Answer:

\boxed{\sf sin\ C =\frac{40}{41}}

Step-by-step explanation:

We need to find out the value of sinC using the given triangle . Here we can see that the sides of the triangle are 40 , 41 and 9 .

We know that the ratio of sine is perpendicular to hypontenuse .

\sf\longrightarrow sin\theta =\dfrac{ perpendicular}{hypontenuse}

Here we can see that the side opposite to angle C is 40 , therefore the perpendicular of the triangle is 40. And the side opposite to 90° angle is 41 . So it's the hypontenuse . On using the ratio of sine ,

\sf\longrightarrow sinC =\dfrac{ p}{h}\\\\\sf\longrightarrow sin\ C =\dfrac{AB}{AC}

Substitute the respective values ,

\sf\longrightarrow \boxed{\blue{\sf sin\ C =\dfrac{40}{41}}}

<u>Hence the required answer is 40/41.</u>

Suppose that a phone that originally sold for $800 loses 3/5 of its value each year after it is released.
liubo4ka [24]

Answer:

It will be worth $128.

Step-by-step explanation:

After 1 year, 3/5 of 800 is 480 which leaves the value at $320, and then after 2 years, 3/5 of 320 is 192. 320-192 leaves the value at $128.

Translate the shape A three squares right and one square down.
Alexus [3.1K]

Answer:

see explanation

Step-by-step explanation:

a shift of 3 squares right means add 3 to the x- coordinate

a shift of 1 square down means subtract 1 from the y- coordinate

translation rule is (x, y ) → (x + 3, y - 1 ) , then

(1, 1 ) → (1 + 3, 1 - 1 ) → (4, 0 )

(1, 4 ) → (1 + 3, 4 - 1 ) → (4, 3 )

(3, 1 ) → (3 + 3, 1 - 1 ) → (6, 0 )
