4 0

Answer:

-90=x(x-18)

-90=x^{2}-18x

0=x^{2}-18x+90

x=9+3i   or   9-3i

Step-by-step explanation:

you need to use quadratic formula and you will find square root a negative ( -9 ), which is an imaginary no.

square root (-9) = 3i

A jet plane has a takeoff speed of vto = 75 m/s and can move along the runway at an average acceleration of 1.3 m/s2. If the len
pishuonlain [190]
Initial velocity of the plane is Vo = 0.
acceleration a = 1.3 m/s2
total distance = 2.5 km = 2500m

time taken to reach 2.5 km with 1.3m/s^2 acceleration = t
S = Vo t + 0.5 a t^2
2500 = 0 + (0.5*1.3* t^2)
t^2 = 3846.15
t = 62 s

the maximum velocity plan can reach within 62 s is Vt
Vt = Vo + a t
Vt = 0 + (1.3*62)
Vt = 80.6 m/s

Since 80.6 m/s is greater than 75 m/s, plane can use this runway to takeoff with required speed.

What is the equation of the circle whose center and radius are given.
muminat
Hello!

The equation for a circle is

(x - h)^{2}  + ( y - k)^{2} =  r^{2}

(h,k) is the center
r is the radius

Put in the values you know

(x - 7)^{2} + ( y + 3)^{2} = 7^{2}

Simplify

(x - 7)^{2} + ( y + 3)^{2} = 49

The equation is (x - 7)^{2} + ( y + 3)^{2} = 49

Hope this helps!
