\begin{gathered}\\ \sf\longmapsto cos(x+1)\end{gathered}

Use cos(t+s)=cos (t)cos (s)- sin(x)sin (1)

\begin{gathered}\\ \sf\longmapsto cos(x)cos(1)-sin(x)sin(1)\end{gathered}

\boxed{\sf cos(A+B)=cosAcosB-sinAsinB}

Now

\\ \sf\longmapsto cos(x+1)

  • A=x
  • B=1

\\ \sf\longmapsto cosxcos(1)-sinxsin(1)

Jenny has 50 square tile she arranges the tiles into a recatugular array of 4 rows. how may tile will be left over?"
Hatshy [7]
Well if you have four rows, then you could put them in four groups of twelve. 12 times 4 is 48, meaning you would have two left over.

Draw a model. Then, write the numerical expressions.
kondor19780726 [428]

Answer with Step-by-step explanation:

a. The difference between 8 forty-sevens and 7 forty-sevens

Let ⊕ repesents forty- sevens.

So, Model can be represented by

8⊕ - 7⊕

=⊕⊕⊕⊕⊕⊕⊕⊕-⊕⊕⊕⊕⊕⊕⊕

=⊕

Mathematically,

let x represents forty-sevens.

So, it becomes

8x-7x=x

b. 6 times the sum of 12 and 8.

Mathematically, it is expressed as

6\times (12+8)\\\\=6\times 20\\\\=120

Let 12 be written as 4×3

and 8 be written as 4×2

Let ⊕ represents 4 i.e. fours.

so, there are sum of 2 fours and 3 fours.

So, it becomes,

6×(⊕⊕+⊕⊕⊕)

=6×(⊕⊕⊕⊕⊕)

=⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕⊕

=4×30

=120

The dimensions of the computer screen are modeled by the equation x2 + (x – 4)2 = 202. What is the value of x, the length of the
Mars2501 [29]

Answer:

x = 11.85

Step-by-step explanation:

x^2+(x-4)^2=202

x^2+(x-4)(x-4)=202

x^2 + x^2 - 4x - 4x + 16 = 202

2x^2 - 8x + 16 = 202

2x^2 - 8x - 186 = 0

Apply the quadratic equation and you'll get x as:

x=11.85 or x=-7.85

x cannot be negative

therefore x = 11.85

On a coordinate plane, a circle has a center at (negative 2, 0). Point (negative 2, 4) lies on the circle.
wlad13 [49]

The correct answer to where the point(1, StartRoot 7 EndRoot) lies on the circle is A. Yes, the distance from (–2, 0) to (1, StartRoot 7 EndRoot) is 4 units

<h3>What is a Coordinate Plane?</h3>

This refers to the tool that is used to graph points on a two-dimensional plane that intersects two number lines.

Hence, given the information in the given diagram, there is a coordinate plane that shows a circle at the center that has certain values on the y and x-axis.

We can state that the point (1, StartRoot 7 EndRoot) lies on the circle shown because the distance from (–2, 0) to (1, StartRoot 7 EndRoot) is 4 units.
