The circumference of a circle is 15n cm what is the area of the circle in terms of n
Mice21 [21]

Answer:

Area of circle is \dfrac{225n^{2}}{4\pi} cm^{2}

Step-by-step explanation:

Formula for circumference of circle is given as,

C=2\pi r

Given that C = 15 n cm,

Substituting the value,

15n=2\pi r

Solving above equation for r, divide both side by 2\pi

\dfrac{15n}{2\pi}=\dfrac{2\pi r}{2\pi}

Simplifying,

\dfrac{15n}{2\pi}=r

Formula for area of circle is given as,

A=\pi r^{2}

Substituting the value of r,

A=\pi \left(\dfrac{15n}{2\pi}\right)^{2}

Squaring the parenthesis,

A=\pi \left(\dfrac{225n^{2}}{4\pi^{2}}\right)

Cancelling out the common term,

A=\dfrac{225n^{2}}{4\pi}

Therefore, area of circle in terms of n is A=\dfrac{225n^{2}}{4\pi} cm^{2}

Find the interval on which the curve of y equals the integral from 0 to x of 2 divided by the quantity 1 plus 3 times t plus t s
elena-14-01-66 [18.8K]

y=\displaystyle\int_0^x\frac2{1+3t+t^2}\,\mathrm dt

By the fundamental theorem of calculus,

\dfrac{\mathrm dy}{\mathrm dt}=\dfrac2{1+3x+x^2}

then by standard differentiation,

\dfrac{\mathrm d^2y}{\mathrm dt^2}=-\dfrac{6+4x}{(1+3x+x^2)^2}

y is concave upward whenever \dfrac{\mathrm d^2y}{\mathrm dt^2}>0. The denominator is always positive, so the sign is determined by the numerator alone:

6+4x>0\implies x>-\dfrac32

In at least one complete sentence, explain why the graph of y = 2x+1 does not go through
Crazy boy [7]

Answer:

The graph of y = 2x+1 will never go through the point (2,3) because the graph is a linear function which means it goes in a straight line. Knowing this, when y = 3, x = 5 this means that the function will never hit (2,3)
