A posted list of the total charges for 1,2,3,4 , or 5 hours forms an arithmetic sequence. What is the first term and what is the common difference?
The first term of the arithmetic sequence so formed is $20 and the common difference is $10.
What is arithmetic progression?A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.
Given:
Initial fee charged by players = $20.Hourly charge = $10Maximum number of hours = $5To find: The first term and common difference of the arithmetic progression so formed.
Finding:
As the initial charge charged by the players is $20, it can be taken as the first term of the arithmetic sequence, at 0 hours; a₁ = 20
Now, since the hourly charge is $10, the given arithmetic sequence of the money charged will increase by $10 per hour; thus d = 10
The arithmetic sequence holds true for 5 hours maximum.
Thus the sequence so formed => [tex]a_n = 20 + (n - 1)10[/tex], 1 ≤ n ≤ 5.
Hence, The first term of the arithmetic sequence so formed is $20 and the common difference is $10.

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.
Hence the coordinates are: (1.5, -3.8).

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.

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

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.

Step-by-step explanation:
Differentiation is an algebraic process that finds the gradient of a curve.
At a point, the gradient of a curve is the same as the gradient of the tangent line to the curve at that point.
[tex]\boxed{\begin{minipage}{5.4 cm}\underline{Chain Rule for Differentiation}\\\\If $y=f(u)$ and $u=g(x)$ then:\\\\$\dfrac{\text{d}y}{\text{d}x}=\dfrac{\text{d}y}{\text{d}u}\times\dfrac{\text{d}u}{\text{d}x}$\\\end{minipage}}[/tex]

[tex]\boxed{\begin{minipage}{4.5 cm}\underline{Differentiating $\ln x$}\\\\If $y=\ln x$, then $\dfrac{\text{d}y}{\text{d}x}=\dfrac{1}{x}$\\\end{minipage}}[/tex]
Differentiate the given function using the chain rule:
[tex]\begin{aligned}f(x) & = \left(\ln x\right)^2\\\implies f'(x)& = 2\left(\ln x\right)^{2-1} \cdot \dfrac{\text{d}}{\text{d}x} \ln x\\& = 2\left(\ln x\right)^{1} \cdot \dfrac{1}{x}\\& = \dfrac{2}{x} \ln x \end{aligned}[/tex]
To find the gradient of the function at x = 2, substitute x = 2 into the differentiated function:
[tex]\implies f'(2) = \dfrac{2}{2} \ln 2 = \ln 2[/tex]
Therefore, the gradient of the function at x = 2 is ln(2).
Substitute x = 2 into the function to find the y-value of the point on the curve when x = 2:
[tex]\implies f(2)= \left( \ln 2\right)^2[/tex]
Slope-intercept form of a linear equation:
[tex]y=mx+b[/tex]
where:
m is the slope.b is the y-intercept.Substitute the point (2, (ln 2)²) and the found gradient into the slope-intercept formula and solve for b:
[tex]\begin{aligned} y & = mx+b\\\implies \left(\ln 2 \right)^2 & = \ln 2 \cdot 2 + b\\\left(\ln 2 \right)^2 & =2\ln 2 +b\\b & = \left(\ln 2 \right)^2-2 \ln 2\end{aligned}[/tex]
Therefore, the tangent has the equation:

Solve each system.
2m = -4n - 4 , 3m + 5n = -3
After solving each system, 2m = -4n - 4, 3m + 5n = -3, the values of m and n are calculated to be 4 and -3 respectively.
The two given equations, 2m = -4n - 4, and 3m + 5n = -3 are considered to be linear equations since the highest power of the variables in these equations is one.
By rearranging the second equation, the value of m is calculated to be,
3m + 5n = -3
3m = -3 - 5n
m = -3 - 5n / 3
Putting the calculated value of m in the first equation,
2m = -4n - 4
2(-3 - 5n / 3) = -4n - 4
-6 - 10n / 3 = -4n - 4
-6 - 10n = 3(-4n - 4)
-6 - 10n = -12n - 12
-10n + 12n = -12 + 6
2n = -6
n = -6/2
n = -3
To solve for m, put n = -3 in the first equation as follows,
2m = -4n - 4
2m = -4(-3) - 4
2m = 12 - 4
m = 8 / 2
m = 4
Thus the value of m and n in these systems are calculated to be 4 and -3 respectively.
