Answer:

[See Below]

Step-by-step explanation:

✦ So when we see $x^{2}$ , these are powers or exponents.

✧ We solve them like this:

$7^{2}= 7*7$

$7*7=49$

✦ So the answers would be:

$5^{2}=25$

$(-16)^{-2} =-0.00390625$

$\frac{1}{8^{2} }=0.015625$

Delvig [45]

The correct answer is a
(X+1)^2 - x^2=23
X^2 + 2x + 1 -x^2 =23
2x +1 =23
2x =22
X= 11

X+1= 12

When the area in square units of an expanding circle is increasing twice as fast as its radius in linear units, the radius is...

enot [183]

Answer:

c. $\frac{1}{\pi}$

Step-by-step explanation:

We have been given that the area in square units of an expanding circle is increasing twice as fast as its radius in linear units

We will use derivatives to solve our given problem.

We know that area (A) of a circle is equal to $A=\pi r^2$ .

Let us find derivative of area function with respect to time.

$\frac{dA}{dt}=\frac{d}{dt}(\pi r^2)$

Bring out constant:

$\frac{dA}{dt}=\pi \frac{d}{dt}(r^2)$

Using power rule and chain rule, we will get:

$\frac{dA}{dt}=\pi(2r)* \frac{dr}{dt}$

$\frac{dA}{dt}=2\pi r*\frac{dr}{dt}$ Here $\frac{dr}{dt}$ represents change is radius with respect to time.

We have been given that area of an expanding circle is increasing twice as fast as its radius in linear units. We can represent this information in an equation as:

$\frac{dA}{dt}=2\frac{dr}{dt}$

$2\pi r* \frac{dr}{dt}=2\frac{dr}{dt}$

$2\pi r=2$

$\frac{2\pi r}{2\pi}=\frac{2}{2\pi}$

$r=\frac{1}{\pi}$

Therefore, the radius is $\frac{1}{\pi}$ and option 'c' is the correct choice.

1 Andre tried to solve the equation: 1/4(x+12)=2. What was his mistake.

svetoff [14.1K]

Answer:

the correct answer is x=-4

Step-by-step explanation:

the mistake he made is writing 1/4x=-10 instead of 1/4x=-1

He should have wrote -1 instead of -10
