1.3 Find the next number in the sequence: -16; -9; -2: _ a. 12 6.7 C. 5 d.-5 1.4 3 = b.1 6.6 d. 27​
iogann1982 [59]

Answer:

given sequence, -16; -9; -2: _

first term(a)=-16

common difference(d)=-9-(-16)=7

next term is 4

so

4th term=a+(n-1)d

=-16+(4-1)7=-16+21=5

<u>c.5</u>

If the discriminant b^2-4ac is 0, then you have TWO EQUAL, REAL ROOTS.

If you're given the x-intercepts, you can determine the factors of the polynomial as follows:   Take -3, change the sign and write (x+3).  Take 5, change the sign and write (x-5).  Then the eq'n of the parabola is

f(x) = (x+3)(x-5) = x^2 - 2x -15, in which a=1, b = -2 and c= -15.

You can find the x-coordinate of the vertex, which is also the equation of the axis of symmetry, using

x= -b / (2a).    Here, x = -(-2) / (2[1]), or  x = 1

Find the y-coordinate by subbing 1 for x in the equation above:

y = (1)^2 - 2(1) - 15  =  1 - 2 - 15  =  -16

The vertex is at (1, -16) and the equation of the axis of symm. is x = 1.

The price of an item has risen to $156 today. Yesterday it was $65 . Find the percentage increase.
faltersainse [42]
That's a BIG increase in price!  What cost $65 yesterday is now $156.  What was the increase?  $156 - $65 = $91.

Next:  $91 is what fraction of $65?  Divide.  Answer:  1.4.

Finally, multiply this last result by 100%:  140% (answer)
