The coordinates of point T are (0,4). the midpoint of ST is (7,-5). find the coordinates of point S
Nonamiya [84]

The formula of a midpoint:

M_{ST}\left(\dfrac{x_S+x_T}{2},\ \dfrac{y_S+y_T}{2}\right)

We have:

T(0,\ 4)\to x_T+0,\ y_T=4\\M(7,\ -5)\to x_M=7,\ y_M=-5

Substitute:

\dfrac{x_S+0}{2}=7\qquad|\cdot2\\\\x_S=14\\\\\dfrac{y_S+4}{2}=-5\qquad|\cdot2\\\\y_S+4=-10\qquad|-4\\\\y_S=-14

<h3>Answer: S(14, -14).</h3>

Ally's science class was looking at bacteria through a microscope. Ally's teacher said some bacteria can be as small as 0.00365
mamaluj [8]

The length of the bacteria should be written in scientific notation.

0.00365 in scientific notation = 3 × 10^-3

Given.

length of the bacteria in decimal = 0.00365 cm long

Scientific notation is written in the format x × 10ⁿ

where,

x = any number between digit 1 and 10

n = exponent (positive or negative).

  • To have a negative exponent value, move decimal to the right

  • To have a positive exponent value, move the decimal point to the left.

In this case, the nearest significant value is 3

So move the decimal point three times to where 3 is

That is,

0.00365 = 3.65

Since the decimal point is moved to the right 3 times, n = - 3

we have 10^-3

Therefore,

0.00365 in scientific notation = 3 × 10^-3

HELP! I NEED MORE THAN 5 SENTENCES!!
Ksenya-84 [330]

Answer:

I would assess what type of learner my student was by seeing which form of teaching they respond best to. I would try to cover all 7 types of learning by going through different examples. I would lead by explaining the concept and then start to work through at least 3 examples. I would then ask them to finish certain parts and eventually watch them work one out on their own. One of the key things I would make sure to do is personalize the learning experience. I would offer stories and situations that they may be able to relate to or remember when completing the problem.
