Answer:

(8, 15]

Step-by-step explanation:

If ∠A is bigger than 90 then that means 12x-6 > 90

12x > 96

x > 8

and we know that the angle must be between 0 and 180. so 12x < 186

x <= 15

the lenght of the floor is 32 m longer than its width and there is greater than 200 square meters. you will cover the floor comp

MrRa [10]

Let’s assume the width of the floor is x and the area is a

To figure out the dimensions we need to figure out the value of the variable (x)

This means that the length is xm+32m (the m is for metres) and that the area is a>200m2

Because it says what is the possible dimensions let make the area 201m2

The formula for the area of a rectangle is length times width so the equation we use to figure out the value of x

201=x+x+32

So let’s collect like terms and solve from there
201=2x+32
201-32=2x+32-32
169=2x
169/2=2x/2
84.5=x

Now that we know the value of x is 84.5 we can figure out the length is 116.5m and the width is 84.5m

Therefore the dimensions of the floor is 116.5m by 84.5m

Please help with the attached! Thanks!!

Rate of change of [1,3] is $\frac{15.882-11.38}{3-1} = \frac{4.502}{2} =22.51$
Rate of change of [-4, -2] is $\frac{.0971-.0018}{-3--4} = \frac{.0953}{1}=.0953$
The difference between them is 22.51-.0953=22.4147

Hope that helps

B) On one rectangular coordinate system, show approximate radian values for one circle, as

sleet_krkn [62]

Answer:

(See explanation below for further details)

Step-by-step explanation:

Any point in rectangular form can be described in terms of radius and angle of the circle. That is:

$P = (r\cdot \cos \theta, r\cdot \sin \theta)$

Since circunference is divided into 8 equal parts, the point can be modelled as:

$P = (r\cdot \cos \frac{2\pi\cdot n}{8}, r \cdot \sin \frac{2\pi\cdot n}{8} )$

The approximate radian and degree values for one circle are:

Radians

$0 (0), \frac{\pi}{4} (0.785), \frac{\pi}{2} (1.571), \frac{3\pi}{4} (2.355), \pi (3.142), \frac{5\pi}{4} (3.925), \frac{3\pi}{2} (4.71), \frac{7\pi}{4} (5.495), 2\pi (6.280)$

Degrees

$0^{\circ}, 45^{\circ}, 90^{\circ}, 135^{\circ}, 180^{\circ}, 225^{\circ}, 270^{\circ}, 315^{\circ}, 360^{\circ}$
