Answer:

Solutions are x = 6.46 and 1.04

Step-by-step explanation:

The given quadratic equation is 4x² - 30x + 45 = 0

We have to find the solutions of the equation.

Now we will use the formula of quadratic equations

x=\frac{30\pm \sqrt{900-16\times 45}}{8}

=\frac{30\pm \sqrt{500}}{8}

=\frac{30\pm 22.36}{8}

x=6.46

Or x=1.04

You would solve for x by finding a, b, and c of the quadratic the you would use the quadratic formula. You should get x=\frac{15+-3 \sqrt{5} }{4} and x~ 5.427

A race car is driven around a circular track at a constant speed of 180 miles per hour. If the diameter of the track is 1/2 mile
velikii [3]
F the diameter is 1/2 mile, that is 0.5 mile, then the radius is 0.25 -half of it!

the angular speed is theta/time, which means

 w=theta/time

but another formula for it is Velocity*radians

w=velocity*radians

velocity is 180 mph and radians are (revolution/2 radius), that is:

w=180*(1/2*0.25)
and if we calculate this, we have: w=114.59, which is the correct answer!

A sample of bacteria is decaying according to a half-life model. If the sample begins with 700 bacteria, and after 10 minutes th
Papessa [141]

Answer:

18 minutes

Step-by-step explanation:

A = A₀ (½)^(t / T)

where A is the final amount,

A₀ is the initial amount,

t is the time,

and T is the half life.

A = 140 when t = 10.  Solve for the half life:

140 = 700 (½)^(10 / T)

0.2 = ½^(10 / T)

log 0.2 = (10 / T) log 0.5

10 / T = 2.32

T = 4.31

When A = 40, t is:

40 = 700 (½)^(t / 4.31)

0.057 = ½^(t / 4.31)

log 0.057 = (t / 4.31) log 0.5

t / 4.31 = 4.13

t = 17.8

Rounded to the nearest whole number, it takes 18 minutes.

2 = (-x) Help I'm a not so bright blonde!
makvit [3.9K]
If you need to solve this equation you can multiply the both side of equation on (-1). Like that
<span>2 = (-x);
-1·2 = (-1)·(-x)
if you multiply negative and </span><span>positive </span>you'll have negative,
if you multiply negative and <span>negative you'll have </span><span><span>positive. So
</span> 
</span>-2 = x.  or
x = -2.
The answer is -2.
