29) First of all when I write “^2” I mean to the power of 2. Label the bottom line Z or whatever u fancy. Then make 3 equations to solve simultaneously using a^2+b^2=c^2
(1) 14^2+y^2=Z^2
(2) 6^2+y^2=x^2 and (3) x^2+z^2=20^2
The next step is to solve them simultaneously e.g you can rearrange (2) to give you y^2=x^2-6^2 and then input that into (1) to get 14^2+x^2-6^2=Z^2 and again you rearrange (3) to get z^2=20^2-x^2 and input that in and solve for x. Then you will have to repeat that solving for y and only y as the question doesn’t originally ask for z but only for the values of x and y I assume. Using this idea, from glancing at the other questions you should be able to apply this concept to those other questions, if not then make another post outlining any specific questions
Answer:
3999999999/100000000
Step-by-step explanation:
To write 39.99999999 as a fraction you have to write 39.99999999 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
39.99999999 = 39.99999999/1 = 399.9999999/10 = 3999.999999/100 = 39999.99999/1000 = 399999.9999/10000 = 3999999.999/100000 = 39999999.99/1000000 = 399999999.9/10000000 = 3999999999/100000000
f(x) = 2|-4x + 5| - 4
Solution to Example 3
<span><span><span>The range of |-4x + 5| is given by
|-4x + 5| ≥ 0
</span><span>Multiply both sides of the inequality by 2 to obtain
2 |-4x + 5| ≥ 0
</span><span>Add -4 to both sides of the above inequality to obtain
2 |-4x + 5| - 4 ≥ - 4
</span></span><span>The range of 2 |-4x + 5| - 4 may also be written in interval form as follows
[-4 , ∞)</span></span><span>The domain of f above is the set of all values of x in the interval ( -3 , +∞)
