Half one is 1/2;
half three is 3/2;
Thus, if f(x) represents annual growth, f(x)/2 shows it every half-year, like this:
![\dfrac{f(x)}{2} = \dfrac{15\cdot 2^x}{2} \\ \\ \dfrac{f(x)}{2} = \dfrac{15}{2}\cdot 2^x](https://tex.z-dn.net/?f=%5Cdfrac%7Bf%28x%29%7D%7B2%7D%20%3D%20%5Cdfrac%7B15%5Ccdot%202%5Ex%7D%7B2%7D%20%5C%5C%20%20%5C%5C%20%0A%5Cdfrac%7Bf%28x%29%7D%7B2%7D%20%3D%20%5Cdfrac%7B15%7D%7B2%7D%5Ccdot%202%5Ex)
Written in plain text: f(x)=15/2*2^x
Answer:
y=-5/2x+4
Step-by-step explanation:
find the slope by using y2-y1/x2-x1
-1-19/2-(-4)
simplify
-20/8
simplify
-5/2
use slope-intercept form, y=mx+b
since we know the slope, find b
plug in one of the ordered pairs into the equation
-1=(-5/2)(2)+b
simplify
-1= -10/2+b
simplify
-1=-5+b
add 5 to both sides
b=4
plug b into y=-5/2x+b
y=-5/2x+4
Divide 5.6 by 8 which is 0.7. Since the image of the ant is 8 times bigger we need to divide by 8 to make it actual size.
The ant's actual length is 0.7 cm.
Hey! You just have to square root the 2 and 5 then multiply by 11 so the answer I came up with is 34.78505426185218
I hope I helped!
The number is 24. If 8 is one third of the number, you multiply 8 by 3 to find the number, which is 24.
