Remember that x =r cos theta and y = r sin theta. Thus,
x + y = r (cos theta + sin theta) = 4, or
r (cos theta + sin theta) = 4, or
4
r = -------------------------------
cos theta + sin theta
Answer: $2520
Step-by-step explanation:
The simple Interest earned on a deposit of P that has a rate of r% and a period of t years can be calculated by using the formula:
(P × R × T)/100
where P is principal
R is rate
T is time
P=$10,500
R=6%
T=4 years
Therefore:
Interest= (10500 × 6 × 4)/100
= 252000/100
= 2520
Sally will earn $2520 as interest after 4 years.
Answer:
The statement contrapositive to the given statement is,
If point B is not the midpoint, then point B does not bisect the line segment AC into two congruent segments.
Step-by-step explanation:
The given statement is,
If point B bisects line segment AC into two congruent segments, then point B is the midpoint.
The statement contrapositive to the given statement is,
If point B is not the midpoint, then point B does not bisect the line segment AC into two congruent segments.
Note :-
If a statement is such that,
A ⇒ B
then A ⊆ B
and it's contrapositive statement is,
⇒ 
implying that,
⊆
Answer:
A, C, D
Step-by-step explanation:
In a proportional relationship, y = kx, k is the constant of proportionality.
A)
4y = x
y = 1/4 x
k = 1/4 Yes
B)
y = 4x
k = 4 No
C)
32y = 8x
y = 8/32 x
y = 1/4 x
k = 1/4 Yes
D)
y = 0.25x
k = 0.25 = 1/4 Yes
E)
1/4 y = 2x
y = 4 * 2x
y = 8x
k = 8 No
Answer: A, C, D
