Which inequality is equivalent to 3+4/x>=x+2/x
Answer:
The first alternative is correct
Step-by-step explanation:
We move all the expressions to the left hand side of the inequality then combine like terms using lcm;
[tex]\frac{3}{1}+\frac{4}{x}-\frac{x+2}{x}\geq0\\\\\frac{3x+4-(x+2)}{x}\geq0\\\frac{2x+2}{x}\geq0[/tex]
Answer:
the first one
Step-by-step explanation:
Express the left side as a single fraction
3 + [tex]\frac{4}{x}[/tex]
= [tex]\frac{3x+4}{x}[/tex], hence
[tex]\frac{3x+4}{x}[/tex] ≥ [tex]\frac{x+2}{x}[/tex]
Subtract [tex]\frac{3x+4}{x}[/tex] from both sides
0 ≥ [tex]\frac{x+2}{x}[/tex] - [tex]\frac{3x+4}{x}[/tex]
0 ≥ [tex]\frac{-2x-2}{x}[/tex]
Multiply both sides by - 1, remembering to reverse the inequality symbol as a consequence
0 ≤ [tex]\frac{2x+2}{x}[/tex], hence
[tex]\frac{2x+2}{x}[/tex] ≥ 0

during a softball game kay hit a fly ball the function f(x) = -16t^2 + 64t + 4 describes the height of the softball in feet. make a table of values for the function and then graph it.
The graph is attached.
To graph a parabola we need to know the following:
- If the parabola is open upwards or downwards
- They axis intercepts (if they exist)
- The vertex position (point)
We are given the function:
[tex]f(t)=-16t^{2}+64t+4[/tex]
Where,
[tex]a=-16\\b=64\\c=4[/tex]
For this case, the coefficient of the quadratic term (a) is negative, it means that the parabola opens downwards.
Finding the axis interception points:
Making the function equal to 0, we can find the x-axis (t) intercepts, but since the equation is a function of the time, we will only consider the positive values, so:
[tex]f(t)=-16t^{2}+64t+4\\0=-16t^{2}+64t+4\\-16t^{2}+64t+4=0[/tex]
Using the quadratic equation:
[tex]\frac{-b+-\sqrt{b^{2}-4ac } }{2a}=\frac{-64+-\sqrt{64^{2}-4*-16*4} }{2*-16}\\\\\frac{-64+-\sqrt{64^{2}-4*-16*4} }{2*-16}=\frac{-64+-\sqrt{4096+256} }{-32}\\\\\frac{-64+-\sqrt{4096+256} }{-32}=\frac{-64+-(65.96) }{-32}\\\\t1=\frac{-64+(65.96) }{-32}=-0.06\\\\t2=\frac{-64-(65.96) }{-32}=4.0615[/tex]
So, at t=4.0615 the height of the softball will be 0.
Since we will work only with positive values of "x", since we are working with a function of time:
Let's start from "t" equals to 0 to "t" equals to 4.0615.
So, evaluating we have:
[tex]f(0)=-16(0)^{2}+64(0)+4=4\\\\f(1)=-16(1)^{2}+64(1)+4=52\\\\f(2)=-16(2)^{2}+64(2)+4=68\\\\f(3)=-16(3)^{2}+64(3)+4=52\\\\f(4.061)=-16(4.0615)^{2}+64(4.0615)+4=0.0034=0[/tex]
Finally, we can conclude that:
- The softball reach its maximum height at t equals to 2. (68 feet)
- The softball hits the ground at t equals to 4.0615 (0 feet)
- At t equals to 0, the height of the softball is equal to 4 feet.

The adult population of a town in 2000 was 400. The child population of the town in 2000 was 120. Both the adult and child populations increased by the same percent from 2000 to 2010. If the adult population in 2000 was 500, how many children lived in the town then?
Answer:
150
Step-by-step explanation:
500 is 125% of 400 (500/400) so you need to get what 125% of 120 is
120 x 1.25 =150
^number of children ^125% as a decimal
To find the number of children after the same percent increase in population as the adults, calculate a 25% increase based on the adult growth from 400 to 500. Applying this to the original child population (120), there were 150 children in 2010.
The question pertains to the percent increase in population and requires finding the number of children in a town given the increase in adult population. Specifically, the child population in 2000 was 120, and the adult population increased from 400 to 500 from 2000 to 2010. Assuming that the child population increased by the same percent as the adult population, we need to calculate this percentage increase and then apply it to the number of children to find the updated child population in 2010.
To find the percentage increase in the adult population:
Calculate the increase by subtracting the original number from the new number (500 - 400 = 100).Divide the increase by the original number (100 / 400 = 0.25).Convert the decimal to a percentage by multiplying by 100 (0.25 × 100 = 25%).Since the child population increased by the same percentage, we then:
Apply the 25% increase to the original child population (120).Multiply 120 by 0.25 to find the increase (120 × 0.25 = 30).Add the increase to the original child population (120 + 30 = 150).Therefore, there were 150 children in the town in 2010.

Mrs. Eskew saved her money for 37 years and had $2,119,784 in the bank. She used her money to go a vacation for a month and spent $278,389. How much did she have left after her vacation?
Mrs. Eskew will have $1,841,395 left after subtracting the vacation expense of $278,389 from her initial savings of $2,119,784.
The student is asking how much money Mrs. Eskew will have left after spending part of her savings on a vacation. To find out, we simply need to subtract the amount spent on the vacation from the total amount she had saved. Mrs. Eskew started with $2,119,784 in the bank. After spending $278,389 on her vacation, we can calculate her remaining balance as follows:
$2,119,784 - $278,389 = $1,841,395.
Therefore, Mrs. Eskew will have $1,841,395 left after her vacation.
what is the exact volume email of the cylinder
Answer:
A. V=BH
Step-by-step explanation:
The exact volume email of the cylinder in the image is 324π in³.
This is calculated using the formula for the volume of a cylinder:
Volume = πr²h
where:
π is a mathematical constant with the approximate value of 3.14
r is the radius of the cylinder
h is the height of the cylinder
In the image, the radius of the cylinder is 3 in and the height is 6 in. Therefore, the volume of the cylinder is:
Volume = π(3 in)²(6 in)
Volume = π(9 in²)(6 in)
Volume = 54π in³
However, the image also contains the text 324π in³.
This is the correct volume of the cylinder, as it takes into account the fact that the cylinder is hollow.
Therefore, the exact volume email of the cylinder in the image is 324π in³.

The width of a rectangle, in feet, is represented by (3x-1.5). The length of the rectangle, in feet, is represented by (1.25x+3). Find the perimeter of the rectangle.
Answer:
P = 8.5 x + 3 ft
Step-by-step explanation:
To find the perimeter, we use the formula
P =2(l+w) where l is the length and w is the width
P =2 (1.25x+3 + 3x-1.5)
Combine like terms
P = 2( 4.25x +1.5)
Distribute the 2
P = 8.5 x + 3 ft
The perimeter of the rectangle in terms of x is [tex]\( {\frac{17}{2}x + 3} \)[/tex].
Given the width of the rectangle is (3x - 1.5) feet and the length is (1.25x + 3) feet, we can substitute these expressions into the perimeter formula.
First, let's express the width and length in terms of xwith rational numbers to avoid dealing with decimals:
Width [tex]\( w = 3x - \frac{3}{2} \)[/tex]
Length [tex]\( l = \frac{5}{4}x + 3 \)[/tex]
Now, we can calculate the perimeter:
[tex]\( P = 2(l + w) \)\\ \( P = 2 \left( \left( \frac{5}{4}x + 3 \right) + (3x - \frac{3}{2}) \right) \)\\ \( P = 2 \left( \frac{5}{4}x + 3 + 3x - \frac{3}{2} \right) \)\\ \( P = 2 \left( \frac{5}{4}x + 3x + 3 - \frac{3}{2} \right) \)\\ \( P = 2 \left( \frac{5}{4}x + \frac{12}{4}x + \frac{6}{2} - \frac{3}{2} \right) \)\\ \( P = 2 \left( \frac{17}{4}x + \frac{3}{2} \right) \)\\ \( P = 2 \times \frac{17}{4}x + 2 \times \frac{3}{2} \)\\ \( P = \frac{34}{4}x + 3 \)\\ \( P = \frac{17}{2}x + 3 \)[/tex]
perimeter = [tex]\( {\frac{17}{2}x + 3} \)[/tex].

A company owns rental properties and must pay for repairs and upkeep. If the monthly maintenance costs have an average of $3500.00 and a standard deviation of $257.00, give the range of costs the company can count on having to pay about 95% of the time.
Given is - the monthly maintenance costs have an average of $3500 and a standard deviation of $257. This means that around 95% of the distributed data lies within the ranges of -257 to +257 of the given standard deviation.
Hence, range becomes :
[tex]3500-257=3243[/tex] and [tex]3500+257=3757[/tex]
Thus, the range is (3243 , 3757)
Answer:

Multiply (x^2+3x+4)(3x^2-2x+1)
Answer: option B
Step-by-step explanation:
To solve this exercise you must apply the proccedure shown below:
- Apply the Distributive property (Remember that when you multiply two powers with the same base, you must add the exponents).
[tex]b^m*b^n=b^{(m+n)}[/tex]
- Add the like terms.
Therefore, you obtain that the product is:
[tex](x^2+3x+4)(3x^2-2x+1)=3x^4-2x^3+x^2+9x^3-6x^2+3x+12x^2-8x+4\\=3x^4+7x^3+7x^2-5x+4[/tex]
Answer:
B
Step-by-step explanation:
When multiplying [tex](x^2+3x+4)(3x^2-2x+1)[/tex], we can use the distributive property of multiplication over addition:
[tex](x^2+3x+4)(3x^2-2x+1)=x^2\cdot 3x^2+x^2\cdot (-2x)+x^2\cdot 1+3x\cdot 3x^2+3x\cdot (-2x)+3x\cdot 1+4\cdot 3x^2+4\cdot (-2x)+4\cdot 1=3x^4-2x^3+x^2+9x^3-6x^2+3x+12x^2-8x+4.[/tex]
Now group the like terms:
[tex]3x^4-2x^3+x^2+9x^3-6x^2+3x+12x^2-8x+4=3x^4+(-2x^3+9x^3)+(x^2-6x^2+12x^2)+(3x-8x)+4=3x^4+7x^3+7x^2-5x+4.[/tex]

Answer:
y = 6x - 23Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points P(4, 1) and Q(3, -5). Substitute:
[tex]m=\dfrac{-5-1}{3-4}=\dfrac{-6}{-1}=6[/tex]
The refore we have the equation:
[tex]y=6x+b[/tex]
Put the coordinates of the point P(4, 1) to the equation:
[tex]1=6(4)+b[/tex]
[tex]1=24+b[/tex] subtract 24 from both sides
[tex]-23=b\to b=-23[/tex]
Finally we have the equation:
[tex]y=6x-23[/tex]

The solutions for the given problems involving factorials and permutations are 8! = 40,320, 5P5 = 120, 8P4 = 1,680, 7P7 = 5,040 and the number of arrangement for 4 performers out of 9 is 3,024.
Explanation:The subject here is mathematics, specifically factorials and permutations. Factorials are represented by the symbol '!'. The factorial of a number n is the product of all positive integers less than or equal to n. For example, 8! = 8*7*6*5*4*3*2*1 = 40,320.
Permutations refer to the number of ways a set of objects can be arranged. 'nPn' always equals to the factorial of n, therefore 5P5 equals to 5! = 5*4*3*2*1 = 120 and 7P7 equals to 7! = 7*6*5*4*3*2*1 = 5,040.
'nPm' equals to n factorial divided by (n-m) factorial. So, 8P4 equals to 8!/(8-4)! = (8*7*6*5)/1 = 1,680.
For the last question, the number of ways 4 performers can stand in a row out of 9, is calculated as a permutation of '9P4' (because the order of performers matters). Thus, it will be 9!/(9-4)! = 9*8*7*6 = 3,024.

Which inequality represents all possible solutions of -6n < -12?
The inequality -6n < -12 has all numbers greater than 2 as its solution after isolating 'n'. We achieve this by dividing both sides by -6 and flipping the inequality sign.
Explanation:To solve this inequality, -6n < -12, you first need to isolate 'n' on one side of the inequality. We do this by dividing both sides of the inequality by -6. It's important to remember that when we divide or multiply an inequality by a negative number, we need to flip the direction of the inequality sign. So, the inequality would become n > 2. This means that all numbers greater than 2 are the solutions of the inequality.
