Equation of circle is x² + y² - 25 = 0

(b).

(-5, 0) » yes

(√7, 1) » no

(-3, √21) » no

(0, 7) » no

Step-by-step explanation:

(a).

If centred at origin, centre is (0, 0)

General equation of circle:

${ \boxed{ \bf{ {x}^{2} + {y}^{2} + 2gx + 2fy + c = 0}}}$

but g and f are 0:

${x}^{2} + {y}^{2} + c = 0 \\ but : \\ c = {g}^{2} + {f}^{2} - {r}^{2} \\ c = { - 25}$

Angle e measures 126LaTeX: ^\circ∘. What is the measure of LaTeX: \angle∠h?

SVEN [57.7K]

Answer:

$m\angle h=126^o$

Step-by-step explanation:

we know hat

Vertical Angles are the angles opposite each other when two lines cross. They are always congruent.

In this problem

$m\angle h=m\angle e$ ----> by vertical angles

we have

$m\angle e=126^o$ ---> given problem

therefore

$m\angle h=126^o$

Quantity of mushroom bought = 4.25pounds

Cost of each mushroom = $2.99

Unknown:

Best estimate for the cost of the mushroom = ?

Solution:

The cost of the mushroom is:

Total cost = quantity of mushroom bought x cost of each mushroom

Total cost = 4.25 x 2.99

You can round 4.25 to 4 and 2.99 to 3

Or 4 x 3 = $12
