tails. Makavla wins. If one is heads and one is tails, Robert wins.

Answer:

The sets of the domain and the range of T are, respectively:

[tex]Dom \{T\} =\{-3,0,3\}[/tex]

[tex]Ran\{T\} = \{-4.-3,2,3\}[/tex]

Step-by-step explanation:

The values of the relation T that belongs to the domains correspond with the values on the x-axis and associated with the given points, whereas the range corresponds with the respective values of the y-axis. Let [tex]T = \{(x,y)|(-3,3),(3,2),(0,-3),(3,-4)\}[/tex]

The sets of the domain and the range of T are, respectively:

[tex]Dom \{T\} =\{-3,0,3\}[/tex]

[tex]Ran\{T\} = \{-4.-3,2,3\}[/tex]

Area of a Rectangle

The image shows a rectangular vegetable garden with different crops.

The rectangle has a length of L=2x+9 yards and a width of W=6x-3 yards.

The area of a rectangle is:

A = WL

[tex]A=(2x+9)(6x-3)[/tex]

Operating:

[tex]A=2x(6x)-2x(3)+9(6x)-9(3)[/tex]

[tex]A=12x^2-6x+54x-27[/tex]

Simplifying:

[tex]\boxed{A=12x^2+48x-27}[/tex]

Answer:

It's a triple stack

Step-by-step explanation:

x + y = 3. => y = 3 - x

5x + y = 5x + (3 - x) = 15.

=> 4x + 3 = 15

=> 4x = 12, x = 3.

Therefore y = 3 - (3) = 0.

The solutions are x = 3 and y = 0.

Answer:

Step-by-step explanation:

x+y=3

5x+y = 15

I method:

y = 3 - x. substitute this in 2nd equation

5x + (3-x) = 15

5x + 3 - x = 15

4x = 12

x=3

y=0

II method:

subtracting 2nd equation and 1st equation we get

4x +0y = 12

x = 3

y = 0

The height of the triangular cross section of the prism will be [tex]2.5 \ cm[/tex] .

Prism is a polyhedron comprising an [tex]n-[/tex]sided polygon base, a second base which is a translated copy of the first, and [tex]n[/tex] other faces, necessarily all parallelograms, joining corresponding sides of the two bases. All cross-sections parallel to the bases are translations of the bases.

And,

Volume of prism [tex]= Base\ Area\ *\ Length[/tex]

We have,

Volume of prism [tex]=35 cm^3[/tex]

Length of prism [tex]=7cm[/tex]

Height of prism [tex]=h\ cm[/tex]

We also have,

Base of triangle [tex]=4\ cm[/tex]

One of the side of triangle [tex]=5\ cm[/tex]

As we have Triangular prism so Base area of prism will be the area of triangle.

so,

Area of triangle [tex]=\frac{1}{2}*base*Height[/tex]

                          [tex]=\frac{1}{2} * 4*h[/tex]

Area of triangle [tex]=2h[/tex]

Now,

Volume of prism [tex]= Base\ Area\ *\ Length[/tex]

                       [tex]35=2h*7[/tex]

                        [tex]h=\frac{5}{2}[/tex]

                         [tex]h=2.5 \ cm[/tex]

So, the height of prism is [tex]2.5\ cm[/tex] .

Hence, we can say that the height of the triangular cross section of the prism will be [tex]2.5 \ cm[/tex] .

Answer:

Step-by-step explanation:

V of a cone V=3.14* r^2*h/3

942=3.14*r^2*9/3

r^2=942/(3.14*3)=100

r=sqrt100=10

The radius of the cone when the volume of 942 cubic inches and a height of 9 inches should be 10.

Since there is  a volume of 942 cubic inches and a height of 9 inches

We know that

Volume of a cone V=[tex]3.14* r^2*h/3[/tex]

So,

[tex]942=3.14*r^2*9/3\\\\r^2=942/(3.14*3)=100[/tex]

r =[tex]\sqrt 100[/tex]

=10

hence, The radius of the cone when the volume of 942 cubic inches and a height of 9 inches should be 10.

Answer:

  216 mi/h

Step-by-step explanation:

The time for the trip with the wind is ...

  (1080 mi)/(225 +45 mi/h) = 4 h

The time for the trip against the wind is ...

  (1080 mi)/(225 -45 mi/h) = 6 h

The average speed for the entire round trip is ...

  (2160 mi)/(4 +6 h) = 216 mi/h

Answer:

306.94 cm

Step-by-step explanation:

The formula for volume of a cylinder is pi×r^2×h. Im assuming that you mean that the base is 6.5 cm in diameter so in this case you would plug in the values and do pi×3.25^2×9.25 and get 306.94 cm

The measurements that can be used to build a right-angled triangle are

[tex]6 in, 8 in, 10 in[/tex]

The measurements that can be used to build a right-angled triangle must form a Pythagorean triple. A Pythagorean triple is a set of three numbers [tex]\{x,y,z\}[/tex] that satisfy the Pythagorean relationship

[tex]x^2+y^2=z^2[/tex]

The measurements [tex]\{5 in, 7 in, 12 in\}[/tex] do not form a triple since

[tex]5^2+7^2=74\ne12^2[/tex]

The measurements [tex]\{8 in, 12 in, 14 in\}[/tex] do not form a triple since

[tex]8^2+12^2=208\ne14^2[/tex]

The measurements [tex]\{5 in, 9 in, 11 in\}[/tex] do not form a triple since

[tex]5^2+9^2=106\ne11^2[/tex]

The measurements [tex]\{6 in, 8 in, 10 in\}[/tex] form a triple since

[tex]6^2+8^2=100=10^2[/tex]

So, the last set of measurements [tex]6 in, 8 in, 10 in[/tex] can be used to build a right-angled triangle

Answer:

(-10,-7)

Step-by-step explanation:

the given equations: y=-3 and x=-10

we can substitute the x in the first equation as -10.

y=(2/5×-10)-3

simplify

y=(2/1*-2)-3

y=-4-3

y=-7

the y value is -7

we actually have the x value given as -10 (in the system)
