Answer:

x = (√21)/2

Step-by-step explanation:

The sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. That means the middle-length side is (√3)/2 times the length of the longest side.

x = (√3)/2·√7

$\boxed{x=\dfrac{\sqrt{21}}{2}}$

If the original function () = 22 − 1 is shifted to the left 3 units to make the

Rom4ik [11]

A horizontal translation is expressed by transforming

$f(x)\mapsto f(x+k)$

If $k$ is positive, the function is translated to the left. If $k$ is negative, the function is translated to the right.

So, a 3-units left shift is given by $k=3$ . So you have

$f(x)=2x^2-1 \implies f(x+3)=2(x+3)^2-1$

Answer:

Step-by-step explanation:

you find area of a triangle with equation:

$\frac{1}{2} bh$

base: 6

height: 8

$\frac{1}{2} (6)(8)$

$\frac{1}{2} (48)$

area equals: 24

vertex would be at (1,-8)

this is because each vertex is in a different quadrant so you would need a negative y axis to form the rectangle

Two lines intersect to form a linear pair with equal measures. One angle has the measure 9x° and the other angle has the measure

VARVARA [1.3K]

My understanding is that the 2 angles add up to 180 degrees, so 9x+9y-54=180. Also, 9x=90 and 9y-54=90. 9x=90, so x=10. 9y=90+54. 9y=144. y=16.
