Answer:

The answer is the option B

\sqrt{105}

Step-by-step explanation:

we have

\sqrt{105}

we know that

105=3*5*7

so

substitute

\sqrt{105}=\sqrt{3*5*7} -------> it can not be simplified

therefore

the answer is

\sqrt{105} ----> the expression can not be simplified

Cynthia has a photo frame that has a circumference of 56.52cm. What is the radius of the photo frame
Pavlova-9 [17]

Answer: 9cm

Step-by-step explanation:

The circumference of a circle is given as: = 2πr

where,

π = 3.142

r = radius = unknown

Since circumference = 56.52cm, we'll slot it into the formula which will be:

Circumference = 2πr

2πr = 56.52

2 × 3.142 × r = 56.52

6.284r = 56.52

r = 56.52 / 6.284

r = 8.99

r = 9cm approximately

Cos(-170°) = _____<br><br> -cos10°<br> cos10°<br> cos(-10°)
Lera25 [3.4K]

Answer:

<h3>-cos10°</h3>

Step-by-step explanation:

cos is positive at first and fourth quadrant

so, cos (-x) = cos (x)

also, cos(180-x) = -cos x

        cos (180+x) = -cos x

cos (-170°) = cos (170°)

cos(170°) = cos (180° - 10°)

              =  - cos 10°
