Find the range f(x)=2x-3 for the domain {-1, 0, 4, 7}

Yakvenalex [24]

Answer:

The set of output values are (1,3,11,17) as Range

Step-by-step explanation:

Given function is f(x)=2x-3 and domain is (-1,0,4,7)

Function is given that taking set of input values from domain and give out set of output values.

For x=(-1)

f(x)=2x-3

f(-1)=2(-1)+3=(-2)+3=1

For x=0

f(x)=2x-3

f(0)=2(0)+3=3

For x=4

f(x)=2x-3

f(4)=2(4)+3=-8+3=11

For x=7

f(x)=2x-3

f(7)=2(7)+3=14+3=17

Thus,

The set of output values are (1,3,11,17) as Range

Aleka and Helene both opened savings accounts that earn 2.5% interest a year. Aleka puts $2,500 into her account. Helene put $1,

Angelina_Jolie [31]

Answer:

$h(x)=1000(1.025)^x-200x$ .

Step-by-step explanation:

We are given function f for Aleka's amount

$f(x)=2500(1.025)^x$

And function for Helene's amount

$g(x) = 1500(1.025)^x+200x$ .

Now, we need to find the difference of the functions h(x) = f(x)-g(x).

Subtracting f(x) and g(x), function, we get

$h(x) =2500(1.025)^x-(1500(1.025)^x+200x)$

Distributing minus sign over second parenthesis, we get

$h(x) =2500(1.025)^x-1500(1.025)^x-200x$

Subtracting $2500(1.025)^x-1500(1.025)^x$ , we get 1000.

Therefore, $h(x)=1000(1.025)^x-200x$ .

different animals have different fields of view. humans can generally see a 180° arc in front of them. horses can see 215° arc.

IgorLugansk [536]

Answer:

The area of the riders field of view is 987.5 square yards.

Step-by-step explanation:

The human has a 180° arc view. If the rider can see only 25 yards, the area of the riders field of view is a semi-circle (180° arc) of 25 yards of radius.

The semi-circle of 25 yards of radius has an area of:

$S=\dfrac{1}{2}\pi r^2=\dfrac{1}{2}\cdot3.16\cdot (25)^2=\dfrac{1}{2}\cdot3.16\cdot625=987.5$

The area of the riders field of view is 987.5 square yards.

What is the volume of the cylinder below? A cylinder with a height of 12 millimeters and diameter of 18 millimeters. 108 pi mm3

Artemon [7]

Answer:

V =972 pi mm ^3

Step-by-step explanation:

The diameter is 18 so the radius is 1/2 of the diameter

18/2 = 9

r=9

The volume of a cylinder is

V = pi r^2 h

V = pi (9)^2 12

V =972 pi mm ^3
