Answer:Area of part 1:

A1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

Area of part 2:

A2=length*width=(8+2)*1=10 ft2

Area of part 3:

A3=length*width=8*2=16 ft2

Total shaded area : A1+A2+A3=41 ft2

Total area of the reactangle : A=16*8=128 ft2

Total area of the nonshaded region : 128-41=87 ft2

Katarina [22]

First of all, we can just ignore A, it has no effect but to vertically stretch our cosine.

If it was only $f(x)=cosx$ , the function would be invertible as long as it's confined between $0$ and $\pi$ . Now, the argument of our cosine is not $x$ but $bx$ . It means that it won't stop at $\pi$ , but at $\frac{\pi}{b}$ .

Another way to think about it, "what should i replace x with so I get $\pi$ inside the cosine?"

EastWind [94]

Given that Sarah the cheetah ran 100 meters at a speed of 16.8 meters per second.

An olympian ran the 100-meter dash in 9.6 seconds.

Then speed of olympian = distance/ time = 100 meter/ 9.6 seconds = 100 meter/ 9.6 seconds = 10.4166666667 meter/ seconds

whis is approx 10.42 meter/seconds

Now we need to find about how much faster was Sarah the cheetah’s speed, to the nearest tenth of a meter per second.

16.8-10.42 = 6.38 = 6.4

Hence speed of Sarah the cheetah's is approx 6.4 meter per second more than the speed of olympian.

PLEASE HELP ME!!! I AM SO CONFUSE!!!

Volgvan

Multiply both sides by (3*5)
5(2n)=3(n+14)
distribute
10n=3n+42
minus 3n both sides
7n=42
divide both sides by 7
n=6
