Find the radius of a circle with a circumference of 23.55 feet. Use 3.14 for
Answer:
3.75
Step-by-step explanation:
The radius of the circle will be (11.775/π).
What is the area of a circle? What is an exponential function? Differentiate between equation and expression? area of circle : The area of a circle is equivalent to -[A] = πr² = πd²/4
function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the circumferance of the circle is 23.55 feet.
We can write -
2πr = 23.55
r = (23.55/2π)
So, the area of the circle will be -
{A} = πr²
{A} = π x (23.55 x 23.55)/4π²
{A} = (555/4π)
{A} = 138.75/π
r = (23.55/2π)
r = (11.775/π)
Therefore, the radius of the circle will be (11.775/π).

What is the 7th term in the sequence?
Answer:
[tex]T_7 = 136.6875[/tex]
Step-by-step explanation:
Given
12, 18, 27, ..
Required
Determine the 7th term
The above sequence shows a geometric sequence and the nth term is calculated by:
[tex]T_n = a * r^{n-1[/tex]
r is calculated by:
[tex]r = \frac{T_2}{T_1}[/tex]
[tex]r = \frac{18}{12}[/tex]
[tex]r = 1.5[/tex]
[tex]a = 12[/tex] --- First term
[tex]n = 7[/tex]
So:
[tex]T_n = a * r^{n-1}[/tex]
[tex]T_7 = 12 * 1.5^{7-1[/tex]
[tex]T_7 = 12 * 1.5^6[/tex]
[tex]T_7 = 136.6875[/tex]

From the given information:
We are to find the following:
1)
Directional hypothesis: The directional hypothesis is the groups with different bedroom lightning conditions having a different proportion of eyesight proportions.
2)
The non directional hypothesis is each group having the same proportion of eyesight problems regardless and independent of the condition of the bedroom lightning.
3)
Control group: Children that slept in darkness
4)
Experimental groups: Children that slept in night light and those that slept with lamp.
5)
Independent variable: Light condition of the bedroom
Dependent variable: Eye sight problem.

Mark thinks the equation y= 4^x will match the solid
graph. Mia thinks it will match the dotted graph.
Who is correct?
Mark
Mia
Both
Neither
Explain your thinking
Answer:
Mark
Step-by-step explanation:
because when x = 0; y = 1
x=1; y=4
and those points are on the solid line graph.
The thought of Mark is correct.
What are Exponential Functions?Exponential functions are functions where the independent variable, x is in the exponent.
Given a graph.
It has a solid line and a dotted line.
The given equation is, y = 4ˣ.
In order to find which graph shows the equation, find the points that the graph of the equation will pass through.
When x = 0, y = 4⁰ = 1
Solid graph passes through (0, 1).
Hence Mark is correct.

b. -75
c. 75
d. 105
9514 1404 393
Answer:
b. -75°
Step-by-step explanation:
Point A moves from (-4, -3) to (-4, 3). We can find the angle of rotation several ways. One is to consider the tangent of the angle relative to the x-axis.
Point A is on a line that makes an angle to the x-axis of ...
∠A = arctan(-3/-4) = 36.9°
Point A' is on a line that makes an angle to the x-axis of ...
∠A' = arctan(3/-4) = -36.9°
Then the change in angle is ...
∠A' -∠A = -36.9° -36.9° = -73.8°
The closest answer choice is ...
b. -75°

b) Ronu's age after 2 years
c) Shaani's present age
d) Shaani's age after 2 years
What hould be added to 100 to get - 132
Answer:
x = -232
Step-by-step explanation:
Ronu's present age is "x “years and her sister Shaani's present age is twice of Ronu's age.
(a) Ronu's present age = x years
(b) Ronu's age after 2 years = (x+2) years
(c) Shaani's present age = 2x years
(d) Shaani's age after 2 years = (2x+2) years
Let x should be added to 100 to get -132.
x+100 = -132
x = -100-132
x = -232
Hence, -232 must be added to 100 to get -132.

What are some of the factors that would influence your insurance costs?
OA. Your gender.
OB. Where you live.
OC. The type of car you drive.
OD. All of the above.
Answer:
D. All of the above
Step-by-step explanation:
Insurance costs are influenced by any factor that can reasonably be tied to the cost of claims made against an insurance policy. These costs are carefully analyzed by insurance companies to determine correlations that may be influential.
__
In general, women have different driving habits than men, so gender has an influence on insurance costs.
Some areas of a city have different statistics related to vandalized or stolen vehicles, so may influence insurance costs. Certain areas may have different accident statistics, or may experience different kinds of accidents, so repair costs may differ by where you live or where you drive.
Some cars are more expensive to repair than others. Any car with custom features (stereo, upholstery, paint) will likely cost more to repair (and may be subject to more vandalism).
So, all of the above influence insurance costs.
