Here, for h(f(2)), the first one to put in is the one in f, which is 2.
Since f(x) = 3*2^x, and since x here is equal to 2, (because h(f(2)), we can just put in the 2 in place of the x.
3 * 2 ^ 2
And then you get:
3 * 4
Or 12.
So now you have
h(12)
Now do the same thing.
2 * 12 - 7
24 - 7

What can you infer about elements that are in the same group?
a. they will have the same atomic mass
b. they will display similar chemical and physical properties
c. they will contain the same number of protons
d. they will emit x rays of similar frequency
Answers
Elements of the same group in the Periodic Table will have similar chemical and physical properties.
Answer:
b.They will display similar chemical and physical properties.
Step-by-step explanation:
We have to find about the elements that are in the same group.
In modern periodic table
Elements are arranged in group according to similar properties.
The elements which have same properties are placed in the same group and mass of different elements are different in the group.
The outer electronic configuration of every element in the same group are same.
Therefore, the physical and chemical properties of the elements are same in the group.
Hence, option B is true.
Answer:b.They will display similar chemical and physical properties.
You are going to order some of your favorite cookies. If you order two boxes it will cost you $14. If you place an order for eight boxes it will cost you $26. Write an equation that represents the cost of ordering your favorite cookies.
Step 1: Decide what information represents your two points.
Hint: The points are in the format (number of boxes of cookies, cost) as these are your two variables.
Point 1: Point 2:
Step 2: Use your two points to write an equation.
Answers
so im just gonna try and guess what the equation might be ^-^
14 devided by 2=?
26 devided by 8=?
then multiply the two answers to get the final answer.
(note im not trying to take points im just trying to help out a friend so im sorry if its wrong chika)
How do we plot the points?
We should obviously start out with a graph. We only need Quadrant I. We will let our x-axis (the horizontal axis) contain the number of boxes of cookies, and our y-axis (the vertical one) contain our prices.
We put our number of boxes on the x-axis because it is the independent variable, while the price per box goes on the y-axis because it is the dependent variable.
At this "point," we should be able to plot our numbers at the proper points. We can simply line up our "dot" (point) with the information given, so that Point 1 is (2 , 14) and Point 2 is (8 , 26). We know that information from the prompt.
Now, we simply need to draw a line that connects these 2 points.
Once we have done that, we need to remember the equation for a line. This is "y=mx+b" where "m" is our slope and "b" is our y-intercept. Our slope is going to be in a fraction with the format [tex] \frac{rise}{run}[/tex], or the change in the y-value over the change in the x-value.
When we work this out, we will find that the equation for this is y=2x+10.
Below, I have attached an image of the graph that we should make while doing this. Note that this graph "goes by 2s." The red point represents 2 boxes for 14 dollars. The blue point represents 8 boxes for 26 dollars. The green line represents the relationship between them.

if a 40-foot tree casts a 12-foot shadow,find the length of a shadow cast by a 23-foot tree
Answers
shadow:length=12:40=3:10
if length is 23 then
3:10=?:23
3/10=?/23
multiply both sides by 23
69/10=?
6.9=?
6.9ft is the shadow length
The length of the shadow cast by the 23 feet tree is 6.9 feet
What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
Let the height of the tree A = 40 feet
The height of the shadow of the tree A = 12 feet
Now ,
The height of the tree B = 23 feet
Let the height of the shadow of the tree B = x
So , the proportion equation is
height of the shadow of the tree A / height of the tree A = height of the shadow of the tree B / height of the tree B
And the proportion will be ,
12 / 40 = x / 23
Multiply by 23 on both sides , we get
x = ( 12 × 23 ) / 40
x = ( 3 × 23 ) / 10
x = 69 / 10
x = 6.9 feet
Therefore , the value of x is 6.9 feet
Hence , The length of the shadow cast by the 23 feet tree is 6.9 feet

the current value of a baseball card is 80 times its original value the baseball card is worth $36 write and solve an equation to find the original value of the baseball card
Answers
To find the original value of a baseball card that is now worth 80 times its original value, you divide the current value of $36 by 80, resulting in an original value of $0.45.
Explanation:The student wants to find the original value of a baseball card that is currently worth 80 times its original value and has a present worth of $36. We set up the equation: original value multiplied by 80 equals current value (80 × original value = $36). To find the original value, we divide the current value by 80.
Write the equation: 80 × original value = $36.Divide both sides of the equation by 80 to isolate the original value. So, original value = $36 ÷ 80.Calculate the result: original value = $0.45.The original value of the baseball card was $0.45.

A) circle
B) line segment
C) parallel lines
D) perpendicular lines
Answers
Answer:
1. Angle
2. Line Segment
Step-by-step explanation:
Two lines or rays diverging from a common point defines an 'angle', which is a figure forming from two rays starting from the same end-point.
Now, a figure bounded by two distinct end points which contain every point on the line between its end points defines a 'line segment'.
Hence, the answer are: Angle and Line Segment respectively.

What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The length of pen for his horse = 40 yards
The width of pen for his horse = 50 yards
And, The fencing comes in 5 foot pieces,
Now,
The perimeter of the pen for his horse = 2 (50 + 40)
= 2 x 90
= 180 yards
Since, The fencing comes in 5 foot pieces,
Hence, Number of pieces to buy by Mr. rancher = 180 / 5
= 36
Thus, There are 36 pieces need to buy by Mr. rancher.

Alan drove 756 miles in 12 hours. at the same rate, how many miles would he drive in 8 hours?
Answers
756 mi/12 hrs= 63 mph
Multiply the speed by time to get distance.
63 mph* 8 hrs= 504 mi
Final answer: 504 mi
Alan would drive 504 miles in 8 hours.
Explanation:To find out how many miles Alan would drive in 8 hours, we can set up a proportion using the information given. Since Alan drove 756 miles in 12 hours, we can write the proportion as:
12 hours / 756 miles = 8 hours / x miles.
To solve for x, we can cross-multiply and then divide:
12 * x = 8 * 756
x = (8 * 756) / 12
x = 504
Therefore, Alan would drive 504 miles in 8 hours.

WE need to select an ordered pair that is solution to our inequality
Lets check with each option
(2,0) , plug in 2 for x and 0 for y
[tex]4x+y>-6[/tex]
[tex]4(2)+0>-6[/tex]
[tex]8>-6[/tex] True
(−3, 6), plug in -3 for x and 6 for y

Final answer:
The ordered pairs that are solutions to the inequality 4x+y>-6 are (2, 0), (4, -20), and (-1, -1) as they satisfy the condition when substituted into the inequality.
Explanation:
To determine which ordered pairs are solutions to the inequality 4x+y>-6, we need to plug the x and y values from each ordered pair into the inequality.
For the pair (2, 0), we substitute x = 2 and y = 0 into the inequality: 4(2) + 0 > -6, which simplifies to 8 > -6. This is true, so (2, 0) is a solution.For the pair (-3, 6), we substitute x = -3 and y = 6: 4(-3) + 6 > -6, which simplifies to -12 + 6 > -6. This gives -6 > -6, which is not true, so (-3, 6) is not a solution.For the pair (4, -20), we substitute x = 4 and y = -20: 4(4) - 20 > -6, which simplifies to 16 - 20 > -6. This gives -4 > -6, which is true, so (4, -20) is a solution.For the pair (0, -9), we substitute x = 0 and y = -9: 4(0) - 9 > -6, which simplifies to -9 > -6. This is not true, so (0, -9) is not a solution.For the pair (-1, -1), we substitute x = -1 and y = -1: 4(-1) - 1 > -6, which simplifies to -4 - 1 > -6. This gives -5 > -6, which is true, so (-1, -1) is a solution.The correct solutions to the inequality are the ordered pairs (2, 0), (4, -20), and (-1, -1).
