<u>The following are the evaluation steps in order for the 8 \times 3 \div\left(4^{2}-13\right)+5^{2}+4 \times 3 given expression:</u>

Step 1: First perform exponentiation inside parentheses

             4^{2}

Step 2: Next, evaluate the contents of parentheses

               (16 – 13)

Step 3: Before any multiplication or division, exponentiation outside parentheses should be done.

               5^{2}

Step 4: Perform multiplication and division from left to right

                8 \times 3

Step 5: Perform multiplication and division from left to right

              \frac{24}{3}

Step 6: Perform multiplication and division from left to right

                4 \times 3

Step 7: After all the multiplication and division, addition should be performed from left to right

                  (8 + 25)  

Step 8: Perform addition from left to right

                    (33 + 12)

Slope of line that passes through points (2,1) and (17,-17)
mojhsa [17]

Answer: y = -1,2x + 3.4

Step-by-step explanation:

y = ax + b

(2,1)      => 1    = 2a + b (1)

(17,-17) => -17 =17a + b (2)

Using caculator Mode => 5 =>1

We get : a=- 1.2 , b = 3.4

=> y = -1.2x + 3.4

Simplify: -c - 8(4c - 5) - (-18c + 3)
d1i1m1o1n [39]

Answer:

-15c + 2

Step-by-step explanation:

you start by multiplying the coefficients of the parentheses to the numbers inside which gives you

- c - 32c + 5 + 18c - 3

then you simply just group together the like numbers. all "c" 's go together and everything without a "c" goes together

- 1c - 32c + 18c= -15c

5 - 3 = 2

the final answer simplified is

-15c + 2

The height, h, in feet of a piece of cloth tied to a waterwheel in relation to sea level as a function of time, t, in seconds ca
Anni [7]

Considering the period of the cosine function, it is found that it takes 40 seconds for the wheel to complete one turn.

<h3>What is the period of the cosine function?</h3>

The cosine function is defined by:

f(x) = acos(bx + c) + d.

For the period, we have to look at coefficient b, and the period is:

P = 2π/|B|

For this problem, the function is given by:

h(x) = 15 cos(π/20)

Hence B = π/20, and the period is:

P = 2π/|B| = 2π/(π/20) = 2 x 20 = 40 seconds.

Hence it takes 40 seconds for the wheel to complete one turn.
