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:

If you mean h multiplied by 26 is -52 then h is -2

If it is added to 26 then h is -78

If it is subtracted then h is -26

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:

- $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]

Step-by-step explanation:

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.

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°.
