Answer:
I would say use photomath if you cant find your answer.
Step-by-step explanation:
The equation of a circle centred at point (m,n) and radius r is given by
<span>(x-m)² + (y-n)² = r²
</span>-------------------------------------------------------------
Centre = (4,3)
radius = 5
Equation:
(x - 4)² + (y - 3)² = 5²
⇒ x² - 8x + 16 + y² - 6y + 9 = 25
⇒ x² + y² - 8x - 6y + 25 = 25
⇒ x² + y² - 8x - 6y = 0
The equation of the circle is x² + y² - 8x - 6y = 0
Hope it helps!
Answer:
i honestly thin it might be 8 or4
Step-by-step explanation:
we are given the expression (4e) ^x and is asked to derive the expression. we distribute first the equations resulting to 4^x e^x = y. using the rule of products,
y = 4^x e^xy' = 4^x ln 4 e^x + 4^x e^x
The final answer is y' = 4^x ln 4 e^x + 4^x e^x
(B) 4 hr is the correct answer.
<h3><u>Explanation</u> :</h3>
★ Speed of body is defined as the ratio of distance travelled to the time taken
Given that,
distance = 56 miles
speed = 14 miles per hour
<u>By</u><u> </u><u>subs</u><u>tituting</u><u> </u><u>the</u><u> </u><u>values</u><u>,</u><u> </u><u>we</u><u> </u><u>get</u>
⭆ time = distance/speed
⭆ time = 56/14
⭆ <u>time = 4 hr</u>
