Let's buils the intersection plane:
Point P is on AB and AP=2, then PB=3; point Q is on AE and AQ=1, then QE=4. Let P' be a point on CD such that CP'=2 and Q' be a point on the plane CDHG such that P'Q'=1 and P'Q' is perpendicular to CD. The line CQ' intersects HD at point R and the plane CPQR is intersection plane.
Consider triangles ΔCDR and ΔCP'Q', they are similar. So,
![\frac{CP'}{CD}= \frac{P'Q'}{RD} \\ \frac{2}{5} =\frac{1}{RD} \\ RD=2.5](https://tex.z-dn.net/?f=%20%5Cfrac%7BCP%27%7D%7BCD%7D%3D%20%20%5Cfrac%7BP%27Q%27%7D%7BRD%7D%20%20%5C%5C%20%20%5Cfrac%7B2%7D%7B5%7D%20%20%3D%5Cfrac%7B1%7D%7BRD%7D%20%20%5C%5C%20RD%3D2.5)
,
so R is a midlepoint of the side HD (for details see picture).
Answer:
b) exponential growth
Step-by-step explanation:
The value of an investment of $3,500 over "t" years at 4.5% interest is represented by the expression
![3500(1.045)^{t}](https://tex.z-dn.net/?f=3500%281.045%29%5E%7Bt%7D)
The general form of exponential expresion y = a.![b^{x}](https://tex.z-dn.net/?f=b%5E%7Bx%7D)
If exponent "x" is positive, then it is exponential growth. If exponent "x" is negative, then it is exponential decay.
Our given expression is in the form of exponent. Here the exponent "t" represents the number of years. It must be positive.
Therefore, our given expression is b. exponential growth.
