What is the approximate value of x in the diagram below? (Hint: You will need

Delicious77 [7]

Answer:

B. 39.59

Step-by-step explanation:

So 43 degrees, you know the length of the opposite side (27) and the angle (43 degrees), the only unknown is the hypotenuse. So you're looking for a trigonometric ratio that uses the angle (all of them do, except technically the inverse don't), the opposite side, and the hypotenuse. Sine is defined as $\frac{opposite}{hypotenuse}$ . So let's plug in known values:

$sin(43) = \frac{27}{x}$

Multiply both sides by x

$sin(43) * x = 27$

divide both sides by sin(43)

$x=\frac{27}{sin(43)}$

Normally I would use a calculator, but in this case I'll use the approximation given in the problem of 0.682

$x=\frac{27}{0.682}$

simplify the fraction

$x\approx39.59$

43.77 as a mixed number in simplest form

valina [46]

First you have to take the whole number (43) and then take the decimal and put it over 100 (77/100).

Simplify the following expression: (5x2 + 3x + 4) − (2x2 + 7x − 1). If the final answer is written in the form Ax2 + Bx + C, wha

Andrews [41]

Answer:

3x + 2x2 + 4 = 5

3x + 2x2 + 4 – 5 = 5 – 5

First be sure that the right side of the equation is 0. In this case, all you need to do is subtract 5 from both sides.

3x + 2x2 – 1 = 0

2x2 + 3x – 1 = 0

Simplify, and write the terms with the exponent on the variable in descending order.

ax2

a = 2, b = 3, c = −1

Now that the equation is in standard form, you can read the values of a, b, and c from the coefficients and constant. Note that since the constant 1 is subtracted, c must be negative.

Answer

2x2 + 3x – 1 = 0; a = 2, b = 3, c = −1
