First one:
The circumference of the whole circle is (2π x the radius), 
and 60° is (60/360) = 1/6 of the whole circumference.

Second one:
The area of the whole circle is (π x the radius²), and
the 40° sector is (40/360) = 1/9 of the whole area.

I hope this is enough help.

The height of a triangle is 4 m less than its base. The area of the triangle is 48 m².What is the length of the base?
yaroslaw [1]

Triangle Area = .5 * base * height

48 = .5 * (x +4) * x

48 = (.5x + 2) * x

48 = .5x^2 + 2x

.5x^2 + 2x -48 = 0

x = 8

base = 12

If g x 3x 5 then g 1 x
Ray Of Light [21]
G(x) = 3x + 5
y = 3x + 5
3x = y - 5
x = (y - 5)/3

Therefore, g^-1(x) = (x - 5)/3

Find the quotient of these complex numbers (4-6i)/(2-5i)
Yakvenalex [24]

Answer:

\frac{38}{29} + \frac{8}{29}i

Step-by-step explanation:

We have to find the quotient of the division of complex numbers \frac{(4 - 6i)}{(2 - 5i)}.

Now, we have to get the expression in simplified form.

\frac{(4 - 6i)}{(2 - 5i)}

= \frac{(4 - 6i)(2 + 5i)}{(2 - 5i)(2 + 5i)} {Rationalizing the denominator}

= \frac{4(2 + 5i) - 6i(2 + 5i)}{2^{2} - (5i)^{2}}

= \frac{8 + 20i - 12i - 30(i)^{2}}{4 + 25}

{Since, i = √(- 1) i.e. square root of negative one, hence, i² = - 1}

= \frac{8 + 30 + 8i}{29}

= \frac{38}{29} + \frac{8}{29}i (Answer)

-7(5-3x)=-35 what is the x in the problem
Irina-Kira [14]

Answer:

x = 0

Step-by-step explanation:

-7(5-3x)=-35

Divide by -7

-7/-7(5-3x)=-35/-7

5 -3x = 5

Subtract 5 from each side

5-3x-5 = 5-5

-3x=0

Divide by -3

x=0
