Find the 78th term of the arithmetic sequence -12,-13,-14,

creativ13 [48]

Answer:

-89

Step-by-step explanation:

The first term of the sequence is a1 = -12.

The common difference between terms is ...

d = -13 -(-12) = -1

The generic term is given by ...

an = a1 +d(n -1)

Then the 78th term is ...

a78 = -12 +(-1)(78 -1) = -12 -77

a78 = -89

Line t intersects line u as shown below What is the value of x

Rudiy27

Answer:

x = 117 degrees

Step-by-step explanation:

Find the diagram attached

From the diagram, the angle at the top left on line t is equal to theta of the top left on line u and is equal to 117 degrees (corresponding angle)

Also the angle angle on the top left on line u will be equal to x (vertically opposite angle)

Hence the value of x = 117 degrees (vertically opposite to each other on line u)

Which of the following are possible values of r? <img src="https://tex.z-dn.net/?f=%20%7Br%7D%5E%7B2%20%7D%20%20%3D%20%20%5Cf

marshall27 [118]

Answer:

$r=\frac{\sqrt{3} }{4}$ and $r=-\frac{\sqrt{3} }{4}$

Step-by-step explanation:

when you solve for r in the given equation, you need to apply the square root property, which gives positive and negative answers (both should therefore be considered):

$r^2=\frac{3}{16} \\r=+/-\sqrt{\frac{3}{16}} \\r=+/-\frac{\sqrt{3} }{4}$

then you need to include these two possible solutions:

$r=\frac{\sqrt{3} }{4}$ and $r=-\frac{\sqrt{3} }{4}$
