The given statement states that the parametrization of both the tangent line there at designated position is 7x - 4y = 3.

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.

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

The number of hours lopudres will have to jog is .4 hours.

Lord wants to run at least 1.5 miles, and her pace is shown in the picture as 3.75 miles per hour, and the question asks us to construct an inequality expressing x for the amount of hours she would have to run. To meet this inequality, we'll need to apply how quickly or how many miles she wants to cover with how fast she's going to run, so we'll divide 1.5 miles by her rate of 3.75 miles per hour, and when you divide you'll get a number of hours, which comes out to 0.4 hours.

The function that represents the total amount he charges is y = 80 + 65x and the total amount he charges for designing 5 rooms is $405

The given parameters are

Charge = $80

Rate = $65 per design

The function is then calculated as

y = Charge + Rate * x

Where

y represents the total amount

x represents the number of rooms

So, we have

y = 80 + 65x

Here, we have

x = 5

So, we have

y = 80 + 65 x 5

Evaluate

y = 405

Hence, the total amount he charges for designing 5 rooms is $405

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

To find

So according the question

We have

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

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

Fractions are one of the most important aspects of arithmetic that we use in our daily lives. Fractions are denoted by the symbol / (also known as the fractional line) and represent a numerical value that is a portion of the total value, for example, a/b. Formulas for fractions aid in the development of rules for performing the four basic arithmetic operations of addition, subtraction, multiplication, and division.

Given data:

Cheese used for making 2 [tex]\frac{3}{4}[/tex] pizza = 2 [tex]\frac{1}{2}[/tex]

Cheese used for making 1 pizza = 2 [tex]\frac{1}{2}[/tex] ÷ 2 [tex]\frac{3}{4}[/tex]

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.

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.

There are 1106 different ways for him to choose the meal.

For given question,

In a restaurant there are 7 starter dishes, 14 main dishes and 9 desserts.

The possibilities of selecting a starter = 7

The possibilities of selecting a main dish = 14

The possibilities of  selecting a dessert = 9

The meal combinations are: a starter dish and a main dish; a main dish and dessert; a starter dish, main dish and dessert dish.

The possibility of selecting each meal combinations would be,

1) a starter dish and a main dish = 7 × 14

                                                     = 98  

2) a main dish and dessert = 14 × 9

3) a starter dish, main dish and dessert dish

   = 7 × 9 × 14
