GIVING OUT BRAINLIEST ANSWER HELP PLSSSS

Mathematics

velikii [3]4 years ago

Answer:

x = 63.43...

Step-by-step explanation:

Ok, so the angle x is the same measure as the bottom right angle of the triangle because the bottom of the triangle and the dashed line are parallel. Knowing this we can simply solve for the bottom right angle and it will be the same as angle x.

To do this we can set up and equation with tangent because we are working with the opposite and adjacent sides of the triangle.

Tan(x) = \frac{opposite}{adjacent} = \frac{50}{25} = 2

Tan(x)=2\\

Now to isolate the variable, we can simply use the cotangent or inverse tangent.

Tan^{-1}(Tan(x)) = Tan^{-1}(2)\\x = Tan^{-1}(2)\\x = 63.43...

Nataly [62]
The population of Oak Forest is increasing at a rate of 4% per year.

Increase rate, r = 4%

Current population, P = 39,410

time, t = 3 years

Population after 3 years will be:
P{(1 + \frac{r}{100} )}^{t} \\ \\ = 39410 \times { ( 1 + \frac{4}{100} )}^{3} \\ \\ = 39410 \times {1.04}^{3} \\ \\ = 44330.89 \\ \\ \approx \boxed{44331}

Population after 3 years will be 44331

Jordan was given the expression 2x2^-3 x 2^-5 How should he write the expression as a fraction? Describe the exponent rules Jord
mariarad [96]

Answer:

2*2^{-3} * 2^{-5} =\frac{1}{128}

Step-by-step explanation:

Given

2*2^{-3} * 2^{-5}

Required

Write as a fraction

To do this, Jordan has to apply the following rules

<u>Negative Exponent rule:</u>

a^{-m} = \frac{1}{a^m}

<u>So, the expression is:</u>

2*2^{-3} * 2^{-5} = \frac{2}{2^3 * 2^5}

<u>To solve further, we apply the product rule of exponent</u>

a^m * a^n = a^{m+n}

<u>So, the expression is:</u>

2*2^{-3} * 2^{-5} =\frac{2}{2^{3+5}}

2*2^{-3} * 2^{-5} =\frac{2}{2^8}

<u></u>

<u>Evaluate the exponents</u>

2*2^{-3} * 2^{-5} =\frac{2}{256}

<u>Divide the numerator and denominator by 2</u>

2*2^{-3} * 2^{-5} =\frac{2/2}{256/2}

2*2^{-3} * 2^{-5} =\frac{1}{128}
