Answer:

Step-by-step explanation:

by pythagoras theorem

(hyp)^2=(leg1)^2+(leg2)^2

the hypotenuse is the side opposite to 90 degree (BC=13)

AC=leg 1 = 12

13^2=12^2 + leg 2^2

169=144+ leg 2^2

leg2 ^2=169-144

leg2^2= 25

leg2= root 25

leg2=5

Answer:

Step-by-step explanation:

The first thing to think about when doing a problem is to look in the angles. BAC is a right angle, but that does not help. The next thing to notice is BA looks roughly about 1/2 the size of AC. That answer makes the most sense so the answer is 5.

The mass, m grams, of a radioactive substance, present at time t days after first being observed, is given by the formula m=24e^

Reika [66]

Answer:

(i) The value of m when t = 30 is 13.2

(ii) The value of t when the mass is half of its value at t=0 is 34.7

(iii) The rate of the mass when t=50 is -0.18

Step-by-step explanation:

(i) The m value when t = 30 is:

$m = 24e^{-0.02t} = 24e^{-0.02*30} = 13.2$

Then, the value of m when t = 30 is 13.2

(ii) The value of the mass when t=0 is:

$m_{0} = 24e^{-0.02t} = 24e^{-0.02*0} = 24$

Now, the value of t is:

$ln(\frac{m_{0}/2}{24}) = -0.02t$

$t = -\frac{ln(\frac{24}{2*24})}{0.02} = 34.7$

Hence, the value of t when the mass is half of its value at t=0 is 34.7

(iii) Finally, the rate at which the mass is decreasing when t=50 is:

$\frac{dm}{dt} = \frac{d}{dt}(24e^{-0.02t}) = 24(e^{-0.02t})*(-0.02) = -0.48* (e^{-0.02*50}) = -0.18$

Therefore, the rate of the mass when t=50 is -0.18.

I hope it helps you!

At 10a.m the temperature was 71 degreesF. At 3 P.M the temperature was 86degrees F. Find the value of the slopes and explain wha

madreJ [45]

Values of slope = (86-71) / (3pm - 10 am) = 15 / 5 = 3

This value of the slope gives the average rise in temperature per hour.
