Answer:

  Exponential Decay

Step-by-step explanation:

The base of the exponential term is less than 1, so the function represents decay.

Answer:7

Step-by-step explanation:

This question is on the ukmt junior maths challenge which I'm doing now, out of the options given I got 7, because 2+4+6+5+(5×20)+(7×7)= 166, (then dividing that by the number of numbers to get the mean) so 166÷31= 5.354.....

Also the 3 has a recurring symbol above it

The 7 is times seven so uh yeah<3

The smallest possible value of 'q' is 7 and this can be determined by using the hit and trial method and mean formula.

Given :

The following steps can be used in order to determine the smallest possible value of q:

Step 1 - The formula of the mean can be used in order to determine the smallest possible value of q.

Step 2 - The mean of all the numbers is given by:

[tex]\rm \dfrac{2+4+6+5+5p+7q}{6+p+q}=5.3[/tex]

[tex]\rm \dfrac{21 + 5p + 7 q}{6+p+q} = 5.3[/tex]

Step 3 - So, by the hit and trial method, the value of q can be determined.

Therefore, the value of 'q' is 7.

Coins, heads, or tails are the practice of flinging a coin through into the air and checking what side shows whenever it lands, to choose between two possibilities, heads or tails, that are occasionally used for trying to settle conflicts between different parties.

Total outcomes: [tex]\bold{2 \times 5 \times 6 = 60}[/tex]

Answer:

$2.95 sales tax. $61.95

Step-by-step explanation:

Answer:

$61.95

Step-by-step explanation:

First find the amount of sales tax.

59 times .05= 2.95

Sales tax is $2.95, because 5% is written as .05 as a decimal. .05 times 59 gives us how much money 5% of $59 is.

Now add that to the original price!

59+2.95= 61.95

So our final price is $61.95

Hope this helps!

Step-by-step explanation:

Area:=45

Answer:

(a) The constant of proportionality is 0.25

(b) 1 apple = $0.25

(c) $3 = 12 apples

Step-by-step explanation:

Given

[tex]c= 0.25n[/tex]

Solving (a): The constant of proportionality;

For an equation:

[tex]c=kn[/tex]

Where

k = constant of proportionality

By comparing: [tex]c=kn[/tex] to [tex]c= 0.25n[/tex]

[tex]k = 0.25[/tex]

Hence, the constant of proportionality is 0.25

Solving (b): What information does [tex]k = 0.25[/tex] gives.

It represents the unit rate.

So, it means that 1 apple costs $0.25

Solving (c): Number of apples for $3.

This means that [tex]c = 3[/tex]

Substitute 3 for c in [tex]c= 0.25n[/tex]

[tex]3 = 0.25n[/tex]

Make n the subject

[tex]n = \frac{3}{0.25}[/tex]

[tex]n = 12[/tex]

Answer:

[tex]\dfrac{1}{\sqrt{42}}(i+4j-5k)[/tex] and [tex]-\dfrac{1}{\sqrt{42}}(i+4j-5k)[/tex]

Step-by-step explanation:

The two vectors are

[tex]a=i+j+k[/tex]

[tex]b=5i+k[/tex]

Unit vector is given by

[tex]\dfrac{a\times b}{|a\times b|}[/tex]

[tex]a\times b=\begin{vmatrix} i & j & k\\1 & 1 & 1\\5 & 0 & 1\end{vmatrix}\\ =i(1-0)-j(1-5)+k(0-5)\\ =i+4j-5k[/tex]

[tex]|a\times b|=\sqrt{1^2+4^2+(-5)^2}=\pm\sqrt{42}[/tex]

[tex]\dfrac{a\times b}{|a\times b|}=\dfrac{i+4j-5k}{\sqrt{42}}\\\Rightarrow \dfrac{a\times b}{|a\times b|}=\pm\dfrac{1}{\sqrt{42}}(i+4j-5k)[/tex]

The two unit vectors that are orthogonal to both given vectors is [tex]\dfrac{1}{\sqrt{42}}(i+4j-5k)[/tex] and [tex]-\dfrac{1}{\sqrt{42}}(i+4j-5k)[/tex].

g¹(1) =  [tex]\frac{1}{6}[/tex]

The inverse of the  function   [tex]g(x) = \frac{x^{\frac{1}{3} }-1 }{2}[/tex]

Step-by-step explanation:

Step(i):-

Given that f(x) = (2x+1)³

 Let  y =  (2x+1)³

       [tex]y^{\frac{1}{3} } =2x+1[/tex]

      [tex]2x = y^{\frac{1}{3} } -1[/tex]

       [tex]x = \frac{y^{\frac{1}{3} }-1 }{2}[/tex]

Step(ii):-

y = f(x) ⇒  x = f⁻¹ (y)

  ⇒ [tex]f^{-1} (y) = \frac{y^{\frac{1}{3} }-1 }{2}[/tex]

     [tex]f^{-1} (x) = \frac{x^{\frac{1}{3} }-1 }{2}[/tex]

The inverse of the given function  

        [tex]g(x) = \frac{x^{\frac{1}{3} }-1 }{2}[/tex]

Differentiating equation (i) with respective to 'x', we get

      [tex]g^{l} (x) = \frac{1}{2} X \frac{1}{3} x^{\frac{1}{3} -1}[/tex]

     [tex]g^{l} (x) = \frac{1}{6} x^{\frac{-2}{3} }[/tex]

Final answer:-

Put x=1

  [tex]g^{l} (1) = \frac{1}{6} 1^{\frac{-2}{3} } = \frac{1}{6}[/tex]
