Answer:

the answer is 5 BTUs/ft^3

Step-by-step explanation:

first: 10x15x10= 1500 ft ^3

second: 500 BTUs x 5 people= 2500 BTUs by all five people

third: 2500 BTUs x 3 hrs= 7500 BTUs per 3 hrs

lastly: divide 7500 BTUs by 1500 ft ^3 to get 5 BTUs/ ft^3

Find the distance between points P(3, 4) and Q(4, -6) If necessary round to the nearest hundredth.
Andrei [34K]

Answer:

10.05 units

Step-by-step explanation:

We can find the distance between these points using the distance formula. The distance formula is:

\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

We know that x1 is 3, x2 is 4, y1 is 4, and y2 is -6, so we can substitute inside the equation.

\sqrt{(4 - 3)^2 + (-6 - 4)^2} \\\\\sqrt{1^2 + -10^2} \\\\\sqrt{1 + 100} \\\\\sqrt{101} \\\\\approx10.05

Hope this helped!

Draw a line through the origin that has a slope of 4/3
Ket [755]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

In this problem the given line represent a proportional relationship, because passes through the origin

we have

k=\frac{4}{3} --->  the constant of proportionality k is equal to the slope

substitute

The linear equation is

y=\frac{4}{3}x

To draw a line we need two points

we have (0,0)

To find the other point

assume  x=3 and substitute in the equation to solve for y

y=\frac{4}{3}(3)=4

so

The other point is (3,4)

using a graphing tool

Plot the points (0,0) and (3,4)

To graph the line join the points

see the attached figure

What is csc ( Reduce fractional answers to lowest terms.
harina [27]

Answer:

cscA = \frac{5}{4}

Step-by-step explanation:

Using the identity

csc x = \frac{1}{sinx} , then

sinA = \frac{opposite}{hypotenuse} = \frac{BC}{AB} = \frac{8}{10} = \frac{4}{5} , thus

cscA = \frac{1}{\frac{4}{5} } = \frac{5}{4}
