Answer:

B. integral a to b of v(t) dt.

Step-by-step explanation:

The difference in the odometer reading of car travelling in a straight line between two instants is:

v(t) = \frac{ds}{dt}

ds = v(t)\,dt

s_{B} - s_{A} = \int\limits^{t_{b}}_{t_{a}} {v(t)} \, dt

Hence, the right answer is B.

2. A restaurant employs five people. The two cooks work 36 hours
Cloud [144]

Answer:

Total amount = R5112

Step-by-step explanation:

Let the cooks be C.

Let the waiters be W.

Given the following data;

Number of cooks, C = 2

Number of waiters, W = 3

a. To find the amount earned by each cook;

C = 36 * R36 = R1296

b. To find the amount earned by each waiter;

W = 30 * R28 = R840

c. To find the total amount earned by the employees;

Total amount = 2C + 3W

Total amount = 2(1296) + 3(840)

Total amount = 2592 + 2520

Total amount = R5112

What is the solution of 9|2x – 1| + 4 < 49?
luda_lava [24]

Answer: -2

Step-by-step explanation:

You need to set up two cases (Positive case and negative case) and solve for "x".

- POSITIVE CASE IF: 2x-1>0

9(2x -1) + 4 < 49\\18x-9

- NEGATIVE CASE IF: 2x-1

-9(2x -1) + 4 < 49\\-18x+9

Therefore, the solution is:

-2

Find the arc length of the partial circle. <br>length is 1.<br>**See attached photo**<br>​
KatRina [158]

Arc length of the quarter circle is 1.57 units.

Solution:

Radius of the quarter circle = 1

Center angle (θ) = 90°

To find the arc length of the quarter circle:

$\text{Arc length}=2 \pi r\left(\frac{\theta}{360^\circ}\right)

                 $=2 \times 3.14  \times 1\left(\frac{90^\circ}{360^\circ}\right)

                $=2 \times 3.14  \times 1\left(\frac{1}{4}\right)

Arc length = 1.57 units

Arc length of the quarter circle is 1.57 units.
