What conjecture can you make about the sum of the first 33 positive odd numbers?

Answers

Answer:

The number series 1, 3, 5, 7, 9, . . . . , 59. Therefore, 900 is the sum of first 30 odd numbers.

The conjecture we can make is C. The sum is equal to the no. of terms squared.

According to the given question we have been asked What conjecture can you make about the sum of the first 33 positive odd natural numbers.

We know that the sum of first 'n' odd natural numbers is n².

So, the sum of first 33 odd natural numbers is (33)² which is = 1089.

Let us prove this by AP.

First term(a₁) is = 1.

common difference(d) = 2.

No. of terms (n) = 33.

∴ aₙ = a₁ + (n-1)d

aₙ = 1 + (33-1)2

aₙ = 1 + 32(2).

aₙ = 1 + 64.

aₙ = 65.

∴ S₃₃ = 33/2×[ 2(1) + (33-1)2].

S₃₃ = 33/2×[ 2 + 64].

S₃₃ = 33/2×66.

S₃₃ = 33×33.

S₃₃ = 1089.

O Divide both sides by D.

which step should I take

Answers

Answer:

Divide both sides by V

Step-by-step explanation:

The equation is not well written.

Mariko needs to solve the equation below for D. Here is the equation:

M = DV

For Mariko to get D, he needs to make D the subject of the formula by dividing both sides of the equation by the coefficient of D i.e V as shown;

Divide both sides by V

M/V = DV/V

V at the denominator will cancel out the V at the numerator to have:

M/V = D

Rearrange

D = M/V

Therefore, the statement which correctly describes the step he should take is:

Divide both sides by V. Option B is correct.

Felipe and Makayla each tried to solve the same

Describe the first step Felipe made to the equation

Answers

Felipe subtract 3x from both side to get rid of x on one side. Ik this isn’t part of the answer but the correct way to do this would be to subtract 2x from each side after adding 8 to each side of the equation

Felipe in the first step shifted 3x from R.H.S. to L.H.S. as -

2x - 3x + 6 = 8

What is a function?

An expression in mathematics defines a relationship between one variable (the independent variable, x)  and another variable (the dependent variable, y). For example -

f(x) = 4x + 6

Given is the equation equating two functions as -

2x + 6 = 3x - 8

We have -

2x + 6 = 3x - 8

2x - 3x + 6 = 8

-x + 6 = 8

Therefore, Felipe in the first step shifted 3x from R.H.S. to L.H.S. as -

2x - 3x + 6 = 8

[tex]20x-8=18x+6[/tex]

To illustrate their plans to the county commission, they use a coordinate plane. The southbound track will have an equation of 2x + 5y = 15. What is the equation of the parallel northbound track that runs through the point (4, – 2)?

Answers

Answer:

there are no signs between the x and y and constant

it could be

2x+5y=15

2x+5y=-15

-2x+5y=15

2x-5y=15

for ax+by=c, the equation of a line paralell to that is

ax+by=d where a=a, b=b, and c and d are constants

(for this answer, I'm going to use 2x+5y=15)

given 2x+5y=15, the equation of a line paralell to that is 2x+5y=d

to find d, subsitute the point (4,-2), basically put 4 in for x and -2 for y to get the constant

2x+5y=d

2(4)+5(-2)=d

8-10=d

-2=d

Triangle ABC is translated 5 units to the right and 4 units up to create triangle A'B'C'.
What is the measure of B?

Answers

I believe it is 74°. Because translations preserve size

The measure of the angle B is 74 degrees.

What is the angle sum property?

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

Triangle ABC is translated 5 units to the right and 4 units up to create triangle A'B'C'.

If triangle ABC is translated 2 units up and 2 units right, that means that all the vertices of the triangle are translated by the same units 2 up and 2 right.

The angle sum property of a triangle;

80 + 26 + B = 180

B = 180 - 106

B = 74

Therefore, the size and shape of the triangle wouldn't change.

The triangle A'B'C' will still have the same size and shape, and all the sides will have the same length.

Hence, the measure of the angle B is 74 degrees.

Which statement is modeled by 2p + 5 < 11
Group of answer choices

The sum of 5 and 2 times p is at least 11

5 added to the product of 2 and p is less than 11

2 times p plus 1 is at most 11

the product of 2 and p added to 5 is 11

Answers

Answer: 5 added to the product of 2 and P is less than 11

The reason for this is because the inequality multiples 2 and the variable p, which is the product. Then, you have to add 5 to the product of 2p. Since the sign is opened towards the 11, this indicates that the sum of 5 and 2 times p is less than 11. Hope that helps!
