8^2 + x^2 = 10^2
64 + x^2 = 100
x^2 = 36
x = 6

Answer:
j(x) is shifted right by units
Step-by-step explanation:
Given
Required
Determine the transformation from j(x) to k(x)
The transformation shows a horizontal shift from j(x) to k(x).
First, we need to determine the unit shifter from j(x) to k(x) as follows;
Express as
So:
becomes
Reorder
Comparing this to k(x), we have:
In other words:
<em>This implies that j(x) is shifted right by </em><em> units</em>
Answer: she paid $1.71 in sales tax.
Step-by-step explanation:
Find 9 percent of 19 to find the sale tax.
9% of 19 =
0.09 * 19 = 1.71
This means she paid $1.71 in sales tax.

Answer:
yes
Step-by-step explanation:
The tower is about 50.1 meters tall. The guidebook is correct.
__
The distance from the base of the tower to the angle vertex is ...
d1 = h/tan(46°)
d2 = d1 +50 = h/tan(27°)
Then the height of the tower is ...
h/tan(46°) +50 = h/tan(27°)
50 = h(cot(27°) - cot(46°))
h = 50/(cot(27°) -cot(46°)) ≈ 50/(1.96261 -0.96569) ≈ 50/0.99692
h ≈ 50.1544 . . . meters
The tower is more than 50 meters high.
