Find a parametrization of the tangent line at the point indicated. r(t) = cos(6t), sin(3t) , t = 4
The given statement states that the parametrization of both the tangent line there at designated position is 7x - 4y = 3.
What is parametrization?Finding parametric equations of a curve, a surface, or, more generally, a manifold or a variety, specified by an implicit equation, is the process of parametrization (or parameterization; see parameterization, parametrization). Implicitization is the term for the opposite process. The parametrization consists of one function of multiple real variables for each coordinate since the state of the system is typically controlled by a finite set of coordinates. The system's degree of freedom is equal to the number of parameters.
According to the given data:r(t) = cos(6t), sin(3t) , t = 4
= -6sin6t, 3cosjt , 1
The parameter of Tangent live is
L(t) = γ(t₀) + tr'(t₀)
therefore
γ(t₀) = γ(ππ₄)
= (0 , 1/√2 , π/4)γ (+0) = γ(π/4)
= ( 6, -3/√2 , 1)
putting in the formula we get:
L(t) = γ(t₀) + tr'(t₀)
L(t) = (0 , 1/√2 , π/4) + t( 6, -3/√2 , 1)
= [tex]\left(6 t-\frac{1}{\sqrt{2}}-\frac{3}{\sqrt{2}} t, \frac{\pi}{4}+t\right)$$[/tex]
= 2.
Given
f(x, y ) = in(7x² - 4y²)
at the point(1, 1)
Δ f (m, y) = (fn , f4)
= [tex]\frac{14 x}{7 n^2-4 y^2}, \frac{-8 y}{7 x^2-4 y^2}\\\\[/tex]
Δ f (1, 1)
= [tex]\left\langle\frac{14}{3}, \frac{-8}{3}\right\rangle[/tex]
= (a ,b)
The equation of the tangent plane is
a(x - x₀) + 6dy - y₀ = 0
(14/3)(x - 1)- (8/3)(y -1 ) = 0
14x - 14 - 8y + 8 = 0
14x - 8y = 6
7x - 4y = 3

if x is a positive integer, for how many different values of x is startroot startfraction 48 over x endfraction endroot a whole number?236
There are 3 whole number with different values of x.
What is a whole number?
All positive integers from 0 to infinity are included in the group of numbers known as whole numbers. The number line has these numbers. They are all genuine numbers as a result. Although not all real numbers are whole numbers, we may argue that all whole numbers are real numbers. As a result, the set of natural numbers plus zero may be used to define whole numbers. The category of whole numbers and the negative of natural numbers is known as integers. Thus, integers can be either positive or negative, including 0. Natural numbers, whole numbers, integers, and fractions all fall under the category of real numbers.
Whole numbers refer to all natural numbers, including '0,' in their entirety. Examples include: 0, 11,1,2,3,4 etc
As stated in the question,
Accordingly, "x" is a positive integer. In order for the value of [tex]\sqrt{\frac{48}{x} }[/tex]to be a whole number, we must determine how many alternative values there are for the variable "x".Then, in order to determine which values of "x" the given fraction is a square for, we must first locate them.
We are aware that the factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48.
Now, from the above factors of 48 only (3,12 & 48) of can give us a square number.
Therefore,
If x is 3 then [tex]\sqrt{\frac{48}{3} }[/tex]=[tex]\sqrt{16}[/tex]=4If x is 12 then[tex]\sqrt{\frac{48}{12} }[/tex]=[tex]\sqrt{4}[/tex]=2If x is 48 then[tex]\sqrt{\frac{48}{48} }[/tex]=[tex]\sqrt{1}[/tex]=1Hence, There are 3 whole number with different values of x.

A gallon of gasoline costs $2.96. Your car has a 25-gallon gas tank and can travel 28.8 miles on each gallon of gasoline.
a. Find the cost of filling your gas tank if it is already 38 38 full.
b. You take a trip of length 705 miles. How much money do you spend on gasoline?
The cost of filling your gas tank if it is already 38 38 full. $48.88 required to fill the gas tank if it is already 38% full.
Money do you spend on gasoline is $72.46 is spends on that trip.
Given that
A gallon of gasoline costs $2.96.Gas tank capacity of the given car = 25 gallonThat car can travelled 28.8 miles on each gallon of gasoline.To find
The cost of filling your gas tank if it is already 38 % full.How much money spend on gasoline on the trip of 705 miles.So according the question
We have
1 gallon of gasoline = $2.96.Gas tank capacity = 25 gallon.28.8 miles travelled on each gallon of gasoline.Now, for finding
a.) The cost of filling your gas tank if it is already 38 % full.
38 % of 25 gallon = 9.5 gallon
the unfilled part of the tank = 25-9.5 = 15.5 gallon
So the tank can filled 15.5 gallon of gasoline more now.
The cost of 15.5 gallon of gasoline
= 15.5 × cost of 1 gallon of gasoline
= 15.5 × 2.96
= $45.88
$48.88 required to fill the gas tank if it is already 38% full.b.) How much money spend on gasoline on the trip of 705 miles.
∵ Car can travelled in 1 gallon of gasoline = 28.8 miles.
∴ Gasoline required to travel 705 miles = [tex]\frac{705}{28.8}[/tex]
= 24.48 gallon.
The cost of 24.48 gallon of gasoline
= 24.48 × cost of 1 gallon of gasoline
= 24.48 × 2.96

Which equation is true if b = 2?
2b + 24 = 30
3b - 2 = 4
B + 4 = 8
2b - 3 = 0
Answer:
2nd equation is correct.
Step-by-step explanation:
1) 2b + 24 = 30
→ 2(2) + 24 = 30
→ 4 + 24 = 30
→ 28 ≠ 30
Hence, it is false.
2) 3b - 2 = 4
→ 3(2) - 2 = 4
→ 6 - 2 = 4
→ 4 = 4
Hence, it is true.
3) B + 4 = 8
→ 2 + 4 = 8
→ 6 ≠ 8
Hence, it is false.
4) 2b - 3 = 0
→ 2(2) - 3 = 0
→ 4 - 3 = 0
→ 1 ≠ 0
Hence, it is false.
A large grain silo is to be constructed in the shape of a circular cylinder with a hemisphere attached to the top. The diameter of the silo is to be 30 feet, but the height is yet to be determined. Find the height h of the silo that will result in a volume of 11,475(3.14) ft cubed
The height of the silo is 56 feet.
Here, we are given that a large grain silo is to be constructed in the shape of a circular cylinder.
The diameter of the silo = 30 feet
⇒ The radius of the cylinder = 15 feet
and also the radius of the hemisphere = 15 feet
The volume of a hemisphere = 2πr^3/3
Volume = 2 × π × 15 × 15 × 15 × 1/3
Volume of cube = 2250π
Thus, the volume of cylinder = volume of the silo - volume of the hemisphere
= 11,475(3.14) - 2250π
π = 3.14
⇒ 11,475(3.14) - 2250(3.14)
3.14 (11,475 - 2250)
= 3.14 (9225)
= 9225π
Now, the volume of cylinder = πr^2h
Thus, 9225π = π(15) (15) h
9225π/ 225π = h
h = 9225/225
h = 41
Thus, the height of the cylinder = 41
The height of the silo will be the height of hemisphere + height of the cylinder = 15 + 41 = 56 feet.

Please help me find the rule of this linear function:
x-intercept: (-3.667,0)
y-intercept: (0,5.5)
Step-by-step explanation:
what do you mean by "rule" ?
the line equation (in slope-intercept form ? or any other ?) ?
or only the slope of the line ?
I assume you need the slope-intercept line equation.
this looks like
y = ax + b
"a" is the slope of the line, "b" is the y-intercept (the y value when x = 0).
"b" we know already from the specified intercept points : 5.5
the slope of a line is simply the ratio
(y coordinate change / x coordinate change)
when going from one point on the line to another.
and the axis-intercept points are points on the line too. so, we can use them.
so, we see
x changes by +3.667
(= 3 2/3 = 3×3/3 + 2/3 = (3×3 + 2)/3 = 11/3)
from -3.667 to 0.
y changes by +5.5
(= 5 1/2 = 5×2/2 + 1/2 = (5×2 + 1)/2 = 11/2)
from 0 to 5.5
the slope is therefore
5.5 / 3.667 = 11/2 / 11/3 = 11/2 × 3/11 = 3×11 / 2×11 = 3/2
and so, the line equation is
y = 3/2 x + 5.5
or
y = 3/2 x + 11/2 = 1/2 × (3x + 11)
by what factor would you need to change the radius of a sphere, such that its volume increased by a factor of 7? give your answer to two digits.
The factor by which radius of the sphere be changed is 1.91, which is calculated hy applying the concepts of surface area and volume on the assigned problem.
What do you mean by volume?
Volume is defined as the 3D measurement that deals with the amount of space required by an object. It is always calculated in cubic units. Its basic unit is cubic metre.
Calculation of the change in radius of sphere when its volume is increased by 7
Let the radius and volume of sphere be r and v respectively
Volume of sphere, v = 3.16 × ( r )3 —- 1
Now, changed radius, R = xr
Where x is the factor, we need to calculate
Changed volume, V = 7v = 3.16 × ( R )3 -— 2
From equations 1 and 2, we get,
7v / v = ( R )3 / ( r )3
7 = ( xr )3 / ( r )3
7 = (x)3 × 1
Taking cube root both sides,
x = 1.913
Hence, the factor by which radius of the sphere be changed is 1.91.
