You can proceed like this,

650 kb for a pic
and 2200kb for song ( 650 + 1550)

total= 18150 kb  and 16 files

so, 650 kb each in both pic and song = 16 * 650= 10400

remaining = 18150-10400 = 7750 , which is contributed by  additional 1550 of songs that is  
7750/1550 = 5

so, a total of 5 songs and 11 pictures were  sold..

hope it helped

Find the zeros of the polynomial function and state the multiplicity of each.
zheka24 [161]
\bf f(x) = 4(x + 7)^2(x - 7)^3\implies 0 = 4(x + 7)^2(x - 7)^3
\\\\\\
0=(x+7)^2(x-7)^3\implies 
\begin{cases}
0=(x+7)^7\\
\qquad 0=(x+7)(x+7)\\
\qquad -7=x\\
\qquad -7=x\\
----------\\
0=(x-7)^3\\
\qquad 0=(x-7)(x-7)(x-7)\\
\qquad 7=x\\
\qquad 7=x\\
\qquad 7=x
\end{cases}

the -7 is found there twice, so it has a multiplicity of 2
the +7 is there thrice, so it has multiplicity of 3

Can someone please help me do this
Viefleur [7K]

Answer:

Step-by-step explanation:

CD is Pole

∠CAD = 4°  {Alternate interior angles}

ΔCAD,

\dfrac{opposite \ side}{adjacent \ side}= tan 4\\\\ \dfrac{90}{AD}=tan \ 4\\\\ \dfrac{90}{AD} = 0.069\\\\90 = 0.069*AD\\\\ \dfrac{90}{0.069}=AD\\\\AD = 1304 \ ft

In ΔCDB,

∠B = 5° {Alternate interior angles}

Tan \ 5 = \dfrac{90}{BD}\\\\0.09* BD = 90\\\\BD =   \dfrac{90}{0.09}\\\\BD = 1000 \ ft

Need to keep cell bill under 60.,monthly charge is 30. And texts are 0.05 each. Write an inequality to represent the # of texts
nignag [31]

Answer:

30 + 0.05x < 60

The number of texts she can have is less than 600.

Step-by-step explanation:

Total monthly charge

30 + 0.05 for each text.

So, for x tests, the charge is:

C(x) = 30 + 0.05x

Write an inequality to represent the # of texts she can have?

It has to be under 60, so:

C(x) < 60

30 + 0.05x < 60

The solution is:

0.05x < 30

x < \frac{30}{0.05}

x < 600

The number of texts she can have is less than 600.
