If there is 23 classrooms and each has 10 then you would have to times 23 by 10 - 23x10=230
Answer: the rate at which its altitude is changing is -47 ft/s
Step-by-step explanation:
Given that;
ds/dt = 45 mph = 45 × 5280/3600 = 66 ft/sec
no we have to determine dx/dt
so
cos∅ = dx/dt / ds/dt
cos45° = dx/dt / 66
dx/dt = 0.7071 × 66
dx/dt = 46.6686 ≈ 47 ft/s ( as altitude is decreasing, its negative - )
so the rate at which its altitude is changing is -47 ft/s
Answer:

Answer: Y= 3/2x-8=
Step-by-step explanation:Y=4 M= 3/2. X=-8
Y=mx+b
4 = 3/2(8)+b
4= 24/2+b
4= 12+b
-12=-12
-8=b
The product of the expression given above most likely yield a complex number since the expression as well is a complex number. A complex number is a real number, an imaginary number or a number with both real and imaginary number. Its standard form is:
a + bi
<span>( 9 + 5i)( 9 + 8i)
</span>81 + 72i + 45i -40
41 + 117i
