What is the value of cose in the diagram below?

Nuetrik [128]

Answer:

$cos \theta = 0.6$

Step-by-step explanation:

Draw a line from point ( 0.6, 0.8 ) to the X - axis, forming a right triangle with hypotenuse = r = 1 , adjacent = 0.6, opposite = 0.8

$cos \theta = \frac{adjacent}{hypotenuse} , \ where \ adjacent = 0.6 ,\ hypotenuse \ = r= 1$

$cos \theta = \frac{0.6}{1}\\\\cos \theta = 0.6\\\\\theta = cos^{-1} \ 0.6\\\\\theta = 53.13^\circ$

Madame Dubois bought 20 pearl necklaces for $500. Becoming bored quickly, she sold 3/4 of them at $40 each. She sold the rest at

Serjik [45]

1. Which of the following will simplify to the<br> correct solutions of y = 2x2 + 5x - 7?

natka813 [3]

Answer:

Option B

Step-by-step explanation:

Given quadratic equation is,

y = 2x² + 5x - 7

By comparing this equation with y = ax² + bx + c

a = 2, b = 5 and c = -7

Solution of the polynomial (2x² + 5x - 7) can be determined by the quadratic formula,

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

Substitute the values of a, b and c.

$x=\frac{-5\pm \sqrt{5^2-4(2)(-7)}}{2(2)}$

$=\frac{-5\pm \sqrt{25+56} }{4}$

Therefore, Option B will be answer.
