Answer:

Step-by-step explanation:

Using the law of Sines in ΔABC

$\frac{a}{sinA}$ = $\frac{c}{sinC}$ , that is

$\frac{37}{sin42}$ = $\frac{c}{sin41.5}$ ( cross- multiply )

c × sin42° = 37 × sin41.5° ( divide both sides by sin42° )

c = $\frac{37(sin41.5)}{sin42}$ ≈ 36.64 ( to 2 dec. places )

➷ a/sinA = c/sinC

Substitute in the values:

37/sin(42) = c/sin(41.5)

Multiply both sides by sin(41.5)

37/sin(42) x sin(41.5) = c

Solve:

c = 36.63999457

The correct answer would be C. 36.64

If x, y, and z are integers greater than 1, and (327)(510)(z) = (58)(914)(xy), then what is the value of x?

algol [13]

Answer:

Statements (1) and (2) TOGETHER are NOT sufficient.

Explanation:

As in the equation (327)(510)(z) = (58)(914)(xy) there are THREE variables in total i.e. "x", "y" and "z" hence minimum three equations are required to find out values of all variables. Hence,

If the given number of equations is equal to total variable used in any of the equation, values of all the variables can be find out otherwise there can be unlimited number of solutions.

So, value of "x" cannot be determined with the given data.

What are the zeros of the function defined by 2x + 11x- 6?

asambeis [7]

Note --> As you're writing 'zeroes' , I assume there is a typing mistake and you've given a Quadratic equation in the question

$f(x) = 2 {x}^{2} + 11x - 6 \\ \\ f(x) = (2x - 1)(x + 6) = 0$

Hence , the roots are 1/2 and -6
The graph attached confirms the same ,

Hope it helps you :)

PLEASE SOLVE AND CHECK. SHOW COMPLETE SOLUTION

Answer:

-2/3= x

Step-by-step explanation:

square all the terms on both sides to get rid of the radicals:

$1^{2} + (\sqrt{1-x} )^{2} = (\sqrt{2x+4}) ^{2}$

exponent 2 and the radical cancel each other:

1 + 1 - x = 2x + 4

2 - x = 2x + 4

like terms on each side ( when you move one term tp the other side, it changes its sign ):

2-x = 2x+4

2-4 = +x +2x

-2 = 3x

now to keep the x alone, divide both sides by 3:

-2/3 = 3x/3

-2/3= x
