Answer:

Tags not given out=(k/5)-40

Step-by-step explanation:

k is tag

Tags k given to student are half = k/2

Tags given to parents are= 100

Total tags given to students and parents are=(k/2)+100

So remaining tags are=k-(k/2+100)

                                    =(k-200)/2

tags given to judges and teacher are 3/5 of remaining tags =(3/5)*((k-200)/2)

So tags not given out are =(2/5)*((k-200)/2)

                                           =(k/5)-40 Answer

One geometry question <br> Please help me with this!!!!
otez555 [7]

Answer:

∠ XAZ = 50°

Step-by-step explanation:

The measure of the circle = 360°

Given arc XYZ = 230°, then

arc XZ = 360° - 230° = 130°

The tangent- tangent angle XAZ is one half the difference of the intercepted arcs, that is

∠ XAZ = \frac{1}{2} (230 - 130)° = 0.5 × 100° = 50°

If f'(x) is (x-4)(4-2x) , what is f(x)?
butalik [34]
We can apply some rules backwards

first
f'(x)=
(x-4)(-2x+4)
-2x^2+12x-16

we know that
f'(rx^n)=rnx^{n-1}
so therefor maybe
-2x^2=rnx^{n-1}
2=n-1
n=3
rn=-2
3r=-2
r=-2/3

one is
\frac{-2}{3}x^3
second part

12x
12x=rnx^{n-1}
x^1, 1=n-1
n=2
rn=12
2r=12
r=6
6x^2 is the second bit

last part
-16
-16x^0=rnx^{n-1}
0=n-1
n=1

rn=-16
1r=-16
r=-16

-16x^1

so therfor f(x)=\frac{-2}{3}x^3+6x^2-16x

The function f(x) = x2 is translated 7 units to the left and 3 units down to form the function g(x). Which represents g(x)?
nignag [31]

Answer:

B. g(x)=(x+7)^2-3

Step-by-step explanation:

Vertex form is F(x)= a(x-h)^2+k

a is the reflection

h and k are the vertex (x,y) = (h,k)

in this case there is no shrink or stretch (a)

if it is translating left or right it is "h". In this case it is translated left so its -7.  However if you look at vertex form it is "x-h" so -7-7= +7

If it translating up or down it is "K".  In this case it is translated down so its -3.  

If it was translated up or right then its positive.  If it was translated down or left its negative.

After you figure out what h and k are then you just plug it in.  h=-7, k=-3

so the answer in vertex form is, g(x)=(x+7)^2-3
