Answer:

Cos(θ) = 8 / 17

Step-by-step explanation:

<em>Cos = Adjacent / Hypotenuse</em>

Side that is adjacent to θ = 8

hypotenuse of the triangle = 17

<u>Cos(θ) = 8 / 17</u>

Hope this helps!

A fisherman yanks a fish vertically out of the water with an acceleration of 2.5! !! using very light fishing line that has a br
Artyom0805 [142]

Two forces act on the fish, and these are:


1) Its weight mg, downwards and 


2) pressure in the string, T, upwards which is 22 N when the string breaks. 
In the result of these two forces, the fish had an acceleration of 2.5 m/s^2 in the upward way. 


So, T - mg = m*2.5


=> m = T / (2.5 + g)


=> m > 22 / (2.5 + 9.8) ( when the string snaps ) 


=> m > 1.79 kg. 


As a result, the mass of the fish is more than 1.79 kg as the line has been broken.

Multiply a Polynomial by a Monomial<br> In the following exercises, multiply.<br> 236. (8b − 1)b
tatyana61 [14]

Answer:

  • The given expression is (8b − 1)b.
  • We have to multiply the given expression.
  • Distribute the expression then simplify to determine the answer.

         (8b − 1)b = 8b*b - 1*b

                        = 8b2 - b

                         

Step-by-step explanation:

Hence the expression (8b − 1)b=8b2 - b.

A landscaping company is delivering crushed stone to a construction site .The Table shows the total weight in pounds W, of n loa
irina1246 [14]

Answer:

Option (C)

Step-by-step explanation:

From the given table,

Dependent variable is the weight of each load and independent variable is number of loads of crushed stones.

Let the equation that represents the total weight is,

W = mn + b

Where 'm' = slope of the line

b = y-intercept

n = number of loads

Since graph starts from the origin (0, 0), y - intercept 'b' will be 0.

Two points lying on the line are (0, 0) and (1, 2000)

Slope of the line 'm' = \frac{y_2-y_1}{x_2-x_1}

                                  = \frac{2000-0}{1-0}

                                  =2000

Therefore, equation will be,

W = 2000n

Option (C) will be the answer.
