Answer:
5800
Step-by-step explanation:
that is to the nearest hundred
1. ∠txu ≅ ∠tvs 1. given
2. ∠stv ≅ ∠utx 2. reflexive property
3. Δstu is equilateral 3. given
4. st ≅ ut 4. sides of an equilateral triangle are congruent
5. <u>Δxtu ≅ Δ vts </u> 5. AAS
6. ux ≅ sv 6. CPCTC
X-intercepts are zeroes of the parabola.
(x-x1)(x-x2)=(x+1.6)(x+3.2)=x² +1.6x+3.2x+5.12=x²+4.8x+5.12
y=x²+4.8x+5.12, but the y-int. is (0, 25.6),
So, our parabola should look like
y=5(x²+4.8x+5.12)
y=5x²+24x+25.6
