The answer is 17

Explanation
XZ is the hypotenuse of the right angled triangle
so
XZ² = YZ² + YX²
XZ² = 15² + 8²
XZ² = 289
XZ = √289 = 17

Answer:

17 cm

Step-by-step explanation:

Because if you use the Pythagorean threom a^2 + b^2 = c^2. 8 squared is 64 and 15 squared is 225 add those and you get 289, and 17 squared is 289.

Step-by-step explanation:

Here's your worksheet with the blanks filled.

Of course, you know these log relations:

log(a^b) = b·log(a) . . . . . power property

log(a/b) = log(a) -log(b) . . . . . quotient property

log(x) = log(y) ⇔ x = y . . . . . . . . . equality property

Amber is starting a garden. She plants 2 flowers the first month. The next month, she plans three times more flowers (6 flowers)

Artist 52 [7]

This is a geometric progression problem. We can the general formula that can tell us how many flowers would be planted each month.
Let's write the terms that we know and see if we can find the pattern:
$
\begin{tabular}{lll}
Month & Number of flowers planted & Different form \\
1 & 2 & 2\cdot3^0 \\
2 & 6 & 2\cdot3^1 \\
3 & 18 & 2\cdot3^2 \\
4 & 54 & 2\cdot3^3
\end{tabular}
\end{table}$
The patern here is obvious. Let's write it down:
$N=2\cdot3^{n-1}$
This formula gives us a number of flowers planted in the n-th month.

Find the equation of the line through (6,8) which is parallel to the line y=4x−6.

Ratling [72]

Answer:

$y=4x-16$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope of the line and b is the y-intercept (the value of y when x is 0)
Parallel lines always have the same slope

1) Determine the slope (m)

$y=4x-6$

4 is in the place of m, making it the slope. Because parallel lines have the same slope, the slope of the line is therefore 4. Plug this into $y=mx+b$ :

$y=4x+b$

2) Determine the y-intercept (b)

$y=4x+b$

Plug in the given point (6,8) and solve for b

$8=4(6)+b\\8=24+b$

Subtract 24 from both sides to isolate b

$8-24=24+b-24\\-16=b$

Therefore, the y-intercept of the line is -16. Plug this back into $y=4x+b$ :

$y=4x-16$

I hope this helps!
