Answer:
1. (7,-9)
2. (4,0) and (10,0)
3. (3,0) and (-3,0)
4. (0,-9)
5. (-1,-32)
Step-by-step explanation:
To find the vertex use the formula
First make the equation into a quadratic equation.
Now it is in the form
Now we can substitute the values
Now we have 7 as our x value for the vertex we can substitute for y,
So the vertex for 1 is (7,-9)
To find the intercepts for 2 & 3, they basically already give it to you. You just need to find a value for x for x-4 that will equal it to 0 and another for x for x-10 that will equal it to 0.
4 is slightly different but start the same,
Here, c (9) just shows the graph move down 9, so the y intercept = 9.
5 is the same process as 1,
Vertex,
Substitute,
So the vertex is (-1,-32)
Answer:
28 and 12t
Step-by-step explanation:
4 x 7
4 x 3t
Simple interest: i = p * r * t; compound interest would be A=p(1+r/n)^(nt)
Here, A = $500 (1.10)^2 = $605 (answer for "once per year."
Once per month:
A = $500 (1 + 0.10/12)^(12*2) = $610.20
Once per week: Can y ou figure that out? # of compounding periods is 12 per year in this problem.
<span>A cube is a geometric three-dimensional solid object. It constitutes
6 square faces, sides and three meeting at each vertex. It is the only regular
hexahedron. A cube has a fixed number of
perpendicular angles. Typically, it has 8 perpendicular angles and each spigolo
or corner has 3 angles. Since it has 8 perpendicular (⊥) angles and 3 angles in
each corner, it makes up 24 angles.
All 8 ⊥ angles and 3 angles in each corner mean: 8*3=24.
Therefore, a cube has 24 right angles.</span>
