Answer:

Solution,

BC = 40

AC = 41

Now,

$cos \: theta \: = \frac{adjacent}{hypotenuse}$

$cos \: c \: = \frac{bc}{ac}$

Plugging the values

$cos \: c \: = \frac{40}{41}$

Hope this helps..

Good luck on your assignment..

The sign of the product of –35 and –625 is

Anarel [89]

Step-by-step explanation:

The mathematical sign for the operation is subtraction.

To Solve This You Will Need To;

1] The sign of the product of -35 and -625 is;

It's going to be;

-35--625

The negative sign will turn into addition sign before you can operate it. So it's going to be;

-35+625=590(positive)

It's just like subtracting 35 from 625.

2] The sign of the product of 263 and 0 is;

263-0

With this no quantity is going to be subtracted so the 263 will remain the same. 

So 263-0=263(positive)

3] The sign of the product of -21 and 451 is;

-21-451

With this you won't subtract but rather you'll add and when you add the answer is going to be -472

-472(negative)

4] The sign of the product of -350 and 89 is;

-350-89

With this you will add it but you won't subtract the negatives so it's going to be;

-350-89=-439(negative)

Hope I am Correct I didn't really understand your question well. But Good Luck:)

Find the area of the shaded sector.

Vladimir [108]

Given that,

Radius of the circle, r = 8.91 cm

Angle, $\theta=81^{\circ}$

To find,

The area of minor sector.

Solution,

The formula for the area of minor sector is given by the formula as follows :

$A=\dfrac{\theta}{360}\times \pi r^2\\\\A=\dfrac{81}{360}\times \pi \times (8.91)^2\\\\A=56.11\ \text{cm}^2$

So, the area of the shaded sector is $56.11\ \text{cm}^2$ .

Can someone pls help me :-(

spayn [35]

Answer:

One: x = 3/32

Two: y = 3/10

Step-by-step explanation:

One

y = k*x

1/4 = k* 1/8 Multiply both sides by 8

8(1/4) = 8*k*(1/8)

8/4 = k

k = 2

=======================

3/16 = 2*x Divide by 2

3/32 = x

Two

y = 2/5

x = 1/3

2/5 = k * 1/3 Multiply both sides by 5

2 = 5*k * 1/3

2 = 5/3 * k Multiply both sides by 3

6 = 5 * k Divide both sides by 5

6/5 = k

y = 6/5 * x

x = 1/4

y = 6/5 * 1/4

y = 6/20 = 3/10
