Answer:

We can write the range for w as :  18 ≤ w ≤ 34

Step-by-step explanation:

The perimeter of rectangle is given as :

P = 2 ( length + width)  

or  P = 2 l + 2 w

Now, given the length of the garden is 16 feet

Also given is that the perimeter of the garden must be at least 68 feet and no more than 100 feet.

So, this can be written  as :

68 \leq P \leq 100

or,  68 \leq (2l + 2w) \leq 100

Substitute l = 16, we get:

68 \leq (2(16) + 2w) \leq 100

68 \leq (32 + 2w) \leq 100\\\implies 68 - 32\leq 2w \leq 100-32\\\implies 36\leq 2w \leq  68\\\implies 18\leq w \leq 34

So, we can write the range for w as :  18 ≤ w ≤ 34

Need help with A and C <br><br>please :)
Dennis_Churaev [7]

First step: name the sides according to geometry standards, namely, the sides are named the same lowercase letter as the opposing angle. A revised diagram is shown.

Second step: we need to know the relationships of the trigonometric functions.

cosine(A)=cos(63) = adjacent / hypotenuse = AC/AB .................(1)

sine(A)=sin(63) = opposite / hypotenuse = CB/AB .......................(2)

We're given AB=7, so

using (1)

AC/AB=cos(63)

AC=ABcos(63)=7 cos(63) = 7*0.45399 = 3.17993 = 3.180 (to three dec. figures)

Using (2)

BC/AB=sin(63)

BC=ABsin(63) = 7 sin(63) = 7*0.89101 = 6.237 (to three dec. figures).

* this is pretty difficult for me , provide details if necessary * // ANSWER ASAP //
fredd [130]

Answer:

A.

Step-by-step explanation:

1 radian = 180/π

So

Multiplying both sides by 25π/18

We'll get,

25π/18 (r) = (180/π)×(25π/18)

= (180×25)/18

= 10×25

= 250 degrees
