Answer:

14.6 units

Step-by-step explanation:

AB = $\sqrt{(1-3)^2+(3-5)^2}$

AB = $\sqrt{8}$

BC = $\sqrt{(3-1)^2+(-1-3)^2}=\sqrt{20}$

CD = $\sqrt{(5-3)^2+(3-(-1))} = \sqrt{20}$

DA = $\sqrt{(5-3)^2+(3-5)^2} = \sqrt{8}$

Primeter = $\sqrt{8} + \sqrt{20} + \sqrt{20} +\sqrt{8} = 14.6$

What is the value of the expression below when z =5 and w=5? 9z-3w

zysi [14]

This is just about substitution!! 9(5)-3(5), 3 • 5 = 15
9 • 5 = 45
so Now you have, 45 - 15 = 30

Answer:

Step-by-step explanation:

Thinking process:

$\int\limits^a_b {cF} \, .dr$

= $\int\limits^a_b {x} \, dx \int\limits^a_b {x} \, dx curlFdS$ by Stoke's Theorem

= $\int\limits^a_b {} \, \int\limits^a_b {} \, < 12y, -12x, 0 > .< z_x,-z_y, 1 > dA\\= \int\limits^a_b {} \, \int\limits^a_b {} \, < 12y, -12x, 0 > .< 2x, 2y, 1 > dA$ since z = $25-x^{2} -y^{2} \\= 0$
