Please give a simple summary of log functions.

3 0

Logarithmic functions are the inverses of exponential functions. The inverse of the exponential funtion y = ax is x = ay. The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay. A logarithm is really nothing more than an exponent.

Trava [24]

The value of ∠EBD is 66°

<h3>Vertically opposite angles</h3>

Vertical angles are a pair of opposite angles formed by intersecting lines. Vertical angles are equal. Therefore,

∠EBA≅∠CBF

Therefore,

∠EBA = 40 - x

∠EBA + ∠EBD = 90°(complementary angles)

Therefore,

40 - x + 6x - 30 = 90

5x = 90 + 30 - 40

5x = 80

x = 80 / 5

x = 16

Therefore,

∠EBD = 6(16) - 30 = 66°

The horsepowers of 12 sports cars are: 397, 320, 300, 310, 355, 362, 342, 375, 378, 402, 375, and 368.

nydimaria [60]

Answer is C. 365

Step One: (Put the numbers in order from least to greatest)
300, 310, 320, 342, 355, 362, 368, 375, 375, 378, 397, 402,

Step Two: (FInd the number(s) that are directly in the middle).
- Normally it's one number, but since this is an even number (12). There's two in the middle. 362, 368.

Step Three: (Add them then divide | only do this when there's two numbers in the middle)
362 + 368 = 730.
730 divided by 2 = 365

Answer:

Cylinder

(with radius of 4 units and height of 4 units)

Step-by-step explanation:

First, determine the shape of the 2D figure.

Point B is above point A, and point C is above point D.

Point A and B, and points C and D are on the same horizontal line.

Points A and B both have an x-value of zero.

Points C and D both have an x-value of 4.

Therefore, the width of the shape is 4 units

Points A and D have an y-value of zero.

Points B and C have an y-values of 4.

Therefore, the height of the shape is 4 units.

Therefore, the shape of the 2d figure is a square with side length of 4 unit. (See first attached image).

If the square is rotated above the y-axis, it creates a cylinder with a radius of 4 units and a height of 4 units. (See second attached image).

The ratio of the measures of the sides of a

ANTONII [103]

Answer:

The length of the sides are 8 , 32 , 36

Step-by-step explanation:

Ratio of sides = 2 : 8 : 9

The sides are 2x , 8x , 9x

Perimeter of triangle = 76 inches

2x+ 8x + 9x = 76

19x = 76

x = 76/19

x = 4

2x = 2*4 = 8

8x = 8 * 4 = 32

9x = 9 * 4 = 36
