I have a question that says: Sound is used to measure ocean depth. Sound travels 1.5 km per second through water. If it takes 3.

7 seconds for a sound to reach the bottom of the ocean, how deep is the water? It is not that I can't solve the problem, I don't know the problem is asking. The only thing I know is that it multiplication. Please help me.

Marsha wants to determine the vertex of the quadratic function f(x) = x2 – x 2. What is the function’s vertex? (one-half, seven-
nydimaria [60]

Vertex of the quadratic equation is the highest or the lowest point of the quadratic equation.

<h3>Given-</h3>

The given equation in the question is,

f(x) = x^2 - x +2

<h3>Vertex of the quadratic equation</h3>

Vertex of the quadratic equation is the highest or the lowest point of the quadratic equation.

To find the vertex of the equation we need to compare the given equation with the following equation.

f(x)=a(x-h)^2+k

Here h and k are the vertex of the equation.

The given equation is,

f(x) = x^2 - x +2

Rewrite the equation,

f(x) = x^2 - x +(\dfrac{1}2)^2} +2-(\dfrac{1}2)^2}

f(x) = x^2 - x +\dfrac{1}{4} +2-\dfrac{1}4}

f(x) =(x-\dfrac{1}{2} )(x-\dfrac{1}{2} )+2-\dfrac{1}{4}

f(x) =(x-\dfrac{1}{2} )^2+\dfrac{7}{4}

Thus the vertex of the quadratic equation is 1/2 and 7/4.

G(x)=-x^2-1-2x<br> f(x)=x+5<br> Find (g-f)(x)
nikitadnepr [17]

(g-f)(x) is x² - 3x - 6

<u>Step-by-step explanation:</u>

Step 1:

Given g(x) = x² - 1 - 2x, f(x) = x + 5. Find (g-f)(x)

(g-f)(x) = x² - 2x - 1 - (x + 5) = x² - 2x - 1 - x - 5 = x² - 3x - 6

There are 3 ways you can prove triangles similar without having to use all sides and angles?
bagirrra123 [75]

You can tell if they're similar if they:

1) Have two of the same angles

2) If two pairs of corresponding angles in a pair of triangles are congruent.

3) If they are the same shape
