Answer:
y = 1x - 1
Step-by-step explanation:
y = mx + b
m is slope
slope = change in y / change in x = (3 - 2) / (4 - 3) = 1/1 = 1
m = 1 so equation is now y = 1x + b
To find b, substitute any value from the table. Let's use (3,2)
y = 1x + b
2 = 1(3) + b
2 = 3 + b
-1 = b
So equation is y = 1x - 1
Exponent rule : a^-b = 1 / a^b
52^-5 =
1 / 52^5 =
1 / (52 * 52 * 52 * 52 * 52)
7.65 x 10⁻² Because 10⁻² makes the decimal move two places to the left
Answer:
The perimeter of ΔABC is 43 units
Step-by-step explanation:
An illustrative diagram is shown in the attachment below.
To find the perimeter of the triangle, we will first determine the length of the unknown sides.
First, we can determine /BC/ using the Sine rule
From Sine rule
∴
In the diagram, and
m∠A=60° and m∠C=45°
∴
To find /AC/, will first determine m∠B
m∠A + m∠B + m∠C = 180° (Sum of angles in a triangle)
60° +m∠B + 45° = 180°
m∠B + 105° = 180°
m∠B = 180° - 105°
m∠B = 75°
Also, using the sine rule
From the diagram,
Now,
The perimeter of ΔABC = /AB/ + /BC/ + /AC/
=
= 43.09 units
≅ 43 units
Hence, the perimeter of ΔABC is 43 units.
