Solve for the value of k. (k+8) 400

pashok25 [27]

Answer:

value of k = 6

Step-by-step explanation:

sum of all angles forming a straight line = 180°

so,

7k + 8 + 90 + 40 = 180
7k + 138 = 180
7k = 180 - 138
7k = 42
k = 42/7
k = 6

hence the value of k = 6

A stone is dropped into a lake, creating a circular ripple that travels outward at a speed of 60 cmys. Find the rate at which th

storchak [24]

Answer:

a) $t = 1\,s$ , $\dot A \approx 22619.467\,\frac{cm^{2}}{s}$ , b) $t = 3\,s$ , $\dot A \approx 67858.401\,\frac{cm^{2}}{s}$ , c) $t = 5\,s$ , $\dot A \approx 113097.336\,\frac{cm^{2}}{s}$ . The rate at which the area within the circle is increasing linearly inasmuch as time passes by.

Step-by-step explanation:

The area of a circle is described by the following formula:

$A = \pi \cdot r^{2}$

Where:

$A$ - Area, measured in square centimeters.

$r$ - Radius, measured in centimeters.

Since circular ripple is travelling outward at constant speed, radius can be described by the following equation of motion:

$r (t) = \dot r \cdot t$

Where:

$\dot r$ - Speed of the circular ripple, measured in centimeters per second.

$t$ - Time, measured in seconds.

The rate of change of the circle is determined by deriving the equation of area and replacing radius with the function in terms of the speed of the circular ripple and time. That is to say:

$\dot A = 2\cdot \pi \cdot r \cdot \dot r$
