ST=4x-4 TU=4x-10 and SU =5x+1 determine the numerical length of TU
The numerical length of TU is TU = 26.
What is the numerical length?
The formula states that the base-numerical length of a number is the number of digits in the base-numeral for where is the floor function. An -digit's length is another name for its multiplicative persistence.
Given:
ST=4x-4, TU=4x-10, and SU =5x+1
We have to find the numerical length of TU.
Here,
SU = ST + TU
5x + 1 = 4x - 4 + 4x - 10
Simplifying,
5x + 1 = 8x - 14
Subtract 1 on both sides,
5x + 1 - 1 = 8x - 14 - 1
5x = 8x - 15
Subtract 5x on both sides,
5x - 5x = 8x - 15 - 5x
0 = 3x - 15
3x = 15
x = 5
⇒ TU = 5(5) + 1 = 25 + 1 = 26
Hence, the numerical length of TU is TU = 26.

The y-coordinate rises as the x-coordinate rises when a line's slope is positive, indicating that the line "slopes upward."
How do you know if slope is upward or downward?You may quickly determine whether the graph of a quadratic function expands upward or downward by looking at the leading coefficient: if it is larger than zero, the parabola opens upward; if it is less than zero, the parabola opens downward.
An upward-sloping line has a positive slope when the y-coordinate rises while the x-coordinate falls. In the case of a line with a negative slope, the y-coordinate falls as the x-coordinate rises, causing the line to "slide downward.
With a positive slope, two variables are positively correlated, meaning that as x rises, y rises as well, and as x falls, y falls as well. A line on a line graph with a positive slope goes from left to right while maintaining its visual slope.

Suppose that the number of hours that it takes for a student to finish an inquiry has density
f(x) =
{ 2/5(x + 1) if 1 < x < 2
{ 0 otherwise.
a) Find the probability that the student finishes the inquiry in less than 1.5 hours.
b) Find the mean and standard deviation of the number of hours it takes to finish the inquiry.
The probability that the student finishes the inquiry in less than 1.5 hours is 0.45.
Mean= 4/3 and standard deviation= √(11/90)
a) To find the probability that the student finishes the inquiry in less than 1.5 hours, we need to find the area under the probability density function (PDF) of f(x) between the lower limit of 1 and the upper limit of 1.5.
This is given by the definite integral of f(x) from 1 to 1.5:
∫f(x)dx from 1 to 1.5
= ∫(2/5(x + 1))dx from 1 to 1.5
= (2/5)∫(x + 1)dx from 1 to 1.5
= (2/5)[x^2/2 + x] from 1 to 1.5
= (2/5)[(1.5)^2/2 + 1.5 - (1)^2/2 - 1]
= (2/5)[2.25/2 + 1.5 - 1/2 - 1]
=(2/5)[2.25/2]
=0.45
b) To find the mean, we need to use the formula:
Mean = ∫x*f(x)dx from a to b
In this case:
Mean = ∫x*(2/5(x + 1))dx from 1 to 2
= (2/5)∫x(x + 1)dx from 1 to 2
= (2/5)[x^3/3 + x^2/2] from 1 to 2
=(2/5)[(2)^3/3 + (2)^2/2 - (1)^3/3 - (1)^2/2]
= (2/5)[8/3 + 4/2 - 1/3 - 1/2]
=(2/5)[7/3 + 3/2]
=(2/5)[(20)/6]
=4/3
=1.333
To find the standard deviation, we need to use the formula:
Standard deviation^2 =(∫(x-μ)^2*f(x)dx) from a to b
Where μ is the mean
In this case,
Standard Deviation ^2= ∫(x-μ)^2(2/5)(x+1) dx from 1 to 2
=(2/5)∫(x-μ)^2(x+1) dx from 1 to 2
Simplifying, we get,
(x-μ)^3*(3x+μ+4)/30 from 1 to 2
=[(2-μ)^3*(6+μ+4)-(1-μ)^3*(3+μ+4)]/30
=[(2-μ)^3*(10+μ)-(1-μ)^3*(7+μ)]/30
Substituting the value of μ,
=[(2-4/3)^3*(10+4/3)-(1-4/3)^3*(7+4/3)]/30
=11/90
Therefore, Standard Deviation= √(11/90)

The critical F value with 8 numerator degrees of freedom (also known as the numerator degrees of freedom or the numerator df) and 29 denominator degrees of freedom (also known as the denominator degrees of freedom or the denominator df) at a significance level of 0.01 can be found using a table of F-distribution values or by using a calculator or a software that can compute the F-distribution function.
The critical F value with 8 numerator degrees of freedom (df1) and 29 denominator degrees of freedom (df2) at a significance level of 0.01 can be found using the following formula:
F_critical = F(1 - alpha, df1, df2)

Rashad had ducks and cows on his farm. These 14 animals had a total of 40 legs. How many cows and ducks were there?
The solution to the system of equations is
The number of ducks D = 8 ducks
The number of cows C = 6 cows
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of ducks be D
Let the number of cows be C
Now , the total number of animals = 14
So , D + C = 14 be equation (1)
And , the total number of legs = 40
Number of legs for ducks = 2 legs
Number of legs for cows = 4 legs
And , the total number of legs = 2D + 4C = 40
So , 2D + 4C = 40 be equation (2)
On simplifying the equations , we get
Multiply equation (1) by 2 , we get
2D + 2C = 28 be equation (3)
Subtracting equation (3) from equation (2) , we get
2C = 40 - 28
2C = 12
Divide by 12 on both sides of the equation , we get
C = 6 cows
Substituting the value of C in equation (1) , we get
D = 14 - 6
D = 8 ducks
Therefore , the value of C and D is 6 and 8 respectively
Hence , the number of cows is 6 and number of ducks is 8

Solve 6x - 7y= 18 for y
To solve the equation 6x - 7y = 18 for y, you can start by isolating y on one side of the equation. To do this, you can add 7y to both sides of the equation:
6x - 7y + 7y = 18 + 7y
6x = 18 + 7y
Next, divide both sides of the equation by 7:
6x/7 = 18/7 + 7y/7
x = 3 + y
So the solution is y = 3 - x
This is the final solution for y in the equation 6x - 7y = 18
NO LINKS!! Part 1
Find an exponential function in y = ab^x form that satisfies the given information :
a. Has y-int (0, 2) and has a multiplier of 0.8
b. passes through the points (0, 3.5) and (2, 31.5)
Answer:
A) y = 2*0.8ˣB) y = 3.5*3ˣ-----------------------------------------
Part AUse the coordinates to determine the function.
Point (0, 2):
2 = a*b⁰ ⇒ 2 = aThe function becomes:
y = 2bˣIt has a multiplier of 0.8, so b = 0.8, so the function is:
y = 2*0.8ˣPart BUse the first point:
3.5 = a*b⁰ ⇒ 3.5 = aUse the second point:
31.5 = 3.5*b²9 = b²b = √9b = 3The function is:
y = 3.5*3ˣAnswer:
[tex]\textsf{a)} \quad y=2(0.8)^x[/tex]
[tex]\text{b)} \quad y=3.5(3)^x[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]
Question (a)Given:
y-intercept = (0, 2) ⇒ a = 2multiplier = 0.8 ⇒ b = 0.8Substitute the values of a and b into the exponential function formula:
[tex]\implies y=2(0.8)^x[/tex]
Question (b)The y-intercept is when x = 0. Therefore, given the function passes through point (0, 3.5), the y-intercept is 0.35 ⇒ a = 3.5.
Substitute the found value of a and given point (2, 31.5) into the exponential function formula and solve for b:
[tex]\implies 31.5=3.5b^2[/tex]
[tex]\implies b^2=9[/tex]
[tex]\implies b=3[/tex]
Substitute the values of a and b into the exponential function formula:
[tex]\implies y=3.5(3)^x[/tex]
For what value of n is the following equation true ?
3n = $36.90
Write 24 fluid ounces as a number of cups
24 fl oz = _____ c
1) The equation is true for n = $12.30
2) 24 fluid ounces is equivalent to 3 cups.
For what value of n is the given equation true?Here we want to see for which values of n is the equation:
3n = $36.90
true.
To get that,we need to isolate the variable n. To do so, we can divide both sides by 3.
n = $36.90/3
n = $12.30
That is the value of n.
How to change units?
We want to write 24 fluid ounces as cups, we know the relation:
1 fluid ounce = 0.125cups.
Then we can just do the change of units as follows:
24 fluid ounces = 24*(0.125 cups.) = 3 cups.
So there are 3 cups on 24 fluid ounces.
