Answer:
<em>Since one of the angles is 90°, the triangle is right.</em>
Step-by-step explanation:
<u>Angles in a Triangle</u>
The sum of angles in a triangle is 180°. We are given the angles are x, 5x, and 6x, thus:
x + 5x + 6x = 180
Simplifying:
12x = 180
Dividing by 12:
x = 180/12 = 15
x = 15°
5x = 75°
6x = 90°
Since one of the angles is 90°, the triangle is right.
Answer:
to graph it. make a horizontal line for the x axis and a vertical line for the y axis and place your coordinate points were the are supposed to be and label them.
Step-by-step explanation:
- Make the y and x axis.
- label the coordinate points.
- Example:
The coordinate points(3,7) means that 3 would be on the horizontal line and 7 would be on the vertical line meaning the coordinate point(3,7) would be located were the two numbers meet.
Answer: y = -2/3(x-3)^2 + 0 or y = -2/3(x-3)^2
Step-by-step explanation:
vertex form is y=a(x-h)^2 + k
here we can see the vertex is (3,0) which is (x,y). Or (h,k) in this case.
so to plug that into vertex form, we now have y=a(x-3)^2 + 0. or just y=a(x-3)^2.
now we need to find "a" which is the leading coefficient. to do that we can plug in the (6,-6) for the x and y parts of the above equation. so we'd have
-6=a(6-3)^2. which goes to -6=a(2)^2 which is -6=4a. divide each side by 4 to get a = -2/3. plug this in for a
the final equation would be y = -2/3(x-3)^2 + 0 or y = -2/3(x-3)^2
Answer:
K=13,5
y=13,5x, x=numbers of hours
Step-by-step explanation:
To find the proporcionality constant, divide the number of milles traveled in given time.
K=54/4=67,5/5=81/6=13.5 and the equation that describes the relationship is y=13,5x
