Classify each polynomial by its degree and by its number of terms.

Mathematics

Stella [2.4K]3 years ago

Answer:

a. Degree 4; 2 terms

b. Degree 2; 3 terms

c. Degree 3; 1 term

Step-by-step explanation:

Here, all you need is a few definitions. The "degree" of a polynomial is just the highest exponent you see, and be careful with this, because sometimes the exponents won't be arranged from high to low. In this case, they are. In a polynomial, a "term" is basically anything that sits between a plus/minus operation (i.e in 5x + 4, 5x and 4 are both "terms").

a. What's the highest exponent you see? 4. So the degree is 4. You have 5x^4 and 8 separated by a minus sign, so that'll be 2 terms.

b. The highest exponent here is just 2, so it's a degree 2 polynomial. Two minus signs, so count 'em up: 3 terms.

c. Highest exponent is 3, and since 9m^3 sits on its own, you only have the one term.

Note that something like 3abc is one term. 3a/b is also one term. So is 4ab^2cd. If it's being multiplied or divided, they're together like a family. Addition or subtraction separates terms; multiplication and division don't.

Step-by-step explanation:

<u>Step 1: Define</u>

9m - m + 3 = -2(m + 1)

<u>Step 2: Solve for </u><em><u>m</u></em>

  1. Combine like terms:                    8m + 3 = -2(m + 1)
  2. Distribute -2:                                8m + 3 = -2m - 2
  3. Add 2m on both sides:                10m + 3 = -2
  4. Isolate <em>m</em> term:                             10m = -5
  5. Isolate <em>m</em>:                                      m = -1/2

Maria's height while jumping on a a trampoline can be modeled by the equation h=-16t^2+18t+5. Where t=time in seconds and h=heig
Vadim26 [7]

Answer:

10.06 ft

Step-by-step explanation:

Maria's maximum height will occur when her velocity reaches zero (0). This means that she has stopped ascending and is about to begin descent.

The equation for the height reached by Maria on the trampoline is given as:

h=-16t^2+18t+5

To find her maximum height, we first have to find the time it will take her to get to that height and corresponding velocity (zero).

Her velocity can be found by differentiating her height i.e. dh/dt:

v = \frac{dh}{dt} = -32t + 18

Therefore, when v = 0:

0 = -32t+ 18\\\\=> 32t= 18\\\\t = 18 / 32 = 0.5625 secs

It takes her 0.5625 seconds to get to her maximum height.

Therefore, her height at that time (0.5625 seconds) is:

h=-16(0.5625)^2+18(0.5625)+5\\\\h = -16 * (0.3164) + 10.125+5\\\\h = -5.0624 + 15.125\\\\h = 10.06 ft

Therefore, her maximum height is 10.06 ft.
