The first digit of this number is 3², which is 9.
The Number is : 9xx
________
The second digit is: -2·(-4)=8.
The Number is : 98x.
________
The sum of all the digits is 18. This gives us an equation that we can solve in terms of x!
[tex]\multimap\sf{9+8+x=18}[/tex] (x is the digit we are looking for)
Now it takes a little arithmetic to find x :)
[tex]\multimap\sf{17+x=18}[/tex]. Just subtract 17 from both sides to find x!
[tex]\multimap\sf{x=1}[/tex]. And Now, can you see the number!
It's 981, of course :)
Hope this made sense to you!

What is the repayment amount after one month on a simple interest loan of $2,500 at 7% interest?
Payment Every Month = $2,514.58
Total of 1 Payments = $2,514.58
Total Interest = $14.58
What is simple intertest ?
Simple interest is calculated based on the principal of a loan or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accumulated.
Solution:
Principal value = $2500
Interest rate = 7%
Time = One month
Formula for simple interest calculation:
[tex]=\frac{Principalamount*rate *time}{100} \\=\frac{2500*7*(\frac{1}{12}) }{100}\\ =14.588[/tex]

The stores that will be in the sample are - 00, 02, 05, 08, 11, 14, 17, 20, 23.
What comprises the sample?
An analytical subset of a larger population is referred to as a sample in statistics. A sample are used in research so that it can be done quickly and with more manageable data. However, obtaining such a sample may be costly and time-consuming. Randomly generated samples do not have significant bias if they are large enough.
Stores in the Sample
Since it is given that the sample is made up of every third store, starting from the first retail store. The stores have been numbered systematically from 00 to 23. Since a systematic sampling is done, after picking the first store, the third store will be picked, that is, 02, and then 05, and so on till 23.
Thus, the following retail stores will be present in the sample,

1) You know that for any , neither sin nor cos can be greater than 1. How can you explain this using the unit circle definitions of sine and cosine? How can you explain it using the right triangle definitions of sine and cosine?
As a follow-up question, consider why it is important to have both the right triangle definitions of sine and cosine and the unit circle definitions of sine and cosine.
2) Can you give examples of situations that might be modeled with trigonometric functions? That is, can you give examples of phenomena that take on a series of values over and over again?
The trigonometric function gives the ratio of different sides of a right-angle triangle. The value of sine and cosine will be always less than a unit.
How to explain the trigonometry?In a unit circle, the radius of the circle represents the hypotenuse of the triangle. Since the hypotenuse is the largest side of the triangle, the ratio of the perpendicular to the hypotenuse and the base to the hypotenuse both will be less than the hypotenuse, therefore, 1. Hence, the value of sine and cosine will be always less than a unit.
In construction, we use trigonometry. For figuring areas of triangular shapes, similar to many concepts and phenomena in mathematics.

Which statement defines a translation?
OA A translation proportionally stretches or compresses an object based on a given scale factor.
OB. A translation moves points a specified distance along a line parallel to a specified line.
OC. In a translation, each point in the preimage and its corresponding point in the image are at equal distances from a given line.
Also, the line segment joining two such points is perpendicular to the given line.
OD. A translation is when an object moves in a circular arc around a point
the statement which defines a translation is option A that is "A translation proportionally stretches or compresses an object based on a given scale factor".
What is Translation ?
"Translation" moves points the same distance along lines that are parallel to each other.
Translation involves the initial object called the pre-image and the final object called the image. As you can see in the picture above, the rust-colored item represents the pre-image, and the blue item represents the image. Because of the arrow, we can tell the direction in which the image was moved. For other images, you may receive instructions on which image is the pre-image, or you may be asked to find the pre-image from the image.
Reflection, on the other hand, moves points along a specified line in such a way that the line bisects each line segment connecting corresponding pre-image points and image points.
There, the statement which defines a translation is option A that is "A translation proportionally stretches or compresses an object based on a given scale factor".

y=x The point F is the foot of the perpendicular from the point (1, 9) to the line y=x. Find the coordinates of F.
Answer: (5,5)
Step-by-step explanation:
The perpendicular to y=x has slope -1, and thus the equation of the perpendicular from (1,9) is [tex]y=-x+10[/tex].
Finding the point where they intersect, since both equations are set equal to y, we know that -x+10=x, and thus x=5.
If x=5, then y=5 as well.
So, F has coordinates (5,5).

If the polynomials p(x) = ax³+4x²+3x-4 and q(x) = x² - 4x + a, leave the same remainder when divided by (x-3), find value of a.
Steps pls
Answer:
a = -22/13.
Step-by-step explanation:
By the Remainder Theorem
p(3) = remainder when p(x) is divided by x-3.
q(3) is equal to the same remainder.
So we have:
p(3) = q(3) , so
a(3)^3 + 4(3)^2 + 3(3) - 4 = 3^2 - 4(3) + a
27a + 36 + 9 - 4 = 9 - 12 + a
27a - a = 9 - 12 - 36 - 9 + 4
26a = -12 - 36 + 4
26a = -44
a = -44/26
a = -22/13.

The length of the arc is 15.70 km
Arc length is more accurately described as the length along the perimeter of any circle or curve (arc). The arc length is the measurement of any distance along the curved path that forms the arc. Arc refers to a segment of a curve or the circumference of a circle. Each of them is shaped like a curve. An arc's length is more than the distance in a straight line between its endpoints (a chord).
The formula is given by
s = ϴ × r,
where
s is the arc length
r is the radius of the circle
θ is the central angle of the arc in radians
Given :- Radius = 10km
Angle = 90 ° = [tex]\pi[/tex]/2 radians (1 radian = 180°/[tex]\pi[/tex])

The approximate length of side AB is 14.0. The correct option is B. 14.0 units
Law of sinesFrom the question, we are to determine the measure of side AB
First, we will determine the measure of angle A
A + B + C = 180° (Sum of angles in a triangle)
A + 65° + 35° = 180°
A = 180° - 65° - 35°
A = 80°
Now, using the law of sines
c/sinC = a/sinA
c = AB
a = BC = 24
Thus,
c/sin35° = 24/sin80°
c = (24×sin35°)/sin80°
c = 13.978
c ≈ 14.0
