I need some help with this(ratio)(need explanation)

The roots of an equation are simply the x-intercepts of the equation.

See below for the proof that [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex] has at least two real roots

The equation is given as: [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex]

There are several ways to show that an equation has real roots, one of these ways is by using graphs.

See attachment for the graph of [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex]

Next, we count the x-intercepts of the graph (i.e. the points where the equation crosses the x-axis)

From the attached graph, we can see that [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex] crosses the x-axis at approximately -2000 and 2000 between the domain -2500 and 2500

This means that [tex]\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}[/tex] has at least two real roots

Answer: 3/4 difference

Step-by-step explanation:

Turn 1 1/2 improper = 3/2

(2 · 10) + (2 · 12)

Step-by-step explanation:

20 + 24

= (2 · 10) + (2 · 12)

proof :

20 + 24 = 44

(2 · 10) + (2 · 12)

= 2(10 + 12)

= 2(22)

= 44

Answer:

  a^2b^5

Step-by-step explanation:

Anything divided by itself is 1.

That is, anything multiplied by its reciprocal is 1. This value (the reciprocal of the expression) is called the "multiplicative inverse." Its value is that the product of an expression and its multiplicative inverse is 1, the multiplicative identity element. (Anything times 1 is itself.)

So, to get 1 as a product, multiply by 1/(a^2b^5), which is to say, divide by a^2b^5 to get 1 as a quotient.

Answer: 6 tablets.

Given:

• A certain medication is available only in 400 μg tablets.

So, in milligrams :- 0.4 mg

• It is also given that the patient needs to take 2.4 mg per day.

Solution:

So, in order to know how many tablets she should take, please do as following:-

[tex] \frac{2.4}{0.4} [/tex]

[tex] = > \: 6[/tex]

Hence, she must take 6 tablets per day.

Answer:

[tex]h=4[/tex]

Step-by-step explanation:

We know that the vertex(lowest point) of [tex]|x-h|[/tex] is [tex](h, 0)[/tex].

By inspection, we can see that the vertex of the graph is [tex](4, 0)[/tex].

So, the lowest point of [tex]F(x)=|x-h|[/tex] is [tex](4, 0)[/tex], which means [tex]\boxed{h=4}[/tex]

Answer:

Step-by-step explanation:

0=|x-h|

x=h,

but y=0 when x=4

so h=4

Step-by-step explanation:

[tex]2x - 10 + 4x + 16 = 180 \\ \\ 4x - 2x + 16 + 10 = 180 \\ \\ 2x = 180 - 26 \\ \\ 2x = 154 \\ \\ x = \frac{154}{2} \\ \\ x = 77[/tex]

Answer:

From the above attachment we can conclude that,

[tex](2x - 10)° + (4x + 16)° = 180° \\ 2x - 10 + 4x + 16 = 180 \\ 2x + 4x - 10 + 16 = 180 \\ 6x + 6 = 180 \\ 6x = 180 - 6 \\ 6x = 174 \\x = \frac{174}{6} \\ \boxed{x = 29}[/tex]

Therefore, the value of x is 29

Answer:

  Yes, Yolanda bought enough

Step-by-step explanation:

a. Read and understand the question, including what is given and what is asked for. Here, we have ...

  Given: mixed nuts $6.75 per pound, $21.60 spent on mixed nuts; dried fruit $4.25 per pound, $11.90 spent on dried fruit.

  Find: is the total weight of purchased mixed nuts and dried fruit at least 6 pounds?

__

b. Select appropriate relations to create a path from what is given to what is asked for. Here, we have ...

  weight = cost/(cost per pound)

  total weight = weight of mixed nuts + weight of dried fruit

__

c. Use the relations with the given information to come to a conclusion that will answer the question.

  weight of mixed nuts = $21.60/($6.75/lb) = 3.2 lb

  weight of dried fruit = $11.90/($4.25/lb) = 2.8 lb

  total weight = (3.2 lb) +(2.8 lb) = 6.0 lb

Yolanda wanted to buy a total of 6 pounds for the party, and she bought 6 pounds. Yolanda bought enough for the party.
