Find the magnitude and direction of the following vector.
-F G: F<-4,0> and G(-6,-4)
According to estimates, FG has a magnitude of 2√5.
The vector direction of FG is given as = 63.43°. (angle formed in the 1st quadrant with anti-clockwise direction).
What exactly would a distance formula imply?The distance formula is used in complex numbers to show the plane in addition to its magnitude. Distance formulas can also be used to determine the actual the distances between two planes in three- and n-dimensional planes.
Now, in answer to the question posed;
F and G have coordinates of (-1,10) and (1,-12), respectively.
The formula for calculating the distance between points A and B is as follows:
FG² = (x₂ - x₁)² + (y₂ - y₁)²
FG = √[(x₂ - x₁)² + (y₂ - y₁)²]
The coordinates for the points F and G's are-
(x₁,y₁) = (-4,0) and (x₂,y₂) = (-6,-4).
Substituting the given values in the distance formula;
FG = √[(-6 + 4)² + (-4 + 0)²]
FG = √[(-2)² + (-4)²]
FG = √[4 + 16] = √20
FG = 2√5 (magnitude of the vector FG)
Estimate the direction of this same vector FG now. The angle formed by a vector with a horizontal line defines its direction.
Use one of the following formulas to calculate the direction of a vector.
tan Ф = Δy/Δx
Where, x = horizontal change
and, y = vertical change
tan Ф = (y₂ - y₁)/(x₂ - x₁)
= (-4 + 0)/(-6 + 4)
tan Ф = -4/(-2) = 2
Ф = 63.43° (angle lies with in the first quadrant with anticlockwise direction).
As a result, the distance between F and G is determined to be 2√5. (the same as the magnitude of a given vector FG).

Find x and the measure of each side.
ΔR S T is equilateral. R S is three more than four times x, S T is seven more than two times x , and T R is one more than five times x .
For given equilateral triangle ΔRST, x = 2. And the measure of each side is 11 units.
In given question,
ΔRST is equilateral triangle.
We have been given some information about sides of ΔRST.
RS is three more than four times x.
We write above statement as mathematical expression.
RS = 3 + 4x
ST is seven more than two times x.
We write above statement as mathematical expression.
ST = 7 + 2x
and TR is one more than five times x.
We write above statement as mathematical expression.
TR = 1 + 5x
We need to find the value of x.
Since ΔRST is an equilateral triangle, RS = ST = RT
⇒ 3 + 4x = 7 + 2x = 1 + 5x
Consider 3 + 4x = 7 + 2x
⇒ 4x - 2x = 7 - 3
⇒ 2x = 4
⇒ x = 2
Now we find the measure of each side.
RS = 3 + 4x
RS = 3 + 4(2)
RS = 11 units
But RS = ST = RT
So, the measure of each side is 11 units.
Therefore, for given equilateral triangle ΔRST, x = 2. And the measure of each side is 11 units.

Making C the subject of the formula, we have: C = 5(F - 32)/9.
How to Find the Subject of the Formula?Given the formula, F = 9/5C + 32, we are asked to solve the equation for C, this means we would make C the subject of the formula.
F = 9/5C + 32
Subtract 32 from both sides
F - 32 = 9/5C + 32 - 32
F - 32 = 9/5C
Multiply both sides by 5/9
5/9(F - 32) = 9/5C(5/9)
5(F - 32)/9 = C
C = 5(F - 32)/9
Therefore, making C the subject of the formula, we have: C = 5(F - 32)/9.

The grid shows the graph of the parent function. f(x)=|x| and a translated functions graph.
Write the equation for the translated graph
Answer:
f(x) = |x + 2| + 1
Step-by-step explanation:
The graph of f(x) is translated 2 units to the left and 1 unit up
A horizontal translation of 2 units results in the original function being f(x +2)
A vertical translation of 1 unit happens at f(x) + 1
Horizontal translation of 2 units left of f(x) = |x| is f(x+2) = |x + 2|
Vertical translation of 2 units up : f(x) = |x| + 1
Combined we get g(x) = |x + 2| + 1

What is an arithmetic sequence?It refers to a "series where the deviations between every subsequent term are exactly the same" (or) "each term is acquired by adding a specific number (positive, negative, or zero) to its preceding term."
We have three values of sequence:
Q(1)=4

Q(7)=13
Let us assume the sequence to be an arithmetic sequence
The n-th term of any arithmetic sequence is determined by:
[tex]a_{n}[/tex] = a+(n-1) d
Q(3)=Q(-1)+(3-1)d
7 =4+2d
2d = 3
d = 3/2
d = 1.5
Now, Q(7) = Q(1) + (-1)d
13 = 4+6 d
6d = 9
d = 9/3
d = 1.5
So, the d is the same for both terms.
Therefore, this is an arithmetic sequence.The recursive relation is given as [tex]a_{n}[/tex] = a(n-1)d.

For a geometric progression,
u3 = 4.5 and u7 = 22.78125. Find the value of the common ratio and the first term.
Answer: Ratio: 2:3
2 ==> 1st term
Step-by-step explanation:
22.78125/4.5=5.0625
5.0625^(1/(7-3))=
5.0625^(1/4)=1.5 ==> Ratio: 1:1.5 ==> 2:3
4.5 / 1.5^(3-1)=
4.5 / 1.5^2=
4.5 / 2.25 = 2 ==> 1st term
The first term (a) in the geometric progression is approximately 2.
The common ratio (r) is 1.5.
Here, we have to find the common ratio (r) and the first term (a) in the geometric progression, we'll use the formula for the nth term of a geometric sequence:
[tex]u_n = a * r^{(n-1)[/tex]
where:
[tex]u_n[/tex] is the nth term,
a is the first term,
r is the common ratio,
n is the position of the term in the sequence.
Given u3 = 4.5 and u7 = 22.78125:
For n = 3:
[tex]u_3 = a * r^{(3-1)}\\4.5 = a * r^2[/tex]
For n = 7:
[tex]u_7 = a * r^{(7-1)}\\22.78125 = a * r^6[/tex]
Now, we have two equations:
[tex]a * r^2 = 4.5\\a * r^6 = 22.78125[/tex]
Divide equation 2 by equation 1:
[tex](a * r^6) / (a * r^2) = 22.78125 / 4.5[/tex]
Simplify:
[tex]r^4 = 5.0625[/tex]
Now, take the fourth root of both sides to find the value of r:
r = √(5.0625)
r ≈ ± 1.5
Since r is the common ratio, it cannot be negative in a geometric progression.
So, the common ratio (r) is 1.5.
Now, we can find the first term (a) using equation 1:
[tex]a * r^2 = 4.5[/tex]
Substitute the value of r (1.5):
[tex]a * (1.5)^2 = 4.5[/tex]
a * 2.25 = 4.5
Divide by 2.25:
a ≈ 4.5 / 2.25
a ≈ 2
Therefore, the first term (a) in the geometric progression is approximately 2.
The common ratio (r) is 1.5.

Pablo folds a straw into a triangle with side lengths of 4x2−3 inches, 4x2−2 inches, and 4x2−1 inches. Which expression can be used to find the perimeter of the triangle, and what is the perimeter when x = 1.5?
12x2 −6; 21 inches
12x2; 27 inches
12x2 −6; 30 inches
12x2; 36 inches
The expression that can be used to find the perimeter of the triangle is P = 12x^2 - 6 and the perimeter when x = 1.5 is 21 inches.
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now it is given that,
Pablo folds a straw into a triangle with side lengths of 4x^2−3 inches, 4x^2−2 inches, and 4x^2−1 inches
Suppose the sides of the triangle are,
L = 4x^2−3 inches
B = 4x^2−2 inches
H = 4x^2−1 inches
Now since the perimeter is the sum of all the sides.
Thus, Perimeter of the given triangle is given as,
P = L + B + H
Putting the values we get,
P = (4x^2−3) + (4x^2−2) + (4x^2−1)
Expanding the brackets we get,
P = 4x^2 − 3 + 4x^2 − 2 + 4x^2 − 1
Taking alike terms together,
P = 4x^2 + 4x^2 + 4x^2 - 3 - 2 - 1
Now solving we get,
P = 12x^2 - 6
Thus is the expression for the perimeter of the triangle.
Now the perimeter when x = 1.5
Put x = 1.5 in the perimeter expression we get,
P = 12(1.5)^2 - 6
Solving we get,
P = 12*2.25 - 6
Solving we get,
P = 27 - 6
Thus we get,
P = 21 inches
this is the required perimeter when x = 1.5
Thus, the expression that can be used to find the perimeter of the triangle is P = 12x^2 - 6 and the perimeter when x = 1.5 is 21 inches.

the coordinates of point 3/10 of the way from point (-3,-8) ((12,6)
Using proportions, the coordinates of the point 3/10 of the way from (-3,-8) to (12,6) are: (1.5, -3.8).
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
We want a point C 3/10 of the way from A(-3,-8) to B(12,6), hence:
C - A = 3/10(B - A).
The x-coordinate of the point is found as follows:
x + 3 = 3/10(12 + 3)
x + 3 = 4.5
x = 1.5.
The y-coordinate of the point is found as follows:
y + 8 = 3/10(6 + 8)
y + 8 = 4.2
y = -3.8.
