find an equation with vertical asymptotes 1 and 4 and horizontal asymptote 1 please help

Answer:

The very first line has an error.

Step-by-step explanation:

When you are solving the second system of equations for y, you need to subtract 3x from both sides and therefore it should be negative.

3x + y = -9

y = -3x - 9

Since the 3x isn't negative in the first line, there is an error.

Answer:

117 girls

Step-by-step explanation:

If 64% are boys, the percentage of girls can be found by subtracting this amount from 100:

100 - 64 = 36

So 36% of 325 are girls.

To find the amount from a percentage use the following formula:

Original amount * [tex]\frac{percentage}{100}[/tex]

Now plug these values in:

[tex]325 * \frac{36}{100}[/tex] = 117

So there are 117 girls in the 325 children.

Answer:

117

Step-by-step explanation:

If 64% are boys, then 36% are girls. 36% of 325 equals 117, so there are 117 girls at the zoo.

Answer:

each person owe $10.26

Step-by-step explanation:

Six friends go out to lunch and decide to split the bill evenly. The bill comes to $61.56.

Total bill for 6 friends = $61.56

To find bill cost for 1 person we divide the total cost by 6

Bill for each person = [tex]\frac{61.56}{6}= $10.26[/tex]

So each person owe $10.26

Answer:

Step-by-step explanation:

For a rectangular prism of dimensions L × W × H, pairs of opposite faces will have dimensions ...

These will be three different sets of dimensions if L, W, and H are all different lengths.

The best way to plot them is by month.

170 - 110 = $60.

We are supposed to plot in months and the above calculation is in year, convert it into months

60/5 = $5 each month

So, the coordinates would be 0, 110 1, 115 2, 120 3, 125

The month will be in the x axis and your money will be the Y axis 

A suitable y-axis scale to plot spending habits ranging from $110 to $170 would start at $100 and go up to $180, while a good interval for the y-axis would be $10 to allow for clear plotting of values in whole dollars.

To answer the student's question about how to plot spending habits on a coordinate grid:

Answer:

Step-by-step explanation:

1. according to the condition

[tex]\frac{price \ radio1}{price \ radio2} =\frac{x}{y}[/tex]

2. when the both prices are increased the ratio is

[tex]\frac{x+20}{y+20}=\frac{5}{2}[/tex]

3. when the both prices are reduced the ratio is

[tex]\frac{x-25}{y-25} =\frac{5}{1}[/tex]

4. using the equations written in steps 2&3 it is possible to make up the system of the two equations:

[tex]\left \{ {{\frac{x+20}{y+20}=\frac{5}{2}  } \atop {\frac{x-25}{y-25}= \frac{5}{1} }} \right.[/tex]

where x=160; y=52.

... V = (7/5)³ × 50 m³ = 2.744 × 50 m³

... V = 137.2 m³

Answer:

6

Step-by-step explanation:

Since the relationship is proportional, when y is increased by a factor of 3 from 7 to 21, so is x—from 2 to 2×3 = 6.

y = x⁴ +4x³ +4x² +4x +3

The coefficients of the offered quartics (in order) have 1, 1, 1, and 0 sign changes, respectively. Descartes' rule of signs tells you this means the first three choices all have one (1) positive real root, so the negative real roots -1 and -3 are not the only ones.

The only possible polynomial is the last one. Synthetic division of that polynomial by roots -1 and -3 leave the remaining factor as x²+1, which has only complex zeros.

The appropriate choice is ...

... y = x⁴ +4x³ +4x² +4x +3

Answer:

d = 8t

Step-by-step explanation:

To find a correlation, you need to find what numbers correlate and how.

Lets try multiplying the t value by 8 to get the value ( as one value is 1 and the other is 8 so it would seem suitable)

1 * 8 = 8

2 * 8 = 16

Both values match up which means that to get d, you multiply t by 8.

This means that your answer is d = 8t.

If the function has a ∪ shape (opens up), then it only goes so low—has a minimum value.

Any even-degree function with a positive leading coefficient will open up, so have a minimum. Your function is degree 2 (even) and has a leading coefficient of 3 (positive).

_____

Comment on other polynomial functions

If the leading coefficient of an even-degree function is negative, it will have an inverted-U shape (∩), so will have a maximum.

Any odd-degree function will have a generally rising (/) or generally falling (\) shape, depending on the sign of its leading coefficient. If positive, then rising; if negative, then falling.

Answer:

Step-by-step explanation:

These sorts of calculations are best done with a calculator that knows statistics.

a) The z-value of the limit ofv interest is (45,000 -35,551)/(5100) ≈ 1.8743. The empirical rule tells you between 16 and 2.5% of the distribution will lie above a limit that is between 1 and 2 standard deviations. So, our calculator value of 3% is approximately correct.

b) The standard deviation of the sample mean is reduced by a factor of √75 from that of the parent distribution for a sample size of 75. Then the z-value is ...

... (38,000 - 35,441)/(5100/√75) ≈ 2559/588.90 ≈ 4.345

The probability of exceeding this valus is pretty small, about 6.95×10^-6.

Answer: The value of [tex]x^2+y^2[/tex] is 140

Step-by-step explanation:

We are given an expression:

[tex](x-y)^2=100[/tex]

And,

xy = 20

Using the identity:

[tex](a-b)^2=a^2+b^2-2ab[/tex]

Solving the expression:

[tex]x^2+y^2-2xy=100[/tex]

Putting the value of 'xy' in above equation, we get:

[tex]x^2+y^2-2(20)=100\\\\x^2+y^2=100+40\\\\x^2+y^2=140[/tex]

Hence, the value of [tex]x^2+y^2[/tex] is 140

The point (3, 18) on the graph means the snail's position when the time is 3 units of time from the time reference is 18 units of distance from the the reference point for distance.

_____

We cannot conclude anything else. We don't know if the snail is moving (or has moved), or if there are any other points on the graph.

Answer: B) The snail traveled 18 ft in 3 h.

Step-by-step explanation: If you look at the graph they graphed (3, 18) the left side says distance (ft) and the dot is to the right of the 18 so it traveled 18 feet.  At the bottom it says time (h) and the dot above the 3 so it took to travel 8 feet.

Answer:

[tex]Height=\sqrt{\frac{weight}{\text{body mass index}}}[/tex]

Step-by-step explanation:

We have BMI formula that is body mass index formula which is:

[tex]\text{Body mass index}=\frac{weight}{height^2}[/tex]

Now, we have to arrange the formula for height:

we will rearrange the terms and derive the formula for height in terms of weight and height.

[tex]Height^2=\frac{weight}{\text{body mass index}}[/tex]

Hence, the required result is:

[tex]Height=\sqrt{\frac{weight}{\text{body mass index}}}[/tex]

Answer:

.325

Step-by-step explanation:

If she had a quiz on 13 of the 40 days , the fraction is 13/40

13/40 = .325

Answer: The fraction of the days on which the quiz has been held expressed as a decimal is 0.325

Step-by-step explanation:

Decimal numbers are not considered as integers. They are rounded off to write an integer.

Fraction is present in the form of [tex]\frac{p}{q}[/tex] where [tex]q\neq 0[/tex]

We are given:

Number of days, the class had quiz = 13

Total number of days = 40

The fraction becomes: [tex]\frac{13}{40}[/tex]

Expression this as a decimal = 0.325

Hence, the fraction of the days on which the quiz has been held expressed as a decimal is 0.325

Given : The Cost of Laptop in 2007 is $1250

Given : The Cost of Laptop in 2009 is $1100

Decrease in Price of Laptop from 2007 to 2009 : (1250 - 1100) =  $150

A) Percent Decrease in the Price of the Laptop from 2007 to 2009 is :

[tex]\mathsf{\implies \frac{Decrease\;in\;Price\;of\;Laptop\;from\;2007\;to\;2009}{Price\;of\;Laptop\;in\;2007} \times 100}[/tex]

[tex]\mathsf{\implies \frac{150}{1250} \times 100}[/tex]

[tex]\mathsf{\implies 12\%}[/tex]

Given : Decrease in Price of Laptop from 2009 to 2010 = $165

B) Percent Decrease in the Price of the Laptop from 2009 to 2010 is :

[tex]\mathsf{\implies \frac{Decrease\;in\;Price\;of\;Laptop\;from\;2009\;to\;2010}{Price\;of\;Laptop\;in\;2009} \times 100}[/tex]

[tex]\mathsf{\implies \frac{165}{1100} \times 100}[/tex]

[tex]\mathsf{\implies 15\%}[/tex]

The percent decrease in laptop prices, use the formula ((Original Price - New Price) / Original Price) x 100%. The percent decrease from 2007 to 2009 is 12%, and from 2009 to 2010 is 15% with a $165 decrease.

The cost of a laptop computer in 2007 was $1,250. In 2009, the price decreased to $1,100.

A.) To find the percent decrease from 2007 to 2009, you use the formula: Percent decrease = ((Original Price - New Price) / Original Price) x 100%

Substitute the values: ((1250 - 1100) / 1250) x 100% = 12%

Therefore, the percent decrease in the price of the laptop from 2007 to 2009 is 12%.

B.) To find the percent decrease from 2009 to 2010 with a $165 decrease, you apply the same formula: Percent decrease = ((Price in 2009 - Price in 2010) / Price in 2009) x 100%.

Substitute the values: ((1100 - (1100 - 165)) / 1100) x 100% = 15%

Therefore, the percent decrease in the price of the laptop from 2009 to 2010 is 15%.

Answer:

9×9×8×7×6= 27,216

Step-by-step explanation:

Your answer is :- 9×9×8×7×6= 27,216

Why did i multiply 9×9×8×7×6 ⤵️

Because we can fill each place of a five digit number with ten digits (0,1,2,3,4,5,6,7,8,9).

Now, let us assume the five digit number is abcde, where each alphabet represent a digit.

so according to our question a cannot be equal to 0 ( a≠0), because if a will be equal to zero then our number will be a four digit number. So a can be equal to 9 digits.

b digit can also be equal to 9 numbers. why??because we can place zero on the position of b and only one number will not be repeated which is a.

Now for c, d, e :- accordingly no number will be repeated so on the place of c, there can be 8 digits. On the place of d, there can be 7 digits. And on the place of e there can be 6 digits.

Therefore,

a×b×c×d×e=9×9×8×7×6=27,216

18. x = y = -3

21. y was substituted into the wrong equation. The solution is (x, y) = (2, 1).

18. Adding y to the first equation transforms it to ...

... x = y

Then you can substitute for either variable in the second equation.

... 2y -5y = 9 . . . . . substitute for x

... -3y = 9 . . . . . . . . simplify

... y = -3 . . . . . . . . . divide by the coefficient of y

.. x = -3 . . . . . . . . . x and y have the same value

___

21. The first equation is being used to find an expression for y in terms of x. If you substitute that expression back into the same equation, it will tell you nothing you didn't already know. (Here, it is telling you 5 = 5.) The expression is only useful if you substitute it into a different equation. Here, it needs to be substituted into the second equation:

... Step 2: 3x -2(-2x+5) = 4 ⇒ 7x -10 = 4 . . . . . substitute for y in the second eqn

... Step 3: 7x = 14 . . . . . add 10

... Step 4: x = 2 . . . . . . . divide by 7

... Step 5: y = -2·2 +5 = 1 . . . . . find the value of y from x using the expression from step 1. Now, you know the solution is (x, y) = (2, 1).

Final answer:

To find the height of the arch 50 ft. from the center, we can use the equation of a semi-ellipse. The height of the arch is approximately 31 ft. when rounded to the nearest foot.

Explanation:

To find the height of the arch 50 ft. from the center, we can use the equation of a semi-ellipse. The equation of a semi-ellipse with a length of a and a maximum height of b is given by: ((x^2)/(a^2))+((y^2)/(b^2)) = 1. In this case, the length of the bridge is 400 ft. and the maximum height is 100 ft., so we have: ((x^2)/(200^2))+((y^2)/(100^2)) = 1. To find the height when x = 50 ft., we substitute x = 50 into the equation and solve for y. Plugging in the values, we get: ((50^2)/(200^2))+((y^2)/(100^2)) = 1. Simplifying, we have: (2500/40000)+((y^2)/(100^2)) = 1.

Multiplying both sides by 40000 to get rid of the denominators, we have: 2500 + 400((y^2)/10000) = 40000. Simplifying further, we get: 2500 + 40(y^2) = 40000. Subtracting 2500 from both sides, we have: 40(y^2) = 37500. Dividing both sides by 40, we have: (y^2) = 937.5. Taking the square root of both sides, we have: y = 30.62. So, the height of the arch 50 ft. from the center is approximately 31 ft. when rounded to the nearest foot.
