Solve for x on [0, 2pi]
secx-cscx=0
I know what the answer is but can someone help me with the process of finding it?
The required solution to the trigonometry equation is x = π/4 + π n.
The equation of trigonometry functions is given in the question as
secx - cscx = 0
We have to determine the solution to the given equation
As per the question, we have
⇒ secx - cscx = 0
⇒ 1/cosx - 1/sinx = 0
⇒ (-cosx + sinx)/cosxsinx = 0
Using property : f(x)/g(x) = 0 ⇒ f(x) = 0
⇒ -cosx + sinx = 0
Divided by cosx into the equation,
⇒ -1 + tanx = 0
⇒ tanx = 1
The general solution for tan tanx = 1 is

donnell is doing market research for a major brand by surveying customers at a local mall the probability of a customer agreeing to take the survey is 22% what is the probability that one of the first five sustomers agrees to take the survey
The probability that one of the first five customers agrees to take the survey is 71%
Here we have to use binomial distribution.
What is binomial distribution?
A common probability distribution known as the binomial distribution simulates the likelihood of getting one of two outcomes given a set of parameters. It provides a summary of the number of trials when each trial has an equal chance of producing a particular result.
A binomial distribution with the following formula could be used to represent the proportion of clients who agree to participate in the survey out of 5:
X ~ Bin (n = 5, p = 0.22)
Thus the probability is computed as:
P(X >= 1) = 1 - P(X = 0) = [tex]1 - (1-0.22)^5[/tex]
= 0.71
The required probability in this case is therefore 71%.

In a circle, an angle measuring 7.1 radians intercepts an arc of length 2.4. Find the radius of the circle to the nearest 10th.
The radius of the circle with arc length of 2.4 and subtended angle at the center, 7.1 radians is 0.3
What is an arc of a circle?The arc of a circle is defined as the part or segment of the circumference of a circle. A straight line that could be drawn by connecting the two ends of the arc is known as a chord of a circle. If the length of an arc is exactly half of the circle, it is known as a semicircular arc.
length of arc = 2.4
if 7.1 rad is the angle subtended by the intercepts of the arc
But [tex]\pi[/tex] rad = 180°
so 7.1 rad in degree = [tex]\frac{7.1}{\pi }[/tex] x 180 which is [tex](\frac{1278}{\pi } )^{} }[/tex] degree which is [tex]\alpha[/tex]
Length of an arc = [tex]\frac{\alpha }{360} * 2\pi r[/tex]
2.4 = [tex](\frac{1278}{\pi } )^{} }[/tex] x [tex]\frac{1}{360}[/tex] x 2 x [tex]\pi[/tex] x r
The equation reduces to

In winter, apple prices suddenly increase by €0.75 per kilogram. Sam bought 3 kilograms of apples for the new price of €5.88.
Answer:
p represents the original per pound price
3p represents the cost of three pounds
3p + 3(0.75) = 5.88 multiply
3p + 2.25 = 5.88 subtract 2.55 from both sides
3p = 3.63 divide both sidesby 3
p = 1.21
The original price was $1.21 per pound.

Does the point (-7, 5) satisfy the inequality y > -3/7x +2
Answer:
Yes, the point (-7, 5) satisfies the inequality y > -3/7x + 2
Step-by-step explanation:
Plug in the values to the inequality and verify if it is true:
x = -7, y = 5
5 > (-3/7*-7) + 2
5 > (-3/-49) + 2
5 > 3/49 + 2
5 > 101/49
The inequality above is true (5 is greater than 101/49 [101/49 is about 2.06]), so the point (-7, 5) satisfies y > -3/7x + 2

Kari's renter's insurance is set to increase by 10% per month after she files a theft claim. If her premium is $35 per month, what
will her new premium be?
$45 per month
$31.50 per month
$38 per month
$38.50 per month
Answer: $38.50 per month
Step-by-step explanation: We have to find 10% of 35 and add it to 35. This is because 10% of 35 is the amount that will increase so adding that to the original 35 will be her new premium. 10% of 35 is $3.50 and $3.50 + $35 is $38.50. This means her new premium is $38.50 per month.

In a coordinate plane, a line has two points A and B with the coordinates A(4,n) and B(10,6n). In the same coordinate plane, a different line has two points C and D with coordinates C(−3,−6) and D(9,8n). For what value of n are the two lines parallel?
For the two lines to be parallel, the value of n must be 3
How are two lines parallel in a coordinate?When two straight lines are plotted on the coordinate plane, we can tell if they are parallel from the slope, of each line. If the slopes are the same then the lines are parallel.
The slope of each line is calculated as (y2-y1)/x2-x1
for line AB, the slope = (6n-n)/10-4 = 5n/6
for line CD, the slope= 8n-(-6)/9-(-3)=( 8n+6)/12
for AB and CD to be parallel,
5n/6 = (8n+6)/12
multiply both sides by 12
10n= 8n+6
collect like terms
10n-8n= 6
2n= 6
n= 6/2= 3
therefore for the value of n= 3 line CD and AB are parallel.

The confidence interval for a proportion should be constructed since the variable of interest is a person's opinion, which is a qualitative variable.
What is a qualitative variable?A trait that cannot be quantified is referred to as a categorical variable (also known as a qualitative variable).
Nominal or ordinal categorical variables are also acceptable.
Since the variable of interest is a person's opinion, which is a qualitative variable, the confidence interval for a proportion should be built.
Statistical Variables Qualitative variables also referred to as categorical variables are variables without a built-in sense of hierarchy.
As a result, they are quantified using a nominal scale.
For instance, a qualitative variable is a name as well as hair color (Black, Brown, Gray, Red, Yellow).

The largest possible value for the decimal $a. B + c. D$ us:
9.7 + 8.6 which results to 18.3.
Given that a, b, c, and d are different numbers (from 1 to 9), we are to find the largest possible value of a.b + c.d.
This problem can be answered by trial and error and with some logic. Clearly, a to d cannot be at the lower end of the values (1 to 5). Since the digits must be different, it can be a combination of digits from 6 to 9.
It is rather tempting to say that the 9.8 + 7.6 would yield the highest possible sum (=17.4) but this is incorrect. Since it is the sum of two numbers with a decimal, we have to maximize on the ones digit first before maximizing the tenths digit. Therefore: the combination of numbers must then be:
9.7 + 8.6 which results to 18.3
9.6 + 8.7 yields 18.3 as well.

Let h be the height and r be the radius.
Then, h+r = 12

Volume of the cylinder (V):
V=πr²h

Differentiate with respect to r , we get
dv/dr = 24 πr - 3πr²
Find r by taking dv/dr=0
24 πr - 3πr² = 0
3π ( 8r - r² ) = 0
8r = r²
r=8
Again differentiating, we get
d²V/dr² = 24π - 6 π r
When r=8, 24π - 48 π <0
So, V is maximum at r= 8 inches
And h= 12-8= 4 inches
Hence, the required volume of the cylinder = π8²*4 = 256π cubic inches

Answer:
3. 70 degrees
4. 110 degrees
Step-by-step explanation:
3. The angles are mirrored on both sides
4. A straight line is equal to 180 degrees so if <AED is 70 degrees then you would do 180-70 to get 110 degrees
