, 0).

The positive x-intercept is at (
, 0).


Answers

Answer 1

Answer:

The negative x-intercept is at (-1/3,0)

The positive x-intercept is at (4,0)

Explanation:

Answer 2

Answer:

The negative x-intercept is at (-1/3 , 0).

The positive x-intercept is at (4 , 0).

Explanation:

Where does f(x) = 3x2 – 11x – 4 intersect the x-axis?

The negative x-intercept is at (-1/3 , 0).

The positive x-intercept is at (4 , 0).

Set f(x) equal to zero so

3x2 – 11x – 4 = 0

Plug in a. b, and c into the quadratic formula

and get 2 solutions:

1/3 and -4

take the opposite signs and put it in the x intercepts

State reason(s) why ash should or should not be used in making compost

Answers

Answer:

Fireplace ashes for compost can be used to help maintain the neutral condition of the compost. It can also add nutrients to the soil. Decomposing materials in the compost pile can become somewhat acidic and wood ash can help offset this, as it's more alkaline in nature.  But Adding too much ash to the pile can be detrimental to the makeup of the compost because of its alkalinity. Ashes tend to raise the soil pH, so you shouldn't use it directly on plants, especially acid-loving ones like rhododendrons, azaleas, and blueberries. Also, in high amounts, wood ash can inhibit plant growth by restricting nutrients, like iron.

Predict how a loss of function mutation in the p53 gene is most likely to affect the cell cycle in response to DNA damage. Justify your predictions.

Answers

Answer:

The cell cycle of cell multiplication is regulated by three types of genes, the regulatory genes that control mutations, the generic promoters of cell replication, and genes that inhibit cell replication.

The balance between these three types of gene group are what result in a good multiplication of cells without mutations or neoplastic developments.

The p53 gene is one of the genes that is considered as the guardians of the genome, since it is in charge of corroborating and regulating mutated cells, in this way it inhibits their progression in the cell cycle by putting a stop to not replicate defective genes or genes with alterations.

Explanation:

The p53 gene is one of the most altered genes seen in malignant neoplasms, since by altering our guardian of the genome many mutations overlook and more carcinogenic potential will have neoplastic tissue.

In the three groups of genes that we write, all three have a fundamental roll in the cell cycle, but in order to trigger malignant neoplasms, it is necessary that there be a continuous series of gene mutations in these three groups, it is not enough with the mutation of a single gen.

Line t passes through (4, 5) and is perpendicular to the line shown on the coordinate grid.

a coordinate plane with a line passing through two points at 0 comma 3 and 7 comma 2

What is the equation of line t in standard form?

x − 7y = −161
7x − y = 23
−7x − y = 23
x + 7y = 161

Answers

Answer:

it is b

Explanation:

The equation of line t is [tex]7x-y=23[/tex]

Equation of line :

Given that , A line passing through two points [tex](0,3),(7,2)[/tex]

Slope of line is,

                   [tex]m=\frac{2-3}{7-0}=-\frac{1}{7}[/tex]

Since, line [tex]t[/tex] and given line are perpendicular to each other.

Slope of line [tex]t[/tex] is, [tex]=7[/tex]

Equation of line [tex]t[/tex] is, [tex]y=7x+c[/tex]

Line [tex]t[/tex] passes through [tex](4, 5)[/tex]

Substitute point in equation of line [tex]t[/tex].

A new type of fish has been discovered. It has vibration receptors on its snout and virtually nonexistent eyes. Based on these characteristics, in which part of the ocean is this fish most likely found?

Answers

the bottom of the ocean

If a fish has vibration receptors on its snout and virtually nonexistent eyes, these characteristics are found in the fish which leaves at the bottom of the ocean.

What is the use of receptors on fish?

It is found under the skin, the lateral line made of sensory receptors known as neuromasts. While the cilia in the neuromasts vibrate, the fish can sense.

The lateral line may likewise feel and observe water pressure (depth), currents, objects, prey, and predator movements,  this senses increase the chance for the survival of the fish.

Food and lure that is living and moving would be simple for fish to detect as it has a smell, sound and vibration.

Therefore, with vibration receptors, at the bottom of the ocean, this kind of fish generally found.
