The value of a rare painting has increased each year since it was found at a garage sale. The value of the painting is modeled b

solmaris [256]

799 represents the initial value of the painting

The painting will be worth $926 after 5 years to the nearest dollar

Step-by-step explanation:

The form of the exponential function is $f(x)=a(b)^{x}$ , where

a is the initial value ⇒ (at x = 0)
b is the growth/decay factor ⇒ (rate of change)
If b > 1, then the function is growth ⇒ (increasing)
If 0 < b < 1, then the function is decay ⇒ (decreasing)

The value of a rare painting has increased each year since it was

found at a garage sale

The value of the painting is modeled by the function $f(x)=799(1.03)^{x}$

We need to know what 799 represents and what the painting will

be worth after 5 years

∵ $f(x)=799(1.03)^{x}$

∵ The form of the function is $f(x)=a(b)^{x}$

- By comparing the two forms

∴ a = 799 and b = 1.03

∵ a is the initial value at x = 0

∴ 799 represents the initial value of the painting

∵ x represents the number of years

∴ x = 5

- Substitute the value of x in the function by 5

∵ $f(5)=799(1.03)^{5}$

∴ f(x) = 926.26

∴ The painting will be worth $926 after 5 years to the nearest dollar

799 represents the initial value of the painting

The painting will be worth $926 after 5 years to the nearest dollar

Establish each identity:<br> csc Θ/ 1+ csc Θ = 1-sin Θ/ cos^2 Θ

shtirl [24]

$sin^2(\theta)+cos^2(\theta)=1\implies cos^2(\theta)=1-sin^2(\theta) \\\\[-0.35em] \rule{34em}{0.25pt}$

$\cfrac{csc(\theta )}{1+csc(\theta )}=\cfrac{1-sin(\theta )}{cos^2(\theta )} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{csc(\theta )}{1+csc(\theta )}\implies \cfrac{~~\frac{1}{sin(\theta )} ~~}{1+\frac{1}{sin(\theta )}}\implies \cfrac{~~\frac{1}{sin(\theta )} ~~}{\frac{sin(\theta )+1}{sin(\theta )}}\implies \cfrac{1}{sin(\theta )}\cdot \cfrac{sin(\theta )}{sin(\theta )+1}$

$\cfrac{1}{sin(\theta )+1}\implies \cfrac{1}{1+sin(\theta )}\implies \stackrel{\textit{multiplying by the conjugate of the denominator}}{\underset{\textit{difference of squares}}{\cfrac{1}{1+sin(\theta )}\cdot \cfrac{1-sin(\theta )}{1-sin(\theta )}}} \\\\\\ \cfrac{1-sin(\theta )}{1^2-sin^2(\theta )}\implies \cfrac{1-sin(\theta )}{1-sin^2(\theta )}\implies \cfrac{1-sin(\theta )}{cos^2(\theta )}$

Solve each inequality <br> 3m-2-2m>-5

motikmotik

3m - 2 - 2m > -5

First, simplify 3m - 2 - 2m to m - 2. / Your problem should look like: m - 2 > -5
Second, add 2 to both sides. / Your problem should look like: m > -5 + 2
Third, simplify -5 + 2 to -3. / Your problem should look like: m > -3

Answer: m > -3
