Answer:
The equation of the quadratic function shown is;
x^2+ 2x -3
Step-by-step explanation:
Here in this question, we need to know the quadratic equation whose graph was shown.
The key to answering this lies in knowing the roots of the equation.
The roots of the equation are the solution to the quadratic equation and can be seen from the graph at the point where the quadratic equation crosses the x-axis.
The graph crosses the x-axis at two points.
These are at the points x = -3 and x = 1
So what we have are;
x + 3 and x -1
Multiplying both will give us the quadratic equation we are looking for.
(x + 3)(x-1) = x(x -1) + 3(x-1)
= x^2 -x + 3x -3 = x^2 + 2x -3
Answer:
75.00
Step-by-step explanation:
1500*0.05
because 5% is her interest you convert 5% into a decimal = 0.05
then you multiply 1500 by 0.05 and you get 75.00
For a 30 sided regular polygon, We can divide the polygon (30 sides) into 30 inscribed triangles with central vertex angles of = 
.
This central vertex angle of <u>12 degrees</u> is the degree of rotation for a 30 sided polygon.
In other words, the 30 sided polygon has <u>12 degree</u> rotational symmetry about the center.
Answer:
Center (6 , -5) and radius = 3
Step-by-step explanation:
The Standard equation of circle can be written as
(x - a)² + (y - b)² = r²
with center (a , b) and radius = r
Now from given circle equation
(x - 6)² + (y +5)² = 9
so, from here center of circle (6 , -5) and radius = 3
