EASY MATH THAT I DON,T GET PLZ HELP QUICKLY​

Mathematics
1 answer:
jolli1 [7]3 years ago
6 0

Answer:

Terms: 4

Degree: 3

Leading coeff: 7

Step-by-step explanation:

a term is either a single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs, or sometimes by division. 7x³+5x²-3x+1 would have 4 terms: 7x³, 5x², -3x, and 1

You already have the degree which is the highest power in a polynomial

The leading coefficent is the coefficient in the term with the highest power, in this case being 7.

hope this helps!

The vectors x and y are unit vectors that make and angle of 30 degrees with each other. Calculate the value of | 2x + y | and th
ICE Princess25 [194]

Answer: the value of | 2x + y | = 1.39

the direction of 2x + y = 21° 

Step-by-step explanation:

Given that the vectors x and y are unit vectors that make and angle of 30 degrees with each other.

Let assume that unit vector x is along the positive x-axis, and unit vector y is at +30°.

Therefore 

2x-y=

2< 1,0 > - < cos(30),sin(30) >

=<2-(√2)/2, 0-1/2>

and

|2x-y|=√((2-(√2)/2)² + (-1/2)^2)

=1.3862 

Therefore the value of | 2x + y | = 1.39

=atan((-1/2)÷(2-(√2)/2))

=atan(1.29289/-0.5)

=-0.369 radians

= -21.143° 

Therefore the direction of 2x + y is

21°

Which statement describes the graph?
max2010maxim [7]

Answer : D

From the given graph , we can see that

The graph crosses the y axis at 7

So y axis is (0,7)

The graph is increasing at first  and reaches (-2,8)  and then start  decreasing

The graph start increasing at x=-10  and goes on increasing till x= -2

then the graph start decreasing at x=-2  and goes in decreasing till x= 10

The graph crosses the y axis at (0,7), increasing from x=-10  to x=-2  and decreasing from x=-2 to x=10

Answer D is correct

A population of size 3,624 grows at a rate of 3% per year, compounded continuously. How big will the population be in 2 years?
rodikova [14]

Answer:

Step-by-step explanation:

The continuous compound formula is

y=Pe^{rt where P is the principle or starting value, r is the growth rate in decimal form, and t is the time in years. For us:

y=3624e^{(.03)(2)}\\y=3624e^{.06}\\y=3624(1.061836547)\\y=3848.09

which would probably round to just 3848 people.
