The expression that can be used to approximate the expression below islog_a x = \frac{log_{b}a}{log_{b}x}

  • Given the logarithmic function expressed as log_a x, we need the log expression that is equivalent to the given expression.

  • To do this, we will write the logarithm as a quotient to the same base. Using the base of 10, the expression can be written as;

log_a x = \frac{log_{10}a}{log_{10}x}

This is similar to the option c where the base of "b" was used as log_a x = \frac{log_{b}a}{log_{b}x}

The distance around the wheel of a truck is 9.42 feet .what's the diameter of the wheel
kap26 [50]
To solve this problem, you must follow the proccedure that is shown below:

 1. You need to apply the formula for calculate the perimeter of a circle, which is:

P=2πr

 P is the perimeter of the circle (P=9.42 feet).
 r is the radius of the circle.

 2. Now, you must clear the radius "r" from P=2πr, as below:

 P=2πr
 r=P/2π

 3. When you substitute the values, you obtain:

 r=P/2π
 r=9.42 feet/2π
 r=1.49 feet

 4. Now, you can calculate the diameter (D):

 D=2r
 D=2(1.49 feet)
 D=2.98 feet

A hot air balloon hovers above its launch site at an altitude of 100 meters. The pilot of the balloon sights a parking lot at a
IgorLugansk [536]

Answer:

The horizontal distance between the parking lot and the launch site is 470 meters

Step-by-step explanation:

Let

x----->  the horizontal distance between the parking lot and the launch site

we know that

The tangent of angle of 12 degrees is equal to divide the altitude of 100 meters by the horizontal distance

so

tan(12°)=100/x

Solve for x

x=100/tan(12°)=470 meters

Find the common ratio for the geometric sequence for which a1=3 and a5=48
Rama09 [41]

The ratio is common, so you could write:

a1 * r^4 = a^5 (you do r^4 because there are 4 times you need to multiply by the ratio to get from a1 to a5)

Plug in the values:

3 * r^4 = 48

Divide by 3:

r^4 = 16

Take the fourth root of both sides:

r = 2

The common ratio is 2.
