The radius of a circle is 9 centimeters. What is the length of a 96° arc?
Answers
Wrong answer but unique technique to consider: i think i inversed the ratio but i think its right
Pi = circumference/diameter
X/18 centimeters =pi
X is whole circumference 18pi cm you need to convert radians to degrees and get partial arc1 pi is 180 degrees so ratio of
Was the error inverse ratio 96/180?
180/96*18
Error here factor of 72 not 96
18*2*3*3*10/2*3*12 [edit factor should be 2 4 12 ]cancel out factors to reduce
180/4 =45cm
Correction
180*3/4*4
So answers i got are 45 cm corrected as 33.75 cm still way more than total circumference of 18pi 56cmapprox and 9.6cm both are wrong according to calculator online
Please note I canceled out pi by using is degree ratio
Double check i may be wrong
Step-by-step explanation:
Answer:
Solution, we have,
Degree measure ([tex]\theeta[/tex][tex]\alpha[/tex]) = 96° = 96[tex]\pi[/tex]/180
Radius (r) = 9cm
Length of arc (l) = ?
Now,
∝ = l /r
or, [tex]\frac{96\pi }{180}[/tex] =[tex]\frac{l}{9}[/tex]
or, l =[tex]\frac{(96\pi )(9)}{180}[/tex] =4.8[tex]\pi[/tex]cm

Write the equation of the line in point-slope form that goes through the points (0, 1) and (2, 7)
Answers
Answer:
point - slope form
y - 1 = 3 (x-0)
Step-by-step explanation:
step(i):-
Given points are (0,1) and (2,7)
The slope of the line
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
[tex]m = \frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{7-1}{2-0} = \frac{6}{2} = 3[/tex]
m =3
Step(ii):-
point -slope form
y - y₁ = m(x-x₁)
Equation of the straight line passing through the point (0,1) and having slope 'm' = 3
y - 1 = 3 (x-0)
y -1 = 3x
3x - y +1=0
Equation of the straight line passing through the point (0,1) and having slope 'm' = 3 is 3x -y +1=0

Solve, showing and explaining all steps in the process. 7(y + 2) – (2y – 5) = 41
Answers
Answer:
Step-by-step explanation:
Remove parentheses.
7(y+2)-2y+5=41
2 Expand.
7y+14-2y+5=41
3 Simplify 7y+14-2y+5 to 5y+19.
5y+19=41
4 Subtract 19 from both sides.
5y=41-19
5 Simplify 41-19 to 22
5y=22
6 Divide both sides by 5.
y= 22/5
Answer:
y=6.4
Step-by-step explanation:
distribute:
7y+14-2y-5=41
then combine like terms:
5y+9=41
subtract 9 from both sides:
5y=32
divide 5 by both sides:
y=6.4

2) You traveled 210 miles in 3.5 hours.
How many miles will you travel per hour?
Answers
Answer:
= 56.7 miles per hour
Step-by-step explanation:
Step-by-step explanation:
To find the average speed for the entire journey, we need to find the entire distance and the total time
Entire distance = 210 miles + 130 miles = 340 miles
Total time = 3.5 hours and 2.5 hours = 6 hours
Average speed = distance/ time = 340 miles/ 6 hours
= 56.66666666666 miles per hour
Rounding to the nearest tenth
= 56.7 miles per hour
Answer:
60 miles
Step-by-step explanation:
Step 1:210=3.5
x =1
Step 2: cross multiply3.5×x= 210×1
3.5x=210
Step 3: divide both sides by the coefficient of x which is 3.53.5x/3.5=210/3.5
x=60

Consider an example of an apartment: The number of bedrooms, bathrooms, and the floor of an apartment determines its price. Which is the dependent variable in this example
Answers
Answer: The price of the apartment.
Step-by-step explanation:
We know that for a given apartment, the number of bedrooms, bathrooms, and floor determines the price.
Then we could define the variables:
x = number of bedrooms.
y = number of bathrooms
z = floor.
And define the price of the apartment as a function of these variables:
p(x, y, z) = price
Then the independent variables are x, y, and z.
And the dependent variable (this is, the variable that changes in response to the changes in the independent variables) will be the price of the apartment.
Using function concepts, it is found that the dependent variable in this example is the price.
The standard format of a function is: [tex]y = f(x)[/tex].In which each value of y is a function of one value of x, and thus, x is the independent variable and y is the dependent variable.In this problem, price depends of the number of bedrooms, bathrooms, and the floor of an apartment, hence, the function is:
[tex]p = f(be, ba, fl)[/tex]
Which means that the dependent variable is the price.
