Cos<span> 42° ~ 0.743

cos 42° = sin(90-42) = sin 58°

So sine of complementary angle also has same value as cos 42.
So sin 58 ~ 0.743

Tommy has a stack of 8 pancakes. Each pancake has a radius of 9
chubhunter [2.5K]

Answer:

254.47 cm^2

Step-by-step explanation:

First you have to know the formula for the area of a circle which is:

<h2>A=\pi r^2</h2>

In the word problem it gives us the radius of a pancake which is 9 cm, so we just need to plug it into<em> r </em>in our formula:

<h2>A=\pi r^2</h2><h2>A=\pi (9)^2</h2>

A ≈ 254.47 cm^2

What is the equation of a line, in general form, that passes through points (-1, 2) and (5, 2)? y - 2 = 0 x - 2 = 0 y - x - 2 =
enot [183]

The point-slope form:

y-y_1=m(x-x_1)\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-1, 2) and (5, 2). Substitute:

m=\dfrac{2-2}{5-(-1)}=\dfrac{0}{6}=0\\\\y-2=0(x-(-1))\\\\y-2=0

<h3>Answer: y - 2 = 0.</h3>

Hi there!

The correct answer is: 2x^{2} + y^{2} + z^{2}  - 2\sqrt{2} xy - 2\sqrt{2} xz + 2yz

Step-by-step explanation:

First of all I want to clarify I used to the fourth identity to solve this problem.

The fourth identity is: (x+y+z)^{2}  = x^{2}  + y^{2} + z^{2} + 2xy + 2xz + 2yz

<span>If you deposit(P) $6,800 in a money-market account that pays an annual interest rate(r) of 5.7%. The interest is compounded quarterly(4). [ The money you have after 3 years(t) is: Using the compound interest formula A=P(1+r/n)^nt, where P=$6800, r=57%=.057,t=+3, n=4. A=$6,800(1+(0.057/4))^(3x4) =$6,800(1+0.01425)^12 =$6,800(1.01425)^12 =$6,800(1.18505961016) =$8,058.41. ]</span>
