Answer:
He can afford 5 large cheese pizzas.
Step-by-step explanation:
$40 ÷ $7.50 = 5.333333
You cannot buy 1/3 of a pizza, so you round the number to a whole number.
5.333333 ----> 5
5 large cheese pizzas
What equation? You would have to pass a photo, but...
Standard form is: ax+by=c
Slope intercept form is: y=my+b
Point slope for is: y − y1 = m(x − x1)
Answer:
y = 4
Step-by-step explanation:
because 5 x 4 = 20 and 20 × 4 = 80 and so on y is equal to four
Answer:
Step-by-step explanation:
if u is an irrational number added to a rational number (sqrt 15) to yield 2, then that would mean u would = root -1.78.....
which means you wouldn't have a real solution. if you want a complex answer, it would be sqrt(1.78)i
Answer:
Step-by-step explanation:
In each case, draw the right triangle which produces the inverse trig value. That is, label the two sides as needed, and calculate the third side.
It should be clear that
![tan(sin^{-1} x/4) = x/\sqrt{16-x^{2} }](https://tex.z-dn.net/?f=tan%28sin%5E%7B-1%7D%20x%2F4%29%20%3D%20x%2F%5Csqrt%7B16-x%5E%7B2%7D%20%7D)
![sin(tan^{-1} x/4) = x/\sqrt{16+x^{2} }](https://tex.z-dn.net/?f=sin%28tan%5E%7B-1%7D%20x%2F4%29%20%3D%20x%2F%5Csqrt%7B16%2Bx%5E%7B2%7D%20%7D)
sin(2α) = 2 sinα cosα
So,
![1/2 sin(2sin^{-1} x/4) = (1/2)(x/4) * x/\sqrt{16-x^2} = x^{2} /(8\sqrt{16-x^2})](https://tex.z-dn.net/?f=1%2F2%20sin%282sin%5E%7B-1%7D%20x%2F4%29%20%3D%20%281%2F2%29%28x%2F4%29%20%2A%20x%2F%5Csqrt%7B16-x%5E2%7D%20%3D%20x%5E%7B2%7D%20%2F%288%5Csqrt%7B16-x%5E2%7D%29)
See what you can do with the others.
