Answer:
Pattern = Start at 256 and divide by 4 each time. Next number = 1.Pattern = Start at 2 multiply by 3 each time. Next number = 162In the first sequence, the next term here is 1. In the second sequence; the next term is 162.
What is arithmetic sequence?An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.
In the first sequence, 256, 64, 16, 4, ...
Consider ratio of the next term with its preceding term, so we will get the common ratio;
4/ 16 = 1/4
So, we can see that the next term of the sequence is 1/4 times the previous term.
Hence, the unknown term will be; 1/4 times of previous term.
That is , 1/4 × 4 = 1
Therefore, the next term here is 1
In the second sequence; 2, 6, 18, 54, ...
Do the same procedure as above, we will get the common ratio as :
54 / 18 = 3
Thus, the next term is 3 times the preceding term, that is :
3 × 54 = 162
Hence, the next term is 162

$1000 invested with compound interest at a rate of 15% per year for 9 years. Formula: M = P(1+ i)n Group of answer choices $3517.88 $424.36 $1519.38 $888.15 $1788.14
Answer:
Option A.
Step-by-step explanation:
Note: Let as consider, we have to find the total amount after 9 years.
It is given that,
Principal amount = $1000
Rate of compound (yearly) interest = 15% = 0.15
Time = 9 year
The formula for total amount is
[tex]M=P(1+i)^n[/tex]
where, P is principal, i is rate of interest and n is number of years.
Substituting P=1000, i=0.15 and n=9, we get
[tex]M=1000(1+0.15)^9[/tex]
[tex]M=1000(1.15)^9[/tex]
[tex]M=1000(3.5178763)[/tex]
[tex]M=3517.8763[/tex]
[tex]M\approx 3517.88[/tex]
So, the total amount after 9 years is $3517.88.
Therefore, the correct option is A.

Can someone please help me
Answer: B
Step-by-step explanation:
To find the factors, you know that they are known as the zeros. The zeros are located on the x-axis, where the graph crosses. On the graph, we see that the parabola crosses the x-axis at x=-5 and x=-1. Unfortunately, those are not displayed in our answer choices.
We know that each factor is set equal to 0 to get x=?. With this knowledge, let's make it so that we can get factors.
x=-5 [add both sides by 5]
x+5=0
Now, we see that it is a factor, (x+5).
x=-1 [add both sides by 1]
x+1=0
Now, we see that it is a factor, (x+1).
Our final answer is (x+5) and (x+1) or (x+1) and (x+5).

Now is triangles what’s the awnser to this please
Answer:
32
Step-by-step explanation:
The perimeter of a figure is the sum of all the sides.
So, add up all the sides which equals the perimeter.
And we are given that the perimeter is 66. Thus:
[tex](4z)+(5z-3)+(z-1)=66[/tex]
Combine like terms:
[tex]10z-4=66[/tex]
Add 4 to both sides:
[tex]10z=70[/tex]
Divide both sides by 10:
[tex]z=7[/tex]
So, z is 7.

What is the top of the flag pole above ground in inches?
Answer:
13ft 10.2in
Step-by-step explanation:
First let's convert 3ft to in.
3 * 12 = 36 in
Now let's find the angle
We use tangent because we know the opposite and adjacent distances.
tan x = 36/13
tan x = 2.7692
On your calculator, input the value of your tangent. Then press "inv." This should give you the angle associated with that value. The angle associated with tan 2.7692 is 70.14 degrees.
Now that we know the angle we can find the height.
We use tangent again.
tan 70.14 = x / 5 We don't know the opposite but we know the adjacent length is 5ft.
2.77 * 5 = x
13.85 ft = x
To get it in ft and inches multiply .85 by 12
.85 * 12 = 10.2
13ft 10.2in

A company makes t-shirts and their research shows that that price and demand are related linearly: p = m x + b . They know that in order to sell 5 shirts they need to set the price at $50, and in order to sell 10 shirts they need to set the price at $40. Find the linear equation relating price to demand.
Answer:
The linear equation relating price to demand is Q=-0.5*P + 30
Step-by-step explanation:
The demand for a good is the quantity of that good that the demanders are willing to purchase at a given price.
Then, the Demand Curve relates the quantity that a consumer would be willing to buy as a function of price.
You seek to determine the linear equation that relates the price to the demand Q = m * P + b where Q is the quantity demanded at a price P, and compared with the equation of the straight line y = mx + b, m is the slope and b is the ordinate to the origin.
On a line of the form y = m * x + b, the value of m, having two points, is calculated by:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
And the ordinate to the origin b is calculated, taking the value of m, replacing any of the two points (replacing any of the two because it must give the same value of b) in the expression y = m * x + b and solving its value.
In the case of Q=m*P+b, the value of m, having two points, is calculated by:
[tex]m=\frac{Q2-Q1}{P2-P1}[/tex]
Being:
Q1= 5P1= $50Q2= 10P2= $40and replacing:
[tex]m=\frac{10-5}{40-50}[/tex]
you get:
m= -0.5
So, being Q=-0.5*P+b, b is calculated by:
Replacing the point Q1= 5 and P1= 505= -0.5*50 + b → 5= -25 + b → 5+25= b → b= 30
Replacing the point Q1= 10 and P1= 4010= -0.5*40 + b → 10= -20 + b → 10+20= b → b= 30
Then, the linear equation relating price to demand is Q=-0.5*P + 30

The quantity of food required for the two cats for one day is ...
(3/4 can) + (1/2 can) = (3/4 +2/4) can = 5/4 can
Then the cost per day for cat food is ...
$5/(3 cans) × (5/4 can/day) = $25/12 /day
We note that the cost for some number of days will be the product of this factor and the number of days, rounded up to the next higher $5.
1. The cost for 60 days is ...
(60 days)($25/12 /day) = $25 × 60/12 = $125
A 60-day supply of cat food costs $125.
__
2. A 29-day supply costs ...
(29 day) × $25/12 /day = $60 5/12, rounds up to $65 for 29 days
A 30-day supply costs ...
(30 day) × ($25/12 /day) = $62.50, rounds up to $65 for 30 days
A 31-day supply costs ...
(31 days) × ($25/12 /day) = $64 7/12, rounds up to $65 for 31 days.
These costs are all the same.

Using the online regression calculator :
The regression model obtained in the form:
ŷ = mx + c is ;
ŷ = 1.792X + 52.176
Where ŷ is the predicted or dependent variable
m = 1.792 is the gradient or slope of the regression line
x = the independent variable
c = 52.176 = intercept, where the line of best fit intersects the y axis.
Given the following x values, predict ŷ
(a) x= 11.5
ŷ = 1.792(11.5) + 52.176 = 72.784
(b) x= 8.0
ŷ = 1.792(8.0) + 52.176 = 72.784 = 66.512
(c) x = 15.5
ŷ = 1.792(15.5) + 52.176 = 79.952
(d) x = 10.0
ŷ = 1.792(10.0) + 52.176 = 70.096
The predicted values are meaningful as they show are very close to the actual values of height (y). This could be attributed to the high correlation Coefficient of 0.9299 which exists between both variables

Probability of getting 4 hearts = 11/833
Eric took $7000 of his income last year and invested it, part at 7% and the rest at 9%. He earned $570 from investments. How much did he invest at each rate?
Answer:
He invested 3,000 at 7% and 4,000 at 9%.
Step-by-step explanation:
From the information given, you can write the following equations:
x+y=7,000 (1)
0.07x+0.09y=570 (2)
You can solve for x in (1)
x=7,000-y (3)
Now, you can replace (3) in (1) and solve for "y":
0.07(7,000-y)+0.09y=570
490-0.07y+0.09y=570
0.02y=80
y=80/0.02
y=4,000
Finally, you can replace the value of "y" in (3):
x=7,000-4,000
x=3,000
According to this, the answer is that he invested 3,000 at 7% and 4,000 at 9%.
