1. 4b - 2 : the product of 4 and a number (b) decreased by 2
2. the sum of 15 and 4 times a number......15 + 4x
3. 8 fewer boys then girls...how many boys.......b = g - 8
4. It will be less then 1 because of the negative exponent....a negative exponent will mean the number is less then 1...I dont really know how else to explain it.
5. Doug is twice Anna's age...doug is 34 years old
I dont know the 5 step plan...but I am putting what I do know
d = doug's age
a = anna's age
d = 2a
d = 34
34 = 2a
34/2 = a
17 = a....so anna is 17
check..
d = 2a
d = 2(17)
d = 34 (correct)
To perform this check, you must use the following theorem: is a lower bound for the zeroes of if, when divide by , the quotient and the remainter alternate signs.
Since the long division yields the result
You can see that the signs don't alternate (the last two terms are positive). So, -1 is not a lower bound.
In fact, the actual roots of the polynomial are -3, -2, 1, 3, so as you can see there are roots smaller than -1.
Answer:8.124. 9.42 10. TW=4.015 equation sin(35)=4.015/7. 11.WS=10.459 equation: Tan(69)=10.459/4.015
Step-by-step explanation:
use sine rule and tan rule like upwards and hope you get it right mate
I don’t think there is enough kittens being born to know, because weight is a genetic thing and it doesn’t have to be from your parents. It can be from their parents or their parents-parents and so-on.
