Answer:

Choice D:

π/2, 3π/4, 5π/4, and 7π/4

Step-by-step explanation:

correct on edg

The solution of the equation y = cos(2x) will be π/4, 3π/2, 5π/4, and 7π/4. Then the correct option is D.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The equation is given below.

y = cos(2x)

The x-intercept of the equation in the interval 0 ≤ x < 2π will be given as,

y = 0

cos(2x) = 0

cos 2x = cos (n + 1) π/2

2x = (n + 1)π / 2

x = (n + 1)π / 4

x = π/4, 3π/2, 5π/4, 7π/4

The solution of the equation y = cos(2x) will be π/4, 3π/2, 5π/4, and 7π/4. Then the correct option is D.

Answer:

each person would getb3 dollars back

Step-by-step explanation:

since each friend pays $10 and there are 4 friends the total is 40 but now you have to do $40.00 minus $25.00 because of tax and gratuity so when you do that you get $15.00 now you have to do 15 ÷ 4 and that equals $3.75 and since you cant divide 75 coins to 4 people we dont add that but now you have your answer each friend gets $3.00

The mass per cup for the objects will be 320g and 272g respectively.

Mass simply means the weight that an object contains.

The mass of a teapot and 4 cups is 1,280 grams. The mass per cup will be:

= Mass / Number of cups

= 1280 / 4

= 320g

The mass of the same teapot and 10 cups is 2,720 grams. The mass per cup will be:

= 2720 / 10

= 272g

Let's break this down...

9.03+10.71 is 19.74 and subtracted by 6.8 it will be 12.94 not 13.94 so it is not correct

So the answer is No

Hope this helps!

Answer:

No, it is 12.94

Step-by-step explanation:

9.03 + 10.71 = 19.74, 19.74 - 6.8 = 12.94

Answer: Yes you can but it would be the same as dividing 10 by 3, it would just be a repeating fraction

Step-by-step explanation:

The Volume of a Sphere

The volume of a sphere of radius r is given by:

[tex]\displaystyle V=\frac{4}{3}\cdot \pi\cdot r^3[/tex]

The radius of the sphere is r=7 cm, thus:

[tex]\displaystyle V=\frac{4}{3}\cdot 3.14\cdot 7^3[/tex]

[tex]V=1436.03 \ cm^3[/tex]

Note: We have used an approximated value for pi=3.14.

The volume of the sphere rounded to the nearest hundredth is

[tex]\boxed{V=1436.03 \ cm^3}[/tex]

The second choice provides the correct answer.

She can select the bridesmaids' dress in 140 possible ways.

Permutation represents each of the several possible ways in which a set or number of things can be ordered or arranged.

Given is a bride who is choosing a dress for her bridesmaids which are available in 4 styles, 7 colors, and 5 fabrics.

Now, for every possible style there exist a dress for that color. So, with 4 styles and 7 colors, the total number of possible dresses will be = 7 x 4 = 28. Now, for these 28 dresses, their are 5 different fabric available, so the total number of possible ways or dresses from which she can select the dress are = 28 x 5 = 140

Therefore, she can select the bridesmaids' dress in 140 possible ways.
