In physics, it is important to use mathematical approximations. for instance, in a small angle approximation, tanα ∼ sin α . fin

siniylev [52]

Note that x is measured in radians.
The percent difference or error between sin(x) and tan(x) is calculated as
$d = 100( \frac{|sin(x)-tan(x)|}{sin(x)} )$

We want this percent difference to be less than 10.4%.
Because tan(x) > sin(x) for small values of x, define
$f(x) = \frac{tan(x)-sin(x)}{sin(x)}= 0.104 \\ or \\ sec(x) - 1 = 0.104 \\ sec(x) = 1.104$

From the calculator, obtain
sec⁻¹ 1.104 = 0.4375

Answer: x = 0.4375 radians

I need help simplify: 4^8/4^-4

LenKa [72]

Answer:

$4^{12}$

Step-by-step explanation:

using the rule of exponents

$\frac{a^{m} }{a^{n} }$ = $a^{(m-n)}$ , then

$\frac{4^{8} }{4^{-4} }$ = $4^{(8-(-4))}$ = $4^{(8+4)}$ = $4^{12}$

A person earns $187.42 before deductions for 3 days' work. What is the rate of pay per hour assuming 8 hours of work per day?

gavmur [86]

8 hours = 1 day

24 hours = 3 days

187.42/24

Round it up and it will give you $7.80/hour

The given lengths are two sides of a right triangle. All three side lengths of the triangle are integers and together form a pyt

Leni [432]

If all three side lengths are INTEGERS and form PYTHAGOREAN TRIPLE then we know decimals are not allowed

if 24 and 51 are both legs then
$24^{2} + 51^{2} = x^{2}$
x = 3177
and squre root of that gives us 56.364.... NOT an integer

So that means one of them is not a leg and since hypotenuse is longer than both legs, 51 must be the hypotenuse so to get the third side

$51^{2} - 24^{2} = x^{2}[tex] [tex] x^{2}$ =2025
x=45, leg B
