Answer:

Which subject is optional in the morning??

Answer:

Your answer is 211.8

Step-by-step explanation:

We've made a right triangle so the equation is a²+b² = c²

141²+158² = c²

141²+158² = 44845

Then you square root it

√44845 = 211.8

Answer:

Here we want to solve:

(cos(A) + sin(A))^2 + ( sin(A) - cos(A))^2 = 2

First, remember the two expansions:

(a + b)^2 = a^2 + 2*a*b + b^2

(a - b)^2 = a^2 - 2*a*b - b^2

Using these relations, we can expand:

(cos(A) + sin(A))^2 = cos(A)^2 + 2*cos(A)*sin(A) + sin(A)^2

( sin(A) - cos(A))^2 = sin(A)^2 - 2*sin(A)*cos(A) + cos(A)^2

Replacing that in our equation, we geT:

(cos(A)^2 + 2*cos(A)*sin(A) + sin(A)^2) + (sin(A)^2 - 2*sin(A)*cos(A) + cos(A)^2) = 2

We can simplify this to get:

2*cos(A)^2 + 2*sin(A)^2 + 2*cos(A)*sin(A) - 2*cos(A)*sin(A) = 2

2*cos(A)^2 + 2*sin(A)^2 = 2

We can take the 2 as a common factor to get:

2*cos(A)^2 + 2*sin(A)^2 = 2*( cos(A)^2 + sin(A)^2) = 2

Now we can divide both sides by 2:

2*( cos(A)^2 + sin(A)^2)/2 = 2/2

cos(A)^2 + sin(A)^2 = 1

And this is a trigonometric property that is true for any value of A.

So the equality:

(cos(A) + sin(A))^2 + ( sin(A) - cos(A))^2 = 2

is true for any real value of A.

Option B, the y-intercept changes

Explanation:

This is because, the y-intercept is located on the y-axis, which is the vertical axis, moving the graph up and down would mean moving it vertically, therefore this would result in the change of the y-intercept.

Continuous: g(x) and j(x)

Removable: h(x) and m(x)

Infinite: f(x) and i(x) and k(x)

Jump: l(x)

Step-by-step explanation:

Continuous: g(x) and j(x), Removable: h(x) and m(x), Infinite: f(x) and i(x) and k(x) & Jump: l(x)

A function is a relation among a fixed of inputs and a fixed of permissible outputs with the belonging that each input is associated with exactly one output. permit A & B to be any non-empty units, mapping from A to B might be a feature most effective while every detail in set A has one give up handiest one picture in the set.

The eight sorts are linear, strength, quadratic, polynomial, rational, exponential, logarithmic, and sinusoidal.

One to 1 characteristic or one to at least one mapping states that each detail of one set, say Set is mapped with a completely unique element of another set, say, Set in which A and B are distinctive units.

f(x) = f(y) implies x  then f is one to at least one.

Step-by-step explanation:

2x x(x-1) = x x (x+4)

2x x (x-1) - x x (x+4)= 0

2x^2 - 2x - x x (x+4) = 0

2x^2 - 2x - x^2 - 4x = 0

x^2 - 2x - 4x = 0

x^2 - 6x = 0

x x (x-6) = 0

x = 0

x - 6 = 0

x = 6

The equation has 2 solutions

Number line model represented in option C represents the expression 6 + (-2).

Number line is a pictorial representation of numbers, both negative and non-negative numbers, written on a horizontal straight line within specific intervals.

Number line are used to determine basic mathematical operations like addition, subtraction, division and multiplication.

So here, we are adding the value -2 with 6.

First draw an upward arrow from 0 to 6 in order to represent that we are initiating the addition process with 6.

Then the number -2 added to 6 implies that the number 2 is actually deducting from 6.

So we draw a downward arrow to unit units from 6.

Then we get the number 4 corresponding to the point where the arrow ends.

Hence, option C is the model which represents the expression 6 + (-2).

Answer: √ 52

Step-by-step explanation:

Answer:

length :16cm

wide :20cm

We have

Area of inner frame :16*20=320cm²

For

Total area =464cm²

(20+2x)(16+2x)=464cm²

320+32x+40x+4x²=464cm²

4x²+72x+320-464=0

4x²+72x-144=0

4(x²+18x-36)=0

x²+2.9.x+9²=9²+36

(x+9)²=117

x+9=√117

x=10.81-9

x=1.82[approximately]

So

width of frame;20cm+1.82+1.82=23.64cm

length: 16+1.82+1.82=19.64cm

Here length is smaller than breadth.
