I would either graph these (which would be a easiest) then you would see a line that goes through (0, -2) on the y-axis
And you can either determine the slope from the graph or pick two points above and find the slope.

or spread them out evenly and fill out the missing pieces.

-8. -4

-4. -3

0

4. -1

6. -0.5

8

12. 1

Fill in the middle values and you can put (6,-0.5) on there

What pattern do u see? This way would be pretty hard.

Equation: y=(1/4)x-2

Evaluate the geometric series

JulijaS [17]

Answer:

Option B is correct.

sum of given geometric series is, 255

Step-by-step explanation:

Evaluate the geometric series: $\sum_{i=1}^{8} 2^{i-1}$

we can write this as:

$1+2+4+.......+128$

Formula for the sum of the geometric series:

$S_n = \frac{a(r^n-1)}{r-1}$ for r > 1

where

a is the first term

n is the number of terms

r is the common ratio

In the given series:

common ratio (r) = 2>1, n = 8 and first term(a) = 1

Since,

$\frac{2}{1} = 2$

$\frac{4}{2} = 2$ and so on...

then substitute the given values in [1] we have;

$S_n = \frac{1((2)^8-1)}{2-1}$

$S_n = 256-1 = 255$

Therefore, the sum of given geometric series is, 255

There are many cylinders for which the height and radius are the same value. Let

VashaNatasha [74]

Answer:

Relation between V and c is represented as:

$V = \pi c^{3}$

When c is halved, V becomes $\frac{1}{8}$ of its initial value.

Step-by-step explanation:

Height of cylinder = Radius of cylinder = c

Volume of cylinder = V

As per formula:

$V = \pi r^{2} h$

Where $r$ is the radius of cylinder and

$h$ is the height of cylinder

Putting $r = h =c$

$V = \pi c^{2} \times c\\\Rightarrow V = \pi c^{3} ......(1)$

The values of c is halved:

Using equation (1), New volume:

$V' = \pi (\dfrac{c}{2})^3\\\Rightarrow \dfrac{1}{8} \pi c^{3}$

By equation (1), putting $\pi \times c^{3} = V$

$V' = \dfrac{1}{8} \times V$

So, when c is halved, V becomes $\frac{1}{8}$ of its initial value.

What are the exact solutions of x^2 = 5x + 2?

aleksandrvk [35]

Move everybody to one side
minus 5x+2 both sides
x^2-5x-2=0
use quadratic formula where
if you have
ax^2+bx+c=0
x= $\frac{-b+/- \sqrt{b^{2}-4ac} }{2a}$

1x^2-5x-2=0
a=1
b=-5
c=-2

x= $\frac{-(-5)+/- \sqrt{(-5)^{2}-4(1)(-2)} }{2(1)}$
x= $\frac{5+/- \sqrt{25+8} }{2}$
x= $\frac{5+/- \sqrt{33} }{2}$

aprox
x=5.372281323 or -0.3722813233
