Answer:

Step-by-step explanation:

Using the Pythagorean's theorem,

DO²=DG²+GO²=3²+3²=2*3²

DO=3√2

JO=DO-DJ=3√2-3=3(√2-1)

If f(x) is a linear function, then

f(x) = ax + b

for some constants a and b.

Given that f (1) = 4 and f (4) = 1, these constants are such that

f (1) = a + b = 4

f (4) = 4a + b = 1

Solve for a and b : eliminate b by subtracting the two equations,

(a + b) - (4a + b) = 4 - 1

-3a = 3

a = -1

Then

-1 + b = 4

b = 5

So we have

f(x) = -x + 5

Answer:

Domain: (-∞,0) ∪ [0,∞)

Range: [-3,∞)

f(0) = -3

The domain of the function will be (-∞, 0) U [0, ∞).

The domain means all the possible values of x and the range means all the possible values of y.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The function is a piecewise function.

Use the graph of the function to find the domain of f.

From the graph, the domain of the function will be (-∞, 0) U [0, ∞).

More about the domain and range link is given below.

Answer:

42 ft, 60 ft, 84 ft

Step-by-step explanation:

let x be the shortest side , then the other 2 sides are 2x and x + 18, so

x + 2x + x + 18 = 186 , that is

4x + 18 = 186 ( subtract 18 from both sides )

4x = 168 ( divide both sides by 4 )

x = 42

Then lengths of sides are

x = 42 ft

2x = 2 × 42 = 84 ft

x + 18 = 42 + 18 = 60 ft

Answer:

4 _____ 9

the geometric sequence is the addition of 2.5 to every number until the specific amount you are to get

4+2.5=6.5 that is the second term

if I then add 2.5 to 6.5it will give me 9 which is the third term but we are asked to find the sum of the first 4terms so 9+2.5=11.5

if we are to add 4,6.5,9 and 11.5 it would give me =31 which is the final answer.

hope this helps.

Step-by-step explanation:

The length of the sidewalk is 25 + 4 + 4 = 33 ft

The width of the sidewalk is 4 ft

area of top/ bottom = 2(4 × 33) = 2 ×132 = 264 ft²

→ Note this area includes the 4 corners ←

area of 2 sides = 2(4 × 9) = 2 × 36 = 72 ft²

area of sidewalk = 264 + 72 = 336 ft² → D

The rate of change represented by the graph is that the car drives down the mountain at a rate of 250 feets per hour.

The rate of change also called the gradient or slope is obtained using the relation :

Rate of change = change in y / change in x

Change in y = (y2 - y1)

Change in x = (x2 - x1)

From the graph :

y2 = 1500 ; y1 = 0

y2 = 1500 ; y1 = 0x2 = 6 ; x1 = 0

Hence,

Rate of change = (1500 - 0) / (6 - 0) = 1500 / 6 = 250
