Answer:

Step-by-step explanation:

hello

calculate x : 3x+2 =5

means : 3x+2-2 =5-2

3x = 3

so : x = 3/3 =1

1 is the  element in domain has the image 5 under function f(x)= 3x+ 2

The remaining amount of the sample after 't' days would be 51. 74g

We have the formula for amount to be;

A = Ao × (1/2)^ t/t^1/2

Where

t1/2 = half -life = 138 days

t = 1

Ao  = 52g

A = Amount after decay

Substitute into formula

A = 52 × (1/2) ^ 1/138

A = 52 ×

[tex] { \frac{1}{2} }^{0.00724} [/tex]

A = 52 × 0. 9950

A= 51. 74 g

Thus, the remaining amount of the sample after 't' days would be 51. 74g

There were 4 number of treatment conditions compared in this experiment for the given degree of freedom.

We have,

df = 3, 36

Now,

We know that,

Degree of freedom (df) = Number of treatments (t) - 1

i.e.

df = t - 1

So,

We have,

df = 3

Now,

Substituting the values,

We get,

3 = t - 1,

i.e.

Answer:

x= 10 y=14 : 10 3 point, 14 5 point

Step-by-step explanation:

Write your equation down vertically,

3x + 5y = 100

 x + y   =  24

Next find multiply bottom equation by one number from the tops opposite,

3x + 5y = 100

(-3)x +(-3)y = (-3)24

3x + 5y = 100

-3x - 3y= -72

Add the two functions to isolate y

2y= 28 y=14

Plug y back into original and solve

3x +5(14) =100 --> 3x + 70 =100 --> 3x = 30 x=10

The equation passing through the point ()8, 2 and parallel to 6x - 9y = -7 is y = 6 / 7x - 2 / 7

The equation of the line passes through the point (8, 2) and it is parallel to 6x  - 7y = -7.

The equation of a line can be represented as follows;

y = mx + b

where

m = slope

b = y-intercept

Therefore, parallel line have the same slope.

6x  - 7y = -7

7y = 6x + 7

y = 6 / 7 x + 1

m = 6 / 7

Hence, using (8, 2)

2 = 6 / 7 (8) + b

2 = 16 / 7 + b

b = 2 - 16 / 7

b =  14 - 16/ 7

b = - 2 / 7

Hence, the equation is y = 6 / 7x - 2 / 7

Answer: Option (2)

Step-by-step explanation:

The inverse of a function swaps the domain and range.

The inverse of the function h(x) is

B. h'(x) = ((-5, 3), (-7, 5), (-9, 6), (-12, 10), (-16, 12)}

Option B is the correct answer.

We have,

The function h(x) is given as:

h(x) = {(3, -5), (5, -7), (6, -9), (10, -12), (12, -16)}

To find h¹(x) (the inverse of h(x)), we need to swap the x and y values in each ordered pair.

The inverse function will have the y-values of h(x) as the x-values, and the x-values of h(x) as the y-values.

So,

h¹(x) would be:

h¹(x) = {(-5, 3), (-7, 5), (-9, 6), (-12, 10), (-16, 12)}

Thus,

Answer:

13 + [tex]\sqrt{89}[/tex]

or

22.43398... (depends on how you round it)

Step-by-step explanation:

1. The question stated that the radius of the circle O is 5, so the length of AO and CO is 5.

2. Since line AB and line CB are both tangent to the circle, they have the same length. CB is 8, so AB will also be 8.

--> Both triangle AOB and COB share one side, and the other side (radius) has the same length, so the third side must be the same length

3. Tangent means having a 90-degree angle with the radius. We know that the triangle AOB is a right triangle since the angle OAB is 90 degrees.

We can use the Pythagorean theorem to find side OB. OB^2 = AO^2 + AB^2.

--> OB^2 = 25 + 64

--> OB^2 = 89

--> OB = [tex]\sqrt{89}[/tex]

Now that we know the lengths of all three sides, we can add them up.

--> 5 + 8 + [tex]\sqrt{89}[/tex]

--> 13 + [tex]\sqrt{89}[/tex]

The system of equations is given as:

4x + 3y = 2

3x − 2y = 10

Multiply (1) by 2 and (2) by 3.

So, we have:

9x − 6y = 30

Add both equations

17x = 34

Divide by 17

Angles that are complementary angles have a sum of 90 degrees.

Complement of the angle = (90 - x)

Therefore, we would have:

x = (90 - x) + 8.8

x = 90 - x + 8.8

x = 98.8 - x

x + x = 98.8

2x = 98.8

The graph of y=sin(x-3π/2) is the graph of the y =sinx shifted right by 3π/2 units.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

If we have a parent function y = Sin(x), the function

y = Sin(x-b) would be the parent shifted b units right

y = Sin (x+b) would be the parent shifted b units left

The function given is y=sin(x-3π/2)

So from the rules, we can clearly say that it is parent function shifted right by 3π/2 units.
