Answer:

C. 7.8

Step-by-step explanation:

This problem involves the use of a trigonometric ratio. This one specifically involves the use of cosine as it provides the leg adjacent to the angle and the hypotenuse.

cos(40) = 6/x

cos(40)*x=6/x*x

cos(40)*x=6

cos(40)/cos(40)*x=6/cos(40)

x=6/cos(40)

x=7.83

The value of x is C. 7.8

Answer:

25

Step-by-step explanation:

The increments are 0.4, and the width of the interval is 10, so the number of increments (the number of times you need to use Euler's method) is:

10 / 0.4 = 25

A 12 foot by 8 foot rug covers the hardwood floor of a room. The rug leaves a uniform
trapecia [35]

Answer: 2(12 × 8)

Step-by-step explanation:

The area of the rug will be gotten by multiplying the length by its width. This will be:

= 12 foot × 8 foot

= 96feet²

Since the area of the room is twice the area of the rug, the equation you will use to solve for x will be:

= 2(12 × 8)

= 2(96)

= 192feet²

First, we are going to find if the function is odd or even. Remember that we can determine if a function is odd of even from its graph by looking at its ends; if both ends go to the same the direction, the function is even. If both ends go to opposite directions, the function is odd. At both ends, the graph of our function go towards the same direction, minus infinity, so we can conclude that our function is even.

Next, we are going to find the possible degree of our function. Remember that the possible degree of a function is the number of x-intercepts.
We can infer from our graph that the function intercepts the x-axis at least 6 times.

We can conclude that the correct answer is: even degrees of 6 or greater.
