Find the circumference and area of a circle with a radius of 7 m. Use the π key on your calculator and round to the nearest tenth.
Answers
Answer:
The answer is 44.0 mStep-by-step explanation:
The circumference of a circle = 2πr
where
r is the radius of the circle
From the question
r = 7 m
Substitute this value into the above formula and solve
That's
C = 2(7)π
= 14π
= 43.9822971502
We have the final answer as
44.0 m to the nearest tenthHope this helps you
Circumference formula: C = 2πr
C = 2π(7)
C = 14π
C ≈ 43.98
Area formula: A = πr²
A = π(7)²
A = 49π
A ≈ 153.94

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.

The table represents the function f (x) = 5x - 8.
Find f(-4):
f(-4)= 5(-4)-8
f(-4) = -28
Answers
Answer:
a=-18
b=7
c=27
Step-by-step explanation:
Given the function f (x) = 5x - 8 ,for different value of f(x)
f (-2)=-18
f (-2)=7
f (-2)=27
How to solve function?
A) for f (x) = 5x - 8 where f (-2).
⇒ f (-2) = 5x - 8
⇒ f (-2) = 5(-2) - 8
⇒ f (-2) = -10 - 8
⇒ f (-2) =-18
B) for for f (x) = 5x - 8 where f (3).
⇒ f (3) = 5x - 8
⇒ f (3) = 5(3) - 8
⇒ f (3) = 15 - 8
⇒ f (3) =7
C) for f (x) = 5x - 8 where f (7).
⇒ f (7) = 57 - 8
⇒ f (7) = 5(7) - 8
⇒ f (7) = 35- 8
⇒ f (7) =27

Step-by-step explanation:
Due to the Consecutive Interior Angles rule, c + e = 180. So, 20x + 5 + 24x - 1 = 180.
If you solve, you will get x = 4
Work:
20x + 5 + 24x - 1 = 180 [Add like terms]
44x + 4 = 180 [Isolate the variable]
44x = 176 [Solve]

∠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
