Answer:
Find x;
tg 45º= x/7
x=7*tg45º
x=7*1=7
Answer= x=7
Find y;
Cos 45º=7/y
y=7/ Cos45º
y=7/(√2/2)=14/√2=14√2/2=7√2
Answer= 7√2≈9.9.

Answer:
8.4$
Step-by-step explanation:
In other words, a 30% discount for a item with original price of $28 is equal to $8.4.
Answer:
Never
Step-by-step explanation:
Using the formula to find the sum of the interior angles, (n-2) * 180, we can work backwards.
300/180 +2 = 11/3 or 3.666. Polygons cannot have decimal sides therefore your answer is never.
Brainly says you need the following points
- The pattern is min-zero-max-zero-min, which is the pattern for a cosine function of the form y = acos(x) + k, but is reflected over the x-axis (so a < 0).
- The amplitude is |a|, so a = –1 and |a| = 1.
- The midline is exactly between the max and the min, y = (6 + 8)/2 = 7, so k = 7.
- The equation is y = –cos(x) + 7.
