Vilka [71]3 years ago

Answer:

Step-by-step explanation:

Sec B

1) 5p⁻³ = 8*5⁻²      

p⁻³  = 2³*5⁻²/5            

p⁻³ =2³*5⁻³             { 1/a^m = a^-m}

p⁻³ = 5⁻³ /2⁻³            {a^m = 1/a^-m}

p⁻³ = (5/2)⁻³

p= 5/2

2) 4x²  = 81

x²  = 81/4

x²  = 9² /2²

x²  =(9/2)²

x = 9/2

3) 9^x/3 =81

9^x/3 = 9^2

Comparing the powers, x/3 = 2

                                         x = 2*3 =6

  x = 6

The hypotenuse of a right triangle is √18 units. what are the lengths of the legs of the triangle? How many different answers ca
storchak [24]
Since a right triangle has special rules to it such that the hypotenuse squared equals the sum of the squares of the other 2 sides. In other words, if the hypotenuse = c, and the 2 smaller sides are a and b, then:
{c}^{2}  =  {a}^{2}  +  {b}^{2}
Solving for c (hypotenuse), we get:
\sqrt{({c}^{2})} =   \sqrt{({a}^{2}+{b}^{2} )} \\ c =  \sqrt{({a}^{2}+{b}^{2} )}
Therefore c is the root of the square of the other sides. So by having root18, it's like saying:
\sqrt{18} =  \sqrt{({a}^{2}  +  {b}^{2} )}  \\ 18 = {a}^{2}  +  {b}^{2}
Getting rid of the square root, so sides a and b must have their squares total 18:
the only squares < 18 are: 16 (4×4), 9 (3×3), 4 (2×2), and 1 (1×1)
of those above added in any order of two of them, only 16+4
18 = 17 + 1 -  -  >  \sqrt{17}  \: and \: 1 \\ 18 = 16 + 2 -  -  >  \sqrt{16} \: and \:  \sqrt{2}  \\ ... \: 4 \: and \:  \sqrt{2}  \\ 18 = 15 + 3 -  -  >  \sqrt{15} \:  and \:  \sqrt{3}
18 = 14 + 4 -  -  >  \sqrt{14} \:  and \:  \sqrt{4}  \\ ... \sqrt{14} \: and \: 2  \\ 18 = 13 + 5 -  -  >  \sqrt{13} \: and \:  \sqrt{5}   \\ 18 = 12+ 6 -  -  >  \sqrt{12} \:  and \:  \sqrt{6}
18 = 11 + 7 -  -  >  \sqrt{11} \:  and \:  \sqrt{7}  \\ 18 = 10 + 8 -  -  >  \sqrt{10} \:  and \:  \sqrt{8}  \\ ... \sqrt{10} \:  and \: 2 \sqrt{2}  \\ 18 = 9 + 9 -  -  >  \sqrt{9}  = 3 \: and \: 3
I HOPE THAT IS ALONG THE LINE THAT WAS ASKED FOR!!! :-D

tarik starts a morning walk at 7:00 am. his distance, in miles, to the nearby grocery store after x hours is f(x)
Grace [21]

Total distance walked by Tarik is 0.75 miles according to the given equation.

What is equation?

In arithmetic, an equation could be a formula that expresses the equality of 2 expressions, by connecting them with the sign =.

Main body:

Given that

The expression that represents the Tarik's distance is

=>  f(x) = 3∣x−0.5∣

And also given that at 7.15 am he is some distance away from the store

Let Tarik is 'a' miles away from the store at 7.15 am

The time taken to walk 'a' miles = 7.15 - 7.00 = 15 minutes

As we know 60 minutes = 1 hr

=> 15 minutes = 15/60 = 0.25 hrs  

The given expression to find the Distance is

f(x) = 3 ∣x − 0.5∣    where x is number of hours

At x = 0.25

f(0.25) = 3 |0.25 - 0.5|

= 3 |- 0.25|

= 0.75 miles

Therefore,Tarik is 0.75 miles away from the store.
