Find the length x. pls help

scoray [572]

Answer:

x = 6

Step-by-step explanation:

To find x we set up an equation as so:

$\frac{4.5}{x} =\frac{6}{8}$

Then we solve by multiplying 4.5 by 8 and 6 by x

$6x=36$ Solve for x

$\frac{6x}{6} =\frac{36}{6}$ x = 6

To check our answer when we substitute x or 6 we divide to make sure both sides equal the same number

$\frac{4.5}{6} =\frac{6}{8}$ when divided both equals 0.75

Let log p/n=6 and log m/n=8 what is the relationship between p and m?

Mrac [35]

By the laws of logs
log p/n = log p - log n = 6
log m/n = log m - log n = 8 subtract

log m - log p = 2

log m/p = 2

So m / p = 100

Identify the vertex and directrix of each. y = x2 + 2x - 4

sergey [27]

Answer:

See below

Step-by-step explanation:

Convert equation to vertex form $y=(x-h)^2+k$ by completing the square:

$y=x^2+2x-4$

$y+5=x^2+2x-4+5$

$y+5=x^2+2x+1$

$y+5=(x+1)^2$

$y=(x+1)^2-5$

Vertex:

$(h,k)\rightarrow(-1,-5)$

Directrix:

$y=k-\frac{1}{4a}\rightarrow y=-5-\frac{1}{4(1)}\rightarrow y=-\frac{21}{4}$
