Answer:

No, because the curve indicates that the rate of

change is not constant.

Im 99.9 sure

Step-by-step explanation:

No, because the curve indicates that the rate of change is not constant.

The graph of a linear function is a straight line. The following is the form of a linear function. a + bx = y = f(x). One independent variable and one dependent variable make up a linear function. X and Y are the independent and dependent variables, respectively.

Given:

From the graph we can write the points as

(1, 0), (2, 25), (3, 50), (4, 100), (5, 150), (6, 200), (7, 290)

Since from the above points we can see that there is no constant rate of change followed by the points which the graph Curve.

Also, the linear function usually have the straight line graph.

Answer:

[tex]0<p\leq15.5[/tex]

Step-by-step explanation:

Amount of gasoline in the tank is 5.5 gallons

21 gallons is the capacity of the fuel tank in the car

A is the amount of gasoline in the fuel tank after purchase which will be less than or equal to 21 gallons.

So the equation will be

[tex]5.5+p\leq A\\\Rightarrow 5.5+p\leq 21\\\Rightarrow p\leq 21-5.5\\\Rightarrow p\leq 15.5[/tex]

So, the value of p is in the range of [tex](0,15.5][/tex] or [tex]0<p\leq15.5[/tex].

Step-by-step explanation:

w = .8l = 15 x .8 = 12ft

A = l x w = 15 x 12 = 180ft^2

Answer:

x = -11

Step-by-step explanation:

To find the zero of this function, factor the equation:

g(x) = [tex]x^{2} +22x+121[/tex]

g(x) = (x + 11) (x + 11)

g(x) = [tex](x+11)^{2}[/tex]

The zeros of a function are the values of x that will make g(x) equal 0. So, the zero of this function is -11, because -11 + 11 = 0. So, x = -11.

The sociologist wishes to collect data or information from these two types of people.

Answer:

Width, W = 15 inches

Step-by-step explanation:

Let L = length of the rectangle

Let W = width of the rectangle

Given the following data;

Area, A of rectangle = 375 in²

Length, L of rectangle = 25 in

*To find the width of the rectangle*

We know that the area of a rectangle is given by the formula;

[tex] Area = length * width [/tex]

[tex] A = L * W[/tex]

Making "W" the subject of formula;

[tex] W = \frac {A}{L} [/tex]

Substituting into the equation, we have;

[tex] W = \frac {375}{25} [/tex]

W = 15 in

Therefore, the width of the rectangle is 15 inches.

We know, opposite sides are parallelogram is parallel, therefore slopes are equal.

Slope of line one :

[tex]m=\dfrac{-7-(-6)}{3-1}\\\\m =\dfrac{-1}{2}\\\\m= -0.5[/tex]

So, equation of other line passing through (-4,5) and have slope of -0.5 is :

y-5 = -0.5( x-(-4))

y-5 = -0.5x - 2

y  + 1/2x = 3

2y + x = 6

Therefore, equation of line containing the (-4, 5) is 2y + x = 6.

Hence, this is the required solution.

Answer:

[tex]V=5.23\times 10^8\ m^3[/tex]

Step-by-step explanation:

A large water reservoir can be well modeled with a hemisphere whose radius is 630 meters.

The volume of a hemisphere is given by :

[tex]V=\dfrac{2}{3}\pi r^3[/tex]

Substitute r = 630 m in the above formula

[tex]V=\dfrac{2}{3}\pi \times (630)^3\\\\=5.23\times 10^8\ m^3[/tex]

So, the water reservoir can hold [tex]5.23\times 10^8\ m^3[/tex] of water.
