Answer:

w=15

Step-by-step explanation:

You need to solve the equation so that w is by its self. To get rid of -4 you add 4 to each side giving you w=15.

Answer:

-108

Step-by-step explanation:

About the easiest way to do this for small values of n is to compute each of the terms using the given recurrence relation.

$a_1=4\\\\a_2=-3a_1=-3(4)=-12\\\\a_3=-3a_2=-3(-12)=36\\\\a_4=-3a_3=-3(36)=-108\\\\\boxed{a_4=-108}$

_____

Alternate solution

You recognize that the recurrence relation describes a geometric sequence with a first term of 4 and a common ratio of -3. The n-th term of a geometric sequence is ...

$a_n=a_1\cdot r^{n-1} \qquad\text{for first term $a_1$ and common ratio $r$}$

Then the 4th term will be ...

$a_4=4\cdot(-3)^{4-1}=4\cdot(-27)=-108$

Solve for x parallel

umka2103 [35]

Answer:

x=5

Step-by-step explanation:

Hi there! So when it comes to these two angles, you have to set them equal to each other. From there, you have to isolate the x values, so I subtracted x from the 3x and added 15 to the -5. If you plug in the 5 for the x values, both give the value of 0, so it all checks out. I hope this helped! Please mark this as brainliest if I managed to get this correct. <3

Answer:

$m\angle FAD =42^o$

Step-by-step explanation:

Right Triangles

Right triangles are those who have a right angle, i.e. 90°. The other two angles must sum 90° to complete the 180° which must sum the internal angles of a triangle.

The image shows a circle with two similar triangles FAD and EAD. We know they are congruent because they share the same height and have a base of the same value (as indicated by the ticks). The segment AD must be perpendicular to FE since it comes from the center of the circle. We can conclude $\angle FDA$ is right, i.e. measures 90°.

We know $m\angle AFD = 48 ^o$ , so the required angle $\angle FAD$ must be 90°-48°=42°.

$m\angle FAD =42^o$
