What’s is the inverse function of a(m)=0.6735e^0.423m
natta225 [31]

Answer:

a^{-1}(m)=\frac{ln(\frac{m}{0.6735})}{0.423}

Step-by-step explanation:

The function is  a(m)=0.6735e^{0.423m}

Changing functional notation of a(m) to y:

y=0.6735e^{0.423m}

Now, interchanging m and y:

m=0.6735e^{0.423y}\\

Now, solving for y:

e^{0.423y}=\frac{m}{0.6735}\\ln[e^{0.423y}]=ln[\frac{m}{0.6735}]\\0.423y=ln(\frac{m}{0.6735})\\y=\frac{ln(\frac{m}{0.6735})}{0.423}

Thus, the inverse function is:

a^{-1}(m)=\frac{ln(\frac{m}{0.6735})}{0.423}

What is the next number in the following series: 54, 49, 44, 39, ...
Damm [24]

<em>Hello there! And thank you for asking your question here on brainly . com! The number one asking and answering site.</em>

Answer: C. 34

Explanation: The series shown is reducing by 5 digits. 54 - 5 = 49, 49 - 5 = 44, and so on. When we're at 39, just subtract by 5. 39 - 5 = 34. 34 is the answer.

Hope this helped you, and have an awesome day! ☺♥

Answer this question please and I will give brainliest
erik [133]

Answer:

Jordan

Step-by-step explanation:

Because each person is in debt the one with the least amount of dept will pay less. Think of it like this:

You owe the bank 85 dollars so your account balance is -85 since you owe money

if you were to owe 100 dollars then you owe more money.

Therefore owing 85 dollars is the least amount of money owed in this case

Verify that [tan(theta) + cot(theta)]^2 = sec^2(theta) + csc^2(theta)
Wittaler [7]

(tanθ + cotθ)² = sec²θ + csc²θ

<u>Expand left side</u>: tan²θ + 2tanθcotθ + cot²θ

<u>Evaluate middle term</u>: 2tanθcotθ = 2*\frac{sin\theta}{cos\theta}*\frac{cos\theta}{sin\theta} = 2

⇒ tan²θ + 2+ cot²θ

= tan²θ + 1 + 1 + cot²θ

<u>Apply trig identity:</u>  tan²θ + 1 = sec²θ

⇒ sec²θ + 1 + cot²θ

<u>Apply trig identity:</u>  1 + cot²θ = csc²θ

⇒ sec²θ + csc²θ

Left side equals Right side so equation is verified
