A boat travels 8 miles north from point A to point B. Then it moves in the direction S 40°W and reaches point Finally, it turns
uysha [10]

Answer:

B.18. 44 miles

Step-by-step explanation:

We are given that

Distance between A and B=8 miles

Angle B=Angle BCQ=40 degree (Alternate interior angles)

Angle ACB=180-Angle ACP-Angle BCQ

Angle ACB=180-40-40=100 degree

In triangle ABC

Angle A+ Angle B +Angle C=180 degree using sum of angles of triangle property

Substitute the values

\angle A+40+100=180

\angle A+140=180

\angle A=180-140

\angle A=40 degree

Angle A=Angle B

When two angles are equal of a triangle then the triangle is isosceles triangle.

Therefore, triangle ABC is an isosceles triangle.

\implies BC=AC

Now, Sine law

\frac{a}{sin A}=\frac{b}{sin B}=\frac{c}{sin C}

Using the sine law

\frac{BC}{sin 40}=\frac{AB}{sin 100}

\frac{BC}{sin 40}=\frac{8}{sin 100}

BC=\frac{8\times sin40}{sin 100}

BC=5.22

AC=BC=5.22 miles

Now, total distance covered by the boat=AB+BC+AC

Total distance covered by the boat=8+5.22+5.22=18.44 miles

Hence, option B is correct.

Create a number pattern that follows the rule
vazorg [7]

Answer:

The pattern form is 8,15,34,71 which follows the rule x^3+7

Step-by-step explanation:

Given : Rule x^3+7

To find : Create a number pattern that follows the rule. Use at least three terms in the pattern ?

Solution :

Rule x^3+7

Put n=1,

x^3+7=(1)^3+7

x^3+7=1+7=8

Put n=2,

x^3+7=(2)^3+7

x^3+7=8+7=15

Put n=3,

x^3+7=(3)^3+7

x^3+7=27+7=34

Put n=4,

x^3+7=(4)^3+7

x^3+7=64+7=71

The pattern form is 8,15,34,71 which follows the rule x^3+7

Can someone help with these and please show work
dsp73

Step-by-step explanation:

3.)

34 + 3√(4 • 6 ÷ 2)^2 + 5^2

34 + 3√(12)^2 + 25

34 + 3√144 + 25

34 + 3√169

34 + 3 × 13

34 + 39 = 73

4.)

|9 - 12 • 3| - 2 + 10/2^2 + 10 - 7

|9 - 36| + 8/4 + 10 - 7

9 + 36 + 8/7 = 53/7

X²-x-12=0<br> Describe the number and types of roots using the discriminant<br> Show steps please
pickupchik [31]

Answer:

2 real roots

Step-by-step explanation:

The discriminant is b^2 -4ac  where ax^2 +bx -c

If b^2 -4ac > 0 we have 2 real roots

b^2 -4ac = 0 we have 1 real root

b^2 -4ac < 0 we have 2 complex roots

x²-x-12=0

a =1 b=-1  c = -12

(-1)^2 - 4(1)*(-12)

1 +48

49 > 0

2 real roots
