Answer:
80x+65 2.465 3.865
Step-by-step explanation:
x being the number of years so in ten years he will have 80x10=800+65=865
80x5=400+65=465 so 5 is the number of years it would take
and i do not understand number 1 but i put a formula just in case that was it
Answer: 25 in
Step-by-step explanation:
<u>Due to the use of the term "hypotenuse" I will assume the triangle is a right triangle.</u>
<u></u>
According to pythagorean theorem, 7²+24²=(hypotenuse)²
49+24²= (hypotenuse)²
49+576= (hypotenuse)²
625 = (hypotenuse)²
25 = hypotenuse
Hope it helps <3 :D
Answer: D
Step-by-step explanation:
Step-by-step explanation:
sin(2x) = 2sin(x)cos(x)
2sin(x)cos(x) - cos(x) = 0
so one solution is cos(x) = 0.
=> x = pi/2 and 3pi/2 (90° and 270°)
for cos(x) <> 0 we have then
2sin(x) - 1 = 0
2sin(x) = 1
sin(x) = 1/2
=> x = pi/6 and 5pi/6 (30° and 150°)
