Find the maximum/minimum value.<br> y= -2x2 - 16x - 29

nikdorinn [45]

Maximum value : x=-4

The graph of the parabola opens down, since the value of a (-2) is a negative coefficient. This means the parabola has a maximum value, not a minimum value. The vertex of the parabola is -4, which is the maximum value of the graph.

Answer:

1) 1023

2) 8

Step-by-step explanation:

1)

Given:

$a_{n+1}=2\cdot a_n + 1$ and $a_1 = 1$

Then, the next table can be computed (only the first terms are explicitely shown)

n $a_n$

1 1

2 $a_{2}=2\cdot 1 + 1 =$ 3

3 $a_{3}=2\cdot 3 + 1 =$ 7

4 15

5 31

6 63

7 127

8 255

9 511

10 1023

2)

Given

$t_n=n^2-2n$

Then, the next table can be computed

n $t_n$

1 $t_1=1^2-2(1) =$ -1

2 $t_2=2^2-2(2) =$ 0

3 $t_3=3^2-2(3) =$ 3

4 $t_4=4^2-2(4) =$ 8

How many different triangles can be constructed with three angles, each measuring 30°?

HACTEHA [7]

None
Triangles have a sum of 180 degress
30(3) = 90 so it will NEVER work

Gavin was thinking of a number. Gavin halves the number and gets an answer of 34.3. Form an equation with x as information.

Lostsunrise [7]

Gavin's number is 68.6

Equation: 1/2(x) = 34.3

Use inverse operations on both sides.

1/2(x) = 1x or x = 34.3(2)

34.3(2) = 68.6

Thus, x equals 68.6
