Answer: (a) $6,600
(b) $28,600
Step-by-step explanation:
Interest (I) = Principal (P) x rate (r) x time (t)
I = 22,000(0.06)(5)
= 6,600
Accrued (A) = Principal (P) + Interest (I)
A = 22,000 + 6,600
= 28,600
-4/40c+12/30 factor each expression completely
Answer:
[tex]\frac{4}{10}(-\frac{1}{4} c+1)[/tex]
Step-by-step explanation:
To factor the expression [tex]\frac{-4}{40}c+\frac{12}{30}[/tex] we use the GCF or greatest common factor. The greatest common factor is the greatest number that will divide into the values. We start to find it by factoring each term's coefficient:
[tex]\frac{2*2}{2*2*2*5}[/tex]
[tex]\frac{2*2*3}{2*3*5}[/tex]
We notice both have 2*2 in the numerator and 2*5 in the denominator. This is our GCF.
[tex]\frac{2*2}{2*5}=\frac{4}{10}[/tex]
We now write the expression 4/10(____+_____). We find the inside of the parenthesis by dividing the coefficients by the GCF. This is also the remaining factors which are not part of the GCF.
[tex]\frac{1}{2*2}=\frac{1}{4}[/tex]
[tex]\frac{3}{3}=1[/tex]
So the answer is [tex]\frac{4}{10}(-\frac{1}{4} c+1)[/tex]

Answer:
x = - 3 and x = - 4
Step-by-step explanation:
(a)
The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be.
solve x + 3 = 0 ⇒ x = - 3
(b)
Equate f(x) to 5, that is
[tex]\frac{2x+3}{x+3}[/tex] = 5 ( cross- multiply )
5(x + 3) = 2x + 3 ( distribute left side )
5x + 15 = 2x + 3 ( subtract 2x from both sides )
3x + 15 = 3 ( subtract 15 from both sides )
3x = - 12 ( divide both sides by 3 )
x = - 4
Find a cubic function that has the roots 5 and 3-2i
Answer:
[tex]P(x)=x^3-11x^2+43x-65[/tex]
Step-by-step explanation:
If the complex number [tex]3-2i[/tex] is a root of a cubic function, then the complex number [tex]3+2i[/tex] is a root too. Thus, the cubic function has three known roots [tex]5,\ 3-2i,\ 3+2i[/tex] and can be written as
[tex]P(x)=(x-5)(x-(3-2i))(x-(3+2i)),\\ \\P(x)=(x-5)(x^2-x(3-2i+3+2i)+(3-2i)(3+2i)),\\ \\P(x)=(x-5)(x^2-6x+9-4i^2),\\ \\P(x)=(x-5)(x^2-6x+9+4),\\ \\P(x)=(x-5)(x^2-6x+13),\\ \\P(x)=x^3-11x^2+43x-65.[/tex]
The cost of belonging to a gym can be modeled by C(m)= 50m + 79.50, where C(m) is the total cost for m months of membership. State the meaning of the slope and y-intercept of this function with respect to the cost associated with the gym membership.
Answer:
The slope is 50, which is the cost per month of the gym membership, and 79.50 is the y intercept. It represents the initial cost to join the gym.
Step-by-step explanation:
C(m)= 50m + 79.50,
This is written in the form y= mx+b where m is the slope and b is the y intercept.
The slope is 50, which is the cost per month of the gym membership, and 79.50 is the y intercept. It represents the initial cost to join the gym.
The slope of the function represents the cost of each additional month of membership, while the y-intercept represents the initial cost of joining the gym.
Explanation:The slope of the function C(m) = 50m + 79.50 represents the cost of each additional month of gym membership. In this case, the slope is 50, meaning that for every additional month of membership, the cost increases by $50.
The y-intercept of the function, which is 79.50, represents the initial cost of joining the gym. This can be considered as the one-time fee or the cost for 0 months of membership.

Find an exact value. sine of seventeen pi divided by twelve.
Answer:
4.45058959259........
And it still goes
The exact value of sin(17π/12) is -(√2 + √6)/4.
To find the exact value of sin(17π/12), we need to express 17π/12 as a sum or difference of angles for which we know the sine values. Since 17π/12 is not a standard angle, we'll use the angle addition formula.
17π/12 = (3π/4) + (2π/3)
Now, we'll use the sine addition formula:
sin(A + B) = sin(A)cos(B) + cos(A)sin(B)
Here, A = 3π/4 and B = 2π/3:
sin(3π/4 + 2π/3) = sin(3π/4)cos(2π/3) + cos(3π/4)sin(2π/3)
Now, we need to find the sine and cosine values of 3π/4 and 2π/3:
sin(3π/4) = √2/2, cos(3π/4) = -√2/2
sin(2π/3) = √3/2, cos(2π/3) = -1/2
Plugging these values into the formula:
sin(17π/12) = (√2/2 * -1/2) + (-√2/2 * √3/2)
= -√2/4 - √6/4
= -(√2 + √6)/4
So, the exact value of sin(17π/12) is -(√2 + √6)/4.

The surface area of a cube is 18 3/8 m square. Find its volume.
Answer:
[tex]5\frac{23}{64}\approx 5.36 [/tex] cubic meters.
Step-by-step explanation:
We have been given that the surface area of a cube is [tex]18\frac{3}{8}[/tex] square meters and we are asked to find the volume of the cube.
Since we know that surface area of a cube with each edge equals a units is:
[tex]\text{Total surface area of cube}=6a^2[/tex]
Let us find length of each edge using surface area formula.
[tex]18\frac{3}{8}=6a^2[/tex]
Let us convert our given area into mixed fraction.
[tex]\frac{147}{8}=6a^2[/tex]
Upon dividing both sides of our equation by 6 we will get,
[tex]\frac{147}{8*6}=a^2[/tex]
[tex]\frac{147}{48}=a^2[/tex]
Upon taking square root of both sides we will get,
[tex]\frac{7\sqrt{3}}{4\sqrt{3}}=a[/tex]
[tex]\frac{7}{4}=a[/tex]
Now we will use volume of cube formula with each side length 'a'.
[tex]\text{Volume of cube}=a^3[/tex]
[tex]\text{Volume of cube}=(\frac{7}{4})^3[/tex]
[tex]\text{Volume of cube}=\frac{343}{64}[/tex]
[tex]\text{Volume of cube}=5\frac{23}{64}[/tex]
[tex]\text{Volume of cube}=5.359375\approx 5.36[/tex]
Therefore, the volume of cube will be [tex]5\frac{23}{64}[/tex] cubic meters.
in the figure L1 L2 and L3 is a traversal what is the value of q-p
Answer:
q=135 degrees
p=45 degrees
Step-by-step explanation:
For q:
q is 135 degrees because alternate exterior angles are congruent when L1 is parallel to L2 intersected by L3.
For p:
p is 45 degrees because L2 is a straight line so it has a measurement of 180 degrees. So to find p you do 180 degrees-q.
Which is 180-135=45 degrees

Answer:
8x-12=6x-2 x=5
Step-by-step explanation:
if f(x)=3x-2 and g(x)=f(x)+3, write the equation for g(x)
g(x) = f(x) + 3
Since you know f(x) = 3x - 2, you can plug in (3x - 2) for "f(x)" in the equation:
g(x) = f(x) + 3
g(x) = (3x - 2) + 3
g(x) = 3x - 2 + 3
g(x) = 3x + 1

A.) y = 2x + 2
B.) y = 2x + 6
C.) y = -2x + 6
D.) y = - 1/2x + 2
Parallel lines have the same slope.
If y = 2x + 4, then parallel line has equal y = 2x + b.
The line passes throught the point (3, 8). Put the coordinates of the point to the equation of a line:
8 = 2(3) + b
8 = 6 + b subtract 6 from both sides

-x+3y=2
X+y=-2
Answer:
(-2, 0)
Step-by-step explanation:
Use elimination: add the two systems. Because the left is equal to right, you are adding the same thing and it's legal.
-x+3y=2
+ (x+y=-2)
Add each term
-x+x + 3y+y = 2+ -2
4y=0
y=0
x+y=-2
x+0=-2
x=-2
Answer:
x=-2, y=0
Step-by-step explanation:
-x+3y=2
X+y=-2
We can add these two equations together to eliminate x
-x+3y=2
x+y=-2
--------------
4y = 0
Divide each side by 4
4y/4 = 0/4
y=0
Now we still need to find x
x+y = -2
Substitute x=0
0+y = -2
y= -2

What is the equation of the line passing through the points (2, –1) and (5, –10) in slope-intercept form?
A)
Y=3x-5
B)
Y=3x+5
C)
Y=3x-5
D)
Y=3+5
Answer:
y = -3x+5 This has a negative slope
Step-by-step explanation:
The first step is to find the slope. We can use the formula
slope = (y2-y1)/(x2-x1)
= (-10--1)/(5-2)
= (-10+1)/3
= -9/3
=-3
Next we will use the point slope form of the equation of a line
y-y1 = m(x-x1)
y--1 = -3(x-2)
y+1 = -3(x-2)
Distribute the -3
y+1 = -3x -3*(-2)
y+1 = -3x+6
Subtract 1 from each side
y+1-1 = -3x+6-1
y = -3x+5
This is in the slope intercept form of the equation.

One evening 1400 concert tickets were sold for the Fairmont Summer Jazz Festival. Tickets cost $20 for covered pavilion seats and $15 for lawn seats. Total receipts were $24,000. How many tickets of each type were sold?
To determine how many tickets of each type were sold, two equations were formulated and the system was solved using the elimination method, resulting in 600 covered pavilion seats and 800 lawn seats sold.
To solve this problem we need to set up a system of equations based on the information provided. Let's define two variables: x for the number of covered pavilion seats sold, and y for the number of lawn seats sold. We know that together, a total of 1400 tickets were sold and the total receipts from these sales were $24,000. We can set up the following equations:
1) x + y = 1400 (total number of tickets sold)
2) 20x + 15y = 24,000 (total revenue from ticket sales)
To solve the system of equations, you can use either substitution or elimination method. Let's use the elimination method by multiplying the first equation by -15 and adding it to the second equation to eliminate y.
-15x - 15y = -21,000
20x + 15y = 24,000
Add the two equations:
5x = 3,000
Divide both sides by 5:
x = 600
Now we can substitute x back into the first equation to solve for y:
600 + y = 1400
y = 800
Therefore, 600 covered pavilion seats and 800 lawn seats were sold.

Answer:
c 61 units but it should be under a square root
Step-by-step explanation:
CA=6
CB=5
5^2+6^2=AB^2
61=AB^2
The Option C is partially correct , the answer must be under a square root as [tex]\;\sqrt {61} {\text{ units}}[/tex].
Further explanation:
The pythagorean theorem is used in the right angle triangle and it states that the square of the hypotenuse is equal to the sum of the squares of the perpendicular and base.
It can be mathematically expressed as,
[tex]{h^2} = {p^2} + {b^2}[/tex]
Here, [tex]h[/tex] is the hypotenuse, [tex]p[/tex] is the perpendicular and [tex]b[/tex] is the base.
Step by step explanation:
Step 1:
It is observed from given figure that after joining the points [tex]A,B{\text{ and C}}[/tex] it is established as right angle triangle.
First determine the perpendicular and the base of the triangle.
It can be seen that there are 5 boxes between the point [tex]A{\text{ and }}C[/tex] and 6 boxes between the point [tex]{\text{B and C}}[/tex].
Therefore, the perpendicular of the triangle [tex]AC[/tex] is [tex]{\text{6 units}}[/tex] and the perpendicular of the triangle [tex]AB[/tex] is .
Step 2:
Now use the Pythagoras theorem to find the distance between [tex]B{\text{ and }}A[/tex].
The distance between [tex]B{\text{ and }}A[/tex] is the length of the hypotenuse of the triangle [tex]ABC[/tex].
The length of the hypotenuse [tex]AB[/tex] can be calculated as,
[tex]\begin{aligned}{h^2}&= {p^2} + {b^2}\\{h^2} &= {6^2} + {5^2}\\{h^2} &= 61\\h &= \sqrt {61}\\\end{aligned}[/tex]
Therefore, the distance between [tex]B{\text{ and }}C[/tex] is [tex]\sqrt {61}[/tex] units.
Thus, option C is partially correct , the answer must be under a square root as [tex]\sqrt {61}[/tex] units.

Identify a pattern in the given list of numbers. Then use this pattern to find the next number 5,9,14,20,27,35,____
Answer:
the answer is 44
Step-by-step explanation:
the pattern is 4,5,6,7,8 so then you would add 9 to get 44
Final answer:
The pattern in the given list of numbers is that each number increases by consecutively larger increments of 1. By continuing this pattern, adding 9 to the last number (35), we determine the next number in the series to be 44.
Explanation:
The given list of numbers is 5, 9, 14, 20, 27, 35, and we are asked to identify the pattern to find the next number in the series.
Let's look at the differences between consecutive terms: 9 - 5 = 4, 14 - 9 = 5, 20 - 14 = 6, 27 - 20 = 7, 35 - 27 = 8.
We can see that with each step, the difference increases by 1. This pattern suggests that the next difference should be 9.
To find the next number, we add 9 to the last number in the series: 35 + 9 = 44. Therefore, the next number in the series is 44.
Point Y is the midpoint of segment XZ. If XY = 2(3x +1) and YZ = 5x + 22, find the value of x. x = 20 x = 24 x = 18 x =11
Answer:x=20
Step-by-step explanation:
2(3x+1) = 6x+2
since xy and yz are the parts of a midpoint they are equal to eachother
so 6x+2=5x+22
if you subtract 5x from both sides you get x+2 = 22 then you subtract 2 from both sides so you have x=20
