How to determine the simplest radical form?The points are given as:
(-2,3) and (6,-4).
The distance is calculated using
d = √(x2 - x1)^2 + (y2 - y1)^2
This gives
d = √(-2 - 6)^2 + (3 + 4)^2
Evaluate
d = √113
Hence, the simplest radical form of (-2,3) and (6,-4). is d = √113

Find the sum of each finite arithmetic series. 7+14+21+ . . . . . . +105
The sum of the given finite arithmetic series 7+14+21+ . . . . . . +105 is S(5) = 840
The formula for the nth term in an arithmetic series is given by:
a(n) = a(1) + (n-1) . d
Where:
a(1) = the first term
d = the common difference = a(n) - a(n-1)
The given arithmetic series:
7+14+21+ . . . . . . +105
We can infer that:
a(1) = 7
d = 14 - 7 = 7
Find n that lead to a(n) = 105 by substituting a(1) = 7 and d = 7 into the formula:
a(n) = a(1) + (n-1) . d
105 = 7 + (n-1) . 7
105 = 7n
n = 15
Use the sum formula for n = 15.
S(n) = n/2 [a(1) + a(n)]
S(15) = 15/2 (7 + 105)
S(15) = 15 . 56 = 840

Use the given statement to find the measure of numbered angle.
∠6 and ∠ 8 are; complementary m ∠8=47 .
∠6 = 43°
If two angles sum to 90 degrees, they are said to be complementary angles. In other terms, a right angle is created when two complementary angles are combined (90 degrees). Angles 1 and 2 are complementary if their total of angles equals 90 degrees (i.e., ∠1 + ∠2 = 90°), and as a result, they are referred to as each other's complements.
Now as per the question the given angle is
∠8 = 47°
It is also given that ∠6 and ∠8 form are complementary angles. Therefore it means that the sum of both the angles will be 90°
∠6 + 47° = 90°
Now subtracting 47 from both sides we will get :
∠6 = 90 - 47 = 43°
Therefore, ∠6 = 43°

When Rachel stands next to her cousin, Rachel's shadow is 2 feet long and her cousin's shadow is 1 foot long. If Rachel is 5 feet 6 inches tall, how tall is her cousin?
When measuring height, it is necessary to represent both the vertical position and the separation between the minimum and maximum place or location. Rachel is 5 feet 6 inches tall, the tall is her cousin exists 2 feet 9 inches.
What is meant by tall?In math, tall can be defined as the vertical distance from the top to the base of the object. Tall is the distance between an object's highest and lowest points.
The measurement of an object's height from the base to the top is known as tall. It is sometimes referred to as altitude in geometry. The vertical distance between the lowest and highest point is measured. In coordinate geometry, it is often the measurement along the y-axis of an object.
Rachel/Cousin = Rachel's shadow / Cousin's shadow
5 feet 6/x = 2/1
simplifying the above equation, we get
5ft 6 = 2x
x = 5ft 6/2
x = 66in/2
x = 33 in
x = 2ft 9inch
Therefore, the value of x = 2ft 9inch.

If the faster stone takes 10.0 s to return to the ground, how long will it take the slower stone to return? t = nothing s
The slower stone will take 3.33 seconds if the faster stone takes 10s to return to the ground.
What is linear acceleration?It is defined as the rate of change in linear velocity with respect to time. It is also known as linear acceleration.
From the motion equation:
s = ut + at²/2
From the data given:
s = 0
0 = 3u(10) - 9.8(10)²/2
After solving:
u = 16.33 m/s
To calculate for time:
s = ut + at²/2
s = 0
u = 16.33
0 = 16.33t + 9.8t²/2
t = 3.33 seconds
Thus, the slower stone will take 3.33 seconds if the faster stone takes 10s to return to the ground.

x = 3
Step-by-step explanation:
2(4 + 3x) + 6 = 32 ( subtract 6 from both sides )

4 + 3x = 13 ( subtract 4 from both sides )
3x = 9 ( divide both sides by 3 )
x = 3
As a check
substitute x = 3 into the left side of the equation and if value obtained is equal to the right side (32) then it is a solution to the equation.
2(4 + 3(3)) + 6

Find a₁ for a geometric sequence with the given terms. a₅ = 112 and a₇ = 448
The first term of the geometric sequence is a(1) = 7.
The nth term of a geometric sequence is given by:
a(n) = a(1) . rⁿ⁻¹
Where:
a(1) = the first term
r = ratio
Parameter given in the problem:
a(5) = 112
Plug n = 5 into the formula
a(1) . r⁵⁻¹ = 112
a(1) . r⁴ = 112 ....... (1)
a(7) = 448
Plug n = 7 into the formula
a(7) = a(1) . r⁶
448 = a(1) . r⁶ ..... (2)
Divide (2) by (1)
448 : 112 = r⁶ : r⁴
4 = r²
Since r² = 4, then r⁴ = ( r² )² = 4² = 16.
Substitute r⁴ = 16 into equation (1):
