Answer: edgen

B 2=(1+0.065/12)^12t

Step-by-step explanation:

To the nearest year, it will take about 10.7 years to double the original investment.

In this case, the principal P is $1,000, the interest rate r is 6.5% or 0.065 (in decimal form), the number of times compounded per year n is 12 (compounded monthly), and we want to find the time t when the investment doubles, so A is $2,000.

[tex]2000 = 1000(1 + 0.065/12)^{12t}[/tex]

[tex]2 = (1 + 0.065/12)^{12t}[/tex]

ln(2) = 12t * ln(1 + 0.065/12)

Answer:

That time is  35.4 minutes.

Step-by-step explanation:

The mean time of delivery follows a Normal Distribution pattern.

So we need to apply Z-scores to find out.

99% confidence  in delivery time means  P(z > value) = 0.01  = 1%

So    z > 2.325

so.      Pr [ (x - 21.2) /  6.1   >  2.325 ] = 1%

so  x  >  2.325*6.1 + 21.2

x  >  35.3825 minutes  would be out of the 99th percentile

Final answer:

To calculate the 99th percentile of pizza delivery times, use the z-score corresponding to a 0.99 probability and apply the formula X = μ + (z * σ), where X represents the delivery time, μ is the mean, and σ is the standard deviation.

Explanation:

The student is asking for the 99th percentile of the pizza delivery time, given that the times are normally distributed with a mean of 21.2 minutes and a standard deviation of 6.1 minutes. To find the 99th percentile, one would typically use a z-score table or a statistical software to find the z-value that corresponds to the 0.99 probability. Once the z-score is found, the formula X = μ + (z * σ) is used to calculate the specific time that corresponds to the 99th percentile, where X is the delivery time, μ is the mean delivery time, σ is the standard deviation, and z is the z-score. Since the student is asking for a guaranteed delivery time that covers 99% of the deliveries, this time will be longer than the average to account for the variability represented by the standard deviation.

The graph is stretched vertically, shifted left 5 units, shifted up 7 units.

We have to determine the effect of the transformations on the graph of ƒ(x) = x^2 when changed to ƒ(x) =1/2(x − 5)^2 + 7

The vertex form of the quadratic equation is f(x) = a(x-h)^2 + k.

ƒ(x) =1/2(x − 5)^2 + 7 compare with vertex form therefore we have

a=1/2,h=5 k=7.

a=1/2 means the closer to zero the a value, the wider, so this will stretch vertically.

h=5 and this means that the graph is shifted left 5 units.

k=7 this means that the graph is shifted up 7 units.

The answer is stretched vertically, shifted left 5 units, shifted up 7 units.

Final answer:

The graph of f(x) = x^2 undergoes a vertical compression, horizontal shift to the right by 5 units, and a vertical shift up by 7 units to become f(x) = 1/2(x - 5)^2 + 7, corresponding to option B.

Explanation:

When comparing the original function f(x) = x^2 with the transformed function f(x) = 1/2(x − 5)^2 + 7, we can analyze the effects of transformation as follows:

Vertical Compression: The coefficient 1/2 in front of (x − 5)^2 causes a vertical compression by a factor of 1/2 compared to the original function.

Horizontal Shift: The term (x − 5) inside the function indicates a horizontal shift to the right by 5 units.

Vertical Shift: The constant +7 added outside the square indicates the graph is shifted up by 7 units.

Therefore, the correct description of the transformations applied to f(x) = x^2 to obtain f(x) = 1/2(x − 5)^2 + 7 is option B: compressed vertically, shifted right 5 units, and shifted up 7 units.

When wearing the magic ring, health points increase by 30% more.

Some expressions that could represent how many health points the spell restores are:

1.3(H)

H + 0.3(H)

Hope this helps!! :)

The healing spell with the magic ring restores 130% of the health points, represented as 1.30 imes H.

If Eiko's healing spell restores H health points without the magic ring, then with the ring, the spell's power increases by 30%. Thus, the total healing power with the ring can be expressed as H + 0.30 x H, which can also be simplified to 1.30 x H. This means, with the ring, Eiko would restore 130% of the health points that the spell would normally heal without the ring.

Answer:

New length = [tex]2+7=9[/tex] inches

New width = [tex]2+4=6[/tex] inches

Step-by-step explanation:

Given:

Length of rectangle is 7 inches

Width of a rectangle is 4 inches

The area is increased by 26 square inches when the length and width are increased by the same amount.

To find: new length and width

Solution:

With length of rectangle is 7 inches and width of a rectangle is 4 inches,

area = 7×4 = 28 inches

Let length and width be increased by x inches

New length = x + 7 inches

New Width = x + 4 inches

New area = [tex](x+7)(x+4)=x^2 +11x+28[/tex]

Also, new area = 28 + 26 = 54 square inches.

So,

[tex]28+11x+x^2 =54\\x^2+11x-26=0\\x^2 +13x-2x-26=0\\x(x+13)-2(x+13)=0\\(x-2)(x+13)=0\\x= 2, -13[/tex]

As dimension can not be negative, [tex]x=-13[/tex] is rejected.

So, [tex]x=2[/tex]

New length = [tex]2+7=9[/tex] inches

New width = [tex]2+4=6[/tex] inches

Final answer:

The new dimensions of the rectangle are 6 inches by 9 inches, after increasing both the original width and length by 2 inches to achieve the new area of 54 square inches.

Explanation:

Solution to the Rectangle Problem

The original rectangle is 4 inches wide and 7 inches long, with an area of 28 square inches (since area = width  imes length). When both the length and width are increased by the same amount, the area is 28 inches + 26 inches = 54 square inches. Let's denote the increase in dimension by 'x', thus the new dimensions are (4 + x) inches and (7 + x) inches. The new area is then (4 + x)(7 + x) = 54. Expanding this, we get 28 + 11x + x2 = 54. Simplifying, x2 + 11x - 26 = 0.

To find 'x', we can solve the quadratic equation. Factoring the quadratic, we get (x + 13)(x - 2) = 0, giving us two potential solutions for 'x': -13 and 2. However, since a negative increase in dimension is not possible, we only consider x = 2. Hence, the new dimensions of the rectangle are 6 inches by 9 inches.

Step-by-step explanation:

If MATH is an isosceles Trapezoid, and the measurement of Angle A is 60°, then the Measurement of Angle M would be equivalent to the Measurement of Angle A. Then, using the Same Side Interior Theorem, the Measurement of Angle H would be equal to 180°- 60° (The Measurement of Angle M), which is equal to 120°, C.

Answer:

Answer:

12

Step-by-step explanation:

If you flip the polygon on the right so it looks like the polygon on the left, the scale factor for the small polygon to the big polygon is 32/40 or 4/5.

Now use that scale factor, 4/5, to find the missing length

4/5 = ?/15

5*3 = 15 so 4*3 = ?

? = 12

The missing side of the given polygon is 12 units.

In geometry, a polygon is any closed curve made up of a collection of continuous line segments (sides) without any intersections. Triangles (three sides), quadrilaterals (four sides), and pentagons are the three simplest polygons (five sides).

If you flip the polygon on the right so it looks like the polygon on the left, the scale factor for the small polygon to the big polygon is 32/40 or 4/5.

Let x be the missing side of the polygon.

Now use that scale factor, 4/5, to find the missing length.

4/5 = x/15

5*3 = 15 so 4*3 = x

x = 12

therefore, 12 is the missing side of the given polygon.

Answer:

5.83 or E

Step-by-step explanation:

Use Pythagorean theorem. 5^2+3^2=c^2 because the diameter is perpendicular it cuts the chord in half.

25+9=c^2  

34=c^2

5.83

Answer:

x = 5.83.

Step-by-step explanation:

The diameter bisects the vertical chord so the right triangle has legs 3 and 5.

So x^2 = 3^2 + 5^2

x^2 = 34

x = 5.83.

That is odd - if we work it out another way we get a different answer. I guess that must be because the numbers given in the diagram are not possible.

If we use the intersecting chords theorem,  we get (3+6)*3 = 27

= 5 * y where y is the other leg of the right triangle giving y = 5.4

and then this will give x = 6.18.

Subtracting a negative is the same as adding its positive counterpart. Therefore, (5 - (-7)) can be written as (5 + 7), resulting in the answer of 12. So, 5 - (-7) = 5 + 7.

To write the subtraction problem (5 - (-7)) as an addition problem, we can use the rule that subtracting a negative is equivalent to adding its positive counterpart. Therefore: 5 - (-7) = 5 + 7.

In this case, subtracting a negative 7 is the same as adding 7. The result of this addition is 12. So, 5 - (-7) is equal to (5 + 7) and both expressions evaluate to 12.

This concept is fundamental in understanding the operations of addition and subtraction and their relationship to positive and negative numbers.

To rewrite subtraction as addition, change the sign of the number being subtracted and then add it to the other number. In the equation 5 - (-7), this becomes 5 + 7 because we flip the negative sign to a positive.

The equation 5 - (-7) can be rewritten as addition by changing the subtraction of a negative number to the addition of a positive one. So, replacing the minus sign with an addition sign, and flipping the sign of the second number from negative to positive yields 5 + 7.

The general rule for subtracting integers is to change the sign of the number being subtracted (the subtrahend) and then proceed with addition. For example, 5 - (+3) = 5 - 3 becomes 5 + (-3) = 2. Another example: subtracting -6 from 2 can be rewritten as 2 - (-6) = 2 + 6 = 8. When handling subtraction, this is how we can always rewrite it as an addition problem.

Answer: A Brandon’s sound intensity is 1/4 the level of ahmads mower

Step-by-step explanation:

Brandon's audible sound level is 60 decibels less than the sound intensity level of Ahmad's mower. This is because the sound intensity from the mower is one million times (or 10^6 times) greater than the sound intensity level that Brandon can hear.

The sound intensity, I, is given in terms of decibels, Db, as defined in the formula L = 10 log (I/I0). Here, I0 = 10-12 watts per square meter is the least intense sound a human ear can hear. Now, to compare the sound intensity levels for Brandon and Ahmad's mower, we need to look at their respective sound intensities.

Brandon hears a sound level of 10-10 watts per square meter, and Ahmad's mower generates a sound intensity of 10-4 watts per square meter.

The logarithmic scale used in calculating decibels means that for every increase in 10 times the sound intensity, the loudness increases by 10 decibels.

So, since Ahmad's mower generates a sound that is 106 (=10-4/10-10) times more intense than Brandon's audible level, it means that the mower is 60 decibels louder (since 10*6 = 60) than the sound Brandon can hear.

n(A)=15

Therefore:

[tex]P(A)=\frac{n(A)}{n(S)} =\frac{15}{45} =\frac{1}{3}[/tex]

Final answer:

To find the probability that a randomly selected point with integer coordinates satisfies "x + y ≤ 4", we counted the number of qualifying points and divided by the total number of possible points. With 15 points meeting the condition out of 45 possible points, the probability is 1/3.

Explanation:

The probability question asks for the likelihood that a point (x, y) with integer coordinates will satisfy the condition "x + y ≤ 4" when 0 ≤ x ≤ 8 and 0 ≤ y ≤ 4. To solve this, we first count the total number of possible points with integer coordinates within the given ranges for x and y. Since x can take 9 values (0 through 8) and y can take 5 values (0 through 4), there are 45 possible points (9 times 5).

Next, we identify the points that satisfy the condition "x + y ≤ 4". These points are (0,0), (0,1), (0,2), (0,3), (0,4), (1,0), (1,1), (1,2), (1,3), (2,0), (2,1), (2,2), (3,0), (3,1), and (4,0), which results in a total of 15 points satisfying the condition.

The probability is therefore the number of satisfying points divided by the total number of possible points, which is 15/45 or simplified to 1/3. Thus, the probability that a randomly selected point with integer coordinates will have "x + y ≤ 4" is 1/3.

Out of 58 cities, 26 have either a lake or a river, which simplifies to a fraction of 13/29 of the cities having one of these features.

To find the fraction of 58 cities that have either a lake or a river running through them, we need to determine how many cities have at least one of these features. It is important to check if any city has both a lake and a river, but since the question does not provide this information, we will assume that there are no cities that have both. The question tells us that 3 cities have a lake and 23 have a river. We simply add these counts together to find the total number of cities with at least one water feature.

The calculation would be:

3 (cities with a lake) + 23 (cities with a river) = 26 (cities with a lake or a river)

To find the fraction of the 58 cities that have a lake or a river, we divide the number of cities with a water feature by the total number of cities:

26 (cities with a lake or a river) / 58 (total cities) = 13/29 (simplified fraction).

Final answer:

Of the 58 cities, 26 have either a lake or a river, which means the fraction of cities with a lake or a river is 26/58.

Explanation:

To determine what fraction of the 58 cities have a lake or a river running through them, we must consider that the question does not specify whether some cities might have both a lake and a river. Assuming that the cities with lakes and the cities with rivers do not overlap, we simply add the number of cities with each feature.

There are 3 cities with a lake and 23 with a river. To find the total number of cities with either a lake or a river, we add these two numbers together:

3 (cities with a lake) + 23 (cities with a river) = 26 (cities with a lake or a river).

Now, to find the fraction of the 58 cities that have a lake or a river, we divide the number of cities with water features by the total number of cities:

26 / 58 = fraction of cities with a lake or a river running through them.

To find a fourth vector v₄ that is orthonormal with vectors v₁, v₂, and v₃, you must find the values of v₄ such that the dot product of v₄ and each other vector is zero and v₄'s magnitude is one. This results in a system of linear equations. Solving this system will give you the components of vector v₄.

Given that the vectors v₁=[0.50.50.50.5], v₂=[0.50.5−0.5−0.5], and v₃=[0.5−0.5−0.50.5] are orthonormal, we need to find a fourth vector v₄ in R⁴ such that the set of these four vectors are also orthonormal. In an orthonormal set of vectors, each vector has a length (or magnitude) of one, and the dot product of each pair of different vectors is zero, indicating they are orthogonal or perpendicular to each other.

By inspection, we can see that the given vectors v₁, v₂, and v₃ already satisfy these conditions. So, the challenge is to find v₄ such that its dot product with each of the other three vectors is zero and its magnitude is one. Let's denote v₄ as [a, b, c, d].

Setting the dot product of v₄ and the other three vectors to zero gives the set of equations: 0.5a + 0.5b + 0.5c + 0.5d = 0, 0.5a + 0.5b - 0.5c - 0.5d = 0, and 0.5a - 0.5b - 0.5c + 0.5d = 0. Furthermore, to satisfy the condition that the magnitude of v₄ is one, we have the equation a² + b² + c² + d² = 1.

Solving these simultaneous equations will give the components of the vector v₄ that is orthogonal to v₁, v₂, and v₃ and has a magnitude of one, thus completing the orthonormal set.
