What is the answer for m^2-5m-14=0?

tensa zangetsu [6.8K]

Answer: m = 7 or -2

Step-by-step explanation:

Quadratic Formula! $\frac{{-b (+/-)\sqrt{(b^{2}-4ac }}}{2a}$

Polynomial Form: $ax^{2} +bx+c$

So in this example a: 1 b: -5 c: -14

You get: $\frac{{-(-5) (+/-)\sqrt{((-5)^{2}-4(1)(-14) }}}{2(1)}$

m = 7 or -2

Check by plugging a value back in for m

$(7)^{2} -5(7)-14=0?\\(-2)^{2} -5(-2)-14=0?\\$

True for both.

Lori buys a $400 certificate deposit that earns 1.8% interest compounded monthly how much will a cd be worth in six years

Firlakuza [10]

Answer:

$1445.11

Step-by-step explanation:

The formula to use would be:

$F=P(1+r)^t$

Where

F is the future amount (what we want to find)

P is the present (principal) amount (this is 400)

r is the rate of interest, monthly (1.8% or 0.018)

t is the time in months (6 years = 6 * 12 = 72)

Now substituting, we get:

$F=P(1+r)^t\\F=400(1+0.018)^{72}\\F = 400(1.018)^{72}\\F=1445.11$

After 6 years, the CD will be worth $1445.11
