Answer:
If there are 52 ounces of cereal in 2 boxes, how many ounces are there in 5 boxes?
Step-by-step explanation:
If we have 52 ounces in 2 boxes, in 1 box we have: 52/2 = 26 ounces.
If we have 5 boxes and 26 ounces in each, we have: 5 x 26 = 130 ounces in total.

For a fixed amount of gas at a constant temperature, the volume of the gas is inversely proportional to its pressure. The function v=18000/p relates the volume in cubic inches and pressure in pounds per square inch of a gas. What is the volume when the pressure is 900 pounds per square inch?
Answer:
Volume of the gas is 20 cubic inches.
Step-by-step explanation:
Inverse proportion: Let x and y be two quantities are said to be inverse proportion or inversely proportional if one quantity increases at the same rate the other decreases.
[tex]x \propto \frac{1}{y}[/tex] or
[tex]x = \frac{k}{y}[/tex] ⇒[tex]k =xy[/tex] where k is constant.
Since, it is given that the volume of gas is inversely propotional to its pressure.
Given the function:
[tex]v = \frac{18000}{p}[/tex] ......[1] ; where volume in cubic inches and pressure in pounds per square.
To find the volume in cubic inches.
The pressure (p) = 900 pounds per square inch.
Substitute the value of p in [1];
[tex]v = \frac{18000}{900}= 20 in^3[/tex]
Therefore, the volume(v) = 20 cubic inches when the pressure is 900 pounds per square inch.
The volume when the pressure is 900 pounds per square inch is [tex]20 in^3.[/tex]
What is proportionality?proportionality can be explained as equality between two ratios, it gives relationship that is always in the same ratio.
We were given the function as[tex]v= \frac{18000}{p}[/tex]
But the pressure is given as pressure (p) = 900 pounds per square inch.
We can get volume, if we substitute "p" as;
[tex]v=\frac{18000}{p}[/tex]
[tex]V= \frac{18000}{900} =20 in^3.[/tex]
Hence, the volume when the pressure is 900 pounds per square inch is [tex]20 in^3.[/tex]

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule. A(n) = –3 + (n – 1)(–2.2)
The arithmetic sequence A(n) = –3 + (n – 1)(–2.2) yields the first, fourth, and tenth terms as -3, -9.6, and -22.8 respectively when n is substituted with the corresponding term number.
Explanation:The arithmetic sequence described by the rule A(n) = –3 + (n – 1)(–2.2) can be used to find specific terms of the sequence. To find the first term, plug in n = 1 into the formula to get A(1) = -3 + (1 - 1)(-2.2) = -3. The fourth term can be found by plugging in n = 4 which yields A(4) = -3 + (4 - 1)(-2.2) = -9.6. The tenth term is calculated as A(10) = -3 + (10 - 1)(-2.2) = -22.8. Therefore, the first, fourth, and tenth terms are -3, -9.6, and -22.8 respectively.

The curve y = x/(1 + x2) is called a serpentine. find an equation of the tangent line to this curve at the point (2, 0.40). (round the slope and y-intercept to two decimal places.) y =
The equation of the tangent line to the curve y = x/(1 + x2) at the point (2, 0.40) is given by y = -0.24x + 0.88, rounded to two decimal places.
Explanation:The subject of the question refers to calculus, specifically the concept of finding the equation of a tangent line to a curve. This process typically involves finding the derivative of the function (which gives the slope of the tangent), and then using the point-slope form of the line equation.
The derivative of y = x/(1 + x2) can be found using the quotient rule for differentiation and is given by y' = (1 - x2)/(1 + x2)2. Evaluating this at x = 2 gives a slope of about -0.24 (rounded to two decimal places).
The equation of the line is usually written in the slope-intercept form, y = mx + b, where m represents the slope and b represents the y-intercept. Since we know that the line passes through the point (2, 0.40), we can substitute these values into the equation and solve for b. This yields a y-intercept of about 0.88 (rounded to two decimal places).
Therefore, the equation of the tangent line to the curve y = x/(1 + x2) at the point (2, 0.40) is approximately y = -0.24x + 0.88.
