An evergreen nursery usually sells certain shrub after 6 years of growth and shaping: The growth rate during those 6 years is approximated by dh/dt = 1.2t + 2, where t is the time in years and h is the height in centimeters. The seedlings are 15 centimeters tall when planted (t = 0). (a) Find the height after years h(t) (b) How tall are the shrubs when they are sold? cm

Proof:

Let's start of by solving for the length of AC, which is just the sum of lengths AB and BC, which is 10 + 3 = 13 units.

Because of our second given, AC ≅ EG, we know that EG is also 13 units in length. Also, from our first given, BC ≅ EF, we know that EF is 3 units.

We also know that the length of EG is the sum of lengths EF and FG so we can write the equation

EG = EF + FG

13 = 3 + FG

FG = 10 meaning FG is 10 units

The value of the amount will be $721.40.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

500 dollar deposit for 20 years with a interest rate of 2%.

Now,

We know that;

The formula for amount is,

⇒ [tex]A = P (1 + r)^n^t[/tex]

Where, A is total amount, P is principle amount, r is interest rate.

Here, We have;

P = $500

t = 20 years

r = 2%

Substitute all the values, we get;

⇒  [tex]A = P (1 + r)^n^t[/tex]

⇒ [tex]A = 500 (1 + 0.02)^2^0[/tex]

⇒ A = 500 × 1.02²⁰

⇒ A = 500 × 1.44

⇒ A = $721.40

Thus, The value of the amount = $721.40

Therefore ,the water level is rising  by 0.1388 ft/min when h is 1.2 feet deep and  the water is being pumped at rate of 0.8625 cubic feet per min when water is rising at 3/8 inch/min

A three-dimensional space's occupied volume is measured. It is typically quantified using a variety of imperial or US-standard units as well as SI-derived units. The concept of length and volume are related.

Here,

Given: A trough has a 12 foot length and a 3 foot top width. Three-foot-high isosceles triangles make up its ends. 12f 3 ft 31

So the first case:

using this we find the rate of Volume,

So,

=> dV/dt = length * height *dh/dt

=> dV/dt = 12 * 1.2 *dh/dt

=> 2 = 12*1.2* dh/dt

=> 2 = 14.4 * dh/dt

=>dh/dt = 2/14.4

=>dh/dt = 0.1388 ft/min

Therefore ,the water level is rising  by 0.1388 ft/min when h is 1.2 feet deep .

Second case:

Since water level is rising by 3/8 inch per min =0.03125 feet/min

=> dV/dt = length * height *dh/dt

=> dV/dt = 12 * 2.3 *0.03125

=>dV/dt = 0.8625 cubic feet per min

Therefore , the water is being pumped at rate of 0.8625 cubic feet per min.

The statement "let c and d be disjoint compact subspaces of the Hausdorff space x and then there exist disjoint open sets u and v containing c and d, respectively." is proved.

Here we have given the let A and B be disjoint compact subspaces of the Hausdorff space X.

And we have to prove the statement.

According to the given question, let us consider that x be an arbitrary coordinate of A and here the points of x isn't in Y because A and B are disjoint.

Then according to Lemma 26.4 disjoint open sets Ux and Vx such that x Î Ux and Ux contain B.

Here the collection {Ux} is a covering of A by sets open in X.

And the finite collection of them {U1, ..,Un} covers A because A is compact.

Here the open set U = U1 U....U Un contains A and it is disjoint from

Vanessa can buy a maximum of x oranges, where x is the number of oranges she can buy at the store. We can represent this mathematically as an inequality by letting x represent the number of oranges she can buy and setting it equal to the total amount of money she has minus the cost of the eggs divided by the cost of each orange:

x ≤ ($20 - $3) / $0.50

This inequality tells us that Vanessa can buy at most x oranges as long as the total cost of the oranges (x * $0.50) is less than or equal to the amount of money she has remaining after buying the eggs ($20 - $3).

In other words, Vanessa can buy at most x oranges as long as the total cost of the oranges is less than or equal to $17.50. This means she can buy at most 35 oranges, since 35 * $0.50 = $17.50. Therefore, the inequality that represents the maximum number of oranges Vanessa can buy is:

x ≤ 35.

You could use 1 3/4's of a cup and 8 1/4's of a cup.

1 of the 3/4 cups is 3/4 so that covers the 3/4 of the cups of how much flour is needed.

8 of the 1/4 cups is 8/4 which is equal to 2 so that covers the rest of the flour needed.

And 2 + 3/4 is 2 3/4 which is the amount of flour that is needed.

OR

You could use 3 3/4's of a cup and 2 1/4's of a cup.

3/4 + 1/4=4/4

3/4+1/4=4/4

4/4 + 4/4 is the same thing as 1+1 which is 2, so that covers the 2 cups of the flour that is needed, and then you add another 3/4, now you have

2 3/4, which is the amount of flour needed.

The representation table given indicates that the function is linear, as the difference between consecutive y-values (9-8, 8-7, and 7-6) is constant. Therefore, we can represent the function with a linear equation of the form y = mx + b, where m is the slope and b is the y-intercept.

To find the equation of the function, we can use the x- and y-values given in the table to solve for m and b. For example, using the x- and y-values (-3,9) and (-2,8), we can solve the equation 9 = m(-3) + b for m and b:

9 = -3m + b

8 = -2m + b

Subtracting the second equation from the first equation gives us:

1 = -m

So the slope of the function is -1. Substituting this value back into either equation gives us:

9 = -3(-1) + b

9 = 3 + b

6 = b

So the y-intercept of the function is 6. Therefore, the equation of the function is y = -1x + 6.

The other two representations can be solved in the same way to find the equations of those functions.

It is a number calculated from a statistical test that describes how you are found a particular set of observation ,if the null hypothesis were true.P-values are used in hypothesis testing to help to decide whether to reject the null hypothesis .The lower the p-value the greater the statistical significance of observation differences.

The null hypothesis states that as the assumption that there is no change , no difference and no relationship between two variables.The alternate hypothesis stated that there is a change, difference and relationship between two variables or group.

let we use p-value test

Let u=average time spend on deliveries

so,null hypothesis H0;u[tex]\leq[/tex]34 minutes

    alternate hypothesis HA; u >34

Now the decision rule based on the p-value to whether null hypothesis should be accepted or rejected is given by;

.If the p-value of test statistical is more than the level of significance.then we will not reject our null hypothesis.
