Answer:

<em>Conner's work is correct</em>

Step-by-step explanation:

<u>Operations With Exponents</u>

We need to use the rule to find the product of two or more exponential expressions:

x^m\cdot x^n\cdot x^p = x^{m+n+p}

We need to multiply:

(3^5 6^8)(3^9 6^{10})

Base 3 is treated independently from base 6, so we have two groups of operations:

(3^5 6^8)(3^9 6^{10})=3^{5+9} 6^{8+10}

Adding the exponents:

(3^5 6^8)(3^9 6^{10})=3^{14} 6^{18}

Thus, Conner's work is correct

Pure acid is to be added to a 10% acid solution to obtain 90L of 81% solution. What amounts of each should be used?
Vlada [557]

Answer:

Step-by-step explanation:

let X be the quantity of 100% acid

let Y be the quantity of  10% acid

X + Y = 90

Y = 90 - X

         X(100) + Y(10) = 90(81)

X(100) + (90 - X)(10) = 90(81)

   100X + 900 - 10X = 7290

                         90X = 6390

                              X = 71 L

The table shows a linear relationship between x and y. What is the rate of change of y with respect to x.
ella [17]

Answer:

A. -⁹/2

Step-by-step explanation:

Using any two pairs of values form the table, say (-12, 60) and (-6, 33),

Rate of change = ∆y/∆x

= (33 - 60) / (-6 -(-12))

= -27/6

= -9/2

Rate of change = -⁹/2

Find the sum of 1st 18 terms of an AP whose nth term is 3-2n.
cricket20 [7]

Answer:

-288

Step-by-step explanation:

<h3>Given AP</h3>
  • t(n) = 3 - 2n

<u>To find,</u>

  • The sum of first 18 terms
<h3>Solution</h3>
  • Sn = 1/2n(t(1) + t(n))

<u>The first and 18th terms as per the formula</u>

  • t(1) = 3 - 2 = 1
  • t(18) = 3 - 18*2 = 3 - 36 = -33
  • S18 = 1/2*18(1 - 33) = 9*(-32) = -288

<u>Answer is</u> -288

Solve the following equation by completing the square. 12x^2 - 48x = -39​
daser333 [38]

Answer:

\large\boxed{\boxed{x = \begin{cases} \frac{ \sqrt{3} }{2}  + 2 \\     - \frac{ \sqrt{3} }{2}  + 2 \end{cases}}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • quadratic equation
  • PEMDAS
<h3>let's solve:</h3>
  1. \sf divide \: both \: sides \: by \: 12 :  \\  \sf  {x}^{2}  - 4x =  -  \frac{13}{4}
  2. \sf \: add  \: { -  2}^{2}  \: to \: both  \: sides :  \\  \sf  { {x}^{2} } - 4x + ( -  {2}^{2} ) =  \frac{13}{4}  + (  { - 2}^{2} ) \\  {x}^{2}  - 4x  + 4 =  \frac{13}{4}  + 4
  3. \sf simplify \: addition :  \\  \sf  { {x}^{2} } - 4x + 4 =  \frac{3}{4}
  4. \sf use \:  {a}^{2}  - 2ab +  {b}^{2}  = (a - b {)}^{2}  :  \\  \sf (x - 2 {)}^{2}  =  \frac{3}{4}
  5. \sf squre \: root \: both \: sides :  \\  \sf  \sqrt{(x - 2 {)}^{2} }  =  \pm \sqrt{ \frac{3}{4} }  \\ \begin{cases} x  - 2 =  \frac{ \sqrt{3} }{2}  \\x - 2 =  -  \frac{ \sqrt{3} }{2}  \end{cases}
  6. \sf add  \: 2 \: to \: both \: sides :  \\  \sf  \begin{cases}x =  \frac{ \sqrt{3} }{2}  + 2 \\  x =   - \frac{ \sqrt{3} }{2}  + 2 \end{cases} \\  \therefore \: x =  \begin{cases} \frac{ \sqrt{3} }{2}  + 2 \\     - \frac{ \sqrt{3} }{2}  + 2 \end{cases}
