Answer:
No, a quadrilateral with the given vertices is not an isosceles trapezoid.
Step-by-step explanation:
We are given that
A(3,3), B(5,3), C(8,1), D(1,1)
Slope formula:
Slope of AB=
Slope of BC=
Slope of CD=
Slope of AD=
Slope of AB=Slope of CD
When slopes of two lines are equal then the lines are parallel.
Therefore, AB is parallel to CD.
When one pair of quadrilateral is parallel then the quadrilateral is trapezoid.
ABCD is a trapezoid.
Distance formula:
Using the formula
Length of BC=
Length of BC= units
Length of AD=
Length of AD=
Length of AD is not equal to length of BC.
Hence, trapezoid is not an isosceles trapezoid.
Answer:
d) 35ft
e) 6 seconds
f) 250°
Step-by-step explanation:
If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.
36 secs = 360°
⇒ 1 sec = 360/36 = 10°
d) After 9 seconds, it has turned:
9 x 10 = 90°
Therefore, it will be 15 + 20 = 35ft from the wall
e) 60° = 6 seconds
f) 25 seconds = 25 x 10 = 250°
It would be 33.5, because 1/2 as a decimal is .5
Answer:
Yes.
Step-by-step explanation:
7(5) + (-3) = 32
7(5) + -3 = 32
Both of the equations have the same answer so it's correct.
Answer:
False
Step-by-step explanation:
If it is a right triangle, the Pythagorean theorem will apply
a^2 + b^2 = c^2
4^2 + 5.05^2 = 6.6^2
16 +25.5025 =43.56
41.5025=43.56
This is not true so it is not a right triangle
Round to the nearest integer
4^2 + 5^2 = 7^2
16+25 = 49
41 =49
This is not true
