After evaluating the limit we have came to find that the limit of      [tex]\lim_{x\rightarrow \Pi }cos(x)[/tex] as x approaches π is –1

As an input or as an index approaches a specific value in mathematics, a limit is the value that the function, sequence, or index approaches. The definitions of continuity, derivatives, and integrals all require limits, which are fundamental to calculus and mathematical analysis.

In addition to having a connection to the category theory concepts of limit and direct limit, the idea of a limit of a sequence is further generalized to include the idea of a limit of a topological network.

A limit of a function is typically expressed in formulas as

[tex]{\displaystyle \lim _{x\to c}f(x)=L,}[/tex]

To find the limit

⇒ [tex]\lim_{x\rightarrow \Pi }cos(x)[/tex]

= cos(180° – 0°)

So to know that, we can find the intercept in the y axis by replacing x=0 so:

So if you see the functions the only one that intercept the y axis in -4, then the solution is option (D)

The table shows that each output(y) is obtained by multiplying each input(x) value by 2.

therefore, the answer is the first option

Answer:

=24.19×10^14

Step-by-step explanation:

we will just all add to get the distance

=4.1×10²×5.9×10¹²

=4.1×5.9×10²×10¹²

=24.19×10^14

We're only given one angle: the angle that measures 35°.

This angle and ∠1 are supplementary angles, meaning they add up to 180°. To find ∠1, subtract 35 from 180:

180 - 35 = 145°

The angle and ∠2 are corresponding angles, meaning they are on the same sides of the diagonal line and the transversal.

Corresponding angles are always equal.

Therefore, ∠2 = 35°.

∠1 = 145°

∠2 = 35°

Answer:

Here is the answer: sin(3π/2) = -1

So 3π/2 is the correct choice.

The expression of the confidence interval (78.5, 154.7) in the form of x¯ ± ME is; CI = 116.6 ± 38.1

We are given the confidence interval as;

CI = (78.5, 154.7)

Now, we want to express the given confidence interval in the error bound form which is; x¯ ± ME

where;

x¯  is sample mean

ME is margin of error

Now, the boundaries of the interval as two points is the midpoint between them which would be (78.5 + 154.7)/2 = 116.6.

This is right in the middle of 78.5 and 154.7.

This value of 116.6 is the sample mean represented by x¯, since x¯ is in the middle of the interval. This means that 78.5 and 154.7 are the same distance (the margin of error, ME) away from 116.6. .

116.6 - 78.5 = 38.1 and 154.7 - 116.6 = 38.1

Thus, the expression is;

CI = 116.6 ± 38.1

The equation of the line which is perpendicular and goes through the point (8,2) is slope-intercept form of y = x - 6.

What is slope-intercept form?

The equation of the line which is perpendicular and goes through the point (8,2) is y = x - 6

The equation of the required line in slope-intercept form is expressed as:

y-y0 = m(x-x0) where:

m is the slope

(x0, y0) is the point on the lin

Given the equation of the line as y = -x

Get the slope of the line

mx = -x

m = -1

Since the required line is perpendicular to this line, the required slope will be 1 (M = -(-1/1))

y-y0 = m(x-x0)

y - 2 = 1(x-8)

y - 2 = x - 8

y = x - 8 + 2

y = x - 6

Hence the equation of the line which is perpendicular and goes through the point (8,2) is y = x - 6.

There are 3024, 9072 and 27216 baskets are produced in 4th,  5th and 6th days respectively.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A manufacturing unit produced 112, 336 and 1008 Easter baskets on days one, two and three.

Now,

On first day, there are 112 baskets.

And, On second day, there are 336 baskets.

So, Clearly 112 x 3 = 336

That's mean every day the number of produce baskets are three times the previous day.

So, On fourth day;

Number of Easter basket produce = 1008 x 3 = 3,024

On fifth day;

Number of Easter basket produce = 3,024 x 3 = 9,072

On sixth day;

Number of Easter basket produce = 9,072 x 3 = 27,216

Thus, There are 3024, 9072 and 27216 Easter baskets are produced in 4th,  5th and 6th days respectively.

Simple interest typically favors consumers who pay their bills or loans on time or early each month because it is frequently calculated on a daily basis. The loan's simple interest rate is 4.5%.

Simple interest typically favors consumers who pay their bills or loans on time or early each month because it is frequently calculated on a daily basis.

In the aforementioned student loan example, if you paid a $300 payment on May 1st, $238.36 would be applied to the principle. On April 20, if you made the same payment, $258.91 would be applied to the principal. Your main balance will decrease more quickly and the loan will be paid off faster than anticipated if you can make an early payment every month.

On the other hand, if you pay the loan back late, you pay more in interest than if you pay it on time. If your payment is due on May 1 and you make it on May 16 (using the same car loan example), you will be charged interest for 45 days at a cost of $92.46. Consequently, only $207.54 of your $300 payment is applied to the principal. If you frequently make late payments over the course of a loan, your final payment will be more than anticipated because the principal did not decrease at the anticipated rate.

Principal amount,

P=$5000

Future value,

A=$5900

Time,

t=4years

Let us determine the loan's simple interest rate:

A=P(1+rt)

5900=5000(1+r*4)

5900=5000(1+4r)

5900=5000*1+5000*4r

5900=5000+20000r

5900−5000=20000r

900=20000r

20000r=900

r=900/20000

r=9/200

r=0.045

r=0.045/100%

r=4.5%

The answer to the expression 120% (_____) 1 is:
120% > 1. See the explanation related to the percentage problem below.

A percentage is a figure or ratio stated as a fraction of 100 in mathematics. It is frequently indicated by the percent symbol, "%."

To overcome the above problem, we must transform the two numbers into the same form.

Because adding zeroes to the ending of a decimal does not modify the value, we know that 1 = 1.00.

To convert a decimal to a percentage, multiply it by 100 and add a percent sign.

1.00 * 100 = 100%

Hence, 1 = 100%

Because 120% is greater than 100%, it is right, therefore, to state that:
