Answer:

8 square units

Step-by-step explanation:

For a triangle,

area = base × height / 2

We need to identify a base and a height for this triangle, and then use them in the area formula above.

Use BC as the base.

A height of a triangle is usually inside the triangle, but not always.

The height of a triangle is a segment that is perpendicular to the a side, or the line containing a side, and intersects the opposite vertex.

In this case, for base BC, the height is a segment from point (-2, 2) to point A.  The length of the height is 4.

area = 4 × 4 / 2

area = 8 square units

The inflation rate is 16.71 %

As we know the inflation rate is given by the percentage error.

We know that the formula for the percentage error:

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ] x 100

Let us assume that A represents the inflation rate of percentage error.

Here, the cost of the Jolly Peanut butter is = $ 3.59

So , the original cost = $ 3.59

The increased cost of Jolly Peanut butter is = $ 4.19

So , the new rate = $ 4.19

Now , the inflation rate is given by the formula of percentage error,

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ] x 100

A = [ ( 4.19 - 3.59 ) / 3.59 ] x 100

A =  ( 0.6 / 3.59 ) x 100

A = 0.16713 x 100

A = 16.71 %

c. The difference between votes percentage and seats percentage for democrat is 4% and 26% respectively. The difference between votes percentage and seats percentage for republican is 3% and 26% respectively.

The pie chart is given below:

a. We have to identify the party that won the highest percentage of votes and seats in 1982.

We can see that in diagram that gray part of circle shows the vote percentage of democrat and white part of circle shows the vote percentage of republican.

Republican gain votes in 1982 = 52%

Democrat gain votes in 1982 = 49%

So the democrats get the maximum votes in 1982.

b. We have to describe a change between the percentage of seats won by republicans in 1982 and 2012.

In 2012 republican get votes percentage = 48%

In 1982 republican get votes percentage = 52%

So the change between 1982 and 2012 = (52 - 48)% = 4%

c. We have to draw a conclusion about the difference in percentage of votes won and seats.

In 2012 republican get votes percentage = 48%

In 1982 republican get votes percentage = 52%

So, the difference between vote percentage is 4%.

In 2012 republican get seats percentage = 25%

In 1982 republican get seats percentage = 51%

So, the difference between seats percentage is 26%.

In 1982 democrat get votes percentage = 49%

In 2012 democrat get votes percentage = 52%

So, the difference between vote percentage is 3%.

In 2012 democrat get seats percentage = 75%

288 m³ is The Volume Of The Pyramid.

The space occupied inside an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

Given, The base of the pyramid shown has a length of 9m and a width of 8m. The height of the pyramid is 12m.

Since, The Formula for the volume, V , of a pyramid is V = 1/3Bh ,

where B is the area of the base of the pyramid and h is the pyramid's height.

Since, Area of rectangle = Width *height

Thus, Area of the base = 9 * 8

Area of the base = 72 m²

So, the volume of pyramid (V) =  1/3Bh

the volume of pyramid (V) = 1/3 * 72 * 12

the volume of pyramid (V) =  288 m³

According to Bernoulli's theorem, the success rate for the situation is 0.7173.

In math Bernoulli's theorem is states that that random experiment with exactly two possible outcomes, "success" and "failure" in which the probability of success is the same every time the experiment is conducted.

In order to calculate p we must sum the possible permutations of getting 0 success of 10 trials, 1 success of 10 trials, and 2 successes of 10 trials, and divide this sum by the total possible subsets from 10 elements, then it can be written as,

=> P = (10 1) (10 2) (10 1) / 2¹⁰

When we simplify this one, then we get,

=> P = 56/1024

=> P = 0.0547

When we apply the value on Bernoulli's theorem, then we get,

=> B(340, 0.0547, 0) = ( 340 0 ) x (1/1024) x (1023/1024)³⁴⁰

Answer: To find r'(1), we need to use the chain rule of differentiation, which states that:

r'(x) = f'(g(h(x))) * g'(h(x)) * h'(x)

In this case, we know that:

h(1) = 2, g(2) = 4, h'(1) = 4, g'(2) = 4, and f '(4) = 7

Therefore:

r'(1) = f'(g(h(1))) * g'(h(1)) * h'(1) = f'(g(2)) * g'(2) * h'(1) = 7 * 4 * 4 = 112

So, the derivative of r(x) with respect to x at x = 1 is 112

a) The binomial expansion of (1+12x)^1/2 is given by:

(1+12x)^1/2 = 1^1/2 + (1/2)(1^-1/2)(12x) + (1/2)(1^-1/2)(-1/2)*(12x)^2 + ...

Binomial expression: what is it?

A polynomial with only terms is a binomial. An illustration of a binomial is x + 2, where x and 2 are two distinct terms. Additionally, in this case, x has a coefficient of 1, an exponent of 1, and a constant of 2. As a result, a binomial is a two-term algebraic expression that contains a constant, exponents, a variable, and a coefficient.

The first four terms, in ascending powers of x, are:

1, (1/2)(12x), (1/8)(12x)^2, (1/16)*(12x)^3

b) To use x=1/36 in the expansion, you would substitute x=1/36 into the expansion, and keep only the terms up to x^3 (the fourth term in the expansion). This will give an approximation of the value of (1+12x)^1/2 when x=1/36.

This will be an approximation of √12 because x=1/36 corresponds to 12x = 1 and the initial value of the expansion is 1 + 12x .

We can use this approximation to approximate square root of 12 and also for other square roots by using appropriate x values.

Answer: the second, third and fifth options.

Step-by-step explanation:

When an equation is set up in a y=mx+b format, the slope is always equal to the value m.

The length of PQ in terms of MO if ∠POQ = 120° is PQ = -x * √3/3.

Let MO = x.

Since MO is perpendicular to plane α, MP and MQ form right angles with MO.

Using the Pythagorean Theorem, we have:

MP = x * tan(30°) = x * √3/3

MQ = x * tan(60°) = x * √3

Since ∠POQ = 120°, we have:

PQ = MP * 2 * cos(120°)

= 2 * x * √3/3 * -1/2

= -x * √3/3

Therefore, the length of PQ in terms of MO is PQ = -x * √3/3.

If the image of point (x,5) is (-6, y) when it is translated by the vector t(6 -2), then the values of x = -12 and y = 3.

Vector translation is a mathematical concept that describes how an object is moved in space. It involves the use of a vector, which is a quantity that has both magnitude and direction. A vector can represent a displacement, a velocity, an acceleration, or any other physical quantity that has both magnitude and direction.

When an object is translated by a vector, it moves a certain distance in a specific direction. This is usually done by adding the vector to the current position of the object. The magnitude of the vector determines the distance of the translation, while the direction of the vector determines the direction of the translation.

Additionally, the vector can be used to rotate the object. This is done by multiplying the vector by the object’s rotation matrix. The result is the object's new orientation in space, which can be used to orient the object in a different direction.

Vector translation is used in a variety of applications, including computer graphics, robotics, and navigation systems. It i also used in mathematics and physics to represent physical phenomena, such as forces, velocities, or accelerations.

Let the point P(x,5) be translated by the vector t(6,-2).

The image of point P is (x',y') = (x+6,5-2) = (-6,y)

Therefore, x+6 = -6

=> x = -6-6 = -12

Similarly, 5-2 = y

=> y = 5-2 = 3

So the value of x is -12 and y is 3.
