Evaluate the expression 263 + 5 when b = 3. 263 +5 = 2(3): +5 =

ExtremeBDS [4]

Given:

The expression is:

$2b^3+5$

To find:

The value of the given expression when $b=3$ .

Solution:

We have,

$2b^3+5$

Substituting $b=3$ in the above expression, we get

$2b^3+5=2(3)^3+5$

$2b^3+5=2(27)+5$

$2b^3+5=54+5$

$2b^3+5=59$

Therefore, the value of given expression at $b=3$ is 59.

Identify the zeros of the function f(x) = 4x2 − 8x − 1 using the Quadratic Formula. HELP ASAP!!

forsale [732]

$1+\dfrac{\sqrt{5}}{2},1-\dfrac{\sqrt{5}}{2}$

Step-by-step explanation:

The given equation is $4x^{2}-8x-1$

Let $a$ be the coefficient of $x^{2}$

Let $b$ be the coefficient of $x$

Let $c$ be the constant.

Then the roots α,β for the equation $ax^{2}+bx+c$ are $\dfrac{-b+\sqrt{b^{2}-4ac} }{2a},\dfrac{-b-\sqrt{b^{2}-4ac} }{2a}$

So,α= $\frac{-b+\sqrt{b^{2}-4ac} }{2a}=\frac{8+\sqrt{64+16} }{8}=\frac{8+4\sqrt{5}}{8}=1+\frac{\sqrt{5}}{2}$

β= $\frac{-b-\sqrt{b^{2}-4ac} }{2a}=\frac{8-\sqrt{64+16} }{8}=\frac{8-4\sqrt{5}}{8}=1-\frac{\sqrt{5}}{2}$ .

So the roots are $1+\frac{\sqrt{5}}{2},1+\frac{\sqrt{5}}{2}$

To solve the equation w/8 - 4 = 20, you would first add 4 to each side and then divide each side by 8.

bearhunter [10]

False because, you DO add 4 to the sides but you would multiply the 8 because you to the opposite to cancel it out
