Answer:

yr answer is G. 21

log 2 (24) - log 2 (3) = log 5 (x)

log 2 (24 / 3) = log 5 (x)

log 2 (8) = log 5 (x)

log 2 (2^3) = log 5 (x)

3 × log 2 (2) = log 5 (x)

3 × 1 = log 5 (x)

3 = log 5 (x)

x = 5^3

x = 125

Answer:  #2; 25.13274,  #3; 167.55161

Step-by-step explanation:

The dimensions of the rectangle are (2y – 7) units by (2y + 7) units

The formula for calculating the area of a rectangle is expressed as

Area = length * width

Given the following parameter

Area = .4y² - 49

Factorize the area

Area = (2y)² - 7²

Using the difference of two square

Area = (2y - 7)(2 y + 7)

Hence the dimensions of the rectangle are (2y – 7) units by (2y + 7) units

Answer:

y = 2x

Step-by-step explanation:

1. attendee = x

2. cost = y

3. for each attendee [x], you have $2 of cost, so for each 1 x, you have 2 as result

4. Thus, y = 2x

Answer:

-3-2i

Step-by-step explanation:

u+V= 1+3i+(-4-5i)=1+3i-4-5i= -3-2i

The First two coefficients are positive because they are on the positive side of the y-axis.

The Last two are on the negative side of the y-axis. B is the closest to zero as the wider the graph is, the lower the coefficient is.

The coefficient with the greatest value would be D

Answer:

Net commission= $1,275

Step-by-step explanation:

Giving the following information:

Sales= $8,500

Sales commission rate= 15% = 0.15

To calculate the net commission, we need to use the following formula:

Net commission= sales * Sales commission rate

Net commission= 8,500 * 0.15

Net commission= $1,275

Answer:

Answer:

width is 2√33 cm

Step-by-step explanation:

you will make a right triangle with hypothenuse 14 , one side 8 and the other side x is the width.

use Pythagorean Th.

14² = 8² + x²

x² = 14² -8²

x² = 132

x = √132 = 2√33

Answer:

403909578

Step-by-step explanation:

Answer:

The length of diagonal BD is 11·(1 + √3)

The length of diagonal AC = 22

Step-by-step explanation:

The given data are;

Quadrilateral ABCD = A kite

The length of segment AD = 22

The measure of ∠DAE = 60°

The measure of ∠BCEE = 45°

Whereby, triangle ΔADE = A right triangle, and DE is the perpendicular bisector of AC, by trigonometric ratio, we have;

AE = EC

DE = 22 × sin(60°) = 11·√3

AE = 22 × cos(60°) = 11

∴ AE = EC = 11

BE = EC × tan(∠BCE) = 11 × tan(45°) = 11

The length of the diagonal BD = BE + DE (By segment addition property)

∴ BD = 11 + 11·√3 = 11·(1 + √3)

The length of diagonal BD = 11·(1 + √3)

The length of diagonal AC = AE  + EC

∴ AC + 11 + 11 = 22

The length of diagonal AC = 22.
