Find the 17 th term of each sequence. a₁₆=18, d=5
The 17 th term of the Arithmetic Progression (AP) is found to be a₁₇ = 26.
What is the AP sequence for arithmetic progression?In Arithmetic Progression (AP), the difference between the two numerical orders is a constant value. Arithmetic Sequence is another name for it.
We'd come across a few important words in AP, denoted as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)The AP may also be characterized in concepts of common distinctions, as shown below.
The following is the formula for determining an AP's n-th term: an = a + (n − 1) × dThe arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, as per the given data in the question;
16th term; a₁₆ = 18
Common difference; d = 5
Then, the 17th term would be calculated as;
Use the common difference formula;
d = a₁₇ - a₁₆
a₁₇ = a₁₆ + d
a₁₇ = 21 + 5
a₁₇ = 26
Therefore, the value of the 17th term of a AP is found as 26.

A squirrel can run a short distance at a rate of 4 3/4 miles in 15 minutes. A fox can run a short distance at a rate of 21 miles in half an hour. Which is faster, and how much faster in miles per hour?
35 mph= .58 of a mile per minute
21 miles in 30 minutes= .7 of a mile per minute
if you multiply by 60 to see the distance in the same amount of time:
rabbit: 35 mph
fox: 42
So the fox would run a greater distance in the time given. Hope this helps!
Find the missing term of each arithmetic sequence.... 5, .. , 21,...
The missing terms of an arithmetic progression (AP) are -3, 5, 13, 21, 29.
What is meant by arithmetic progression (AP)?An arithmetic progression (AP) is a pattern in which each successive term has the same distinctions.
Each term in an arithmetic progression (except the first) is deduced by adding a specific range to the term preceding the first.The following arithmetic progression concepts are most often used to solve various AP problems for the initial term 'a' of an AP together with the common difference 'd.'The most common difference AP is 'd': d = a2 - a1 = a3 - a2 = a4 - a3 =...... = a - an-1. nth term of an AP: an = a + (n - 1) dThe sum of an AP's n terms is; Sn = n/2(2a+(n-1)d) = n/2(a + l), where l is the final term of the AP.The arithmetic sequence.... 5, .. , 21,...
There are total 5 terms in the series.
Let the initial term be 'a₁'.
Let the second term be 'a₂' = 5.
Let the third term be 'a₃'.
Let the fourth term is be 'a₄' = 21.
And final, the fifth term be 'a₅'.
The common difference of the AP are same. so,
d = a₃ - a₂ ........(equation 1)
d = a₄ - a₃ .......(equation 2)
Thus, equate the two formed equation;
a₃ - a₂ = a₄ - a₃
Substituting the values;
a₃ - 5 = 21 - a₃
Simplify the above equation;
a₃ = 26/2
a₃ = 13.
Put the value in equation 1 and find the common difference.
d = a₃ - a₂
d = 13 - 5 = 8
So, the first term will be;
d = a₂ - a₁
a₁ = a₂ - d
a₁ = 5 - 8
a₁ = -3
Now, the fifth term will be;
a₅ = a₄ + d
a₅ = 21 + 8
a₅ = 29.
Therefore, the arithmetic sequence of the AP formed as -3, 5, 13, 21, 29.

The length of an animal's stride is the distance between two consecutive tracks. The average stride length of a duck is about 5 inches. Write a glide reflection that can be used to predict the location of the next track for the following animal tracks.
duck
The glide reflection ( x + 2.5 , y ) is that is reflected in the line that separates the left prints from the right prints.
A glide translation is what?
A glide reflection is made up of a translation and a reflection in which the translation and the reflection are parallel to each other or the direction of the translation. A gliding reflection has opposite isometry and is -commutative.Now, let's assume that the initial position is (x , y) .
Since, the average stride length of a turkey is about 11 inches; also since the turkey has two legs, therefore, the average stride length between the two legs is as shown below:
average = 5/2 = 2.5
Thus, the glide reflection is ( x + 2.5 , y )

Write each number as a percent.
1.23
.
Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100.
The number 1.23 as a percentage is 123 %.
What is a percentage?A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The percent sign, %, is frequently used to indicate it. There is no unit of measurement for a percentage. It is a dimensionless number (pure number).
Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage.
Let the number be 1.23
To find percentage multiply it by 100, we get
So, 1.23 × 100 = 123 %
Therefore, the number 1.23 as a percentage is 123 %.

Suppose ∠4 and ∠ 5 form a linear pair.
If m ∠1=2 x, m ∠2=3 x-20 , and m ∠3=x-4 what is m ∠3 ?
A. 26° B. 28° C. 30° D. 32°
Option C: The value of m ∠3 is 30° (C).
As per the question, ∠4 and ∠5 form a linear pair. Therefore the sum of ∠4 and ∠5 is 180° so, so the sum of the remaining m∠1,m∠2, and m∠3 angles is 180°.
So, m∠1 + m∠2 + m∠3 + m∠4 + m∠5 = 360° (as the total angle is 360°).
Now, m∠4 + m∠5 = 180°(∠4 and ∠5 form a linear pair). (∴ m∠1 + m∠2 + m∠3 = 180°). Now we will put the given values and will try to find out the value of x.
2x + (3x-20) + (x-4) = 180
[m ∠1 = 2 x, m ∠2 = 3 x-20, and m ∠3 = x-4]
or,
6x-24=180
or,
6x = 180+24
or,
6x = 204
or, x = 204/6
or. x = 34
As per the question we have to find out the value of m ∠3.
m ∠3 = 34° - 4° = 30° (as x = 30°)
So, m ∠3 is 30°.
If ∠4 and ∠ 5 form a linear pair. And, m ∠1=2 x, m ∠2=3 x-20, and m ∠3=x-4, the value of ∠3 is 30°. Therefore, Option C is the correct answer.

Because a straight line may be drawn continuously between any two points, they are always collinear. There can be a collinear relationship from three or more points, although it is not necessary.

Find a₁ for each arithmetic series. S₈ =440 and d=6
An arithmetic sequence (AP) is a progression in which the difference (called the tolerance) between two consecutive terms in the passage/progression is constant.
Therefore, the expression for the nth term is,
an = a₁ + (n − 1) d
and in general
an = am + (n - m) d.
where d is the difference.
For an arithmetic series with initial term a₁ and difference between terms of d
an = a₁ + (n − 1) d
We are given some of the values,
d = 6 and
S8 = 440
So, we will put the values in the formula and calculate the desired value,
a1 = 440 = a1 + ( 8 - 1 ) * 6 = a1 + 42
a1 = 440 - 42 = 398.

Exterior Angle Inequality Theorem
According to the exterior angle inequality theorem, the measure of any exterior angle of a triangle is greater than the measure of either of the opposite interior angles. The adjacent interior angle and the exterior angle are supplementary. A triangle's exterior angles add up to 360º.
A triangle's exterior angle is always greater than its two remote interior angles.

Can you help me in identifying m?
The length of the side m are obtained using the theorem of Pythagoras and proportional triangles to give;
a) m ≈ 28.4
b) m ≈ 12.09
c) m ≈ 9.38
Which theorem can be applied to find the value of m?a) The given triangle, is a right triangle.
The length of the legs of the triangle are; 33 and 56.
According to Pythagorean theorem, the length of the hypotenuse side, l, is therefore;
l = √(33² + 56²) = 65
From the formula for the area of a triangle, we have;
Area of a triangle, A, equals half the base length multiplied by the height.
A = 0.5 × Base length × Height
For the right triangle, we have;
A = 0.5 × Leg 1 × Leg 2
Which gives;
A = 0.5 × 33 × 56 = 924
However;
A = 0.5 × l × m
Where;
l = The hypotenuse = The base length = 65
m = The height of the triangle
Which gives;
A = 0.5 × 65 × m = 924
m = 924/(0.5 × 65) ≈ 28.4
m ≈ 28.4b) The side m is parallel the 14 units long side.
The proportion the side m divides a side of the triangle = 3 and 19
Given that the triangle formed by m is proportional to the larger triangle, we have;
m/14 = 19/(19+3)
m = 14 × 19/(19+3) ≈ 12.09c) From the proportionality of similar triangles, we have;
m/16 = 17/(14+15)
m = 16×17/(14+15) ≈ 9.38Learn more about the proportionality of similar triangles here:
