What is the length of the side labeled x?

Mathematics

Scorpion4ik [409]2 years ago

Answer:

AB = 42.15 units

Step-by-step explanation:

In triangle ABD,

By applying Cosine rule in this triangle,

cos(30)°= \frac{\text{Adjacent side}}{\text{Hypotenuse}}

\frac{\sqrt{3} }{2} = \frac{AD}{AB}

\frac{\sqrt{3}}{2}=\frac{AD}{47}

AD = \frac{47\sqrt{3}}{2}

By applying tangent rule in ΔACD,

tan(44)° = \frac{\text{Opposite side}}{\text{Adjacent side}}

tan(44)° = \frac{AD}{x}

0.9657 =  \frac{\frac{47\sqrt{3}}{2}}{x}

0.9657 = \frac{47\sqrt{3}}{2x}

x = \frac{47\sqrt{3}}{2(0.9657)}

x = 42.15

  ≈ 42.2 units

Identify az of this sequence: 0.25, 0.5, 0.75, 1, 1.25. 1.5
4vir4ik [10]
<h3><u>Question:</u></h3>

Identify a3 of this sequence: 0.25, 0.5, 0.75, 1, 1.25, 1.5,...a3=

<h3><u>Answer:</u></h3>

The third term of sequence is 0.75

a_3 = 0.75

<h3><u>Solution:</u></h3>

Given that, sequence is:

0.25, 0.5, 0.75, 1, 1.25. 1.5

Let us find the difference between terms

0.5 - 0.25 = 0.25\\\\0.75-0.5 = 0.25\\\\1.25-1=0.25\\\\1.5-1.25=0.25

This is a arithmetic sequence

Because the difference between any term and its immediately preceding term is always 0.25

In a arithmetic sequence,

a_1 = \text{ first term of sequnece }\\\\a_2 = \text{second term of sequnce }\\\\a_3 = \text{third term of sequnece }\\\\a_n = \text{ nth term of sequnce }

Thus, in the sequence 0.25, 0.5, 0.75, 1, 1.25. 1.5

a_3 = \text{ third term } = 0.75

Thus the third term of sequence is 0.75

What is the value of b in the equation (y)*
KonstantinChe [14]

Answer:

b = -6

Step-by-step explanation:

Apply the exponent rule that   \frac{1}{x^{n}} = x^{-n}

In this case, \frac{1}{y^{24}}  = y^{-24}

Set that equal to (y^{b})^{4}:

(y^{b})^{4} = y^{-24}

Apply the exponent rule that (x^{m})^{n} = x^{mn} so now you get:

y^{4b} = y^{-24}

Since the base is y for both sides of the equation, just set the exponents equal to each other and solve for b.

4b = -24

divide each side by 4 to get:

b = -6
