The measure of the angles 2 and 3 are 70°

What is an angle?

An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles created by two rays are located in the plane containing the rays. Angles also were generated when plane cross. These are known as dihedral angles. An angle defined by two intersecting curves is the angle of the rays lying tangent to the respective curves at their point of junction. Angle can also refer to the measurement of an angle or of a rotation. In the case of a geometric angle, the arc is defined by the sides and is centered at the vertex.

Given, angle 1 = 40°

and, angle 2 = angle 3 = x

In a triangle, sum of angles = 180°

or, m∠1 + m∠2 + m∠3 = 180°

or, 2x = 180-40

or, 2x = 140

or, x = 140/2 = 70°

Hence, the measure of the angles 2 and 3 are 70°

The functions whose graphs consist only of lines are-

A function is a relationship between a set of inputs (referred to as the domain) and a set of permissible outputs (referred to as the codomain), in which each input is connected to exactly one output. A function on one variable is frequently denoted by f.

Linear functions: A straight line just on coordinate plane is represented by a linear function. For instance, y = 3x - 2 symbolizes a straight line on the a coordinate plane and thus a linear function.

Constant functions: A constant function is employed to portray a quantity that remains constant over time and is considered the simplest type of real-valued function.

Answer:

81, 100, 25, 4

Step-by-step explanation:

The square root of each of these numbers is whole

Answer:

these are the perfect squares

Step-by-step explanation:

Answer:

x = 45, y = 85

Step-by-step explanation:

In this figure we can see a Z-angle, which tells us that x = 45

In a triangle, the sum of the angles is 180 degrees,

so the unknown angle in the triangle is 180 - 45 - 85 = 50

For a straight line, the total angle is 180 degrees,

, so y + x + unknown angle of triangle = 180

since x = 45, and unknown angle of triangle = 50,

y = 180 - 45 - 50 = 85

This can also be seen when you realise that the two parallel lines give an F-angle, which tells us that Y = 85

We need to find the function in slope-intercept form. We thus need the y-intercept and slope. We know there are 38000 gallons in the pool already, so the y-intercept is 38000. The pool drains 12 per minute, so the slope is -12.

y = mx + b
y = -12x + 38000

To find the time it takes to drain the pool, we need to find x where y = 0, so we set the equation to 0 and solve for x.

0 = -12x + 38000
-38000 = -12x
-38000/-12 = -12x/-12
3167 = x

Now, to fill it back up, the y-intercept is 0. We know the slope is 16, so the equation is:

y = 16x

Finally, we need to find 16x = 38000. This is simple enough.

y = 16x
38000 = 16x
38000/16 = 16x/16
2375 = x

The 96th term of the arithmetic sequence (1, -12, -25,.......) is 1234.

We are provided with the arithmetic sequence mentioned below;

1, -12, -25,...........

We know that, the rule to calculate the nth term in an arithmetic sequence is

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + ( n - 1 ) d                             equation 1

Here, d is the difference between two consecutive terms in the arithmetic sequence , [tex]a_{1}[/tex] is the first term, n is the number of terms and [tex]a_{n}[/tex] is the nth term.

We have,

n = 96

[tex]a_{1}[/tex] = 1

d = -12 -1 = -13

Now, substitute these values in equation 1 i.e, formula of arithmetic sequence and on substituting we will get

[tex]a_{96}[/tex] = 1 + ( 96 - 1 ) ( -13 )

[tex]a_{96}[/tex] = 1 - (95) (13)

[tex]a_{96}[/tex] = 1 - 1235

[tex]a_{96}[/tex] = 1234

So, we can conclude that the 96th term of the arithmetic sequence  is 1234.

Answer:

y = 2x+4

Step-by-step explanation:

2x - y = -4

We add y on both sides:

2x - y + y = -4 + y

so 2x = -4 + y

We now add 4 on both sides:

2x + 4 = -4 + 4 + y,

so 2x+4 = y,

so y = 2x+4

So intercept for y = 2x+4

tan θ = 4.5

Step-by-step explanation:

tan = opposite/adjacent

The opposite of θ is 45 cm long

The adjacent of θ is 10 cm long

tan θ = 45 / 10 = 4.5

The solution is: the value of tan is : tan θ = 4.5.

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

here, we have,

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

Here, we have,

we know,

tan = opposite/adjacent

The equation of the circle in standard form is (x + 5)² + (y)² = 9/4.

The general representation of the equation is:

(x-h)² + (y-k)²= r²

Where (h,k) is the coordinates of the center of the circle and r is the radius.  And x and y are the corresponding x and y values of the point the circle passes through

Since we have the coordinate of the center as (-5,0)  and the circle passes through (-5, 3/2). Therefore:

h = -5, k = 0, x = -5 and y = 3/2

Let's put these values in the formula.

(x-h)² + (y-k)²= r²

(-5 - (-5) )² + (3/2 - 0)² =  r²  

(-5 + 5)² + (3/2)²= r²

(0)² + (3/2)²= r²

(3/2)² = r²

r = 3/2

Putting radius, r = 3/2,   h = -5 and k = 0 back into the formula wiil give:

(x + 5)² + (y - 0)²= (3/2)²

(x + 5)² + (y)² = 9/4

Therefore,the standard form of the equation of the circle is (x + 5)² + (y)² = 9/4.

When analyzing research data, if the difference between group a and group b did not happen by chance and the data showed a real difference, the results are called statistically significant.

Statistically significant results occur in a research data when the difference between two groups is not likely to occur on its own, without the benefit of the independent variable. Statistically significant findings suggest that the researchers' outcomes are unlikely to be a result of chance, and that there is a relationship between the variables under investigation in the larger population. In such cases, the research usually rejects the null hypothesis and accept the alternative hypothesis.

Answer: 72

Step-by-step explanation:

The average is 90.

To calculate the average, you add the grades and divide by the total amount of them. The number of grades is 5. We need to know what value of x satisfies the following equation:

[tex]90 = \frac{96+90+87+95+x}{5}[/tex]

To solve the equation, we first multiply each side by 5, netting:

450 = 96 + 90 + 87 + 95 + x.

Then we subtract each grade from each side.

450 - 378 = 378 - 378 + x

72 = x

[tex]6(y) + 6( -5 ) = 18 - 2y \\ 6y - 30 = 18 - 2y \\ 6y + 2y = 18 + 30 \\ 8y = 48 \\ \frac{8y}{8} = \frac{48}{8} \\ y = 6[/tex]

Probability that x greater than or equal to 5 is 0.6 i.e., Probability that x ≥ 5 = 0.6

The probability distribution for a random variable x is given in the table.

x                |  -10       -5       0       5      10    15     20

probability | 0.20   0.15   0.05   0.1  0.25  0.1   0.15

If a random variable x has values x₁, x₂, .. ,xₙ with their corresponding probabilities given for each of them P(xₐ), then probability that x ≥ xₐ, for some a = 1, 2, .. , n is,

        P(x ≥ xₐ) = P(xₐ) + P(xₐ₊₁) +...+P(xₙ).

Here we need to find the probability that the random variable x is greater than equal to 5. So we need to add up the probabilities corresponding to the random variables x  ≥ 5.

So here, probability that x ≥ 5 is

P(x ≥ 5) = P(5) +P(10) + P(15) + P(20)

            = 0.1 + 0.25 + 0.1 + 0.15
