3.
baherus [9]

Answer:

3. \overline{PM}\cong \overline{ON} Distances between two parallel lines \overline{MN} \ and\ \overline{PO}

4. \overline{AC} = \overline{CE}: Reason; Corresponding part of ΔACB and ΔDCE

C is the midpoint of \overline{AE}: Reason;  \overline{AC} = \overline{CE}: Definition of midpoint

Step-by-step explanation:

3. A parallelogram is defined as a quadrilateral with two opposite sides equal and parallel and having equal opposite interior angles

MNOP is a parallelogram: Reason; Given

\overline{PM}\left |  \right |\overline{ON} : Reason; Opposite sides of a parallelogram

∠NOM ≅ ∠OMP: Reason Alternate interior angles

\overline{MN}\left |  \right |\overline{PO}: Reason; Opposite sides of a parallelogram

∠NMO ≅ ∠MOP: Reason Alternate interior angles

\overline{PM}\cong \overline{ON} Distances between two parallel lines \overline{MN} \ and\ \overline{PO}

4. \overline{AB}\left |  \right |\overline{DE} : Reason; Given

∠EAB ≅ ∠AED: Reason; Alternate int. ∠s Thm

∠ABC ≅ ∠EDB : Reason; Alternate int. ∠s Thm

C is the midpoint of  \overline{BD}: Reason; Given

\overline{BC} = \overline{CD}: Reason; Definition of midpoint

Therefore, ΔACB ≅ ΔDCE: Reason Angle Angle Side (AAS) Theorem

\overline{AC} = \overline{CE}: Reason; Corresponding part of ΔACB and ΔDCE

C is the midpoint of \overline{AE}: Reason; Definition of midpoint

An exponential function f(x)=a⋅bx passes through the points (0, 4) and (2, 64). What are the values of a and b?
Flura [38]

Answer:

a=b=4

Step-by-step explanation:

f(x) = a\cdot b^x\\f(0) = a = 4\\f(2) = 4b^{2} = 64 \rightarrow b = 4\\ f(x) = 4 \cdot 4^x
