is square root 35 irrational or rational
Answers
The square root of 35 is an irrational number because it cannot be expressed as a precise fraction or whole number.
Explanation:The square root of 35 is an irrational number. Let me explain why. A number is rational if it can be expressed as a fraction of two integers, in other words, if it can be written in the form a/b where a and b are integers and b ≠ 0. The square root of a perfect square (like 9, 16, 25 and so on) is a rational number because it can be expressed as a whole number. But if a number is not a perfect square (like 35), its square root is generally an irrational number. The square root of 35 cannot be expressed as a whole number or as a precise fraction, hence it is an irrational number.

Answers
y = √x => dy / dx = 1 / (2√x)
(a) Find dy/dt, given x = 16 and dx/dt = 7.
dy/dt = [ 1/(2√x) ] * 7 = [1/(2*4)] * 7 = 7/8
(b) Find dx/dt, given x = 64 and dy/dt = 8.
dx/dt = [dy/dt] / [dy/dx] = 8 / [1/(2√64) ] = 128
(a) The value of [tex]\frac{dy}{dt}[/tex] is [tex]\boxed{\dfrac{dy}{dt}=\dfrac{7}{8}}[/tex].
(b) The value of [tex]\frac{dx}{dt}[/tex] is [tex]\boxed{\dfrac{dx}{dt}=128}[/tex].
Further explanation:
Given that [tex]x[/tex] and [tex]y[/tex] are both differentiable functions of [tex]t[/tex].
The function is as follows:
[tex]\fbox{\begin\\\ \math y=\sqrt{x}\\\end{minispace}}[/tex]
Derivatives of parametric functions:
The relationship between variable [tex]x[/tex] and variable [tex]y[/tex] in the form [tex]y=f(t)[/tex] and [tex]x=g(t)[/tex] is called as parametric form with [tex]t[/tex] as a parameter.
The derivative of the parametric form is given as follows:
[tex]\fbox{\begin\\\ \dfrac{dy}{dt}=\dfrac{dy}{dx}\times\dfrac{dx}{dt}\\\end{minispace}}[/tex]
The above equation is neither explicit nor implicit, therefore a third variable is used.
Part (a):
It is given that [tex]x=16[/tex] and [tex]\frac{dx}{dt}=7[/tex].
To find the value of [tex]\frac{dy}{dt}[/tex] first find the value of [tex]\frac{dy}{dx}[/tex] that is shown below:
[tex]\begin{aligned}y&=\sqrt{x}\\\dfrac{dy}{dx}&=\dfrac{1}{2\sqrt{x}}\end{aligned}[/tex]
The value of [tex]\frac{dy}{dt}[/tex] is calculated as follows:
[tex]\begin{aligned}\dfrac{dy}{dt}&=\dfrac{dy}{dx}\times\dfrac{dx}{dt}\\&=\dfrac{1}{2\sqrt{x}}\dfrac{dx}{dt}\end{aligned}[/tex]
Now, substitute the value of [tex]x[/tex] and [tex]\frac{dx}{dt}[/tex] in above equation as shown below:
[tex]\begin{aligned}\dfrac{dy}{dt}&=\dfrac{1}{2\sqrt{16}}\times7\\&=\dfrac{1}{2\times4}\times7\\&=\dfrac{7}{8}\end{aligned}[/tex]
Therefore, the required value of [tex]\frac{dy}{dt}[/tex] is [tex]\frac{7}{8}[/tex].
Part (b):
It is given that [tex]x=64[/tex] and [tex]\frac{dy}{dt}=8[/tex].
To find the value of [tex]\frac{dx}{dt}[/tex] first find the value of [tex]\frac{dx}{dt}[/tex] that is shown below:
[tex]\begin{aligned}y&=\sqrt{x}\\\dfrac{dy}{dx}&=\dfrac{1}{2\sqrt{x}}\\\dfrac{dx}{dy}&=2\sqrt{x}\end{aligned}[/tex]
The value of [tex]\frac{dx}{dt}[/tex] is calculated as follows:
[tex]\boxed{\dfrac{dx}{dt}=\dfrac{dx}{dy}\times\dfrac{dy}{dt}}[/tex]
Now, substitute the value of [tex]\frac{dx}{dy}[/tex] and [tex]\frac{dy}{dt}[/tex] in above equation as shown below:
[tex]\begin{aligned}\dfrac{dx}{dt}&=2\sqrt{64}\times 8\\&=2\times8\times8\\&=2\times64\\&=128\end{aligned}[/tex]
Therefore, the required value of [tex]\frac{dx}{dt}[/tex] is [tex]128[/tex].

Let y represent the total cost of publishing a book (in dollars). Let x represent the number of copies of the book printed. Suppose that x and x are related by the equation.
What is the change in the total cost for each book printed?
What is the cost to get started (before any books are printed)?
Equation: y=1250+25x
Answers
Part 2: the cost to get started before any books are printed. Using the equation, x = 0. So, y =1250+25(0)
y= 1250
So the cost to get started before any books are printed is 1250.
Now, to part 1, let us say, only 1 book is printed. So x=1
y = 1250 +25(1)
y= 1250 +25
y = 1275
So, for 1 book is 1275, and no book is 1250. This gives us the answer that the change in the total cost for each book printed would be $25. Hope this is the answer that you are looking for.

Brianna went to Los Angeles for a vacation. She spent 5 nights at a hotel and rented a car for 6 days. Justin stayed at the same hotel, but spent 7 nights and rented a car for 8 days from the same company. If Brianna paid $1170 and Justin paid $1610, how much did one night at the hotel cost?
Answers
$150 per night
Use a system of equations using x (cost of hotel) and y (cost of car):
5x + 6y = 1170
7x + 8y = 1610
Solve for y in one of the equations and then use substitution to solve for x in the other:
6y = 1170 - 5x
y = (-5/6)x + 195
7x + 8((-5/6)x + 195) = 1610
7x + (-20/3)x + 1560 = 1610
(1/3)x +1560 = 1610
(1/3)x = 50
x = $150 a night

40 is rounded to the nearest whole write down the maximum possible length it could have been
Answers
The maximum length the number could have been before being rounded down to 40 is just under 40.5 since that is the point at which it would round up to 41.
Explanation:The question pertains to rounding numbers to the nearest whole number. When rounding the number 40 to the nearest whole, we'd like to find the maximum length it could have been before rounding down. The process of rounding will round a number to the nearest whole number based on the decimal value. For instance, if you are rounding to the nearest whole number, a number with a decimal part of 0.5 or higher will round up, while a number with a decimal part of less than 0.5 will round down.
Given that 40 is already a whole number, this implies it could have been rounded down from a number up to one decimal less than 40.5 since any number 40.5 and above would round up to 41. Hence, the maximum possible length it could have been before rounding down is just under 40.5.

The answer is 7 apex
Answer-
The length of PR is 7 units.
Solution-
Given,

m∠D = 25°, m∠E = 114°, DF = 21, DE = 15
in the ΔPQR,
m∠P = 25°, m∠Q = 114°, PR = x, PQ = 5
So, ΔDEF ~ ΔPQR by AA (Angle-Angle) similarity, as
m∠D = m∠P = 25°m∠E =m∠Q = 114°So, according to similarity
[tex]\Rightarrow \dfrac{DF}{PR}=\dfrac{DE}{PQ}=\dfrac{EF}{QR}[/tex]

Answers
Bob's team won 12 out of the 16 games it played, which is calculated by multiplying the total number of games (16) by the percentage of games won (75%).
Bob's team won 75% of its baseball games and played 16 games in all. To find out how many games the team won, we can use the formula:
Number of games won = (Percentage of games won / 100) x Total number of games played
Number of games won = (75 / 100) x 16
Number of games won = 0.75 x 16
Number of games won = 12
So, Bob's team won 12 out of the 16 games played.

Suppose f is continuous on [1,5] and the only solutions of the equation f(X)= 6 are x=1 and x=4. If f(2)=8, explain why f(3)>6. ...?
Answers
Given the conditions of the continuous function f and the equation f(X) = 6 where X = 1 and X = 4, f(3) must be greater than 6 because of the utilization of the Intermediate Value Theorem.
Explanation:The question is about the function f which is continuous on the interval [1,5]. The given conditions are that the solutions of the equation f(X) = 6 are x = 1 and x = 4 and that f(2) = 8 which is greater than 6. By the Intermediate Value Theorem (IVT), since f is continuous on [1,5] and f(2) = 8 > 6 and we have that f(x) = 6 for x = 1 and x = 4, then by the IVT we should have a point f(c) = 6 for some c in the interval (2,4). Hence, it means that f(3) could be equal to 6 or be more than 6, but since we know the only solutions are x = 1 and x = 4, f(3) cannot be equal to 6 and thus f(3) must be greater than 6.

An angle measure is 6 degrees more than 3 times its compliment. find the measure of the angle.
Answers
The angle which is 6 degrees more than 3 times its complement is found to be 69 degrees.
Explanation:This problem is related to complementary angles in Mathematics. Complementary angles are two angles that add up to 90 degrees. If we denote one angle as x, its complement is 90 - x.
According to the question, an angle measure is 6 degrees more than 3 times its complement. So we write an equation from this: x = 3*(90 - x) + 6. By solving this equation, we can find the value of x which represents the angle.
First, distribute through the parenthesis: x = 270 - 3x + 6. Combine like terms: 4x = 276. Finally, divide both sides by 4 to solve for x: x = 69 degrees.
So, the angle is 69 degrees.

The annual rate of change in the federal minimum wage rate from 1991 to 1997 is $0.15 per year.
Explanation:The annual rate of change in the federal minimum wage rate from 1991 to 1997 can be found by calculating the difference between the final and initial values, and then dividing it by the number of years.
Initial value in 1991: $4.25
Final value in 1997: $5.15
Difference: $5.15 - $4.25 = $0.90
Number of years: 1997 - 1991 = 6 years
Annual rate of change: $0.90 / 6 = $0.15
Therefore, the annual rate of change in the federal minimum wage rate from 1991 to 1997 is $0.15 per year.

he says he read 1/3 of his novel. Let x represent number of pages of the novel.
1/3x is one third of that novel.
3 pages less than one third is:
