Answer:

Option 3: linear, slope = 10, y-intercept = 25

Step-by-step explanation:

Slope = (75-35)/(5-1) = 40/4 = 10

p = 10n + c

35 = 10 + c

c = 25

p = 10n + 25

1.A 2000 W toaster operates on a household circuit of 200 V. What is the resistance of the wire the make up the heating element

MakcuM [25]

P - power measured in watts
E - voltage measured in volts
I - current measured in amperes
R - resistance measured in ohms

$E=IR
\\P=IE$

1. P = 2000 W, E = 200 V, R = ?

$P=IE
\\2000=I200 
\\I=10
\\E=IR
\\200=10R
\\R=20$

2. P = 0.35 W, E = 150 V, R = ?

$P=IE
\\0.35=I150
\\I= \frac{0.35}{150}
\\ E=IR
\\150=\frac{0.35}{150}R
\\R= \frac{150^2}{0.35}
\\R= 64285.71$

The diagonals of a square are 4 meters long. the side of this square is equal to the diagonal of a second square. find the side

Svetllana [295]

Assume s is the side of the first square.
Let's find out the value of s:
4^2 = 2 × s^2 => s = 2.83 meters

Assume S is the side of the second square. Therefore 2.83^2 = 2 × S^2 => S = 2 meters.

The side of the second square is 2 meters
