Answer:

no real roots

Step-by-step explanation:

9x²+12x+14

recall that for a quadratic equation ax²+bx+c, the discriminant = b²- 4ac

In our case,

discriminant,

= b²- 4ac

= 12² - 4(9)(14)

= 144 - 504

= -360

because the discriminant is negative, there are no real roots.

Answer:

the number of real roots for this equation 9x^2+12x+14 is :

0 (zero)

Step-by-step explanation:

Let Δ represent the discriminant

Δ = b² - 4ac = 12² - 4(9)(14) = -360

since Δ < 0 then it doesn’t have any real root.

florin(x) contains the point (0,1), so the inverse of florin(x) must contain the point , which is not on the line g(x). The func
Alex787 [66]

Answer:

The function g(x) will not contain point (0,1).

Step-by-step explanation:

If a function contains a point then its inverse also contains the point.

Now, in this question florin(x) is a function that contains the point (0, 1).

And the inverse of the function florin(x) will also contain the point (0, 1).  

But this inverse function is not g(x).  

So, the function g(x) will not contain point (0,1). ( Answer )

8. What happens to acceleration when the velocity changes by the same<br> amount over time?
Nookie1986 [14]

Answer:

The acceleration will also be uniform when velocity changes by the same amount over time.

Step-by-step explanation:

Acceleration is defined as a rate of change of velocity per unit time.

Unit of the acceleration is m/s^{2}

So,here when the velocity changes by the same amount over time, the change here will be <u>UNIFORM</u>.

Hence, the acceleration will also be uniform when velocity changes by the same amount over time.

The sum of the first 15 terms of a geometric sequence with 7 as the first term and a common ratio of -3 is __________.
Andre45 [30]

Step-by-step explanation:

the formula for the sum of the first n terms of a geometric sequence is

Sn = s1(1 - r^n)/(1 - r)

with r being the common ratio and s1 is the first term.

so,

S15 = 7×(1 - (-3)¹⁵)/(1 - -3) = 7×(1 - -14,348,907)/4 =

= 7×14,348,908/4 = 7×3,587,227 = 25,110,589
