Answer:

a = 36

Step-by-step explanation:

A stationary point is where the function derivative is zero. Here, we have ...

y' = 2kx -16/x^2 = 0

For x = 2/3, this is ...

4/3k -16/(4/9) = 0

4/3k = 36

k = 27

Then the value of y at that point is ...

y = 27(2/3)^2 + 16/(2/3) = 12 +24 = 36

The stationary point of interest is (2/3, a) = (2/3, 36). a = 36.

What is the average rate of change for the sequence shown below?

Mkey [24]

Hey There!

To find the rate of change, simply use the following formula.

y2 - y1 = x2 - x1

Keeping this in mind, let's begin to solve.

3 - 4 = -1

1 - (-1) = 2

Therefore, the answer would be C

Solve the equation to find where the treste ground levelEnter your answers from least to greatest and round to the nearest The m

DaniilM [7]

Answer:

The trestle meets ground level at 0.875 units and 9.125 units

Step-by-step explanation:

Poorly formatted question.

The given equation is:

$y = -x^2 + 10x - 8$

Required

The point where the trestle gets to the ground level

To do this, we set $y = 0$

So, we have:

$-x^2 + 10x - 8 = 0$

Multiply through by -1

$x^2 -10x + 8 = 0$

Solve using quadratic formula:

$x= \frac{-b \± \sqrt{b^2 - 4ac}}{2a}$

Where:

$a = 1; b =-10; c = 8$

So, we have:

$x= \frac{-(-10) \± \sqrt{(-10)^2 - 4*1*8}}{2*1}$

$x= \frac{-(-10) \± \sqrt{68}}{2*1}$

$x= \frac{-(-10) \± 8.25}{2}$

$x= \frac{10 \± 8.25}{2}$

Solve the fraction

$x= 5 \± 4.125$

Split

$x= 5 + 4.125\ or\ x= 5 - 4.125$

$x= 9.125\ or\ x= 0.875$

Answer:a) $5.64 b) 21 ounces of tea leaves

Step-by-step explanation:

Step 1

5 ounces of tea leaves can be bought with $2.35

1 ounce of tea can be bought with =$2.35/5 =$0.47

12 ounces at the same rate can be bought with

=12 x $0.47 = $5.64

b) 5 ounces of tea leaves can be bought with $2.35

? Ounces of tea leaves can be bought with $10

$2.35 =5 ounces of tea

$10 = ? ounces of tea

= (10 x 5)/2.35

=50/2.35

=21.27 rrounded to 21 ounces of tea leaves
