Answer:

the answer is 1/12 square foot

Step-by-step explanation:

.

The slope of the tangent line at (0, 5) is 6. The equation of the tangent line is y = 6x + 5.

To find the equation of the line tangent to the graph of y = 6x + 4 at the point (0, 5), we need to find the slope of the tangent line at that point.

The slope of the tangent line is equal to the derivative of the function at the point (0, 5). Taking the derivative of y = 6x + 4 gives us:

dy/dx = 6

Therefore, the slope of the tangent line at the point (0, 5) is 6.

Using the point-slope form of the equation of a line, we can find the equation of the tangent line:

y - 5 = 6(x - 0)

Simplifying, we get:

y = 6x + 5

So the answer is B) y = 6x + 5.

Answer:

a₅ = 80 , \(a_{n}\) = 5\((2)^{n-1}\)

Step-by-step explanation:

to find a term in the geometric sequence multiply the previous term by r

a₁ = 5

a₂ = a₁ × 2 = 5 × 2 = 10

a₃ = a₂ × 2 = 10 × 2 = 20

a₄ = a₃ × 2 = 20 × 2 = 40

a₅ = a₄ × 2 = 40 × 2 = 80

the nth term of a geometric sequence is

\(a_{n}\) = a₁ \((r)^{n-1}\)

here a₁ = 5 and r = 2 , then

\(a_{n}\) = 5 \((2)^{n-1}\)

The implied population in the information provided is (e) the nitrogen concentration (mg nitrogen/1 liter of water) in the entire lake.

The information states that government agencies are monitoring water quality and its effect on wetlands, specifically focusing on the concentration of nitrogen in water draining from fertilized lands. To study this, twenty-eight samples of water were taken at random from a lake, and the nitrogen concentration was determined for each sample.

The purpose of taking these samples and analyzing the nitrogen concentration is to make inferences about the overall nitrogen concentration in the entire lake. The goal is to assess the impact of nitrogen on fish and wildlife in the lake. Therefore, the implied population in this case is the nitrogen concentration in the entire lake, which is the target of the monitoring efforts.

The probability that marksman will hits the target at most 13 times is  27.92%.

The number of successes ("x") is the probability mass function for such binomial distribution.

P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ

We are interested in the likelihood that the target will be struck exactly five times, therefore the desired number of successes is five (i.e., x = 13).

P(X = 13) =  ¹⁵C₁₃. (0.89)¹³ (0.11)²

P(X = 13) = 0.2792

P(X = 13) = 27.92%

Thus, the probability that marksman will hits the target at most 13 times is  27.92%.

Answer:

π 36 m^2

Step-by-step explanation:

C = 2π R = 12π m --> R = 6m

A = π R^2 = π 36 m^2

Answer:

Step-by-step explanation:

In the question we are given that circumference of circle is 12π m . And we are asked to find the area of circle in term of π .

Solution : -

For finding area of circle we need to find the radius of circle . In the question circumference of circle is given . So we can find radius of circle using it . We know that ,

\( \qquad \quad \pink{\underline{\pink{\boxed{\frak{Circumference_ {(Circle) }= 2\pi r}}}}}\)

Where ,

But as in the question , it is given that we have to find the area in term of π. So we aren't using π as 3.14 or 22/7 .

Now, Radius :

\( \longrightarrow \qquad \: 12 \cancel{\pi }= 2 \cancel{\pi} r\)

Step 1 : Cancelling π and we get :

\( \longrightarrow \qquad \:12 = 2r\)

Step 2 : Dividing both sides by 2 :

\( \longrightarrow \qquad \: \cancel{\dfrac{12}{2} } = \dfrac{ \cancel{2}r}{ \cancel2} \)

On further calculations we get :

\( \longrightarrow \qquad \: \boxed{ \bf{r = 6 \: m}}\)

Finding Area :

As we have find the radius of circle above so we can find its area easily . We know that ,

\( \qquad \: \qquad \pink{\underline{\pink{ \boxed{{\frak{ Area_{(Circle)} = \: \pi r {}^{2} }}}}}}\)

Now substituting value of radius :

\( \longmapsto \: \qquad \quad\pi (6) {}^{2} \)

\( \longmapsto \: \qquad \quad \pi \times \: 6 \times 6\)

\( \longmapsto \: \qquad \quad \pi \times 36\)

We get :

\( \longmapsto \: \qquad \quad \blue{\underline{\blue{\boxed{\frak{ \bf{36 \pi \: m {}^{2} }}}}}}\)

Missing part of question:

A pole-vaulter’s approach velocity v (in feet per second) and height reached h (in feet) are related by the following equation.

v=8√h

Answer:

Erwin

Step-by-step explanation:

The equation is

v=8√h

If velocity is 40 feet per second,

40=8√h

√h=40/8

h=√5

height =2.2360ft

If velocity = 35 feet per second,

v=8√h

35=8√h

√h=35/8

√h= 4.375

height =2.09ft

Therefore Erwin reached greater height =2.2360ft

Answer:

0.75 cents

Step-by-step explanation:

quarter is 25 cents and nickels are 5 cents so add 25+25+25=75

Therefore, the correct answer is D. Upon inspection, we can see that sample A does not meet the condition for the chi-square test of independence. In the "D" column, both the curfew yes (1) and curfew no (1) expected cell counts are below 5. Thus, the conditions are not met for sample A to reliably perform the test.

To determine which sample does NOT meet the conditions to reliably perform a chi-square test of independence, we need to check for the assumption that at least 80% of the expected cell counts should be 5 or greater.

Let's analyze the samples:

At the 0.01 significance level, reject the null hypothesis and conclude that women save more than men. we can conclude that there is not enough evidence to support the claim that women save more money than men.

The null hypothesis in this study is that there is no difference in the amount of money saved monthly by single men and women. The alternative hypothesis is that there is a difference in the amount of money saved monthly between single men and women.

To test this hypothesis, we can use a two-sample t-test with equal variances assuming that the population standard deviations are unknown but equal. Using the given data, the t-statistic is calculated to be 1.74.

At the 0.01 significance level with 53 degrees of freedom, the critical value is 2.680. Since the calculated t-statistic of 1.74 is less than the critical value of 2.680, we fail to reject the null hypothesis.

Therefore, we can conclude that there is not enough evidence to support the claim that women save more money than men. At the 0.01 significance level, reject the null hypothesis and conclude that women save more than men.

A tip of 18% was given to the restaurant after the meal and tax to the nearest percentage.

Cost of the food = $25.30

Tax on the food cost = 8%

Tax amount

= 8% of 25.30

= 0.08  × 25.30

= 2.204

Total cost of food before tip = 25.30 + 2.204 = $27.504

Tip given = 32.24 - 27.504 = 5.036

Tip percentage

= 5.036 / 27.504 × 100%

= 18.31%

≈ 18%

Hence a tip of 18% was given to the restaurant after the meal and tax to the nearest percentage.

Percentage increases and decreases are calculated by computing the difference between two numbers or by comparing that difference to the starting value.

The change in the water level per hour for Belvedere's swimming pool is 91.84 gallons per hour. This is rounded to the nearest hundredth.

To find the change in the water level per hour, we need to divide the total number of gallons of water in the pool by the number of hours it takes to drain completely. In this case, the pool holds 10,567.2 gallons of water and it takes 11.8 hours to drain completely. When we divide these two numbers, we get 91.84 gallons per hour.

We can round this number to the nearest hundredth to get 91.85 gallons per hour. This means that the water level in Belvedere's swimming pool will drop by 91.85 gallons every hour until it is completely drained.

It is important to note that this is just an estimate. The actual change in the water level per hour may vary depending on a number of factors, such as the size of the drain, the water pressure, and the temperature of the water.

The total amount due, in dollars, is an illustration of a linear function

The equation of the function is \(y = 25x + 250\)

Represent the month with x, and the total due with y.

Start by calculating the slope (m) using:

\(m = \frac{y_2 -y_1}{x_2 -x_1}\)

So, we have:

\(m = \frac{375 - 300}{5 - 2}\)

Simplify

\(m = \frac{75}{3}\)

Divide 75 by 3

\(m = 25\)

The linear equation is then calculated as:

\(y = m(x - x_1) + y_1\)

So, we have:

\(y = 25(x - 2) + 300\)

Open bracket

\(y = 25x - 50 + 300\)

Add 300 to -50

\(y = 25x + 250\)

Hence, the equation of the function is \(y = 25x + 250\)
