If sin (7y) = cos (5y + 14), find y.

Mathematics
1 answer:
Reil [10]4 years ago
7 0

Answer:

Step-by-step explanation:

sin(7y)=cos(5y+14)=sin(90-(5y+14))=sin(76-5y)

7y=76-5y

12y=76

y=76/12=19/3

or

sin(7y)=cos (5y+14)=sin (90+(5y+14))=sin (5y+104)

7y=5y+104

2y=104

y=52

44 × 20 × 10 = 440 × 2. but is it true or false ?
Vinil7 [7]
If you would like to know if 44 * 20 * 10 equals to 440 * 2, you can check it like this:

44 * 20 * 10 = 440 * 20 = 8800
and
440 * 2 = 880

So, the correct result is False, because 8800 is not equal to 880.

Terrance is making a scale model of a
Tanya [424]

Answer:

6.4 inches

Step-by-step explanation:

We are going to have to use ratio's here. We know that 1 inch = 2.5 feet and we know that Terrance is making a scale model of a  car that is 16 feet long. We need to work out the length of the car in inches so,

1 inches = 2.5 feet

? inches = 16 feet

→ We are going to divide 16 by 2.5 and then multiply that answer by 1 to get our result so

16 ÷ 2.5 = 6.4

6.4 × 1 = 6.4

The final answer is 6.4 inches
