Describe the solution of f(x) shown in the graph.


a parabola opening up passing through 0 comma 2, 1 comma zero and 2 comma zero


All real solutions

All solutions that lie on f(x)

All positive solutions

All whole number solutions

pls answer fast!

Answers

Answer:

C. All positive solutions

Step-by-step explanation:

We can see that the solutions (or points that intercept the x-axis) are at 0,1 and 0,2. We can simplify this to just 1,2 if you would like, but nevertheless all x-intercepts are positive.

x = 1 and x = 2 are the solutions of the parabola shown.

All whole number and positive solutions.

Options C and D are correct.

How do you find the opening of a parabola?

There is an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.

When we are looking for a solution to a graphical function f(x), we basically mean the x-intercepts of the graph.

The place where the graph cuts/crosses the x-axis are the solutions of the graph. The y point will always be 0 at those designated x values.

Looking at the graph, we see that:

x = 1 and x = 2

are the solutions of the parabola shown.

All whole number and positive solutions.

Options C and D are correct.

Geoffrey wants to make one planter that extends from the ground to just below his back window. The window starts 3 feet off the ground. If he wants the planter to hold 36 cubic feet of soil, name one way he could build the planter so it is not taller than 3 feet. Explain how you know.

Answers

Answer:

Step-by-step explanation:

36 / 3 = 12

12 = 4 x 3

V = L x W x H

= 4ft x 3ft x 3ft

=

Since Geoffrey wants to build a planter with a height of 3ft & a volume of 36ft^(3), the base of the planter should have an area of 12ft^(2).

Answers

Answer:

see below

Step-by-step explanation:

a. -11r ≥ 220

Divide both sides by -11 to isolate r.

r ≥ -20

b.

-8 ≤ -7 + (x/10)

Add 7 to both sides.

-1 ≤ x/10

Multiply both sides by 10 to cancel out the denominator of x.

-10 ≤ x

c. -1 - 6(5q - 2) ≥ -139

Distribute the -6 across the parentheses.

-1 - 30q + 12 ≥ -139

Combine like terms on the left side.

-30q + 11 ≥ -139

Subtract 11 from both sides.

-30q ≥ -150

Divide both sides by -30 to isolate q.

q ≥ 5

Hope this helps!

-11r>=220

divide both sides by -11
since both sides are divided, flip the sign

r<=-20
r is less than or equal to negative twenty

The cube volume is 1000cm find the all face area
A. 200cm
B. 300cm
C. 500cm
D. 600cm

Answers

Answer:

D. 600 [tex]cm^{2}[/tex]

Step-by-step explanation:

Volume of a cube = [tex]s^{3}[/tex] = 1000, s = [tex]\sqrt[3]{1000} =10[/tex]

So, the side length is 10 cm

Surface area of a cube is 6[tex]s^{2}[/tex] where s is the side length

so [tex]s^{2}[/tex] = [tex]10cm^{2} = 100 cm^2[/tex]

6*100[tex]cm^{2}[/tex] = 600 [tex]cm^{2}[/tex]

So the answer is D. 600 cm (it should have a little superscript 2 next to it)

area= D. 600cm (centimeters)

Answers

The answer would be the third option or C

Answer:

C: √74

Step-by-step explanation:

We have to use the Pythagorean theorem to answer this (a² + b² + c²). We have a and b so all we have to do is square 5 and 7 (a and b) so we get a² b², then we add this to get c² as stated by the Pythagorean theorem. So, 7² (7 x 7) is 49, and 5² (5 x 5) is 25. 25+49 (a² + b²) is 74 (c²). So the square root of this would be the absolute length of the hypotenuse because this is the hypotenuse squared. Meaning that the answer would be √74 (square root of 74)

2(3x – 5) = 8
what is the x?

Answers

Answer:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2*(3*x-5)-(8)=0

2 • (3x - 5) -  8  = 0

Pull out like factors :

6x - 18  =   6 • (x - 3)

6 • (x - 3)  = 0

Solve :    6   =  0

Add  3  to both sides of the equation :  

x = 3

Answer: x = 3

Step-by-step explanation:

2(3x-5)=8

first, you multiply 2 by 3x and -5.

6x-10=8

since we want 6x by it’s self we add 10 to its self and add it to 8 as well.

6x = 18

now we divide 6 to both 6x and 18.

x = 3

Taylor emptied out her change jar to buy a new soccer ball for practice. The jar contained 128 coins consisting of quarters and dimes that totaled $25.10. Which system of equations could be used to determine how many quarters, q, and how many dimes, d, Taylor had in her change jar?

Answers

Answer:

.25q+.10d=25.10

q+d=128

Step-by-step explanation:

Since a quarter is 25 cents and a dime is 10 cents that is how you figure out your first equation. You set it equal to 25.10 because that is the amount of money it totals to. The second equation (q+d=128) is used because the amount of quarters plus dimes needs to make 128.

Let q be the no. of quarters and d be the no. of dimes.

q+d=128
25q+10d=2510

These are the system of equations. To solve it, we do this:

q=128-d
25(128-d)+10d=2510
3200-25d+10d=2510
15d=690
d=46
q=128-46=82

Think of people among your family, your friends, or your classmates who are relatively unequal in terms of wealth. What is their relationship like? What factors come into play? Beagles, greyhounds, German shepherds, and even tiny toy poodles are all related to the same majestic wild animal, the wolf. In fact, all domestic dogs are descended from wolves. There are several species of wolf, including the gray wolf, the arctic wolf, the red wolf, the white wolf, and the Mexican wolf. Wolves are some of the most widespread mammals. Populations of wolves exist in almost as many places around the globe as humans do.Wolves are exceptional pack hunters. This is why they are able to take down large prey such as moose or deer by working together as a seamless team. Wolf pups as young as eight months old begin helping on the hunt. Wolves can reach speeds of up to 40 miles per hour when chasing prey, and their thick, double-coated fur enables them to keep warm in even the coldest arctic temperatures. Their large, powerful paws can reach up to 5 inches across and help to propel them quickly across the snow.Next time you're playing fetch with your furry friend, think about its ancestor, the wolf. That terrier or pug might only be able to take down a ball or a bone, but it gained its instincts to chase and hunt from those greatest of hunters, the wolves.Read the article "The Necessity of Hybrids".What do you get if you cross two different species? Depending upon the species, you might end up with a grolar bear, a wolfdog, or a Savannah cat, among many others. What do these animals have in common? They're hybrids. Sometimes hybrids happen naturally in the wild, but usually, hybrids are the result of humans selectively breeding animals.Grolar bears and pizzlies are the result of crossing polar bears and grizzly bears. These hybrids were first seen in zoos, as the bears' natural habitats did not normally overlap. Recently, these hybrids have started appearing in the wild. Due to climate change, the bears' once-separate habitats are beginning to overlap. Bigger and more aggressive than their parents, grolar bears and pizzlies could pose a risk to natural habitats and humans.Wolfdogs are, as their name suggests, the result of crossing a wolf with a domestic dog. Bred for the pet trade, these hybrids do not often happen in the wild. Wolfdogs do not make good pets, however, as they can be destructive and aggressive. Many states have outlawed keeping wolfdogs because they can pose a danger to people.Savannah cats are another example of human-made hybrids that were developed to be pets. Savannahs are the result of crossing a small wildcat called a serval with a domestic housecat. They look like miniature versions of the wildcat, which is why many people like keeping them as pets. Like the wolfdog, however, Savannahs do not make ideal house pets. They can be destructive, and usually, they keep the wild nature of the serval.There are many more examples of human-made hybrid animals. Some hybrids, such as the mule, have been helpful to humans. Unfortunately, others, like the wolfdog or Savannah cat, should not have been made in the first place.How is the overall structure of "The Wolves Among Us" similar to the structure of "The Necessity of Hybrids"?A.
