Answer:

V = π × r² × h

Step-by-step explanation:

All you need to do is multiply the base times the height and since the base is a circle whose formula is π × r², we get π × r² × h.

X2+5x=3x+11 and solve by completing the square

Butoxors [25]

$x^2+5x=3x+11\\
x^2+2x-11=0\\
x^2+2x+1-12=0\\
(x+1)^2=12\\
x+1=\sqrt{12} \vee x+1=-\sqrt{12}\\
x=-1+2\sqrt3 \vee x=-1-2\sqrt3$

Which parabola has the graph shown?

ryzh [129]

The vertex is (-1, 2).

The equation of parabola:

$x=(x-k)^2+h$ where (h, k) is the vertex

We have h = -1 and k = 2.

Substitute:

$x=(y-2)^2-1\ \ \ \ |+1\\\\(x+1)=(y-2)^2$

Rectangle J'K'L'M' shown on the grid is the image of rectangle JKLM after transformation. The same transformation will be applie

timama [110]

Answer:

(16, 7)

Step-by-step explanation:

Given rectangle JKLM

As per graph, the rectangle J'K'L'M' is the transformation of JKLM

Based on one of the points we can calculate the transformation rule:

Let's use points K and K'

K((-4, -8) → K'(6, -5)
6 - (-4) = 10
-5 - (-8) = 3

So the rule is

(x', y') → (x + 10, y +3)

Trapezoid STUV:

Using point T(6, 4)

Applying same rule:

T' = (6 + 10, 4 +3) = (16, 7)

Determine the missing side length

soldier1979 [14.2K]

Answer:

√85

Step-by-step explanation:

The given shape is a right angled triangle.

Let the missing side length be " x ".

By Pythagoras theorem,

x² = 6² + 7²

x² = 36 + 49

x² = 85

x = √85

Therefore, the missing side length be √85.
