Answer:
Replace the variable t with −
2
in the expression. 3.5
Step-by-step explanation:
-9.8t+20t+8t=-2,0,3.5
-9.8t+20t+8t=-2 18.2t=-2
=03.5 18.2=t-2
Uhh, these give me a headache, I think number 2 is array..
Answer:
ln 2.
Step-by-step explanation:
One of the rules of logarithms is
ln a - ln b = ln a/b.
So ln 16 - ln 8 = ln 16/8
= ln 2.
Answer:
This equation is in standard form: ax 1+bx+c=0. Substitute 9 for a, 16 for b, and −112 for c in the quadratic formula 2a−b±b2−4ac.x= 2×9−16± 16^2−4×9(−112)Square 16.x=2×9−16±256−4×9(−112) Multiply −4 times 9.x=2×9−16± 256−36(−112) Multiply −36 times −112.x=2×9−16±256+4032 Add 256 to 4032.x=2×9−16±4288 Take the square root of 4288.x=2×9−16±8+67 Multiply 2 times 9x=18−16±8=67
Step-by-step explanation:
hope this help if not let me know
Answer:
false
Step-by-step explanation:
A linear equation has x to the first power
or of the form x plus a constant
This has x to the fifth power so it is not linear
