The area of each square below is 1 square unit. What is the area of the striped region? if you get it first brainly

Answer:

rffrefr

Step-by-step explanation:

Answer:

9x^3 y^5

Step-by-step explanation:

Since the formula to finding area is (L*W = A), we first have to find the width.

Width: 3x^3 y^5 times 2 = 6x^3 y^5

Then we add them. So, 3x^3 y^5 + 6x^3 y^5 = 9x^3 y^5

Opening Exercise

The original triangle, labeled A, has been reflected across the first line, resulting in the image labeled B. Reflect the image across the second line. Carlos looked at the image of the reflection across the second line and said, “That’s not the image of triangle A after two reflections; that’s the image of triangle A after a rotation!” Do you agree? Why or why not?

Discussion

When you reflect a figure across a line, the original figure and its image share a line of symmetry, which we have called the line of reflection. When you reflect a figure across a line and then reflect the image across a line that intersects the first line, your final image is a rotation of the original figure. The center of rotation is the point at which the two lines of reflection intersect. The angle of rotation is determined by connecting the center of rotation to a pair of corresponding vertices on the original figure and the final image. The figure above is a 210° rotation (or 150° clockwise rotation).

Exploratory Challenge

Line of symmetry of a figure: This is an isosceles triangle. By definition, an isosceles triangle has at least two congruent sides. A line of symmetry of the triangle can be drawn from the top vertex to the midpoint of the base, decomposing the original triangle into two congruent right triangles. This line of symmetry can be thought of as a reflection across itself that takes the isosceles triangle to itself. Every point of the triangle on one side of the line of symmetry has a corresponding point on the triangle on the other side of the line of symmetry, given by reflecting the point across the line. In particular, the line of symmetry is equidistant from all corresponding pairs of points. Another way of thinking about line symmetry is that a figure has line symmetry if there exists a line (or lines) such that the image of the figure when reflected over the line is itself.

Does every figure have a line of symmetry?

To find the exact value of (7π/6) using the unit circle, locate the angle (π/6) on the unit circle in the second quadrant, determine the coordinates, and adjust the y-coordinate to be negative. The final answer is (√3/2, -1/2). This answer is obtained by understanding the reference angle and using the coordinates of the point where the angle intersects the unit circle.

To find the exact value of (7π/6) using the unit circle, follow these steps:

1. Start by understanding the reference angle. The reference angle for (7π/6) is (π/6).

2. Locate the angle (π/6) on the unit circle. This angle lies in the second quadrant.

3. Determine the coordinates of the point where the angle intersects the unit circle. For (π/6), the x-coordinate is √3/2 and the y-coordinate is 1/2.

4. Since (7π/6) lies in the second quadrant, the x-coordinate will remain the same, but the y-coordinate will be negative. Therefore, the coordinates for (7π/6) are (√3/2, -1/2).

5. The exact value of (7π/6) is (√3/2, -1/2).

Step-by-step explanation:

The yield Mary Blake makes from investing in the stock is about 5.24%, and the yield from the bonds is 11.5%, while the value of the amount the bond yields is $106.375

          \({}\)           Yield

Stock \({}\)           5.24%

Bond \({}\)           11.5%

An investment is the an input of (financial) capital into the acquisition of assets that will generate future revenue.

The amount at which the stock Mary Blake is looking at is trading = $66.75

The annual dividend of the stock = $3.50

The amount at which the bond is trading = 92.50% of par

The annual interest rate from the bond = 11.5%

Mary Blake's percentage yield from investing in the stock can be found as follows;

Yield percentage = (3.5/66.75) × 100 ≈ 5.24%

The percentage yield from the bond as indicated in the question is 11.5%

The yield amount from the bond is found as follows;

Amount of the bond = $1000 × 92.50 = $925.0

The yield amount = 11.5% × $925.0 = $106.375

Answer:

slope = -3

Step-by-step explanation:

The function f(x) = -3x + 125 is a linear function in slope-intercept form y = mx + b.  The slope, m, is -3.  This means that for every increase of 1°C, 3 less fish are caught.  

By using the fact that the sum of the internal angles must be 180°, we will see that b = 119°

Here we need to use the fact that the sum of all the internal angles of a triangle is always equal to 180°.

Here the internal angles are 30°, 31° and b, then we can write the linear equation:

30° + 31° + b = 180°

Solving this for b, we will get:

b = 180° - 30° - 31°

b = 119°

That is the value of b.

\(\bold{\text{Answer: b.}\quad \dfrac{y^2}{100}+\dfrac{x^2}{49}=1}\)

Step-by-step explanation:

The ellipse is vertical so y has the biggest radius.

Major axis (y) = 20 so the y-radius is 20/2 = 10

Minor axis (x) = 14 so the x-radius is 14/2 = 7

The equation of an ellipse is:   \(\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1\)   where

Given: a = 7, b = 10

Assume: (h, k) = (0, 0)

\(\dfrac{(x-0)^2}{7^2}+\dfrac{(y-0)^2}{10^2}=1\\\\\\\dfrac{x^2}{49}+\dfrac{y^2}{100}=1\\\\\\\longrightarrow \dfrac{y^2}{100}+\dfrac{x^2}{49}=1\)

To find the slope of the line that passes through points (0, 3) and (4, -2), we can use the formula for the slope of a line:

We have then:

(0, 3) ---> x1 = 0, y1 = 3

(4, -2) --->x2 = 4, y2 = -2

Therefore:

Then, the slope of the line that passes through points (0, 3) and (4, -2) is m = -5/4.

For the length of the punt, we equate the expression to zero f(x) = 0.

Given f(x) is the height (in feet) and x is the horizontal distance (in feet) from the point at which the ball is punted.

Horizontal distance means the distance between two points measured at a zero percent slope.

(-16/1225)x^2 + (7/5)x + 2.5 = 0

\(\left(\frac{-16}{1225}\right)x^2+\left(\frac{7}{5}\right)x+2.5=0\)

\(\frac{-16}{1225}x^2\cdot \:10+\frac{7}{5}x\cdot \:10+2.5\cdot \:10=0\cdot \:10\)

\(-\frac{32}{245}x^2+14x+25=0\)

\(-\frac{32}{245}x^2\cdot \:245+14x\cdot \:245+25\cdot \:245=0\cdot \:245\)

\(-32x^2+3430x+6125=0\)

\(x_{1,\:2}=\frac{-3430\pm \sqrt{3430^2-4\left(-32\right)\cdot \:6125}}{2\left(-32\right)}\)

\(x_{1,\:2}=\frac{-3430\pm \:70\sqrt{2561}}{2\left(-32\right)}\)

\(x_1=\frac{-3430+70\sqrt{2561}}{2\left(-32\right)},\:x_2=\frac{-3430-70\sqrt{2561}}{2\left(-32\right)}\)

\(x=-\frac{35\left(\sqrt{2561}-49\right)}{32},\:x=\frac{35\left(49+\sqrt{2561}\right)}{32}\)
