D since it looks pretty difficult
Answer:
so yes
Step-by-step explanation:
If you can divide two numbers without a remainder, then the first number is divisible by the second.
For example, 12 is divisible by 2.
12÷2=6
But 12 is not divisible by 5. When you divide 12 by 5, you get a remainder.
12÷5=2 R2
F(x) = 4.x2 +1 is the answer.
A] <span>A remote-control airplane descends at a rate of 2 feet per second. After 3 seconds it is 67 feet above the ground.
the point slope equation will be given as follows:
y-y1=m(x-x1)
where:
slope,m=2 ft/sec
(x1,y1)=(3,67)
thus plugging in the values in the formula, we obtain the point slope equation as follow:
y-67=2(x-3)
Answer:
</span>y-67=2(x-3)
b]The height of the plane after 8 seconds will be:
x=8 sec
but:
y-67=2(x-3)
substituting x=8 we get:
y-67=2(8-3)
y-67=2(5)
y=10+67
y=77
thus the height after 8 seconds is 77 ft
Answer:
see explanation
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
Given
=
and r =
, then
a
=
, that is
= 
=
( cross- multiply )
32a = 2048 ( divide both sides by 32 )
a = 64 ← first term
Thus the explicit formula is
= 64
