The right angle congruence theorem is used to prove that two triangles are congruent.

Solution:

In the given triangles, the corresponding hypotenuse and the corresponding angle are equal. So, the congruence used here is the Hypotenuse-Angle congruence that implies ABC is congruent to DEF.

Thus, the answer is Hypotenuse-Angle congruence.

Answers:

================================================

Explanation:

Focus on (4,5) and (4,-4)

The input x = 4 leads to simultaneous outputs y = 5 and y = -4 at the same time. This is not allowed in a function. For a function to be possible, each input x must lead to exactly one y output.

Therefore, this given relation is not a function.

-----------

Domain = set of possible x inputs

Range = set of possible y outputs

The statement "An element from the domain is paired with more than one element from the range" basically means we have an x value paired with more than one y value. Therefore, this statement is true since I mentioned (4,5) and (4,-4) earlier.

Answer: 52900 Naira

Step-by-step explanation:

1) Use the equation A = P(1+r/n)^nt

A = Ammount

(Starting Cash) P = 40,000

(Intrest rate) R = 15%

(Number of periods) n = N/A

(Time) t = 2

2) Make an equation

A = 40,000(1+15%)^2

3) Solve the equation.

A = 40,000(1+0.15)^2

A = 40,000(1.15)^2

A = 40,000(1.3225)

A = 52900

The option that describes the equation 4x =-20 will be C. What number, when multiplied by four, is equal to negative twenty?

It should be noted that an equation is used to show the relationship between the variables.

In this case, the equation given us illustrated as:

4x = -20

The appropriate question that fits this will be that what number, when multiplied by four, is equal to negative twenty. This can be illustrated as:

4x = -20

Divide through

x = -20 / 4

x = -5

In conclusion, the correct option is C.

Answer:

Step-by-step explanation:

Given:

Charge for each repair = $75

Additional charge per hour = $42

The expression is used to calculate the total charge, in dollars, for each repair appointment:

75 + 42h

Let h represent the number of hours Susna works during an appointment.

To find the total charge if Susan works for 6 hours, substitute 6 for h in the expression and evaluate.

Thus, we have:

h = 6

75 + 42h

75 + 42(6) = 75 + 252 = 327

Therefore, the total charge in dollars if Susan works for 6 hours is = $327

at X= 0 the function f(x) = 2/6x^3 is not differentiable

Since 1/0 cannot be differentiated and the denominator will become zero when x=O, the function is not defined. Sharp points, cusps, and discontinuities in the graph indicate that a function is "not differentiable." Additionally, it implies that at that same location, we can draw an endless number of tangents. There is therefore no special tangent at that place. Even at x=0, the provided function is not defined. (If you plug in x=0, you get (1/0), which is undefined and leaves you with nothing to do.)) Only after a function is clearly defined at a certain moment do we discuss its continuation. And only if the function is continuous at the place do we talk about differentiability.

The equation of line passing through (-4, -16) and (5, 2) are y = 2x – 8, y - 2 = 2(x - 5) and y + 16 = 2(x + 4)

An equation is an expression that shows the relationship between two or more numbers and variables.

Equations are classified based on degree (value of highest exponents) as linear, quadratic, cubic and so on. Variables can be dependent or independent. Dependent variables depend on other variable while an independent variable do not depend.

The standard form for linear equation is:

y = mx + b

Where m is the slope and b is the y intercept

The equation of line passing through (5, 2) and (-4, -16) is:

y - 2 = [(-16-2)/(-4-5)](x - 5)

y - 2 = 2(x - 5)

For the graph of a linear function x=-3 and y=4 is horizontal line , the equation for this linear function is y = 0(x) +4.

As given in the question,

Graph of a required linear function is a horizontal line.

Given :

When x=-3 y=4

Two coordinates of the required linear function are :

(x₁ ,y₁) = (-3, 4)

(x₂, y₂) = ( 0,4)

Equation of the linear function :

(y -y₁) /(x-x₁) = (y₂ -y₁) / (x₂- x₁)

⇒( y-4)/(x+3) =(4-4)/(0+3)

⇒ (y-4)/(x+3) = 0/3

⇒ y = 0(x) +4

Therefore, for the graph of a linear function x=-3 and y=4 is horizontal line , the equation for this linear function is y = 0(x) +4.

Probability of x successes given the probability p of success on a single trial is 0.0154.

When a process is repeated a certain number of times (for example, in a set of patients), the result for each patient can either be a success or a failure, the binomial distribution model enables us to calculate the probability of witnessing a defined number of "successes." In probability theory and statistics, the discrete probability distribution of the number of successes in a series of n independent experiments, each asking a yes-or-no question and each with its own Boolean-valued outcome: success or failure, is known as the binomial distribution with parameters n and p.

Given Data

n = 6

X = 3

p = [tex]\frac{1}{6}[/tex]

Binomial distribution

P(X = x) = ₙCₓ(pˣ)(qⁿ⁻ˣ)

Clare can go 3 times for her workout cycle

Clare follows the same workout cycle each time she goes to the gym

She spends 1 1/2 hour at the gym

First, she runs 1/3 of an hour

After that, she lifts 1/3 of an hour

The first step is to convert to minutes

60 mins = 1 hour

1/2 × 60

= 30

30 + 60

= 90 mins

convert 1/3 to mins

1/3 × 60

= 20 mins

convert 1/6 to mins

1/6 × 60

= 10 mins

Total mins= 20 + 10

= 30 mins

Rectangular garden has sides:

The perimeter is sum of all the 4 sides.

So, we can say:

Where

w is width

l is length

Width is 19.5, so we find length:

84 = 2(19.5) + 2l

84 = 39 + 2l

2l = 45

l = 22.5 feet

Now, area is given by:

Area = length * width

Area = 22.5 * 19.5 = 438.75 sq. ft.
