Answer:
BC_______________________________
A is wrong because radians really refers to the arc with respect to the angle. The opposite is true with A.
D is wrong because the arc is actually bigger than the radius given 1.5 radians.
E is wrong because the area of the whole circle is defined as 2π radians, 1.5 rad × 1.5 = 2.25 rad is (405/π)° and 2π radians is 360° (2π × 180 / π)°.
F is wrong because the circumference of a circle is 2πr.

what is 21 5/8% as a decimal
Answer: 21.625
Step-by-step explanation:
The percentage of 21 (5/8)% in decimal form is 173/800.
We have,
The percentage means the required value out of 100.
It is calculated by dividing the required value by the total value and multiplying by 100.
The given percentage expression.
21(5/8) %
Divide by 100 to remove the %.
This can be written as,
21(5/8) / 100
Now,
21(5/8)
= (21 x 8 + 5) / 8
Simply the fraction.
= 173/8
Now,
173/8 / 100
Simplify the fraction.
= 173/800
Thus,
The percentage of 21 (5/8)% in decimal form is 173/800.

A quadrilateral has angles that measure 115, 97, and 68. What is the measure of the missing angle? Plz help me I don't know the answer!!!
A.45
B. 115
C.68
D.80
Answer:
Step-by-step explanation:
The sides of a quadrilateral always add up to 360°.
Missing angle = 360-115-97-68 = 80°
Answer:
D. 80°
Step-by-step explanation:
A quadrilateral always add up to 360°
To find the missing value we first have to add the given number up:
115 + 97 + 68 = 280°
Now we minus our value from 360° :
360° - 280° = 80°

A bag contains 7 red marbles, 8 blue marbles and green marbles. If two marbles are drawn out of the bag, what is the exact probability that both marbles drawn will be red?
Answer:
For this problem you will be multiplying 3 probabilities together: P(#1 is blue)*P(#2 is blue)*P(#3 is blue). For the first probability, we just need to divide the number of blue marbles by the total number of marbles which would be 8/18. For the 2nd probability, we need to remember that we have already removed 1 blue marble so that the number of blue marbles remaining is now 7 and the total number of marbles is now 17 to give us 7/17. We would repeat this process to get the third probability and then multiply all the probabilities together.
-1.32+x=1
-1 -1
Not sure about this??
Answer:

Solve the triangle. A = 46°, a = 31, b = 27
Answer:
A=46 degrees, B=33.4 degrees, C=100.6 degrees
a=34, b=27, c=48.2
Step-by-step explanation:
(a/sin(A)) = (b/sin(B)) = (c/sin(C))
we are given
(34/sin(46)) = (27/sin(B))
34sin(B) = 26sin(46)
34sin(B) = 18.702834809
sin(B) = 0.550083377
note use inverse sin function to find angle B
B = 33.372733167 approx 33.4 degrees then
C = 180 - (46 + 33.4) = 100.6
Then, (b/sin(B)) = (c/sin(C))
27/0.550083377 = c/0.982935349
0.550083377 * c = 27 * 0.982935349
0.550083377 * c = 26.539254427
c = 48.245876056 approx 48.2 .
Lastly, you get: A=46 degrees, B=33.4 degrees, C=100.6 degrees
a=34, b=27, c=48.2

The reciprocal parent function is reflected across the x- axis, then translated 5 units right and 7 units down . Write an equation that could represent this new function , then identify the asymptotes
Answer:
Equation: [tex]f'"(x) = -\frac{1}{x-5}-7[/tex]
Asymptotes: [tex](x,y) = (5,-7)[/tex]
Step-by-step explanation:
Given
Let the reciprocal function be:
[tex]f(x) = \frac{1}{x}[/tex]
First, it was reflected across the x-axis.
The rule is: (x,-y)
So, we have:
[tex]f'(x) = -\frac{1}{x}[/tex]
Next, translated 5 units right.
The rule is: (x,y)=>(x-5,y)
So:
[tex]f"(x)= -\frac{1}{x-5}[/tex]
Lastly, translated 7 units down.
The rule is: (x,y) => (x,y-7)
So:
[tex]f'"(x) = -\frac{1}{x-5}-7[/tex]
To get the vertical asymptote, we simply equate the denominator to 0.
i.e.
[tex]x - 5 = 0[/tex]
[tex]x = 5[/tex]
To get the horizontal asymptote, we simply equate y to the constant.
i.e.
[tex]y = -7[/tex]
[tex](x,y) = (5,-7)[/tex]

Answer:
3/4 or 75%
Step-by-step explanation:
There are twelve possible outcomes. (4 green for each of the three orange).
The only combinations that add up to six or more are 2&4, 3&3 and 3&4.
That’s 3 out of 12. So 9 out of 12 combinations will add up to less than 6.
