Answer:

[See Below]

Step-by-step explanation:

✦ With this information we can make an equation to solve for y(years).

  • The tree is 4 \frac{1}{2} feet already.
  • It's expected to grow 1 \frac{3}{4} feet per year.
  • We are trying to figure our how many years until it's 40 feet.

✦ So the equation would be:

  • 40 ÷ 1 \frac{3}{4} =y

✦ Turn the fractions into a decimals to make it easier:

  • 1 \frac{3}{4} =1.75

✦ Now Solve by Dividing:

  • 40 ÷ 1.75=22.8571429

✦ Round:

  • 22.8571429 rounded to the nearest tenth =22.9

So your answer would be \bold2\bold2\bold.\bold9 years.

BRAINLIESTTT ASAP! PLEASE HELP ME :)<br><br> Find the inverse of :
muminat

Answer:

h^{-1}(x) = \dfrac{5x - 6}{2}

Step-by-step explanation:

h(x)= \dfrac{2x + 6}{5}

(a) Rename h(x) as y  

y = \dfrac{ 2x+ 6}{5}

(b) Solve for x :  

\begin{array}{rcl}y& = &\dfrac{2x + 6}{5}\\\\5y & = & 2x + 6\\5y - 6 & = & 2x\\x & = & \mathbf{\dfrac{5y - 6}{2}}\end{array}

(d) Switch x and y  

y = \dfrac{5x -6}{2}

(e) Rename y as the inverse function  

h^{-1}(x) = \mathbf{\dfrac{5x - 6}{2}}

The graphs of inverse functions are reflections of each other across the line y = x.

In the diagram, the graph of h⁻¹(x) is the reflection of h(x) about the line y = x.

Use the method of completing the square to transform the quadratic equation into the equation form (x + p)2 = q. 3 + x - 3x2 = 9
Triss [41]
To <span>transform the quadratic equation into the equation form (x + p)2 = q we shall proceed as follows:
3+x-3x^2=9
putting like terms together we have:
-3x^2+x=6
dividing through by -3 we get:
x^2-x/3=-2
but
c=(b/2a)^2
c=(-1/6)^2=1/36
thus the expression will be:
x^2-x/3+1/36=-2+1/36
1/36(6x-1)</span>²=-71/36

the answer is:
1/36(6x-1)²=-71/36
