Answer:

The answer to your question is:  The last option is correct

Step-by-step explanation:

Just remember thta when we divide by a negative number, the inequality changes, then,

                            - 125 ≥ -135      divide by -5

                              25  ≤ 27

Answer:

25 < 27 not 25 ≤ 27

Step-by-step explanation:

-125 ≥ -135

on the number, you count through -125 before -135, so -125 is greater but not equal to -135.

-125/ -5  > -135/ -5

= 25 < 27

25 is less than 27. They are not equal.

Answer:

The answer to your question is: 16x + 3

Step-by-step explanation:

Step 1 :      f(x) = 8x² + 3x

                f(x +h) =  8(x + h)² + 3( x + h)

                f(x + h) = 8( x² + 2xh + h²) + 3( x + h)

                f (x + h) = 8x² + 16xh + 8h² + 3x + 3h

Step 2 f(x+h) - f(x) =  8x² + 16xh + 8h² + 3x + 3h - ( 8x² + 3x)

                              = 8x² + 16xh + 8h² + 3x + 3h - 8x² -3x

                              = 16xh + 8h² + 3 h

Step 3 f(x + h) - f(x)/ h = h(16x + 8h + 3) /h

                                    = 16x + 8h + 3

Step 4 lim  f(x + h) - f(x)/ h = lim 16x + 8h + 3  = lim 16x + 8(0) + 3 = 16x + 3

        h ⇒0                           h ⇒0                     h ⇒0

Here, we are required to find the slope of the tangent line to the graph of the given function at any point.

The correct answer is 16x + 3.

The four step process to find the slope of the tangent line to the graph at any point is as follows;

First step (1):

f(x +h) = 8(x + h)² + 3( x + h) and yields;

f(x + h) = 8( x² + 2xh + h²) + 3( x + h)

and, f (x + h) = 8x² + 16xh + 8h² + 3x + 3h.

Second step(2):

F(x+h) - f(x) = 8x² + 16xh + 8h² + 3x + 3h - ( 8x² + 3x)

and, F(x+h) - f(x) = 16xh + 8h² + 3 h

Third step (3):

{F(x+h) - f(x)} / h = (16xh)/h + (8h²)/h + (3 h)/h

This in turn yields;

{F(x+h) - f(x)} / h = 16x + 8h + 3.

Fourth step(4):

lim f(x + h) - f(x)/ h =

h=>0

lim 16x + 8h + 3 = lim 16x + 8(0) + 3 = 16x + 3

h=>0. h=>0

Therefore, the slope of the tangent line to the graph of the given function at any point is;

16x + 3.

The opportunity cost of Susan attending college for a year is $51,400 ($11,400 of actual college expenses and $40,000 of foregone income from her previous job).

The opportunity cost of attending college is determined not only by the actual expenditure but also by the income you forgo by not working. In Susan's case, her actual expenses include $8,000 for tuition, $900 for books, and $2,500 for food, which total to $11,400. However, since she quit her $40,000 a year job to attend college, that lost income is also part of her opportunity cost. So, we add the lost income to her college expenses to get the total opportunity cost. Therefore, the opportunity cost of Susan attending college for the year would be $51,400 ($40,000 + $11,400).

Height of an equilateral angle of side length 88m: [tex]76.21\,m=h[/tex]

Step-by-step explanation:

An equilateral triangle has 3 equal sides and 3 equal angles. The height of the triangle could be expressed as:

[tex]sin(\theta)=\frac{O}{H}[/tex]

[tex]sin(60^o)=\frac{h}{s}[/tex]

Moving s to the other side we find the function for the height:

[tex]sin(60^o)\,\,s=h[/tex]

As we know that s=88m we have

[tex]sin(60^o)\,\,88m=h[/tex][tex]\frac{\sqrt{3}}{2}88m=h[/tex]

[tex]44\sqrt3 \,m=h[/tex]

[tex]76.21\,m=h[/tex]

Explanation of the height of an equilateral triangle as a function of its side length and calculation for a triangle with a side length of 88m.

Justify that the triangles are similar: Equilateral triangles have all sides equal and all angles equal, therefore they are similar.

Write an equation that relates the sides of the triangles using words to describe the quantities: The height h of an equilateral triangle is equal to √3/2 times the side length s.

Rewrite your equation using your symbols: h = √3/2 * s

Algebraically isolate the unknown quantity: Given s = 88 m, plug it into the formula h = √3/2 * s to find the height h.

Plug-in numbers and calculate answer: h = √3/2 * 88 m ≈ 76.12 m

Check answer: The calculated height of approximately 76.12 m seems reasonable for an equilateral triangle with a side length of 88 m.

Answer:

  20 ft

Step-by-step explanation:

The tree's shadow is 34/8.5 = 4 times the length of the person's shadow, so the tree is 4 times a tall as the person:

  4×5 ft = 20 ft . . . . . the height of the tree

_____

Shadow lengths are proportional to the height of the object casting the shadow.

Using the ratio given from the shadow of the 5-foot person, we set up a proportion and solve for the height of the tree, which is 20 feet.

The question is asking about the height of a tree, which can be figured out through a method called similar triangles in geometry. In this case, Phil, Melissa, Noah, and Olivia observed a 5-foot tall person casting an 8.5-foot shadow and a tall tree casting a 34-foot shadow.

From this, we can set up a proportion to find out the height of the tree. This would look like 5/8.5 = x/34, where x is the height of the tree. Cross multiplying and solving for x gives us x = (5*34)/8.5, which equals to 20 feet. Therefore, the height of the tree is 20 feet.

Answer:

$300

Step-by-step explanation:

If there is a 30% reserve requirement on a $1,000 deposit, there must be $300 set aside as a member bank reserve.

30% of $1000 = $300

So Julia... 6 miles in 30 minutes. Let's find out how much she travelled in 1 hour. Multiply it by 2, since 30 x 2 = 60 mins = 1 hour, you get 12 miles per hour for Julia.

For Alex... 2 miles in 12 minutes. Multiply it by 5, as 12 x 5 = 60 mins = 1 hour, you get 10 miles per hour for Alex.

Julia travelled faster. She travelled 12 miles per hour while Alex travelled 10 miles per hour.

Julia travelled at a greater speed at 12 miles per hour.

Answer:

  15 cups

Step-by-step explanation:

To make 15 lattes, Charles will triple his recipe, so use 3×5 = 15 cups of milk.

The values for x and y are as follows: ( x = 25 ) feet and ( y = 15 ) feet.

To find the values of x and y, we can set up a system of equations based on the given information. Let( x ) be the side length of the large square and ( y ) be the side length of the small square. The perimeter of the entire fence is given by ( 4x + 4y = 350) feet, and the total area enclosed by the fence is( xy + xy = 2xy = 6125 ) square feet.

First, we solve the perimeter equation for  x

4x + 4y = 350

[tex]\[ x + y = \frac{350}{4} \][/tex]

x + y = 87.5

Now, we have two equations:

x + y = 87.5

2xy = 6125

We can substitute the value of ( x + y ) from the first equation into the second equation:

2xy = 6125

2(87.5 - y)y = 6125

175y - 2y² = 6125

y² - 87.5y + 3062.5 = 0

Solving the quadratic equation, we find two possible values for  y  However, since the side length cannot be negative, we discard the smaller value, leaving us with y = 15  feet. Substituting this into the first equation, we find x = 25feet.

Therefore, the final answer is x = 25 feet and  y = 15  feet.

By the law of total probability,

[tex]P(A\cap B)=P[(A\cap B)\cap C]+P[(A\cap B)\cap C'][/tex]

but the events A, B, and C are mutually independent, so

[tex]P(A\cap B)=P(A)P(B)[/tex]

and the above reduces to

[tex]P(A)P(B)=P(A)P(B)P(C)+P(A\cap B\cap C')\implies P(A\cap B\cap C')=P(A)P(B)(1-P(C))=P(A)P(B)P(C')[/tex]

which is to say A, B, and C's complement are also mutually independent, and so

[tex]P(A\cap B\cap C')=0.5\cdot0.8\cdot(1-0.3)=0.12[/tex]

By a similar analysis,

[tex]P(A\cap B'\cap C)=P(A)P(B')P(C)=0.03[/tex]

[tex]P(A'\cap B\cap C)=P(A')P(B)P(C)=0.12[/tex]

These events are mutually exclusive (i.e. if A and B occur and C does not, then there is no over lap with the event of A and C, but not B, occurring), so we add the probabilities together to get 0.27.

Final answer:

The probability that exactly two of the independent events A, B, and C occur is 0.43, calculated by adding the probabilities of each possible pair of events occurring while the third does not.

Explanation:

The student is seeking the probability that exactly two out of the three events A, B, and C occur given their individual probabilities P(A) = 0.5, P(B) = 0.8, and P(C) = 0.3, and the fact that they are mutually independent events. To find this, we ned to consider the three scenarios where exactly two events occur: A and B, A and C, and B and C. The probability for each scenario is found by multiplying the probabilities of the two events occurring and then multiplying by the probability of the third event not occurring.

For example, the probability of A and B both occurring but not C is P(A) × P(B) × (1 - P(C)). To find the total probability that exactly two events occur, we sum up the probabilities of all three scenarios:

P(A and B but not C) = P(A) × P(B) × (1 - P(C))

P(A and C but not B) = P(A) × (1 - P(B)) × P(C)

P(B and C but not A) = (1 - P(A)) × P(B) × P(C)

We then calculate and sum these probabilities:

P(A and B but not C) = 0.5 × 0.8 × (1 - 0.3) = 0.5 × 0.8 × 0.7 = 0.28

P(A and C but not B) = 0.5 × (1 - 0.8) × 0.3 = 0.5 × 0.2 × 0.3 = 0.03

P(B and C but not A) = (1 - 0.5) × 0.8 × 0.3 = 0.5 × 0.8 × 0.3 = 0.12

Adding these probabilities together provides the final answer:

Σ P(exactly two events) = 0.28 + 0.03 + 0.12 = 0.43

Therefore, the probability that exactly two of the events A, B, and C occur is 0.43.

Answer:

Step-by-step explanation:

Given that When n is divided by 21, the remainder is an odd number.

i.e. [tex]n=21m+k[/tex] where m is an integer and k a positive integer <21

When n is divided by 28, the remainder is 3

[tex]n=28c+3[/tex], where c is a positive integer

This can be written as

[tex]n=4(7c)+3\\n=7(4c)+3[/tex]

Since n is giving odd remainder when divided by 21,

we get r =3 as n is a multiple of 7 +3

125 liters of pure peroxide should be added to the 500 liters of the 10% solution to produce a new product that is 28% peroxide.

The concentration C of the new mixture is given by the formula:

C = (x + 0.1 * 500) / (x + 500)

We want to find out how many liters of pure peroxide (100% peroxide) should be added to produce a new product that is 28% peroxide.

In other words, we want to find the value of x that makes C equal to 0.28 (28%).

So, we set up the equation:

0.28 = (x + 0.1 * 500) / (x + 500)

Now, we can solve for x:

0.28(x + 500) = x + 0.1 * 500

Distribute 0.28 on the left side:

0.28x + 0.28 * 500 = x + 0.1 * 500

Simplify:

0.28x + 140 = x + 50

Subtract x from both sides:

0.28x - x + 140 = 50

-0.72x + 140 = 50

Subtract 140 from both sides:

-0.72x = -90

Divide by -0.72:

x = 125

So, 125 liters of pure peroxide should be added to the 500 liters of the 10% solution to produce a new product that is 28% peroxide.

#SPJ12

Final answer:

To achieve a 28% peroxide concentration, approximately 125 liters of pure peroxide should be added to the existing 500-liter, 10% peroxide solution.

Explanation:

The question asks how many liters of pure peroxide (x liters) must be added to a 500-liter solution with a 10% peroxide concentration to produce a new product that is 28% peroxide. To solve this, we'll set up the equation:

C = (x+0.1(500)) / (x+500) where C = 0.28 (the target concentration). So,

0.28 = (x + 50)/(x + 500)

Multiply both sides by (x + 500) to get 0.28(x + 500) = x + 50

Distribute 0.28 to get 0.28x + 140 = x + 50

Subtract 0.28x from both sides to isolate x on one side: 140 = 0.72x + 50

Subtract 50 from both sides: 90 = 0.72x

Divide both sides by 0.72 to solve for x: x ≈ 125 liters

Therefore, approximately 125 liters of pure peroxide should be added to the 500-liter solution to achieve a 28% peroxide concentration.

Because there are 4 inside angles the sum of the four angles must equal 360 degrees.

Add the angles to equal 360:

4x + 3x + 2x + 3x = 360

Simplify:

12x = 360

Solve for x by dividing both sides by 12:

x = 360 /12

x = 30

Now you have x, solve for each angle:

ABC = 4x = 4 x 30 = 120 degrees.

BCD = 3x = 3 x 30 = 90 degrees.

CDA = 2x = 2x 30 = 60 degrees.

DAB = 3x = 3 x 30 = 90 degrees.

C. It's important to know that a four sides figure needs the inside angles when added together need to equal 360 degrees.

(b) Put 5 1/8 for s in the above equation and solve.

  |5 1/8 - x| ≤ 3/16

  -3/16 ≤ 5 1/8 -x ≤ 3/16

  3/16 ≥ x -5 1/8 ≥ -3/16 . . . . multiply by -1 to get positive x

  5 5/16 ≥ x ≥ 4 15/16 . . . . . . add 5 1/8

Pieces may be between 4 15/16 and 5 5/16 inches in length.

An absolute value inequality can be used to represent the acceptable range of lengths for a piece of wood in a woodshop class. For a specified length of 5 1/8 inches, the acceptable lengths for the piece would be between 4 15/16 inches and 5 5/16 inches.

Your task in woodshop class is to cut pieces of wood to within 3/16 inch of the teacher's specifications. The difference between the specification s and the measured length x of a cut piece is represented by (s-x).

(a) You can represent this situation with the absolute value inequality |s - x| ≤ 3/16, which shows that the difference between the specification and the measured length must be less than or equal to 3/16 inch.

(b) If the length of one piece is specified to be s = 5 1/8 inches, you can substitute that value into the inequality to find the acceptable range of lengths: |5 1/8 - x| ≤ 3/16. Solving the inequality gives you the range 5 - 3/16 inches ≤ x ≤ 5 + 3/16 inches, or between 4 15/16 inches and 5 5/16 inches.

[tex]EF=AC-AB=10-7=3\ units[/tex]

[tex]CF=BE=7\ units[/tex]

substitute

[tex]A=(3)(7)=21\ units^2[/tex]

step 5

sum the shaded areas

[tex]14+21=35\ units^2[/tex]

step 6

Divide the area of  of the shaded region by the area of ACIG

[tex]\frac{35}{90}[/tex]

Simplify

Divide by 5 both numerator and denominator

[tex]\frac{7}{18}[/tex]

therefore

The fraction of the area of ACIG represented by the shaped region is 7/18

Answer:  [tex]\dfrac{1}{3}[/tex]

Step-by-step explanation:

Given : An opaque bag contains 5 green marbles, 3 blue marbles and 2 red marbles.

Total marbles = 5+3+2=10

Now, if it given that the a red marble is already drawn, then the total marbles left in the bag = 10-1=9

But the number of blue marbles remains the same.

Now, the probability of drawing a blue marble given the first marble was red :-

[tex]=\dfrac{\text{Number of blue marbles}}{\text{Total marbles left}}\\\\=\dfrac{3}{9}=\dfrac{1}{3}[/tex]

Hence, the required probability = [tex]\dfrac{1}{3}[/tex]

Answer:

  225%

Step-by-step explanation:

You can figure the percentage change from ...

  percentage change = ((new value)/(old value) -1) × 100%

  = (26/8 -1) × 100% = (3.25 -1) × 100% = 225%
