I hope this helps you



f (x)=(x+2)^3/2


f'(x)=3/2. (x+2)^3/2-1


f'(x)=3/2 (x+2)^1/2


f'(x)=3/2.square root of (x+2)

Elimination process <br><br> 7a-3b = 26<br> a + 2b =11
VMariaS [17]

Answer:(a=5,b=3)

7a-3b = 26--------(1)

a + 2b =11---------(2)

on mutlplying by7 in eq 2

= 7a+14b=77-------(3)

from eq(1) and (3) (on substracting)

7a+14b=77

7a-3b=26

________

=-17b=51

b=51/17

b=3

on putting value of b in eq 1

7a-3b = 26

=7a-9=26

7a=35

a=5

Classify each function. (a) y = x − 3 x + 3 root function logarithmic function power function trigonometric function rational fu
Studentka2010 [4]

Answer:

a) rational

b) rational

c)exponential

d) power function

e) polynomial function of degree 6

f) trig function

Step-by-step explanation:

Functions can be classified by the operations they contain. Remember the following functions:

  • Power function has as its main operation of an exponent on the variable.
  • Root function has as its main operation a radical.
  • Log function has as its main operation a log.
  • Trig function has as its main operation sine, cosine, tangent, etc.
  • Rational exponent has as its main function division by a variable.
  • Exponential function has as its main operation a variable as an exponent.
  • Polynomial function is similar to a power function. It has as its main function an exponent of 2 or greater on the variable.

Below is listed each function. The bolded choice is the correct type of function:

(a) y = x − 3 / x + 3 root function logarithmic function power function trigonometric function rational function exponential function polynomial function of degree 3

(b) y = x + x2 / x − 2 power function rational function algebraic function logarithmic function polynomial function of degree 2 root function exponential function trigonometric function

(c) y = 5^x logarithmic function root function trigonometric function exponential function polynomial function of degree 5 power function

(d) y = x^5 trigonometric function power function exponential function root function logarithmic function

(e) y = 7t^6 + t^4 − π logarithmic function rational function exponential function trigonometric function power function algebraic function root function polynomial function of degree 6

(f) y = cos(θ) + sin(θ) logarithmic function exponential function root function algebraic function rational function power function polynomial function of degree 6 trigonometric function

In parallelogram HIJK, the measure of angle H is 45∘.
koban [17]

Answer:

The angle diagonal to angle H = 45

The other two angles equal 135

Step-by-step explanation:

A line equals 180. So 45+135 = 180

I'm sorry that I couldn't list names of the angles. I would need a picture. I hope this made since and could help. God bless!
