Vertex: (4,0)

Axis of symmetry: x = 4

Klio2033 [76]3 years ago
4 0

Answer:

Vertex: (4, 0)

Axis of symmetry: x = 4

Step-by-step explanation:

This quadratic is in vertex form.  Vertex form is

y = a(x - h)² + k     where the point (h, k) is the vertex.  

For this equation we have

y = -(1/8)(x - 4)² + 0,   so our vertex is at the point (4, 0)  

*It's positive 4 because the equation is (x - h), so we're subtracting positive 4

The axis of symmetry is the equation of the vertical line that goes through the x coordinate of the vertex (quadratics are symmetric from the vertex)

So the axis of symmetry is x = 4

If the circumference of a circle is 84.5 ft, find the radius.
Elina [12.6K]

Answer:

13.448, rounded off: 13.5 ft

Step-by-step explanation:

r=\frac{C}{2\pi }

Where r = radius, C = circumference.

r=\frac{84.5}{2\pi } =13.448 = 13.5 ft

Five times the sum of the digits of a two-digit number is 13 less than the original number. If you reverse the digits in the two
mafiozo [28]

Answer:

The difference of the original two-digit number and the number with reversed digits is 18.

Step-by-step explanation:

Since it's a two digit number, let x represent the tens digit and let y represent the units digit.

Thus, the original two digit number is;

10x + y.

The reverse two digit number is;

10y + x.

We are told that five times the sum of the digits of the two-digit number is 13 less than the original number.

Thus;

5(x + y) = (10x + y) - 13

Multiplying out the bracket gives;

5x + 5y = 10x + y - 13

Rearranging gives;

10x - 5x + y - 5y = 13

5x - 4y = 13 - - - - (3)

Also,we are told that, four times the sum of its two digits is 21 less than the reversed two-digit number. Thus;

4(x + y) = (10y + x) - 21 - - - (4)

Simplifying gives;

4x + 4y = 10y + x - 21

>> 10y - 4y - 4x + x = 21

>> 6y - 3x = 21 - - - (4)

Solving eq(3) and (4) simultaneously gives;

x = 5 and y = 3

Thus,

Original number = 53

Reversed number = 35

Difference between original and reversed number = 53 - 35 = 18
