Please solve for X and explain with steps

Mathematics
1 answer:
Snezhnost [94]2 years ago
7 0

log₃(-2 tan(<em>x</em>)) = 1/2

Write both sides as powers of 3, and use the property b^{\log_ba}=a:

3^{\log_3(-2\tan x)}=3^{\frac12}

-2 tan(<em>x</em>) = √3

Then solve for <em>x</em> :

tan(<em>x</em>) = -√3 / 2

<em>x</em> = arctan(-√3 / 2) + <em>nπ</em>

<em>x</em> = -arctan(√3 / 2) + <em>nπ</em>

where <em>n</em> is any integer.

Solve for x <br> Find ADB<br> Find BDC
NeTakaya

Answer:

x=12 ADB= 56 BDC= 54

Step-by-step explanation:

ADB and BDC are complementary, so they add up to 90 degrees. In other words ADB+BDC= 90 So I can input my knowns into the equation

(3x+10) + (4x-4) = 90

I combined like terms to give me 7x+6=90

Then I subtract 6 from both sides giving me 7x=84

Last I divide 7 on both sides. x=12

Then I input the x (12) into the equation and solve it from there

3(12)+10 and 4(12)-4

3(12)+10=56

4(12)-4=54

. . . I think. Hope this helps!

Solve 6x + 3) = 21.
LiRa [457]

Answer:

18x^2 - 9

Step-by-step explanation:

y = f(x)= 6x^3 - 9x + 4

dy/dx = d/dx(6x^3) - d/dx(9x) + d/dx (4)

=6.d/dx(x^3) - 9.d/dx (x) + d/dx. (4)

=6.3x^2 - 9.1 + 0 =18x^2 - 9
