How do you use cos on the calculater in math
Veronika [31]

Answer:First make sure your calculator is on the right setting which would be a DEG. Then depending on the problem you would press COS, put whats needed inside the parentheses and close it.

Or if a different kind of problem you would press 2nd on the top of the calculator then Cos and continue the same way as the first one.

It’s really confusing, I could really use some guidance.
Dafna1 [17]

Answer:

See below.

Step-by-step explanation:

Let x equal each of the values on the table, and find the value of the function for that value of x.

f(x) = 5x - 5

x = -4

f(-4) = 5(-4) - 5

f(-4) = -20 - 5

f(-4) = -25

x = 0

f(0) = 5(0) - 5

f(0) = 0 - 5

f(0) = -5

x = 1

f(1) = 5(1) - 5

f(1) = 5 - 5

f(1) = 0

x = 3

f(3) = 5(3) - 5

f(3) = 15 - 5

f(3) = 10

x = 5

f(5) = 5(5) - 5

f(5) = 25 - 5

f(5) = 20

x          f(x)

-4        -25

0          5

1           0

3          10

5          20

Question 4
Snowcat [4.5K]

Answer:

a is 7/25

b is 14/25

c is 24

Step-by-step explanation:

a) because there are 25 possible outcomes and 7 of them are 3 it is 7/25

b) using the same logic 14 possible outcomes are even

c) because the probability of it being 2 is 3/25, which can be made into ?/200 by multiplying the 25 by 8, which means we have to do the same to the 3, making it 24
