The area of the circle is 95.03.

Area of A circle = Pi r^2
First off, our radius is 5.5’’ because we divided our diameter, 11 inches by 2 which equals to 5.5.

Area of a circle = Pi * R^2
A= Pi * (5.5)^2
A = Pi * 39.25”
A = 94.985.

So, in conclusion, the area of this circle is about 94.985” squared.

Evaluate the limit, if it exists. lim (h - > 0) ((-7 + h)^2 - 49) / h

baherus [9]

Expand everything in the limit:

$\displaystyle\lim_{h\to0}\frac{(-7+h)^2-49}h=\lim_{h\to0}\frac{(49-14h+h^2)-49}h=\lim_{h\to0}\frac{h^2-14h}h$

We have $h$ approaching 0, and in particular $h\neq0$ , so we can cancel a factor in the numerator and denominator:

$\displaystyle\lim_{h\to0}\frac{h^2-14h}h=\lim_{h\to0}(h-14)=\boxed{-14}$

Alternatively, if you already know about derivatives, consider the function $f(x)=x^2$ , whose derivative is $f'(x)=2x$ .

Using the limit definition, we have

$f'(x)=\displaystyle\lim_{h\to0}\frac{f(x+h)-f(x)}h=\lim_{h\to0}\frac{(x+h)^2-x^2}h$

which is exactly the original limit with $x=-7$ . The derivative is $2x$ , so the value of the limit is, again, -14.

Nick and Adam work out together. Nick weighs 160 pounds and is gaining about 3 pounds per week. Adam weighs 195 pounds and is lo

Inessa [10]

Answer:

$160+3x=195-2x$

Needed 7 weeks

Step-by-step explanation:

Let x be the number of weeks.

Nick

weighs 160 pounds;
is gaining about 3 pounds per week;
gains 3x pounds in x weeks;
weighs 160 + 3x pounds after x weeks.

Adam

weighs 195 pounds;
is losing about 2 pounds per week;
loses 2x pounds in x weeks;
weighs 195 - 2x pounds in x weeks.

The equation that can be used to find the number of weeks that it will take them to weigh the same amount is

$160+3x=195-2x$

Solve this equation:

$3x+2x=195-160\\ \\2x=35\\ \\x=7$
