Let f(x)=5x+2 and g(x)=5x^2+4x. After simplifying, (f⋅g)(x)=______
Answer: [tex]f(g(x))=25x^{2}+20x+2\\[/tex]
Step-by-step explanation:
(f·g)(x) also means f(g(x)).
So basically what we do is take the function g(x) and plug it into f(x) where ever there is the variable x.
[tex]f(g(x))=5(5x^{2}+4x)+2[/tex]
Now distribute the 5.
[tex]f(g(x))=25x^{2}+20x+2[/tex]
This is as simplified the equation gets as it is not factor-able.
A coordinate plane with 2 lines drawn. The first line is labeled f(x) and passes through the points (0, negative 2) and (1, 1). The second line is labeled g(x) and passes through the points (negative 4, 0) and (0, 2). The lines intersect at about (2.5, 3.2) How does the slope of g(x) compare to the slope of f(x)? The slope of g(x) is the opposite of the slope of f(x). The slope of g(x) is less than the slope of f(x). The slope of g(x) is greater than the slope of f(x). The slope of g(x) is equal to the slope of f(x).
Answer:
B. The slope of g(x) is less than the slope of f(x)
Step-by-step explanation:
The slope of f(x) is 2/1 or just 2 and the slope of g(x) is 1/2, less than f(x).

B.

How many degrees will the Australia section be in a circle graph of this data?
52
20°
29°
104
Answer:
I believe it is 104 degrees.
Step by Step: First, You add all the medals for all the countries, giving you 69. Then, you make Australia's medals a fraction of 69, so 20/69. After this, since a circle has 360 degrees, you make x/360 and cross multiply. This takes you to 69x=7200. Now divide 7200 by 69, which gets you 104.347, or 104 degrees.
Answer:
104 deg
Step-by-step explanation:
Total number of medals: 31 + 20 + 6 +6 + 6 = 69
Number of Australian medals: 20
Fraction of total medals won by Australia: 20/69
A circle has a total of 360 deg.
Since Australia has 20/69 of the medals, it will have 20/69 of 360 degrees in the circle graph.
20/69 * 360 = 104.3
Answer: 104 deg

Find the area of the following shape, given its curves are made from parts of circles with diameters indicated on the diagram. Give your answers in terms of π .
Answer: Area = 26π + 20 cm²
Step-by-step explanation:
There are 2 large semicircles = 1 large circle
There are 2 small semicircles = 1 small circle
There is 1 rectangle.
Find the Area of each shape above and then find their sum.
1) Large Circle: A = πr², d = 10 --> r = 10/2 = 5
A = π(5)²
= 25π
2) Small Circle: A = πr² , d = 2 --> r = 2/2 = 1
A = π(1)²
= π
3) Rectangle: A = length × width, L = 10 w = 2
A = 10 × 2
= 20
Total = Large + Small + Rectangle
= 25π + π + 20
= 26π + 20

What is the question?
Answer:
(23, 4)
Step-by-step explanation:
If we use substitution, we need to rewrite the 2nd equation so we can substitute it into the first.
Step 1: Rewrite 2nd equation
x = 5y + 3
Step 2: Substitution
2(5y + 3) - 5y = 26
Step 3: Distribute
10y + 6 - 5y = 26
Step 4: Combine like terms
5y + 6 = 26
Step 5: Isolate y
5y = 20
y = 4
Step 6: Find x
x - 5(4) = 3
x - 20 = 3
x = 23
And we have our final answer!
Answer:
(23,4)
Step-by-step explanation:
x-5y=3
+5y=+5y
x=3+5y
-- Plug that into X for the other Equation
2(3+5y)-5y=26
Solve for y
2(3+5y)-5y=26
Distribute the 2
6+10y-5y=26
Simplify
6+5y=26
-6 =-6
5y=20
(divide by 5)
y=4

Given that y varies inversely with x, if x =7 and y = 4, what is y when x = 2?
Answer:
y = 14
Step-by-step explanation:
y ∝ [tex]\frac{1}{x}[/tex]
=> y = [tex]\frac{k}{x}[/tex] -------------(1)
Where k is the constant of proportionality
Now,
x = 7, y = 4
Putting in (1)
4 = [tex]\frac{k}{7}[/tex]
So,
=> k = 28
Now y = ? when x = 2
Putting x and k in (i)
y = [tex]\frac{28}{2}[/tex]
y = 14
Answer:
[tex]y=14[/tex]
Step-by-step explanation:
[tex]y \propto 1/x[/tex]
[tex]y=k/x[/tex]
[tex]4=k/7[/tex]
[tex]4 \times 7 = k[/tex]
[tex]28=k[/tex]
[tex]y=28/x[/tex]
[tex]y=28/(2)[/tex]

The Fibonacci sequence 1, 1, 2, 3, 5, 8, 13, 21, … starts with two 1s, and each term afterward is the sum of its two predecessors. Which one of the ten digits is the last to appear in the ones position of a number in the Fibonacci sequence?
Answer:
6
Step-by-step explanation:
Note that any digits other than the units digit will not affect the answer. So to make computation quicker, we can just look at the Fibonacci sequence in $:
$1,1,2,3,5,8,3,1,4,5,9,4,3,7,0,7,7,4,1,5,6,....$
The last digit to appear in the units position of a number in the Fibonacci sequence is $6.

Answer:
V = 1330.5 cm³
Step-by-step explanation:
Diameter = 11 cm
Radius = 5.5 cm
Height = 14 cm
Now, The volume:
Volume of Cylinder = [tex]\pi r^2h[/tex]
V = [tex](3.14)(5.5)^2(14)[/tex]
V = [tex](3.14)(30.25)(14)[/tex]
V = 1330.5 cm³
Answer:
1330.5 cm³
Step-by-step explanation:
The volume of a cylinder is equal to πr²h.
Where r is the radius and h is the height.
The diameter is 11 cm, so the radius will be 5.5 cm.
π(5.5)²(14)
π(30.25)(14)
423.5π = 1330.464489
Rounded to 1 decimal place will be 1330.5 cm³.
A square and rectangle have the same area. The length of the rectangle is 5cm more than twice the length of the side of the square. The width of the rectangle is 6cm less than the side of the square. Find the length of the side of the square.
Answer:
10cm
Step-by-step explanation:
First let's define variables a and x:
a = area of rectangle and square
x = side of square
Now let's create an equation to calculate a using the square and an equation to calculate a using the rectangle:
Using square: [tex]x^{2} =a[/tex]
Using rectangle: [tex](5+2x)(x-6)=a[/tex]
Now we want to solve for x so let's combine the equations since they are both equivalent to a
[tex](5+2x)(x-6)=x^{2}[/tex]
Simplify
[tex]x^{2}-7x-30 = 0[/tex]
Solving this we get 10 and -3
Since it is impossible for a square to have a negative side value we can conclude that the value is 10cm
This can then be checked by plugging in 10 as x in our equations and seeing if we get the same a value:
Using square: [tex]10^{2} = 100[/tex]
Using rectangle: [tex](5+2(10))(10-6) = (25)(4) = 100[/tex]

Answer:
234.85
Step-by-step explanation:
This was easy!!!
(The gardener comes 4 times a month... so divide 85.40 by 4 and you will get 21.35. Each time he comes, he gets 21.35 and by the end of the month, he has 85.40. It says he already came 11 times. So 4 + 4 = 8 + another 4 that equals 12. He came only two months and a few weeks. This means multiply 85.40 by 2 so you would get 170.8. It said he came 11 times so substract 11 from 8 and you would get 3. So multiply 21.35 by 3 and get a total of 64.05. Add 170.8 and 64.05 to get 234.85!!! The answer is 234.85 or C!!!!
Answer: C. $234.85

Step-by-step explanation:
Elimination Method:
R - 9S = 2
3R - 3S = -10
I'll solve for X first by eliminating S.
R - 9S = 2
-3(3R - 3S = -10)
R - 9S = 2
-9R + 9S = 30
(Add the equations)
-9R = 32
(Divide both sides by -9)
-9R/-5 = 32/-5
R = -4
Substitute the R value into either equation:
R - 9S = 2
(-4) - 9S = 2 (Add 4 to both sides of the equation)
+4 +4
-9S = 6 (Divide both sides of the equation by -9)
-9S/-9 = 6/-9
S = -6/9

a gram is equevalint to 0.0353 ounces one ounce is how may grams round to the nearest tenth
Answer:
28.3
Step-by-step explanation:
Since 1 gram = 353/10000 ounces, then to make the right side 1, you must multiply by the reciprocal, or 10000/353 to make it 1. Then you get 10000/353 grams = 1 ounce. Now, we divide and round to the nearest tenth. This is 28.3 grams.
