Answer:

Angles 1 and 2 are Complementary angles

Step-by-step explanation:

There is probably some vocabulary is your lesson, but from my knowledge, these angles would be complementary because they add up to 90 degrees total. Complementary angles are either of two angles that add up to 90 degrees, since it is shown that the other three angles besides these two are 90 degrees (thats what the square signifies), then these two angles have to add up to 90 degrees as well which will make them complementary.

If 12 children represents 12.5% of the people attending a concert, how many people are attending the concert

NeTakaya

96 people are attending the concert.

Step-by-step explanation:

Given,

Number of children at concert = 12

This represents 12.5% of the people attending concert.

Let,

p be the total people attending concert.

12.5% of p = 12

$\frac{12.5}{100}*p=12\\0.125p=12$

Dividing both sides by 0.125

$\frac{0.125p}{0.125}=\frac{12}{0.125}\\p=96$

96 people are attending the concert.

What are the explicit equation and domain for a geometric sequence with a first term of 2 and a second term of −8?

Alexxx [7]

The common ratio in a geometric sequence is the ratio between 2 consecutive terms:

-8/2=-4,

then the sequence is 2, -8, 32, -128, -512, 2048, ...

let $a_n$ be the nth term of the sequence, then

$a_1= 2$
$a_2=2(-4)$
$a_3=2(-4)(-4)=2(-4)^{2}$
$a_4=2(-4)(-4)(-4)=2(-4)^{3}$
.
.
.
so clearly $a_n=2(-4)^{n-1}$

and, clearly n are integers >0, since we have a 1st term, a second term and so on... of a sequence (we do not have a "zero'th term"!

Answer:

<span>C. an=2(-4)^n-1; all integers where n>0</span>

Find the measure of the largest angle.

mihalych1998 [28]

Answer:

4x-7

Step-by-step explanation:

Solve for x:

180 = 44 + 3x - 11 + 4x - 7

Combine like terms: 180 = 26 + 7x

Simplify: 154 = 7x

Simplify: 22 = x

Substitute: 3(22) - 11 = 55 and 4(22) - 7 = 81

Create inequality: 44 < 55 < 81
