Answer:

30 = <8

Step-by-step explanation:

<4 and <8 are corresponding angles and corresponding angles are equal when the lines are parallel

<4 = <8

30 = <8

Hey there! :)

Answer:

m∠8 = 30°.

Step-by-step explanation:

Since AB || CD, m∠4 = m∠8 because they are corresponding angles. Therefore:

If m∠4 = 30°, m∠8 = 30°.

f(x) = 2^(4x)

g(x) = 2^x

(fg) = 2^4x * 2^x = 2^5x

NOTE: When multiplying two powers with same base exponents add.

(f/g)(x) = (2^4x)/(2^x) = 2^3x

NOTE: And when dividing they subtract.

Answer: a and c

frozen [14]

Question:

The geometric sequence ai is defined by the formula: a₁ = 8, aᵢ = aᵢ₋₁(-1.5 ).

Find the sum of the first 20 terms in the sequence. Choose 1 answer:

Answer:

The sun of 20 terms of the progress is -10,637.621536256

Step-by-step explanation:

Given

Geometric Sequence

a₁ = 8

aᵢ = aᵢ₋₁(-1.5 )

First, the common ratio needs to be calculated.

The common ratio is the ratio of a term to its previous term.

In other words,

Ratio = 2nd term ÷ 1st term or 3rd term ÷ 2nd term, ...... Etc.

We can calculate the common ratio from aᵢ = aᵢ₋₁(-1.5 ) by dividing both sides by aᵢ₋₁. This gives

aᵢ / aᵢ₋₁ = aᵢ₋₁(-1.5 ) / aᵢ₋₁

aᵢ / aᵢ₋₁ = -1.5

So, the common ratio, r = -1.5

Now that we've had the common ratio and first term to be -1.5 and 8 respectively, the sum of 20 terms can then be calculated using the sum of n terms formula.

Sₙ = a(1 - rⁿ)/(1 - r)

We're making use of this formula because r is less than 1

Where n = 20

a = first term = 8

r = -1.5

By substituting these values; we get

S₂₀ = 8(1 - (-1.5)²⁰)/(1 - (-1.5))

S₂₀ = 8(1 - (-1.5)²⁰)/(1 + 1.5))

S₂₀ = 8(1 - (-1.5)²⁰)/(1 + 1.5))

S₂₀ = 8(1 - (3325.25673008

))/(2.5)

S₂₀ = 8(1 - 3325.25673008

)/(2.5)

S₂₀ = 8(-3324.25673008

)/(2.5)

S₂₀ = -10,637.621536256

Determine if true:<br> 1y+8y+10y=20y
diamong [38]

Answer:

False

Step-by-step explanation:

1+8=9

9+10=19

1y+8y=9y

9y+10y=19y

19y=20y

The equations dont match.

Hence, the equation is false.
