x = 2, that is B(2) = - 1

From the coordinate diagram, the value of x ( x- axis ) corresponding to the value of y = -1 ( y- axis ) is x = 2

That is the point (2, - 1 )

Answer: The required value of x is 2.

Step-by-step explanation: We are given the graph of the function B(x) as shown in the figure.

We are to find the value of x such that B(x) = -1.

From the graph, we note that some points are plotted satisfying the function B(x) as follows :

(x, y= (-1, 1), (1, 2), (2, -1) and (3, 0), where y = B(x).

So, if y = B(x) = -1, then the corresponding value of x is 2.

Thus, the required value of x is 2.

Please help! what is the polar equation r = -5 theta in parametric form?<br><br> thank you!

Rudiy27

Use these equations when converting polar equations to parametric equations:

$x=r\cos\theta$

$y=r\sin\theta$

We know that $r=5\theta$ , so substitute that into both equations for x and y.

$x=5\theta\cos\theta$

$y=5\theta\sin\theta$

Now, replace $\theta$ with any variable that you want to represent the parametric equations in. I'll use the standard variable, $t$

$x=5t\cos t$

$y=5t\sin t$

Thus, $r=5\theta$ represented in parametric form is:

$(x,y)=(5t\cos t, 5t \sin t)$

Let me know if you need any clarifications, thanks!

Find the surface area of the right triangular prism shown

Inessa05 [86]

The surface area of the triangular prism is 144 cm²

<u>Explanation:</u>

Given:

Base of the triangle = 4

Height of the triangle = 3

Hypotenuse of the triangle = 5

Length of the prism = 11

Surface area of the rectangular prism = ?

Surface area, A = $ah+bh+ch+\frac{1}{2} \sqrt{-a^4 + 2(ab)^2 + 2(ac)^2 - b^4 + 2(bc)^2 - c^4}$

On substituting the value, we get:

$A = 4 X 11+ 3X11+5X11+\frac{1}{2} \sqrt{-(4)^2 + 2(4X3)^2 + 2(4X5)^2 - 3^4 + 2(3X5)^2-5^4} \\\\A = 144 cm^2$

Therefore, the surface area of the triangular prism is 144 cm²
