The vertex of a quadratic function is located at (1, 4), and the y-intercept of the function is (0, 1). What is the value of a i

Setler [38]

Answer:

The value of a is $-3$

The equation is $y=-3(x-1)^{2}+4$

Step-by-step explanation:

we know that

The function of a vertical parabola written in vertex form is equal to

$y=a(x-h)^{2}+k$

where

(h,k) is the vertex of the parabola

in this problem we have

$(h,k)=(1,4)$

substitute in the equation

$y=a(x-1)^{2}+4$

Find the value of the coefficient a

Substitute the value of x and y of the point $(0,1)$ in the equation

$1=a(0-1)^{2}+4$

$1=a(-1)^{2}+4$

$1=a+4$

$a=-3$

The equation is equal to

$y=-3(x-1)^{2}+4$ ----> is a vertical parabola open downward

125% of what number is 25

Mazyrski [523]

We can create a equation to find out.

since we are finding a number where when multiplied by 1.25(this is the decimal form of the percentage) gives us 25, we know that the number we are finding is less than 25. here is the equation.

1.25(x)=25

divide both sides by 1.25 to get "x" alone.

x= 20
