Answer: Irrational numbers

Step-by-step explanation: Let's take a look at the decimal 94.340192... which is an example or an irrational number.

Notice that this decimal is both non-terminating which means it has no repeating digits and a definite end and non-repeating which means that 1 or more numbers repeat so this decimal would be an irrational number.

a stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where s(t) = 4.9t^2 + 29.

Alenkinab [10]

Answer:

t = 9 s

Step-by-step explanation:

A stone is thrown downward with an intitial velocity of 29.5 m/sec will travel a distance of a meters, where

$s(t) = -4.9t^2 + 29.4+132.3$

We need to find when the stone will hit the ground. It means when s(t) = 0. So,

$-4.9t^2 + 29.4t+132.3=0\\\\t=-3\ and\ t=9$

So, the stone will take 9 seconds to hit the ground. Hence, this is the required solution.

Can someone kindly answer number 4?

ch4aika [34]

X = list price = price before discount

15% is the discount, ie, we take 15% of x and subtract it off the original price

final price = (original price) - (15% of original price)
final price = x - 15% of x
final price = x - 0.15x
final price = 0.85x

The final price (or sale price) is $722.50, therefore

0.85x = 722.50
0.85x<span>/0.85</span> = 722.50/0.85
x = 850

The laptop was originally $850

Final Answer: 850

In triangle opq right angled at p op=7cm,oq-pq=1 determine the values of sinq and cosq

soldi70 [24.7K]

Answer:

see explanation

Step-by-step explanation:

let pq = x

given oq - pq = 1 then oq = 1 + x

Using Pythagoras' identity, then

(oq)² = 7² + x²

(1 + x)² = 49 + x² ( expand left side )
