0=4t-16t^2 Solve this please

vaieri [72.5K]

Answer:

$\large\boxed{t=0\ \vee\ t=\dfrac{1}{4}}$

Step-by-step explanation:

$4t-16t^2=0\qquad\text{divide both sides by 4}\\\\\dfrac{4t}{4}-\dfrac{16t^2}{4}=\dfrac{0}{4}\\\\t-4t^2=0\\\\t(1-4t)=0\iff t=0\ \vee\ 1-4t=0\\\\1-4t=0\qquad\text{subtract 1 from both sides}\\\\-4t=-1\qquad\text{divide both sides by (-4)}\\\\t=\dfrac{1}{4}$

Find the value of x - if x^3-7x² - x = 0<br>a) 17 (b) 71 c) 7<br>d) 1

S_A_V [24]

Answer:

x = 0

Step-by-step explanation:

$x^3-7x^2-x =0\\$

Take out common factor

$x(x^2-7x-1) = 0$

The factor inside the parenthesis cannot be factored

Since there is a common factor that we pulled out of the original equation,

set that x equal to zero and solve

$x = 0\\$ : Therefore x = 0

John received $300 for his birthday he buys 4 DVDs at $12.95 each. Sales tax is 6.5% how much birthday money does he have left

joja [24]

Answer: $244.83

Step-by-step explanation:

First find the original amount spent on dvds:

$12.95 * 4 = $51.80

Then, the sales tax (6.5% is converted to decimal form by dividing by 100):

$51.80 * 0.065 = $3.367

Add the sales tax to the original amount to get the total amount spent:

$51.80 + $3.367 = $55.167

Round to the nearest hundredth:

$55.167 -> $55.17

Subtract the total amount from the money received for his birthday:

$300 - $55.17 = $244.83
