What is the value of b?

Mathematics
1 answer:
astra-53 [7]3 years ago
5 0

Answer:

Step-by-step explanation:

The line has two clear points (6,10) and (2,2)

y=mx+b

m=(y2-y1)/(x2-x1)

m=(2-10)/(2-6)=-8/-4=2 so far our line is

y=2x+b, using point (2,2) we can solve for b

2=2(2)+b

2=4+b

b=-2 so our line is

y=2x-2, and we want to know the coordinates for (4,b)

b=2(4)-2

b=8-2

b=6

Now we want to know the coordinates for (a,8)

8=2a-2

10=2a

a=5

PLease dont answer if you dont know...<br> Use the Law of Sines to find side "b" of the triangle.
alexdok [17]
Using the law of sins:

side a / sin (angle A) = side b / sin(Angle B)

Side a is opposite angle A, so from the picture we know side a = 50, angle A is 58 degrees and angle B is 48 degrees.

replace those values in the formula we get:

50 / sin(58) = b/ sin(48) 

so now we can cross multiply the 2 fractions to get:

50 * sin(48) = b*sin(58)

to get b by itself, divide both sides by sin(58) to get:

b = (50*sin(48)) / sin(58)

b = 43.82

 You may need to round the answer as needed.

You've decided to go cave diving. the route between a and b in 8025 meters long and the average diver can swim 15 meters per min
Anastasy [175]

\text{The route between A and B is 8025 meters.}\\&#10;\\&#10;\text{And an average diver can swim 15 meters per minute.}\\&#10;\text{we need to find the time it will take to complete diving.}\\&#10;\\&#10;\text{by the time distance formula, we know that}\\&#10;\\&#10;\text{Time}=\frac{\text{Distance}}{\text{Speed}}\\&#10;\\&#10;\text{so using this the time taken to complete the dive is}\\&#10;\\&#10;\text{Time}=\frac{8025}{15}\\&#10;\\&#10;\Rightarrow \text{Time}=535 \text{ minutes}

So the time taken to complete the dive is: 535 minutes
