Answer:

$D=\{-2,3,5\}\\\\R=\{-2,13,19\}$

$D=\{-6,19,29\}\\\\R=\{-14,61,91\}$

$D=\{20,19,29\}\\\\R=\{64,61,91\}$

$D=\{10,19,29\}\\\\R=\{34,61,91\}$

$D=\{2,11,29\}\\\\R=\{10,37,91\}$

Step-by-step explanation:

The range of a function is the set of all possible dependent values that the function can produce. In order to find the range for the given conditions, we need to evaluate every value of the domain.

<em>When domain is:</em>

<em></em>

$D=\{-2,3,5\}$

$f(-2)=3(-2)+4=-6+4=-2\\f(3)=3(3)+4=9+4=13\\f(5)=3(5)+4=15+4=19$

<em>The range is:</em>

$R=\{-2,13,19\}$

<em>When domain is:</em>

<em></em>

<em></em> $R=\{-14,61,91\}$ <em></em>

<em></em>

<em></em> $f(-6)=3(-6)+4=-18+4=-14\\f(19)=3(19)+4=57+4=61\\f(29)=3(29)+4=87+4=91$ <em></em>

<em></em>

<em>The range is:</em>

$R=\{-14,61,91\}$

<em>When domain is:</em>

<em></em>

<em></em> $D=\{20,19,29\}$ <em></em>

<em></em>

<em></em> $f(20)=3(20)+4=60+4=64\\f(19)=3(19)+4=57+4=61\\f(29)=3(29)+4=87+4=91$ <em></em>

<em></em>

<em>The range is:</em>

<em></em>

<em></em> $R=\{64,61,91\}$ <em></em>

<em></em>

<em>When domain is:</em>

<em></em>

<em></em> $D=\{10,19,29\}$ <em></em>

<em></em>

<em></em> $f(10)=3(10)+4=30+4=34\\f(19)=3(19)+4=57+4=61\\f(29)=3(29)+4=87+4=91$ <em></em>

<em></em>

<em>The range is:</em>

<em></em>

<em></em> $R=\{34,61,91\}$ <em></em>

<em></em>

<em>When domain is:</em>

<em></em>

<em></em> $f(2)=3(2)+4=6+4=10\\f(11)=3(11)+4=33+4=37\\f(29)=3(29)+4=87+4=91$ <em></em>

Answer: The range are

(-2, 13 , 19)

(-14, 61, 91)

(64, 61, 91)

(34, 61, 91)

(10, 34, 91)

Step-by-step explanation:

f(x) = 3x + 4

Substitute the domain into the function above.

when domain are \ -2,3,5\

F(-2) = 3(-2) + 4 = -2

F(3) = 3(3) + 4 = 13

F(5) = 3(5) + 4 = 19

Range = -2, 13 , 19

When domain are \ -6,19,29\

f(x) = 3x + 4

F(-6) = 3(-6) + 4 = -14

F(19) = 3(19) + 4 = 61

F(29) = 3(29) + 4 = 91

Range = -14, 61, 91

When domain are \ 20,19,29\

f(x) = 3x + 4

F(20) = 3(20) + 4 = 64

F(19) = 3(19) + 4 = 61

F(29) = 3(29) + 4 = 91

Range = 64, 61, 91

When domain are 10,19,29\

f(x) = 3x + 4

F(10) = 3(10) + 4 = 34

F(19) = 3(19) + 4 = 61

F(29) = 3(29) + 4 = 91

Range = 34, 61, 91

When domain are \ 2,11,29

f(x) = 3x + 4

F(2) = 3(2) + 4 = 10

F(11) = 3(11) + 4 = 34

F(29) = 3(29) + 4 = 91

Range = (10, 34, 91)

Not sure what you’re trying to find but here’s the simplified version:

-4<=2t+5<11
-9<=2t<6
-9/2<=t<3

Emmanuel carves a cone-shaped hollow out of a solid clay cylinder. What is the approximate volume of the solid portion of the cy

bixtya [17]

Answer:

$3.14r^2(h-\frac{1}{3}h_1)$

Step-by-step explanation:

Let h be the cylinders height and r the radius.

-The volume of a cylinder is calculated as:

$V=\pi r^2h$

-Since the cone is within the cylinder, it has the same radius as the cylinder.

-Let $h_1$ be the height of the cone.

-The area of a cone is calculated as;

$V=\pi r^2 \frac{h}{3}\\\\=\frac{1}{3}\pi r^2h_1$

The volume of the solid section of the cylinder is calculated by subtracting the cone's volume from the cylinders:

$V=V_{cy}-V_{co}\\\\=\pi r^2h-\frac{1}{3}\pi r^2 h_1, \pi=3.14\\\\=3.14r^2(h-\frac{1}{3}h_1)$

Hence, the approximate area of the solid portion is $3.14r^2(h-\frac{1}{3}h_1)$

Two cars are traveling down the highway with the same speed. If the first car increases its speed by 1km/hr, and the other car d

Olegator [25]

Answer:

The speed of the cars is $32 \frac{km}{h}$

Step-by-step explanation:

First we must first have the clear concept that $speed=\frac{distance}{time}$ or $s=\frac{d}{t}$

Our question is the speed of the cars then the variable to clear will be s.

Let's raise the equation for each car taking into account that we have the following data:

Car 1: $s_{1}=s+1$ , $t_{1}=2$ and $d_{1}= d_{2}$

Car 1: $s_{2}=s-10$ , $t_{2}=3$ and $d_{1}= d_{2}$

The two cars travel the same distance so we will raise the distance formula for each car and then match them.

<em>Car 1</em>

$d_{1}=s_{1}*t_{1}$

$d_{1}=(s+1)*2$

$d_{1}=2s+2$

<em>Car 2</em>

$d_{2}=s_{2}*t_{2}$

$d_{2}=(s-10)*3$

$d_{2}=3s.30$

$d_{1}=d_{2}$

$2s+2=3s-30$

$2+30=3s-2s$

$32=s$

The speed of the cars is 32 km/hr
