The apothem = 87 cm = 0.87 m.

Using the formula [tex]A=\frac{1}{2}ap[/tex] to find the area of the base, where a is the apothem and p is the perimeter, we get [tex]A=\frac{1}{2}(0.87)(6)=2.61[/tex]

The gradient of the given graph is 1.5

From the question, we are to determine the gradient of the graph

Gradient is given by the formula

[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

Where m is the gradient

Picking the points (-2, -2) and (2, 4) on the line

Then,

x₁ = -2

y₁ = -2

x₂ = 2

y₂ = 4

Putting the parameters into the equation, we get

[tex]m = \frac{4--2}{2--2}[/tex]

[tex]m = \frac{4+2}{2+2}[/tex]

[tex]m = \frac{6}{4}[/tex]

m = 1.5

Hence, the gradient of the given graph is 1.5

The number of possible passwords is 26^4 * 10^4.

We will make 4 picks from each category (letters and numbers).

We can duplicate them (i.e., pick each character more than once.)

so, for your 4 picks from the letters, you'll have

26 * 26 * 26 * 26 = 26^4 possible selections.

For each of these, you'll have 4 picks from the digits. Similar reasoning, this works out to

10^4 combinations of digits.

This means you'll have 26^4 * 10^4

Possible combinations of 4 letters and 4 digits, and, for each of these, you now need to work out how many unique ways to arrange them.

Answer:

60

Step-by-step explanation:

Let's call the number A.

We are told that:

(2/3)A - 8 = 32

Multiply both sides by 3 and rearrange:

3*[(2/3)A - 8 = 32]

2A - 24 = 96

2A = 120

A = 60

CHECK:

Does (2/3) of 60 minus 8 equal 32?

(2/3)*(60) = 40

40 - 8 = 32

YES

The Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side. The length of QS can lie between 3 < QS < 13.

The Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.

Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,

Here, we have,

As per the given law of triangle inequality, the sum of the two sides of the triangle is greater than the third side.

x + 8 > 5

x > -3

x + 5 > 8

x > 3

8 + 5 > x

Answer:

A. The function is always decreasing

Step-by-step explanation:

we read a graph from left to right, so we can always compare the increase/decrease of a function by seeing how an x value compares with an x value to the left

(I am aware that this paragraph is really confusing)

we can see that as x increases, from -∞ to 0,

y decreases in correspondence

and that as x increases, from 0 to ∞,

y decreases in correspondence also

So, even though the graph doesn't quite look like it, when x < 0; the function decreases, when x > 0; function decreases--so the function is always decreasing

hope this helps!! have a lovely day :)

The correct expression for the inverse proportion is k/6 = 3/1

The longest possible altitude of the third altitude (if it is a positive integer) is 83.

According to statement

Let h is the length of third altitude

Let a, b, and c be the sides corresponding to the altitudes of length 12, 14, and h.

From Area of triangle

A = 1/2*B*H

Substitute the values in it

A = 1/2*a*12

a = 2A / 12 -(1)

Then

A = 1/2*b*14

b = 2A / 14 -(2)

Then

A = 1/2*c*h

c = 2A / h -(3)

Now, we will use the triangle inequalities:

2A/12 < 2A/14 + 2A/h

Solve it and get

h<84

2A/14 < 2A/12 + 2A/h

Solve it and get

h > -84

2A/h < 2A/12 + 2A/14

Solve it and get

h > 6.46

From all the three inequalities we get:

6.46<h<84

Answer:

x = -5

Step-by-step explanation:

We can use the below formula to find the line of symmetry.

( x - a )² + b

Here,

line of symmetry = +a

Vertex = +b

And now let us take a look at the given equation.

y = x² + 10x + 22

To find the line of symmetry from the given equation we have to make the given equation as the given formula.

Let us use the completing square method for that.

y = x² + 10x + 22

Put zero instead of y.

x² + 10x + 22 = 0

x² + 10x = -22

x² + 10x + 25 = -22 + 25

( x + 5 )² = 3

( x + 5 )² -3 = 0

Therefore,

line of symmetry of the line is = -5

∴ x = -5

So the explicit formula is generally defined as [tex]a_n = a_1 + d(n-1)[/tex]. where d is essentially the "slope", basically how much it's changing from term to term. anyways if you look at the recursive formula you'll notice it's taking the previous term and subtracting 4. This is what d is going to be, -4 and since a_1 is given you plug that in as well. This gives you the equation

b) The two triangles are similar by SAS

Step-by-step explanation:

From the diagram below, we can tell that

SAS similarity (Side-Angle-Side similarity) is a criterion used to determine whether two triangles are similar.

It states that if two sides of one triangle are proportional to two sides of another triangle, and the included angles between these sides are congruent, then the two triangles are similar.

In other words, if in two triangles, the ratio of the lengths of corresponding sides is equal, and the included angles between these sides are congruent, then the two triangles are considered similar.

Among the options, only a rational number (35/60) is equivalent to a repeating decimal. The correct answer is option (d).

To identify which of the given rational numbers is equivalent to a repeating decimal, we need to check their decimal representations.

a. 24/60 = 2/5 = 0.4 (terminating decimal, not repeating)

b. 30/64 = 15/32 = 0.46875 (terminating decimal, not repeating)

c. 29/50 = 0.58 (terminating decimal, not repeating)

d. 35/60 = 7/12 = 0.583333... (repeating decimal, as 3 repeats infinitely)

Among the options, only option d (35/60) is equivalent to a repeating decimal.

Using the Poisson distribution, it is found that there is a 0.507 = 50.7% probability that the bird feeder will be visited by at most 5 birds in a 45 minute period during daylight hours.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by:

Considering the average of 15 birds every 2 hours during daylight hours, the mean for a 45-minute period is given by:

[tex]\mu = 15 \times \frac{45}{120} = 5.625[/tex]

The probability that the bird feeder will be visited by at most 5 birds in a 45 minute period during daylight hours is given by:

[tex]P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)[/tex]

In which:

[tex]P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-5.625}(5.625)^{0}}{(0)!} = 0.004[/tex]

[tex]P(X = 5) = \frac{e^{-5.625}(5.625)^{5}}{(5)!} = 0.169[/tex]

Then:

[tex]P(X \leq 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) = 0.004 + 0.02 + 0.057 + 0.107 + 0.15 + 0.169 = 0.507[/tex]
