Describe the translation. y=(x+3)2+4 → y=(x+1)2+6

Answers

Answer:

Shift +2 units to the right and +2 units up

Step-by-step explanation:

y = (x+3)² + 4 has a horizontal shift of -3 and a vertical shift of +4.

y = (x+1)² + 6 has a horizontal shift of -1 and a vertical shift of +6.

So do translate the first equation to the second, shift +2 units to the right and +2 units up.

Find the value of z

Answers

Answer:

C. 50

Step-by-step explanation:

We are given ΔABC with an altitude BD as shown in the figure.

As it is known that,

'When an altitude is drawn from a right angle of a triangle, then all the three triangles are congruent.'

So, we get that ΔABC ≅ ΔABD ≅ CBD.

Since, the triangles are congruent, their corresponding sides and angles will be congruent.

Moreover, the ratio of the sides will be equal.

So, we get from ΔABC ≅ ΔABD,

(AD)/(AB)=(AB)/(AC)

i.e. AD=(AB* AB)/(AC)

i.e. 18=(30* 30)/(z)

i.e. 18=(900)/(z)

i.e. z=(900)/(18)

i.e. z = 50.

Hence, the value of z is 50.
