Answer:
Step-by-step explanation:
we are given a function
we would like to simplify it for h(-1)
in order to do so
substitute the value of x
by order of PEMDAS
simplify square:
simplify multiplication:
simplify addition:
simplify subtraction:
reduce fraction:
Let the ladder length be L, then
sin 70 = 20/L, L = 20/sin70 = 21.3 feet
the length of ladder is 21.3 feet
I might be wrong but, I would say about 32.6 miles a day. This could be wrong.
False... a ratio equivalent to 2:5 is 4:10
2/5 × 2/2 = 4/10
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!
