"8 cm I Circumference cm" can someone explain how to do this? plz?
Answers
Answer:
The area of a circle is [tex]\pi r^{2}[/tex] which is given in the question. (r is radius)
The radius is the length from the centre of the circle to the border of the circle (8cm in this case)
Area of circle:
[tex]\pi r^{2} =\pi *8^{2} =64\pi =201.06cm^2[/tex] (2 decimal places)
Circumference of circle:
[tex]\pi d[/tex] (d is diameter)
The diameter is twice the radius and it is the length of a point on the circle to the opposite point of it.
[tex]\pi d=\pi *2*8=16\pi =50.27cm[/tex] (2 decimal places)
∠1 and ∠2 form a linear pair. If m∠1 = 5x + 9 and m∠2 = 3x + 11, find the measures of both angles.
Answers
Answer:
∠1 =109
∠2= 71
Step-by-step explanation:
if they are a linear pair that means they must both (when added together) equal 180 degrees, so this means we can add them and set them equal to 180!
8x+20=180
8x=160
x=20
then we just input them!
m∠1 = 5(20) + 9 = 109
m∠2 = 3(20) + 11 = 71

2x+3y=7 solve for y.
Answers
Answer:
[tex]y=\frac{7}{3}-\frac{2}{3}x[/tex]
Step-by-step explanation:
To solve for y, we will have to get y by itself on one side of the equation, with all of the other variables and values on the other side.
2x + 3y = 7
Subtract 2x to both sides of the equation.
3y = 7 - 2x
Divide both sides by 3.
[tex]y=\frac{7}{3}-\frac{2}{3}x[/tex]
And now we have solved for y.

Given
y=x²+4x+3
find the vertex,
focus and
directrix
Answers
Answer:
Step-by-step explanation:
The given y=x²+4x+3 should be re-written in "vertex form," which is
y = a(x - h) + k, where (h, k) is the vertex.
Here y=x²+4x+3 = y=x²+4x + 4 - 4 +3 (completing the square), or
y = x^2 + 4x + 4 - 1. which condenses to y = (x + 2)^2 - 1
Thus, h = -2 and k = 1, and so the vertex is at (h, k), or (-2, 1). This parabola opens up. The axis of symmetry is the vertical line x = -2.
An alternative equation for a vertical parabola that opens up is:
y - k = 4p(x - h)^2. Rewriting y = (x + 2)^2 - 1 to fit this form leads to:
y + 1 = 4p(x + 2)^2. We must find the value of p that makes this equation true at any (x, y) on the graph. Suppose we arbitrarily choose x = 1. Then, according to y=x²+4x+3, y = 1^2 + 4(1) + 3, or y = 8 when x = 1.
Then y - k = 4p(x - h)^2 becomes 8 - 1 = 4p(1 + 2)^2, or
7 = 4p(9), or p = 7/36
The focus is thus 7/36 units above the vertex: (-2 + 7/36), and the directrix is the horizontal line which is 7/36 units below the vertex: y = -2 - 7/36.
Vertex: (-2, 1)
Focus: (-2, 2 7/36)
Directrix: y = -2 7/36

Answer: [tex]|h-1.7| \le 0.5[/tex]
==========================================================
Explanation:
The endpoints of this compound inequality are 1.2 and 2.2
Add up the endpoints to get 1.2+2.2 = 3.4
Divide that result in half getting 3.4/2 = 1.7
The midpoint between 1.2 and 2.2 is 1.7
The distance from 1.7 to 1.2 is 0.5 units after we subtract the values (1.7-1.2 = 0.5). Also, from 1.7 to 2.2 is 0.5 units as well (2.2 - 1.7 = 0.5)
The compound inequality [tex]1.7 \le h \le 2.2[/tex] converts to the absolute value inequality [tex]|h-1.7| \le 0.5[/tex]
The portion h-1.7 represents the distance h is from 1.7; we want this distance to be 0.5 or smaller. The use of absolute value is to ensure the result h-1.7 is never negative.
