Solve for x. Round your answer to the nearest tenth (0.1)
Marizza181 [45]

Answer:

x\approx 7.0

Step-by-step explanation:

Since we are given a right triangle, we can use right trigonometric ratios.

<em>x</em> is the opposite side to our angle. 10 is the adjacent side to it. Thus, we can use the tangent ratio:

\displaystyle \tan(\theta^\circ)=\frac{\text{opposite}}{\text{adjacent}}

Substitute:

\displaystyle \tan(35^\circ)=\frac{x}{10}

Solve for <em>x:</em>

<em />x=10\tan(35^\circ)<em />

Use a calculator:

x=7.0020...\approx 7.0

Translate each English phrase in the following problem into an algebraic expression and set up the related equation. Let z be th
Ede4ka [16]

The English phrase of the obtained equation is 12 times z subtracted by 3. The obtained equation after solving is 12z -23

<h3>What exactly is simplification?</h3>

Simplifying means making something easier to do or comprehend, as well as making something less difficult.

Given data;

z be the unknown number

Given conditions;

1. The difference between a number and −23.

2.−23 is equal to the product of the number and 13.

The mathematical form of the given phrase is;

⇒ z - (-23) = z × 13

⇒z+23 = 13z

⇒12z -23

The English phrase of the obtained equation is 12 times z subtracted by 3.

Hence the simplification of the given expressions is 12z -23.

The assets (in billions of dollars) for a financial firm can be approximated by the function A(x)=318e^0.27x, where x=7 correspo
Mashutka [201]

The value of the asset in 2012, 2014, and 2017 are 8119.72, 13933.55 and, 31321.23, respectively. A function assigns the values.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Given the assets (in billions of dollars) for a financial firm can be approximated by the function A(x)=318e^{0.27x}, where x=7 corresponds to the year 2007. Therefore, the assets value in the following years will be,

A.) 2012 - A(12)=318e^{0.27\times 12} = 8,119.72

B.) 2014 - A(14)=318e^{0.27\times 14} = 13,933.5

C.) 2012 - A(17)=318e^{0.27\times 17} = 31,321.23

Hence, the value of the asset in 2012, 2014, and 2017 are 8119.72, 13933.55 and, 31321.23, respectively.
