Answer:
1,000,000
Step-by-step explanation:
length increased by 1000
width increased by 1000
1000 * 1000 = 1,000,000
Answer:
48
Step-by-step explanation:
Given
4a² + 6a - 3(a + 4) + 15 ← distribute parenthesis
= 4a² + 6a - 3a - 12 + 15 ← collect like terms
= 4a² + 3a + 3 ← substitute a = 3 into the expression
= 4(3)² + 3(3) + 3
= 4(9) + 9 + 3
= 36 + 9 + 3
= 48
Answer:
Step-by-step explanation:
We have that the focus is at (p,0) and that the directrix is x=-p. Take the point (-p,0) of the directrix. We know that the vertex of the parabola is at the middle point ot the line segment that joins the points (p,0) and (-p,0). To get the middle piont, we take the average coordinate by coordinate. That is, the middle point is . The general formula of a parabola of vertex (h,k) that opens to the right or to the left is given by
Where |p| is the distance from the focus to the vertex. If the parabola opens to the right, then p>0 and p<0 otherwise. In our case, h =0=k, so we get that
