Simipified the exprestion -1.7+(-6.3).On the test when maureen simipified the exression she got -4.6. What mistake did maureen l

Rasek [7]

Answer:

Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7

Step-by-step explanation:

-1.7 + (-6.3)

Correct simplification

-1.7 + (-6.3)

Open parenthesis

= - 1.7 - 6.3

= -8

NOTE:

- * + = -

- * - = +

+ * - = -

+ * + = +

Maureen's simplification

-1.7 + (-6.3)

= 1.7 - 6.3

= -4.6

Maureen ignored the negative(minus) sign in 1.7 thereby turning it into positive 1.7

The circumference of the ellipse approximate. Which equation is the result of solving the formula of the circumference for b?

Serhud [2]

Answer:

$b = \sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}}$

Step-by-step explanation:

Given - The circumference of the ellipse approximated by $C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }$ where 2a and 2b are the lengths of 2 the axes of the ellipse.

To find - Which equation is the result of solving the formula of the circumference for b ?

Solution -

$C = 2\pi \sqrt{\frac{a^{2} + b^{2} }{2} }\\\frac{C}{2\pi } = \sqrt{\frac{a^{2} + b^{2} }{2} }$

Squaring Both sides, we get

$[\frac{C}{2\pi }]^{2} = [\sqrt{\frac{a^{2} + b^{2} }{2} }]^{2} \\\frac{C^{2} }{(2\pi)^{2} } = {\frac{a^{2} + b^{2} }{2} }\\2\frac{C^{2} }{4(\pi)^{2} } = {{a^{2} + b^{2} }$

$\frac{C^{2} }{2(\pi )^{2} } = a^{2} + b^{2} \\\frac{C^{2} }{2(\pi )^{2} } - a^{2} = b^{2} \\\sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}} = b$

∴ we get

$b = \sqrt{\frac{C^{2} }{2(\pi )^{2} } - a^{2}}$
