The interest earned increases with higher principal amounts, higher interest rates, and longer time periods.

Principal (P) | Interest Rate (r) | Time Period (t) | Interest Earned (I)

$1,000 | 2% | 1 year | $20

$5,000 | 4% | 2 years | $400

$10,000 | 3.5% | 3 years | $1,050

$2,500 | 1.5% | 6 months | $18.75

$7,000 | 2.25% | 1.5 years | $236.25

To calculate the interest earned (I), we can use the simple interest formula: I = P * r * t.

For the first row, with a principal of $1,000, an interest rate of 2%, and a time period of 1 year, the interest earned is calculated as follows: I = $1,000 * 0.02 * 1 = $20.

For the second row, with a principal of $5,000, an interest rate of 4%, and a time period of 2 years, the interest earned is calculated as follows: I = $5,000 * 0.04 * 2 = $400.

For the third row, with a principal of $10,000, an interest rate of 3.5%, and a time period of 3 years, the interest earned is calculated as follows: I = $10,000 * 0.035 * 3 = $1,050.

For the fourth row, with a principal of $2,500, an interest rate of 1.5%, and a time period of 6 months (0.5 years), the interest earned is calculated as follows: I = $2,500 * 0.015 * 0.5 = $18.75.

For the fifth row, with a principal of $7,000, an interest rate of 2.25%, and a time period of 1.5 years, the interest earned is calculated as follows: I = $7,000 * 0.0225 * 1.5 = $236.25.

These calculations show the interest earned for different savings principals, interest rates, and time periods.

Nearly 1,659 feet of granite was tunnelled through to make tunnel no. 6 through the sierra Nevada mountains.

Early snowfall prevented the Central Pacific from starting construction on Tunnel No. 6, or the Summit Tunnel, in August 1865. It was built using a variety of engineering and construction methods and was located more than seven thousand feet above sea level.

When the workmen finally broke through, they discovered that they were only two inches off from the calculations that were used to locate its end points and central shaft. The length of the tunnel that was built through the Sierra Nevada mountains is therefore given as nearly 1,659 feet of granite was tunnelled through to make tunnel no. 6 through the Sierra Nevada mountains.

Therefore , the solution of the given problem of equation comes out to be  y = 23.78t - 5t²

An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.

Here,
Given :parametric equation

x be the speed of water

t be the time

v be the speed of dolphin

=> x = (vcosx)t +x₀

=> v = 32

=> x = 48

=> x = (32 X cos 48)t + 0

=> x = 21.41t

thus,

=>  y = (vsintx)t - 1/2gt² + y₀

=>   y₀ = 0

=>  v = 32

=> x = 48

=> g = 10

=> y = (32sin48)t -1/2 *10*t² +0

=>  y = 23.78t - 5t²

Answer:

Perimeter of rectangle = 6√10 units (the attachment isnt clear. It seems the answer is in option B)

Step-by-step explanation:

First we find the distance of the length and width of the rectangle.

Distance between E and F = Distance EF

Distance EF = √(∆y²-∆x²)

= √[(5-7)² + (1-7)²] = √[(-2)² + (-6)²]

= √(4+36) = √40

Distance EF = 2√10

Distance between F and G = Distance FG

Distance FG = √(∆y²-∆x²)

= √[(2-5)² + (2-1)²] = √[(-3)² + (1)²]

= √(9+1) = √10

Distance FG = √10

Length= distance EF = distance HG

And width = distance FG = distance EH

Perimeter of rectangle = 2(length + width)

Perimeter of rectangle = 2(2√10 + √10)

= 2(3√10)

Perimeter of rectangle = 6√10 units (the attachment isnt clear. It seems the answer is in option B)

We are asked to find the proportion of sugar to number of cookies

Sugar = 200g

Number of cookies = 48

proportion of sugar to cookies = 200 : 48

how many cookies he can make with 350 grams of sugar?

let x = number of cookies

proportion of sugar to cookies = 350 : x

equate the proportions

200 : 48 = 350 : x

200/48 = 350/x

cross product

200 × x = 350 × 48

200x = 16800

x = 16800/200

x = 84 cookies

find the number of cookies, y, Ezra can make with x grams of sugar?

y = grams of sugar, x / number of cookies

y = 350/84

y = 4.17x

Using vector calculus:

∇f = \((4z^2, -5xz, -7xy^3)\)

∇×f = \((-35xy^2, 0, 4z)\)

f × ∇f = \((-5x^2y^2z^2, 28x^3y^5z^2, 16x^4y^4z)\)

f ⋅ ∇f = \(16x z^4 - 25x^2y^2z^2 + 49x^2y^6z\)

To find the gradient, curl, cross product, and dot product of the given vector field and scalar field, we can use the standard formulas for vector calculus:

For the vector field f(x,y,z) = (\(4xz^2, -5xyz, -7xy^3z\)), we have:

∇f = (∂f/∂x, ∂f/∂y, ∂f/∂z)

= (\(4z^2, -5xz, -7xy^3\))

To find the curl of f, we compute the determinant of the following matrix:

| i j k |

| ∂/∂x ∂/∂y ∂/∂z |

| \(4xz^2 -5xyz -7xy^3z\) |

This gives:

∇×f = (∂(\(-7xy^3z\))/∂y − ∂(−5xyz)/∂z, ∂(\(4xz^2\))/∂z − ∂(\(-7xy^3z\))/∂x, ∂(−5xyz)/∂x − ∂(\(4xz^2\))/∂y)

= (\(-35xy^2, 0, 4z\))

To find the cross product of f and ∇f, we have:

f × ∇f = det | i j k |

| \(4xz^2 -5xyz -7xy^3z\) |

| \(x^3y^2z x^2y^2 x^3y^2\) |

= (\(-5x^2y^2z^2, 28x^3y^5z^2, 20x^4y^4z - 4x^4y^4z\))

= (\(-5x^2y^2z^2, 28x^3y^5z^2, 16x^4y^4z\))

Finally, to find the dot product of f and ∇f, we have:

f ⋅ ∇f = \(4xz^2 * 4z^2 - 5xyz * 5xz - 7xy^3z * (-7xy^3)\)

= \(16x z^4 - 25x^2y^2z^2 + 49x^2y^6z\)

y= 3i +2k

Generally the equation for Matrix of the Parallelogram is mathematically given by

 \(x*y=\)\(\begin{vmatrix}i & j & k\\1 & 1 & 1\\3 & 0 & 2 \end{vmatrix}\)

 \(x*y=i(2-0)-j(2-3)+k(0-3)\)

Generally the magnitude of x*y is mathematically given as

 \(|u*v|=\sqrt{2^2+1^2+(-3)^2}\)

 \(|u*v|=\sqrt{14}\)

Therefore, the circumference of the circle is 24π feet.

Circumference is the distance around the edge of a circular object. It is the measurement of the perimeter of a circle. To find the circumference of a circle, you can use the formula C = 2πr, where C is the circumference, π is the mathematical constant pi (approximately equal to 3.14), and r is the radius of the circle (the distance from the center of the circle to any point on its edge).

The formula for the circumference of a circle is:

C = 2πr

Where C is the circumference, π is pi, and r is the radius.

Substituting the given value of radius into the formula, we get:

C = 2π(12) = 24π

Therefore, the circumference of the circle is 24π feet.
