What is the classification for this polynomial -3a^2b^5+2a

1 answer:

3 0

$\bf \stackrel{\stackrel{degree}{\stackrel{2+5=7}{\downarrow }}}{-3a^2b^5}+\stackrel{\stackrel{\stackrel{degree}{1}}{\downarrow }}{2a^1}\impliedby \begin{array}{llll} \textit{highest degree of any term is 7}\\ \textit{so is a 7 degree polynomial}\\ \textit{or called a "septic"} \end{array}$

bear in mind that the degree of a polynomial comes from the highest degree of any of its terms, and the degree of a term is the sum of all exponents in the variables.

Answer:

0.3

Step-by-step explanation:

Given:

Number of small dogs = 18

Number of medium-sized dogs = 12

Number of large dogs = 10

To find: probability that a medium-sized dog will be chosen

Solution:

Probability refers to chances of occurrence of some event.

Probability = number of favourable outcomes/total number of outcomes

Total number of dogs = 18 + 12 + 10 = 40

Number of medium-sized dogs = 12

So,

probability that a medium-sized dog will be chosen = Number of medium-sized dogs/Total number of dogs = $\frac{12}{40}=0.3$

Please help me on this

BabaBlast [244]

Answer:

C. 4 weeks

Step-by-step explanation:

We have the formula

$s = 16 \sqrt{7t} + 62$

We are looking for the value of t (number of weeks) when s = 150.

So, we isolate t (well, almost isolate, because it would be hard to read)

$(\frac{s - 62}{16} )^{2} = 7t$

If we replace s by 150 we get:

$7t = (\frac{150 - 62}{16} )^{2} = (\frac{88}{16} )^{2} = (5.5 )^{2} = 30.25$

We have 7t = 30.25. If we divide both sides by 7 we get the number of weeks: 4.32... so rounding it down to 4.

Mrs Lim bought some white rice and some brown rice. She cooked an equal amount of white and brown rice. She had 3/4 of the white

quester [9]

Since she cooked 3/4 of the white rice, there is 1/4 of the white rice that is not cooked. This is equal to 2/8. 2/8+3/8=5/8. This shows that 3/8 of the rice that she bought was cooked. Please mark Brainliest!!!
