[/tex]

We can first combine the x terms.

So x = 6.

Answer:

B

Step-by-step explanation:

y = 3

then x = 2

so b

3 = 3/2(2)

3 = 6/2 = 3

3 = 3

so when x = 1 then 3/2(1) = 3/2 so y = 3/2

Answer:

P(X < 3) = 0.9375

Step-by-step explanation:

If the coins tossed by the 3 people all turn up the same, it means that we will have either; HHH or TTT

H is head and T is tail.

Thus; the probability of failure in each trial is;

q = P(HHH) + P(TTT)

P(H) = ½ and P(T) = ½.

Hence;

q = P(HHH) + P(TTT) = (½ × ½ × ½) + (½ × ½ × ½) = ⅛ + ⅛ = ¼ = 0.25

In binomial probability, p = 1 - q

Thus; p = 1 - 0.25 = 0.75

Now to find the probability that fewer than 3 tosses are needed is given by the expression;

P(X < 3) = P(1) + P(2)

Now, because the toss trials are independent, it means that x = 1.

Since x = 1,we can make use of geometric distribution formula which is given by;

P(X = x) = p^(x) • q^(n - x)

Thus;

P(1) = 0.75^(1) × 0.25^(1 - 1)

P(1) = 0.75 × 1

P(1) = 0.75

P(2) = 0.75^(1) × 0.25^(2 - 1)

P(2) = 0.75 × 0.25

P(2) = 0. 75 × 0.25

P(2) = 0.1875

Thus;

P(X < 3) = 0.75 + 0.1875

P(X < 3) = 0.9375

Answer:

y = (-1/4)x + 3

Step-by-step explanation:

to find the perpendicular slope you just find the reciprocal of 4 which is (-1/4)

then find the y-intercept making the line go through (-8, 5) so you do:

y = (-1/4)x + b

5 = (-1/4)(-8) + b

5 = 2 + b
