Find the value of AB. 13 12 A В AB = [?

Sedaia [141]

Answer:

$AB=24$

Step-by-step explanation:

CD is perpendicular to AB

If any radius or diameter is perpendicular to any chord of a circle, then it bisects that chord.

Mean, AB= BE = 12

So, AB = 2(BE)

2(12)= 24

so your answer will be 24

Evaluate the expression n-f x 8 if n= 84.15 and f=1.8

Gnesinka [82]

84.15-1.8*8
Order of Operations says to add and subtract before you multiply, so simplify the expression to: 82.35*8, which is 658.8

A car advertisement claims that a certain car can accelerate from rest to 70 km/hr in 7 seconds find the car acceleration

iVinArrow [24]

Answer:

acceleration $\approx 2.78\,\,\frac{m}{s^2}$

Step-by-step explanation:

The acceleration is the change in velocity per unit of time.

Therefore to have this rate in appropriate units that can combine, we re-write the change from 0 to 70 km/h in meters per second using:

$70 \frac{km}{h} = \frac{70000}{3600} \frac{m}{s}$

so in this case the acceleration becomes:

$accel=\frac{change\,\,vel}{change\,\,time} =\frac{70000m}{3600\,*7\,s^2} \approx 2.78\,\,\frac{m}{s^2}$

Which of the following is the conjugate of a complex number with 4 as the real part and −3i as the imaginary part?

White raven [17]

Answer:

$4+3i$

Step-by-step explanation:

we know that

To find the conjugate complex of a complex number, simply change the sign of the imaginary part of the complex number

In this problem we have

$4-3i$

the complex conjugate is equal to

$4+3i$
