For me it is somethimes Because if th base 1 and base 2(which is always not congruent) can form a square, then if u draw a line with it then u can make right triangle with same sides which can use as a 45 45 90 or 30 60 90. Hope is helps

Answer correctly please

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: $1000, a depreciation rate of 15%, and a time period of 8 years}$

-2x^2+5x-4=0 , find the discriminant

BaLLatris [955]

Answer:

The discriminant is -7

Step-by-step explanation:

The discriminant of a quadratic function/equation(ax^2+bx+c = 0) is calculated as:

$b^2 -4ac$

Here

b is the co-efficient of x

a is the co-efficient of x^2

and c is the constant

Given equation is:

$-2x^2+5x-4=0$

Here

a = -2

b = 5

c = -4

Putting the values in the formula for discriminant

$= b^2 - 4ac\\= (5)^2 - 4(-2)(-4)\\= 25 - 32\\=-7$

As the discriminant is negative, the equation has no real solution.

Hence,

The discriminant is -7

Albert drew a scale drawing of a county park. The scale he used was 7 inches : 4 yards. The actual width of the picnic area is 6

Elenna [48]

I think its like you divide 64 by 4. This will tell you how many sets of the 4 yards you have which is important to know since each 4 yards equals 7 inches. 64 divided by 4 is 16. Then multiple 16 by 7 since there's 16 sets of 4 and each set is 7 inches. This will come to a total of 112 inches.

I hope this helps, sorry if its wrong I haven't done this in a while, but I'm pretty sure its correct
