John used 1 3/4 kg of salt to melt on his sidewalk. He then used another 3 4/5 kg on the driveway. If he originally bought 10 kg

Natali [406]

Answer:

he have left 4.45 kg

Step-by-step explanation:

The computation of he have left is as follows:

= Total salt purchase - salt used on his sidewalk - sales used on the driveway

$= 10 - 1 \frac{3}{4} - 3 \frac{4}{5}\\\\= 10 - \frac{7}{4} - \frac{19}{5}\\\\= \frac{200 - 35 -76 }{20} \\\\= \frac{89}{20}$

= 4.45 kg

Hence, he have left 4.45 kg

(Q7) Determine the graph of the polar equation r = 12/6+4 cos theta.

masya89 [10]

ANSWER

b.

EXPLANATION

The given polar equation is,

$r = \frac{12}{6 + 4 \cos( \theta) }$

Cross multiply to get,

$r(6 + 4 \cos( \theta) ) = 12$

$6r + 4r\cos( \theta) ) = 12$

Substitute,

$r\cos( \theta) = x$

and

$r = \sqrt{ {x}^{2} + {y}^{2} }$

$6 \sqrt{ {x}^{2} + {y}^{2} } + 4x = 12$

$3\sqrt{ {x}^{2} + {y}^{2} } + 2x = 6$

$3\sqrt{ {x}^{2} + {y}^{2} } = 4 - 2x$

$9({x}^{2} + {y}^{2}) =( 4 - 2x ) ^{2}$

$9{x}^{2} + 9 {y}^{2} =16 - 16x + 4x ^{2}$

$5{x}^{2} + 9 {y}^{2} + 16x = 16$

This is an ellipse whose center is shifted to the left with orientation on the x-axis

The correct choice is B.
