A parabola has vertex (4, 3) and one of x-intercept is 1, find the other x-intercept. If the function y = reaches the minimum value at point x = a, and the minimum value is m. Find the value of a + m.

Parabola y = − 8x + 15 has two intersection points with x-axis: A and B, it intersects y-axis at point C. Find the area of ΔABC

40 minutes

step-by-step explanation:

add the time and multiply by 2

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
