4.Solveby any algebraic method. Work must be shown.
Answers
Answer:
The test has 8 questions of 2 points, as well as 16 of 4 points and 4 of 5 points.
Step-by-step explanation:
Since, on a 28-question test, there are 2-point questions, 4-point questions, and 5-point questions, the test is worth a total of 100 points and there are twice as many 2-point questions as 5- point questions on the test, to determine how many 2-point questions are on the test, the following calculation must be performed:
18 x 2 + 9 x 5 + 1 x 4 = 36 + 45 + 4 = 85
16 x 2 + 8 x 5 + 4 x 4 = 32 + 40 + 16 = 88
14 x 2 + 7 x 5 + 7 x 4 = 28 + 35 + 28 = 91
12 x 2 + 6 x 5 + 10 x 4 = 24 + 30 + 40 = 94
10 x 2 + 5 x 5 + 13 x 4 = 20 + 25 + 52 = 97
8 x 2 + 4 x 5 + 16 x 4 = 16 + 20 + 64 = 100
Thus, the test has 8 questions of 2 points, as well as 16 of 4 points and 4 of 5 points.

The series C: 625 – 125 + 25 – 5 + … converges. Explanation given.
What is common ratio?The distance between each number in a geometric series is known as the common ratio. The ratio between two consecutive numbers, or a number divided by the number before it in the sequence, is known as the common ratio since it is the same for all numbers or common.
Given series:
A: 9 + 81 + 729 + …
B: 1 + 0.25 + 0.0625 + 0.015625 + …
C: 625 – 125 + 25 – 5 + …
D: 8 – 16 + 32 – 64 + …
To prove convergence:
A: 9 + 81 + 729 + …
Simplifying,
9 + (9)² + (9)³+ ....
The first term = 9
The second term = (9)²
So, the ratio = 9
That means, the geometric series with common ratio
IrI = 9 > 1
So, if the common ratio of geometric series is greater than 1 then the series diverges.
B: 1 + 0.25 + 0.0625 + 0.015625 + …
Simplifying,
1 + (1/4) + 1/(4)²+ ....
The first term = 1
Second term = 0.25
Third term = 0.0625
The ratio r = 4
IrI = 4 > 1
So, if the common ratio of geometric series is greater than 1 then the series diverges.
C: 625 – 125 + 25 – 5 + …
Simplifying,
The first term = 625
Second term = 125
Third term = 25
The ratio r = -125/625 = -1/5
IrI = 1/5 < 1
So, if the common ratio of the series is lesser than 1 then the series converges.
D: 8 – 16 + 32 – 64 + …
The first term = 8
Second term = -16
The ratio = -16/8 = -2
IrI = 2> 1
So, if the common ratio of the series is greater than 1 then the series diverges.
Therefore, the series C converges.

An acre is equal to 43,560 square feet, and there are 5280 feet in a mile.
If a farm has the shape of a rectangle measuring 0.6 miles by 1.2 miles, what is the area of the farm in acres?
Answers
Answer:
=537.6 acres
Step-by-step explanation:
1 acre = 43560 ft^2
5280ft = 1 mile
Area of the farm
0.6miles×1.2miles = 3168ft×6336ft
=23,417,856ft^2

If PQRS is a kite, find m angle Q
Answers
Answer:
m<Q = 78°
Step-by-step explanation:
First, find the value of x:
7x + 2 = 10x - 31 (Non-vertex angles of a kite are congruent to each other)
Collect like terms
7x - 10x = -2 - 31
-3x = -33
Divide both sides by -3
x = 11
Find m<Q:
Sum of all angles in a kite = 360°
Therefore,
m<Q + m<P + m<S + m<R = 360°
m<Q + (7x + 2) + 124 + (10x - 31) = 360
Plug in the value of x
m<Q + (7*11 + 2) + 124 + (10*11 - 31) = 360
m<Q + 79 + 124 + 79 = 360
m<Q + 282 = 360
Subtract 282 from both sides
m<Q + 282 - 282 = 360 - 282
m<Q = 78°

Note that cotx = cosx/sinx
The expression becomes
Lim (xcotx) = Lim (xcosx/sinx)
x->0 x->0
= 0cos0/sin0
= 0/0 )(ind)
Apply l'hospital rule
= Lim d/dx(xcosx/sinx)
x->0
= lim (-xsinx + cosx)/cosx
x->0
= -0sin0+cos0/cos0
= 0+1/1
= 1/1
= 1
Hence the limit of xcotx as x tends to zero is 1
