Write the first four terms of a sequence given the recursive rule below:
f(n)=2\cdot f(n-1)+3\;for\;all\;n\geq2\;and\;f(1)=7f(n)=2⋅f(n−1)+3foralln≥2andf(1)=7
The first four terms of the sequence are 7, 17, 37 and 77, respectively.
How to determine the first four terms of a sequence by a recursive formula
Sequences can be generated by using recursive formulas, that is, formulas that are in terms of the previous elements of a sequence. Herein we find a case of sequences by using recurrence formulas, whose procedure is shown below:
n = 1
f(1) = 7
n = 2
f(2) = 2 · f(1) + 3
f(2) = 17
n = 3
f(3) = 2 · f(2) + 3
f(3) = 37
n = 4
f(4) = 2 · f(3) + 3
f(4) = 77
The first four terms of the sequence are 7, 17, 37 and 77, respectively.

the number of pigs: the number of goats = 11:3
If there are 12 goats in the field, how many pigs are there?
Answer:
44pigs
Step-by-step explanation:
12/3=4.
4*11=44
The ratio shows how many times one value is contained in another value.
The number of pigs is 44.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
The number of pigs: the number of goats = 11:3
Let the number of pigs = 11x
Let the number of goats = 3x
The number of goats = 12
This means,
3x = 12
Divide 3 on both sides.
x = 12/3
x = 4
Now,
The number of pigs:
= 11x
= 11 x 4
= 44
Thus,
The number of pigs is 44.

Prior to an election, 6,504 people vote in the advance polls for a riding. On election day, thepolling stations for that riding record an average of 407 voters per hour. How long were thepolls open on election day, if a total of 10,167 people voted in that riding?
**USE LET STATEMENTS, AND THEREFORE STATEMENTS**
The number of hours the polls open on the election day was 9 hours
From the question, we are to determine how long the polls opened on the election day
From the given information,
6,504 people vote in the advance polls for a riding prior to the election
and
A total of 10,167 people voted in that riding
Thus,
The number of people that voted on the election day = 10167 - 6504
Number of people that voted on the election day = 3663
Also, from the given information
The polling stations for the riding record an average of 407 voters per hour
Then,
Number of hours the polls open on election day = Number of people that voted on the election day ÷ Average number of voters per hour
Number of hours the polls open on election day = 3663 ÷ 407
Number of hours the polls open on election day = 9 hours
Hence, the number of hours the polls open on the election day was 9 hours

Step-by-step explanation:
Alma is choosing a new smartphone and cellular service plan. let p be the phones price in dollars, m be the cost of the selected plan in dollar per month, and c be alma's total cost in dollars after time t, measured in months of service. write an equation that expresses c in terms of p, m, and t. then solve your equation for t.
The equation which expresses c in terms of p, m and t as in the task content is; c = mt + p and the solution of the equation for t is; t = (c -p)/m.
What is the equation of the situation such that c is expresses in terms of p, m and t?It follows from the fact that the rate of change, m is constant in the situation described. Hence, the equation is a linear equation.
On this note, the required equation which represents total cost, c in terms of p, m and t can be written as;
C = mt + p.
Hence, to solve the equation above for t;
Subtract p from both sides so that;
c - p = mt
Divide both sides by m;
(c - p)/m = t.
Ultimately, The equation which expresses c in terms of p, m and t as in the task content is;
c = mt + p
and the solution of the equation for t is;
t = (c -p)/m.

if the point P(-4/5,y) lies on the unit circle and P is in the third quadrant, what does y equal
The value of y on the unit circle is y =-3/5
What is a circle?A circle is defined as the locus of a point such that it is equidistant from a fixed point.
The equation of a circle with center at the origin is given by x² + y² = r² where r = radius of circle
What is a unit?A unit circle is a circle with radius, r = 1.
So, the equation of a unit circle is x² + y² = 1
How to find the value of y on the unit circle?Given that the point P(-4/5, y) lies on the unit circle, and P is int he third quadrant, making y subject of the formula in the equation for unit circle, we have
y = ±√(1 - x²)
Substituting x = -4/5 into the equation, we have
y = ±√(1 - x²)
y = ±√(1 - (-4/5)²)
y = ±√(1 - 16/25)
y = ±√[(25 - 16)/25]
y = ±√[9/25]
y = ±3/5

Not all rational numbers a and b satisfy the equation |a+b|=|a|+|b|.

A kitten has 5 claws on its paw, a chicken has 4. there are 57 kittens and chickens in the yard and they all have 768 claws. how many kittens and chickens are in the yard?
Using algebraic expressions and equation, there are 26 kittens and 31 chickens in the yard.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
Given that there are 57 kittens and chickens in the yard, we can express this as:
x + y = 57 ⇒ x = 57 - y (equation 1)
where x = number of kittens
y = number of chickens
If a kitten has 5 claws on each of its 4 paws, and a chicken has 4 claws in each of its 2 feet, and they all have 768 claws, then
5(4)x + 4(2)y = 768 ⇒ 20x + 8y = 768 (equation 2)
Substitute equation 1 to equation 2 and solve for y.
20(57 - y) + 8y = 768
1140 - 20y + 8y = 768
-12y = -372
y = 31
number of chickens = 31
Substitute the value of y in either of the two equations and solve for x.
x = 57 - y
x = 57 - 31
x = 26
number of kittens = 26

In 2010, the population of a city was 228,000. From 2010 to 2015, the population grew by 7.7%. From 2015 to 2020, it fell by 4.2%. To the nearest 100 people, what was the population in 2020?
The population in the city in 2020 to the nearest 100 is 235242.65.
The population of the city was 228,000 in the year 2010.
From 2010 to 2015, the population grew by 7.7%.
The population decreases by 4.2 % from 2015 o 2020.
Initially, the population of the city is 228,000.
From 2010 to 2015,
The city's population increased by 7.7%.
7.7% of 228,000 = ( 7.7 / 100) × 228,000 = 17556
The population of the city from 2010 to 2015 = 228,000 + 17556 = 245556
From 2015 to 2020,
Now, the city's population decreases by 4.2%.
4.2% of 245556 = ( 4.2 /100) × 245556 = 10313.352.
Therefore,
The population of the city in the year 2020 = 245556 - 10313.352 = 235242.648
Therefore, the population in the year 2020 to the nearest 100 is 235242.65.
