Answer: the y intercept is 4.

Step-by-step explanation:

In the graph, if the savings account would’ve started with $8, the y intercept would be 8.

We don’t know what the graph is talking about so it’s not the last option.

The line crossed the x intercept at 8 so it’s not B.

If u(x) = x^5 - x^4 + x^2 and v(x) = -x^2, which expression is equivalent to (u/v)(x)

Alchen [17]

$\dfrac{u(x)}{v(x)}=\dfrac{x^5-x^4+x^2}{-x^2}=\dfrac{x^5}{-x^2}-\dfrac{x^4}{-x^2}+\dfrac{x^2}{-x^2}\\\\=-x^3+x^2-1$

The appropriate choice is ...
C) -x^3 + x^2 - 1

What are the roots of the equation 16x² + 16x + 5 = 0 in simplest a + bi form?

Greeley [361]

Answer:

Below in bold.

Step-by-step explanation:

Using the quadratic formula :

roots = [-16 +/-√(16^2 - 4*16*5)] / (2*16)

= -0.5 +/- √(-64) /32

= -0.5 +/- 8i/32

= -0.5 + 0.25i and -0.5 - 0.25i

Combine like terms to create an equivalent expression. Enter any coefficients as simplified proper or improper fractions or inte

Sonja [21]

Answer:

1 -9/7n

Step-by-step explanation:

$\dfrac{1}{7}-3\left(\dfrac{3}{7}n-\dfrac{2}{7}\right)=\dfrac{1}{7}-\dfrac{3\cdot3}{7}n+\dfrac{3\cdot2}{7}=\dfrac{1}{7}+\dfrac{6}{7}-\dfrac{9}{7}n\\\\=\dfrac{1+6}{7}-\dfrac{9}{7}n=\boxed{1-\dfrac{9}{7}n}$

Can you help me to create a histogram graph with the following data please?

AlekseyPX

The attached graph represents a histogram that has a range of 55

<h3>How to create the histogram?</h3>

The range is given as:

Range = 55

The range is calculated as:

Range = Maximum - Minimum

So, we have:

Maximum - Minimum = 55

Rewrite as:

Maximum = Minimum + 55

Let the minimum be 10.

So, we have:

Maximum = 10 + 55

Evaluate

Maximum = 65

The following dataset can be used to create the histogram

Score Frequency

10 2

15 5

45 3

65 1

This is so because it has a range of 55

See attachment for the histogram
