If cosA = 24/25 tanB = 4/3 and angles A and B are in Quadrant I. The value of tan(A-B) is -23/33.

We can start by using the identity: tan(A - B) = (tan A - tan B)/(1 + tan A tan B)

From the given information, we have:

cos A = 24/25, which means sin A = sqrt(1 - cos^2 A) = 7/25 (since A is in Quadrant I)

tan B = 4/3, which means sin B = 4/sqrt(4^2 + 3^2) = 4/5 and cos B = 3/sqrt(4^2 + 3^2) = 3/5

Now, we can use the definitions of sine and cosine to find tan A:

tan A = sin A / cos A = (7/25)/(24/25) = 7/24

Substituting the values we have found into the formula for tan(A - B), we get:

tan(A - B) = (tan A - tan B)/(1 + tan A tan B)

= [(7/24) - (4/3)]/[1 + (7/24)(4/3)]

= (-13/72)/(25/72)

= -13/25

Therefore, tan(A - B) = -13/25.

Answer:

roughly 12.56 units

Step-by-step explanation:

Since the perimeter of a circle is 2*pi*r, we can divide it by two or multiply by half in order to find the perimeter of a semicircle

half of the diameter is the radius, so 8/2 =4, r=4

Plug in what we know...

C=2*pi*4

Solve

2*3.14*4

25.12

divide by 2

25.12/2=12.56

12.56 units is the perimeter

Answer:

Approx. 20.566 units

Step-by-step explanation:

Find the circumference of the whole circle first by doing:

C = 2πr

r = 4 (8 divided by 2)

C ≈ 25.133

Then divide that by two because a semi-circle is half a circle:

12.566

Then add 8 (diameter) to that number for the open side.

If you plug in the answers it will give you 9x6= 54 which is wrong and 9x7=63 and 9x9=81 but 9x8=72.

Answer:

C   length = 8

Step-by-step explanation:

Area of Rectangle = lw

A = lw    Substitute l = (2x + 4) ; w = 9

72 = (2x + 4)9

72 = 18x + 36

36 =        -36

36 = 18x

36/18 = x

 2 = x

 Substitute into l = 2x + 4 ; l = 2(2) + 4; l = 4 + 4 ; l = 8

Let's begin by simplifying each of the terms in the expression on the left-hand side of the equation:

(x^m * x^n)^(m-n) = x^(m-n)*(m-n)

(x^p * x^(-n))^(n+p) = x^(n+p)*(p-n)

(x^p * x^(-m))^(p+m) = x^(p+m)*(p-m)

Now, let's substitute the given equation p^2 - n^2 = 1 into these expressions:

x^(m-n)*(p^2-n^2) = x^(m-n)

x^(n+p)*(p^2-n^2) = x^(n+p)

x^(p+m)*(p^2-n^2) = x^(p+m)

Simplifying each of these expressions using the given equation, we get:

x^(m-n) = x^(m-n)

x^(n+p) = x^(n+p)

x^(p+m) = x^(p+m)

Therefore, the left-hand side of the equation simplifies to:

x^(m-n) * x^(n+p) * x^(p+m) = x^(m-n + n+p + p+m) = x^(2m) = x^2^(m-n + n+p + p+m)

Thus, we have proved that:

(x^m * x^n)^(m-n) * (x^p * x^(-n))^(n+p) * (x^p * x^(-m))^(p+m) = x^2

which is the same as the given equation.

Answer:

C=2(3.14)×(5)

C=31.4cm

The circumference of circle is 31.4 cm

"It is the distance around the perimeter of a circle."

"C = 2 × π × r,

where r is the radius of the circle."

For given question,

We have been given the radius of a circle.

r = 5 cm

We need to find the circumference of circle.

Using the formula for circumference of circle,

⇒ C = 2 × π × r

We need to use π = 3.14

⇒ C = 2 × 3.14 × 5

⇒ C = 2 × 5 × 3.14                        ...............(since  a × (b × c) = (a × b) × c)

⇒ C = 10 × 3.14

⇒ C = 31.4 cm

This means, the circumference of circle having radius r = 5 cm

is C = 31.4 cm

Therefore, the circumference of circle is 31.4 cm

Answer:

They would be perpendicular to each other.

One would have a slope of 0 (horizontal line) and the other would have an undefined slope (vertical line)

Step-by-step explanation:

Poppy's sister used approximately 3.14 inches more wire per wall hanging than Poppy.

To find the amount of wire used by both Poppy and her sister, we'll calculate the circumference of their respective wall hangings using the formula:

C = 2πr

Since the diameter is twice the radius, we can find her sister's radius as follows:

Poppy's radius = 6.25 inches

Poppy's diameter = 2 * 6.25 = 12.5 inches

Sister's diameter = Poppy's diameter + 1 = 12.5 + 1 = 13.5 inches

Sister's radius = 13.5 / 2 = 6.75 inches

Now, we'll calculate the circumferences using the given value for π:

Poppy's circumference = 2 x 3.14 x 6.25 ≈ 39.25 inches

Sister's circumference = 2 x 3.14 x 6.75 ≈ 42.39 inches

Difference = Sister's circumference - Poppy's circumference

Difference = 42.39 - 39.25 = 3.14 inches

Answer:

y=-2

Step-by-step explanation:

The line is y = 2x-2, so when x=0 y= -2

Therefore, the correct answer is B) The series diverges, and the terms of the series have limit o.

The integral test is a powerful tool used to determine whether an infinite series converges or diverges. The integral test states that if an infinite series has a non-negative and decreasing term, then the series is convergent if and only if the corresponding integral is convergent. In the case of the series ∑n=2[infinity]1nlnn, we can apply the integral test by considering the function f(x) = 1/xlnx. This function is decreasing and positive for all x > 2. Therefore, we can integrate f(x) from 2 to infinity to obtain the integral ∫2[infinity]1/xlnx dx. Evaluating this integral, we get ln(lnx)|2[infinity], which diverges. Since the integral diverges, we can conclude that the series ∑n=2[infinity]1nlnn also diverges.

Pythagorean theorem tells us how the side lengths of right triangles are related.

The Pythagorean theorem, also known as the Pythagorean identity, states that the sum of the squares of the lengths of the two sides forming the right angle is equal to the square of the length of the hypotenuse in any right triangle (the side opposite the right angle). In other words, the Pythagorean theorem can be used to calculate the length of the hypotenuse given the lengths of the two sides of a right triangle.

This relationship can be written as the equation:

\(a^2 + b^2 = c^2\)

where a and b are the lengths of the legs, and c is the length of the hypotenuse. The Pythagorean Theorem is named after the ancient Greek mathematician Pythagoras, who is credited with its discovery.

The person is approximately 4.37 km away from where she started.

To determine the distance from where the person started, we can use the Pythagorean theorem to calculate the straight-line distance between the starting point and the final position.

Given:

Distance traveled southwest = 1.75 km

Distance traveled east = 3.95 km

Using the Pythagorean theorem:

Distance from where she started = sqrt((1.75 km)^2 + (3.95 km)^2)

Distance from where she started ≈ sqrt(3.06 km^2 + 15.6 km^2)

Distance from where she started ≈ sqrt(18.66 km^2)

Distance from where she started ≈ 4.32 km

Therefore, the person is approximately 4.37 km away from where she started.

Explanation in more than 100 words:

To calculate the distance from where the person started, we can visualize their movements as a right-angled triangle. The southwest direction can be considered as the diagonal side of the triangle, and the east direction can be considered as the adjacent side of the triangle. The distance from where she started is the hypotenuse of this triangle.

Using the Pythagorean theorem, we can calculate the magnitude of the hypotenuse (distance from where she started) by squaring the lengths of the other two sides and taking the square root of their sum.

In this case, the distance traveled southwest is 1.75 km, and the distance traveled east is 3.95 km. We can square these values:

(1.75 km)^2 = 3.06 km^2

(3.95 km)^2 = 15.6 km^2

Adding these squared values:

3.06 km^2 + 15.6 km^2 = 18.66 km^2

Taking the square root of 18.66 km^2, we find:

sqrt(18.66 km^2) ≈ 4.32 km

Therefore, the person is approximately 4.37 km away from where she started. This means that after making the two turns and traveling a total distance of 5.7 km (1.75 km southwest + 3.95 km east), she is located approximately 4.37 km in a straight line from her starting point.

Yes, the figure shown in the xy-coordinate plane is a parallelogram because side OP is parallel to side TS and side OT is parallel to side PS

In order for any quadrilateral to be considered a parallelogram, two pairs of its parallel sides must be equal (congruent). Therefore, we would determine the slope of each side by using this mathematical equation:

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

For side OP, the slope is given by:

Slope (m) = (b - 0)/(a - 0)

Slope (m) = b/a.

For side TS, the slope is given by:

Slope (m) = (0 - )/(c - (a + c))

Slope (m) = -b/-a = b/a

Therefore, side OP is parallel to side TS.

For side OT, the slope is given by:

Slope (m) = (0 - 0)/(c - 0)

Slope (m) = 0.

For side PS, the slope is given by:

Slope (m) = (b - b)/((a + c) - c)
