The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. The value of x is 6.2 units.

The tangent or tanθ in a right-angle triangle is the ratio of its perpendicular to its base. it is given as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

The base is the adjacent smaller side of the angle θ.

The value of x is,

x = AB - AC

x = 31(Tan 37°) - 31(Tan 29°)

x = 6.17659 ≈ 6.2 units.

Hence, the value of x is 6.2 units.

Step-by-step explanation:

whenever there is negative number being squared, you need to add the brackets so that you inside the - 1 in front of the number

so this step is wrong

[tex] \sqrt{ - 9 { }^{2} - 4(1)(20) } [/tex]

the -9 ² , you must include the brackets to include the -1 in front of the 9

so it should be

[tex] \sqrt{( - 9) {}^{2} - 4(1)(20) } [/tex]

so you will get = 1

and then you continue with other parts of the formula and you will get real solutions

Answer and Step-by-step explanation:

f(n) = 45 - 4(n - 1)

This is the explicit formula for the sequence.

45 is the initial amount, which is why it is by itself.

The change in the sequence is take away 4, so this becomes a negative 4, which is then multiplied by (n - 1), where n is the term in the sequence.

Answer:

x = -4 and y = -20

Step-by-step explanation:

y = 5x and 7x - 3y = 32

→ Substitute y = 5x into 7x - 3y = 32

7x - 15x = 32

→ Simplify

-8x = 32

→ Solve

x = -4

→ Substitute x = -4 into y = 5x

5 × -4 = -20

Answer: 2/21

Step-by-step explanation:

5[5y -6] = 4[y -7]

We first need to open the bracket to be able to solve the question

25y - 30 = 4y - 28

Collect like terms

25y - 4y = -28 + 30

21y = 2.

y = 2/21

Therefore, the value for y is 2/21.

Answer:

Step-by-step explanation:Because many objects are not regularly shaped their volume cannot be determined using a volume formula. The volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.
