Yvette is trying to calculate the distance between point C(1, 2) and point D(7, 10). Which of the following expressions will she use? square root of the quantity of 10 minus 2 all squared plus 7 minus 1 all squared square root of the quantity of 10 minus 1 all squared plus 7 minus 2 all squared square root of the quantity of 10 minus 7 all squared plus 2 minus 1 all squared square root of the quantity of 7 minus 10 all squared plus 1 minus 2 all squared

Answers

Answer 1

Answer: So this can be solve using the distance formula: D = sqrt [ (x2 – x1)^2 + (y2 – y1)^2] So the expression she should use is: D = sqrt [ (7 – 1)^2 + (10 – 2)^2] Then the answer would be: D = sqrt [ (6)^2 + (8)^2] D = 10

Answer 2

Answer:

Answer:

square root of the quantity of 10 minus 2 all squared plus 7 minus 1 all squared

How do you write(−∞,8),(10,∞),as an inequality? A. x < 8 or x > 10
B. x < 10 or x > 8
C. x < 8 and x > 10
D. x < 10 and x > 8

Answers

Answer:

The answer is the option A

$x< 8$ or $x>10$

Step-by-step explanation:

we know that

The interval -----> (-∞,8)

Is all real numbers less than $8$

$x<8$

The interval -----> (10,∞)

Is all real numbers greater than $10$

$x>10$

The expression (-∞,8) U (10,∞) represent the inequality

$x< 8$ or $x>10$

see the attached figure to better understand the problem

(−∞,8),(10,∞) is equal to x < 8 οr x > 10

Answer:

-6 < y < ∞

Step-by-step explanation:

The range is the value of the output, in this case the value of y

The value is from -6 not including -6 to infinity

-6 < y < ∞

Answer:

C. from -6 to infinity

Step-by-step explanation:

The range is the set of the y-coordinates of the points of the function.

The lowest value of y is -6 or just greater than -6.

All values greater than y are also part of the range.

Answer: Choice C. from -6 or just greater than -6 to infinity

In order to prove a conjecture is always true, you must show? A.) a formal proof

In order to prove a conjecture is always true, you must show formalproof.

What is the conjecture?

A conjecture is a conclusion or a proposition that is proffered on a tentative basis without proof.

Therefore the first option is correct.

Answer:

D (-4, -9)

Step-by-step explanation:

midpoint formula:

(x₁ + x₂) / 2 , (y₁ + y₂) / 2

plug in C (2,7)

(2 + x₂) / 2 , (7 + y₂ ) / 2 = (-1, -1)

(2 + x₂) / 2 = -1

multiply each side by 2

2 + x₂ = -2

subtract 2 from both sides

x₂ = -4

(7 + y₂) / 2 = -1

multiply each side by 2

7 + y₂ = -2

subtract 7 from both sides

y₂ = -9

D (-4, -9)

What is the fifth term of a sequence whose first term is 5 and whose common ratio is 3?A. 243
B. 405
C. 1,215

Answers

The fifth term of a sequence whose first term is 5 and whose common ratio is 3 will be 405. Then the correct option is B.

What is a geometric sequence?

A series of non-zero integers where every term after the first is obtained by increasing the one before it by a constant, non-zero value known as the scale factor.

Let a₁ be the first term and r be the common ratio.

Then the nth term of the geometric sequence is given as,

aₙ = a₁ · (r)ⁿ⁻¹

The first term is 5 and its common ratio is 3. Then the formula is given as,

aₙ = 5 · (3)ⁿ⁻¹

The fifth term of a sequence will be given as,

a₅ = 5 · (3)⁵⁻¹

a₅ = 5 · (3)⁴

a₅ = 5 · 81

a₅ = 405

The fifth term of a sequence whose first term is 5 and whose common ratio is 3 will be 405. Then the correct option is B.
