Answer:
The discriminant of a quadratic equation is a parameter that is used to determine the nature of the roots of the equation. The discriminant can be determined by b2- 4ac. In this case, upon substitution, 25- 4*2*7 = -31 in which the roots are negative and iimaginary.

Step-by-step explanation:
To find the width of the ink pad, we need to use division to find the answer.
<u>We know that:</u>
- Area of ink pad = 98 cm²
- Length of ink pad = 7 cm
- Width = A/L
<u>Solution:</u>
- Width = A/L
- => Width = 98/7
- => Width = 14 cm
Hence, the width of the ink pad is 14 cm.

See Below.
Step-by-step explanation:
Remember multiplicity rules:
- If a factor has an odd multiplicity (e.g. 1, 3, 5...), then the graph will cross the x-axis at that point.
- If a factor has an even multiplicity (e.g. 2, 4, 6...), then the graph will bounce off the x-axis at that point.
From the graph, we can see that at our zeros, the graph always passes through the x-axis.
Hence, we do not have any zeros with even multiplicity since the graph does not "bounce" at any of the zeros.
Answer:
their current cash flow is negative since their expenses are higher than their income:
- monthly net income = $56,000 / 12 = $4,667
- monthly expenses = $1,500 + $3,500 = $5,000
- monthly cash flow = ($333)
they have 3 options:
- Option 1 (which I personally dislike) is that Neil contributes $4,000 less per year to his retirement account in order to balance their net income and expenses. The problem is that once he retires, his income will be much lower.
- Option 2 is that they lower their expenses a little bit, only enough to balance their cash flows.
- Option 3 is that Nancy gets a part time job, maybe a couple of hours per day which will allow her to earn money that can be used to cover some expenses.
Personally I believe that option 2 is the best, but if they definitely cannot lower their monthly expenses, then option 3 would probably fit them.
False because the squares are minimized of the least values.
