svetoff [14.1K]

we know that

in the right triangle of the figure

Applying the Pythagorean Theorem

13^{2} =b^{2} +7^{2} \\ b^{2} =13^{2}-7^{2}\\ b^{2}=120\\ b=\sqrt{120} \ cm

therefore

the answer is the option

C) b=\sqrt{120} \ centimeters

Integrate t sec^2 (2t) dt
Neporo4naja [7]
F = t ⇨ df = dt 
dg = sec² 2t dt ⇨ g = (1/2) tan 2t 
⇔ 
integral of t sec² 2t dt = (1/2) t tan 2t - (1/2) integral of tan 2t dt 
u = 2t ⇨ du = 2 dt 

As integral of tan u = - ln (cos (u)), you get : 

integral of t sec² 2t dt = (1/4) ln (cos (u)) + (1/2) t tan 2t + constant 
integral of t sec² 2t dt = (1/2) t tan 2t + (1/4) ln (cos (2t)) + constant 
integral of t sec² 2t dt = (1/4) (2t tan 2t + ln (cos (2t))) + constant ⇦ answer

anyanavicka [17]
400 yards x 5= 2,000 yards keisha walked. 1 mile equals 1,760 yards. Now to find the 2 miles in yards multiply 1760 x 2= 3,520. So 2 miles equal 3,520 yards. Now subtract 3,520 - 2,000
