Someone pleaseeee answer

Mathematics
1 answer:
svet-max [94.6K]2 years ago
4 0

Answer:

A

Step-by-step explanation:

We cannot take the square root of a negative number without using complex numbers. Because of this, both 5x and x+3 must be non-negative in order for the product to be defined.

  • 5x ≥ 0 implies that x ≥ 0
  • x + 3 ≥ 0 implies that x ≥ -3

Both of these are satisfied if and only if x ≥ 0 (note that if x ≥ 0, then x is automatically greater than or equal to -3). Therefore, the correct answer is x ≥ 0.

Please help this is so difficult
White raven [17]

Answer:

B

Step-by-step explanation:

For a line to be parallel it must have the same slope

6x-2y=-5

+5        +5

6x-2y+5 = 0

   +2y       +2y

6x+5  =2y

/2        /2

3x+5/2=y                  So the slope is 3 and we know it can only be either B or D

Now we need to find which line passes through (7,-2) and we find this by plugging 7 into B and D

B. -2= 21-23 TRUE

D. -2 = 21+ 23 FALSE

So the answer is B

How does the volume of an oblique cone change if the height is reduced to 2/3 of its original size and the radius is doubled
spayn [35]

The volume of oblique cone =\frac{1}{3} \pi r^{2} h

Now radius is doubled is now it is 2r

And height is reduced to 2/3 of its original size that is 2/3 h

So plugging the values we get volume

New Volume = \frac{1}{3} \pi (2r)^2 (\frac{2}{3} h)

= \frac{1}{3} \pi 4r^2 (\frac{2}{3} h) = \frac{8}{6} \pi r^{2} h =\frac{8}{2} (\frac{1}{3} \pi r^{2} h )=4*(\frac{1}{3} \pi r^{2} h )

It means the volume becomes 4 times
