At a certain vineyard it is found that each grape vine produces about 10 lb of grapes in a season when about 800 vines are planted per acre. for each additional vine that is planted, the production of each vine decreases by about 1 percent. so the number of pounds of grapes produced per acre is modeled by
a(n) = (800 + n)(10 − 0.01n)
where n is the number of additional vines planted. find the number of vines that should be planted to maximize grape production.

Answers

Answer 1

Planting an additional 210 vines will maximize grape production.

How to maximize grape production?

To find the number of vines that should be planted to maximize grape production, we need to find the maximum value of the function A(n) = (800 + n)(10 - 0.01n), which represents the number of pounds of grapes produced per acre as a function of the number of additional vines planted. To find the maximum value, we can take the derivative of A(n) with respect to n and set it equal to zero.

A'(n) = -0.01n² + 2.1n + 800

Setting A'(n) = 0, we get

-0.01n²+ 2.1n + 800 = 0

Solving for n using the quadratic formula, we get

n ≈ 210

Therefore, planting an additional 210 vines will maximize grape production.

Determined three ways have a total cost of six dollars each apple cost $1.50 each banana cost $.30 and there’s two more bananas then apples.

Answers

The cost of the apples is 2.9 dollars.

The cost of the bananas is 5.7 dollars.

How to find the number of fruits bought?

The total cost is 6 dollars, each apple cost $1.50 each banana cost $.30 and there’s two more bananas then apples.

Therefore,

let

x = number of apples

y = 2x

where

y = number of bananas

Therefore, using equations,

1.5(x) + y(0.30) = 6

Hence,

where

y = 2x

1.5(x) + 2x(0.30) = 6

1.5x + 0.6x = 6

2.1x = 6

divide both sides by 2.1

x = 6 / 2.1

x = 2.9 dollars

Kayla wants to plant a garden that contains only tomatoes and squash. She only has enough space to plant 40 vegetables, and she only has $80 to spend. Tomatoes cost $1 per plant and squash costs $3 a plant. Let t represent tomatoes and s represent squash. Write a system of equations for the question above. How many tomatoes and how many squash can Kayla plant?

Answers

Solving a system of equations, we see that she can plant 20 tomatoes and 20 squashes.

How many tomatoes and how many squash can Kayla plant?

Let's define the variables:

t = number of tomatoes.s = number of squaches.

The space is enough for 40 plants, then:

t + s = 40

And we know that she has a total of $80 to spend (we assume that she spends it all)

t*$1 + s*$3 = $80

Then our system of equations:

t + s = 40

t*$1 + s*$3 = $80

To solve this, we can isolate one of the variables in the first equation, for e xample if we isolate t, we get:

t = 40  - s

Now we can replace that in the other equation:

(40 - s)*$1 + s*$3 = $80

Now we can solve that for s:

$40 - s*$1 + s*$3 = $80

s*$2 = $40

s = $40/$2 = 20

Then she will buy 20 units of squash, and the other 20 plants will be tomatoes.

write s=∑n=4[infinity]1n(n−1) as a telescoping series and find its sum.

Answers

The sum of the series s = ∑n=4^∞ 1/(n(n−1)) is 1/4.

To write the series s = ∑n=4^∞ 1/(n(n−1)) as a telescoping series, we need to manipulate the terms to cancel each other out and simplify the expression.

We can rewrite the series as:

s = ∑n=4^∞ (1/n - 1/(n-1))

Expanding the summation:

s = (1/4 - 1/3) + (1/5 - 1/4) + (1/6 - 1/5) + ...

Notice that the term -1/(n-1) in each subsequent term cancels out with the 1/n term in the next term, except for the first term (1/4 - 1/3).

We can simplify the expression by canceling out the terms:

s = 1/4 - 1/3 + 1/5 - 1/4 + 1/6 - 1/5 + ...

The consecutive terms cancel out, leaving only the first term:

s = 1/4

Therefore, the sum of the series s = ∑n=4^∞ 1/(n(n−1)) is 1/4.

In kite ABCD, mZBAE = 28° and mZBCE = 58°. Find mLABE.

QuestionExampleStep by StepIn kite ABCD, mZBAE = 28 and mZBCE = 58. Find mLABE.

Answers

Answer:

\(m\angle ABE=52^\circ\)

Step-by-step explanation:

Angles and Lines

The figure shows a kite ABCD where the following data is given:

\(m\BAE=28^\circ\)

\(m\BCE=58^\circ\)

We also know

\(BC\cong CD\)

\(AB\cong AD\)

Since triangle BCD is isosceles, it follows that:

\(m\angle CBE=m\angle CDE\)

And triangles BCD and DCE are congruent.

Thus:

\(m\angle BCE=m\angle DCE=58^\circ\)

And also:

\(m\angle BCE=58^\circ+58^\circ=116^\circ\)

Since the sum of internal angles of BCD is 180°

\(m\angle CDE=m\angle CBE= ( 180 - 116 ) / 2=32^\circ\)

The sum of angles of triangle CDE is 180°, thus

\(m\angle CED=180^\circ - 32^\circ - 58^\circ = 90^\circ\)

Angles CED and BEA are vertical (opposite), thus:

\(m\angle BCE=m\angle CED= 90^\circ\)

Finally, since the sum of the angles of triangle ABE is 180°

\(m\angle ABE= 180 - 90 - m\angle BAE\)

\(m\angle ABE= 180^\circ - 90^\circ - 28^\circ = 52^\circ\)

Two dice are cast. What is the probability that the sum of the two numbers does not exceed 10 (i.e. is less than or equal to 10)?

Answers

The probability is approximately 0.9167 or 91.67%.

To find the probability that the sum of two dice numbers does not exceed 10, we need to determine the favorable outcomes (sums less than or equal to 10) and the total possible outcomes when rolling two dice.

There are 36 possible outcomes when rolling two dice because each die has six faces (1, 2, 3, 4, 5, and 6), and the total number of outcomes is obtained by multiplying the number of outcomes for each die (6 * 6 = 36).

Now let's determine the favorable outcomes (sums less than or equal to 10):

When the sum is 2: There is only one combination (1 + 1).

When the sum is 3: There are two combinations (1 + 2 and 2 + 1).

When the sum is 4: There are three combinations (1 + 3, 2 + 2, and 3 + 1).

When the sum is 5: There are four combinations (1 + 4, 2 + 3, 3 + 2, and 4 + 1).

When the sum is 6: There are five combinations (1 + 5, 2 + 4, 3 + 3, 4 + 2, and 5 + 1).

When the sum is 7: There are six combinations (1 + 6, 2 + 5, 3 + 4, 4 + 3, 5 + 2, and 6 + 1).

When the sum is 8: There are five combinations (2 + 6, 3 + 5, 4 + 4, 5 + 3, and 6 + 2).

When the sum is 9: There are four combinations (3 + 6, 4 + 5, 5 + 4, and 6 + 3).

When the sum is 10: There are three combinations (4 + 6, 5 + 5, and 6 + 4).

Adding up the favorable outcomes, we get: 1 + 2 + 3 + 4 + 5 + 6 + 5 + 4 + 3 = 33.

Therefore, the probability that the sum of the two dice numbers does not exceed 10 is given by:

Probability = Favorable outcomes / Total outcomes = 33 / 36 = 11/12 ≈ 0.9167.

So, the probability is approximately 0.9167 or 91.67%.

ac + adi + bci + bdi²

(ac − bd) + (ad + bc)i

Matching coefficients:

30 < ac − bd < 80

ad + bc = 0

We need to pick four integers between -9 and 9 such that these two equations are satisfied.  One possible combination is:

a = 8, b = -4, c = 6, d = 3

The number would be:

ac − bd = (8)(6) − (-4)(3) = 60

Letters x, y, and z are angle measures. The following equations would ensure that lines p and q are parallel: x = z ; x + y = 180°

A Equation is a numerical explanation that is comprised of two articulations associated by an equivalent sign. In its simplest form in algebra, an equation is a statement that demonstrates that two mathematical expressions are equal.

The image with the angles x, y, and z, as well as the lines p and q, can be found in the link at the answer's conclusion.

Using the image provided;

We can see that the two parallel lines p and q are divided by a transverse line. As a result,

We can say that because we can see that x and z are angles that correspond to one another; Second, we can see that y and z are supplementary angles due to the fact that they form a straight line and that the sum of straight angles is 180 degrees.

therefore; We can say that, using the negotiation property of equivalency, y + z = 180° because x = z.
