In order to survive, organisms must maintain stable conditions in their bodies, even though their external environments are always changing.

For example, humans need to maintain an internal temperature around 37°C. Blood needs to have a pH around 7.4 and an oxygen saturation close to 100%.

What needs to happen in order to maintain these conditions?

A) Organ systems must interact with one another.
B) Organisms must be at rest.
C) Genes must be altered each time cells replicate.
D) All of these.

Answers

Answer 1

For humans (and other organisms) to maintain a constant internal temperature, pH, etc., we have to maintain homeostasis. The way our bodies maintain homeostasis is through our organ systems; they carry out processes which ensure we remain the same. Their interaction is vital to this process.

Answer:
A) Organ systems must interact with one another.

Answer 2

Organ systems must interact with one another.

Jerome went on a hike. He climbed three-fourths of a mile in two-thirds of an hour. What was his hiking speed in miles per hour?

Answers

You could do this with fractions. I'll do decimals later.

d = 3/4 mile
t = 2/3 hour
r = ????

r = 3/4 // 2/3 Invert and multiply the denominator
r = 3/4 * 3/2 = 9/8 = 1 1/8

If your calculator handles fractions, you can use it to do this. If not you can change this to a decimal.
d = 3/4 = 0.75 miles
t = 2/3 hour = 0.666666666 hours.
r = ???

d = r*t
r = d/t
r = 0.75 / 0.66666667
r = 1.125 miles / hour
which gives you exactly the same answer 1.125 = 1 1/8

Final answer:

Jerome's hiking speed was calculated by dividing the distance he hiked, three-fourths of a mile, by the time it took him, two-thirds of an hour. This yielded a hiking speed of 1.125 miles per hour.

Explanation:

To calculate Jerome's hiking speed in miles per hour, we need to divide the distance he hiked by the time it took him. Jerome hiked three-fourths of a mile in two-thirds of an hour. To find the speed, we use the formula:

Speed = Distance ÷ Time

Speed = ¾ mile ÷ ⅓ hour

To divide fractions, we multiply by the reciprocal of the denominator:

Speed = ¾ × ⅔ = 3/4 × 3/2 = 9/8

This fraction simplifies to 1⅛ (1.125) miles per hour. So, Jerome's hiking speed was 1.125 miles per hour.

It is important to remember that when we talk about speed, we are referring to the distance traveled over a certain period of time regardless of the direction of travel.

now, before continuing on the first root, recall that the sine has a range of -1 ⩽ sin(θ) ⩽1, however 5/3 is greater than 1, and therefore is out of range, meaning, there's no such angle, so we've got zilch there.

now, let's check the second root,

[tex]\bf sin(\theta )+7=0\implies sin(\theta )=-7\implies \measuredangle \theta =sin^{-1}(-7)[/tex]

well, hell -7 is smaller than -1, so is also outside the range for sine, and so, the second root gave also zilch, so, in short, there's no such angle.

The height of a rock thrown off a cliff can be modeled by h=-16t^2-8t+120, where h is the height in feet and t is time in seconds. How long does it take the rock to reach the ground?

Answers

The rock hits the ground after 4 seconds.

----------------------
Here is the work in how you can find this answer...:
----------------------

The height, h, of an object thrown upward from an initial height, H, with an initial velocity, Vo, is given by the function h as a function of time, t:

h(t) = -16t^2 + Vot + H

Since Vo = 48 ft/sec and H 64 ft, then:

h(t) = -16t^2 + 48t + 64

You want to know at what time, t, will the rock hit the ground (h = 0). Set the above function = 0.

-16t^2 + 48t + 64 = 0

Solve this quadratic equation for t. First, factor -16.

-16 ( t^2 - 3t -4 ) = 0

Apply the zero products principle.

t^2 - 3t - 4 = 0

Factor.

( t - 4 )( t + 1 )

Again, apply the zero products principle.

t - 4 = 0 and/or t + 1 = 0

If t - 4 = 0, then t = 4 seconds

If t + 1 = 0, then t = -1 second...Discard this solution as negative time is not meaningful in this problem.

A box has dimensions of 3 inches, 5 inches and 7 inches what is the surface area

Answers

Formula: 2(l*b+b*h+h*l)
2(3*5+5*7+7*3)
2(15+35+21)
2(71)
SA= 142

Final answer:

The surface area of a box with dimensions of 3 inches by 5 inches by 7 inches is calculated using the formula 2lw + 2lh + 2wh, resulting in a total surface area of 142 square inches.

Explanation:

To calculate the surface area of a box with dimensions of 3 inches, 5 inches, and 7 inches, you would use the surface area formula for a rectangular prism. The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height of the prism.

In this case:

Length (l) = 3 inches

Width (w) = 5 inches

Height (h) = 7 inches

Now, plug these dimensions into the formula:

Surface Area = 2(3 inches × 5 inches) + 2(3 inches × 7 inches) + 2(5 inches × 7 inches)

Surface Area = 2(15) + 2(21) + 2(35)

Surface Area = 30 + 42 + 70

Surface Area = 142 square inches

Therefore, the surface area of a box with dimensions of 3 inches by 5 inches by 7 inches is 142 square inches.

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. a pollster contacts 92 people in the 18-21 age bracket and finds that 78 of them respond and 14 refuse to respond. when 284 people in the 22-29 age bracket are contacted, 265 respond and 19 refuse to respond. assume that 1 of the 376 people is randomly selected. find the probability of getting someone in the 22-29 age bracket or someone who refused to respond.

Answers

probability = (total 22-29 age bracket + number of not respond and aged 18- 21) / total people
= (284+14) / 376
= 0.792
= 0.79

Final answer:

The probability of selecting a person from the 22-29 age bracket or someone who refused to respond is approximately 79.3% out of the total number of people contacted.

Explanation:

The student is asking about finding the probability of selecting either a person from the 22-29 age bracket or someone who refused to respond from a combined group of people contacted in a survey. To solve this problem, we use the addition rule of probability. The total number of people is 376. The number of people who are in the 22-29 age bracket is 284, and the number of people who refused to respond is 14+19=33. However, this would include those who refused from the 22-29 bracket twice, so we subtract the 19 from the 22-29 age group who refused, leaving us with 33-19=14. Thus, the total number in either category is the sum of these, 284+14=298.

The probability (P) of picking someone from the 22-29 age bracket or someone who refused to respond is therefore calculated as:

P = Number in either category / Total number = 298 / 376 ≈ 0.793 or 79.3%

Use the empirical rule to solve the problem. ed's monthly phone bill is normally distributed with a mean of $65 and a standard deviation of $11. what percentage of his phone bills are more than $76?

Answers

By the empirical rule, 84% of the distribution is below one standard deviation above the mean.

16% of Ed's monthly phone bills are more than $76.

Answer:

16% of his phone bills are more than $76

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 65

Standard deviation = 11

What percentage of his phone bills are more than $76?

76 = 65 + 11

So 76 is one standard deviation above the mean.

By the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean. The other 100-68 = 32% are more than 1 standard deviation from the mean. Since the normal probability distribution is symmetric, 16% of them are more than 1 standard deviation below the mean and 16% are more than 1 standard deviation above the mean. So

16% of his phone bills are more than $76

Write the equation of the line that passes through (–2, 1) and is perpendicular to the line 3x – 2y = 5.

Answers

To make the perpendicular line, it is convenient to swap the x- and y-coefficients and negate one, then offset the x- and y- by the point value:
.. 2(x +2) +3(y -1) = 0

This equation can now be put into any desired form. Based on the given equation, it looks like you would like "standard form."
.. 2x +3y = -1

To find the equation of a line that is perpendicular to the line 3x - 2y = 5 and passes through the point (-2, 1), we determine that the slope of the perpendicular line must be -2/3. Using the point-slope form, the equation of the desired line is y = (-2/3)x - (1/3).

Finding the Equation of a Perpendicular Line

To write the equation of a line that is perpendicular to another line, you first need to determine the slope of the original line. The given equation, 3x - 2y = 5, can be rewritten in slope-intercept form (y = mx + b) by solving for y:
3x - 2y = 5
=> -2y = -3x + 5
=> y = (3/2)x - (5/2)
The slope (m) of this line is 3/2. Perpendicular lines have slopes that are negative reciprocals of each other. Thus, the slope of the line perpendicular to the original line is -2/3.

To find the equation of the line passing through the point (-2, 1) with this slope, use the point-slope form of the equation:
y - y1 = m(x - x1)
=> y - 1 = (-2/3)(x + 2)
Simplifying, we have:

y - 1 = (-2/3)x - (4/3)
=> y = (-2/3)x - (4/3) + 1
=> y = (-2/3)x -(1/3)

This is the equation of the line that passes through (-2, 1) and is perpendicular to the line 3x - 2y = 5.

The original question I assume was:

We'll use the formula for the arc length of a function which is the following:
[tex]L=\int ds\\ ds=\sqrt{1+\lef(\frac{dx}{dy} )^2}dy[/tex]
Now let's get the derivative of x:
[tex]\frac{dx}{dy}=\frac{4}{8}y^3-\frac{2}{4}\frac{1}{y^{3}}\\=\frac{1}{2}(y^3-\frac{1}{y^3})[/tex]
Alright now plug this into ds formula to get:
[tex]ds=\sqrt{1+\frac{1}{4}(y^3-\frac{1}{y^3})^2}[/tex]

Now the integral will be more simple:
[tex]L=\int_1^2\sqrt{(\frac{1}{2}y^3+\frac{1}{2}y^{-3})^2}dy=\int_1^2\frac{1}{2}y^3+\frac{1}{2}y^{-3}dy\\=[\frac{1}{8}y^4-\frac{1}{4}y^{-2}]_2^1\\ =\frac{33}{16}[/tex]

Final answer:

The exact length of the curve x = y^48 + 14y^2, for 1 ≤ y ≤ 2, can be found by differentiating x with respect to y, substituting into the formula for arc length, and solving the integral from y=1 to y=2.

Explanation:

To solve this problem, we use the formula for the arc length of a curve given by a function in parametric form. This formula is L = ∫sqrt(1+(dx/dy)^2)dy, with integration done over the interval [1,2].

In this case, our function is given as x = y^48 + 14y^2. First, we differentiate x with respect to y to get dx/dy = 48y^47 + 28y. We then substitute this into the formula to get L = ∫sqrt(1+(48y^47 + 28y)^2)dy. To solve this integral, you can use a standard calculus method or a calculator with integral functions.

If the cubic function P(x) includes the points (−4, 0), (0, 0), and (2, 0), which of the following represents this function?

Answers

Final answer:

The function cannot be determined with the given information.

Explanation:

The given points (-4, 0), (0, 0), and (2, 0) indicate that the function is a cubic function with three real roots. A cubic function is of the form P(x) = ax^3 + bx^2 + cx + d. Since the function passes through the x-axis at (-4, 0), (0, 0), and (2, 0), the roots of the cubic function are -4, 0, and 2. Therefore, the function can be written as P(x) = a(x + 4)(x - 0)(x - 2). However, since a cubic function with three real roots has an odd degree, the coefficient 'a' must be negative or positive. This means that the function can also be written as P(x) = -a(x + 4)(x - 0)(x - 2) or P(x) = a(x + 4)(x - 0)(x - 2). So, the correct representation of the function cannot be determined with the given information.

F(x)= 1. 3[tex]\sqrt {-(x-2)+6}[/tex] =[tex]3\sqrt {-x+2+6}=3\sqrt{-x+8}[/tex] when (x-2≥0→x≥2) ⇒[ Piecewise function]

2. [tex]3\sqrt{-[-(x-2)]+6}=3\sqrt{x-2+6}=3\sqrt{x+4}[/tex] when [ x-2<0→x<2]⇒[ Piecewise function]

We see there is a shape which is is in the form of dome,point of intersection of two curves being (2,7.348), symmetrical on both side of line x=2.
