I need to write an equation for the following, please help!!

slope = 2; y-intercept is (0,5)

Answer: arc BC is 60

Step-by-step explanation: if AC is the diameter and AWB is 120 degrees,

diameter= half a circle (180)

180-120

=60

hope this helped!! (sorry if its wrong)

Answer:

\(\overset\frown{BC}=60^{\circ}\)

Step-by-step explanation:

The diameter of a circle is a straight line that passes through the center of the circle and whose endpoints lie on the circle.

Since angles on a straight line sum to 180°, and AC is the diameter of circle W, then:

\(m \angle AWB + m \angle BWC = 180^{\circ}\)

Given the measure of angle AWB is 120°:

\(\begin{aligned} m \angle AWB + m \angle BWC &= 180^{\circ}\\ 120^{\circ} + m \angle BWC &= 180^{\circ}\\ m \angle BWC &= 180^{\circ}-120^{\circ}\\m \angle BWC &= 60^{\circ}\end{aligned}\)

The measure of an intercepted arc is equal to the measure of its corresponding central angle. Therefore:

\(\overset\frown{BC}=m \angle BWC=60^{\circ}\)

Therefore, the measure of arc BC is 60°.

Answer:

7.6 ft

Step-by-step explanation:

The volume of a sphere is

V = 4/3 pi r^3

A hemisphere is 1/2 of  a sphere

V = 1/2 (4/3 pi r^3)

V = 2/3 pi r^3

920 = 2/3 pi r^3

Multiply each side by 3/2

920 * 3/2 = 3/2 * 2/3 pi r^3

1380 = pi r^3

Divide each side by pi

1380/pi = pi r^3 / pi

1380/ pi = r^3

Using pi as 3.14

1380/3.14 = r^3

439.4904459= r^3

Taking the cube root of each side

(439.4904459)^(1/3)= r^3^(1/3)

7.602967711=r

To the nearest tenth

7.6 = r

radius=7.6ft

Answer:

Solution given:

radius [r]=?

Volume of hemisphere=920ft³

⅔*πr³=920

r³=920*3/(2π)

r³=439.267

Rate of change means how much does the number of snowflakes go up each time (on a different question you might find the number goes down each time)

"Initial value" means whatthe number if snowflakes at step zero. We have to work backwards to find that number. For the equation, fill in the rate in front of the x (we use m for that number) and add in the initial value (b) in the format y=mx+b .

The Taylor polynomial T3(x) for the function f centered at the number a is expressed with the equation:

T₃(x) = (1/4) + (-1/16)(x - 4) + (1/32)(x - 4)² + (-3/128)(x - 4)³

From the information given, we have that;

If a = 4, we have;

To find the Taylor polynomial T₃(x) for the function f(x) = 1/x centered at a = 4,

x = a = 4:

f(4) = 1/4

The first derivatives

f'(x) = -1/x²

f'(4) = -1/(4²)

Find the square value, we get;

f'(4) = -1/16

The second derivative is expressed as;

f''(x) = 2/x³

f''(4) = 2/(4³)

Find the cube value

f''(4) = 2/64

f''(4)  = 1/32

For the third derivative, we get;

f'''(x) = -6/x⁴

f'''(4) = -6/(4⁴)

Find the quadruple

f'''(4)  = -6/256

f'''(4) = -3/128

The Taylor polynomial T₃(x) centered at a = 4 is expressed as;

T₃(x) = (1/4) + (-1/16) (x - 4) + (1/32 )(x - 4)² + (-3/128) (x - 4)³

The estimate for the area under the graph of f(x) = 7x from x = 1 to x = 5 using 4 approximating rectangles and right endpoints is 84. The estimate using left endpoints is 70.

To estimate the area under the graph using rectangles, we divide the interval [1, 5] into smaller subintervals. In this case, we have 4 rectangles, each with a width of 1. The right endpoint of each subinterval is used as the height of the rectangle. We can also use the right Riemann sum approach.

Adding up the areas of the rectangles, we get 14 + 21 + 28 + 35 = 98.

However, since the rectangles extend beyond the actual area, we need to subtract the excess.

The excess is equal to the area of the rightmost rectangle that extends beyond the graph, which has a width of 1 and a height of f(6) = 7(6) = 42.

Subtracting this excess, we get an estimate of 98 - 42 = 56.

Dividing this estimate by 4, we obtain 14, which is the area of each rectangle.

Hence, the estimate for the area under the graph using right endpoints is 4 * 14 = 56.

Similarly, we can calculate the estimate using left endpoints by using the left endpoint of each subinterval as the height of the rectangle.

In this case, the estimate is 4 * 14 = 56.

Therefore, the estimate using left endpoints is 56.

The terms syllabic, melismatic, and neumatic are all related to the number of notes in relation to each syllable of a text. Syllabic means that each syllable of the text is sung to one note.

This is the simplest type of setting for text to music. In contrast, melismatic means that each syllable of the text is sung to many notes, creating a more intricate and ornamental melody. Neumatic is somewhere in between syllabic and melismatic, where each syllable is sung to a few notes, but not as many as in a melismatic setting.

In a painting class, students will pick sets that show combinations of primary colors.

Primary colors are the basic colors from which all other colors can be created. In traditional color theory, the primary colors are red, blue, and yellow. When these colors are mixed together, they can produce a wide range of secondary and tertiary colors. To create a set of primary colors, students would choose combinations of red, blue, and yellow. For example, they might pick a set that includes pure red, pure blue, and pure yellow, allowing them to mix various shades and hues by combining these primary colors. By experimenting with different proportions and mixing techniques, students can create a vast array of colors using just the primary colors. Understanding the mixing of primary colors is fundamental in art, as it allows artists to achieve the desired color palette and effectively express their creative vision. By learning how primary colors interact and blend, students can develop a strong foundation in color theory and expand their artistic possibilities.

a. The conditional probability function of X given Y=2 is f(x|2) is 0.55 for x = 1, 2, 3, and f(x|2) = 0 for all other values of x. b. Cov(X,Y) = 2.43 - (3.13)(3.77) = -0.41. c. f(x,y) is not equal to fX(x)fY(y) for some values of x and y, X and Y are dependent.

(a) The conditional probability function of X given Y=y is f(x|y) = f(x,y) / fY(y). The conditional probability function of Y given X=x is f(y|x) = f(x,y) / fX(x).

i. The conditional probability function of X given Y=2 is f(x|2) = 0.12 / 0.22 = 0.55 for x = 1, 2, 3, and f(x|2) = 0 for all other values of x.

ii. The conditional probability function of Y given X=3 is f(y|3) = 0.03 / 0.07 = 0.43 for y = 1, 2, 3, and f(y|3) = 0 for all other values of y.

(b) The covariance between X and Y is given by Cov(X,Y) = E(XY) - E(X)E(Y), where E(XY) is the expected value of the product of X and Y, and E(X) and E(Y) are the expected values of X and Y, respectively. Using the joint probability function, we have E(XY) = 1(0.08) + 2(0.09) + 3(0.10) + 4(0.05) + 6(0.08) + 9(0.05) = 2.43, E(X) = 1(0.19) + 2(0.22) + 3(0.25) + 4(0.10) + 6(0.14) + 9(0.10) = 3.13, and E(Y) = 1(0.15) + 2(0.22) + 3(0.28) + 4(0.07) + 6(0.17) + 9(0.11) = 3.77. Therefore, Cov(X,Y) = 2.43 - (3.13)(3.77) = -0.41.

(c) X and Y are not independent because f(x,y) = 0.08 for x=1 and y=1, while fX(1)fY(1) = 0.19(0.15) = 0.0285. Since f(x,y) is not equal to fX(x)fY(y) for some values of x and y, X and Y are dependent.

Answer:

170 kg. of parsnips are left

Step-by-step explanation:

Given:

850 kg. of parsnips

30 % to the local market

50 % to a local supermarket

Solution:

First, add the two percentages.

30 + 50 = 80%

That means 80 % of parsnips mass go to the markets.

Now let's find the mass of delivered parsnips.

Change 80% to decimal form.

80% = 0.8

Now multiply it by 850 kg.

850 x 0.8 = 680

The delivered parsnips mass is 680 kg.

Now to find the mass of parsnips left, subtract 680 to 850

850 - 680 = 170 kg.

170kg. of parsnips are left.

Step-by-step explanation:

5(r + 9) - 2(1 - r) = 1

5r + 45 - 2 + 2r = 1

7r + 43 = 1

7r = -42

r = -6.

Answer:

r = -6

Step-by-step explanation:

Given equation,

→ 5(r + 9) - 2(1 - r) = 1

Now the value of r will be,

→ 5(r + 9) - 2(1 - r) = 1

→ 5r + 45 - 2 + 2r = 1

→ 5r + 2r + 43 = 1

→ 7r = 1 - 43

→ 7r = -42

→ r = -42/7

→ [ r = -6 ]

Hence, the value of r is -6.

Step-by-step explanation:

The scale factor of figure A to figure B is 5/2

A scale factor can be defined as the ratio of the scale difference between  a given original shape and a new shape.

It is seen as a number from which the size of a dimensional shape or figure can be transformed with respect to its original size or magnitude.

It is also described as the ratio between corresponding measurements of an object and a representation of that object.

The formula for scale factor is expressed as;

Scale factor = Dimension of the new shape ÷ Dimension of the original shape

This is so for the downgrading of a shape

Now, we have;

Scale factor = Adjacent of the triangle A/adjacent of triangle B

Scale factor = 10/ 4

Reduce to simply forms

Scale factor = 5/ 2

Hence, the scale factor is 5/2
