Answer:

30

Step-by-step explanation:

We can move the triangle on the top to the bottom to form a rectangle.

Then, it is 5x6 = 30.

The equation for the line of best fit is given as follows:

y = 50x/3.

The slope-intercept equation for a linear function is presented as follows:

y = mx + b.

The parameters of the definition of the linear function are given as follows:

From the graph, when x = 0, y = 0, hence the intercept b is given as follows:

b = 0.

Hence:

y = mx.

When x = 3, y = 50, hence the slope m is given as follows:

3m = 50

m = 50/3.

Hence the equation is:

y = 50x/3.

By using the parallelogram method, the addition of the vectors [tex]\vec a + \vec b[/tex] is (3, 1).

In Mathematics, a vector typically comprises two (2) points. First, is the starting point which is commonly referred to as the "tail" and the second (ending) point that is commonly referred to the "head."

Furthermore, the head to tail method of adding two vectors requires drawing the first vector ([tex]\vec a[/tex]) on a graph and then placing the tail of the second vector ([tex]\vec b[/tex]) at the head of the first vector. Finally, the resultant vector would be drawn from the tail of the first vector ([tex]\vec a[/tex]) to the head of the second vector ([tex]\vec b[/tex]).

1) circumference = πd = 16π inches.

arc length = (15/360) X πd = (2/3)π inches.

area of circle = πr² = π(8)² = 64π square inches.

area of sector = (15/360) X 64π = (8/3)π square inches.

2) circumference = πd = 30π inches.

minor arc length = (60/360) X 30π = 5π inches.

major arc length = (300/360) X 30π = 25π inches.

area of circle = πr² = π(15)² = 225π square inches.

area of minor sector = (60/360) X πr² = (75/2)π square inches.

area of major sector = (300/360) X πr² = (375/2)π square inches.

3) circumference = πd = 40π inches.

arc length = (125/360) X 40π = (125/9)π inches.

area of circle = πr² = π(20)² = 400π square inches.

area of sector = (125/360) X 400π = (1250/9)π square inches.

Answer:

If the height and radius of a cone are both 9 yards, then you can use the formula for the volume of a cone to calculate its volume. The formula for the volume of a cone is V = (1/3)πr^2h, where r is the radius of the base and h is the height of the cone. Plugging in the values for r, h, and π gives us:

V = (1/3)πr^2h

 = (1/3)(3.14)(9 yd)^2(9 yd)

 = (1/3)(3.14)(81 yd^2)(9 yd)

 = (1/3)(254.34 yd^3)

 ≈ 84.78 yd^3

So, the volume of a cone with a height and radius of 9 yards is approximately 84.78 cubic yards, rounded to the nearest hundredth.

To find the first four terms of the infinite sequence u_n = 1/(7n - 2), we substitute the values of n from 1 to 4 into the formula:

For n = 1:

u_1 = 1/(7(1) - 2) = 1/5

For n = 2:

u_2 = 1/(7(2) - 2) = 1/12

For n = 3:

u_3 = 1/(7(3) - 2) = 1/19

For n = 4:

u_4 = 1/(7(4) - 2) = 1/26

Therefore, the first four terms of the infinite sequence are:

u_1 = 1/5

u_2 = 1/12

a. The demand equation is p=−300Q+6000.

b. When the price per unit is Rs 1650, the number of calculators demanded is 2500.

c. When 4500 calculators are demanded, the price per unit is Rs 900.

a. The slope of the demand curve is m = 0.3. We can find the y-intercept by substituting the slope and one of the points into the demand equation. When the price is Rs 1200, the quantity demanded is 4000. Therefore, the y-intercept is b=1200−(−0.3)(4000)=2400.

The demand equation is p=−0.3Q+2400.

1650 = 0.3Q - 2400

b. When the price per unit is Rs 1650, the number of calculators demanded is:

= (1650 - 2400) /-0.3

= 2500.

c. To find the price per unit of calculator when 4500 calculators are demanded, we substitute Q = 4500 into the demand equation and solve for p:

Answer: a. A $100 stock loses 20% of its value.

To find the ending value of the stock after a 20% decrease in value, we can multiply the initial value by (1 - 0.20) or 0.80.

Ending value = $100 x 0.80 = $80

Therefore, the ending value of the stock after a 20% decrease is $80.

b. An $80 stock gains 20% of its value.

To find the ending value of the stock after a 20% increase in value, we can multiply the initial value by (1 + 0.20) or 1.20.

Ending value = $80 x 1.20 = $96

Therefore, the ending value of the stock after a 20% increase is $96.

The cardinality of set A (n(A)) is 3.

The cardinality of set B (n(B)) is 4.

To find the cardinality of a set, we count the number of elements in that set.

For set A, we need to count the number of integers between -6 and -4 (inclusive).

The integers in this range are -6, -5, and -4.

Therefore, the cardinality of set A (n(A)) is 3.

For set B, we simply count the number of elements given in the set. From the given set B = {-29, 20, 28, 29}, we have 4 elements.

Therefore, the cardinality of set B (n(B)) is 4.

the angle immediately to the left of 20x must be 25x. that's because the two lines with double arrows at the top are parallel lines.

the angle to the left of 20x and the 25x are called alternate angles. they are equal.

also, 20x and the angle to the left of it are on a straight line. angles on a straight line add up to 180°.

so, we now have 20x + 25x = 180.

45x = 180

The slope of the line tangent to the graph of h(x) = 1/x + 3 at the point when x is -6 is -1/36.

To determine the slope of the line tangent to the graph of the given function when x = -6;

Using alternative form of the definition of derivative.

f'(a) = lim (h->0) [f(a+h) - f(a)] / h

Using this formula for the given function;

h'(a) = lim (h->0) [h(a+h) - h(a)] / h

Now, substitute a = -6 into the formula:

h'(-6) = lim (h->0) [h(-6+h) - h(-6)] / h

Next, simplify the expression by plugging in the values:

h'(-6) = lim (h->0) [1/(-6+h) + 3 - (1/-6 + 3)] / h

Simplifying further:

h'(-6) = lim (h->0) [1/(-6+h) - 1/-6] / h

Now, let's combine the fractions with a common denominator:

h'(-6) = lim (h->0) [(-6 - (-6+h))/((-6+h)(-6))] / h

Simplifying the numerator:

h'(-6) = lim (h->0) [-h / ((-6+h)(-6))] / h

Canceling out the h's:

h'(-6) = lim (h->0) [-1 / ((-6+h)(-6))]

Taking the limit as h approaches 0:

h'(-6) = -1 / ((-6)(-6))

Simplifying further:

The greatest number of children that can distribute the mangoes equally is 481. Each child will receive 481/481 = 1 mango.

In order to distribute the mangoes equally among children, we first need to determine the total number of mangoes in the bag.

If there are 215% (or 2.15) of 224 mangoes in the bag, we can calculate the total number of mangoes by multiplying these values: 2.15 * 224 = 481.6 mangoes.

Since we cannot have fractional mangoes, we round down to the nearest whole number, which gives us a total of 481 mangoes in the bag.

To distribute these mangoes equally among the children, we divide the total number of mangoes by the number of children. Let's assume there are 'x' children.

Each child will receive 481/x mangoes.

To determine the greatest number of children, we need to find a value for 'x' that evenly divides 481. We can do this by finding the factors of 481. The factors of 481 are 1, 13, 37, and 481.
