Cut it into 3 shapes, the bottom half circle, the top rectangle, and the middle rectangle

top rectangle:

A= bh

A= 4x10

A=40

middle rectangle:

A=bh

A=4x7

A= 28

Half circle:

A= πxr^2

A=πx6x6

A=πx36

A=56.52

Find the zeros of y = x2 – 6x – 4 by completing the square.

katrin [286]

Answer:

The solutions to the quadratic equations are:

$x=\sqrt{13}+3,\:x=-\sqrt{13}+3$

Step-by-step explanation:

Given the function

$y\:=\:x^2\:-\:6x\:-\:4$

substitute y = 0 in the equation to determine the zeros

$0\:=\:x^2\:-\:6x\:-\:4$

Switch sides

$x^2-6x-4=0$

Add 4 to both sides

$x^2-6x-4+4=0+4$

Simplify

$x^2-6x=4$

Rewrite in the form (x+a)² = b

But, in order to rewrite in the form x²+2ax+a²

Solve for 'a'

2ax = -6x

a = -3

so add a² = (-3)² to both sides

$x^2-6x+\left(-3\right)^2=4+\left(-3\right)^2$

$x^2-6x+\left(-3\right)^2=13$

Apply perfect square formula: (a-b)² = a²-2ab+b²

$\left(x-3\right)^2=13$

$\mathrm{For\:}f^2\left(x\right)=a\mathrm{\:the\:solutions\:are\:}f\left(x\right)=\sqrt{a},\:-\sqrt{a}$

solve

$x-3=\sqrt{13}$

Add 3 to both sides

$x-3+3=\sqrt{13}+3$

Simplify

$x=\sqrt{13}+3$

now solving

$x-3=-\sqrt{13}$

Add 3 to both sides

$x-3+3=-\sqrt{13}+3$

Simplify

$x=-\sqrt{13}+3$

Thus, the solutions to the quadratic equations are:

$x=\sqrt{13}+3,\:x=-\sqrt{13}+3$

PLEASE MAKE SURE YOU GIVE WORKING AND AN EXPLANATION FOR YOUR ANSWER Question) The sum of the integers from -2015 to 2017 is (A)

yKpoI14uk [10]

Answer: (A) 2

The sum of the integers from -2015 to 2017 = 2

Step-by-step explanation:

The sum of integers a and b is represented as a+b.

The sum of the integers from -2015 to 2017 = -2015+2017

Since -a+b=b-a

Thus, The sum of the integers from -2015 to 2017 = 2017-2015 = 2

i.e. The sum of the integers from -2015 to 2017 = 2

Thus , the correct option is (A).
