Answer:
a6 = 18,000
Step-by-step explanation:
a1 = 6
an = 5a(n-1)
a2 = 5a(2-1) = 5a1 = 5•6 = 30
a3 = 5a(3-1) =5a2 = 5•30 = 150
a4 = 5a(4-1) = 5a3 = 5•150 = 720
a5 = 5a(5-1) = 5a4 = 5•720 = 3600
a6 = 5a(6-1) = 5a5 = 5•3600 = 18000
2. A botanist grew a variety of hibiscus with spots on the petals. Below is a list of the number of
spots on a random sample of flowers,
7, 11, 3, 11, 7, 9, 5, 5, 7, 5,5
Assuming that the sample was representative of all of the flowers, what was the mode of the
number of spots on a flower?
O A. 9
OB. 5
O C. 7
O D. 6.82
Answer:
5
Step-by-step explanation:
The mode is the number that appears the most in a set.
5 appears 4 times
7 appears 3 times
11 appears 2 times
9 and 3 appear 1 time
5 is the mode as it appears the most amount of times.

The triangles below are similar. What is the value of x ?
Answer:
Step-by-step explanation:
Since triangle ADE and triangle ABC are similar, that means their sides are proportional, thus we get the equation
[tex]\frac{AD}{AB} =\frac{DE}{BC}[/tex]
[tex]\frac{2}{6} = \frac{x}{12}[/tex]
[tex]6x = 24\\x=4[/tex]

Answer:
D) f (-1) (x) = x³-12
Step-by-step explanation:
∛x+12
Interchange the variables and solve for y
∛y +12 =x
(∛x+12) ³= x³
y+12 = x³
y= x³-12
f (-1) (x) = x³-12
Candice knows it is made entirely from one metal. She is not sure if it is copper, silver or gold. Her bracelet has a mass of approximately 18 g. Metal Density (g/cm) Copper 8.96 Silver 10.49 Gold 19.32 Convince Candice that her bracelet is made from silver. You must show all your working.
Candice's bracelet is made from silver because the volume of her bracelet is; 1.72cm³
Density, Mass and VolumeBy definition, the density of an object is the ratio of its mass per unit volume.
Density = Mass/Volume.Hence, for silver;
10.49 = 18/Volume.Volume = 18/10.49Volume = 1.72cm³.

Answer:
C. II only
Step-by-step explanation:
A rational number is a terminating decimal, meaning that the decimal does not go on forever.
I and III have ellipses (...) after them, meaning they are a nonterminating decimal, so these are irrational numbers.
II has a decimal that ends, so II is a rational number.

m varies directly as n. m = 120 when n = 8. What is m when n = 11?
A. 15
B. 95
C. 135
D. 165
Answer:
D.165
Step-by-step explanation:
m varies directly with n
m = 120 when n = 8
given this we want to find m when n = 11
we can use the direct variation equation to do so
y = kx but instead of x and y values we have values of m and n
m = kn
the constant is k, we need to solve for it, we can do so by plugging in m = 120 and n = 8
120 = k(8)
solving for k
divide both sides by 8
k = 15
the constant of variation is 15
now we want to find m when n = 11
using the direct variation equation we acquire
m = 11(15)
multiply 11 and 15
m = 165
the answer is D
3. Use the polynomial 12x^4 y^2 + 30x^3 y to answer the following questions?
Part A: What is the GCF of the polynomial expression?
Part B: Write the polynomial expression in an equivalent form by factoring out the GCF
Answer:
[tex]\huge\boxed{GCF:6x^3y}[/tex]
[tex]\huge\boxed{Factored: 6x^3y(2x+5)}[/tex]
Step-by-step explanation:
Look at both terms separately, and isolate each "part."
i.e. 12x^4y^2 becomes 12, x^4, y^2
So the problem becomes:
12, x^4, y^2 and
30, x^3, y^1
Then, find the GCF of each term,
30 and 12 - 6
x^4 and x^3 - x^3
y^2 and y^1 - y^1

How much will the monthly payment be for a new car priced at $14,350 if the current finance rate is 36 months at 3. 16%? Include financing the 8% TT&L and make a 30% down payment.
a)$279. 03
b)$325. 44
c)$305. 48
d)$436. 40
e)$398. 61
The monthly payment for the new car is; Choice A; $279. 03
PercentagesAfter the down payment of 30% and financing the 8% TT&L is made; it follows that;
The rest of the payment is;
$14,350(1 - 0.38)$14,350(0.62)Hence, $8,897 is the payment made over the course of the duration at a finance rate of 3.16%.
Ultimately, the monthly payment is; $8,897 × 0.0316 = $279.03

Why did Americans begin to change their mind about the war?
Answer:
Step-by-step explanation:
When WWI began in Europe in 1914, many Americans wanted the United States to stay out of the conflict. So they won't get dragged into it plus it would cause drama between them and Europe and it would go on and on until the other team wins.
Answer:
What war? If your referring to WW2 then because they were provoked from the japanese. IF they attacked the US, then they feared that later in the future they will be overrun when germany plus japan imperialism will be too strong for them.
Under the translation by the vector (4,−3), the image coordinates of the vertices for △ are ′(−1,3),′(3,−4),′(4,0). Identify the pre-image coordinates.
Answer:
see explanation
Step-by-step explanation:
to find the pre- image coordinates use the opposite vector to translate the image coordinates.
the opposite vector to (4, - 3 ) is (- 4, 3 ) , then
(- 1, 3 ) → (- 1 - 4, 3 + 3 ) → (- 5, 6 )
(3, - 4 ) → (3 - 4, - 4 + 3 ) → (- 1, - 1 )
(4, 0 ) → (4 - 4, 0 + 3 ) → (0, 3 )
Answer:
(3, - 4 ) → (3 - 4, - 4 + 3 ) → (- 1, - 1 )
(4, 0 ) → (4 - 4, 0 + 3 ) → (0, 3 )
Step-by-step explanation:
to find the pre- image coordinates use the opposite vector to translate the image coordinates.
the opposite vector to (4, - 3 ) is (- 4, 3 ) , then
(- 1, 3 ) → (- 1 - 4, 3 + 3 ) → (- 5, 6 )
(3, - 4 ) → (3 - 4, - 4 + 3 ) → (- 1, - 1 )
(4, 0 ) → (4 - 4, 0 + 3 ) → (0, 3 )
Hence, the correct answers are (3, - 4 ) → (3 - 4, - 4 + 3 ) → (- 1, - 1 ),
(4, 0 ) → (4 - 4, 0 + 3 ) → (0, 3 )

What is an
equation of the line that passes through the points (6, -7) and (4, -6)?
Answer:
The equation is y = [tex]\frac{-1}{2}[/tex] * x - 4
How to find the slope: [tex]\frac{Rise}{Run}[/tex] = [tex]\frac{-1}{2}[/tex] (since the rise is going down by 1 unit and the run is 2 units to the right)
How to find the y-intercept: You draw a line that go through the 2 points until it touches the y-axis and that is your y-intercept
Answer:
x+2y+8=0
Step-by-step explanation:
The equation of straight line passing through the given points
(x 1,y1) = (6,-7)
(X2,y2)=(4,-6)
is given by following formula
y-y1={(y2-y1)/(x2-x1)}×(x-x1)
y+7={(-6+7)/(4-6)}×(x-6)
y+7={1/(-2)}×(x-6)
-2y-14=x-6
0=x+2y-6+14
x+2y+8=0
This is the required equation for line passing through (6,-7) and (4,-6)
