This is an example of a distribution property. In a distribution property, the number outside the parenthesis is distributed to all the terms inside it by multiplication. So the answer here is:

Find ST if S(-3,10) and T(-2,3)
Aleonysh [2.5K]

Answer:

ST = 7.07 units

Step-by-step explanation:

* Lets explain how to find the length of a segment

- The length of a segment whose endpoints are (x_{1},y_{1})

  and (x_{2},y_{2}) can be founded by the rule of the distance

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

* Lets solve the problem

∵ The line segment is ST

∵ S is (-3 , 10)

∵ T is (-2 , 3)

- Assume that S is (x_{1},y_{1}) and T is (x_{2},y_{2})

∴ x_{1}=-3 and x_{2}=-2

∴ y_{1}=10 and y_{2}=3

- By using the rule above

∴ ST=\sqrt{(-2--3)^{2}+(3-10)^{2}}

∴ ST=\sqrt{(1)^{2}+(-7)^{2}}

∴ ST=\sqrt{1+49}

∴ ST=\sqrt{50}

∴ ST = 7.07 units

The height, h, in feet of the tip of the hour hand of a wall clock varies from 9 feet to 10 feet. Which of the following equatio
Mama L [17]
We can tell from the data that there is a midpoint between the lowest and highest point of the clock, which is at a height of 9.5 feet.
Moreover, the lowest point occurs at 6 o clock, and the highest occurs at 12 o clock.
The amplitude of variation from the mid-point is 0.5 feet given by (10 - 9) / 2.
Finally, the time period for the equation is 12 hours. Thus, the answer is:
h = 0.5cos(πt/6) + 9.5, option B

A man on a diet is losing four-tenths of a kilogram each day. How many days will it take him to lose 3.2 kilograms?
Alborosie

so he's losing 4/10 of a Kg daily, how many times will that equal 3.2 Kgs? namely how many times does 4/10 go into 3.2?

well, let's firstly convert 3.2 to a fraction, and then divide.

\bf \stackrel{\textit{1 decimal}}{3.\underline{2}}\implies \cfrac{32}{\underset{\textit{1 zero}}{1\underline{0}}}\implies \cfrac{16}{5} \\\\[-0.35em] ~\dotfill

\bf \cfrac{16}{5}\div \cfrac{4}{10}\implies \cfrac{16}{5}\div \cfrac{2}{5}\implies \cfrac{\stackrel{8}{~~\begin{matrix} 16 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}}{~~\begin{matrix} 5 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}\cdot \cfrac{~~\begin{matrix} 5 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}{~~\begin{matrix} 2 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}\implies 8

HELP PLEASE!! Based on the table, which best predicts the end behavior of the graph of f(x)?
adelina 88 [10]

Solution: The correct option is option D.

Explanation:

The end behavior is the behavior of function as the input of the function approaches to very large value and very small value.

If a function is f(x), then at x\rightarrow \infty and x\rightarrow -\infty  the value of f(x) approaches to either infinity or negative infinity which defines the end behavior.

From the given table it is noticed that the as x decreases and approaches to large negative values then the values of the function is also approaches to the large negative values. According to the table as x\rightarrow -\infty, f(x)\rightarrow -\infty.

From the given table it is noticed that the as x increases and approaches to large positive values then the values of the function is approaches to the large negative values. According to the table as x\rightarrow \infty, f(x)\rightarrow -\infty .

Since only option D satisfy the both conditions, therefore the correct option is option D.
