Eva is showing her work in simplifying (7. 3 – 7. 2) – 3. 8 + 3. 7. In which step did Eva make an error?
Step 1: (7. 3 – 7. 2) – 3. 8 + 3. 7
Step 2: 7. 3 + (–7. 2 – 3. 8) + 3. 7 (commutative property)
Step 3: 7. 3 – 11 + 3. 7
Step 4: 7. 3 + 3. 7 – 11 (commutative property)
Step 5: 11 – 11 = 0

Answers

Answer 1
Eva didn’t calculate (-7.2 - 3.8) correctly. The correct answer is -3.4 instead of -11.

Which expression is equivalent to n5 • k5 • n-5 • k?



a. N^5 k


b. N^-25 k^5


c. K^6


d. (nk)^6

Answers

The expressions are algebraic expressions, and the equivalent expression of n⁵ * k * n⁻⁵ * k is k⁶

How to determine the equivalent expression?

The expression is given as:

n⁵ * k⁵ * n⁻⁵ * k

Rewrite the expression as:

n⁵ * k * n⁻⁵ * k = n⁵ * n⁻⁵ * k⁵ * k

Apply the law of indices

n⁵ * k * n⁻⁵ * k = k⁶

Hence, the equivalent expression of n⁵ * k * n⁻⁵ * k is k⁶

[tex]\frac{2x}{x+5}[/tex]

Step-by-step explanation:

We are given a function for f and g, and are asked to find f/g.

We know f = 4x^2 + 6x and g = 2x^2 + 13x + 15

Simply put function of f over g.

[tex]\frac{4x^2+6x}{2x^2+13x+15}[/tex]

Factor:

[tex]\frac{2x(2x+3)}{(2x+3)(x+5)}[/tex]

Since both numerator and denominator have 2x + 3, we can cancel them out.

[tex]\frac{2x}{x+5}[/tex] is our answer.

What is the range?
2 ,9 ,7 ,9 ,1 ,6

Answers

Answer:

8

Step-by-step explanation:

The range is the difference between the highest and lowest values in a data set.

Highest value = 9Lowest value = 1Range = 9 - 1 = 8

Answer:

8

Step-by-step explanation:

When finding the range, you have to subtract the smallest value from the biggest value,

2, 9, 7, 9, 1, 6

⇒ 1, 2, 6, 7, 9, 9

If we take a look at the set of numbers, we can see that 1 is the smallest value and 9 is the biggest,

Now that know that we need to subtract,

9 - 1

= 8

Therefore the range of this set of numbers is 8.

Find the diameter of the circle with the given circumference. Use 3.14 for pi . C=18 cm

Answers

Answer:

Step-by-step explanation:

We work our way backward to find the diameter.

Circumference of a Circle Formula:

[tex]C=2\pi r[/tex]

r is radius , 2*radius = diameter.

Given information: C=18 cm , pi=3.14.

[tex]C=2\pi r\\18=2\pi r\\[/tex]

Get r by itself.

[tex]r=18/2\pi\\r=9/\pi[/tex]

r≈2.864788976
