A new toy hits the local store. Sales (in hundreds) increase at a steady rate for several months, then decrease at about the sam

Montano1993 [528]

Answer:

Option A.

Step-by-step explanation:

It is given that, sales (in hundreds) for several months can be modeled by the function:

$S(m)=-0.625|m-8|+5$

We need to find the month in which 400 toys were sold.

Substitute S(m)=4 in the given function.

$4=-0.625|m-8|+5$

$4-5=-0.625|m-8|$

$-1=-0.625|m-8|$

$\dfrac{-1}{-0.625}=|m-8|$

$1.6=|m-8|$

Now,

$\pm 1.6=m-8$

$1.6=m-8$ or $-1.6=m-8$

$1.6+8=m$ or $-1.6+8=m$

$9.6=m$ or $6.4=m$

Approx the value to the next whole number.

$m\approx 10$ or $m\approx 7$

It means, 400 toys were sold on 7th and 10th month.

Therefore, the correct option is A.

Determine the number of possible triangles, ABC, that can be formed given A = 150°, a = 7, and b = 4.

When you have the length of two sides and the angle between them, the triangle is totally determined. This is, there is only one segment that can complete the triangle: its length and position is totally fixed.

An observer stands 25 feet from the base of a flagpole and watches a flag being lowered at a rate of 5 ft/sec. Determine the rat

Sedaia [141]

Answer:

0.1 rad/s

Step-by-step explanation:

Since the distance from or to the flagpole is not given, I will assume. And my assumption is 50 ft

Now, the elevation angle A = 45 degrees, converting to radians, we have π/4 radians

Remember that the tan of an angle is OPP/HYP, and so

tan A = h/25, on differentiating, we have

d tan A/dA = sec^2 A = (1/25) dh/dA

Next, we have

25 sec^2 A * dA/dt= dh/dt = 5

Making dA/dt the subject of formula, we have

dA/dt = (1/5) cos^2 A

but cos^2 A from trigonometry = 1/2, this means that

dA/dt = .1 radians/second

If you want to convert to degrees, your have

.1 Rad/s( 180 deg/rad) = 18 degrees/second
