Answer:

Step-by-step explanation:

We use the Pythagorean theorem.

a^2 + b^2 = c^2

7^2 + 12^2 = 49 + 144 = 193

13^2 = 169

Since 193 is not equal to 169, the triangle is not a right triangle.

Answer:

$\$272,49$

Step-by-step explanation:

7. $\displaystyle /text{The answer makes sense because since the depreciation rate is 15%, we know that we need to use the "exponential decay" formula.}$

6. $\displaystyle /text{After a depreciation rate of 15% for the past 8 years, the stock is now worth approximately $272,49.}$

5. $\displaystyle 1000[0,85]^8 = 272,490525 ≈ \$272,49$

4. $\displaystyle 1000 = a \\ -15\% + 100\% = 1 - r; 85\% = 1 - r \\ 8\:years = time\:[t]$

3. $\displaystyle /text{We need to use the "Exponential Decay" formula} - f(t) = a[1 - r]^t, where a > 0$

2. $\displaystyle /text{How much is the stock worth after a depreciation rate of 15% per year?}$

1. $\displaystyle /text{initial amount: $1000, a depreciation rate of 15%, and a time period of 8 years}$

I am joyous to assist you anytime.

What is the solution to this problem (1,3)(5,k) m=2

Mazyrski [523]

Answer:

The solution of given problem is k = 11

Step-by-step explanation:

<u>slope of given two points formula:-</u>

slope m = $\frac{y_{2}- y_{1} }{x_{2}-x_{1} }$ .....(1)

Given points are (1,3) and (5,k)

given slope m = 2

now substituting m =2 and the given points are (1,3) and (5,k)

$2 = \frac{k-3}{5-1}$

on simplification we get solution

$k-3 = 8$

$k = 8 +3$

$k = 11$
