Answer:

Trinomials

Step-by-step explanation:

Trinomials take the form of x^2+bx+c usually

and that is what the equation is in.

Binomials are like (x-2)(x+3) in which you have to multiply each parenthesis item by eachother so you would do the previous equation as (x-2)(x+3) like

x times x plus x times 3 plus -2 times x plus -2 times 3.

If that is confusing, just ignore what I wrote right here because you will or you already learned this and it is a pain to type.

Monomials are like 3xy^2 where there is one term, terms being the group of the variables and coefficient numbers which can even be paired up with an exponent, so 3xy^2+4y^2 there are two terms which are both bolded.

Polynomials are like -2x+7.

Hope this explains some of the other questions if they are similar!

This guy explains polynomials really well! Credits and cheers!

Not sure if this relates to your topic but it's the binomial theorem.

12. We use rule/law #2 of logarithms to condense log 2 - log 5. True O False

Sergio [31]

Answer:

log (2/5)

Step-by-step explanation:

The rule/law you have in mind is as follows: log a - log b = log (a/b).

Thus, your log 2 - log 5 = log (2/5).

Phonesmart is having a sale on Bananas. If you buy one Banana at full price, you get a second at half price. When couples come i

Mice21 [21]

Answer:

The probability that a couple buys a pair of Bananas is 1/3 or 33.3%

Step-by-step explanation:

Let's recall that the formula of probability is:

Probability = Number of favorable outcomes/Total number of possible outcomes

What is the probability that a couple buys a pair of Bananas?

For answering this question, we first need to calculate the probability of buying a first Banana, given that when couples come in to buy a pair of phones, sales of Apricots and Bananas are equally likely:

Probability of buying a first Banana = 1/2

Probability of buying a first Apricot = 1/2

Now, we can calculate the probability of buying a second Banana, given that the second phone is twice as likely to be a Banana rather than an Apricot.

Probability of buying a second phone = 1

Probability of buying a second Apricot = x

Probability of buying a second Banana = 2x

Solving for x, we have:

x + 2x = 1

3x = 1

x = 1/3 ⇒ 2x = 2/3

Thus, probability of buying a second Banana = 2/3

Finally,

Probability that a couple buys a pair of Bananas = Probability of buying a first Banana * Probability of buying a second Banana

Replacing with the values we know:

Probability that a couple buys a pair of Bananas = 1/2 * 2/3 = 2/6 = 1/3

1/3 = 33.3%

Probability that a couple buys a pair of Bananas = 1/3 or 33.3%

Magda saw a triangular sign with a base of 4 feet and a height of 2.8 feet. She reasoned that if she first divided each dimensio

motikmotik

Answer: She is not correct, because she must multiply the base and the height of the triangle and then divide by 2.

Step-by-step explanation:

1. The formula for calculate the area of a triangle is shown below:

$A=\frac{b*h}{2}$

Where $b$ is the base and $h$ is the height.

2. Then, if she applied the method she reasoned, she'd obtain the following area:

$b=\frac{4ft}{2}=2ft\\h=\frac{2.8ft}{2}=1.4ft\\A=2ft*1.4ft\\A=2.8ft^{2}$

3. But actually, Magda should multiply the base and the height of the triangle and then divide by 2. Then, the correct area is:

$A=\frac{4ft*2.8ft}{2}=5.6ft^{2}$

If a CONE has a DIAMETER of 10 centimeters and a Volume of 225 cubic centimeters, what is its approximate HEIGHT

ch4aika [34]

Answer:

The approximate height is 8.9 cm

Step-by-step explanation:

To find the height of a cone with a diameter of 10 cm and a volume of 225 cubic centimeter, we will follow the steps below;

first, write down the formula for finding the volume of a cone

v=πr² $\frac{h}{3}$

where v is the volume of the cone

r is the radius and h is the height of the cone

from the question given,

diameter = 10 cm but d=2r this implies that r= $\frac{d}{2}$ r= 10/2 = 5cm

hence r= 5cm

Also v= 225 cm³

π is a constant and is ≈ 3.14

We can now proceed to insert the values into formula and then solve for h

v=πr² $\frac{h}{3}$

225 ≈ 3.14 × 5² × $\frac{h}{3}$

225 ≈ 78.5 × $\frac{h}{3}$

225 ≈ $\frac{75.8 h}{3}$

cross-multiply

675 = 75.8 h

divide both-side of the equation by 75.8

8.9 ≈ h

h≈ 8.9

Therefore, the approximate height is 8.9 cm
