HELP ASAP!!! Characterize the slope of the line in the graph. A. Zero B. Undefined C. Positive D. Negative
Alexxandr [17]

Answer:

Undefined

Explanation:

When a line is vertical like that, the slope is undefined. If it was horizontal, then it would be zero. Positive slopes go in an upward right direction. Negative slopes go in a downward left direction.

Find the distance between the points (-1,-9) and (1,-4)
Snezhnost [94]

The distance between the two points is 5.4

Explanation:

The points are (-1,-9) and (1,-4)

The distance between the two points can be determined using the formula

d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}

Substituting the values in the formula, we get,

d=\sqrt{(1+1)^{2}+(-4+9)^{2}}

Adding the values,

d=\sqrt{2^{2}+5^{2}}

Squaring the terms, we get,

d=\sqrt{4+25}

Simplifying, we have,

d=\sqrt{29}=5.4

Thus, the distance between the two points is 5.4

Which pipe configuration can deliver more water to
Stels [109]

Answer: One 8-cm pipe (Its is greater than the total area of of two 4-cm pipes)

Step-by-step explanation:

The area of a circle can be calculate with this formula:

A=\pi r^2

Where "r" is the radius of the circle.

We need to calculate the area of 8-cm pipe. In this case:

r=8cm

Then, substituting the radius into the formula, we get:

A=\pi (8cm)^2\\\\A=201.06cm^2

Now we must calculate the area of the two 4-cm pipes.

Since they are two pipes, the formula is:

A=2\pi r^2

In this case:

r=4cm

Then, substituting into the formula, we get:

A=2\pi (4cm)^2\\\\A=100.53cm^2

Therefore, since the area of one 8-cm pipe is greater than the total area of of two 4-cm pipes, we conclude that the pipe configuration that can deliver more water to residents is:

One 8-cm pipe

A truck driver is driving from Nome, Alaska to Death Valley, California. Because he is traveling between locations with extreme
Yanka [14]

Answer:

Part A: The temperature must be greater than -40, and lower than 140.  -40 < T < 140

Part B: The graph is a number line between -40 and 140, with open circles at -40 and 140.  The solutions are temperatures at which the gas will remain liquid.

Part C: No, -49 is less than -40, so the gas would have frozen.

Hoped it helped:)
