Answer:

Step-by-step explanation:

graphs above x-axis are positive and below are negative.

(b). A(+), B(+), C(-),D (-)

A=(3-0)/(1-0)=3

B=(1-0)/(2-0)=1/2

C=(-6-0)/(1-0)=-6

D=(-1-0)/(4-0)=-1/4

(c). 3>1/2>-1/4>-1/6

so 3 is greatest value.

The best price can be obtained by taking the ratio and it is given for the case of two weeks ago.

The ratio of two numbers a and b can be written as a : b = a/b.

The ratio of two quantities is the unit rate of one quantity with respect to the other.

The price of gas per gallon for both the cases are calculated as below,

Two weeks ago it is given as,

Total price ÷ Number of gallons

⇒ 31.14 ÷ 9 = $3.46

And, for last week it is given as,

Total price ÷ Number of gallons

⇒ 52.70 ÷ 15 = 3.51

Thus, the price per gallon is cheaper two weeks ago.

Hence, the best price of gas is obtained for the case of two weeks ago.

Liters of fuel in 1 hr is S/E and Liters of fuel in 60 km is 60/E

Liters of fuel in 1 hr: The Quasi JX travels E kilometers per liter of fuel (EkmL)(EkmL) at S kilometers per hour (Skmhr)(Skmhr). Therefore the Quasi JX requires 1E1E liters of fuel to travel 1 km. Since the Quasi JX travels S kilometers per hour, it requires 1E1E LkmLkm × S km/hr, or SELhrSELhr

Thus, Liters of fuel in 1 hr is S/E.

Liters of fuel in 60 km: The Quasi JX travels E kilometers per liter of fuel (EkmL). Therefore the Quasi JX requires 1E1E liters of fuel to travel 1 km. Given this, the Quasi JX uses 1/E L/km × 60 km, or 60/E L of fuel to travel 60 km.

Thus, Liters of fuel in 60 km is 60/E.

The expression that represents the number of liters of fuel used in a 60 km drive under ideal driving conditions at a constant speed S is written as 60/E

Here we have given that RO1, Liters of fuel in 1 hour

Here we also know that the Quasi JX travels E kilometers per liter of fuel (E km/L) at S kilometers per hour (S km/hr)

Now, we have to know that the Quasi JX requires 1/E liters of fuel to travel 1 km.

Here the JX travels S kilometers per hour, and here it requires

=> (1/E x L/km) × (S km/hr)

Then it can be written as when we apply the value of Ro1 is 60, then we get

The coordinates of the focus of the parabola is calculated as; (0, 2).

We are told that the shape of a satellite dish can be described as parabolic. This is due to the fact that radio waves are reflected from the surface of the dish and received into the focus.

The path of the object shown in a plane curve generated by a moving point is called a parabola.

The general equation of a parabola is;

x² = 4ay

Where a is the focus of the parabola.

The given equation of the parabola is;

x² = 8y

The coordinate of the focus of the parabola is of the form; (0, a).

Comparing both equations, we have that the focus of the parabola is;

4a = 8

a = 8/4

a = 2

Hence, we conclude that the coordinate of the focus of the parabola is (0, 2).

The pounds of expensive jelly beans that Mike should use, given the amount he wants to sell the mixture, is 30 pounds.

The total weight of the mixture is x + 10 pounds because Mike adding 10 pounds of the cheaper jelly beans while the cost of the expensive jelly beans would be:

= 5 x number of pounds

= 5x

The total cost of the cheaper jelly beans is :

= 10 pounds x 2

= $ 20

The total revenue from the mixture is therefore:

= 4.25x + 42.5

The total cost is :

= 5x + 20

Equating these would find the pounds of expensive jelly beans needed :

Answer:

To reflect, place points at

2, -5

5, -5

Step-by-step explanation:

Part A: The vertex, domain, and range of the function are respectively; (5, 0), ( - ∞ , ∞ ),  [0, ∞ ]\

Part B: The function f(x) = |x| is vertically shifted by 3 units to get the function h(x) = |x| + 3. The y-coordinate of the vertex is shifted by 3 units.

Part A: The given function is g(x) = | x - 5 |.

The x-coordinate of the vertex will be: x - 5 = 0

x = 5

Therefore, the y-coordinate of the vertex will be:

y = g(x) = |x - 5|

y = g(5) = |5 - 5|

y = 0

So, the absolute value vertex is (5, 0).

Now, all real numbers fall under the expression's domain, with the exception of cases where it is undefined. In this instance, the phrase is defined even if there is no real number. Thus;

Interval Notation: ( - ∞ , ∞ )

Set builder Notation: { x | x ∈ R }

The set of all legitimate y values is the range.

Interval Notation: [0, ∞ ]

Set builder Notation: { y | y ≥ 0}

Part B: h(x) = |x| + 3 is the transformed version of the parent function f(x) = |x|.

For the parent function f(x) = |x|, the vertex is ( 0, 0).

The range of an absolute function in the form c( | ax + b | ) + k is f(x) ≥ k.

Therefore, the range of the function f(x) = |x| is f(x) ≥ 0 and in interval notation is [ 0, ∞ ).

For the transformed function h(x) = |x| + 3.

The vertex of the function is ( 0, 3 ).

The range of function is h(x) ≥ 3 and in interval notation is [3, ∞ ).

Hence, the y coordinate of the vertex is transformed by 3.
