Mathematics

Answer:

y = 4cosx

Step-by-step explanation:

Since we have cosx lying between -1 and 1, we have

y =4cosx lying between 4(-1) and 4(1)

i.e. maximum value is 4.

II option is incorrect because cos4x has maximum value only as 1.

III option is also incorrect because cos(x)+4 has maximum as 1+4=5

IV option is also incorrect because cos(x+4) has maximum as 1

As a result we have out of 4 options given only I option satisfies the condition that the function has a maximum value of 4.

Tju [1.3M]
Ok so do 100 divided by 77 to get about 1.3% per fruit. then do 1.3 times 53 to get the current percent of oranges which is about 69% then do 84% minus 69% to get the difference then divide by 1.3 to get about 11.5 oranges so you round to 12 oranges. So 12+53 to get 65 total oranges to equal 84% of the 77 fruit in the box.

Answer: 8) 42°, 65°, 115°     9) 1.5, 2

Step-by-step explanation:

8) Right off the bat I know that the measure adjacent to 157° is

   23°. With both numbers inside the triangle combined, we get

   65° meaning the last number is 115 because that'll add up to 180°

9) Considering the smaller triangle has half the length of the bigger triangle

   The length of the rest are half the size too.

    EF = 1.5

    DF = 2
