1.6i+3/4d-3(1/2i-1.1d)-4.2
Scrat [10]

Answer:

4.05d+0.1i−4.2

Step-by-step explanation:

Let's simplify step-by-step.

1.6i+ 3/ 4 d−3( 1 /2 i−1.1d)−4.2

Distribute:

=1.6i+ 3/ 4 d+(−3)( 1/ 2 i)+(−3)(−1.1d)+−4.2

=1.6i+ 3/ 4 d+ −3/ 2 i+3.3d+−4.2

Combine Like Terms:

=1.6i+ 3/ 4 d+ −3/ 2 i+3.3d+−4.2

=( 3/ 4 d+3.3d)+(1.6i+ −3/ 2 i)+(−4.2)

=4.05d+0.1i+−4.2

Hope it helped!

Find the vertex : f(x)=3x^2-18x+10
Vlad [161]

f(x)=3x^2-18x+10

a = 3, b = -18 and c = 10

The vertex of a parabola is in form a(x+d)^2 + e

d = b/2a = -18/2(3) = -18/6 = -3

e = c-b^2/4a = 10 - -18^2/4(3) = 10-27 = -17

Now the vertex form of the parabola becomes 3(x-3)^2 -17

Use the vertex form of the parabola in the vertex form of y = a(x-h)^2 +k

Where a = 3, h = -3 and k = -17

Now you have y = 3(x-(-3))^2 +(-17)

Simplify: y = 3(x+3)^2 -17

The vertex becomes the h and k values of (3,-17)
