Answer:
d- m<1 = 58
Step-by-step explanation:
To find this answer we have to do multiple steps.
So we know that vertical angles are congruent by the definition of vertical angles, look at the picture
So, we also know that a triangle =180 degrees
therefore we can add 32 and 90 to find the 3rd angle measure
32+90=122, then 180(because that's the total of the triangle)-122=58
So, m<1=58 degrees

Is 9/10, 1 1/5, 1 1/2 a right triangle?
Answers
Answer:
using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2
a²+b²=c²
(9/10)²+(11/5)²=(11/2)²
81/100+121/25=121/4
lcm of 25 and 100 =100
(81+484)/100=121/4
565/100=121/4
113/20=121/4
since they are not equal therefore it's not a right angle triangle

Step-by-step explanation:
To find the distance between two coordinates, use the formula [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex].
y2 = 4, y1 = 9, x2 = -1, x1 = 2
Insert the values into the equation:

if a parabola is horizontally translated 15 units left, stretch by a factor of 20, vertically translated down 30 units and reflected in the x axis determine the equation of the parabola in vertex form
Answers
Answer:
y' = a(x'- ((h-15)/20))² + -(k-30)
Step-by-step explanation:
Vertex: (h,k)
horizontally translated 15 units left: (h-15 , k)
stretch by a factor of 20: ((h-15)/20 , k)
vertically translated down 30 units: ((h-15)/20 , k-30)
reflected in the x axis: ((h-15)/20 , -(k-30))
Vertex' (h' , k'): ((h-15)/20 , -(k-30))
Equation: y' = a(x'-h')² + k'
y' = a(x'- ((h-15)/20))² + -(k-30)

Find the approximate radius of a circle with a circumference of 198 centimeters. Use 3.14
for it Round to the nearest hundredth.
A. 63.06
B. 31.53
C. 621.72
D. 310.86
Answers
The radius of the circle is around 31.65 cm. Choice B
The formula C = 2πr , where C is the circle's circumference and r is its radius, yields the circumference of a circle. In this illustration, the circle's circumference is given as 198 cm
C = 2πr
The formula to calculate the radius can be revised as follows:
r = C / (2π)
r = 198 / (2 * 3.14)
To perform the calculation, divide the numbers:
r ≈ 198 / 6.28
r ≈ 31.65
The circle's estimated radius is 31.65 centimetres as a result.
So, rounded to the closest hundredth, the estimated radius of the circle with a circumference of 198 centimetres is 31.65 centimetres.
The closest option to 31.65 in the list of possible answers is B. 31.53. It's crucial to keep in mind that choosing 3.14 as an approximation for involves some mistake and that the precise radius number might change slightly.
When rounded to the next hundredth, the radius is 31.65. This result can be compared to the other solutions to show that:
B. 31.53.
