Given that (0,3) is on the graph of f(x), find the corresponding point for the function f(x)-2
natima [27]

Answer:

(0 , 1)

Step-by-step explanation:

given y = f(x), then

y = f(x) + c is a vertical translation

• If c > 0 then vertical shift up of a units

• If c < 0 then vertical shift down of a units

here c = - 2, hence shift down of f(x) by 2 units

(0, 3) → (0, 3 - 2 ) = (0, 1)

Part A:The area of a square is (25x2 − 40x + 16) square units. Determine the length of each side of the square by factoring the
Artyom0805 [142]

Answer:

see explanation

Step-by-step explanation:

A

25x² - 40x + 16 ← is a perfect square of the form

(ax - b)² = a²x² - 2abx + b²

Comparing the coefficients of like terms in the 2 expressions

a² = 25 ⇒ a = 5, b² = 16 ⇒ b = 4

and 2 × 5 × 4 = 40, thus

25x² - 40x + 16 = (5x - 4)²

The side of the square = 5x - 4

B

25x² - 16y² ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b), thus

25x² - 16y²

= (5x)² - (4y)² = (5x - 4y)(5x + 4y)

Dimensions of rectangle are 5x - 4 and 5x + 4

Shkiper50 [21]

Answer: Search Results

Featured snippet from the web

In triangle sum of 2 sides must be greater than the 3rd side. So, the third > 8 - 6 = 2 and also the third < 8 + 6 = 14. So, the answer is 2 < third side < 14. The third side lies between(2,14).
