3x + 6x^2 Is this a third-degree polynomial in standard form?

1 answer:

6 0

No. For it to be in standard form the term with the largest exponent comes first. Standard form would be 6x^2-3x. It is a second degree polynomial because 6x is raised to the 2nd power. It would be a third degree polynomial if the largest degree was raised to the 3rd power.

What is 25 percent of 148

valentina_108 [34]

Answer: 37

Step-by-step explanation: To find 25% of 148, first write 25% as a decimal by moving the decimal point two places to the left to get .25 which is the decimal equivalent to 25%.

Next, the word "of" means multiply so we will need to multiply.

(.25) (148) = 37

Therefore, 37 is 25% of 148.

Hey, I don´t understand the graphing part of inequalities.

stiks02 [169]

Answer:

See explaination

Step-by-step explanation:

While graphing inequalities, think of the inequality sign as an equal sign.

So, y=mx+b.

Say the inequality was y>3x+7, I would think fo the > as an equal sign.

So, in your head, "write" it like this: y=3x+7. Hope this helps.

Can anyone help with this???

VikaD [51]

Answer:

56.25

Step-by-step explanation:

The number you need to add to both sides to complete the square needs to be calculated by doing ( $\frac{b}{2}$ )². So, in this problem, b= -15.

-15/2 = -7.5, and -7.5² = 56.25. This is the number you will add to complete the square

Raymond has $800 in a savings account that earns 10% interest per year.The interest is not compounded. How Much Interest Will He

Gennadij [26K]

The amount of interest he would earn in one (1) year is equal to $80.

<u>Given the following data:</u>

Interest rate = 10% = 0.1

Principal = $800

Time = 1 year

To determine how much interest he would earn in one (1) year:

<h3>How to calculate simple interest</h3>

Mathematically, simple interest is given by this formula:

$I = PRT$

<u>Where:</u>

S.I is the simple interest.

P is the principal or starting amount.

R is the interest rate.

T is the time measured in years.

Substituting the given parameters into the formula, we have;

$I=800 \times 0.1 \times 1$

Simple interest = $80
