Should be P(A∩B)=P(A)⋅P(B)

The pair of trigonometric functions that are equivalent is cos76°, sin14°.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

We know sin(π/2 - Ф) = cosФ and cos(π/2 - Ф) = sinФ.

sin23° = cos(90° - 23°) = cos67°.

cos41° ≠ sin41°.

cos58° = cos(180° - 58°) = cos122°.

cos76° = sin(90° - 76°) = sin14°.

Answer:

28 meters wide

Step-by-step explanation:

This involves using the Pythagorean Theorem.

We know: a (the length)=96, b (the width)=?, c (diagonal distance)=100

a^2+b^2=c^2

96^2+b^2=100^2

9216+b^2=10000

b^2=784

b=28

The field is 28 meters wide

Step-by-step explanation:

The segment AC is the angle bisector of angle BAD and angle BCD.

A ray, segment, or line that divides a given angle into two equal angles is known as an angle bisector.

When something is bisected or bisected, it is split into two equal sections. In geometry, an angle bisector is a line or ray that divides a triangle into two equal angles.

here, we have,

Given that ΔABC ≅ ΔADC Prove: AC bisects ∠BAD and AC bisects ∠BCD​

From the given data it is concluded that all the corresponding angles of the triangle are equal to each other.

In the triangle ABC and ADC:-

∠BAC = ∠DAC

∠BCA = ∠DCA

From the above proof, it is concluded that the AC bisects ∠BAD and ∠BCD.

Therefore, the segment AC is the angle bisector of angle BAD and angle BCD.

Answer: It is a function.

Step-by-step explanation:

A function is a relation between two sets that associates every element of the one set to exactly one element of the other set.

Given table :  Input values    Output values

                             -3                         6

                                5                        6

                                  3                      -2

                                 -5                         1

Here each input value value is related to exactly one out out value.

Hence, it is a function.

Answer:

- $5.5 per pound

- [tex]y = 5.5x[/tex]

Step-by-step explanation:

Given

$11 for 2 pounds

Solving (a): Cost per pound

This is calculated by dividing $11 by 2 pounds

[tex]Cost\ per\ pound = \frac{\$11}{2\ lb}[/tex]

[tex]Cost\ per\ pound = \$5.5/\ lb[/tex]

Hence, the cost per pound is $5.5 per pound

Solving (b): Represent as an equation.

If 1 pound costs $5.5 (as shown in (a))

Then

x pounds costs $5.5 * x

[tex]Cost = 5.5 * x[/tex]

[tex]Cost = 5.5x[/tex]

This cost is represented with y

[tex]y = 5.5x[/tex]

14 integers

Step-by-step explanation:

Given

[tex]Range: -6.01\ to\ 7.75[/tex]

Required

Determine the number of integers

Integers implies numbers without decimals; it could be positive or negative or 0.

So, within the range: the integers are:

[tex]-6, -5, -4,-3,-2,-1,0,1,2,3,4,5,6,7[/tex]

Notice that the above numbers are integers within the given range.

By counting them, we get the required number of integers.

[tex]Numbers = 14[/tex]

Hence, there are 14 integers

Answer:

216 x^3 - 540 x^2 + 450 x - 125 = (6 x - 5)^3

Step-by-step explanation:

The first one cannot be a perfect cube, since the first term contains x^2 and not x^3.

the second one is not a perfect square (the coefficient of the middle term should be an even number: "-90")

The third expression is the perfect cube as shown.

Answer:

x = 90

y = 43

Step-by-step explanation:

[tex] In\: \triangle ABC\\

AB = AC.... (given)

\therefore m\angle ABC = m\angle ACB\\[/tex] (Property of isosceles triangle)

[tex] \because m\angle ACB = 47\degree \\

\therefore m\angle ABC = 47\degree \\

2y\degree + 47\degree+47\degree = 180\degree \\

2y\degree + 94\degree= 180\degree \\

2y\degree = 180\degree - 94\degree \\

2y\degree = 86\degree \\\\

y = \frac{86\degree}{2} \\\\

y\degree = 43\degree \\\\

\huge \purple {\boxed {y = 43}} \\\\[/tex]

x° + y° + 47°=180°

x° + 43° + 47°=180°

x ° + 90° = 180°

x ° = 180° - 90°

x° = 90°

x = 90
