Greeley [361]3 years ago

Answer:

Step-by-step explanation:

it is hard to know exactly by eye balling the graph  I can't dissern the y intercept it might be 4.5 but it could be 4.33, but it looks for sure like the x intercept equals 6 but does it

the dots on the line are at (-2, -6) and (2, 3)  so we can find the slope m

in the y = mx + b line equation   b is the y intercept

m = Δy/Δx     =  (y1 - y2) / (x1 - x2)

                     =  (-6 - -3) /  (-2 - 2)

                     =     -3 / -4

                 m = 3/4

       y = 3x/4  +  y intercept     which i can't dissern (read directly from the

                                                  graph, but we believe y = 0   when x is six

       0 = 3(6)/4  + y intercept

       

       -18/4 = 18/4 -18/4  + y intercept

        -9/2 = y intercept

        -4.5 = y intercept

   y = 3x/4 - 9/2          i think exact number means NO FRACTIONS but that is whole number so let me gaggle it  What are exact numbers?  Gaggle indicates exact numbers are integers   example  3 ft in a yard 12 eggs in a dozen

    y = 3x/4 - 9/2               multiple both sides by 4

   4y = 3x  - 36/2

   4y = 3x - 18    <------------------  FINAL ANSWER

Which expression is equivalent to ^
mash [69]

Answer:

Step-by-step explanation:

lets break down 120 to see what it is divisible by and see if any of those numbers are perfect squares.

120/2=60

120/3=40

120/4=30

we can stop there because 4 is a perfect square and 30 can not be reduced any further to produce a perfect square.

do not forget there is only one x so it must stay in side the  radical.

your answer is 2sqrt(30x)

CODES Use the following information to solve. A bank gives each new customer a 4-digit code number which allows the new customer
MaRussiya [10]
<h3>Answer:  D) 1/24</h3>

=============================================================

Explanation:

There are 4 digits to pick from and 4 slots to fill, so there are 4! = 4*3*2*1 = 24 different codes possible.

If we want the code to start with 371, then that must mean 5 is the only thing left for that fourth slot. In short, there's only one code that starts with 371 and that code is 3715

We have one code we want (3715) out of 24 total, which is why the answer is 1/24 (choice D)

Find the length of the curve y = 3/5x^5/3 - 3/4x^1/3 + 6 for 1 &lt; = x &lt; = 8. The length of the curve is . (Type an exact an
Mashutka [201]

Answer:

\sqrt\frac{387}{20}

Step-by-step explanation:

Arc Length =\int\limits^a_b {\sqrt{1+(\frac{dy}{dx})^2 } } \, dx

y=\dfrac{3}{5}x^{\frac{5}{3}}-  \dfrac{3}{4}x^{\frac{1}{3}}+6

\frac{dy}{dx} =x^{\frac{2}{3}}-\dfrac{1}{4}x^{-\frac{2}{3}}

1+(\frac{dy}{dx})^2 }=1+(x^{\frac{2}{3}}-\dfrac{1}{4}x^{-\frac{2}{3}})^2\\=1+(x^{\frac{4}{3}}-\dfrac{1}{2}+ \dfrac{1}{16}x^{-\frac{4}{3}})

=\dfrac{1}{2}+x^{\frac{4}{3}}+ \dfrac{1}{16}x^{-\frac{4}{3}}

For the Interval 1\leq x\leq 8

Length of the Curve =\int\limits^8_1 {\sqrt{\dfrac{1}{2}+x^{\frac{4}{3}}+ \dfrac{1}{16}x^{-\frac{4}{3}} } } \, dx\\

Using T1-Calculator

=\sqrt\frac{387}{20}
