Answer:
F(1,5)
Step-by-step explanation:
This is a vertical parabola.
The vertex is at (1,4).
The directrix is y=3.
The distance from the vertex to the directrix is p=1
The focus is (1,4+p), which is (1,4+1)
Therefore the focus is (1,5)
for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²
Volume = Bh = 17.5×10 = 175 cm³
The answer would be 97 when rounded to the nearest mile (if you were were going for length)
Step-by-step explanation:
2) 212*198 = 41 976
1) 80-37 = 43
9514 1404 393
Answer:
no solution
Step-by-step explanation:
Simplifying the given equation, you have ...
-6(x -2) +3x = -3(x +3) +21 . . . . . given
-6x +12 +3x = -3x -9 +21 . . . . . . eliminate parentheses
-3x +12 = -3x +13 . . . . . . . . . . . . collect terms
0 = 1 . . . . . . . . . . . . . add (3x-12) to both sides
There is no value of x that will make this true.
The equation has NO SOLUTION.
