Answer:

5 units to right and 23 units down

Step-by-step explanation:

The vertex of f(x)=x^{2} is at (0,0).

In order to find the vertex of function a(x), we convert the function a(x) to vertex form.

The general vertex form is y=a(x-h)^{2} +k.

Here, (h,k) is the vertex.

a(x)=x^{2} -10x+2\\ a(x)=(x-5)^{2}-25+2=(x-5)^{2}-23

So, the vertex of the graph of a(x) is at (5,-23) and the vertex of f(x) is at (0,0).

Therefore, in order to translate (0,0) to (5,-23), we have to move the vertex of f(x) 5 units to right and then 23 units down.

The measure of an angle is 28 degrees less than its supplement. find the supplement
barxatty [35]

Supplementary angles measure 180°. Make an equation:

x+(x+28) = 180

Subtract 28 to leave the variable in the parentheses alone:

x+(x+28-28) =180-28 \\ x+x = 152

Add the 2 x's together:

x+x = 2x

Your new equation is:

2x=152

Divide both sides by 2 to leave the variable alone

\frac{2x}{2} = \frac{152}{2}  \\ \\ x = 76

The supplement measures 76°

We're told (5,-2) is on the line, that's x=5, y=-2


First one y-5 = -7, (x+2)/3=7/3, not equal


Second one y+5=3, (x-2)/3=1, not equal


Third one y+2=0, (x-5)/3=0, TRUE, equal


Fourth one, y-2=-4 (5+5)/3=10/3, not equal



Answer: third choice y+2 = (1/3)(x+5)

Draw a diagram of the archway modeled by the equation y = -x2 + 5x + 24. Find and label the y-intercept and the
Delvig [45]

Answer:

Width of the archway at its base: 11 units, height of the archway at its highest point: 30.25 units.

Step-by-step explanation:

The graph that represents the equation y = -x^{2} + 5\cdot x + 24 is now sketched with the help of a graphing tool and whose representation is included in a file attached below. The point associated with x-intercepts are (-3, 0) and (8, 0) and the point associated with the highest point is (2.5, 30.25). The width of the archway at its base (\Delta x) and the height of the archway at its highest point (\Delta y) are, respectively:

\Delta x = 8 - (-3)

\Delta x = 11

\Delta y = 30.25

Width of the archway at its base: 11 units, height of the archway at its highest point: 30.25 units.
