A climber starts descending from 533 feet above sea level and keeps going until she reaches 10 feet below sea level.How many feet did she descend?

Answers

It's actually 543 feet because at 523 feet that would mean she is still 10 feet above sea level. So you need to add another 20 feet to get to 10 feet below sea level.

Answer:

Option B

Option C

Step-by-step explanation:

$x^(2) +2x=4$

we need to divide the coefficient of x by half since it is required for completing square, this term is added and subtracted at the same time to keep the equation intact, so we have

$x^(2) +2x+1-1=4$

later we have

$(x+1)^(2) -1=4$

$(x+1)^(2)= 4+1$

$(x+1)^(2) = 5$

$\sqrt{(x+1)^(2)} =√(5)$

we know

$\sqrt[2]{a^(2)} = abs (a)$

$abs(x+1)=√(5)$

we have

$x+1=√(5)$

$x+1= -√(5)$

so we have

$x=√(5)-1$

$x=-√(5)-1$

finally

$x=+- √(5)-1$

The second is obtained by summing the two given equations

f(x)=8x-10

g(x)=3x+5

-----------------

f(x)+g(x)=11x-5

Calculating the Least Common Multiple

9.1 Find the Least Common Multiple

The left denominator is : 50

The right denominator is : 25

Number of times each prime factor

appears in the factorization of:

Prime

Factor Left

Denominator Right

Denominator L.C.M = Max

{Left,Right}

2 1 0 1

5 2 2 2

Product of all

Prime Factors 50 25 50

Least Common Multiple:

Calculating Multipliers :

9.2 Calculate multipliers for the two fractions

Denote the Least Common Multiple by L.C.M

Denote the Left Multiplier by Left_M

Denote the Right Multiplier by Right_M

Denote the Left Deniminator by L_Deno

Denote the Right Multiplier by R_Deno

Left_M = L.C.M / L_Deno = 1

Right_M = L.C.M / R_Deno = 2

Making Equivalent Fractions :

9.3 Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

L. Mult. • L. Num. 837

—————————————————— = ———

L.C.M 50

R. Mult. • R. Num. 279 • 2

—————————————————— = ———————

L.C.M 50

Adding fractions that have a common denominator :

9.4 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

837 - (279 • 2) 279

——————————————— = ———
