Mathematics
1 answer:
svp [43]3 years ago
8 0

Answer:

C

Step-by-step explanation:

In any circle the following ratios are always equal.

\frac{arc}{circumference} = \frac{centralangle}{360} , thus

\frac{48}{circum} = \frac{60}{360} = \frac{1}{6} ( cross- multiply )

circumference = 6 × 48 = 288 cm → C

Write the equation of the line with a slope of 1/2
Arada [10]

Answer:

y = (-1/2)x - 1

Step-by-step explanation:

y - 1 = (-1/2)(x - (-4))

y - 1 = (-1/2)(x + 4)

y - 1 = (-1/2)x -(1/2)(4)

y - 1 = (-1/2)x - 2

y = (-1/2)x -2 + 1

Find the differential of each function. (a) y = tan( 5t ) dy = Correct: Your answer is correct. (b) y = 5 − v2 5 + v2
Trava [24]

Answer:

(a)  dy = 5sec^2(5t) \ dt

(a) \ dy = \frac{-20v}{(5+v^2)^2} \ dt

Step-by-step explanation:

Given;

(a) y = tan(5t)

(b) \ y = \frac{5-v^2}{5+v^2}

Solving for (a)

y = tan(5t)

let u = 5t          

⇒y = tan(u)

du/dt = 5

dy/du = sec²u

\frac{dy}{dt} =\frac{dy}{du} *\frac{du}{dt} \\\\\frac{dy}{dt} = sec^2(u)*5\\\\\frac{dy}{dt} = 5sec^2(u)\\\\\frac{dy}{dt} = 5sec^2(5t)

dy = 5sec^2(5t) \ dt

Solving for b;

let u = 5 - v²

du/dv = -2v

let v = 5+ v²

dv/du = 2v

\frac{dy}{dv} = \frac{vdu - udv}{v^2} \\\\\frac{dy}{dv} = \frac{-2v(5+v^2) - 2v(5-v^2)}{(5+v^2)^2}\\\\\frac{dy}{dv} = \frac{-10v-2v^3-10v+2v^3}{(5+v^2)^2}\\\\

\frac{dy}{dv} = \frac{-10v-10v}{(5+v^2)^2}\\\\\frac{dy}{dv} = \frac{-20v}{(5+v^2)^2}\\\\dy = \frac{-20v}{(5+v^2)^2} dt
