Answer:

t(13) = 14

Step-by-step explanation:

Given t(11) = 22 and d = - 4

Then to obtain the next term in the sequence subtract 4 from the previous term, that is

f(12) = f(11) - 4 = 22 - 4 = 18

t(13) = t(12) - 4 = 18 - 4 = 14

Answer:

Step-by-step explanation:

I hope this means t_11 = 22

If it means t(11) = mx + b where x winds up being 11 and t(x) = 22, we have an entirely different problem. I'll try them both

t_11 = 22

t_11 = 22

d = - 4

what is a (where does this thing start).

L = a + (n - 1)*d

22 = a + (11 - 1)*-4

22 = a + 10*-4

22 = a - 40

a = 62

So finding t(13)  is

L = 62 + (13 - 1)*-4

L = 62 + 12 * - 4

L = 62 - 48

L = 14

======================

I think this is the only way to interpret it. If you get an answer explaining it, I'd take that answer.

Answer:

Total surface area = 184.86 cm²

Step-by-step explanation:

If we see the the diagram, we can find that the net of this triangular prism includes:

2 triangles each with the dimension of one side 4.3cm, second side 5.2cm and third side 6.75 cm

3 rectangles each with the dimensions of (6.75×10)cm, (5.2×10)cm and (4.3×10)cm

Surface area of triangle with a,b and c side:

s=(a+b+c)/2

Area= √s(s−a)(s−b)(s−c)

Area = 11.18cm²

For 2 triangle:

Area = 22.36cm²

Surface Area of Rectangles:

Area = (6.75×10)cm + (5.2×10)cm + (4.3×10)cm

Area = 162.5 cm²

Total surface area = area of 2 triangle + area of 3 rectangles:

Total surface area = 22.36 + 162.5

Total surface area = 184.86 cm²

13. Find the vertex of f(x)=x2 -6x +8 .
Mekhanik [1.2K]

9514 1404 393

Answer:

  a  (3,-1)

Step-by-step explanation:

The number that "completes the square" is the square of half the x-coefficient, (-6/2)^2 = 9. Rearranging the given function to include the square trinomial, we have ...

  f(x) = x^2 -6x +9 -1 . . . . . . . here, we have 8 = 9 - 1

  f(x) = (x -3)^2 -1 . . . . . . . . . . vertex form

Comparing this to the generic vertex form ...

  f(x) = (x -h)^2 +k . . . . . . . vertex at (h, k)

we see that h=3 and k=-1.

The vertex is (h, k) = (3, -1).
