Answer 1
For f(x), 6 represents x here, so we plug 6 in for x to get 2*6²+5√(6-2). Using PEMDAS, we get 72+5√4=72+5*2=72+10=82

Determine the nature of the roots of the function
f(x)=7x^2+5x-1

Answers

Finding the values of the discriminant:-

b^2 - 4ac  = 5^2 - 4*7 * -1  =  25 + 28  = 53

There will be 2 real roots 

Final answer:

To determine the nature of the roots of the function f(x)=7x²+5x-1, we calculate the discriminant, which is 53. Since it's positive, the equation has two distinct real roots.

Explanation:

The nature of the roots of the quadratic function f(x)=7x²+5x-1 can be determined by calculating the discriminant, which is part of the quadratic formula. The discriminant is given by b² - 4ac, where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0. For the given function, a = 7, b = 5, and c = -1. Therefore, the discriminant equals:

D = b² - 4ac

D = (5)² - 4(7)(-1)

D = 25 + 28

D = 53

Since the discriminant is positive (D > 0), the quadratic function has two distinct real roots.

What is y=-4x-15 in standard form

Answers

y=-4x-15
4x + y = -15 ...this is standard form

hope it helps

Final answer:

To convert the equation y = -4x - 15 to standard form, you add 4x to both sides to get 4x + y = -15, which aligns with the standard form Ax + By = C.

Explanation:

To convert the equation y = -4x - 15 into standard form, we need to rearrange it such that the x- and y-terms are on one side of the equation and the constant is on the other side, typically with the x term first. The standard form of a linear equation is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

The given equation is already close to this form, but we need to get the x-term to the other side of the equation. To do this, we simply add 4x to both sides, giving us:

4x + y = -15

This is the standard form of the given linear equation.

Y2 + 30 ÷ x - 8 what is the value of the expression when x = 6 and y = 8?

Answers

Assuming that by Y2 you mean 2 * Y (I'd suggest flipping them for organizational purposes), you'd just plug in for the values. 

So 2(8) + 30 ÷ 6 - 8. PEMDAS says we do the multiplication and division first. 
This gives us 16 + 5 - 8 = 13. 

Again assuming Y2 means 2 * Y in your equation, the answer is 13. 
Y2 + 30 ÷ x - 8  i think this y power 2 ??

8 power 2   + 30 ÷  6  -  8  =

64  + 30 ÷  6  -  8  = 

64 +5-  8 =  61 

we use first the power then the multiplication or division and the last addition and subtraction 

Please help me solve this equation but show the steps so I can learn how to solve it.

A farmer drives a tractor from one town to another, a distance of 120 kilometers. He drives 10 kilometers per hour fast on the return trip, cutting an hour off the time. How fast does he drive each way?

Answers

120/x - 120/(x+10) = 1
120x + 1200 - 120x = x(x+10)
1200 = x^2+10x
x^2 + 10x - 1200 = 0
(x+40)(x-30) = 0
Positive solution:
x = 30 km/hr (rate on the 1st trip)
x+10 = 40 km/hr (rate on the return trip)

How many real solutions does the equation 0.2x^5-2x^3+1.8x+k=0 have when k = 0?

Answers

when k =  we have:-

0.2x^5 - 2x^3 + 1.8x = 0

so x = 0 is one solution 

taking 0.2x out we have:-
0.2x( x^4 - 10x^2 + 9x) = 0

factoring::-

(x^2 - 9)(x^2 - 1) = 0

this  gives x = +/= 3  and x = +/- 1

so there are 5 real solutions

For spring break you and some friends plan a road trip to a sunny destination that is 1705 miles away. if you drive a car that gets 39 miles per gallon and gas costs $3.339/gal, about how much will it cost to get to your destination?

Answers

1705/39 = 43.718 gallons
43.718*3.339 = $145.97 

Answer:

$145.98

Step-by-step explanation:

You and some friends plan a road trip to a sunny destination that is 1705 miles away.

You drive a car that gets 39 miles per gallon.

Total gas used in the trip = [tex]\frac{1705}{39}[/tex]

                                          = 43.7179487 ≈ 43.72 gallons

Gas costs per gallon = $3.339

Total cost to get to your destination = 43.72 × 3.339

                                                            = $145.98108 ≈ $145.98

The cost would be $145.98 to get to your destination.

Rename 12,000 ten thousand

Answers

120,000 or twelve thousand 10,000
Final answer:

Renaming 12,000 as 'ten thousand' means expressing it as '1 ten thousand and 2 thousand'. This breaks the number down into units of ten thousand, with 10,000 being the base unit and the additional 2,000 making up the rest.

Explanation:

The phrase 'rename 12,000 ten thousand' refers to the process of expressing the number 12,000 in terms of ten thousand. To do this, we need to understand that the number 10,000 is a base unit in this context, acting as one 'ten thousand'. Therefore, the number 12,000 would be considered as 1 ten thousand and 2 thousand, since 12,000 is made up of one 10,000 and an additional 2,000 units.

To better understand, let's do a breakdown:

10,000 (one ten thousand) + 2,000 (two thousand) = 12,000

We know that:

10,000 is one ten thousand.20,000 is two ten thousands.30,000 is three ten thousands.And so on, up to 160,000, which would be sixteen ten thousands.

In this case, when we want to 'rename' 12,000 as ten thousand, it becomes 1 ten thousand and 2 thousand.

PLZ HELP Simplify the rational expression. State any excluded values. 2x/-5x+x^2

Step-by-step explanation:

Given : Expression  [tex]\frac{2x}{-5x+x^2}[/tex]

To find : Simplify the rational expression. State any excluded values.      

Solution :

First we simplify the expression,

[tex]\frac{2x}{-5x+x^2}[/tex]

Taking x common from the denominator,

[tex]=\frac{2x}{x(-5+x)}[/tex]

Cancel the common term from numerator and denominator,

[tex]=\frac{2}{-5+x}[/tex]

To find the excluded value we put the denominator equal to zero to get the value of x in which given expression is not valid.

[tex]-5+x=0[/tex]

[tex]x=5[/tex]

Therefore, The excluded value is x=5.

A rectangle patio is surrounded on three sides by a fence. If the areas of the patio is 45 m sq and the total of fence is 19m what is the length and width of the patio?

Answers

LW = 45
L + 2W = 19
L = 19-2W

substituting for L :-
W(19-2W) = 45

-2W^2 + 19W = 45

2W^2 - 19W + 45 = 0 
W = 5 or 4.5

If W = 5, L = 9
If W = 4.5, L = 10

So there are 2 possible answers.

Solve for x. Show each step of the solution. 4.5(8−)+36=102−2.5(3+24) i need to show my work dont just give me the answer

Answers

4.5 * (8-) + 36 = 102 - 2.5 * 27
4.5 * 8 - 36 = 102 - 2.5 * 27
36 - 36 = 102 - 2.5 * 27
36 - 36 = 102 - 67.5
36 - 36 = 34.5
Since we know 36 - 36 doesn't equal 34.5 its not true so there is NO ANSWER.
4.5(8 - x) + 36 = 102 - 2.5(3x + 24)

36 - 4.5x + 36 = 102 - 7.5x - 60

-4.5x + 72  = 42 - 7.5x

I think C because parallel lines would have the same gradient or slope. If they were perpendicular the product of their slopes would be -1. Also parallel lines don’t intercept one another, but these equations can be solved for unique x and y which is their point of intersection.

Which type of question fits a binomial model? A. fill in the blank B. matching C. multiple choice D. true/false

Answers

The answer would be C. Hope this helped!
Final answer:

The type of question that fits a binomial model is a true/false question, as this type of question strictly limits the outcome to two possibilities - correct or incorrect.

Explanation:

The type of question that fits into a binomial model would be a true/false question. A binomial distribution, in mathematics and statistics, is used to model a number of successes in a sequence of independent and identically distributed binary experiments, such as flipping a coin or indeed, answering a true/false question. These types of questions are considered binomial because there are two possible outcomes: right or wrong, true or false. On the other hand, options like 'fill in the blank', 'matching', or 'multiple choice' doesn't fit the binomial model because they do not strictly limit the outcome to two possibilities.

(1) Sometimes they sat down on the sea, near patches of brown seaweed that rolled on the waves with a movement like carpets on a line in a gale. The birds sat comfortably in groups, and they were envied by some in the dingey, for the wrath of the sea was no more to them than it was to a covey of prairie chickens a thousand miles inland. (2) Often they came very close and stared at the men with black bead-like eyes. At these times they were uncanny and sinister in their unblinking scrutiny, and the men hooted angrily at them, telling them to be gone. One came, and evidently decided to alight on the top of the captain's head. (3) The bird flew parallel to the boat and did not circle, but made short sidelong jumps in the air in chicken-fashion. His black eyes were wistfully fixed upon the captain's head. "Ugly brute," said the oiler to the bird. "You look as if you were made with a jack-knife." The cook and the correspondent swore darkly at the creature. (4) The captain naturally wished to knock it away with the end of the heavy painter; but he did not dare do it, because anything resembling an emphatic gesture would have capsized this freighted boat, and so with his open hand, the captain gently and carefully waved the gull away. (5) After it had been discouraged from the pursuit the captain breathed easier on account of his hair, and others breathed easier because the bird struck their minds at this time as being somehow grewsome and ominous. a :Sentence 1 b :Sentence 2 c :Sentence 3 d :Sentence 4 e :Sentence 5 what were the monsters of seemingly paradise like panama?
