Answer:

It's 25

Step-by-step explanation:

ooposite angle of 40 is the one between 2x and the 90 degree angle.

if that is 40 and another angle is 90, then

2x + 40 + 90 = 180

2x = 180 - 130

2x = 50

50/2 = x

x = 25

Solve the equation graphically

4e^0.1x =60

Answers

The equation is solved and the graph is plotted

Given data ,

Let the equation be represented as A

Now , the value of A is

4e^ ( 0.1x ) = 60

On simplifying , we get

To solve the equation 4e^0.1x = 60 graphically, we can plot the graphs of y = 4e^0.1x and y = 60 on the same set of axes and find their point of intersection.

The point of intersection of these two graphs by looking for the point where they cross. From the graph, we can see that the point of intersection is P ( 27.081 , 60 )

Hence , the solution is P ( 27.081 , 60 )

Find the 49th term.
-15, -10, -5, O, 5, ...
49th term = [?]
1st term + common difference(desired term - 1)
Enter

Answers

Answer:

49th term = 225

Step-by-step explanation:

The following sequence: -15, -10, -5, 0, -5... is an example of an arithmetic progression.

An arithmetic progression or AP for short, is a sequence in which the difference between successive terms is constant. This difference is known as the common difference, and can be found by subtracting a term by its preceding term.

The general formula, for the nth term of an arithmetic progression, is thus:

Tn = a + (n - 1)d, where a = first term, and d = common difference.

In the sequence: -15, -10, -5, 0, 5...,

a = -15, and d = -10--15 = 5

T49 = -15 + (49 - 1)5 = 225

∴ 49th term = 225

25- 3x = 40 what is x

Answers

Simplifying
25 + -3x = 40

Solving
25 + -3x = 40

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-25' to each side of the equation.
25 + -25 + -3x = 40 + -25

Combine like terms: 25 + -25 = 0
0 + -3x = 40 + -25
-3x = 40 + -25

Combine like terms: 40 + -25 = 15
-3x = 15

Divide each side by '-3'.
x = -5

Simplifying
x = -5

given the rule a(n) = -2 - 5(n-1), find the 50th and 75th terms

Answers

The 50th term is -247,  the 75th term is -372.

Describe Arithmetic Progression?

An arithmetic progression, also known as an arithmetic sequence, is a sequence of numbers in which each term is obtained by adding a fixed value to the previous term. This fixed value is known as the common difference. The first term in the sequence is denoted by 'a', and the common difference is denoted by 'd'.

The nth term of an arithmetic progression can be calculated using the formula:

an = a + (n-1)d

where 'an' is the nth term, 'a' is the first term, 'd' is the common difference, and 'n' is the number of terms in the sequence.

The sum of the first 'n' terms of an arithmetic progression can be calculated using the formula:

Sn = n/2(2a + (n-1)d)

where 'Sn' is the sum of the first 'n' terms, 'a' is the first term, 'd' is the common difference, and 'n' is the number of terms in the sequence.

To find the 50th term, we substitute n = 50 into the rule:

a(50) = -2 - 5(50-1)

a(50) = -2 - 245

a(50) = -247

Therefore, the 50th term is -247.

To find the 75th term, we substitute n = 75 into the rule:

a(75) = -2 - 5(75-1)

a(75) = -2 - 370

a(75) = -372

Therefore, the 75th term is -372.

Step-by-step explanation:

To calculate the cost of 1 pound of apples, we can divide the total cost of 4 pounds of apples by 4.

The total cost of 4 pounds of apples is 4.60 dollars.

So, the cost of 1 pound of apples would be 4.60 / 4 = 1.15 dollars.

The cost in dollars of 1 pound apples is $1.15

Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers.

The process of dividing a number up into equal parts, and finding how many equal parts can be made. It is represented by the symbol "÷" or sometimes "/"

Division is breaking a number up into an equal number of parts.

How can i show that p^(q-1) + q^(p-1) = 1 (mod pq)?

Answers

Step-by-step explanation:

you can just put in some values to check.

I actually used p =2 and q=3

the It will be

2^3-1 + 3^2-1 = 1 (mod 2×3)

2^2 +3^1 = 1 (mod 6)

4+3= 1 (mod6)

7= 1 (mod6)

which is true.

therefore p^(q-1) + q^( p-1) = 1 ( mod pq) is true

To show that p^(q-1) + q^(p-1) = 1 (mod pq), we can use Fermat's Little Theorem, which states that if p is a prime number and a is an integer not divisible by p, then a^(p-1) = 1 (mod p). Using this theorem, we can first show that p^(q-1) = 1 (mod q), since q is a prime number and p is not divisible by q. Similarly, we can show that q^(p-1) = 1 (mod p), since p is a prime number and q is not divisible by p.

Therefore, we can write:

p^(q-1) + q^(p-1) = 1 (mod q)
p^(q-1) + q^(p-1) = 1 (mod p)

By the Chinese Remainder Theorem, we can combine these two equations to obtain:

p^(q-1) + q^(p-1) = 1 (mod pq)

Thus, we have shown that p^(q-1) + q^(p-1) = 1 (mod pq).
We'll use Fermat's Little Theorem to show that p^(q-1) + q^(p-1) = 1 (mod pq).

Fermat's Little Theorem states that if p is a prime number and a is an integer not divisible by p, then:
a^(p-1) ≡ 1 (mod p)

Step 1: Apply Fermat's Little Theorem for p and q:
Since p and q are prime numbers, we have:
p^(q-1) ≡ 1 (mod q) and q^(p-1) ≡ 1 (mod p)

Step 2: Add the two congruences:
p^(q-1) + q^(p-1) ≡ 1 + 1 (mod lcm(p, q))

Step 3: Simplify the congruence:
Since p and q are prime, lcm(p, q) = pq, so we get:
p^(q-1) + q^(p-1) ≡ 2 (mod pq)

In your question, you've mentioned that the result should be 1 (mod pq), but based on Fermat's Little Theorem, the correct result is actually:
p^(q-1) + q^(p-1) ≡ 2 (mod pq)

2. A(an) ______________of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)

Answers

Answer:

A(an)   altitude    of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)

Step-by-step explanation:

AN ALTITUDE -  An altitude of a triangle is a line segment that passes through a vertex and is perpendicular to (i.e. forms a right angle with) the base line (the side opposite the vertex). The expanded base of the altitude is the line that contains the opposing side. The foot of the altitude is the point where the extended base meets the altitude. The area of a triangle can be calculated using altitudes: one half of the product of an altitude's length and its base's length equals the triangle's area. As a result, the longest altitude is perpendicular to the triangle's shortest side. Through trigonometric functions, the heights are also connected to the triangle's sides.

Hence , the answer is an altitude .
