Use the graphs of F and G to evaluate the functions.
Someone please explain how you would solve this. This was all the info given with the problem.
The value of the functions are:
(a) ( f - g )( 1 ) = - 1
(b) ( f · g )( 4 ) = 0
Before performing operations on functions, we must first comprehend the various function rules and how to get the function value at a given x-value. By applying this concept, we can determine the function value.
From the graphs, we have the functions,
f(x) = 2( | x - 2 | )
g(x) = - x + 4
Now,
(a) ( f - g )( 1 )
( f - g )( 1 ) = f( 1 ) - g( 1 )
( f - g )( 1 ) = 2 ( | 1 - 2 | ) - ( - 1 + 4 )
( f - g )( 1 ) = 2 ( | - 1 | ) - ( 3)
( f - g )( 1 ) = 2 - 3
( f - g )( 1 ) = - 1
(b) ( f · g )( 4 )
( f · g )( 4 ) = f( 4 ) · g( 4 )
( f · g )( 4 ) = 2( | 4 - 2| ) · ( - 4 + 4 )
( f · g )( 4 ) = 0

Students in 3 art classes cut 728 inches of ribbon into 8-inch long pieces. Two of the classes together cut 656 inches of ribbon. How many 8-inch long pieces of ribbon did the other class cut?
The number of 8-inch long pieces of ribbon that the other class cut is 9.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
Given that Students in 3 art classes cut 728 inches of ribbon into 8-inch long pieces. Therefore, the number of ribbon that 3 classes together cut is,
Number of ribbon cut by 3 classes together = 728 inches / 8 inches = 91
Further, it is given that two of the classes together cut 656 inches of ribbon. Therefore, the number of ribbon that 2 classes together cut is 656.
Number of ribbon cut by 2 classes together = 656 inches / 8 inches = 82
Now, the number of 8-inch long pieces of ribbon that the other class cut can be written as,
Number of pieces cut by other class
= Number of ribbon cut by 3 classes together - Number of ribbon cut by 2 classes
= 91 - 82
= 9
Hence, the number of 8-inch long pieces of ribbon that the other class cut is 9.

Hi could someone help my sister is asking me this question but I never learned this
Answer:
12 cm
Step-by-step explanation:
Volume of total shape = Volume of big rectangle - Volume of small rectangle
Volume of big rectangle = L×B×H
Volume of big rectangle = 10 cm×3 cm×2 cm
Volume of big rectangle = 60 cm
Volume of small rectangle = l×b×h
l = 10 cm - 6 cm = 4cm
Volume of small rectangle = 4 cm×3 cm×4 cm
Volume of small rectangle = 48cm³
Volume of total shape = 60cm³ - 48cm³
Volume of total shape = 12cm³
6) Jessica’s cat is stuck in a tree. The fire department comes to help rescue the cat. Using a 25 foot ladder that is 10 feet away from the base of the tree, how high will the firefighter climb to reach the cat?
The firefighter needs to climb a height of 22.91 foot to reach the cat.
What is the Pythagorean Theorem ?
Pythagorean Theorem states that the square of the hypotenuse of a right triangle equals the sum of squares of the lengths of the other two sides.
It is given that the hypotenuse of the ladder is 25 foot and it's base is 10 feet away from base of tree.
Using the Pythagorean theorem which states that :
H² = P² + B²
where ;
H = Hypotenuse , P = Perpendicular and B = base
We can find out the height up to which the firefighter needs to climb to reach the cat. And it is given by :
25² - 10² = P²
625 - 100 = P²

There is probably diverse clinically and scientifically sound alternative subscale combinations for the predominant outcome degree.foremost findings: The statistical effectiveness of diverse subscale combinations is decided with the aid of the relative effect size of the intervention on every subscale as well as the correlation between the subscales. easy formulae may be installed to determine the relative statistical efficiency of each clinically appropriate subscale aggregate. Hypothetical situations imply that the variety of participants required in a scientific trial is probably twice as huge for a few subscale combinations as for others.Conclusions:

Step-by-step explanation:
solve for x32=10+ x/2
Answer:
x=44
Step-by-step explanation:
x32=10+x/2
Multiply the 2 from x over 2 to reverse the division equation.
2*x32=10+x/2*2
That results in 2 multiplying 32x and 2 multiplying the 2 in x over 2.
Because multiplication is the reverse of division, the 2's will cancel out and reduce x over to 2 to simply x.
2*32 is 64, include the x before the 64 just like the given equation exemplifies with the x before the 32.
The equation looks like the following once put together: x64=10+x
Subtract the x from the 10+x side of the equation underneath the x64.
x64=10+x
-x -x
Which equals x63=10.
To receive the answer to this question, you have to divide the 63 on both sides.
63 divided by 63x leaves you with just the x.
63 divided by 10 leaves you with 6.3 in decimal form.
Thus, x equals 6.3.
To check if it's right, insert 6.3 for both x's.
(6.3)*32=10+(6.3)/2
Solve.
201.6=10+3.15
201.6=13.15
Clearly, this doesn't work.
So, I'm assuming you actually meant: 32=10+x/2.
Hence, you would multiply 2 on both sides.
2*32=10+x/2*2
We've established that 32*2 is 64 and the 2's would cancel out.
64=10+x
Subtract the 10 on both sides.
54=x
To see if this one is correct, plug in 54 to the x.
32=10+(54)/2
Divide 54 by 2 which equals 27.
32=10+27
32=37
Nope, that doesn't work either.
Thus, instead of multiplying by 2, we would first need to subtract the 10.
32=10+x/2
-10 -10
32-10 is 22 and it would leave the other side with just x over 2.
22=x/2
Now, we would have to multiply the 2 on both sides.
22*2=44 and x/2*2 gives us x.
So, 44=x.
Let's check.
32=10+(44)/2
32=10+22
32=32
Finally, we have our match.
In conclusion, x=44.
Hope this helps.

The person is blind. They did what they were supposed to except the fact that they didn't multiply the 8 by the -1.
Answer: The error is in step 3
Explanation:
In step 2, they multiplied both sides by 8 to clear out the fractions. In step 3, they forgot to distribute the 8 to each term inside the parenthesis.
This is what the steps should look like
[tex]\frac{3\text{x}}{8}-1=\frac{5}{8}\\\\\\8\left(\frac{3\text{x}}{8}-1\right)=8\left(\frac{5}{8}\right)\\\\\\3\text{x}-8 = 5\\\\\\3\text{x} = 13\\\\\\\text{x} = \frac{13}{3}\\\\\\[/tex]
In step 4, we added 8 to both sides. Afterward, divide both sides by 3 to fully isolate x.

a house at the bottom of a hill is fed by a full tank of water 5.pm deep and connected to the house by a pipe that is 110m long at an angle of 58 degrees from the horizontal
The water gauge pressure at the house will be 9.63×10⁵ N/m².
Firstly we will be calculating the total height which will comprise of height from tank to house and elevated height. The formula for total height will be -
Total height = 5 + 110 sin 58°
Keep the value of sin 58° in formula and performing multiplication followed by addition
Total height = 5 + 110×0.848
Total height = 5 + 93.28
Total height = 98.28 meters
Now, calculating the water gauge pressure at house. The formula to be used is -
P = ρ×g×h, where P is pressure, ρ is density of water, g refers to acceleration due to gravity and h represents total height. We are aware that density of water is 1000 kg/m³ and accelerate due to gravity is 9.8 m/s².
Keep the values in formula to find the gauge pressure.
P = 1000 × 9.8 × 98.28
Performing multiplication
P = 963,144 N/m² or 9.63×10⁵ N/m²
Hence, the water gauge pressure at the house will be 9.63×10⁵ N/m².
The complete question is -

Find the approximate side length of a square game board with an area of 105 in2.
Answer:
Rounded to the nearest inch: 10
Rounded to the nearest tenth: 10.2
Rounded to the nearest hundredth: 10.25
Step-by-step explanation:
To find the area of a square, we multiply the side length by itself, or in other words, SQUARE the side length!
[tex]A=s^2[/tex]
We are given the area, so plugging that into our equation looks like this:
[tex]105=s^2[/tex]
To eliminate the exponent, take the square root of both sides of the equation!
[tex]\sqrt{105}=s[/tex]
From here, there are a few paths to take, depending on what your teacher is looking for. I will evaluate the approximate of the square root by finding the nearest perfect squares.
The nearest perfect square less than √105 is √100, and the nearest perfect square greater than √105 is √121.
105 is closer to 100 than to 121, so √105 is closer to √100.
√100 is equal to 10, so the √105 is approximately 10 inches!
Using a calculator to check:
