Gary learned that the value of his car depreciates by 15% percent per year. Which of the following functions best describes the

Sever21 [200]

For this case we have that the original value of the car is:
m dollars
For the following year we have the value is:
((100-15) / (100)) m
Rewriting we have:
((85) / (100)) m
0.85m
Answer:
the value of his car the year after the car is worth m dollars is:
B.f (m) = 0.85m

Quadratic equation whose vertex is (2,3) and y intercept is 11

never [62]

Answer:

y = 2(x - 2)² + 3 vertex form

y = 2x² - 8x + 11 standard form

Step-by-step explanation:

Vertex form

y = a(x - h)² + k

(h, k) = (2, 3)

y = a(x - 2)² + 3

To find "a" plug in the y-intercept (0, 11)

11 = a(-2)² + 3

11 = 4a + 3

Subtract 3 from both sides

8 = 4a

a = 2

y = 2(x - 2)² + 3

Expand

y = 2(x² - 4x + 4) + 3

y = 2x² - 8x + 11

What is a pair of irrational numbers whose difference is 0?

Mandarinka [93]

Answer:

When the difference of two numbers is zero, it means that the two numbers are the same.

Therefore, any irrational number substracted by itself will be equal to zero.

Here some examples:

√8 - √8 = 0
√1.6 - √1.6 = 0
π - π = 0

See "intersecting secants theorem" (you should be able to find a variant that specifically applies to arc measures). It says that for this circle,

$30^\circ=\dfrac{x-40^\circ}2\implies x=100^\circ$
