X2+10x+24=(x+a)(x+a) B is An Interger Find Algebracally All Possible Values of. B
Vedmedyk [2.9K]
(x+a)(x+a)=x^2+2ax+a^2\\\\&#10;2a=10 \wedge a^2=24\\&#10;a=5 \wedge (a=\sqrt{24} \vee a=-\sqrt{24})\\&#10;a=5 \wedge (a=2\sqrt{6} \vee a=-2\sqrt{6})

The above is contradiction, so there are no such values of 'a'.

Slav-nsk [51]

Answer:

The budget in 2010 is $4453.10915 billion

Step-by-step explanation:

We are given exponential function as

f(t)=39.4e^{0.0787932t}

where t is the time in years since 1950

now, we can find time in 2010

t=2010-1950=60

now, we can plug t=60

and we get

f(60)=39.4e^{0.0787932\times 60}

we get

f(60)=4453.10915

So, the budget in 2010 is $4453.10915 billion
