1 answer:
Troyanec [42]3 years ago
7 0

Answer:

B is correct.

Step-by-step explanation:

Quadratic Expression (Standard Form) is:

\displaystyle \large{a {x}^{2}  + bx + c}

To say it simply, the expression must have 2 as the highest degree.

This means that if there are any higher or lower degrees than 2 then they are not quadratic expression.

A choice is not quadratic expression because it has 1 as the highest degree.

B choice is correct because 2 is the highest degree.

C choice is wrong because 3 is the highest degree.

D choice is wrong because it is not a polynomial.

Therefore, B is correct.

Is 5/6 less than 2/12
Ostrovityanka [42]
No, 5/6 is greater.

1) First, you have to get a common denominator, lets use 12
2) To get from 6 to 12 you would multiply times 2
3) Do the same to the numerator(the top number) which is to multiply 5 x 2
4) 5 x 2= 10 
5) So, now your fraction has become 10/12

And let me ask you, which is bigger, 10/12 or 2/12
(10/12 is bigger and 2/12 is less)

A sail in the form of a right triangle the angle at its lower edge is 55 what is the size of the angle formed at the top of the
Mars2501 [29]

Answer:

The size of the angle formed at the top of the sail is 35.

Step-by-step explanation:

We know that the sum of all angles inside a triangle must be 180. This is a rule.

So we know that a right triangle is called like that because one angle is a 90-degree angle.

Then we have that:

180 = right angle + lower edge angle + angle top of the sail

180 = 90 + 55 + angle top of the sail

Solving for 'angle top of the sail' we have:

angle top of the sail = 180 - 90 - 55 = 35

The size of the angle formed at the top of the sail is 35.

In slope-intercept form, what is the equation of the line passing through the points (2, 13) and (5, 22)
KiRa [710]
(2,13),(5,22)
slope = (22 - 13) / (5 - 2) = 9/3 = 3

y = mx + b
slope(m) = 3
use either of ur points...(2,13)...x = 2 and y = 13
now sub and find b, the y int
13 = 3(2) + b
13 = 6 + b
13 - 6 = b
7 = b
so ur equation is : y = 3x + 7 <===
