= (4x^3y^4)/(-8xy^2)
simplify exponents by subtracting the denominator exponent from numerator exponent [x^(3-1)]
= (4x^3y^4)/(-8xy^2)
simplify -4/8 by 4 into numerator and denominator
= (-1x^2y^2)/2
= (-x^2y^2)/2
ANSWER: (-x^2y^2)/2
Hope this helps! :)
Answer:
8.2secs
Step-by-step explanation:
Given the expression for calculating the height as;
h = -16x^2+127x+80
Given h = 40
Substitute
40 = -16x^2+127x+80
-16x^2+127x+80 - 40 = 0
-16x^2+127x+40 = 0
16x^2-127x-40 = 0
Factorize
x = -(-127)±√(-127)²-4(16)(-40)/2(16)
x = 127±√16,129+2,560/32
x = 127±√18,689/32
x = 127±136.71/32
x = 127+136.71/32
x = 263.71/32
x = 8.24
Hence the required time to the nearest tenth is 8.2secs
Answer:
1) 9
2) 11
3) 13
4) 15
Step-by-step explanation:
just input the x values in the equation.
Step-by-step explanation:
Price of Jeans = $78.35
30% coupon = 30% × $78.35 = $23.51
6% sales tax = 6% × $78.35 = $4.70
1% local option tax = 1% × $78.35 = $0.78
Total cost of jeans = $78.35 - $23.51 + $4.70 + $0.78 = $60.32
I am pretty sure you would do 396x.25 on a calculator and then do that answer and x's it by 3 and that equals 297
