Recall that for all t,
cos²(t) + sin²(t) = 1
Now,
x = 5 cos(t) - 7 ⇒ (x + 7)/5 = cos(t)
y = 5 sin(t) + 9 ⇒ (y - 9)/5 = sin(t)
so that substituting into the identity above, we get
((x + 7)/5)² + ((y - 9)/5)² = 1
which we can rewrite as
(x + 7)²/25 + (y - 9)²/25 = 1
(x + 7)² + (y - 9)² = 25
and this is the equation of a circle centered at (-7, 9) with radius 5.
<h2>x = 3</h2>
Step-by-step explanation:
Step 1 Use 3 to open the bracket
Step 2: Collect like terms and simplify
Step 3: Divide both sides by 7
Answer:
26.88
Step-by-step explanation:
20%*22.40=4.48
22.40+4.48=26.88
Answer:
24
Step-by-step explanat
Divide both the numerator and denominator by the GCD
1032 ÷ 43
43 ÷ 43
Reduced fraction:
24
1
Therefore, 1032/43 simplified to lowest terms is 24/1.
They will need 3 cars, but one of the cars will be having 3 passengers instead of 4. :)
