Answer:

middle

Step by step explanation:

they are saying that f(x) = g(x)

so you will make the two functions equal to each other:

-1/2x - 2 = -1

this creates a linear equation , which you can solve to find x:

-1/2x - 2 = -1

-1/2x = -1 + 2

-1/2x = 1

-1x= 1 × 2

-1x = 2

x = -2

Now you know the value of x. the value of the y coordinate is already given: g(x) = -1. Hence, y = -1

because, <u>g</u><u>(</u><u>x</u><u>)</u><u> </u><u>=</u><u> </u><u>f</u><u>(</u><u>x</u><u>)</u><u> </u><u>=</u><u> </u><u>y</u><u> </u>

(-2 , -1)

Look for the line that passes this coordinate; and it is the middle one.

Hope I was able to help. Good luck!

Answer:

B) 6.68

Step-by-step explanation:

Use Cosine.

Cosine= Adjacent ÷ Hypotenuse

In this case the base you want to find is adjacent to the angle, 42°. Hence,

Cos (42)= adjacent ÷ hypotenuse

Cos (42) = x ÷ 9

x = Cos (42) × 9. Input that into your calculator.

x= 6.68

To remember the trigonometric ratios/formulas

Use the acronym, SOHCAHTOA

Hope this helps!!!!

What is the solution to the rational equation x over 2x plus 1 minus 1 over 4 equals 2 over 2x plus 1
aalyn [17]
We want to solve
\frac{x}{2x+1} - \frac{1}{4} = \frac{2}{2x+1}

Subtract 2/(2x+1) from each side.
\frac{x}{2x+1} - \frac{2}{2x+1y} - \frac{1}{4} = 0

Add 1/4 to each side, and simplify the left side.
\frac{x-2}{2x+1} = \frac{1}{4}

Cross multiply.
4(x - 2) = 1(2x + 1)
4x - 8 = 2x + 1

Simplify and solve for x.
4x - 2x = 1 + 8
2x = 9
x = 9/2   or x = 4 1/2.

Answer:  x =  \frac{9}{2} \,\, or \,\, x = 4 \frac{1}{2}

Answer:

The number of weeks required = 216 weeks

Step-by-step explanation:

Given that:

Margin of Error E = 200

Confidence interval = 95% = 0.95

Level of SIgnificance  = 1 - C.I

= 1 - 0.95

= 0.05

Standard deviation = 1500

The Critical value for Z :

Z_{\alpha/2} =Z_{0.05/2}  \\ \\  = Z_{0.025} =  1.96

The number of weeks( i.e the sample size (n) ) required is :

n = (\dfrac{Z_{\alpha/2} \times \sigma}{E})^2

n = (\dfrac{1.96 \times 1500}{200})^2

n = (14.7)^2

n = 216.09

n ≅ 216 weeks
