Answer:

  -1209

Step-by-step explanation:

Your sequence has first term a1 = -29 and common difference d = -20. Using these in the formula for the n-th term, we can find the 60 term.

  an = a1 +d(n -1)

  an = -29 -20(d -1)

  a60 = -29 -20(60 -1) = -1209

Answer:

D. log(9)

Step-by-step explanation:

log(9x^{5})+5log(\frac{1}{x})

Remember: A log (x) = log(x^{A})

log(9x^{5})+log((\frac{1}{x})^{5})

Remember: log_{a} (x)+log_{a}(y)=log_{a}(xy)

log(9(\frac{1}{x})^{5}x^{5})

Simplify...

log(9)

Hope this helps! If you need steps for simplifying, just ask! :]

I want help its urgent!!! <br><br>(iv), (v), (vi) Questions​
Artist 52 [7]

Solution:

iv) Given equation: x^{2} - y^{2} - 4x - 2y + 3

Since we are given two variables, we need to split the original expression into two quadratic expressions as

x^{2} - 4x + 4 - y^{2} - 2y - 1

Factoring x first:

x^{2} - 4x + 4 = x^{2} - 2x - 2x + 4

= x (x - 2) - 2 (x-2)

= (x-2)(x-2)

= (x-2)^{2}

Factoring y now:

-y^{2} - 2y - 1 = -1(y^{2} + 2y + 1)

= -1(y^{2} + y + y + 1)

= -1[ y(y+1) + 1(y+1)]

= -1 [(y+1)(y+1)]

= (y+1)(-y-1)

Therefore, the original expression becomes

(x-2)^{2}+(y+1)(-y-1)\\or \\(x-2)(x-2) + (y+1)(-y-1)

In 2000 pizza costs 7.50 and in 2015 it costs 9.00 what is the percentage of change in the cost of the pizza
padilas [110]
Percentage change = difference/original x 100

(9.00-7.50)/7.50 x 100 = 2.50/7.50 x 100
= 1/3 x 100
= 33.3% increase
