Answer:

Exponential Decay

Step-by-step explanation:

It's exponential growth when your base value is > 1. Example:

1.3ˣ, 2ˣ, 7ˣ, 999ˣ

It's exponential decay when the base value is < 1. Example:

0.9ˣ, 0.45ˣ, (1/2)ˣ, 0.79ˣ, .999ˣ

It's neither when the base value = 1. Example:

1ˣ

Which two values of x are roots

FrozenT [24]

The answer is C.

To solve these types of equations you first need to make sure that you equation is equal to 0. In this case all of the numbers are already on the same side so no work needs to be done there. Then we can get a, b and c values for the quadratic equation by looking at the coefficients.

a = 4 (number attached to x^2)
b = -6 (number attached to x)
c = 1 (number with no variable attached)

Now we can put this into the quadratic equation.

$\frac{-b +/- \sqrt{ b^{2} -4ac} }{2a}$

$\frac{6 +/- \sqrt{ -6^{2} -4(4)(1)} }{2(4)}$

$\frac{6 +/- \sqrt{20} }{8}$

Factorise the given question: 3p^-7p-6

My name is Ann [436]

Answer:

(p−3)⋅(3p+2)

Step-by-step explanation:

STEP 1 :

Equation at the end of step 1

(3p2 - 7p) - 6

STEP 2 :

Trying to factor by splitting the middle term

2.1 Factoring 3p2-7p-6

The first term is, 3p2 its coefficient is 3 .

The middle term is, -7p its coefficient is -7 .

The last term, "the constant", is -6

Step-1 : Multiply the coefficient of the first term by the constant 3 • -6 = -18

Step-2 : Find two factors of -18 whose sum equals the coefficient of the middle term, which is -7 .

-18 + 1 = -17

-9 +2 = -7 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and 2

3p2 - 9p + 2p - 6

Step-4 : Add up the first 2 terms, pulling out like factors :

3p • (p-3)

Add up the last 2 terms, pulling out common factors :

2 • (p-3)

Step-5 : Add up the four terms of step 4 :

(3p+2) • (p-3)

Which is the desired factorization

Final result :

(p - 3) • (3p + 2)
