Will the solutions to the equation 12x2-5x-2=0 be positive or negative and how would you know without solving the equation compl

SOVA2 [1]

For this case we have the following equation:
12x2-5x-2 = 0
Using the resolver we have:
x = (- b +/- root (b ^ 2 - 4 * a * c)) / (2 * a)
Substituting values we have:
x = (- (- 5) +/- root ((- 5) ^ 2 - 4 * 12 * (- 2))) / (2 * 12)
Rewriting:
x = (5 +/- root (25 +96))) / (2 * 12)
x = (5 +/- root (121))) / (2 * 12)
x = (5 +/- 11) / (2 * 12)
Answer:
One root is positive and another is negative.

Find the dy/dx from<br>y=3×^2+5×^4 -10<br>

Valentin [98]

I’m rewriting it into d/dx so it’s a bit faster for me
d/dx(3x^2+5x^4-10)
=d/dx(3x^2)+d/dx(5x^4)+d/dx(-10)
=6x+20x^3, which is your desired answer

The value of the TV is $1500. Its value decreases by 14% each year. (A) write a function that represents the value y (in dollars

Kazeer [188]

Answer:

Part A) $y=1,500(0.86)^t$

Part B) The monthly percent decrease is about 1.3%

Part C) The value of TV after 3 years is about $950

Step-by-step explanation:

Part A) write a function that represents the value y (in dollars) of the TV after t years.

we know that

The exponential decay function is given by

$y=a(1-r)^t$

where

y is the value in dollars of the TV

t is the number of years

a is the initial value

r is the rate of decay

In this problem we have

$a=\$1,500\\r=14\%=14/100=0.14$

substitute

$y=1,500(1-0.14)^t$

$y=1,500(0.86)^t$

Part B) Find the approximate monthly percent decrease in value

we know that

$1\ year=12\ months$

I can rewrite the variable t as

$\frac{1}{12}(12t)$

Rewrite the function as

$y=1,500(0.86)^{\frac{1}{12}(12t)}$

using Power of a Power Property

$y=1,500(0.86^{\frac{1}{12}})^{(12t)}$

$y=1,500(0.9875)^{(12t)}$

<em>Find the decay rate</em>

$1-r=0.9875\\r=1-0.9875\\r=0.0125=1.25\%$

therefore

The monthly percent decrease is about 1.3%

Part C) Graph of the function from part (a). Use the graph to estimate the value of TV after 3 years

we have

$y=1,500(0.86)^t$

using a graphing tool

see the attached figure

From the graph

For t=3 years

The value of y is approximate 950

therefore

The value of TV after 3 years is about $950
