The discount would be £9.79. You would take 45% amd make it a decimal, then times the decimal by 19. Once you have that answer you will subtract it from 19.

Make a table for each function rule. Then graph each equation using the points you created.
aleksandrvk [35]

Answer:

1.f(x)=2x-5

i will take the set {-2,-1,0,1,2}

f(-2)=2(-2)-5

=-4-5

=-9

f(-1)=2(-1)-5

=-2-5

=-7

f(0)=2(0)-5

=-5

f(1)=2(1)-5

=-3

f(2)=2(2)-5

=-1

so the coordinates of the function is {-9,-7,-5,-3,-1}

2.f(x)=-3x+6

i will the take the set {-2,-1,0,1,2} too

f(-2)=-3(-2)+6=6+6=12

f(-1)=-3(-1)+6=3+6=9

f(0)=-3(0)+6=6

f(1)=-3(1)+6=-3+6=3

f(2)=-3(2)+6=-6+6=0

{12,9,6,3,0}

3.f(x)=2/3.x+4

{-2,-1,0,1,2}

f(-2)=2/3(-2)+4=-4/3+4=(-4+12)/3=8/3

f(-1)=2/3(-1)+4=-2/3+4=(-2+12)/3=10/3

f(0)=2/3(0)+4=4

f(1)=2/3(1)+4=2/3+4=(2+12)/3=14/3

f(2)=2/3(2)+4=4/3+4=(4+12)/3=16/3

{8/3,10/3,4,14/3,16/3}

you're can graph those coordinates

actually you can take other coordinates...

Prove that the curve a(t) = (cost, sin 2t, cos 2t) is regular on R and that it self-intersects at (1,0,1). Check the self-inters
alexandr402 [8]

Answer:

The function a (t) is a vector function composed of the component functions a_ {1} (t) = cost, a_ {2} (t) = sin2t and a_ {3} (t) = cos2t. How a_ {1} (t), a_ {2} (t), a_ {3} (t) are infinitely derivable functions in R, so they are regular functions in R.

Now, fort = 0, you have to a (0) = (cos (0), sin2 (0), cos2 (0)) = (1, 0, 1). How the functions a_ {1} (t), a_ {2} (t), a_ {3} (t) are periodic functions with period 2 \pi, the vector function a (t) will take the same point (1, 0 , 1) at t = 2n\pi, n = 0, 1, 2, 3, ... then the vector function is auto-intercepted

the area of a rectangular wall of a barn is 117 square feet. its length is 4 feet longer than the width. find the length and wid
Yuliya22 [10]

Area is the product of length and width. If you assume the dimensions are integers, you are looking for factors of 117 that differ by 4.

117 = 1×117 = 3×39 = 9×13

These last two factors differ by 4, so we know the dimensions of the barn are ...

... 9 ft wide by 13 ft long
