Answer:
The axis of Symmetry divides a line into two equal halves.
Step-by-step explanation
An easy relation to get this value without plotting a graph is x = –b/2a
Where
a = coefficient of x²
b = coefficient of x
From the Question, We need a symmetry of value –½
The only Option that'll give this value is OPTION D
2x – y = 5 – 2x²
Since its a line, Don't forget to make "y" subject before doing any operation.
y = 2x² + 2x – 5
a = 2
b= 2
x = –(2)/2(2)
= –2/4
= –½
A triangle has sides of lengths 16,14 and 50 .is the triangle right angle triangle?
Answer:
no
Step-by-step explanation:
using the converse of Pythagoras' identity
If the square on the longest side is equal to the sum of the squares of the other 2 sides, then the triangle is right.
longest side = 50 ⇒ 50² = 2500
16² + 14² = 256 + 196 = 452
since 452 ≠ 2500 then the triangle is not right
A triangle has sides of lengths 16,14 and 50. Is the triangle right angle triangle?
❒ Explanation -:We will solve this question using Pythagoras theorem.
We know,
[tex] \small \boxed{\rm{ c² = a² + b²}}[/tex]
[tex] \small\rm{Where,} [/tex] [tex]\small\sf{ c > a \: and \: c > b}[/tex]
[tex] \small\sf{ 50² = 16² + 14²}[/tex]
[tex]2500 = 256+ 196[/tex]
[tex]2500≠452[/tex]
[tex] \small\bf{ c² ≠ a² + b²}[/tex]
Hence, the triangle is not a right-angled triangle.

What is the point-slope form of a line with slope -5 that contains the point
a
(2,-1)?
The point-slope form the line which has the value of slope -5 and contains a point as A(2,-1) is (y+1)=-5(x-2).
What is point slope form?The point slope form of a line is the expression of line which has a specified slope and passes through a point.
The point slope form is givne as,
(y-y₁)=m(x-x₁)
Here, m is the slope of the line, x₁ is the x coordinate of the point by which line passes and y₁ is the y coordinate of the same point.
The slope of a line is -5. This line contains the point A (2,-1). Thus, the point slope form is,
(y-y₁)=m(x-x₁)
(y-(-1))=-5(x-2)
(y+1)=-5(x-2)
Thus, the point-slope form the line which has the value of slope -5 and contains a point as A(2,-1) is (y+1)=-5(x-2).

The values of x in f(x) = 3|x - 2| + 6 when f(x) = 18 are 6 and -2
How to determine the value of x?The function is given as:
f(x) = 3|x - 2| + 6
The value of f(x) is
f(x) = 18
So, we have:
3|x - 2| + 6 = 18
Subtract 6 from both sides
3|x - 2| = 12
Divide both sides by 3
|x - 2| = 4
Remove the absolute bracket
x - 2 = 4 or x - 2 = -4
Add 2 to both sides
x = 6 or x = -2
Hence, the values of x are 6 and -2

One winter day, the temperature at noon was -9f The temperature then rose by 1/2 degree each hour for 3 hours before dropping by 2 1/4 degrees each hour for 2 hours. What was the temperature, in degrees Fahrenheit, at 5 PM?
Answer:
The temperature at 5 PM was - 12°FStep-by-step explanation:
One winter day, the temperature at noon was -9°F.
The temperature then rose by 1/2 degree each hour for 3 hours:
1/2 × 3 = 3/2 = 1 1/2The temperature then dropped by 2 1/4 degrees each hour for 2 hours:
- 2 1/4 × 2 = - 4 2/4 = - 4 1/2Now add up all three values to find the final value:

a lawn sprinkler waters a lawn in a circle as shown
Part A
I'm assuming you want the area of a circle with radius 17 yards.
We'll use the formula below
A = pi*r^2
A = (22/7)*17^2
A = (22*17^2)/7
A = 6358/7
A = 908 2/7
The sprinkler covers an area of about 908 2/7 square yards.
You'll type 908 in the left-most box
Then for the other two boxes, you'll have 2 up top and 7 down below to represent the fraction 2/7
The number 908 2/7 is a mixed number.
=======================================================
Part B
You mentioned that the radius reduces to 11 yards here. We'll use the same formula as above and pi = 22/7 approximately
A = pi*r^2
A = (22/7)*11^2
A = (22*11^2)/7
A = 2662/7
A = 380 2/7
The sprinklers can water an area of about 380 2/7 square yards.
This value is also a mixed number
380 is the value in the left most box (it's the whole part)
The other two boxes are filled out the same exact way as the previous part above.

How many sides does a regular n-gon have if the measure of one interior angle is 165?
The supplement of each interior angle has measure
180° - 165° = 15°
and so
n = 360°/15° = 24
since the exterior angles add up to 360° and are all congruent.
