show that cos 30 + 2 tan 60 can be written in the form k where k is an integer
Answer:
k = 4.33
Step-by-step explanation:
Cos 30 = 0.8660
Tan 60 = 1.732
2 Tan 60 = 2 (Tan 60)
2 Tan 60 = 2 (1.732)
2 Tan 60 = 3.464
Cos 30 + Tan 60 = 0.8660 + 3.464 = 4.33

a circle has a circumference of 615.44615.44615, point, 44 units. what is the radius of the circle? use 3.14 for \piπpi and enter your answer as a decimal.
A circle with a circumference of 615.44 units has a radius of 98 units.
A circle is a round closed figure where all its boundary points are equidistant from a fixed point called the center.
The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant [tex]\pi[/tex] and the diameter of the circle.
C = [tex]\pi[/tex]D
The diameter (D) is the distance across the circle through the center, it is a line that meets the circumference at both ends and it needs to pass through the center. On the other hand, the radius (r) of a circle is the distance from the center of a circle to any point on the circumference of the circle. Radius is half of the diameter.
If r = 1/2 D, then
D = 2r
Evaluating the value of Din the formula of the circumference,
C = [tex]\pi[/tex](2r)
C = 2[tex]\pi[/tex]r
Using the value of [tex]\pi[/tex] as 3.14 and the circumference as 615.44 units,
evaluate the equation.
C = 2[tex]\pi[/tex]r
615.44 = 2(3.14)r
r = 615.44/ (2*3.14)
r = 98 units
Therefore, the radius of the circle is 98 units.

the sum of four numbers is 1,764. oneof the numbers, n, is 40% more than the sum of the other three numbers. what is the value of n?
Four numbers has a sum of 1764 and the value of one of those numbers is 1029.
Use algebraic expressions to solve for the value of n.
Algebraic expression is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc).
One of the four numbers is already denoted as variable n. Let m be the sum of the three other numbers.
If the sum of the four numbers is 1,764, then:
n + m = 1764
If n is 40% more than the sum of the other three numbers, then:
n = 40% m + m
n = 1.4 m
Substitute n from the 2nd equation to the 1st equation.
n + m = 1764
1.4 m + m = 1764
2.4 m = 1764
m = 735
Recall that n = 1.4 m.
n = 1.4 (735)
n = 1029

a national survey conducted among a simple random sample of 1,507 adults shows that 56% of americans think the civil war is still relevant to american politics and political life.
a)
[tex]z=4.658\\p_v=P(z > 4.65)=1-P(z < 4.65)=1.581x*10^{-6}[/tex]
b) By assuming a significance level of α = 0.05 and observing that [tex]p_v[/tex] > α, we can reject the null hypothesis at this level of significance. And in this instance, it makes sense that more than 50% of Americans believe that the Civil War still has an impact on American politics and political life.
c) The confidence interval at 90% would be shown (0.527;0.593).
About 54% to 59% of all Americans, in our opinion, believe that the Civil War is still significant today.
What is a survey?A survey is a set of questions used in human subject research with the goal of gathering specific information from a certain population. Surveys can be carried out via the phone, by mail, online, at street corners, and even in shopping centers.
a)
1) The presented data and the notation "n=1507" refer to the random sample of Americans, "X" denoting the proportion of those Americans in the sample who believe that the Civil War is still significant to American politics and political life, and "p cap" denoting the estimated number of those Americans.
Since the problem specifies that majority α=0.05 represents the significance threshold, [tex]p_0[/tex] is the number that we wish to test (no given, but is assumed)
Z would stand for the statistic (interesting variable), and [tex]p_v[/tex] for the p value (variable of interest)
P is the percentage of the public that believes that the Civil War still has an impact on American politics and political life.
2) Useful concepts and formulas
The allegation that more Americans than 50% believe the Civil War is still significant to American politics and political life needs to be tested through a hypothesis (Majority). :
Alternative Hypothesis: p[tex]\geq[/tex] 0.5
Null Hypothesis: p[tex]\leq[/tex] 0.5
The proportion is thought to have a normal distribution.
This test for the percentage of union membership has one tail higher.
Verify whether the sample conforms to the presumptions required for the test to be applied.
a) The random sample must be representative; in this situation, there is no mention of this issue, but it is safe to presume that it exists.
b) The sample size must be sufficient.
[tex]np_0=1507*0.5=753.5 > 10\\n(1-p_0)=1507*(1-0.5)=753.5 > 10[/tex]
3. Determine the statistic.
The formula used to calculate the statistic is as follows:
[tex]z=\frac{p-p_0}{\sqrt{\frac{p_0(1-p_0)}{n} } }= \frac{0.56-0.5}{\sqrt{\frac{0.5(1-0.5)}{1507} } }=4.658[/tex]
P value= [tex]p_v=P(z > 4.65)=1-P(z < 4.65)=1.581*x*10^{-6}[/tex]
According to the alternative hypothesis, the following would be the p value:
P value= [tex]p_v=P(z > 4.65)=1-P(z < 4.65)=1.581*x*10^{-6}[/tex]
Using this formula, the confidence interval would be determined.
p ± [tex]z_{\frac{\alpha }{2}}\sqrt{\frac{p(1-p)}{n} }[/tex]
With the value of [tex]\alpha[/tex] and [tex]\alpha _2[/tex], we can get the quantile necessary for the interval in the normal standard distribution for the 90% confidence interval.
[tex]z_{\frac{\alpha }{2} }=2.58[/tex]
adding the following to the formula for the confidence interval:
[tex]0.56-2.58\sqrt{\frac{0.56(1-0.56)}{1507} } = 0.527\\0.56+2.58\sqrt{\frac{0.56(1-0.56)}{1507} } = 0.593[/tex]
Also provided would be the 90% confidence interval (0.527;0.593).
About 54% to 59% of all Americans, in our opinion, believe that the Civil War is still significant today.
And because the interval does not contain the value of 0.5, we can conclude that, at a 90% level of confidence, the percentage of Americans who believe that the Civil War is still relevant to American politics and political life is higher than 0.5. This result is consistent with the result of part b.

The length of the hypotenuse AB is approximately 6.53 units.
In a right angled triangle the side opposite the right angle or the largest side is called the hypotenuse of the triangle.
The length of the hypotenuse is calculated using trigonometric ratios. If in a right-angled triangle, the base angle is θ then:
sin θ = perpendicular ÷ hypotenusecos θ = base ÷ hypotenusetan θ = perpendicular ÷ baseIn the given figure we see in ΔABC
AB is the hypotenuse. ∠BAC = 40 ° AC is the base and BC is the perpendicular.
(The side that contains the given angle is the base and the side opposite the given angle is taken as perpendicular)
Now cos ∠BAC = BC ÷ AB
or, cos 40° = 5 ÷ AB
or, AB = 6.527...
or, AB ≈ 6.53
Hence the value of AB is approximately 6.53 units.

A submarine is only allowed to change its depth by rising toward the surface in 60-meter stages. It starts off at -340 meters.
At what depth is it after:
1 stage meters
2 stages meters
4 stages meters
How many full stages will it take to return to the surface?
Answer:
Can you only pick one answer?
Answers:
depth after 1 stage is -280 meters depth after 2 stages is -220 meters depth after 4 stages is -100 meters how many stages to return to the surface? 6 stages==========================================================
Explanation:
After 1 stage, the depth is -340+60*1 = -280 meters. In other words, it's 280 meters below the surface.
After 2 stages, the depth is now -340+60*2 = -220 meters
After 4 stages, the depth is -340+60*4 = -100 meters
After n stages, the depth is -340+60n. Set this equal to zero and solve for n.
-340+60n = 0
60n = 340
n = 340/60
n = 5.667 approximately
This rounds to n = 6
After n = 5 stages, the depth is -340+60n = -340+60*5 = -40 meters
After n = 6 stages, the depth is -340+60n = -340+60*6 = 20 meters, so the submarine is now at the surface. Of course the sub cannot fly to a height of 20 meters above the ocean's surface, so the highest it can go is 0 meters at the surface itself. This means the 6th stage is a movement of 40 meters (instead of 60 meters).

Done
The volume of the sphere is 2144.7cm³.
Given that a sphere with radius 8 cm.
As we all know that the volume of sphere is 4/3πr³.
We will find the volume of sphere by substituting the value of radius in the formula, we get
Volume=4/3 πr³
Now, we will substitute r=8 cm in above formula, we get
V=(4/3)π(8 cm)³
V=(4/3)π(512)cm³
Now, we will simplify this by multiply by 4, we get
V=(2048/3)πcm³
Now, we will simplify it by dividing it with 3, we get
V=682.66π cm³.
As we know, the value of π is 3.14.
So, we will substitute this value and simplify it, we get
V=682.66×3.14
V=2144.66 cm³
Hence, the volume of the sphere when the radius is 8cm is 2144.7 cm³.
