Which net matches the figure?

schepotkina [342]

In the first image, notice that the figure is a cube

also known as a "square prism."

Since a cube is composed of square bases, we

want to find a net that is composed of all squares.

Notice that the option of the bottom left is composed of squares.

So this net matches the figure.

How do i figure out these problems ?

Andreyy89

Given two vectors

$v=(a,b),\quad w=(c,d)$

they are parallel if they are a multiple of each other:

$c=ka,\quad d=kb$

You can easily test this by checking if

$\dfrac{c}{a}=\dfrac{d}{b}$

they are orthogonal if their dot product is null:

$v\cdot w=ac+bd=0$

For example, in the first case, we have

$\dfrac{10}{3}\div 2 \neq \dfrac{4}{3}\div 5$

So, they aren't parallel. Similarly, you have

$2\cdot \dfrac{10}{3}+5\cdot \dfrac{4}{3}\neq 0$

So, they aren't orthogonal.

In the second case, we have

$\dfrac{5}{-12}\neq \dfrac{-6}{-10}$

So, they aren't parallel, and

$5(-12)+(-6)(-10)=-60+60=0$

So, they are orthogonal.

Finally, we have

$\dfrac{2}{-4}=\dfrac{-7}{14}=-\dfrac{1}{2}$

So, they are parallel (and thus can't be orthogonal)

The number of views on an interesting video after it's uploaded is represented by the following table:

defon

Answer:

The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data is $,V(t)=50(6.25)^t$

Step-by-step explanation:

Time (months) Views

0 50

2 313

4 1950

6 12,210

8 76,300

10 476,800

$(x_1,y_1)=(0,50)\\(x_2,y_2)=(2,313)\\(x_3,y_3)=(4,1950)$

$Slope = \frac{y_2-y_1}{x_2-x_1}$

$Slope = \frac{313-50}{2-0}$

Slope =131.5

$Slope = \frac{y_3-y_2}{x_3-x_2}$

$Slope = \frac{1950-313}{4-2}$

Slope =818.5

Since the slope is not same . So, it is not a linear relationship

$\frac{y_2}{y_1}=\frac{313}{50}=6.25\\\frac{y_3}{y_2}=\frac{1950}{313}=6.25$

Since the ratio between the consecutive outputs is same so, it is exponential relationship.

Formula : $y=ab^t$

Where a is the initial value = 50

b = rate of change = 6.25

The model for V(t) ,the number of views, t ,months after it's uploaded, best fits the data

So $,V(t)=50(6.25)^t$
