The center and a point on a circle are given. Find the circumference to the nearest tenth.
center:(2, 2);
point on the circle: (−6, 5)
The circumference is about ?
Answer:
Circumference ~ 53.4
Step-by-step explanation:
Use the distance formula to get the radius of the circle. The radius is about 8.5. Now put 8.5 into the formula 2(pi)r for the Circumference. Rounding to the nearest tenth the answer is 53.4

Fritz is recording the decay of radioactive material. The table displays the
number of weeks and the level of radioactivity he measures each week.
What will be the level of radioactivity in 10 weeks?
Answer:
Every week, the radioactivity decreases by a factor of 5
After 1 week, it goes from 5,000 to 1,000
2 weeks 1,000 / 5 =200
3 weeks 200 / 5 = 40
4 weeks 40 / 5 = 8
5 weeks 8 / 5 = 1.6
6 weeks 1.6 / 5 = 0.064
7 weeks 0.064 / 5 = 0.0128
8 weeks .0128 / 5 = 0.00256
9 weeks 0.00256 / 5 = 0.000512
10 weeks 0.000512 / 5 = 0.0001024

student simplifies (6b + 4r) – (2b + r) and says that the result is 4b + 5r. Explain the error and describe the correct steps to simplify the expression.
Answer & explanation:
The student made an error by adding an r after removing the parentheses instead of subtracting an r.
Correct Steps:
(6b + 4r) – (2b + r)
6b + 4r - 2b - r
4b + 3r
Answer:
yo
Step-by-step explanation:
this was the sample response on edge
The student did not distribute the negative when subtracting. Distributing the negative, the expression is equal to 6b + 4r – 2b – r. Then use the commutative property to rewrite it as 6b – 2b + 4r – r. Then you can use the distributive property to write as (6 – 2)b + (4 – 1)r, which simplifies to 4b + 3r.
Please hurryyyyy !!!! What's the slope and y intercept of 4y = 2x - 12
Answer:
slop is 0.5 and intercept of y is -3
Answer:
½ is the slope,-3 is the intercept
Step-by-step explanation:
now to find the slope and intercept
we use the equation,
y=mx + c
where m is the slope
and c is the y intercept
so we compare 4y=2x-12 to the equation
but we first have to make y the subject of the equation in the question – 4y is already the subject –
y=2x-12/4
y=2x/4 -3
comparing...
we see that m is 2/4=½ c= -3

Answer:
1. and 2. I belive are true sorry if wrong
Step-by-step explanation:
The functiona f(x) and g(x) are shown on the graph.
What is g(x)?
f(x)
10
-5
g(x)
A
-10
A. 9(x) = -x2 - 4
B. g(x) = -x + 4
c. g(x) = (-x)² - 4
D. g(x) = (-x)2 + 4
Answer:
A. g(x) = -[tex]x^{2}[/tex] - 4
Step-by-step explanation:
f(x) is flipped, so [tex]x^{2}[/tex] becomes -[tex]x^{2}[/tex].
After being flipped, the graph is move down 4 units.
Therefore, g(x) = -[tex]x^{2}[/tex] - 4

If a 2ft stick in the ground casts a shadow of 0.8ft, what is the height of a tree that casts a shadow that is 14.24ft?
Answer:
35.6 feets
Step-by-step explanation:
To obtain tree height :
(Height of stick / shadow of stick = height of tree / shadow of tree)
Height of stick = 2 feets
Shadow of stick = 0.8 feets
Shadow of tree = 14.24 feets
Height of tree = h
(2 / 0.8 = h /14.24)
Cross multiply
0.8h = 14.24 * 2
0.8h = 28.48
h = 28.48 / 0.8
h = 35.6 feets
