at this rate how much blood would your heart pump in one hour? show your calculation.

Answers

Answer 1
The heart beat rate is 70beats/minute with 80ml of blood pumped every beat. Then, the volume of blood your heart pumps in one minute would be:

volume of blood per minute= volume per beat * beat per minute
volume of blood per minute= 80ml/beat * 70beat/minute= 560ml/ minute

volume of blood per hour would be: 560ml/minute * 60 minute/hour= 33.600 ml/hour

if the height of a rectangular prism is doubled then the surface area of the prism is and I need work to PLEASE HELP ME

Answers

The surface area of a rectangular prism (S) is given in terms of length L, width W, and height H by
.. S = 2(LW +H(L +W))

If you double the height, now you have new surface area S'
.. S' = 2(LW +2H(L +W)) = 2(LW +H(L +W)) +2H(L +W)

pete's pools installs rectangular pools that are all 10 feet wide. the length can vary from 10 feet to 30 feet. the company installed a pool with a perimeter of 76 feet. what was the length of the pool ?

Answers

the length is 28 because 76 -10x2 is 56 divided by 2 is 28

The length of pool is 28 feet.

What is perimeter?

The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.

Given rectangular pool

width of pool is 10 feet,

and length is between 10 to 30 feet

perimeter of pool = 76 feet

perimeter  = p = 2(l + b)

where l = length and b = breadth/width

76 = 2(l + 10)

l + 10 = 38

l = 38 - 10

l = 28 feet

Hence length of pool is 28 feet.

Solve the inequalities by graphing. Select the correct graph. y > x y < -x

Answers

my answer is x y because as the simulation show here y>x y <-× and because we are taking a way the x in this problem here I am assuming that the yas well have to be taking out as well for for the fact that is one we are subtracting from the x so we stay with x y it show you in the example y> / yx /<-x

The solution to the system of inequalities y > x and y < -x is a V-shaped region in the second and fourth quadrants of the coordinate plane.

Graph attached.

To solve the system of inequalities graphically, you need to shade the regions on the coordinate plane that satisfy both inequalities.

The first inequality is y > x. This means that all points above the line y = x satisfy this inequality.

The second inequality is y < -x. This means that all points below the line y = -x satisfy this inequality.

Now, let's graph both lines and shade the regions that satisfy both inequalities:

Graph the line y = x. This is a straight line with a slope of 1 that passes through the origin (0,0) and goes up and to the right.

Graph the line y = -x. This is also a straight line with a slope of -1 that passes through the origin (0,0) and goes down and to the right.

Graph attached.

The shaded region that satisfies both inequalities is the area between these two lines, below y = -x, and above y = x.

It forms a V-shaped region in the second and fourth quadrants of the coordinate plane.

Therefore, the correct graph should show the shaded V-shaped region that represents the solution to the system of inequalities.

How do you write 5.82 × 10^3 in standard form?

Answers

5.82 × 10^3

Because of the 10 to the power of 3, you are able to move the decimal point to get to standard form.

If the exponent is positive, move the decimal point to the right. If it's negative, move it the left.

Here, the 3 is positive, so we'll be moving the decimal in 5.82 three times to the right.

One space to the right would change it to be 58.2 * 10^2.
Two spaces would be 582 * 10.
Three spaces would be 5820.

The standard form of 5.82 × 10^3 is 5820.

How long will it take for 2 g of a sample of iodine-131, which has a half-life of about 8 days, to decay to 0.04 g?

Answers

we know that

This problem can be represented through the following equation

A = A₀(1/2)^t/h
where
A----------->  is the amount of substance left after time t
A₀ ----------> is the original amount---------> 2 g
h------------->  is the half-life-----------> 8 days

for A=0.04 g
t=?
0.04 = 2(1/2)^t/8
0.02 = (1/2)^t/8
Take ln on both sides:
ln(0.02) = ln [(1/2)^t/8]

Find the distance from the point to the given plane. (1, −7, 8), 3x + 2y + 6z = 5

Answers

Final answer:

To find the distance from the point (1, -7, 8) to the plane 3x + 2y + 6z = 5, we use the formula for the distance of a point from a plane, resulting in a distance of 32/7 units.

Explanation:

The question deals with finding the distance from a point to a given plane. Specifically, it asks for the distance from the point (1, −7, 8) to the plane defined by the equation 3x + 2y + 6z = 5. To solve this, we use the formula for the distance of a point (x1, y1, z1) from a plane ax + by + cz = d:

D = |ax1 + by1 + cz1 − d| / √(a2 + b2 + c2)

Substituting the given values, we get:

D = |3(1) + 2(−7) + 6(8) − 5| / √(32 + 22 + 62)

This simplifies to:

D = |3 − 14 + 48 − 5| / √(9 + 4 + 36)

D = |32| / √49

D = 32 / 7

Therefore, the perpendicular distance from the point to the plane is 32/7 units.

Suppose you are climbing a hill whose shape is given by the equation z = 1400 − 0.005x2 − 0.01y2, where x, y, and z are measured in meters, and you are standing at a point with coordinates (100, 120, 1206). the positive x-axis points east and the positive y-axis points north. (a) if you walk due south, will you start to ascend or descend?

Answers

Answer: You start to ascend

Explanation:

Since you are walking due south and the positive y-axis points north, the y-coordinate decreases.

Let 

[tex]y'[/tex] = y-coordinate after walking due south
[tex]z'[/tex] = z-coordinate (or the height) after walking due south

So, the point where you stand after walking due south has a coordinate of [tex](100, y', z')[/tex]. Moreover,

[tex]z' = 1,400 - 0.05(100)^2 - 0.01(y')^2 \\ \boxed{z' = 1350 - 0.01(y')^2}[/tex]

Since the y-coordinate decreases after walking due south and [tex]z' = 1350 - 0.01(y')^2[/tex],

[tex] y' \leq 120\\ \Rightarrow (y')^2 \leq 120^2 = 14,400\\ \Rightarrow -0.01(y')^2 \geq -0.01(14,400) = -144\\ \Rightarrow z' = 1,350 - 0.01(y')^2 \geq 1,350 - 0.01(14,400) = 1,206\\ \Rightarrow \boxed{z' \geq 1,206}[/tex]

So, the height after walking due south exceeds 1,206 meters, which is the previous height before walking due south. Therefore, if you walk due south from point with coordinates (100, 120, 1206), you are ascending.

If walking due south from the point (100, 120, 1206) will cause you to descend, as the slope of the hill in the southward direction is negative.

To determine whether you will ascend or descend when walking due south from the point (100, 120, 1206), we need to consider the slope of the hill in the southward direction, which corresponds to the negative y-direction.

Given the equation of the hill's shape: [tex]\[ z = 1400 - 0.005x^2 - 0.01y^2 \][/tex]

We can find the slope in the y-direction (southward) by taking the partial derivative of z with respect to y:

[tex]\[ \frac{\partial z}{\partial y} = -2 \cdot 0.01 \cdot y \][/tex]

Evaluating this derivative at the point (100, 120, 1206) gives us the slope in the y-direction at that point:

[tex]\[ \frac{\partial z}{\partial y}\Bigg|_{(100, 120, 1206)} = -2 \cdot 0.01 \cdot 120 = -2.4 \][/tex]

Since the slope is negative, this means that as you move in the positive y-direction (northward), the height z decreases. Conversely, moving in the negative y-direction (southward) will also result in a decrease in height z, because the slope is linear and does not change direction.

Therefore, walking due south from the point (100, 120, 1206) will cause you to descend, as the slope of the hill in the southward direction is negative.

A football stadium holds 52,000 fans. A college student is doing research and determines that on any given game day, the home team has five times as many fans as the visiting team. In order to help the student in his research, he represents the number of home team tickets as H and the visiting team’s tickets as V.

Answers

You probably are interested in setting up system of equations to find the number of fans for Home Team and Visiting Team.

Based on this data, we can find the number of number of fans of each team.

Following data has been provided:

1) Total number of fans stadium can hold = 52000
So on a given day if stadium is full,
H + V = 52000

2) Home team has 5 times as many fans as the visiting team.
So,
H = 5V

Using the value of H in first equation, we get:

5V + V = 52000
6V = 52000
V = 8667 fans

H + V = 52000

H = 52000 - V = 52000 - 8667 = 43333 fans

So, 
there will be 43,333 fans of home team and 8667 fans of visiting team.

Point T' has coordinates (-3, 4). If it was translated up 3 units, what were the coordinates of its pre-image?

(0, 4)
(-3, 7)
(-3, 1)
(-6, 4)

Answers

Translation refers to a rigid motion or transformation where you move an object from one location to another. 
Translations are base on the rule (x,y) -- (x+a, y+b) where the words right and left represent the change in the x-axis, and the words up and down the change in the y-axis.

In this exercise it is asked you to find the coordinates of the preimage of point T', which has the coordinates (-3,4) and is the effect of a translation of 3 units up. As previous said, the words up and down represent a change on the y-axis, meaning that the y-coordinate is the one that should be changed.

If the translation from the preimage to the image was 3 units up, then the preimage can be found by subtracting three units.
Pre-image: (-3,4-3)= (-3,1)

The point that represents the coordinates of the pre-image is (-3,1).

Answer: the answer is (-3, 1)

hopes this helped

Final answer:

The midpoint formula calculates the center point between two points on a coordinate plane, while the distance formula calculates the distance between two points using the Pythagorean theorem.

Explanation:

Understanding the Midpoint and Distance Formulas

The midpoint formula is used to find the exact center point between two defined points on a coordinate plane. To find the midpoint (M) between two points, (X1, Y1) and (X2, Y2), you use the formula:

M = ((X1 + X2) / 2, (Y1 + Y2) / 2)

For example, to find the midpoint between the points (2, 3) and (4, 8), you would calculate:

M = ((2 + 4) / 2, (3 + 8) / 2) = (3, 5.5)

The midpoint between these points is at coordinates (3, 5.5).

The distance formula, on the other hand, is used to determine the distance between two points on a coordinate plane.

The formula is derived from the Pythagorean theorem and is written as:

D = \(√((X2 - X1)^2 + (Y2 - Y1)^2)\)

Using the above points, the distance (D) would be:

D = \(√((4 - 2)^2 + (8 - 3)^2)√ = \(√(4+25) = \(√29\)√

The distance between the two points is the square root of 29.

Practicing these formulas enhances your problem-solving skills and helps in many areas of mathematics, including geometry and algebra.
