a = p + 29
remove 1/3 of the apples, leaving 2/3
2/3 a = p+ 5 Sub in the red equation for a
2/3 (p+29) = p+5
p = 43 then a = 72
a.) 18.45 trillion is 18 450 000 000 000.00 = ( move decimal 13 places) = 1.845 x 1013
b.) 40 000 = 4.0 x 104
c.) What do you think?.......
Misssing graph or table .....
2x + 5 = 11 subtract 5 from both sides to get
2x = 6 now divide both sides by 2 to get
x = 3
I think it means divides evenly (?)
Just sub in 0 to see
39245930/8 = 4905741.25 the .25 tells us that 6 more is needed to divide evenly
39245936/8 = 4905742 Tht will be the only value......adding 8 more would change the digit in the tens place
find the zeroes of -6x^2 +25x-4 ...... this is a dome shaped parabola.... the area between the zeroes (including the zeroes) is greater than or equal to zeroe and is the domain (since you are not allowed to have a negative sqrt)
x^2 - 16 needs to be > = 0 first of all ( no sqrt of a negative)
THEN sqrt(x^2-16) also needs to be >= 0
x^2 >= 16
x >= 4 <= -4 so far -4 >=x>=4
These values will result in a positive sqrt .....adding +3 will still be a positive sqrt
What does the ' | ' symbol mean?
6t^2 -47t+30 = 0
Use quadratic Formula to find the roots a = 6 b = -47 c = 30
\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)
Final amount = 10 000 (1+.10)3
