A^2+b^2=1305, a*b=648, a-b=?

luda_lava [24]

a - b is 9

Step-by-step explanation:

Step 1: Given a² + b² = 1305, a × b = 648. Find a - b using the identity for (a - b)²

⇒ (a - b)² = a² + b² - 2ab

⇒ (a - b)² = 1305 - 2 × 648 = 1305 - 1296 = 9

⇒ (a - b) = 9

Use the point-slope formula to write an equation of the line that passes through (6,23) and has a slope of m= 3. Write the answe

RSB [31]

y=3x+5

plug your coordinate points into the equation for slope (left corner or the paper)

multiply by the denominator on both sides of the equation

x-6 cancels out and leaves y-23=3(x-6)

multiply x and -6 by 3

add 23 to both sides to isolate y

hope this helps!

A jeweler is dividing

tatuchka [14]

Question:

A jeweler is dividing 3/8 of a pound of rubies among 4 lots. What part of a pound will each lot weigh? A.1/4 B.1/8 C.1/16 D.3/32

Answer:

Option D

Each lot weight $\frac{3}{32}$ part of pound

Solution:

Given that,

A jeweler is dividing 3/8 of a pound of rubies among 4 lots

To find: part of a pound each lot weigh

From given,

$\frac{3}{8} \text{ of a pound } = 4 lots$

Let "x" be the part of a pound each lot weigh

Therefore,

$\frac{3}{8} \text{ of a pound } = 4 lots\\\\"x" part = 1\ lots$

This forms a proportion and solve by cross multiplying

$\frac{3}{8} \times 1 = 4 \times x\\\\x = \frac{3}{32}$

Thus, each lot weight $\frac{3}{32}$ part of pound
