<h3>Answer:</h3>

(2.8×10¹)x⁶y⁴

<h3>Step-by-step explanation:</h3>

Multiplication can be done in the usual way, then the number converted to scientific notation. Scientific notation does not apply to the variables.

$(7x^3y^2)(4x^3y^2)=(7\cdot 4)x^{3+3}y^{2+2}=28x^6y^4\\\\=2.8\cdot 10^1x^6y^4$

_____

If you write the numbers in scientific notation to start, then do the multiplication, the effect is virtually the same: an adjustment is needed in the product to get it back to scientific notation.

(7)(4) = (7×10⁰)(4×10⁰) = 7·4×10⁰⁺⁰ = 28×10⁰ = 2.8×10¹

maria [59]

Answer:

v=206ft/s , a=120ft/s

Step-by-step explanation:

We are given the equation of displacement

$S = 6t^3 + 6t^2 + 8t + 3,$

velocity = ds/dt

upon differentiating the given equation

ds/dt = $18t^2 + 12t + 8$

upon substituting t = 3

v = 206ft/s

Acceleration

a= dv/dt

upon differentiating

dv/dt = 36t + 12

put t= 3

a=120ft/s

4v^2 + 8v + 5 = 10 What would I add to this equation to create a perfect square?

Dvinal [7]

Answer:

v₁ = 2.5; v₂ = 0.5.

Step-by-step explanation:

4v² + 8v + 5 = 10

4v² + 8v + 5 - 10 = 10 - 10

4v² + 8v - 5 = 0

D = 8² - 4 · 4 · (-5) = 64 + 80 = 144

$v_{1} =\dfrac{-8-\sqrt{144} }{2 \cdot 4} =\dfrac{-8-12 }{8} =\dfrac{-20}{8} =-2.5\\\\v_{2} =\dfrac{-8+\sqrt{144} }{2 \cdot 4} =\dfrac{-8+12 }{8} =\dfrac{4}{8} =0.5\\\\$
