We are given the diameter of the circle, I assume. In this case, the formula of the area of the circle is expressed as A = pi d^2/4. where pi is a constant. The only option taht makes sense here is C. 6.25 in2. This should have the constant pi on it.

we know that

the area of the circle is equal to

A=\pi r^{2}

where

r is the radius of the circle

In this problem we have

Diameter=5\ in\\r=Diameter/2\\r=5/2\\r=2.5\ in

substitute the value of r in the area's formula

A=\pi*2.5^{2}

A=6.25\pi\ in^{2}

therefore

<u>the answer is</u>

6.25\pi\ in^{2}

Answer:

c.

Step-by-step explanation:

2x² - 4x - 3 = 0

x= \frac{-b+/-\sqrt{b^{2}-4ac} }{2a} \\\\x= \frac{-(-4)+/-\sqrt{(-4)^{2}-4*2*(-3)} }{2*2} \\\\x= \frac{4+/-\sqrt{16+24} }{4} \\\\x= \frac{4+/-\sqrt{40} }{4} = \frac{4+/-2\sqrt{10} }{4}=\frac{2+/-\sqrt{10} }{2}

An ice cube is melting, and the lengths of its sides are decreasing at a rate of 0.8 millimeters per minute At what rate is the
julia-pushkina [17]

Answer:

The rate of decrease is: 43.2mm^3/min

Step-by-step explanation:

Given

l = 18mm

\frac{dl}{dt} = -0.8mm/min ---- We used minus because the rate is decreasing

Required

Rate of decrease when: l = 18mm

The volume of the cube is:

V = l^3

Differentiate

\frac{dV}{dl} = 3l^2

Make dV the subject

dV = 3l^2 \cdot dl

Divide both sides by dt

\frac{dV}{dt} = 3l^2 \cdot \frac{dl}{dt}

Given that: l = 18mm and \frac{dl}{dt} = -0.8mm/min

\frac{dV}{dt} = 3 * (18mm)^2 * (-0.8mm/min)

\frac{dV}{dt} = 3 * 18 *-0.8mm^3/min

\frac{dV}{dt} = -43.2mm^3/min

<em>Hence, the rate of decrease is: 43.2mm^3/min</em>

If the least value of n is 3, which inequality best shows all the possible values of n?
andrezito [222]

Answer:

1) B. n ≥ 3

2)A. 5x – 9

Step-by-step explanation:

1)

If the least value of n is 3 then all the values of n must be greater or equal to 3

Thus the correct option is B :n ≥ 3

2)

Given:

Milo's age is 9 years less than 5 times Pearl's age

Pearl's age is x years

5 times Pearl's age= 5x

then milo's age= 5x-9

so the correct option is A. 5x – 9 !
