Step-by-step explanation:

if Neha is 4 years older than her son, so she will be sixteen.

The six trigonometric functions of an angle θ in a right triangle are sine (sin θ), cosine (cos θ), tangent (tan θ), cotangent (cot θ), secant (sec θ) and cosecant (csc θ).

To find these functions for a given angle θ, we need to know the length of the sides of a right triangle with angle θ.

Given that the point (-5,12) is on the terminal side of θ, we can apply the Pythagorean Theorem to find the length of the sides of the triangle. The Pythagorean Theorem states that a² + b² = c² where a and b represent the lengths of the sides of the triangle and c is the length of the hypotenuse. Using the point (-5,12), we can solve for c, which is 13.

Therefore, the sides of the triangle have lengths 5, 12, and 13. We can now use these lengths to calculate the trigonometric functions of θ.

sin θ = 12/13

cos θ = 5/13

tan θ = 12/5

cot θ = 5/12

sec θ = 13/5

csc θ = 13/12

Therefore, the six trigonometric functions of θ are sin θ = 12/13, cos θ = 5/13, tan θ = 12/5, cot θ = 5/12, sec θ = 13/5 and csc θ = 13/12.

The amount with simple interest is A = $ 16,380.92

Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.

Simple Interest = ( Principal Amount x Rate x Time Period ) / 100

Given data ,

Let the simple interest be represented as I

Now , the amount with simple interest = A

And , the principal P = $ 15,500

The rate of interest R = 6.2 %

The number of months n = 11 months

So , the number of years T = 11/12 years

Simple Interest I = ( Principal Amount x Rate x Time Period ) / 100

Substituting the values in the equation , we get

Simple Interest I = ( 15,500 x 6.2 x ( 11/12 ) ) / 100

On simplifying the equation , we get

Simple Interest I = $ 16,380.916987

Simple Interest I = $ 16,380.92

Hence , the future value if $ 16,380.92

In  trapezoid ABCD we have AB parallel to DC, E as the midpoint of BC

AB/DC = 5

given that

In American and Canadian English, a quadrilateral having at least one pair of parallel sides is referred to as a trapezoid (/traepzd/). It is referred to as a trapezium in British and other varieties of English (/trpizim/).

In Euclidean geometry, a trapezoid is a convex quadrilateral by definition. The bases of the trapezoid are the parallel sides. If the remaining two sides are parallel, they are referred to as the legs (or lateral sides); if not, the trapezoid is a parallelogram, and there are two pairs of bases. A scalene trapezoid is one that lacks equal-sized sides.

In trapezoid ABCD we have AB parallel to DC

E as the midpoint of BC

F as the midpoint of DA.

The area of ABEF is twice the area of FECD.

AB+EF/2 = 2(DC+EF/2)

AB+EF/2 = DC+EF

AB+EF = 2DC+2EF

EF is the midline between AB and DC

Given: x = 1+(y−2)², x=2

We have to find the volume of the solid obtained by rotating the region bounded by the given curves about the x-axis.

Rotating with the cylinder method about the x-axis means it must be a dy integral. The given parabola equation is already solved for x. Find the intersections:

2 =  1 + (y−2)²

0 = (y -1)(y-3)

y = 1, 3

We will integrate from

y = 1 to 3

The radius of each cylinder will be r=y and the height will be (greater minus lesser, i.e. right minus left).

h = 2 - (1 + (y-2)²)

h = 1 - y² + 4y -4

Using the trigonometric ratios for the angle A-cosθ= Base/ Hypotenuse =11.8726

What is trigonometric?

Trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). These six trigonometric functions in relation to a right triangle are displayed in the figure.

For example, the triangle contains an angle A, and the ratio of the side opposite to A and the side opposite to the right angle (the hypotenuse) is called the sine of A, or sin A; the other trigonometry functions are defined similarly. These functions are properties of the angle A independent of the size of the triangle, and calculated values were tabulated for many angles before computers made trigonometry tables obsolete. Trigonometric functions are used in obtaining unknown angles and distances from known or measured angles in geometric figures.

Here, if we consider the ∠A=θ, then AB is the base, BC is the perpendicular, and AC is the hypotenuse.

And it is given that, ∠A=θ=32°,AB=x, and C=14 units.

The area of the region is equal to the area of the septagon minus the area of the circumscribing circle. The area of the septagon = 7 x (5^2 x (1 + sqrt(3))/4). The area of the circumscribing circle = pi x (5^2/2).

The area of the region between the septagon and its circumscribing circle can be found by subtracting the area of the circumscribing circle from the area of the septagon. The side length of the septagon is 5 inches. The area of the septagon can be calculated using the formula A = 7 x (5^2 x (1 + sqrt(3))/4). This is equal to 58.82 inches squared. The area of the circumscribing circle can be calculated using the formula A = pi x (5^2/2). This is equal to 78.54 inches squared.

Answer:

Step-by-step explanation:

To find the value of 12 – 4 + 2h when h = 3, we need to substitute the value of h into the expression and simplify.

When h = 3, we can substitute this value into the expression:

12 – 4 + 2h = 12 - 4 + 2*3 = 12 - 4 + 6 = 12 - 4 + 6 = 8 + 6 = 14

So the value of 12 – 4 + 2h when h = 3 is 14.

Answer:

12 - 4 + 2h = 14

Step-by-step explanation:

Given expression,

→ 12 - 4 + 2h

Now we have to use,

→ h = 3

Let's simplify the expression,

→ 12 - 4 + 2h

→ 12 - 4 + 2(3)

→ 12 - 4 + 6

→ 8 + 6

→ 14 => {final value}

Hence, required value is 14.

Answer: 1,500+7=2,200 Y=700 2.

Answer:

= (-3)/2

Step-by-step explanation:

Compute the slope of the line through the following points:

p_1 = (-2, 6) and p_2 = (-4, 9)

The slope of the line through (x_1, y_1) and (x_2, y_2) is:

(y_2 - y_1)/(x_2 - x_1)

Substitute (x_1, y_1) = (-2, 6) and (x_2, y_2) = (-4, 9):

= (9 - 6)/(-4 - -2)

9 - 6 = 3:

= 3/(-4 - -2)

-(-2) = 2:

= 3/(-4 + 2)

-4 + 2 = -2:

= 3/(-2)

Multiply numerator and denominator of 3/(-2) by -1:

Answer:  = (-3)/2

if N < 10 then the count of numbers will be N , if N / 10 < 10 then 9 , if

N / 100 < 10 then 9 + N – 99 , if N / 1000 < 10 then 9 + 900 , if N / 10000 < 10 then 909 + N – 9999.
