Identify the vertex of the function f(x) = |x-^1/2|-2

the negative will shift the graph right, so x = 1/2

the negative 2 will shift the graph down, so y = -2

Thus, the vertex is (1/2, -2)

After a dilation with a center of (0, 0), a point was mapped as (4, –6) → (12, y). A student determined y to be –2. Evaluate the

That would not be right because 4 times 3 equals 12 and -6 times 3 equals -18.

The kite is directly 35.707 yards high above Erika

Step-by-step explanation:

Given scenario forms a right triangle where the length of string is the hypotenuse and the distance between Mary and Erika is the base.

So

H = 50\ yards\\B = 35\ yards

We have to find the perpendicular

Using pythagoras theorem,

H^2 = B^2 + P^2

Putting the values

(50)^2 = (35)^2 + P^2\\2500 = 1225 + P^2\\P^2 = 1275\\

Taking square root on both sides

\sqrt{P^2} = \sqrt{1275}\\P= 35.707

Hence,

The kite is directly 35.707 yards high above Erika

Mario has a business selling muffins. Let x be the price of a muffin. Then, the profit P for Mario’s business is given by p(x)=-
Rufina [12.5K]
To make a positive profit p(x)>0 we need to make:
-100 x^{2} +350x-150 \ \textgreater \  0

Now we solve this for x:
-2 x^{2} +7x-3 \ \textgreater \ 0

We have:
a = -2
b = 7
c = -3

We will use formula for quadratic equation:
x_{1} =  \frac{-b+ \sqrt{ b^{2}-4ac } }{2a}  \\  \\  x_{2} =  \frac{-b- \sqrt{ b^{2}-4ac } }{2a}  \\  \\  x_{1} =  \frac{-7+ \sqrt{ 49-24 } }{-4} = \frac{-7+5 }{-4} = \frac{-2 }{-4} = \frac{1}{2}  \\  \\  x_{2} =  \frac{-7- \sqrt{ 49-24 } }{-4}  = \frac{-7-5 }{-4} = \frac{-12 }{-4} = 3

We got two solutions. One is fraction other is whole number. We will not consider fraction because the amount of muffins sold must be whole number. So our solution is:
x>3
