Let g(x) = 9x + 24
find g(3)
Let g(x)=9x+24, find g(3).
Answer:
51
Step-by-step explanation:
Plug in 3 as x into the function:
g(x) = 9x + 24
g(3) = 9(3) + 24
g(3) = 27 + 24
g(3) = 51
g(x) = 9x + 24
g(3) = 9(3) + 24
g(3) = 27 + 24 = 51
Answer:g(3) = 51

Consider w=sqrrt2/2(cos(225°) + isin(225°)) and z = 1(cos(60°) + isin(60°)). What is w+ z expressed in rectangular form?
Answer:
Option (3)
Step-by-step explanation:
w = [tex]\frac{\sqrt{2}}{2}[\text{cos}(225) + i\text{sin}(225)][/tex]
Since, cos(225) = cos(180 + 45)
= -cos(45) [Since, cos(180 + θ) = -cosθ]
= -[tex]\frac{\sqrt{2}}{2}[/tex]
sin(225) = sin(180 + 45)
= -sin(45)
= -[tex]\frac{\sqrt{2}}{2}[/tex]
Therefore, w = [tex]\frac{\sqrt{2}}{2}[-\frac{\sqrt{2}}{2}+i(-\frac{\sqrt{2}}{2})][/tex]
= [tex]-\frac{2}{4}(1+i)[/tex]
= [tex]-\frac{1}{2}(1+i)[/tex]
z = 1[cos(60) + i(sin(60)]
= [tex][\frac{1}{2}+i(\frac{\sqrt{3}}{2})[/tex]
= [tex]\frac{1}{2}(1+i\sqrt{3})[/tex]
Now (w + z) = [tex]-\frac{1}{2}(1+i)+\frac{1}{2}(1+i\sqrt{3})[/tex]
= [tex]-\frac{1}{2}-\frac{i}{2}+\frac{1}{2}+i\frac{\sqrt{3}}{2}[/tex]
= [tex]\frac{(i\sqrt{3}-i)}{2}[/tex]
= [tex]\frac{(\sqrt{3}-1)i}{2}[/tex]
Therefore, Option (3) will be the correct option.

Which pair of functions are inverses of each other?
A. f( x ) = 6/x − 5 and g ( x ) = x + 5 /6
B. f(x) = 8x – 3 and g ( x ) = x + 3/8
C. f ( x ) = sqr 3 7x and g ( x ) = ( x /7 )3
D. f ( x ) = x /9 + 1 2 g(x) = 9x – 12
The inverse of the function is f(x) = 8x – 3 and g ( x ) = x + 3/8. The correct option is B.
What is an inverse function?A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
The inverse function of a function f in mathematics is a function that reverses the operation of f. If and only if f is bijective, then the inverse of f exists, and if it exists.
The inverse of the function is given by,
f(x) = 8x – 3 and g ( x ) = x + 3/8
The inverse of the function is calculated by dividing the function by the coefficient of x and reversing the sign of the function.
f(x) = 8x – 3
Divide the function by 8.
f(x) = ( 8x - 3 ) / 8
Reverse the sign of the function.
f(x) = ( 8x + 3 ) / 8
Simplify the function.
f(x) = ( x + 3 / 8 ).
Therefore, the inverse of the function is f(x) = 8x – 3 and g ( x ) = x + 3/8. The correct option is B.

Población de alces. Se introducen cíen alces en una reserva zoológica, cada uno de un año de edad. El número N(t) de animales vivos después de t años se predice mediante N(t) = 100(0.9) t Estima el número de animales vivos después de:
Answer:
El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.
Step-by-step explanation:
Sabes que el número N(t) de animales vivos después de t años se predice mediante N(t) = 100*[tex]0.9^{t}[/tex]
Para estimar el número de animales vivos después de, por ejemplo, 1 año debes simplemente reemplazar el tiempo t por el tiempo correspondiente, en este caso 1 año:
N(1) = 100*[tex]0.9^{1}[/tex]
Resolviendo:
N(1) = 100*[tex]0.9^{1}[/tex]= 100*0.9= 90
De manera similar, podes estimar el número de animales vivos después de 5 y 10 años. Esto es, reemplazas t por 5 años:
N(5) = 100*[tex]0.9^{5}[/tex]= 100*0.59049= 59.049≅ 60
y t por 10 años:
N(10) = 100*[tex]0.9^{10}[/tex]= 100*0.3487= 34.86 ≅ 35
El número de animales vivos después de 1, 5 y 10 años es 90, 60 y 35 respectivamente.

PLEASE HELP As a part-time job, ethan makes deliveries for a caterer. In addition to his weekly salary, he is also paid 16$ Per delivery. Last week, he made 5 deliveries and his total salary was $215. Write a linear equation to find Ethan's total weekly salary S if he makes d deliveries.
you know he made 5 deliveries for $16 each. 5*16=80. So to find his salary you have 215-80=$135.
So he makes $135 no matter what plus $16 times the number of deliveries.
so, S=16d+135

Allison is making treat bags for Valentine's Day. She uses 7 sheets of stickers
and 3 bags of candy for every 8 friends. If Allison is making 14 treat bags, how
many sheets of stickers will she use? How many bags of candy?
The number of sheets of stickers is 12.25, and the number of bags of candy is 5.25 she will use.
What is the ratio?It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign: between the numbers.
Allison uses 7 sheets of stickers and 3 bags of candy for every 8 friends.
It means the ratio of the sticker to candy bags:
7:3 for 8 friends
[tex]\frac{7}{8} :\frac{3}{8}[/tex] for 1 friend or
0.875:0.375
If she makes 14 treat bags then:
The number of sheets of stickers she will use = 0.875×14 ⇒ 12.25
The number of bags of candy she will use = 0.375×14 ⇒ 5.25
Thus, the number of sheets of stickers is 12.25, and the number of bags of candy is 5.25 she will use.

∆GHI is an isosceles triangle with a vertex angle H
If the m∠H=80°, then find the m∠I.
Given :
∆GHI is an isosceles triangle with a vertex angle H.
m∠H=80°
To Find :
The m∠I.
Solution :
Since, H is the vertex angle.
So, m∠I = m∠G = x
We know, by angle sum property of triangle :
m∠I + m∠G + m∠H = 180°
2x + 80° = 180°
x = 50°
Therefore, m∠I = 50° .
Answer:
the answer is actually 75 degrees

Find the 18th term of the arithmetic sequence whose common difference is d = 2 and whose first term is a, = 3.
Answer:
The 18th term of the arithmetic sequence will be:
[tex]a_{18}=37[/tex]
Step-by-step explanation:
We know that the arithmetic sequence with a common difference 'd' and the first term 'a₁' is defined as
[tex]a_n=a_1+\left(n-1\right)d[/tex]
Given the values
d = 2
a₁ = 3
As we have to determine the 18th term of the arithmetic sequence.
so putting n = 18 in the nth term to determine the 18th term.
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_{18}=3+\left(18-1\right)2[/tex]
[tex]=3+17\cdot \:2[/tex]
[tex]=3+34[/tex]
[tex]=37[/tex]
Therefore, the 18th term of the arithmetic sequence will be:
[tex]a_{18}=37[/tex]
If the equation y=3x−1 y = 3 x − 1 were graphed on the xy-coordinate plane, which of the following would not be a point on that graph?
Answer:
See Explanation
Step-by-step explanation:
This question requires options.
Since, there are none, I'll answer on a general term.
For a coordinate point to be on the graph, the x and y value when substituted in the given equation must make the equation true.
Take for instance
(x,y) = (1,2)
This implies that
x = 1
y = 2
Substitute values of x and y in
y = 3x - 1
We have:
2 = 3 * 1 - 1
2 = 3 - 1
2 = 2
Notice that both sides of the equation are equal.
Hence
(1,2) lies on the xy coordinate plane.
However,
Take for instance (x,y) = (2,4)
This means
x = 2 and y = 4
Substitute values of x and y in
y = 3x - 1
4 = 3 * 2 - 1
4 = 6 - 1
4 ≠ 5
The above does not represent an equation because 4 is not equal to 5.
Hence, (2,4) does not lie on the coordinate plane
So, to answer your question, you need to substitute values of x and y in the given equation.
Which ever of the options that does not show equality answers your question.

If a board 8 ¾ ft. long is cut into 7 equal parts, how long is each part?
Answer:
26 5/32 in. or 2 ft
Step-by-step explanation:
Since we are taking into account 1/8in for each saw cut the total length of the 4 pieces of wood will be 3/8in less than the single long piece (3 cuts * 1/8).
Let's first convert the piece of wood to inches:
8 3/4ft = 8.75ft
8.75 ft *(12in./1ft) => 8.75 *12= 105 inches
Now we can subtract the 3/8in that will be lost from making 3 cuts:
105in. - 3/8in. = 104 5/8in.
So the total length of the 4 pieces of wood will be 104 5/8in.
Therefore, each piece will be (104 5/8in)/4 in length.
First let's convert 104 5/8in. to an improper fraction to make it easier to work with:
104 5/8in. = (104*8 + 5)/8in.
=837/8in.
Now we can divide this by 4 to get the length of each piece of wood:
(837/8in.)/4 is the same as (837/8in.)*(1/4)
Multiply numerators together, and multiply the denominators together:
(837/8in.)*(1/4) = 837/32in.
Convert back to a mixed number if needed:
837/32in.= 26 5/32in. or 2ft, 2 5/32in.
