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

                                   = $72.46

The simplification of the equation - 2 = 2 + v/4 is v = - 16.

Equation, which is defined as the quality of being equal, is frequently represented by a mathematical expression with equal values on either side or by a situation in which numerous factors must be taken into account.

Consider the equation,

-2 = 2 + v/4

The equation can be rewritten as:

-2 = 2/1 + v/4

The least common multiple or LCM of 1 and 4 is 4.

-2 = ( 2 × 4) / (1 × 4) + v /4

-2 = 8/4 + v/4

-2 = ( 8 + v) /4

Multiplying each side of the equation by 4

- 2 × 4 = [ ( 8 + v ) / 4 ] × 4

- 8 = 8 + v

Subtracting each side of the equation by 8.

- 8 - 8 = 8 + v - 8

v = - 16

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 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 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.

The weight of the egg is 15.79 grams.

Normal Distribution:

Normal distribution, refers the probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Given,

The normal model n(58,21) describes the distribution of weights of chicken eggs in grams.

suppose that the weight of a randomly selected chicken egg has a z-score of -2.01.

Here we need to find the weight of the egg and we have to round off it to the nearest hundredth of gram.

Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:

So,

X ~ n(58, 21)

Where this means the value of

σ =  21

[tex]\mu[/tex] = 58

Apply the values on the formula,

[tex]Z=\frac{x-\mu}{\sigma}[/tex]

=> -2.01 = (x - 58) / 21

=> -2.01 x 21 = x - 58

=> -42.21 + 58 = x

=> x = 15.79

So, the weight of the egg is 15.79 grams.

When we round off it to the nearest hundredth then we get,

=> 15.79

Because there is no hundredth term in this one.
