The slope of the line passing through the points (10) 2, and (14), is -9/-13.
What is slope?A line's steepness and direction are measured by the line's slope.
Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all
Any two different points on a line can be used to calculate the slope of any line.
A line's slope is determine by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.
Two locations located on a straight line can be used to determine a line's slope. We can use the slope of line formula if we know the two spots' coordinates. These two points' coordinates should be-
P1 = (x1, y1) and P2 = (x2, y2)
Hence, The slope of the line passing through the points (10) 2, and (14), is -9/-13.

Which is true about the digit 2 in each number?
The true statement is that 2 in 142 represents a greater value than 2 in 124 because 142 > 124.
How to identify the place value of a digit in a number?The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol. The place values on the left ofthe decimal point start as ones, tens, hundreds, and so on.
The place value on the right of the decimal point starts from a point and goes to right as tenths, hundredths, and so on.
We are given that encore or points for an NBA Team are usually as whole numbers.
For example, 1, 2, 3, 4, e.t.c. points of an NBA Team are not in decimals or fractions.

(quickly!) What is the value of x
The value of x for the given triangle is x = 86°.
What is triangle?
Three edges and three vertices make up a triangle, which is a polygon. It is among the fundamental shapes in geometry. Triangle ABC refers to a triangle with the vertices A, B, and C. In Euclidean geometry, any three points that are not collinear determine a singular triangle and a singular plane at the same time.
From the given triangle we have to find the value of x.
By triangle's property.
(x - 45)° + (x + 3)° = (x + 44)°
2x - 42 = x + 44
2x -x = 44 + 42
x = 86°
Hence, the value of x for the given triangle is x = 86°.

What is sum of angles of a triangle?
A triangle's total angles equal the straight angle (180 degrees, radians, two right angles, or a half-turn) in a Euclidean space. Three angles, one at each vertex and bounded by two neighbouring sides, make up a triangle.
For a very long period, it was unknown if there were any alternative geometries for which the total is different. During the 19th century, this issue had a particularly significant impact on mathematics. Ultimately, it was determined that the response was correct: in other geometries, this total can be higher or smaller, but it must then depend on the triangle. Its deviation from 180° represents an instance of an angular defect and is a crucial distinction for geometric systems.
From the fig.
we know,
e=37
b= 143 (vertically opposite angle)
143 + a = 180 (Linear pair)
a = 180 - 143
a = 37
e = 37
So, c = 37 (Vertically opposite angle)
c + d + 85 = 180 (Sum of angles on straight line)
37 + d + 85 = 180
d = 180 - 122
d = 58
e + 90 + f = 180 (Sum of all angles of a triangle)
37 + 90 + f = 180
f = 180 - 127
f = 53
g = 48 (if two sides are equal , then the two angles opposite to the equal
sides will also be equal.)
48 + 48 + h = 180 (Sum of angles of a triangle)
h = 180 - 96
h = 94
h+ k = 180 (Linear pair)
94 + k = 180
k = 180 - 94
k = 96
d + k + m = 180 (Sum of angles of a triangle)
58 + 96 + m = 180
m = 180 - 154
m = 26
26 + 85 + p = 180 (Sum of angles of a triangle)
p = 180 - 111
p = 69
p + r = 180 (Linear pair)
r = 180 - 69
r = 111
p = s (corresponding angles)
s = 69
Hence all angles are:

$2, 900 is invested in an account earning 6.1% interest (APR), compounded quarterly. Write a function showing the value of the account after t years, where the annual growth rate can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage of growth per year (APY), to the nearest hundredth of a percent.
Answer: The value of the account after t years can be found using the formula:
Value = 2900 * (1 + 0.0061/4)^(4t)
The annual growth rate, or APR, is 6.1%. When this rate is compounded quarterly, the effective annual growth rate, or APY, is 6.17%, which is the nearest hundredth of a percent.
Therefore, the function showing the value of the account after t years is:
Value = 2900 * (1 + 0.0061/4)^(4t)
And the annual growth rate, or APY, is 6.17%.

in an isosceles triangle the perimeter is 8 more than two times one of the legs if the perimeter is 28 find the length of the base
Answer:
base = 8
Step-by-step explanation:
In an isosceles triangle, the legs are equal.
P = 28 = 2L + 8
2L + 8 = 28
2L = 20
L = 20/2 = 10 (length of each leg)
P = 2L + b (sum of the lengths of the 2 legs and the base)
28 = 2(10) + b
b = 28 - 20 = 8

f f(x)=tan(2x), what is the absolute difference between f(5.4) and T2(5.4), if the second degree Taylor polynomial is centered at x = 5?
Round your answer to 3 places.
The absolute difference rounded to three decimal places is 2.674.
What is polynomial?
An expression that consists of variables, constants, and exponents and is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.
Given: f(x) = tan(2x)
Then f(5.4) = tan(2 x 5.4) = tan(10.8) = tan(54/5)
The second degree Taylor polynomial centered at x = 5 is given by,
T2(x) = Σ(n = 0, 2) f^n(5)/5!(x - 5)^n
Now,
f°(x) = f(x) = tan(2x)
f(5) = tan(2 x 5) = tan(10)
f'(x) = d/dx(tan(2x))
f'(x) = 2 sec^2x = 2( 1 + tan^2(x))
f'(5) = 2(1 + tan^2(10))
f"(x) = d/dx[2(1 + tan^2(2x)]
f"(x) = 0 + 2(2tan(2x)(2sec^2(2x))
f"(x) = 8 tan(2x)(1 + tan^2(2x))
f"(5) = 8 tan(10)(1 + tan^2(10)
Then
[tex]T_2(x) = \frac{tan(10)}{0!}(x - 5)^0 + \frac{2 + 2tan^210}{1!}(x - 5)^1 + \frac{8(tan(10)(1+tan^2(10)}{2!}(x - 5)^2 \\T_2(5.4) = tan(10) + 2(1 + tan^2(10)) (5.4 - 9) +4tan(10)(1 + tan^2(10)(5.4 - 5)^2\\T_2(5.4) = \frac{16}{25} tan^310 + \frac{4}{5}tan^2(10) + \frac{41}{25} tan(10) + \frac{4}{5}[/tex]
The absolute difference is,
[tex]|f(5.4) - T_2(5.4)| = 2.673745[/tex]
|f(5.4) - T2(5.4)| ≈ 2.674

A.
12.8 kilometers per hour
B.
26 kilometers per hour
C.
27.3 kilometers per hour
John's average speed for the whole race would be; 12.8 kilometers per hour
How to calculate the average speed?The first part of the race was 14 km long, and he completed it in 1 hour.
Now, formula for speed is;
Speed = distance/time
Thus, John's speed in the first part of the race would be;
14/1 = 14km/hr
The second part was 18 km long, and he completed this part in an hour and a half. This means that his speed in the second part of the race is;
18/1.5 = 12km/hr
Average speed = Total distance/total time
Total distance for both parts of the race is;
14 + 18 = 32km
Total time for the race is;

The probability of rain on Monday is .1. The probability of rain on Tuesday is .8. What is the probability of rain on both Monday and Tuesday?
Answer:
The probability of rain on both Monday and Tuesday is .08, or approximately 8%.
Step-by-step explanation:
The probability of an event occurring on two separate days (such as rain on Monday and Tuesday) is calculated by multiplying the probabilities of the two events occurring separately. In this case, the probability of rain on both Monday and Tuesday is given by:
Probability of rain on Monday * Probability of rain on Tuesday = .1 * .8 = .08
Therefore, the probability of rain on both Monday and Tuesday is .08, or approximately 8%.
It's important to note that this probability assumes that the likelihood of rain on each day is independent of the other day. In other words, the probability of rain on Tuesday does not depend on whether or not it rained on Monday. If this is not the case, the probability of rain on both days may be different.

What is the equation of a line?
An algebraic way to represent a collection of points that together make a line in a coordinate system is called the equation of a line. An algebraic equation, commonly known as the equation of a line, can be created using the various points that together make up a line in the coordinate axis as a collection of variables (x, y). It is possible to determine whether a specific point lies on a line by utilising the equation of a line.

Given, two points are (-3,-15/2) and(1,-3/2).
[tex](x_{1} ,y_{1} )[/tex] = (-3,-15/2) and [tex](x_{2},y_{2})[/tex] = (1,-3/2).
So, The equation of line passing through (-3,-15/2) and (1,-3/2) is given by
or, [tex]\frac{y+\frac{15}{2} }{x+3 } = \frac{-\frac{3}{2} +\frac{15}{2} }{1 +3 }[/tex]
