Note that    3 and 4 are supplemental....so  3 + 4 = 180     (1) 

And 3 + 20° + 55°   = 180     (2)

Equating (1) and (2) we have

3 + 4 =    3 + 20° + 55°          subtract  3 from both sides

So....

4 =  20°+ 55°

a₁ =  (1/2)(4/3)^(1 - 1)   = (1/2) (4/3)^0 = (1/2)(1)  = 1/2

a_n = a_n-1 (4/3)

Welcome !!!

Since 3rd and 4th are parallel.....Note that   traveling southwest on King and turning onto 3rd  is the same angle as traveling southwest on King and turning onto 4th

Since this angle is supplemental to 75°. it must = 180 - 75 =  105”

180-75=105 degrees, answer? This is because of opposite angles.

Thanks as always CPhill!

2. The relative minimum of a function is the lowest part of a graph in its "neighborhood"

In this function.....the lowest part of the graph  is the least y value.....this is  at y = -5

So....-5 is the relative minimum....[ also the absolte minimum ]

3.  Here's an easy test for eveness/oddness

Test for even.....sub -x for x.......if this equals the original function....it is even

So  (-x)^5 + 2(-x)     =  -x^5  - 2x 

This does not equal  x^5 + 2x    

Not the same....so....not even

Test for odd....if f(-x) = -f(x)

(-x)^5 + 2(-x)   =   - [ x^5 + 2(x) ]      ???

-x^5 - 2x  =  -x^5 - 2x

The same...so....odd

Blank 2   Δ BCA   is similar to  ΔBDC

Blank 4   Cross-product equality of proportions

Blank 9    Cross-product equality of   proportions

I don't unfortunately...

So 95%-92%= 3%, so therefore it is insignificant because 3% is on plot in the middle.

So you subtract 95%-93% = 3%, therefore it is insignificant because 3% is on plot in the middle.

Melody is right. This is called the binomial theorem, and it's pretty helpful to find coefficients and constants in these types of expressions.

Starting from the first term, we have \(\binom{7}{0}(3c)^7(4d)^0+\binom{7}{1}(3c)^6(4d)^1+\binom{7}{2}(3c)^5(4d)^2+...+\binom{7}{7}(3c)^0(4d)^7\)

Thus, the fourth term should be \(\binom{7}{3}(3c)^4(4d)^3\) .

Fixed.

good afternoon/morning 

I know :P

For question 1, (-6,-4) is the function is negative, it’s the only answer choice that lands on the image in the graph that is below the x-axis

hola

just kidding :D

My sister wears Nike 

For problem number 2, do you know what relative minimum and relative maximum are?

cause only me wears Nike 

yeah 

Ohhh so now it’s afternoon? Hmm interesting 😂 heh

How dare you! 😂😂😂 LOL

ya LOL

Assuming genders now? Hehe, lol jk, morning to you too
