### A botanist measures a plant, in feet, at the beginning of each month and notices that the measurements form a geometric sequence, as shown below. 2, 2.2, 2.42, 2.662, ... If the first measurement was taken on September 1, about how tall was the plant three months before, on June 1, assuming the same growth pattern? A) 0.9 ft B) 1.5 ft C) 1.7 ft D) 2.0 ft

**Answer: Choice B) 1.5 ft**

-------------------------------------------------------------------------

Work Shown:

r = common ratio

r = (second term)/(first term)

r = 2.2/2

r = 1.1

Each term is multiplied by 1.1 to get the next term

Eg:

term 2 = 1.1*(term 1)

term 2 = 1.1*2

term 2 = 2.2

Let x be the value three slots before the value 2

So we have x, x*r, x*r^2, x*r^3 where

x = value in June

x*r = value in July

x*r^2 = value in August

x*r^3 = value in September

We just found that r = 1.1. We also know that the value in September is 2. So this means

x*r^3 = 2

x*(1.1^3) = 2

x*1.331 = 2

x*1.331/1.331 = 2/1.331

x = 1.5026 approximately

This rounds to 1.5

### Which value represents the horizontal translation from the graph of the parent function f(x) = x^2 to the graph of the function g(x) = (x-4)^2+2?

g(x)=f(x-h)+k

=f(x-4)^2+2

### What transformation has changed the parent function f(x) = log5x to its new appearance shown in the graph below logarithmic graph passing through point 5, negative 2.

f(x)=log(5x)

We want the curve to pass through (5,-2)

We can move the curve along the plot adding something in the formula. Let’s call that z.

You can put z in different parts of the formula and still find a z value that makes it pass through the point (5,-2). I will choose to put it inside the log:

f(x)=log(5x+z)

f(5)=-2

log(5*5+z)=-2

log(25+z)=-2

10^-2 = 25+z

10^-2 – 25 = z

z=1/100-25 = 1/100-2500/100=-2499/100 = -24.99

Let’s verify:

f(5)= log(5*5-24.99)=-2

So the formula: f(x)=log(5x-24.99) passes through the point (5,-2)

### C2/d at c = 6, d =3 Really confused on this one Can you evaluate the algebraic expressions for the given values of each variable? please

C^2 = 6^2 = 6*6 = 36

Note how I replaced the "C" with 6, because C = 6

Squaring a number is the same as multiplying it by itself.

Once you know the value of C^2, you divide it over the value for d, which is 3

So,

(C^2)/d = (36)/3 = 12

The final answer is 12

### Write the slope-intercept inequality for the graph below. Also please explain this one if you can!

**Answer: y <= -3x + 3**

-----------------------------------------

Explanation: The slope of the boundary line is -3 because we go down 3 over 1 each time we go from point to point. We can use the slope formula to get

m = (y2-y1)/(x2-x1)

m = (-3-3)/(2-0)

m = -6/2

m = -3

The y intercept is 3 because this is the location on the y axis where the graph crosses, so b = 3

Therefore the boundary line equation is y = -3x+3. Note how it's in the form y = mx+b where m = -3 and b = 3

The boundary line is solid. The shading is below the boundary line. So we change the equal sign to a "less than or equal to" sign to get the final answer of y <= -3x+3
