Circumference of the circle as 15 pi inches find the diameter
Answers
The formula for the circumference of the circle is 2πr or πd with r being the radius and d being the diameter. These 2 gives the same result because d=2r
Now because we know that the circumference is 15pi, we just need to reverse to find the diameter.
π*diameter=15*π
We can divide π from both sides.
diameter=15

Answer:
124 degrees since all angles should equal 180 degrees.
Answer:
So if you think about it, 180° is a full angle. So if you take the 180° and subtract the 19° and the 37° you should get your remaining angle. the answer I got for the angle is 124°. To check your work, 124° + 19° + 37° = 180°

c. 6x^2+21x+56
d. 6x^2-41x-56
(w+3)(w-3)
a. w^2+3w-3
b. w^2
c. w^2-9
d. w^2+w
Answers
Answer:
First one is d and second one is c
Step-by-step explanation:
(6x+7)(x-8)
(6x)(x) = 6x^2
(6x)(-8) = -48
(7)(x) = 7x
(7)(-8) = -56
Add all like terms together and you get choice d.
(w+3)(w-3)
(w)(w) = w^2
(w)(-3) = -3w
(3)(w) = 3w
(3)(-3) = -9
Add all like terms together and you get choice c

for the second question the options are: 71034, 71034000, 710.34 and 7013.4
Answers
Answer:
[tex]0.0005[/tex] [tex]= 5 * 10^{-4[/tex]
[tex]7.1034 * 10^3 = 7103.4[/tex]
Step-by-step explanation:
Solving (a):
[tex]0.0005[/tex]
Standard form is represented as:
[tex]a * 10^n[/tex] where [tex]1 \le a \le 10[/tex]
Move the decimal point to 5 and count the number of times the decimal point is moved forward (forward represents negative).
So:
[tex]a = 5[/tex]
[tex]n = -4[/tex]
Hence:
[tex]0.0005[/tex] [tex]= 5 * 10^{-4[/tex]
Solving (b):
[tex]7.1034 * 10^3[/tex]
Express [tex]10^3[/tex] as [tex]1000[/tex]
This gives:
[tex]7.1034 * 10^3 = 7.1034 * 1000[/tex]
[tex]7.1034 * 10^3 = 7103.4[/tex]

What is the slope of the line whose equation is 2x – 4y = 9?
a) 1
2
c) 2
d) 3
solotion
Answers
Answer:
m = 1/2
Step-by-step explanation:
The given equation of line is :
2x – 4y = 9 ..(1)
We need to find the slope of the line. The general equation of a line is given by :
y = mx + c ..(2)
Where
m is the slope of line
Equation (1) can be rearranged as follow :
-4y = 9-2x
4y = -9+2x
or
4y = 2x-9
Divide both sides by 4.
[tex]\dfrac{4y}{4} = \dfrac{2x}{4}-\dfrac{9}{4}\\\\y=\dfrac{1}{2}x+(\dfrac{-9}{4})[/tex] ..(3)
Now comparing equation (2) and (3) we get :
[tex]m=\dfrac{1}{2}[/tex]
So, the slope of the line is 1/2.
