According to given conditions, Gradient = -4/5, y-intercept = 9/5, x-intercept = 9/4.

What is co-ordinate geometry ?

Coordinate geometry is a branch of mathematics that deals with the study of geometric shapes using a coordinate system. In this system, points are identified by their positions in relation to two or more perpendicular lines called axes.

To find the gradient and intercepts of the line 4x+5y-9=0, we need to rearrange the equation into the slope-intercept form y=mx+b, where m is the slope and b is the y-intercept.

First, we can solve for y:

4x + 5y - 9 = 0

5y = -4x + 9

y = (-4/5)x + 9/5

Now we can see that the slope (m) of the line is -4/5 and the y-intercept (b) is 9/5. To find the x-intercept, we can set y=0 and solve for x:

(-4/5)x + 9/5 = 0

-4x + 9 = 0

x = 9/4

So the x-intercept is (9/4, 0).

To sketch the line, we can plot the y-intercept at (0, 9/5), the x-intercept at (9/4, 0), and draw a straight line passing through both points:

Therefore, according to given conditions, Gradient = -4/5, y-intercept = 9/5, x-intercept = 9/4.

Step-by-step explanation:

law of cosine

c² = a² + b² - 2ab×cos(C)

c is the side opposite of the C angle. a and b are the other 2 sides.

AB² = 4² + 4² = 16 + 16 = 32

AB = c = sqrt(32) = 5.656854249...

since a and b are equal (isoceles triangle), so must be the angles at A and B.

the sum of all angles in a triangle is always 180°.

180 = angle A + angle B + angle C

= angle A + angle B + 120

since angle A = angle B we get

180 = 2×angle A + 120

2×angle A = 60°

angle A = angle B = 30°.

Answer:

the limit of sin(1/θ) as θ approaches 0 is equal to 0.

Step-by-step explanation:

To evaluate this limit:

lim θ→0 sin(1/θ)

we can use the squeeze theorem. First, we note that -1 ≤ sin(1/θ) ≤ 1 for all values of θ, since the sine function oscillates between -1 and 1.

Next, we consider the limit of two other functions, -1/|θ| and 1/|θ|, as θ approaches 0:

lim θ→0 -1/|θ| = -∞

lim θ→0 1/|θ| = ∞

Since sin(1/θ) is always between -1/|θ| and 1/|θ|, we can apply the squeeze theorem to conclude that:

lim θ→0 sin(1/θ) = 0

Therefore, the limit of sin(1/θ) as θ approaches 0 is equal to 0.

The area of the forest will be approximately 1396 km sq. after 10 years.

Given that, a forest covers an area of 2100 km sq and that each year this area decreases by 4%..

If the area of the forest decreases by 4% each year, then after one year it will be 96% of the original size.

After two years, it will be 96% of 96% of the original size, or 0.96² of the original size.

After ten years, it will be 96% of itself ten times, or 0.96¹⁰ of the original size.

So the area of the forest after 10 years will be:

Area = Initial area × 0.96¹⁰

Area = 2100 km sq × 0.96¹⁰

Area = 1396 km sq

Therefore, the area of the forest cover in 10 years will be 1396 km sq.

The correct answer is 5.88 × 1013 miles. This is because a light-year is the distance that light can travel in one year, or approximately 5.88 × 1012 miles.

A light year is a unit of distance used to measure astronomical distances. It is the distance that light travels in a vacuum in one year, which is equal to 9.46 trillion kilometres. This means that light travelling at a speed of 300,000 kilometres per second would take one year to travel nine trillion kilometres. T

To find the distance of a star from Earth, one must multiply the number of light-years by 5.88 × 1012. In this case, the star is 9.8 × 101 light-years away, meaning that it is 9.8 × 101 times 5.88 × 1012 miles, or 5.88 × 1013 miles, away from Earth.

Light-years are a unit of distance used by astronomers to measure the great distances between stars and galaxies. Light travels at a speed of approximately 186,000 miles per second, and one light-year is the distance that light can travel in one year. For example, a star that is 9.8 × 101 light-years away from Earth is approximately 5.88 × 1013 miles away from Earth.

Out of the given options, only √196 is a rational number.

A rational number is a number that can be expressed as the ratio of two integers. In other words, it can be written in the form of p/q where p and q are integers and q is not equal to zero.

√56 cannot be simplified further and has no integer factors that can be canceled out to express it as a ratio of two integers. Therefore, it is an irrational number.

Similarly, √63 and √240 cannot be simplified further and do not have any integer factors that can be canceled out to express them as a ratio of two integers. Therefore, they are also irrational numbers.

On the other hand, √196 simplifies to 14 which is a ratio of two integers (14/1). Hence, it is a rational number.

In summary, only √196 is a rational number out of the given options.

Answer: In a parallelogram, opposite angles are congruent. So we know that angle A is congruent to angle C. Let's call the measure of angle A "y".

Therefore, we have:

angle A = y

angle B = 3x + 36

angle C = y (because opposite angles in a parallelogram are congruent)

angle D = 6x - 6

The sum of the measures of the angles in a parallelogram is 360 degrees. So we can write an equation:

angle A + angle B + angle C + angle D = 360

Substituting in the values we know:

y + (3x + 36) + y + (6x - 6) = 360

Simplifying:

2y + 9x + 30 = 360

2y + 9x = 330

Now we have an equation with two variables. But we also know that angle A and angle C are congruent, so y = angle A = angle C. Substituting this into the equation above:

2(angle A) + 9x = 330

2(angle A) = 330 - 9x

angle A = (330 - 9x)/2

Therefore, the measure of angle A is (330 - 9x)/2.

The indicated z-score is 0.84.

The standard normal distribution, also known as the Gaussian distribution or the bell curve, is a probability distribution that describes a set of data points that are normally distributed around the mean with a known variance. It is characterized by its mean, which is 0, and its standard deviation, which is 1. The shape of the distribution is symmetric and bell-shaped, with the highest probability density occurring at the mean.

From the given information, we know that the shaded area under the curve is 0.1949. This area corresponds to the probability that a random variable from a standard normal distribution falls between the mean and some unknown value, which we'll call "z".

Looking up the standard normal distribution table or using a calculator, we find that the z-score corresponding to an area of 0.1949 is approximately 0.84.

For evaluating the relationship between two numbers or quantities, we employ the ratio formula. The general manner of representing a ratio of between two quantities say 'a' and 'b' is a: b, which is interpreted as 'a is to b'.

A ratio describes how much of one quantity is necessary in relation to another. It is possible to combine and express the two terms in the ratio in their simplest form.

Given : total people entered = 18

           people didn't finish = 2

So, people who finished = total people entered - people didn't finish

                                         = 18 - 2

The probability that a person who walked also sailed is 1/8.

Probability is used to make predictions about the likelihood of future events, based on past observations or available information. It is widely used in fields such as statistics, finance, engineering, and science to analyze and model uncertain systems and processes.

Out of the 50 people, 3 did not participate in either walking or sailing. So, the number of people who participated in at least one activity is:

50 - 3 = 47

Out of these 47 people, 40 took part in walking and 18 took part in sailing. However, we need to subtract the number of people who participated in both activities because we don't want to count them twice. Let's call this number "x":

x = number of people who participated in both walking and sailing

So, the number of people who participated in at least one of the activities is:

40 + 18 - x

We know that there were 50 people in total, so we can write:

40 + 18 - x + 3 = 50

Simplifying this equation, we get:

55 - x = 50

x = 5

So, 5 people participated in both walking and sailing.

Now, we want to find the probability that a person who walked also sailed. Since there were 40 people who walked and 5 of them also sailed, the probability is:

Answer:

We'll start with the left-hand side (LHS) of the identity, which is:

sin x (1 + cot^2 x)

We can rewrite cot^2 x as (cos x / sin x)^2, since cotangent is the reciprocal of tangent. Substituting this into the LHS, we get:

sin x (1 + (cos x / sin x)^2)

Now we can simplify the expression in the parentheses by using the identity:

tan^2 x + 1 = sec^2 x

Rearranging this identity, we get:

tan^2 x = sec^2 x - 1

Substituting this into our expression, we get:

sin x (1 + (cos x / sin x)^2) = sin x (1 + (cos^2 x / sin^2 x))

= sin x (sin^2 x / sin^2 x + cos^2 x / sin^2 x)

= sin x ((sin^2 x + cos^2 x) / sin^2 x)

= sin x (1 / sin^2 x)

= sin x / sin^2 x

= 1 / sin x

Now we'll simplify the right-hand side (RHS) of the identity, which is:

csc x

We know that csc x is the reciprocal of sin x, so we can rewrite the RHS as:

1 / sin x

This is the same as the expression we obtained for the LHS, so we have shown that:

sin x (1 + cot^2 x) = csc x

And this proves the identity!
