The first 4 terms of the sequence are -5, -2, 1, 4
What is a sequence?
A sequence is a predetermined arrangement of connected actions, occurrences, or objects that occur after one another. A sequence is an ordered collection of enumerated objects in mathematics where repeats are permitted. A sequence can also be seen as a set as it contains members as well.
Solution Explained:
Given,
[tex]a_{1} = -5\\a_{n} = a_{n-1} + 3[/tex]
Assuming n ≥ 2, we get
[tex]a_{2} = a_{n-1} + 3\\a_{2} = a_{2-1} + 3 \\a_{2} = a_{1} + 3\\a_{2} = -5 + 3\\a_{2} = -2[/tex]
[tex]a_{3} = a_{n-1} + 3\\a_{3} = a_{3-1} + 3 \\a_{3} = a_{2} + 3\\a_{3} = -2 + 3\\a_{3} = 1[/tex]
[tex]a_{4} = a_{n-1} + 3\\a_{4} = a_{4-1} + 3 \\a_{4} = a_{3} + 3\\a_{4} = 1 + 3\\a_{4} = 4[/tex]

Given,you rotate a triangle 270° counterclockwise about the origin.
Then you translate its image 2 units right and 1 unit down.
The vertices of the final image are (0, 2), (8,-1), and (5,-2).
we are asked to find the vertices of the original triangle =?
Before translating the image of final image 2 units right and 1 unit down.
the vertices of the triangle is:
(0-2,2+1) → (-2,3)
(8-2,-1+1) → (6,0)
(5-2 , -2+1) → (3,-1)
{translate the final image 2 units left, 1 unit up again}
then before rotate 270° counterclockwise.
the vertices of the triangle is:
(-2,3) → (-3,-2)
(6,0) → (0,6)
(3,-1) → (1,3)
{rotate 270° clockwise again }

The total height gained from start to finish is 58m and the average gradient from start to finish is 29/210
What is an average gradient?
The gradient of a straight line drawn between two points is the average gradient between the two points.
Here, we have
A road has a gradient of 1/5 for 90 m.
Horizontal section 130 m long
The final section has a gradient of 1/5 for 200 m.
First, we will find the total height gained from start to finish
Total height from start to finish = 90 ×1/5 +200 × 1/5
= 18 + 40
Total height from start to finish =58 m
The average gradient from start to finish = 58/(90 + 130 +200)
= 58/420
= 29/210
Hence the total height gained from start to finish is 58m and the average gradient from start to finish is 29/210

How do you find the average of 1 to 100?.
The first 100 natural numbers are 1,2,3,...,100 is 50.5.
An average is a single number chosen to represent a group of numbers; it is typically the sum of the numbers divided by the number of numbers in the group. The average of the numbers 2, 3, 4, 7, and 9 is, for instance, 5.
We know that the sum of the first n natural numbers is = 2n(n+1)
Therefore, the sum of the first 100 natural numbers is = 2×100(101)
=200(101)=20200
Hence, the sum of the first 100 natural numbers is = 20200 = 101

Based on the charged amount, Lupita drove 8.76 miles.
Let us assume the number of miles rode bh Lupita be x. Forming the equation now -
Total charge = flat rate + cost per mile × number of miles
Keep the values in above mentioned equation to find the value of x
40.03 = 6.75 + 3.20×x
Rewriting the equation with respect to x
3.20x = 40.03 - 6.75
3.20x = 33.28
Shifting 3.20 to Right Hand Side of the equation

Only y = - 2x - 3...(iv) and y = (1/2)x...(v) are perpendicular to each other as the negative reciprocal of - 2 is 1/2.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know lines that are perpendicular to each other have a slope that is negative reciprocal of each other.
The given lines are,
y = 2x + 8...(i)
y = 2x...(ii)
2y = (1/2)x + 4.
y = (1/4)x + 2...(iii)
y = - 2x - 3...(iv).
y = (1/2)x...(v)

What is probability?
The ratio of positive outcomes to all possible outcomes of an event is known as the probability.
Formula for probability = favourable outcomes/ total outcomes
Main body:
if 4 coins are tossed , total no. of outcomes = 2⁴ = 16
In a toss there are 2 outcomes T or H
so, Probability of getting Head = 1/2
The probability of getting at least 1 head = 1- probability of getting no heads
⇒1 - Probability of getting tail in 4 tosses
⇒ 1 - (1/2)⁴

Step-by-step explanation:
You want the area of a figure composed of a rectangle 100 ft long and 10 ft wide with semicircles of diameter 10 ft at each end.
Rectangle AreaThe area of the rectangle is ...
A = LW
A = (100 ft)(10 ft) = 1000 ft²
Circle AreaThe two half-circles have the area of a whole circle with radius 5 ft.
A = πr²
A = π(5 ft)² = 25π ft² ≈ 78.5 ft²
Total AreaThe area of the figure is the sum of the areas of its parts:
total area = rectangle area + circle area

Valentina should use a gear on the back wheel that has larger diameter to be more efficient
Further explanations to why using larger diameterThe problem deals with circumference of the wheel.
Circumference is a function of diameter such that: A larger wheel will have a larger circumference and a smaller wheel will have a smaller circumference
The wheel is assumed to be a circle and equation of circumference of a circle is pi * diameter
Gear has the function of rotating the wheel when a gear makes a initiates one revolution of the wheel
say wheel x, diameter = 5 and wheel y, diameter = 10
distance covered by one revolution = circumference
circumference of x = pi * 5 = 5pi
circumference of y = pi * 10 = 10pi
comparing both shows that wheel y will cover double the distance of x hence more efficient.

Given that a photocopier takes 8s to make 20 copies and we need to find out how long would it take to make 45 copies .
This can be solved using Unitary Method as ,
To make 20 copies it takes 8 s.
To make 1 copy it would take 8/20 s
Hence to make 45 copies it would take 8/20*45 = 18s
And we are done!
Answer:
45 copies = 18 seconds
Step-by-step explanation:
Time taken to make 1 copy,
→ Total time ÷ Total copies
→ 8 ÷ 20
→ 8/20 seconds
Then the time taken for 45 copies,
→ 45 × (8/20)
→ (45 × 8)/20
→ 360/20
→ 18 seconds
Hence, time taken is 18 seconds.

Answer:
6\sqrt3
Step-by-step explanation:
Since 30-60-90 tri, small side is 6.
This means x=[tex]6\sqrt3[/tex]
Answer:
[tex]x = 6\sqrt{3}[/tex]
Step-by-step explanation:
Utilize the trigonometric ratio cosine.
[tex]\cos(30\textdegree ) = \dfrac{x}{12}[/tex]
Solve for x by multiplying both sides by 12.
[tex]12\cos(30\textdegree ) = x[/tex]
[tex]12\left(\dfrac{\sqrt{3}}{2} \right) = x[/tex]
[tex]x = 6\sqrt{3}[/tex]

How can the population size be calculated?The size of a population refers to its total number of members. The average person count per unit of area or volume is referred to as population density.
a. The formula to solve the question is as follows:
y = 123.1(1.069)x.
Hence x is the amount of time that was passed.
2001 - 1998 = 3y = 123.1 (1.069)³y
= 123.1 x 1.2216115y = 150.4
In 2001, the school is expected to have 150000 students enrolled.
b. 2018
The distinction x, or the variation between the years we are to calculate, must be considered:
x = 2018 - 1998
= 20.y = 123.1 x (1.069)²⁰y
= 123.1 x 3.798y
= 467.5468

Calculate height of lighthouse pls :) thx
The height of lighthouse is 72.54
Given,
In the question:
To see the figure:
To find the height of lighthouse.
Now, According to the question:
In Triangle ABD
tan 20° = [tex]\frac{h}{20 + x}[/tex]
0.36 = [tex]\frac{h}{20 + x}[/tex]
=> (20 + x)0.36 = h
=> 0.72 + 0.36x = h
=> x = [tex]\frac{h - 72}{0.36}[/tex] .....(1)
In Triangle ABC
tan 34° = h/x
=> 0.67 = [tex]\frac{h}{\frac{h-72}{0.36} }[/tex]
=> 0.67 = 0.36/h - 72
=> 0.67 (h - 72) = 0.36
=> h - 72 = 0.54
=> h = 0.54 + 72
=> h = 72.54
Hence, The height of lighthouse is 72.54
