Product is multiplying. when you multiply a letter with a number you don't put any symbols so it would be 8c
The answer would be 5x+5y
...6 and 10 are roots, so x – 6 and x – 10 are factors.
y = a(x – 6)(x – 10).....plug in the point (8, 2) and solve for a:
2 = a(8 – 6)(8 – 10)
2 = –4a
a = –1/2
...y = (–1/2)(x – 6)(x – 10)
...y = (–1/2)(x² – 16x + 60)
...y = (–x²/2) + 8x – 30 <<<------Answer, or:
...y = (–1/2)(x – 8)² + 2 <<<------Answer
Answer:
Surface area is the sum of all of the areas of the faces in a solid figure. To find the surface area, we must be able to calculate the area of each face and then add these areas together. A net is a two-dimensional diagram of a three-dimensional figure. With a net, we can see each face of the pyramid more clearly. To find the surface area, we need to calculate the area for each face in the net, the sides and the base. The side faces of a pyramid are always triangles, so we use the area formula for triangles to calculate their area: A=1/2 bh (BASE TIMES HEIGHT)..
Step-by-step explanation:
40℅ of 152.5 = 61
250% of 61 = 152.5
