Answer 1

Answer:

[tex][f(x)]^2-g(x) = 5x^2-13x-8[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 2x-2\\g(x) = -x^2+5x+12[/tex]

To find: [tex][f(x)]^2-g(x)[/tex]

First of all the square of first function f(x) will be found and then second function g(x) will be subtracted from the square of first function

Squaring the first function

[tex][f(x)]^2 = (2x-2)^2\\Using\ (a-b)^2 = a^2-2ab+b^2\\\[f(x)]^2 = (2x)^2-2(2x)(2)+(2)^2\\= 4x^2-8x+4[/tex]

Now subtracting g(x) from [f(x)]^2

[tex][f(x)]^2-g(x) = (4x^2-8x+4)-(-x^2+5x+12)\\\[f(x)]^2-g(x) = 4x^2-8x+4+x^2-5x-12[/tex]

Combining alike terms

[tex][f(x)]^2-g(x) = 4x^2+x^2-5x-8x+4-12\\\[f(x)]^2-g(x) = 5x^2-13x-8[/tex]

Hence,

Subtracting g(x) from the square of f(x) gives us:

[tex][f(x)]^2-g(x) = 5x^2-13x-8[/tex]

1. A newspaper headline claims: "Apple spends far less on Research & Development
than any of its rivals." Further into the story, the reporter writes that Apple spends a
paltry 2% of revenues compared with 14% at Google and Microsoft.
a. What is the mistaken assumption here?
b. Why is that assumption incorrect?
c. Is there a situation where the headline is still correct?

Answers

Answer:

Step-by-step explanation:

a)

The mistaken assumption is that Apple spends "far less" on Research and Development than any of its rivals.

b)

The assumption is incorrect because it took cognizance of the percentage used, and not the actual money spent. In truth, Apple generates far more income than the other two rivals. With Apple generating over $100bn in the said time span, and Google generating $37bn. At the end of the day, Apple spends $2.1bn on Research and Development, while Google spends $5.3bn on the same. This is quite close than the quoted distance of 14% - 2%

c)

Yes, I think so. But only when the 3 companies generate almost the same revenue.

Based on the description of the headline given in the scenario, the solution to the problems posed are :

A.)

The mistake in the assumption is that, the headline focused just on the percentage of the revenue made by each company that is spent on R&D.

B.)

The assumption is incorrect because, the revenue generated by the companies aren't the same. Hence, making comparison based on the percentage alone is incorrect.

C.)

The headline may be correct only when the revenue generated by each company is the same.

Answers

Answer:

The first angle is 68.

Step-by-step explanation:

[tex]x_{1}+x_{2}+x_{3}=180\\x_{1} = 4*x_{2}\\x_{3}=x_{2}+ 78\\4*x_{2} + x_{2} + x_{2}+ 78 = 180\\6*x_{2}=102\\x_{2} = 17\\[/tex]

So [tex]x_{1}=68[/tex] and [tex]x_{3}=95[/tex]

For the terms and like terms just put:

T:

LT:

Answers

Answer:

T: x^2 & 3 LT: -x & -3x

Step-by-step explanation:

x^2 has no other like term like: -x^2, 8x^2 or basically no longer "x^2"

3 is the same ^ there is no other single integer

(We cannot use -3x because it has an x attached to it)

-x & -3x are like terms because they both have an x to it a single x, not a x with an exponent like x^2

so -x + (-3x) would equal -4x if we wanted to solve it

Answer:

Terms: 3, (-x), x², (-3x)

Like terms: (-x) and (-3x)

Step-by-step explanation:

A term is a single number (positive or negative), a single variable (a letter), or several variables multiplied but not added or subtracted.

Like terms are terms that have the same variables and power like -x.

zach says that the expressions 6x - 36 and 3(2x -12) are equivalent

Answers

Answer:

True

Step-by-step explanation:

When you distribute the 3, you get x(2x3)-(12x3)

2x3=6

12x3=36

so 6x-36

and that is equivalent to the first expression.

The value 1 is a solution for x^2-6x+5=0
A. True
B. False

Answers

Answer:

The complex solution would be: X = 5,1

Step-by-step explanation:

Answer:

x=1

TRUE because Factoring  x2-6x+5

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  +5

Step-1 : Multiply the coefficient of the first term by the constant   1 • 5 = 5

Step-2 : Find two factors of  5  whose sum equals the coefficient of the middle term, which is   -6 .

     -5    +    -1    =    -6    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -5  and  -1

                    x2 - 5x - 1x - 5

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-5)

             Add up the last 2 terms, pulling out common factors :

                    1 • (x-5)

Step-5 : Add up the four terms of step 4 :

                   (x-1)  •  (x-5)

            Which is the desired factorization
