What are two absolute value expressions that are equivalent to |7+9|.

arlik [135]

You did not give is choices to choose from.

|7 + 9| is the same as |-7 - 9|.

|16| is the we same as |-16|.

Which of the following is the graph of y = negative (x minus 2) cubed minus 5?

inysia [295]

Step-by-step explanation:

(x-2)^3 = x^3-6x^2+12x-8

-(x^3-6x^2+12x-8)=

-x^3+6x^2-12x+8

-x^3+6x^2-12x+8 -5=

y=-x^3+6x^2-12x+3

N(t) = 100,000e−(t − 10)2/8

mafiozo [28]

The approximation of the slope of the graph at t = 10 days using this secant lines are 11750 and -11750, respectively.

<h3>How to determine the slope of the secant lines?</h3>

<u>(a) t = 10 days and a day earlier</u>

This means that:

t = 10 and t = 9

The function is given as:

$N(t) = 100000e^{\frac{-(t - 10)^2}{8}}$

Calculate N(10)

$N(10) = 100000e^{\frac{-(10 - 10)^2}{8}}$

Evaluate

N(10) = 100000

Next, calculate N(9)

$N(9) = 100000e^{\frac{-(9 - 10)^2}{8}}$

Evaluate

N(9) = 88249.6902585

The slope is then calculated using"

$m = \frac{N(10) - N(9)}{10 - 9}$

This gives

$m = \frac{100000 - 88249.6902585}{10 - 9}$

Evaluate

m = 11750.3097415

Approximate

m = 11750

<u>(b) t = 10 days and a day later</u>

This means that:

t = 10 and t = 100

The function is given as:

$N(t) = 100000e^{\frac{-(t - 10)^2}{8}}$

In (a), we have:

N(10) = 100000

Next, calculate N(11)

$N(9) = 100000e^{\frac{-(11 - 10)^2}{8}}$

Evaluate

N(11) = 88249.6902585

The slope is then calculated using:

$m = \frac{N(11) - N(10)}{11 - 10}$

This gives

$m = \frac{88249.6902585 - 100000}{11 - 10}$

Evaluate

m = -11750.3097415

Approximate

m = -11750

Hence, the approximation of the slope of the graph at t = 10 days using this secant lines are 11750 and -11750, respectively.
