1 answer:

6 0

If the point is on the unit circle:
x² + (√3/3 )² = 1²
x² + 3/9 = 1
x² + 1/3 = 1
x² = 1 - 1/3
x² = 2/3 / √
x = √2/√3 · √3/√3 = √6 / 3
Answer: A ) square root (6) / 3

What is the surface area of the triangular prism shown?

Luba_88 [7]

Answer:

Step-by-step explanation:

we need to find the surface area of the shapes before adding them together. the triangles are 6*4 and since there are two, we do not need to divide by 2. (normally to find the area of a triangle it is base times height divided by 2)

so the area of the triangles are 24 units. Next we have the outer rectangles. 7*5=35. Since there are 2, we multiply by 2. Last we have the middle rectangle. 7*6=42.

the whole equation would be: 24+70+42= 136

so your answer would be B: 136.

hope this helps :)

Find the slope of the line<br> (2,3) (13,8)

alexandr1967 [171]

Answer:

$\boxed{m=\frac{5}{11}}$

Step-by-step explanation:

$\left(2,\:3\right)\:\left(13,\:8\right)$

$\mathrm{Slope}=\cfrac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(2,\:3\right)$

$\left(x_2,\:y_2\right)=\left(13,\:8\right)$

$Slope(m)=\frac{8-3}{13-2}$

$m=\frac{5}{11}$

Hexagon DEFGHI is translated on the coordinate plane below to create hexagon D'E'F’G’H’I’

frez [133]

Answer:

The answer is " $\bold{(x,y)\longrightarrow (x-8, y-7)}$ ".

Step-by-step explanation:

In the given question some data is missing. so, the correct answer to this can be explained in the following example:

In the given example, point D is also known as the coordinates in the (2, 5), and in the coordination of the D prime (D') and after translation its co-ordinates value is (-6, -2). Since the very first choice is only accurate as:

⇒2-8 = -6

⇒ 5-7 = -2

It can try certain things too and see why this alone is the correct translation.
