What is the value of c? O 4 units O 5 units O 6 units O 7 units

Aleksandr [31]

The value of c is 5 units.

Step-by-step explanation:

Given,

WY = a = 4

ZY = b = 3

As WYZ is forming a right angle triangle, therefore, we can use pythagorean theorem to find the value of c

$a^2+b^2=c^2\\(4)^2+(3)^2=c^2\\16+9=c^2\\c^2=25$

Taking square root on both sides

$\sqrt{c^2}=\sqrt{25}\\c=5$

The value of c is 5 units.

Sam has $400 in his bank account and plans to save $25 per week. Zoe has $250 in her bank account and plans to save $75 per week

elena-14-01-66 [18.8K]

Say x is the number of weeks until their money is equal. Then, we can set up an equation.

400 + 25x = 250 + 75x

Subtract 250 from both sides

150 + 25x = 75x

Subtract 25x from both sides

150 = 50x

Divide by 50 on both sides

3 = x

That means the answer is 3 weeks.

Answer: Choice A) $3 \sqrt{26}$

==================================================

Work Shown:

$\text{The two points are } (x_1,y_1) = (6,7) \text{ and } (x_2,y_2) = (3,-8)\\\\d = \text{Distance between } (x_1,y_1) \text{ and } (x_2,y_2)\\\\d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2} = \text{Distance Formula}\\\\d = \sqrt{(6-3)^2+(7-(-8))^2}\\\\d = \sqrt{(6-3)^2+(7+8)^2}\\\\$

$d = \sqrt{(3)^2+(15)^2}\\\\d = \sqrt{9+225}\\\\d = \sqrt{234}\\\\d = \sqrt{9*26}\\\\d = \sqrt{9}*\sqrt{26}\\\\d = 3\sqrt{26}\\\\$

When going from 234 to 9*26, the idea here is to factor where one factor is the largest perfect square possible. That way we can use the rule $\sqrt{x*y} = \sqrt{x}*\sqrt{y}$ to break up the root and simplify.
