Traveling at 65 miles/hour, how many feet can you travel in 22 minutes? How do you know?

The equation that represents the translated function for

[tex]\rm f(x) = \dfrac{1}{5}[/tex]   [tex]\rm is\;\; \rm \bold{g(x) = f(x) +4 = 4.2}[/tex].

Given that the function f(x) = 1/5 is translated up 4 units.  

We have to determine the equation that  represents the translated function

The function f(x) = 1/5  as the function is translated.    

Translation is a concept of mathematics . In translation the shape of the object is simply moved linearly from one point to other point by adding some constant values in the previous coordinates. In translation , there  is no dilation shape and size of the object remains the same.

Let us consider that if the function is translated up with 4 units then the new function is [tex]\rm\bold{ g(x)}[/tex]

So according to the language of question we

[tex]\rm g(x) = f(x) +4[/tex]

[tex]\rm g(x) = \dfrac{1}{5} +4 = \dfrac{21}{5} = 4.5[/tex]

[tex]\rm g(x) = 4.5[/tex]

The equation that represents the translated function for

[tex]\rm f(x) = \dfrac{1}{5}[/tex]      [tex]\rm is\;\; g(x) = f(x) +4 = 4.2[/tex]

Answer:

8 Hours!!

Step-by-step explanation:

It will take you 15 minutes to walk one mile at a speed of 4 miles per hour.

To determine how long it will take you to walk one mile, we can use the formula:

Time = Distance / Speed

Let's plug in the values:

Distance = 1 mile

Speed = 4 miles per hour

Time = 1 mile / 4 miles per hour

Time = 0.25 hours

Since there are 60 minutes in an hour, we can convert the time to minutes:

Time = 0.25 hours × 60 minutes per hour

Time = 15 minutes

Therefore, it will take you 15 minutes to walk one mile at a speed of 4 miles per hour.

The present value that will grow to $7,000 if the annual interest rate is 3.5% compounded quarterly for 9 years is $5,187.72

The Breakdown

To find the present value (PV) that will grow to $7,000 if the annual interest rate is 3.5% compounded quarterly for 9 years, you can use the formula for compound interest:

PV = FV / (1 + (r / n))^(n*t

Where:

PV = Present Value

FV = Future Value ($7,000 in this case)

r = Annual interest rate (as a decimal, so 3.5% is 0.035)

n = Number of times the interest is compounded per year (quarterly, so 4 times)

t = Number of years (9 years in this case)

PV = 7000 / (1 + (0.035 / 4))^(4 * 9)

PV = 7000 / (1 + 0.00875)^(36)

PV = 7000 / (1.00875)^36

Now, calculate (1.00875)^36:

(1.00875)^36 ≈ 1.34985880768

Now, divide $7,000 by this value to find the present value:

PV ≈ 7000 / 1.34985880768 ≈ $5,187.72

There are 22,100 possible hands of 3 cards from a 52-card deck using combinations. The probability of dealing three eights in a row from the deck is approximately 0.000181.

This question involves calculating probabilities and combinations related to card hands from a deck of 52 cards.

Possible Hands of 3 Cards:

To determine the number of possible hands of 3 cards from a 52-card deck, we use the combination formula: C(n, k) = n! / [k! * (n - k)!], where n is the total number of cards and k is the number of cards to choose.

C(52, 3) = 52! / [3! * (52 - 3)!] = 52! / (3! * 49!) = (52 × 51 × 50) / (3 × 2 × 1) = 22100. Therefore, there are 22,100 possible hands of 3 cards.

Probability of Dealing Three Eights:

The probability of dealing three eights in a row can be determined as follows:

Therefore, the probability of dealing three eights is: (4/52) × (3/51) × (2/50) = 24 / 132600 = 1 / 5525 ≈ 0.000181.

This detailed explanation helps in understanding how combinations and probabilities in card games are calculated.

The sum of the first 10 terms of the series is 23.

An arithmetic progression(AP) is a sequence or series of numbers such that the difference of any two successive members is a constant. The first term is a, the common difference is d, n is number of terms.

For the given situation,

The series is 0.5,0.9,1.3,1.7.....

Here the first term, a = 0.5,

The common difference, d = [tex]0.9-0.5[/tex]

⇒ [tex]d=0.4[/tex]

Number of terms, n = 10

The formula of sum of n terms is

[tex]S_{n}=\frac{n}{2} [2a+(n-1)d][/tex]

On substituting the above values,

⇒ [tex]S_{10}=\frac{10}{2} [2(0.5)+(10-1)(0.4)][/tex]

⇒ [tex]S_{10}=5 [1+9(0.4)][/tex]

⇒ [tex]S_{10}=5 [1+3.6][/tex]

⇒ [tex]S_{10}=5 [4.6][/tex]

⇒ [tex]S_{10}=23[/tex]

Answer:

Pool needed to be filled = 7623.62 gallons

Step-by-step explanation:

Length of rectangular pool = 24.5 feet

Width of rectangular pool = 13 feet

Depth of rectangular pool = 4 feet

Now, Volume of the pool = Length × Width × Depth

                                          = 24.5 × 13 × 4

                                          = 1274 cubic feet

Now, 1 cubic feet = 7.48 gallons

⇒ 1274 cubic feet = 7.48 × 1274

                              = 9529.52 gallons

So, Volume of the pool = 9529.52 gallons

Now, the pool is to be filled 80%

So, Pool needed to be filled = 9529.52 × 0.80

                                                 = 7623.62 gallons

The number of gallons of water to the nearest tenth, that are needed to fill the pool to 80% capacity is 7623.6 gallons.

First step:

Volume of the pool=Length × Width × Depth

Volume of the pool= 24.5 ft × 13ft × 4ft

Volume of the pool=1274 cubic feet

Second step:

Number of gallons=(7.48 × 1274)×80%

Number of gallons=9529.5 gallons×80%

Number of gallons=7623.6 gallons

Inconclusion the number of gallons of water to the nearest tenth, that are needed to fill the pool to 80% capacity is 7623.6 gallons.

Final answer:

To estimate the product of 3.6 and 7.8 by rounding to the nearest whole number, round 3.6 down to 3 and 7.8 up to 8, making the estimated expression (3)(8).

Explanation:

The student has asked how to estimate the product of 3.6 and 7.8 by rounding each factor to the nearest whole number.

To do this, we look at each factor and determine which whole number it is closest to. For 3.6, we round down to 3 because it is closer to 3 than to 4. For 7.8, we round up to 8 because it is closer to 8 than to 7. Hence, the expression that represents the product of each factor rounded to the nearest whole number is (3)(8).

Answer

Find out the what is the approximate length of the side adjacent to angle C .

To prove

As given

In a right triangle, angle C measures 40°.

The hypotenuse of the triangle is 10 inches long.

Than by using the trignometric identity

[tex]cos\angle C= \frac{Base}{Hypotenuse}\\cos\angle C= \frac{BC}{AC}[/tex]

As shown the diagram is given below

AC= 10 inches , ∠C = 40 °

cos 40 = 0.766 (approx)

Put in the above formula

0.766 × 10 = BC

7.66 = BC

7.7 inches (approx) = BC

Option (b) is correct .

The correct option is Option C [tex]\boxed{{\mathbf{7}}{\mathbf{.66 inches}}}[/tex] .

Further explanation:

The cosine ratio can be represented as,

  [tex]\cos \theta  = \frac{{{\text{base}}}}{{{\text{hypotenuse}}}}[/tex]

Here, base is the length of the side adjacent to angle [tex]\theta[/tex]  and hypotenuse is the longest side of the right angle triangle.

The length of side opposite to angle [tex]\theta[/tex]  is perpendicular that is used for the sine ratio.

Step by step explanation:

Step 1:

From the given information, the observed right angle is attached.

First find the hypotenuse and the base of the right angle triangle.

It can be seen from the attached figure that the side [tex]BC[/tex]  is adjacent to angle [tex]C[/tex]  and the side [tex]AC[/tex]  is the hypotenuse of triangle.

Thus, the [tex]{\text{base}}=BC[/tex]  and [tex]{\text{hypotenuse}}=10[/tex] .

Step 2:

We know that the cosine ratio is [tex]\cos \theta =\frac{{{\text{base}}}}{{{\text{hypotenuse}}}}[/tex] .

Therefore, it can be written as,

 [tex]\cos \theta=\frac{{BC}}{{AC}}[/tex]

Now substitute the value [tex]BC=x[/tex]  and [tex]{\text{AC}}=10[/tex]  in the cosine ratio.

[tex]\begin{aligned}\cos C&=\frac{x}{{10}}\\{\text{co}}s40&=\frac{x}{{10}}\\0.766&=\frac{x}{{10}}\\x&=7.66\\\end{aligned}[/tex]

Therefore, the approximate length of the side adjacent to angle [tex]C[/tex]  is [tex]7.7{\text{ inches}}[/tex]  .

Thus, option C is correct.

When a variable is eliminated from the equation during the equation solving process, the two possible solutions are:

A single unique solution and No solution:

When a variable is eliminated from an equation during the solving process, it results in an equation with only one variable. The two possible solutions are:

A single unique solution: This means that there is one specific value for the remaining variable that satisfies the equation.

No solution: This means that there is no value for the remaining variable that satisfies the equation, resulting in an inconsistent or contradictory statement.

Let's consider an example equation to illustrate these possibilities:

3x + 2y = 10

6x + 4y = 20

To solve this system of equations, eliminate the variable "x" by multiplying the first equation by 2 and subtracting it from the second equation:

[tex](6x + 4y) - 2(3x + 2y) = 20 - 2(10)\\6x + 4y - 6x - 4y = 20 - 20[/tex]

0 = 0

In this case, the variable "x" has been eliminated, and we are left with the equation 0 = 0. This equation is true for all values of "y".

Therefore, the system of equations has infinitely many solutions, and any value of "y" would satisfy the equations.

Since a pelidisi below ( 100 ) is considered undernourished and a pelidisi greater than ( 100 ) indicates overfeeding, with a pelidisi of ( 114 ), this individual is considered to be overfed.

Let's denote the pelidisi as ( P ), the weight in grams as ( W ), and the sitting height in centimeters as ( H). According to the given information, the pelidisi varies directly as the cube root of the person's weight and inversely as the person's sitting height. This relationship can be expressed mathematically as:

[tex]\[ P = k \times \frac{\sqrt[3]{W}}{H} \][/tex]

where ( k ) is the constant of variation.

We are given that a person with a weight of ( 48,820 ) g and a sitting height of ( 78.7 ) cm has a pelidisi of ( 100 ). We can use this information to find the value of ( k ):

[tex]\[ 100 = k \times \frac{\sqrt[3]{48820}}{78.7} \][/tex]

Solving for \( k \):

[tex]\[ k = \frac{100 \times 78.7}{\sqrt[3]{48820}} \]\[ k \approx \frac{7870}{36} \approx 218.611 \][/tex]

Now that we have the value of \( k \), we can find the pelidisi for a person with a weight of \( 54,688 \) g and a sitting height of \( 72.6 \) cm:

[tex]\[ P = 218.611 \times \frac{\sqrt[3]{54688}}{72.6} \][/tex]

Calculating \( P \):

[tex]\[ P \approx 218.611 \times \frac{38}{72.6} \]\[ P \approx 218.611 \times 0.522 \]\[ P \approx 114.14 \][/tex]

Rounded to the nearest whole number, the pelidisi of a person with a weight of ( 54,688 ) g and a sitting height of ( 72.6 ) cm is ( 114 ).

Since a pelidisi below ( 100 ) is considered undernourished and a pelidisi greater than ( 100 ) indicates overfeeding, with a pelidisi of ( 114 ), this individual is considered to be overfed.

M + M/2 + 3M = 54

4M + M/2 = 54

8M + M = 108

9M = 108

M = 12

Now,

N = M/2 = 12/2 = 6
