Given: y = 2x^2 - 32x + 56

1) y = 2 [ x^2 - 16x] + 56

2) y = 2 [ (x - 8)^2 - 64 ] + 56

3) y = 2 (x - 8)^2 - 128 + 56

4) y = 2 (x - 8)^2 - 72 <----------- answer

Minimum = vertex = (h,k) = (8, - 72)

=>  x-ccordinate of the minimum = 8 <-------- answer

Step-by-step explanation:

y = 2x^2-32x+56

y=2(x^2-16x+28)

Adding and subtracting 64 :

y=2(x^2-16x+64-64+28)[tex]y=2(x^2-16x+64) +2(-64+28)

y=2(x^2-2\times x\times 8+8^2) +2(-36)

Using identity : (a+b)^2=a^2-2ab+b^2

y=2\times (x-8)^2-72

y=2\times (x-8)^2+(-72)

Putting, x = 8

y=2\times (8-8)^2+(-72)

y = -72

Find the output, d, when the input, t, is 11. <br><br><br> d = -20+11t<br><br> d= __
mafiozo [28]
Substitute the given value into the equation


-20 + 11*11

Using BODMAS, you do 11*11 first, which is 121

Question 6(Multiple Choice Worth 1 points) (06.01 LC) Choose the correct classification of 5x + 2x2 − 8 by number of terms and b
Yakvenalex [24]

Question 7: Choose the correct simplification of the expression (3x − 6)(2x2 − 4x − 5)

Answer:

7. 6x³ - 12x² + 12x + 15

Step-by-step explanation:

(3x-6)(2x² - 4x - 5)

3x • 2x² = 6x³

3x • -4x = -12x²

3x • -5 = -15

-6 • 2x² = -12x²

-6 • -4x = 24x

-6 • -5 = 30

combine terms

6x³ - 12x² - 15 - 12x² + 24x + 30

combine like terms

6x³ - 24x² + 24x + 15

hope this helps :)

in the future, only ask one question per brainly submission. thanks!
