Mathematics
1 answer:
katovenus [111]3 years ago
7 0

Answer:

B

Step-by-step explanation:

recall that any radical expression \sqrt{A} has real solutions only if A is not negative. (otherwise you will have imaginary solutions)

hence in this case we have

\sqrt{8x},

for real solutions, 8x must be ≥ 0,

since 8 is a positive number, x must be ≥ 0 (answer)

Find the distance between the points (-4, 10) and (-4, -8).
Evgen [1.6K]

Answer:

18 units

Step-by-step explanation:

(-4 , 10) and (-4, -8)

Distance = \sqrt{(x_{2}+x_{1})^{2}+(y_{2}-y_{1})^{2}}\\

              = \sqrt{(-4-[-4])^{2}+(-8-10)^{2}}\\\\= \sqrt{(-4+4)^{2}+(-18)^{2}}\\\\=\sqrt{0 + 324}\\\\=\sqrt{324}\\\\= 18

240×10^3

Then simplify:

2.4×10^5

To check the answer:

30×8×10³=

30×8000= 240000

A county has a goal to build 12,000 bus stop shelters in 48 months . If the county builds 215 bus shelters each month , will it
Leokris [45]

Answer:

No, it will not reach its goal.

Step-by-step explanation:

The main reason why it will not meet its goal is because if you do the math, 215 x 48 does not equal 12000, it equals 10320 which is just 1680 shelters low. Therefore, they will not meet their goal.
