It is true

Answer:

Yes

Step-by-step explanation:

1,4 the first coordinate is X and the second is Y so it means y = 4 and X = 1

So that means the equation becomes 4 = 4 times 1 which is correct since 4 times 1 is 4 and 4=4

7+6(8)

7+48

55

Answer:

7+ 6 x 8

Step-by-step explanation: Since c=8 you will basically replace the c with the 8 and you do the same with the 7 , d=7 so you replace d with a 7 and when you have a variable (x or another letter)  next to a number you multiply so you get  7 + 6 x 8

(the x = multiplying)

Answer:

1) Cos

2) 1

3) π

4) 1

5) y < 0

Step-by-step explanation:

1)

Cos

2)

The y-intercept is the value of y when x=0, ie the value of y when the line meets the y-axis. We can see from the graph that this is 1.

3)

The x-intercept is the value of x when y=0, ie the value of x when the line meets the x-axis. We can see from the graph that the smallest positive value of x when the line crosses the x-axis is π.

4)

Highest y value from graph is 1, and besides, for cos graphs, y≤1.

5)

We can see from the graph that between x=π and x=2π, the function is bellow the y-axis, ie y<0.

The graph is of a cos function. The y-intercept of the graph is the function value y=1. The smallest positive x-intercept of the graph is located at x=π. The greatest value of y is y=1, and it occurs when x=2π. For x between x = π and 2π, the function value y<0.

The point on the graph where it crosses the y-axis is known as the y-intercept. The y-intercept in this situation is zero since the graph crosses the y-axis at (0, 0).

The point at which the graph first crosses the x-axis at a positive value of x is known as the graph's smallest positive x-intercept. The graph in this instance crosses the x-axis at (x,0), making the smallest positive x-intercept.

The maximum value of the function is equal to the highest value of y. The greatest value of y in this situation is 1, and it happens when x = 2.

The function value y declines from 1 to 0 for x between x = and 2. You can observe this by examining the graph.

Answer:

Step-by-step explanation:

f(n)=30n

domain all real numbers

range all real numbers

I think.

Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.

A relation is a function if it has only One y-value for each x-value.

The function that relates the total number of minutes practiced, p, to the number of practice days, n, is given by:

p = 30n

where 30 is the number of minutes Elena practices each day.

Since we cannot have negative practice days, the domain of the function is the set of non-negative integers:

Domain: {0, 1, 2, 3, ...}

The range of this function is the set of all possible values of p that can be obtained by plugging in values of n from the domain.

In this case, since the function only outputs non-negative values, the range is the set of non-negative integers:

Range: {0, 30, 60, 90, ...}

Hence, Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.

12 divided by 1/10

Step-by-step explanation:

12 divided by 1/10 would become 12 times 10 because you can't divide by a fraction, so you put the denominator on top and numerator on the bottom, which would become 10 and then multiply.
