Using a^2 + b^2 = c^2 it means that
42^2 + 56^2 = c^2
therefore c^2= 4900
so c=70mm

Answer:

70 mm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

c² = 42² + 56² = 1764 + 3136 = 4900 ( take the square root of both sides )

c = $\sqrt{4900}$ = 70

Find the lateral area of the square pyramid.<br> please help ill mark as brainlest!

kozerog [31]

You have a base that is 8x8 and the slant height of the triangle is 22.

This is the formula, L=1/2Ph

H = 22 Meters

1. P=2L+2W -> 2(8)+2(8) = 32 meters

2. L= 1/2(32)(22) = 352 meters squared :)

X^2-4x+3=0 solutions <br>larger and smaller solutions

andrew11 [14]

Answer:

x = 3 or x = 1

Step-by-step explanation:

Solve for x over the real numbers:

x^2 - 4 x + 3 = 0

Subtract 3 from both sides:

x^2 - 4 x = -3

Add 4 to both sides:

x^2 - 4 x + 4 = 1

Write the left hand side as a square:

(x - 2)^2 = 1

Take the square root of both sides:

x - 2 = 1 or x - 2 = -1

Add 2 to both sides:

x = 3 or x - 2 = -1

Add 2 to both sides:

Answer: x = 3 or x = 1

If a tank holds 4500 gallons of water, which drains from the bottom of the tank in 50 minutes, then Toricelli's Law gives the vo

disa [49]

Answer:

The response to this question can be defined as follows:

Step-by-step explanation:

$v =4500 (1-\frac{t}{50})^2\\\\\to \frac{dV}{dt}= 9000 (1- \frac{t}{50})(\frac{1}{50})\\\\$

$= 180 (\frac{50-t}{50})\\\\= 3.6(50-t)\\\\$

For point a:

$t=5\\\\V'=3.6\times 45 = 162\\\\ans= - 162\ \frac{gal}{min}\\\\$

For point b:

$t=10\\\\V'=3.6\times 40 = 144\\\\ans= - 144 \ \frac{gal}{min}\\\\$

For point c:

$t=20\\\\V'=3.6\times 30 = 108\\\\ans= - 108 \ \frac{gal}{min}\\\\$

For point d:

$t=50\\\\V'=3.6\times 0 = 0\\\\ans= 0 \ \frac{gal}{min}\\\\$
