Answer:
The correct answer would be 15.5 or C.
Answer and explanation:
19.is 5th degree polynomial because the the ^ is 5 witch is a degree of 5 and there is four terms so its a polynomial
20 t will equal 49 because here is my work -16(4)^2+75(4)+5= -16(16)+300+5=-256+300+5=49
now here is some stuff to remember about 19
when ever you see something like 5x^2 its a 2nd degree monomial
when you see 5x^2+5 its a second degree binomial
when you see 6x^4+3x+2 its a 4th degree trinomial
but anything over 3 terms is a polynomial of what ever degree such as ^2 ^3 or even ^5 degree
Hope i helped you learn may i please have brainliest. Please ;)
Answer:
c
Step-by-step explanation:
c appears to be the better description as the line on the left has a solid circle at x = 1 indicating it is defined for x ≤ 1
While the line on the right has an open circle at x = 1 indicating it is defined for x > 1
Both line segments have a negative slope, thus
y = - 2x + 1 x > 1
y = - x + 2 : x ≤ 1
Answer:
There are 252 possible outcomes.
Step-by-step explanation:
For each economic course, the student can select nine mathematic courses.
For each mathematic couse, the student can select four computer courses.
There are 7 economic courses.
So in all, there are 9*4*7 = 252 possible outcomes, that is, the number of different ways which the student can select his courses.
