Answer 2

X1= -1 , x2=3 first step swap both sides the solve, square both sides, move variables to the left, collect terms, reorder terms, rewrite, factors the expressions, then again, then factor negetive sign, factor expression, change sign, split, solve, remove the repeated solution, check it, simply them, the statements are false and true the final solutions are x=1 x=3 x=-1

Find Perimeter

Answers

Answer:

Step-by-step explanation:

10+10=20

8+8 = 16

36 is perimeter of the rectangle

diameter of half circle is 8

formula for circumference of a circle is r π = 8 x 3.14

8 x 3.14 = 25.12 but your not done yet its a half circle so divide by 2

25.12/2 = 12.56

12.56 + 36 = 48.56 is final answer

Urgent!!!

set whether each of the following equations represents a growth or decay

1. f(x)= 3[tex]^{x}[/tex]

2.f(x) = (0.25)[tex]x^{x}[/tex]

3.f(x)= [tex]\frac{2}{3x^{x} }[/tex]

4.f(x) =[tex]\frac{3}{2} x^{x}[/tex]

Answers

Answer:

Notice that the written functions are mostly incorrectly written, after a short online search i've found the correct ones, which are the ones i will write in this answer.

A general exponential equation can be written as:

f(x) = A*(r)^x

Where A is the initial value, r is the rate of growth, and x is our variable.

If r > 1, the function represents a growth.

if 0 < r < 1, the function represents a decay.

1) f(x) = 3^x

Here we have r = 3

This is clearly larger than 1, then this function represents a growth.

2) f(x) = (0.25)^x

Here we have r = 0.25, which is smaller than 1 and larger than zero, then this function represents a decay.

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

here we have r = 2/3 = 0.66

This is larger than zero and smaller than 1, then this function represents a decay.

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

Here we have r = 3/2 = 1.5

This is larger than 1, then this function represents a growth,

Factor the expression using the GCF. A. 2(4a + 8c) B. 4(2a + 4c) C. 8(a + 2c) D. 16( 12 a + c) Not multiple choice

Answers

Note: The expression is missing. Consider the expression is [tex]8a+16c[/tex].

Given:

The expression is

[tex]8a+16c[/tex]

To find:

Factor form of the given expression by using GCF.

Solution:

We have,

[tex]8a+16c[/tex]

Factors of each term:

[tex]8a=2\times 2\times 2\times a[/tex]

[tex]16c=2\times 2\times 2\times 2\times c[/tex]

The common factors are 2, 2 and 2. So,

[tex]GCF(8a+16c)=2\times 2\times 2[/tex]

[tex]GCF(8a+16c)=8[/tex]

Taking out the greater common factor (GCF) in the given expression, we get

[tex]8a+16c=8(a+2c)[/tex]

Therefore, the required expression is [tex]8(a+2c)[/tex] and the correct option is C.

can someone please help me to do this?
