Answer:

1 + ln 2 - ln x

Step-by-step explanation:

ln ( 2e /x)

We know that ln ( a/b) = ln ( a) - ln (b)

ln (2e) - ln (x)

We also know that ln ( a*b) = ln a + ln b

ln ( 2) + ln e - ln x

We know that the ln e = 1

ln 2 + 1 - ln x

Changing the order

1 + ln 2 - ln x

Answer:

gradient = -4/3

Step-by-step explanation:

information not complete, but this is the equation of a straight line, and assume you want to know the gradient

3y = 8 - 4x

3y = -4x + 8

dividing both sides by 3

y = -4/3x + 8/3

comparing the equation to equation of a straight line;

y = mx + c

m = -4/3

The corresponding sides of two similar rectangles are 14 ft and 8 ft. The area of the smaller rectangle is 57 ft2. To the neares

Greeley [361]

Assume they are right triangles, find the other side of the smaller triangle
2(57/8) = 14.25 sq/ft: (.5*14.25*8=57).
Find the other side of the larger triangle, using corresponding sides in
similar triangles
*14.25 = 24.9375

Find the area of the larger triangle
.5*14*24.9375 = 174.5625 sq/ft area of the larger triangle.

If the gradient of line A is 4 what is the gradient of the line which is perpendicular to A

zhannawk [14.2K]

Answer:

perpendicular slope = - $\frac{1}{4}$

Step-by-step explanation:

given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$

the given slope m = 4, hence

$m_{perpendicular}$ = - $\frac{1}{4}$

Secant and tangent theorem: Square of measure of tangent is equal to the product of length of whole secant and length of exterior secant segment, i.e.

$\text{ tangent }^2=\text{whole secant}\cdot \text{exterior secant}$ .

The whole secant wuth exterior secant 4 cm is 4+x cm. Tangent is 7 cm. Using previous theorem, you can get that

$7^2=(4+x)\cdot 4$ .

Solve this equation:

$49=16+4x,\\ 4x=49-16,\\ 4x=33,\\ x=8.25\approx 8.3$ cm.

Answer: x=8.3 cm.
