Answers

Answer 1

Answer: The base is 8 and the height is 8.
8x8 = 64
64 divided by 2 is 32
The area is 32 ft squared

I got this answer by using the formula for finding the area of a triangle. Base x height divided by 2

What is the simplified form of the quantity of x plus 8, all over the quantity of x plus 2 + the quantity of x minus 3, all over 4?

Answers

Answer: $(x^2+3x+26)/(4x+8)$

Step-by-step explanation:

Since, according to the question the given expression,

$(x+8)/(x+2) + (x-3)/(4)$

= $(4(x+8)+(x-3)(x+2))/(4(x+2))$

= $(4x+32+(x-3)(x+2))/(4x+8)$ (By solving the parenthesis )

= $(4x+32+x(x+2)-3(x+2))/(4x+8)$ ( by distributive property)

= $(4x+32+x^2+2x-3x-6)/(4x+8)$ ( again on applying distributive property)

= $(3x+26+x^2)/(4x+8)$ ( by operating like terms)

= $(x^2+3x+26)/(4x+8)$

$(x + 8)/(x + 2) + (x - 3)/(4) = (4(x + 8))/(4(x + 2)) + ((x + 2)(x - 3))/(4(x + 2)) = (4(x) + 4(8))/(4(x + 2)) + (x(x - 3) + 2(x - 3))/(4(x + 2)) = (4x + 32)/(4(x + 2)) + (x(x) - x(3) + 2(x) - 2(3))/(4(x + 2)) = (4x + 32)/(4(x + 2)) + (x^(2) - 3x + 2x - 6)/(4(x + 2)) = (4x + 32)/(4(x + 2)) + (x^(2) - x - 6)/(4(x + 2)) = ((4x + 32) + (x^(2) - x - 6)/(4(x + 2)) = (x^(2) + (4x - x) + (32 - 6))/(4(x + 2)) = (x^(2) + 3x + 26)/(4(x + 2))$

A boat costs $12,050 and decreases in value by 12% per year. How much will the boat be worth after 9 years?A $33,415.60
B $3,813.56
C $11,942.00
D $3,355.94

Answers

B $3,813.56 is the correct answer

1 year = $10,604
2 years = $9,331.52
3 years = $8,211.74
4 years = $7,226.33
5 years = $6,359.17
6 years = $5,596.07
7 years = $4,924.54
8 years = $4,333.60
9 years = $3,813.56

For this case we have the following expression:

$y = A (b) ^ x$

Where,

A: initial value
b: rate of change
x: number of years
y: future value

Therefore, replacing values we have:

$y = 12050 * (0.88) ^ 9\ny = 3813.56$

Answer:

The boat will be worth after 9 years about:

B $ 3,813.56
