Answer:

Step-by-step explanation:

a^{m}* a^{n}=a^{m+n}\\\\\\(\frac{-1}{2})^{-19}*(\frac{-1}{2})^{8}=(\frac{-1}{2})^{-2x +1}\\\\(\frac{-1}{2})^{-19+8}=(\frac{-1}{2})^{-2x+1}\\\\\\(\frac{-1}{2})^{-11}=(\frac{-1}{2})^{-2x+1}

As bases are equal in boht sides, we can compare the exponents.

-2x + 1 = -11

Subtract 1 form both sides

-2x = -11 - 1

-2x = -12

Divide both sides by -2

x = -12/-2

x = 6

Find the values of c such that the area of the region bounded by the parabola
KATRIN_1 [288]

<u>Solution-</u>

The two parabolas are,

y=16x^2-c^2 \ and \ y=c^2-16x^2

By solving the above two equations we calculate where the two parabolas meet,

So \ 16x^2-c^2 = c^2-16x^2 \Rightarrow 32x^2=2c^2 \Rightarrow x=\frac{1}{4}c

Given the symmetry, the area bounded by the two parabolas is twice the area bounded by either parabola with the x-axis.

\therefore Area=2\int_{-c}^{c}y.dx= 2\int_{-c}^{c}(16x^2-c^2).dx\\=2[\frac{16}{3}x^3-c^2x]_{-c}^{ \ c}=2[(\frac{16}{3}c^3-c^3)-(-\frac{16}{3}c^3+c^3)]=2[\frac{32}{3}c^3-2c^3]=2(\frac{26c^3}{3})\\=\frac{52c^3}{3}

So \frac{52c^3}{3}=\frac{250}{3}\Rightarrow c=\sqrt[3]{\frac{250}{52}}=1.68

What is (f . g) (x)?
sergeinik [125]
I think you’re answer is option 1: 3x^2+5.

Explanation:

Evaluate f(x^2+2) by substituting in the value of g into f.
f(x^2+2)=3(x^2+2)-1

Then apply distributive property.
f(x^2+2)=3x^2+3•2-1

Then multiply 3 by 2.
f(x^2+2)=3x^2+6-1

Then subtract 1 from 6.
f(x^2+2)=3x^2+5

lakkis [162]

Answer:

8 is the required answer.

Step-by-step explanation:

In a polynomial, the leading term is the term with the highest power of x.

8x^5  is the leading term. So, coefficient is 8.

Best Regards!
