[tex]$\frac{2}{7}[/tex] fraction of the total distance to her grandmother’s house traveled on Sunday.

Joanie's family traveled [tex]$\frac{2}{7}[/tex] of the distance to her grandmother’s house on Saturday.

They traveled [tex]$\frac{2}{5}[/tex] of the remaining distance on Sunday.

Let us consider the total distance to be 1.

Then subtract the distance traveled on Saturday from the total distance to calculate the remaining distance.

On subtracting we get the remaining distance:

Remaining distance = [tex]$\frac{7}{7} - \frac{2}{7}[/tex]

Remaining distance = [tex]$\frac{5}{7}[/tex]

Here we have to determine the fraction of the total distance to her grandmother’s house traveled on Sunday.

They traveled [tex]$\frac{2}{5}[/tex] of the remaining distance on Sunday.

To calculate the [tex]$\frac{2}{5}[/tex] fraction of the remaining distance we have to multiply both the fractions.

On multiplying we get:

[tex]$=\frac{5}{7} \times \frac{2}{5}[/tex]

[tex]$= \frac{2}{7}[/tex]

Therefore the distance traveled on the Sunday is  [tex]$\frac{2}{7}[/tex] a fraction.

The area of the triangle spanned by the vectors u and v can be calculated by taking the magnitude of the cross product of the two vectors. The cross product of u and v is (6, 4, -8) and the magnitude of this vector is 10, so the area of the triangle is 10.

The area of a triangle spanned by two vectors u and v can be calculated by taking the magnitude of the cross product of the two vectors. To calculate the cross product of two vectors u and v, we use the formula u x v = (u2v3 - u3v2, u3v1 - u1v3, u1v2 - u2v1). For our vectors, u = (1, 2, -2) and v = (0, -1, 3), the cross product is (6, 4, -8). We then calculate the magnitude of the cross product, which can be done using the formula |u x v| = √(u2v3 - u3v2)2 + (u3v1 - u1v3)2 + (u1v2 - u2v1)2. Substituting in the values for our vectors gives |u x v| = √62 + 42 + (-8)2, which is equal to 10. Therefore, the area of the triangle spanned by the vectors u and v is 10.

Answer: 191.8 feet

Step-by-step explanation:

The equation for the ball's height h at time t seconds after launch is h(t) = -16t^2 + 1.6t + 190.4.

To find the maximum height the ball achieves before landing, we need to find the maximum value of h(t). To do this, we need to find the vertex of the parabola represented by the equation. The vertex of a quadratic equation in the form of y = a(x-h)^2 + k is (h, k), where h is the x-coordinate of the vertex and k is the y-coordinate of the vertex.

We can find the x-coordinate of the vertex by using the formula:

h = -b/2a

Here, a = -16, b = 1.6, and c = 190.4

Plugging these values into the formula:

h = -1.6/2*(-16) = 1/8

The x-coordinate of the vertex is 1/8 of a second, which is the time at which the ball reaches its maximum height.

To find the y-coordinate of the vertex, we can plug in the value of t = 1/8 into the equation for h(t):

h(1/8) = -16(1/8)^2 + 1.6(1/8) + 190.4

This gives us the maximum height that the ball achieves before landing, which is approximately 191.8 feet.

830.72 sq in of wrapping paper does Tiana need to buy.

What is surface area of a cylinder?

The formula for the surface area of a cylinder is

SA = 2πr^2 +2πrh = 2πr(r +h)

To find the total area of wrapping paper needed for one box, Tiana needs to add up the area of each of the six sides. The area of the top and bottom is,

22.2 inches * 4.8 inches = 106.56 square inches.

The area of each of the four sides is 14 inches * 22.2 inches = 308.8 square inches.

So, the total area of wrapping paper needed for one box is,

106.56 + 308.8 = 415.36 square inches.

Since, Tiana needs to wrap 2 boxes, she needs to buy twice that amount, which is 2 * 415.36 = 830.72 square inches.

Rounding to the nearest hundredth, Tiana needs to buy 830.72 sq in of wrapping paper.

Hence, 830.72 sq in of wrapping paper does Tiana need to buy.

What is percentage ?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used.

The formula to calculate the future value of an investment is:

FV = PV * (1 + r/n)^(nt)

where:

PV = present value = $1,000

r = annual interest rate = 8.25%

n = number of compounding periods per year = 12 (monthly)

t = number of years = 3

FV = $1,000 * (1 + 0.0825/12)^(12 * 3)

Plugging in the values and using a calculator, we get:

FV = $1,000 * (1 + 0.0825/12)^(12 * 3) = $1,000 * (1.006866)^36 = $1,000 * 1.281216 = $1,281.216

(a)The percentage error is 0.123%.

(b)The percentage error is 0.049%.

Find the equation of the tangent line at the point (0,f(0)),

⇒ f(x)  = exp(x/500)
⇒ f'(x) = 1/500 exp(x/500)

⇒ f(0) = exp(0/500)

          = 1

So the equation of the tangent line at x = 0 is,

⇒ y = f(0) + f'(0)(x - 0) y

      = 1 + 1/500x y

      = x/500 + 1

Find the equation of the tangent line at the point (100,f(100)),

⇒ f(x)  = exp(x/500)

⇒ f'(x) = 1/500 exp(x/500)

⇒ f(100) = exp(100/500)

             = exp(1/5)

So the equation of the tangent line at x = 100 is,

⇒ y = f(100) + f'(100) (x - 100)

⇒ y = e^(1/5) - (1/500)(x - 100)

⇒ y = -x/500 + exp(1/5) + 1

Now we can use these two equations to approximate the function f(x) for 0 < x < 100.

For example, when x = 25

⇒ y = x/500 + 1

⇒ y = 25/500 + 1

⇒ y = 1.05

And the actual value of f(25) is,

⇒ f(25) = exp(25/500)

⇒ f(25) = exp(1/20)

⇒ f(25) ≈ 1.0513

So the percentage error is,

⇒ |1.05 - 1.0513| / 1.0513 x 100% ≈ 0.123%

We can repeat the process for x = 50 and find that the percentage error is 0.049%.
