Answer:
8 cm
Step-by-step explanation:
The formula of circumference is c= πd------(1)
where C = circumference, π = 3.14 and d = diameter
as we know that diameter is equal to d= 2r
put the diameter formula in eq(1)
we get c= π2r-------(2)
from eq (2) separate r means radius
hence, r= c/(π2)------(3)
put the values in eq(3)
and radius is equal to 8 cm.

Step-by-step explanation:
5.4 Find roots (zeroes) of : F(x) = 2x2 + 1
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 2 and the Trailing Constant is 1.
The factor(s) are:
of the Leading Coefficient : 1,2
of the Trailing Constant : 1
Final result :
2x • (2x2 + 1) • (5x - 3)

Therefore center is k.
Radius:-The distance from the center of the circle to any point on it's circumference
Radius is KJ,KL,KI
Chord :-The chord of a circle can be defined as the line segment joining any two points on the circumference of the circle.

Question 3 V (t) 30(1.05), where t is the time, in years, since opening the account Connie deposits $30 into an account. The value of the account, in dollars, can be modeled as To the nearest cent, what is the average rate of change in the value of the account for the first 3 years? A $0.63/year B $1.58/year С $3.15/year thing D $4.73/year
Answer:
b
Step-by-step explanation:
The average rate of change in the value of the account for the first 3 years is, $3.15/year. So Option C is correct.
What is the rate?Rate is a ratio of change in one quantity w.r.t. change in another quantity. The net change in one quantity is written as, Δy and the net change in another quantity is written as, Δx.
So formula for the rate is,
m = change in one quantity/change in another quantity = Δy/Δx
The average rate of change in the value of the account for the first 3 years can be calculated as follows:
Let t = 0 be the time when the account is opened,
and t = 3 be the end of the third year.
The value of the account at t = 0 is V(0) = 30,
and the value of the account at t = 3 is
V(3) = 30(1.05)³
The average rate of change in the value of the account over the first 3 years is given by the formula:
⇒ (V(3) - V(0)) / (3 - 0)
⇒ (30(1.05)³ - 30) / 3
⇒ $3.15/year
Hence, the average rate of change in the value of the account over the first 3 years is approximately $3.15/year

Mr. Mole's burrow lies 5 55 meters below the ground. He started digging his way deeper into the ground, descending 3 33 meters each minute. Graph the relationship between Mr. Mole's elevation relative to the ground (in meters) and time (in minutes).
At the 95% confidence level, the margin of error for this survey, expressed as a proportion, is approximately 0.0288.
To calculate the margin of error for a survey expressed as a proportion, we need to use the formula:
Margin of Error = Critical Value [tex]\times[/tex] Standard Error
First, let's find the critical value.
For a 95% confidence level, we can refer to the standard normal distribution (Z-distribution) and find the z-value associated with a 95% confidence level.
The critical value for a 95% confidence level is approximately 1.96.
Next, we need to calculate the standard error.
The standard error for a proportion can be computed using the formula:
Standard Error [tex]= \sqrt{((p \times (1 - p)) / n)}[/tex]
Where:
p = proportion of respondents in favor of the plan
n = sample size
In this case, the proportion in favor of the plan is 37/185 = 0.2 (rounded to the nearest thousandth).
The sample size is 185.
Now we can calculate the standard error:
Standard Error [tex]= \sqrt{((0.2 \times (1 - 0.2)) / 185)}[/tex]
Simplifying further:
Standard Error ≈ [tex]\sqrt{((0.04) / 185)}[/tex]
Standard Error ≈ [tex]\sqrt{(0.0002162)}[/tex]
Standard Error ≈ 0.0147 (rounded to the nearest thousandth)
Finally, we can calculate the margin of error:
Margin of Error = 1.96 [tex]\times[/tex] 0.0147
Margin of Error ≈ 0.0288 (rounded to the nearest thousandth)

Answer:
Option D = 16π/3 ft
Step-by-step explanation:
Arc length formula is written Mathematically as:
Arc length = 2πr × θ /360
r = 4 ft
θ = Central angle in degrees = 240°
2 × π × 4 × 240/360
8π × 240/360
8π × 20/30
16π/3 ft
So, the arc length is 16π/3 ft

Given square ABCD, which line segment could be an image of side AD using only a translation?
Answer:
The second one
Step-by-step explanation:
Line segment BC will be an image of side AD using only a translation.
Option 2 is true.
What is Translation?
A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Given that;
A figure ABCD is a square.
Now,
Since, ABCD is a square.
So, All sides of square ABCD are equal to each other.
Since, A translation occurs when a figure is moved from one location to another location without changing its size or shape.
Thus, Line segment BC will be an image of side AD using only a translation.
Therefore, Line segment BC will be an image of side AD using only a translation.

C. 10 yards
D. 30 yards
Answer:
C. 10
Step-by-step explanation:
5+5=10
10+10=20
