Answer:

Proved

Step-by-step explanation:

Given: EC || AC, DB || AC, ∠A = ∠F

Prove: ΔMDF ∼ ΔNCA

Solution

See diagram attached to the solution to better understand the following workings.

Redrawing ΔMDF or rotating to be facing the same direction.

EC is parallel to AC

DB parallel to AC

Using similar triangle theorem:

If ΔMDF ∼ ΔNCA

Ratio of Corresponding sides would be equal

(adjacent of ΔMDF)/(adjacent of ΔNCA) = (Opposite of ΔMDF)/(opposite of ΔNCA) = (hypotenuse of ΔMDF)/(hypotenuse of ΔNCA)

DF/ CA = MD/NC = FM/AN

∠A = ∠F

∠M = ∠N

∠D = ∠C

Since the ratio of Corresponding sides and angle are equal, ΔMDF is similar to ΔNCA.

ΔMDF ∼ ΔNCA

Statement:

1. line EC is perpendicular to line AC, line is perpendicular to DB line AC, ∠A = ∠F

2. ∠F = ∠A

3. ∠1 =∠2

4. ΔMDF ∼ ΔNCA

Reason:

1. Given

-1/2 + 1/3 = -0.16666666666

Step-by-step explanation:

‑1/2+(3/4•4/9) =

-1/2 + (1/3) = -4/25

-0.16

However true answer is  16666666666/100000000000. = 0.1666666666

The rule is when fractions reoccur, we show closest and -4/25 is closer than -1/6

Final answer:

As the independent variable x grows very large, the quadratic function y = 4x^2 will outpace the linear functions y = 7x, y = 5x, and y = 34, hence it will become the largest and remain so.

Explanation:

The student is asking about the behavior of different linear functions and a quadratic function as the independent variable x becomes very large. When examining the functions given, we notice that three of them, y = 7x, y = 5x and y - 4x are linear, while the fourth, given the context should likely be a quadratic function y = 4x2, although that wasn't presented correctly in the question. As x grows, the function with the highest degree will become the largest. In this case, the quadratic function y = 4x2, which grows at a rate proportional to the square of x, will outpace the linear functions, whose growth is only directly proportional to x. Thus, as x becomes very large, the quadratic function “y = 4x2” becomes the largest and remains so.

Answer:

$5,674.30

Step-by-step explanation:

Use the Compound Amount formula:

A = P(1 + r/n)^(n*t), where r = APR as a decimal fraction = 0.1499

and n = 12 (compounded monthly).

Then A = $2,000(1 + 0.1499/12) )^(7*12)

             =  $2,000(1 +  0.0125)^84

              = $2,000(1.0125)^84 = $2,000(2.837) = $5,674.30

Answer: the probability the mean weight will exceed 2.1 ounces is 0.09

Step-by-step explanation:

Let x be the random variable representing the amount of icing on a Cuppie Cake large cupcake. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/(σ/√n)

Where

x = sample mean

µ = population mean

σ = standard deviation

n = number of samples

From the information given,

µ = 2

σ = 0.3

n = 16

x = 2.1

the probability that the mean weight will exceed 2.1 ounces is expressed as

P(x ≥ 2.1)

For x = 2.1

z = (2.1 - 2)/(0.3/√16) = 1.33

We would determine the probability for the area above z = 1.33 from the normal distribution table. It would be

p = 1 - 0.91 = 0.09

P(x ≥ 2.1) = 0.09

Answer:

E(Bases ) = 0.6584499955929  choice C.

Step-by-step explanation:

We want Expected number of bases during 2009

E(bases) = SUM (number of outcomes) *probabiility of outcome

93 + 45 + 1 + 47   = 176 hits

but there are a total of 568 bats

568 - 176 =   392 misses?

E(Bases) =  0* P( miss) + 1 *  P( hitting singles) + 2*P(hitting doubles) + 3*P(hitting triples) + 4*P(home run)

E(Bases) =  0 + 93/568 +  2* (45/568) + 3*(1/568) + 4*(47/568)

0.16373239  + 0.158450 + 0.0052816901 + 0.33098591549

E(Bases ) = 0.6584499955929

Step-by-step explanation:

1. T1: Translate ABCDE.

2. R1: Rotate the translated polygon.

3. S1: Scale the rotated polygon.

4. F1: Reflect the scaled polygon if needed.

To determine a series of transformations that would map polygon ABCDE onto polygon A'B'C'D'E', you can break down the process into individual steps. Here, I'll describe each transformation step:

1. Translation:

  Translate polygon ABCDE to align its center of mass with the center of mass of polygon A'B'C'D'E'. This ensures that the polygons are roughly in the same position. Let's denote this transformation as "T1."

2. Rotation:

  Rotate the translated polygon so that one of its sides aligns with a side of polygon A'B'C'D'E'. You can use the center of mass as the pivot point for rotation. Denote this transformation as "R1."

3. Scaling:

  Scale the rotated polygon proportionally to match the size of polygon A'B'C'D'E'. This will make sure that the two polygons have the same size. Denote this transformation as "S1."

4. Reflection:

  Reflect the scaled polygon if needed to match the orientation of polygon A'B'C'D'E'. This step may not always be necessary, depending on the orientation of the two polygons. Denote this transformation as "F1" (for reflection).

So, the series of transformations can be written as follows:

1. T1: Translate ABCDE.

2. R1: Rotate the translated polygon.

3. S1: Scale the rotated polygon.

4. F1: Reflect the scaled polygon if needed.

These transformations will map polygon ABCDE onto polygon A'B'C'D'E' while preserving their size and shape.

The length of the diagonal of the rectangular cardboard Hermina cut

is 10√5''.

In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

Given, Hermina cut a 10" by 20" piece of cardboard down the diagonal.

So, The diagonal can be thought of as the hypotenuse of a right-angle triangle with a base 20'' and a height of 10''.

Therefore,

Hypotenuse² = Base² + Height².

Hypotenuse² = 20² + 10².

Hypotenuse² = 400 + 100.

Hypotenuse² = 500.

Hypotenuse = √(500).

Hypotenuse = 10√5''.

The length of the cut (c) is 5 times the square root of 20 inches, which is approximately 22.36 inches when rounded to two decimal places.

When Hermina cuts a 10" by 20" piece of cardboard down the diagonal, she essentially creates two right triangles. The diagonal of a rectangle splits it into two congruent right triangles. This diagonal acts as the hypotenuse of each right triangle.

In a right triangle, we can use the Pythagorean theorem to find the length of the hypotenuse (c) if we know the lengths of the other two sides (a and b).

The Pythagorean theorem states: c^2 = a^2 + b^2, where c is the length of the hypotenuse.

In this case, one side (a) is 10 inches long, and the other side (b) is 20 inches long. Plugging these values into the formula:

c^2 = 10^2 + 20^2

c^2 = 100 + 400

c^2 = 500

Now, to find c, we take the square root of both sides to isolate c:

c = √500

To simplify the square root:

c = √(25 * 20)

c = 5√20

In summary, Hermina's diagonal cut creates two right triangles, and the length of the cut (c) can be found using the Pythagorean theorem. The calculated length is approximately 22.36 inches.

Step-by-step explanation:

Answer:

To be reasonable means to be as much as is appropriate or fair.  

In math, reasonableness can be defined as checking to verify that the result of the solution or the calculation of the problem is correct or not, be either estimating or by plugging in your result to check it.  

When solving a math problem, we can check if the answer we have derived to is reasonable or not, based on an estimate. A reasonable estimate does not exceed the original numbers in a problem.  

For instance, in a division problem like 424 ÷ 4 − 10, we can check is our answer is reasonable or not, by estimating an approximate answer or by plugin gin using the division formula.  

We can round down 424 to the nearest hundreds, to estimate the answer. Since 96 (actual answer)  ≈ 90 (estimate answer), we know our solution is correct.

We can check our solution by plugging in to verify using, 96 × 4 + 10 as well.

Step-by-step explanation:

When estimating an addition or subtraction problem, you can easily tell if it is reasonable or not. If you're having trouble with a problem, such as 1342+7864, and you're getting an answer of... 1300, but don't think its correct, you can estimate by rounding the numbers and adding them. For example, 1342=1300 and 7864=7900 (I'm using the rule that if the number is 4-0 I round down and if its 5-9 I round up.) Since we're woring with thousands you would try to get the most split, even value you can without taking off too much, so we would round the tens place. And after that you could add 1300+7900=9200. Then you would know your answer of 1300 is not reasonable and you have an error in your equation.  Estimating is a great skill to have, and it really helps when you're just trying an equation out or get one of those "Estimate the sum of" questions.
