If period of
is one-half the period of
and
<span>
has a period of 2π, then
and
.
</span>
To find the period of sine function
we use the rule
.
<span /><span />
f is sine function where f (0)=0, then c=0; with period
, then
, because
.
To find a we consider the condition
, from where
.
If the amplitude of
is twice the amplitude of
, then
has a product factor twice smaller than
and while period of
<span> </span> is 2π and g(0)=0, we can write
.
Answer:
$6
Step-by-step explanation:
when you multiply $30 by 20% you get 6. 30-6= $24 after the 20% is taken off, but he saved $6.
You’re right, both of the pairs are similar
Answer:
it would be
The dependent variable is distance, the equation is y = 35x, and the dragonfly will travel 840 miles
Step-by-step explanation:
By the graph it can be seen that the distance a dragonfly can travel is dependent on the certain number of hours.
∴ Dependent variable : Distance (on y axis)
The equation of straight line is given by :-
, here m is the slope of the line and c is the initial value of y at x=0.
From the given graph, the slope of the given line passing from (0,0) and (2,70) will be :-
Also, the value of y = 0 at x=0.
∴ The equation of the given line :
At x=24,
∴ The dragonfly will travel 840 miles in 24 hours.
1) y = 3
2) C.) 8 * 60 - 8 * 6 ⇒ it will look like this 8(60-6) ⇒ 8(54)
3) A) 7u + 5v
4) 4x³ and x³ are like numbers
5) Simplify: 5x³ - 2x² + x + 4x³
group like numbers: 5x³ + 4x³ - 2x² + x
9x³ -2x² + x ⇒ letter C.
