[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse<u>
</u>
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
Leg <em>a</em> = <em>a</em>
Leg <em>b</em> = 12
Hypotenuse <em>c</em> = 20
<u>Step 2: Solve for </u><em><u>a</u></em>
- Substitute in variables [Pythagorean Theorem]: a² + 12² = 20²
- Evaluate exponents: a² + 144 = 400
- [Subtraction Property of Equality] Isolate <em>a</em> term: a² = 256
- [Equality Property] Square root both sides: a = 16

Answer:
A signal from the transmitter will be picked up through out the 57.38 mile drive
Step-by-step explanation:
The radius of the transmitter = 63 miles
Therefore, since both the location 38 miles north and the location 43 miles east of the transmitter are within the the radius, the transmission of the transmitter will be received through out the straight line journey
The length of the travel path is given by;
Distance from 38 miles north of the transmitter to distance of 43 miles east of transmitter =
.
Answer:
y = 3x - 4
Step-by-step explanation:
Slope-intercept is defined <em>y = mx + b</em>
Where m = slope (change in y-coordinate/ change in x-coordinate)
and b = y-intercept (where the graph crosses the y-axis)
For every 1 unit the line moves horizontally... it travels 3 units vertically. Therefore the slope (m) equals 3/1 or 3
The line crosses the y-axis at -4. Therefore... the y-intercept (b) is -4
I hope this helps!
