Answer:

Step-by-step explanation:

Let’s define the number of rides that Zeek can ride as “r”.

To determine how many rides Zeek can ride, we need to first subtract the cost of admission from his total budget:

$30 - $13 = $17

This means that Zeek has $17 left to spend on rides. Since each ride costs $2, we can set up the following equation:

$2r = $17

To solve for “r”, we divide both sides of the equation by $2:

r = $8.50

So Zeek can ride a maximum of 8 rides with the $17 he has left after paying for admission. However, since he cannot ride a fraction of a ride, he may be limited to only 8 rides or fewer.

Answer:

The volume of the cylinder is 500 π cubic kilometers.

Step-by-step explanation:

Formula: V = πr²h

r = d/2

r = 20km/2

r = 10 km

h = 5km

Solve for the volume using the formula.

Substitute the given

V = π(10km)²(5km)

V = 500π km³

Given WX is tangent to OS at point V, the statements that must be true include:

A. m∠TVX =m∠TVX

C. m∠TVW = m∠TSV

D. m∠TUV =m∠TVW

In mathematics, a tangent is a line that touches a curve at exactly one point, without intersecting it at that point. The tangent line at a point on a curve represents the slope of the curve at that point. The concept of tangent is important in calculus, where it is used to calculate derivatives of functions.

The assumption of a decay constant of k = 0.1, we estimate that there would be approximately 36.788 fossils per cubic meter after 10 years.

To estimate the number of fossils after 10 years, we need to solve the given equation. However, since the equation is not provided, we'll assume a simple exponential decay model for the population of fossils.

Let's assume the equation for the population of fossils is:

N(t) = N0 * e^(-kt)

where:

N(t) is the number of fossils after t years,

N0 is the initial number of fossils,

k is a decay constant, and

e is the base of the natural logarithm (approximately 2.71828).

Since the initial number of fossils is given as 100, we have N0 = 100. Now, we need to find the value of the decay constant (k) to estimate the number of fossils after 10 years.

Without further information, it's challenging to determine the exact decay constant. However, let's assume a hypothetical value of k = 0.1 for this example.

Plugging the values into the equation, we get:

N(10) = 100 * e^(-0.1 * 10)

= 100 * e^(-1)

≈ 100 * 0.36788

≈ 36.788

So, with the assumption of a decay constant of k = 0.1, we estimate that there would be approximately 36.788 fossils per cubic meter after 10 years.

Answer:

B. 2333.59

Step-by-step explanation:

We have been given the following differential equation:

[tex]\dfrac{dN}{dt}=\dfrac{5000}{6+5t}[/tex]

To find the number of fossils N(t) after t = 10 years, we first need to solve the differential equation using integration and the given parameters to create an equation for N(t) in terms of t.

Solving a differential equation means using it to find an equation in terms of the two variables, without a derivative term.

Rearrange the equation so that all the terms containing N are on the left-hand side, and all the terms containing t are on the right-hand side:

[tex]1\;dN=\dfrac{5000}{6+5t}\; dt[/tex]

Integrate both sides:

[tex]\displaystyle \int 1 \;dN=\int \dfrac{5000}{6+5t}\; dt[/tex]

Use the following integration rules:

[tex]\boxed{\begin{minipage}{8.5 cm}\underline{Integration rulest}\\\\\\$\displaystyle \int n\:\text{d}x=nx+\text{C}$\;\;(where $n$ is any constant value)\\\\\\$\displaystyle \int \dfrac{n}{a+bx}\:\text{d}x=\dfrac{n}{b}\ln |a+bx|+\text{C}$\\\\ \end{minipage}}[/tex]

Therefore:

[tex]\begin{aligned}\displaystyle \int 1\;dN&=\int \dfrac{5000}{6+5t}\; dt\\\\\implies N&=\frac{5000}{5}\ln \left|6+5t\right|+C\\\\N&=1000\ln \left|6+5t\right|+C\end{aligned}[/tex]

As the initial number of fossils is 100, then N = 100 when t = 0.

Substitute these values into the equation and solve for C:

[tex]100=1000\ln \left|6+5(0)\right|+C[/tex]

[tex]C=100-1000\ln (6)[/tex]

Therefore, the equation for N in terms of t is:

[tex]N=1000\ln \left|6+5t\right|+100-1000\ln(6)[/tex]

Use the quotient log rule to simplify:

[tex]N=1000\ln \left|6+5t\right|-1000\ln(6)+100[/tex]

[tex]N=1000\ln \left(\dfrac{\left|6+5t\right|}{6}\right)+100[/tex]

To estimate the number of fossils after 10 years, substitute t = 10 into the equation:

[tex]N=1000\ln \left(\dfrac{\left|6+5(10)\right|}{6}\right)+100[/tex]

[tex]N=1000\ln \left(\dfrac{56}{6}\right)+100[/tex]

[tex]N=2333.59\; \sf (2\;d.p.)[/tex]

Therefore, the number of fossils after 10 years is 2333.59.

After applying factorization of the given functions the evaluated expression comes out to be (2x + 1)(x² - x - 4.8), under the condition the given function is P(x)=2x × 3- 5.6x +1

In order to factorize the given polynomial P(x) = 2x³ - 5.6x + 1, we can apply the Rational Root Theorem. The theorem projects that in an incident when a  polynomial has integer coefficients, then any rational roots must have a numerator that divides the constant term and a denominator that divides the leading coefficient.
For the given case, the leading coefficient is 2 and the constant term is 1.
Hence, any rational roots must be of the form p/q where p divides 1 and q divides 2. This elaborates that the possible rational roots are ±1/2 and ±1.
We can observe these roots applying synthetic division. Using synthetic division with root -1/2 gives us:
-1/2 | 2   0   -5.6   1
    |    -1    0.8  -0.5
    -------------------
          2   -1   -4.8  0.5

The surface area of the given cylinder is approximately 1758.4 square yards.

To find the surface area of a cylinder, we need to calculate the sum of the areas of its curved surface (lateral surface area) and its two circular bases.

Given:

Height (h) = 18 yards

Radius (r) = 10 yards

π (pi) ≈ 3.14

Lateral Surface Area:

The lateral surface area of a cylinder can be calculated using the formula 2πrh, where r is the radius and h is the height.

Lateral Surface Area = 2πrh

Substituting the given values, we have:

Lateral Surface Area = 2 × 3.14 × 10 × 18

Lateral Surface Area = 1130.4 square yards (rounded to the nearest hundredth)

Circular Bases:

The area of a circle can be calculated using the formula πr^2, where r is the radius.

Area of a Circular Base = π[tex]r^2[/tex]

Substituting the given radius, we have:

Area of a Circular Base = 3.14 × [tex]10^2[/tex]

Area of a Circular Base = 314 square yards

To find the total surface area, we need to add the lateral surface area and the areas of the two circular bases.

Total Surface Area = Lateral Surface Area + 2 × Area of a Circular Base

Substituting the values, we get:

Total Surface Area = 1130.4 + 2 × 314

Total Surface Area = 1758.4 square yards (rounded to the nearest hundredth)

Therefore, the surface area of the given cylinder is approximately 1758.4 square yards.

Answer:

31 years

Step-by-step explanation:

A = P(interest rate)^number of years (n)

if the money is to quadruple, A = 4 X 22,000 = 88,000.

P = investment amount = 22,000.

interest rate is 4.5%. so we have the whole (100%) + 4.5% = 1.045%.

n is number of years.

22,000 (1.045)^n = 88, 000

divide both sides by 22, 000:

(1.045)^n = 4

take logs for both sides:

log (1.045)^n = log 4

simplify using log laws (by bringing down the n):

n log (1.045) = log 4

divide both sides by log (1.045):

n = (log 4) / log (1.045)

= 31.49 (31 years to nearest year)
