A plane is a flat surface that extends infinitely in all directions; thus, a lot of points can be found on a given plane. The plane can be named by taking any three points on it, in no specific order, as long as these points are not on a straight line. An example is plane ABC, given that points A, B and C are found on the plane and are not collinear.

The depth of a scuba diver can be modeled by the equation d 0.5t (3.5t- 28.25), where d is the depth in meters of the diver and

user100 [1]

We know that

using a graph tool
see the attached figure

The diver reaches the surface when d = 0
so
0.5t (3.5t- 28.25)=0---------> the solution is
0.5t=0--------> t=0
and
(3.5t- 28.25)=0----------> 3.5t=28.25--------> t=28.25/3.5--------> t=8.07 minutes


the time it takes for the diver to reach the surface is when the depth is zero
the time is 8 minutes

the answer is
8 minutes

The volume of a prism is 45 km3. What would change if the volume of the prism were measured in cubic meters?

givi [52]

The volume of the prism stays the same, but the number representing the volume increases because cubic meters converted to km is 1e-9

A hot air balloon in flight begins to ascend at a steady rate of 120 feet per minute. After 1.5 minutes, the balloon is at an al

azamat

Answer:

The balloon will not reach 2,500 feet after 4 minutes.

Step-by-step explanation:

The equation of the line in the point-slope form is

$y-y_1=m(x-x_1)$

A hot air balloon in flight begins to ascend at a steady rate of 120 feet per minute, then the slope is

$m=120$

After $x_1=1.5$ minutes, the balloon is at an altitude of $y_1=2,150$ feet. This means, the line passes through the point (1.5, 2,150).

Substitute the slope and point coordinates into the equation:

$y-2,150=120(x-1.5)$

We know that after 3 minutes, the balloon is at an altitude of 2,330 feet. Check this:

$2,330-2,150=180\\ \\120(3-1.5)=120\cdot 1.5=180\\ \\2,330-2,150=120(3-1.5)$

Now, find the height after 4 minutes:

$y-2,150=120(4-1.5)\\ \\y=120\cdot 2.5+2,150=300+2,150=2,450$

Thus, the balloon will reach only 2,450 feet after 4 minutes.

Consider parallelogram WXYZ, where diagonal WY and XZ intersect at point Q. If WQ =8 and ZX = 20, which statement is true?

Alina [70]

Answer:

C) YQ = 8

Step-by-step explanation:

If WQ is 8 and XZ bisects this line, this means that YQ is also 8.

The last answer: 2 or 0

Explanation:

When you graph this function, it crosses the x-axis once. In other words, that means there is only 1 real zero and 2 imaginary complex zeros. In addition, imaginary solutions always come in pairs, so there can’t be a odd number of them such as 3.
