THANK YOU !!!
I really don't know how to calculate this question.
(3 tan 45°)(4 sin 60°)-(2 cos 30°)(3 sin 30°)
Answer:
, which is equal to .
Step-by-step explanation:
An angle of corresponds to an isosceles right triangle: the length of the two legs (adjacent and opposite) would be equal. Accordingly:
.
Let denote the measure of an angle. Double-angle identity for sine:
.
By this identity:
.
( in this instance.)
Hence:
.
. Therefore, .
Answer:
the answer is A) X=m/n-p
Step-by-step explanation:
m/x=n-p
n-p=m/X
(n-p)×x=m
X=m/n-p
B(−45, 42), (−17, 42), (−17, 21), (−45, 21)
C(−105, 42), (−77, 42), (−77, 21), (−105, 21)
D(−35,−28), (−7,−28), (−7,−49), (−35,−49)
By first dilating and then translating the given coordinates of the rectangle, we obtain the final coordinates as (−35, 32), (−7, 32), (−7, 11), (−35, 11). The correct answer is A.
The process of dilation involves multiplying the x and y coordinates of each vertex of the rectangle by a certain factor. In this case the factor is 7, which gives us the following set of coordinates after dilation: (−35, 42), (−7, 42), (−7, 21), (−35, 21). After the dilation, the rectangle is then translated down 10 units, which involves subtracting 10 from each of the y-coordinates. Following the translation, the final set of coordinates of the rectangle is (−35, 32), (−7, 32), (−7, 11), (−35, 11). Therefore, the correct answer is A.

Answer:
Arithmetic Sequence:
d=4
Step-by-step explanation:
This is an arithmetic sequence since there is a common difference between each term. In this case, adding 4 o the previous term in the sequence gives the next term. In other words, aₙ=a₁+d(n-1)
