T=0=>initial
s (0)=4.5=9/2
=>s(t)=-16t^2+64+9/2
use s(-b/2a) to find height
it will take -b/2a seconds to reach that height
n I tell a,b coefficients of some

Answer:

5.8496 min

Step-by-step explanation:

$\displaystyle t=\frac{10}{\ln{2}}\int_{220}^{280}{\frac{1}{T-100}}\,dT=\frac{10(\ln{(280-100)}-\ln{(220-100)})}{\ln{2}}=\frac{10\ln{(3/2)}}{\ln{2}}\\\\\boxed{t\approx5.8496\quad\text{min}}$

Can someone please help me solve this, thank you so much if u help!

malfutka [58]

Answer:

68°

Step-by-step explanation:

The triangle containing the 79° angle is isosceles. That means the other base angle is also 79°. The central angle is ...

V = 180° -2(79°) = 22°

__

Angle X is the other acute angle in right triangle VWX, so has measure ...

X = 90° -22° = 68°

_____

<em>Additional comment</em>

A tangent makes a right angle with the radius to the point of tangency. W is the point of tangency, so angle VWX is a right angle.
