A structural steel fabricator cuts 25 pieces each 16.2 centimeters long from a 6.35-meter length
of channel iron. Allowing 4 millimeters waste for each piece, find the length in meters of
channel iron left after all 25 pieces have been cut.
Answer: 2.2 meters
Step-by-step explanation:
The data is:
The initial piece is 6.35 meters long.
We cut 25 pieces of 16.2cm each, so in pieces only we have:
25*16.2cm = 405cm
1m = 100cm
Then: 405cm = (405/100) m = 4.05m
And each time that we cut a piece, we have 4mm of waste.
Then we have 25 times the 4mm of waste, this means that the total waste is:
4mm*25 = 100mm
and 1000mm = 1m
100mm = (100/1000) m = 0.1m
So the total amount that was cut is:
4.05m + 0.1m = 4.15m
The length in the channel iron will be: 6.35m - 4.15m = 2.2 meters

Find the following:
a. g(h(x))=_______
b. h(g(x))=_______
c. h(h(x))=_______
Complete Question
The complete question is shown on the first uploaded image
Answer:
a
[tex]g(h(x)) = \sqrt[4]{x^2 + x +5} + 3[/tex]
b
[tex]h(g(x)) = \sqrt{x} + 7\sqrt[4]{x} + 17[/tex]
c
[tex]h(h(x)) = [x^2 + x + 5 ]^2 + x^2 + x + 10[/tex]
Step-by-step explanation:
From the question we are told that
[tex]h(x) = x^2 + x + 5[/tex]
and
[tex]g(x) = \sqrt[4]{x} + 3[/tex]
Considering first question
Now we are told g(h(x))
i.e
[tex]g(h(x)) = [x^2 + x + 5 ]^{\frac{1}{4} } + 3[/tex]
=> [tex]g(h(x)) = \sqrt[4]{x^2 + x +5} + 3[/tex]
Considering second question
Now we are told h(g(x))
i.e
[tex]h(g(x)) = [x^{\frac{1}{4} } + 3]^2 + x^{\frac{1}{4} } + 3 + 5[/tex]
=> [tex]h(g(x)) = x^{\frac{1}{2} } + 6x^{\frac{1}{4} } + 9+ x^{\frac{1}{4}} + 8[/tex]
=> [tex]h(g(x)) = x^{\frac{1}{2}} + 7x^{\frac{1}{4}} + 17[/tex]
=> [tex]h(g(x)) = \sqrt{x} + 7\sqrt[4]{x} + 17[/tex]
Considering third question
[tex]h(h(x))= [x^2 + x + 5]^2 + [x^2 + x + 5 ] + 5[/tex]
=> [tex]h(h(x)) = [x^2 + x + 5 ]^2 + x^2 + x + 10[/tex]

After a windstorm, a leaning pole makes a 75° angle with the road surface. The pole casts a 15-foot shadow when the sun is at a 45° angle of elevation. About how long is the pole?
a) 11.0 ft.
b) 12.2 ft.
c) 16.7 ft.
d) 20.5 ft.
9514 1404 393
Answer:
b) 12.2 ft
Step-by-step explanation:
Based on the attached and the answer choices, it looks like we're to assume the pole is leaning away from the sun. Of course, we must assume the angle the pole makes with the ground and the angle of elevation are in the same plane.
The problem can be solved using the law of sines. In the attached, we have ...
AD/sin(O) = OA/sin(D)
The angle at D is 180° -45° -75° = 60°, so this can be written as ...
AD = sin(45°)(15 ft)/sin(60°)
AD ≈ 12.247 ft
The pole is about 12.2 feet long.
Determine the number of triangles ABC possible with the given parts.
b = 24, c = 29, B = 43°
9514 1404 393
Answer:
2
Step-by-step explanation:
In general, if the given angle is opposite the shorter of the two given sides, there will be 0 or 2 possible triangles. The attachments show the two possibilities.
__
There will be zero possible triangles if the ratio of sides is less than the sine of the angle. Here, 24/29 ≈ 0.8276, sin(43°) ≈ 0.6820. The ratio of sides is greater, so there are two possible triangles.
If the given angle is opposite the longer of the two given sides, there is one possible triangle. The same is true if the given angle is between the two given sides.

2(a + 6) – 3(a – 5) = 18
Answer: A= 9
Step-by-step explanation:
2(a+6)-3(a-5)=18
FIRST YOU WANT TO DISTRUBUTE THE PARENTHESIS
2a + 12 -3a + 15 =18
ADD AND SUBTRACT LIKE TERMS
-1a + 27 = 18
SUBTRACT 27 ON BOTH SIDES
-1a + 27 =18
- 27 -27
-1a= -9
DIVIDES -1 ON BOTH SIDES AND NEGATIVES CANCEL OUT SO IT WOULD BE
A= 9

(c) Use composition to express s as a function of t.
s(t) =
Answer:
a)[tex]s=\sqrt{1+d^2}[/tex]
b)d(t)=500t
c)[tex]s(t) =\sqrt{1+250000t^2}[/tex]
Step-by-step explanation:
d = Horizontal distance
s = the distance between the plane and the radar station
The horizontal distance (d), the one mile altitude, and s form a right triangle.
So, use Pythagoras theorem
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
[tex]s^2=1^2+d^2[/tex]
a) [tex]s=\sqrt{1+d^2}[/tex]
(b) Express d as a function of the time t (in hours) that the plane has flown.
[tex]distance = speed \times time[/tex]
d(t)=500t
(c) Use composition to express s as a function of t.
[tex]s(t) =\sqrt{1+d^2}[/tex]
using b
[tex]s(t) =\sqrt{1+(500t)^2}\\s(t) =\sqrt{1+250000t^2}[/tex]

What is the slope of the line for the situation below in decimal form?
Answer:
5/4
Step-by-step explanation:
The slope should be 5/4 because if you go to a point on the line where the boxes meet on your graph and connect it to another point, you can count. I like to use rise over run, meaning you count up or down until you get level with the point you're trying to reach, and the run is the left or right until you get to the point you need. I really hope this helped! It may seem confusing at first, but you got it!

An oblique prism has a volume of 144 cubic units. The area of its base is 24 square units.
What is the perpendicular height of the prism?
2 units
4 units
6 units
8 units
Answer:
6
Step-by-step explanation:
the volume of a prism is always the base times the height this can be written as V = bh
we know the volume is 144 and the base is 24
substitute this into your equation: 144 = 24h
divide both sides by 24 to find h
144 ÷ 24 = 6
so you get h = 6
Assuming an oblique prism has a volume of 144 cubic units. The perpendicular height of the prism is 6 units.
Perpendicular height of the prismUsing this formula
Volume of prism=Base area ×Height
Hence:
144=24×h
h=144/24
h=6 units
Therefore, assuming an oblique prism has a volume of 144 cubic units. The perpendicular height of the prism is 6 units.

What is the equation in slope-intercept form of the line that passes through the points(-4,2) and (12,6)?
A. y = 0.25 x + 3
B. y = 0.25 x - 4.5
C. y = 4x + 18
D. y = 4x - 42
PLEASE HELP
Answer:
A
Step-by-step explanation:
Slope intercept form is y = mx + b
First find the slope or m with this equation [tex]\frac{y2 - y1}{x2 - x1}[/tex] (plug in) [tex]\frac{6 - 2}{12 + 4}[/tex] = [tex]\frac{4}{16}[/tex]= [tex]\frac{1}{4}[/tex]
So your slope is [tex]\frac{1}{4}[/tex]
To find the y-intercept you use y= mx + b and plug in.
6 = 1/4(12) + b
6 = 3 + b (minus 3 on both sides)
3 = b
so 3 is the y-intercept
So the answer is A.

The Minnesota Multiphase Personality Inventory (MMPI) is one of the most frequently used personality tests in psychology. The current standardized version, the MMPI-2, is used by trained professionals to assist in identifying personality structure and psychopathology. A forensic psychologist is interested in whether she can identify potential serial killers by their NMPI profiles. She is particularly interested in the Overcontrolled-Hostility and Defensiveness scales of the MMPI. She interviews 12 people who have already been identified as serial killers. Their scores on the Overcontrolled-Hostility scale are recorded here: Which of the following is a Possible value for the range?
a. 54
b. 22
c. 66
d. 79
Their scores on the Defensiveness scale are given here: Which of the following is a possible value for the range?
a. 33
b. 70
c. 53
d. 62
Answer:
1) A. 54
2) D. 62
Step-by-step explanation:
Find the complete question in the attached diagram.
Range is the difference between the highest score and the lowest score.
Given the following scores on the Overcontrolled-Hostility scale.
69, 84, 56, 89, 47, 63, 86, 58, 74, 35, 71, 60
From the data:
Highest score = 89
Lowest score = 35
Range = Highest score - Lowest score
Range = 89-35
Range = 54
Hence the possible value of the range is 54
For the scores on the Defensiveness scale given as:
38, 70, 35, 42, 26, 87, 74, 61, 69, 46, 63, 25
Highest score = 87
Lowest score = 25
Range = Highest score - Lowest score
Range = 87-25
Range = 62
Hence the possible value of the range is 62

3.2
Step-by-step explanation:
5.9 - 2.7 = 3.2
**difference means subtract**
The difference is between 2.7 and 5.9 on a number line.
What is Number Line?In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.
The numbers on the number line increase as one moves from left to right and decrease on moving from right to left.
Any directed number's location can be determined using a number line. There are positive and negative axes in it.
We have to determine the difference between 2.7 and 5.9 on a number line.
⇒ 5.9 - 2.7
Apply the subtraction operation between 2.7 and 5.9, and we get
⇒ 3.2
Therefore, the difference is between 2.7 and 5.9 on a number line.
