Which inequality is shown in this graph?
A. ys 2x - 2
B. y2-2x-2
C. yz 2x-2
D. ys-2x-2
Answers
Answer:
D
Step-by-step explanation:
when graphing inequalities if the shaded region is below the line then it is less than. Solid line makes it equal to. Line is going downwards so slope is negative. y intercept is in the negative region.
The inequality which is shown in this graph is y ≥ 2x - 2, the correct option is C.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
An inequality is a mathematical statement that compares two values or expressions using a relational operator, such as less than (<), greater than (>), less than or equal to (≤), greater than or equal to (≥), or not equal to (≠). Inequalities are used to describe relationships between quantities or to express constraints or conditions.
We are given that;
The graph
Now,
The inequality that is shown in this graph is C. y ≥ 2x - 2. This is because the graph shows a solid line with a slope of 2 and a y-intercept of -2, which is the equation y = 2x - 2. The solid line means that the points on the line are included in the solution set of the inequality. The shaded region above the line means that the points in that region satisfy the inequality.
Therefore, by the inequality the answer will be y ≥ 2x - 2.

The dimensions of the second drawing will be 2 1/2 the dimensions of the leaf. If the oak leaf is 5 1/2 inches, will the length of each drawing be equal to, greater then, or less than 5 1/2 inches?
Answers
Answer: See explanation
Step-by-step explanation:
The dimensions of the first drawing will be 1/3 the dimensions of the leaf and the dimension of the oak leaf is 5 1/2 inches. Therefore, the dimensions of the 1st leaf:
= 1/3 × 5 1/2
= 1/3 × 11/2
= 11/6
= 1 5/6 inches
This is less than 5 1/2 inches
The dimensions of the second drawing will be 2 1/2 the dimensions of the leaf. This will be:
= 2 1/2 × 5 1/2
= 5/2 × 11/2
= 55/4
= 13 3/4 inches
Thus is greater than 5 1/2 inches

[Function Composition] could someone help me with this answers or show work either is fine
Answers
Answer:
The required answer is 100 .
Step-by-step explanation:
Given function to us is ,
⇒ f(n) = 4n + 2 . And we need to find (f • f) (-3)
So , first let's find f•f , which will be ,
⇒ (f • f) = (4n + 2)(4n + 2)
⇒ (f • f) = 4n ( 4n + 2 ) +2 ( 4n + 2)
⇒ (f • f) = 16n² + 8n + 8n + 4
⇒ (f • f) = 16n² + 16n + 4
====================================
Now we need to find (f • f)(-3) . So on substituting f = (-3) , we have :-
⇒ (f • f)(n) = 16n² + 16n + 4
⇒ (f • f)(-3) = 16*(-3)² + 16*(-3) + 4
⇒ (f • f) (-3) = 16* 9 - 48 + 4
⇒ (f • f)(-3) = 144 - 44
⇒ ( f • f) (-3) = 100
Hence the value of ( f • f)(-3) is 100 .The area of the rectangle is 34 square meters. Find the length and the width.

Lexi say that -68 feet is a greater depth than- 75 feet, since-68>-75. Is Lexi correct? Explain
Answers
Answer:
No
Step-by-step explanation:
When working with negative numbers in terms of depth, greater depth are depicted by values as we move farther to the left of the number line.
With this in mind, - 75 feets is farther to the left of the number line and as such represents a greater depth value Than - 68 feets
Therefore, when expressing depth or elevation distances, the values should be iewwd in absolute terms. Then |75| > |68|. While bearing in mind that depth is downward and thus negative

Answers
Answer: This means that the population increased a 20% between the year 2000 and the year 2010.
Step-by-step explanation:
In this case, we have that 25,000 is the 100%.
Now we want to know which percentage represents 30,000
Let's suppose that the percentage is X.
Then we can have a system of equations:
30,000 = X
25,000 = 100%
To find the value of X, we can take the quotient of these two equations:
30,000/25,000 = X/100%
(30,00/25,000)*100% = X = 120%
Then in the 2000 we had a 100%, and in the 2010 there was a 120%.
The difference is:
120% - 100% = 20%
This means that the population increased a 20% between the year 2000 and the year 2010.

According to proportion if a tree casts a shadow of 40 feet it;s height is 20 feet.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
We know 1 yard is 3 feet.
Given, The shadow of the tree is 40 feet long. A yardstick placed next to the tree casts a 6-foot shadow and assuming the height of the tree to be x.
∴ x : 40 : : 3 : 6.

on the planet Jupiter, a ball this thrown upward at a velocity at 10m/s. It's height, h(t) meters after t seconds is given by the equation h(t)=-12.5(t-0.4)^2+4.
a) what is the maximum height the ball reaches?
b) what was the height of the ball when it was released from the throwers hand?
c) how many seconds after the ball was hit and did it land on the surface of Jupiter to the nearest second?
Answers
Answer:
a) The maximum height that the ball reaches is 4 meters.
b) The height of the ball when it is released from thrower's hand is 2 meters.
c) The ball will take approximately 0.966 seconds to hit the surface of Jupiter.
Step-by-step explanation:
a) Let [tex]h(t) = -12.5\cdot (t-0.4)^{2}+4[/tex], where [tex]t[/tex] and [tex]h(t)[/tex] are the time and height, measured in seconds and meters. Since this equation is in vertex form, the maximum height corresponds to the value associated with the dependent variable (height). That is:
[tex]h(t) -4 = -12.5\cdot (t-0.4)^{2}[/tex]
Hence, the maximum height that the ball reaches is 4 meters.
b) The height of the ball when the ball is released from thrower's hand is the height of the ball at [tex]t = 0\,s[/tex]. Then, we evaluate the function:
[tex]h(0) = -12.5\cdot (0-0.4)^{2}+4[/tex]
[tex]h(0) = 2\,m[/tex]
The height of the ball when it is released from thrower's hand is 2 meters.
c) The instants when the ball hits the ground are those instants [tex]t[/tex] so that [tex]h(t) = 0[/tex]. Then:
[tex]-12.5\cdot (t-0.4)^{2}+4 = 0[/tex]
[tex]-12.5\cdot (t^{2}-0.8\cdot t +0.16)+4 = 0[/tex]
[tex]-12.5\cdot t^{2}+10\cdot t +2 = 0[/tex]
By the Quadratic Formula we obtain the following roots:
[tex]t_{1} \approx 0.966\,s[/tex], [tex]t_{2}\approx -0.166\,s[/tex]
Only the first root is physically reasonable, since time is a positive real variable.
The ball will take approximately 0.966 seconds to hit the surface of Jupiter.
