Answer:

$\sqrt{66}$

Step-by-step explanation:

By geometric mean property:

$BD = \sqrt{6 \times 5} = \sqrt{30} \\ \\ In \: \triangle ABD: \\ by \: pythagoras \: theorem : \\ \\ AD^2 = AB^2 + BD^2 \\ \\ {x}^{2} = {6}^{2} + {( \sqrt{30}) }^{2} \\ \\ {x}^{2} = 36 + 30 \\ \\ {x}^{2} = 66 \\ \\ x = \sqrt{66}$

5+2x=2x+6 What's the answer?

Marina86 [1]

Answer:

Below!

Step-by-step explanation:

We can solve this with the help of equations.

5 + 2x = 2x + 6
=> -2x + 2x = -5 + 6
=> 0 ≠ 1

Since we are getting 0 ≠ 1 as our result, the problem has no solution.

Hoped this helped.

First analyze your question. Barbara has a goal to read 45 minutes every day. If she meets her goal, how many minutes will she have read in 360 days?
So....
360*45=16,200

The answer is D. 16,200

Good luck with your studies, I hope this helps!!

What is the midline equation of the function g(x)=3\sin(2x-1)+4g(x)=3sin(2x−1)+4g, (, x, ), equals, 3, sine, (, 2, x, minus, 1,

Aleksandr-060686 [28]

Answer:

Required equation of midline is x=4.

Step-by-step explanation:

Given function is,

$g(x)=3\sin (2x-1)+4\hfill (1)$

In standerd form (1) can be written as,

$a\sin (bx+c)\pm d$

where,

|a|= amplitude.

b= vertical shift.

c= horizontal shift.

Midline is the line which runs between maximum and minimum value.

In this problem,

a=3, b=2, c=-1, d=4

So amplitude a=3 and graph is shifted 4 units in positive y-axis.

Therefore,

Maximum value = d + a = 4 + 3 = 7

Minumum value = d - a = 4 - 3 = 1

Midline will be centered of the region (7, 1) that is at 4.

Hence equation of midline is x=4.
