Answer:

1) 25 = 5²

2) x = 5²

3) 64 = b³

Step-by-step explanation:

logb(a) = x

a = b^x

log5(25) = 2

25 = 5²

log5(x) = 2

x = 5²

logb(64) = 3

64 = b³

Answer:

1) 5^2=25

2) 5^2=x

3) b^3=64

Step-by-step explanation:

To write logs of the form log_ba=x in their exponential form, you take the base b and put it to the power of x and then set that equal to a: b^x=a.

1. Here, b = 5, a = 25, and x = 2, so: 5^2=25

2. In this problem, b = 5, x = 2, and a = x, so: 5^2=x

3. Finally, here, b = b, a = 64, and x = 3, so: b^3=64

Hope this helps!

A bathtub contains 20 gallons of water. After the drain is opened, there are 14 gallons of water remaining after 30 seconds. Usi
leva [86]

Answer

a decrease of 0.2 gallons per second

Explanation

The drain was open for 30 seconds.

The water that ran out for 30 seconds = 20 - 14

= 6 gallons

Rate of decrease = (change in gallons)/(time taken)

= 6/30

= 0.2

The rate of change in the amount of water remaining in the tub per second will be the same as the one that ran out since the outlet is the same.

So the correct answer from the choices is "a decrease of 0.2 gallons per second".

Angle <QAB is =15° because the opposite angles of an isosceles triangle are equal.

The length of the straight line AB = 80cm

<h3>Calculation of angle of a triangle</h3>

The angle at a point = 360°

Angle AQB= 360 - 210° = 150

But the angle that makes up a triangle= 180°

180-150= 30°

But <QAB = <QBA because triangle AQB is an isosceles triangle.

30/2 = 15°

To calculate the length of the straight line the following is carried out using the sine laws.

a/ sina, = b sinb

a= 8cm, sin a { sin 15)

b= ? , sin B = 150

make b the subject formula;

8/sin15= b/sin 150

b= 8 × sin 150/sin 15

b= 80cm
