[tex](4 {x}^{2} - x + 3) - (3 {x}^{2} - 5x - 6) \\ = (4 - 3) {x}^{2} - (5 + 1)x + (3 - 6) \\ = {x}^{2} - 6x - 3[/tex]

a. -8/3 miles below sea level.

Sasha started at sea level and has hiked down to the fourth rest station.

Now sea level is 0.

Sasha takes a break at the rest stations every 2/3 of a mile.

This means she is down to 4 rest points means 4 times 2/3

This becomes =

But the answer will be in negative as she is below 0.

So, correct answer is: a. -8/3 miles below sea level.

                                       Other way,

sea level is 0.....so if u go below sea level, u will end up with a negative number...and since she is hiking down, ur answer will be negative. The is a station every 2/3 mile....and if she passed 4 of them....

-2/3 * 4 = - 8/3 <=== her elevation....another answer could have been - 2 2/3, but that is not there

Sasha's elevation will be -8/3 miles below sea level.

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that Sasha hikes into a canyon. She takes a break at the rest stations every 2/3 of a mile she descends.

Sasha started at sea level and hiked down to the fourth rest station. Now the sea level is 0. Sasha takes a break at the rest stations every 2/3 of a mile.

This means she is down to 4 rest points means 4 times 2/3

This becomes = 4 x ( 2 / 3) = 8 / 3

But the answer will be negative as she is below 0.

Therefore, Sasha's elevation will be -8/3 miles below sea level.

Answer: 1.6 lawns a week

Step-by-step explanation:

Carlt mowed 2 more lawns than Rocco every week for 5 weeks.

This means that the number of lawns he mowed more than Rocco is:

= 2 * 5

= 10 lawns

If Carlt mowed 18 lawns in those 5 weeks then Rocco mowed:

= 18 - 10

= 8 lawns

Lawns mowed per week by Rocco:

= 8/5

= 1.6 lawns a week

Answer:

400 meters

Step-by-step explanation:

Let X = unknown.

tan28 =X/750

0.5317= X/750

Cross multiply

0.5317×750= X

x = 398.775meters or 400( to the nearest whole number)

Answer:

[tex]f(x)\cdot g(x)=x^3-21x^2+135x-243[/tex]

Step-by-step explanation:

We are given the two functions:

[tex]f(x)=x^2-12x+27\text{ and } g(x)=x-9[/tex]

And we want to find:

[tex]f(x)\cdot g(x)[/tex]

So, by substitution:

[tex]=(x^2-12x+27)\cdot (x-9)[/tex]

Distribute:

[tex]=(x^2-12x+27)(x)+(x^2-12x+27)(-9)[/tex]

Multiply:

[tex]=(x^3-12x^2+27x)+(-9x^2+108x-243)[/tex]

Rearrange:

[tex]=(x^3)+(-12x^2-9x^2)+(27x+108x)+(-243)[/tex]

Combine like terms:

[tex]=x^3-21x^2+135x-243[/tex]

Hence:

[tex]f(x)\cdot g(x)=x^3-21x^2+135x-243[/tex]

BAD  QUESTION.

Believe it's y = 4x + 40 and y = 40. Others don't make sense. Sorry for bad explanation, but I'm a little unsure do to the question...

The second one is probably x > 10

Answer:

We conclude that 49x² - 28x + 4 = 0 has only one real root.

Thus, option B i.e. one real root is the correct option.

Step-by-step explanation:

Given the equation

49x² - 28x + 4 = 0

comparing with the quadratic equation ax² + bx + c = 0 for x, where a ≠ 0,

here

a = 49, b = -28, c = 4

Determining the discriminant b²-4ac

b²-4ac = (-28)² - 4(49)(4)

           = 784 - 784

           = 0

It is clear that the discriminant b²-4ac is equal to zero.

i.e.

b²-4ac = 0

We know that if the discriminant b²-4ac = 0, then the quadratic equation has one real root.

Therefore, we conclude that 49x² - 28x + 4 = 0 has only one real root.

Thus, option B i.e. one real root is the correct option.
