Answer:

Step-by-step explanation:

Slope - intercept formula: y = mx + b, where m- slope, b- y-intercept

1. Points are:

Slope is:

y-intercept is - 6 as per graph

Then the formula is

2. Points are:

Slope is:

y-intercept is 5 as per point

Then the formula is

3. Points are:

Slope is

y-intercept is -5 as per graph

Then the formula is

Answer:

23. y = 47

Step-by-step explanation:

40 + 5x =180 (angls on a straight line add up to 180 degrees)

5x=140 (minus 40 from both sides)

x = 28 (divide both sides by 5)

3y - 1 = 140

3y =141 (add 1 to both sides)

y = 47 (divide both sides by 3)

Answer:

y=47

Answer:

Step-by-step explanation:

we know that density is given as

density=mass/volume

the volume of the cylinder

v= πr^2h

v=3.142*1.5^2*14.4

v=3.142*2.25*14.4

v=101.8cm^3

Given that density =0.00123g/cm^3

mass= density*volume

masss= 0.00123*101.8

mass= 0.125214 g

Answer:

what's the whole question

Step-by-step explanation:

In a rhombus, both pairs of opposite angles are congruent

so m<4=32 degrees

so your answer is 32 DEGREES

Answer:

The function is strictly increasing on (0, π/2)

Step-by-step explanation:

We are given the function;

y = sin x

Let's find the derivative;

dy/dx = cos x

Now, Cos 0 = 1

Cos (π/4) = 1/√2

Cos (π/2) = 0

From the above, we can see that as x approaches 0 from (π/2), the value of (cos x) approaches 1. This means it's increasing from 0 to 1.

Thus, the function is strictly increasing on the interval (0, π/2)

Answer:

D. (0, pi/2)

Step-by-step explanation:

If you graph y=sin(X) (I used desmos) then you find that the graph is increasing from 0 to pi/2  :)

Answer:

$46.20

Step-by-step explanation:

Since it was discounted 30%, this means that 30% of the original price was taken off. To find the price remaining after the discount, you subtract 30% from 100% which would give you 70%. Then multiply $66.00 and 0.7 and you will get $46.20

Answer:

The correct option is;

20-gon

Step-by-step explanation:

The area, A, of a regular polygon is given as follows;

[tex]A = \dfrac{n \times s \times a}{2} = \dfrac{P_p \times a}{2}[/tex]

Where;

n = The number of sides

s = The length of one side of the polygon

a = The apothem

[tex]P_p[/tex] = The perimeter of the polygon

Where

The area of a circle, A[tex]_c[/tex] = π×r² = π × r × r = 2× π × r × r/2 = P/2 × r

Given that the apothem, a, of a 20-gon circumscribed about a circle is approximately the length of the radius of the circle, and the perimeter of the 20-gon is approximately the perimeter (circumference) of the circle, the area of the 20-gon circumscribed about a circle provides the best estimate for the area of the circle.

Step-by-step explanation:

so first you gotta add up all the animals in the zoo

2+4+3+6 which equals 15

then you gotta see how many goats there are there are 6 goats

so 6/15 are goats

U CAN REDUCE

so what number can divide into 6 and 15 evenly? 3!!!!!

so u divide 6 by 3 to get 2

then u divide 15 by 3 to get 5

NOW U GOT THE ANSWER 2/5

Answer:

  y = 9x -3

Step-by-step explanation:

The given line is in "slope-intercept form"

  y = mx + b

where m is the slope and b is the y-intercept (where it crosses the y-axis).

In your given line, we have ...

  m = 9, b = 4

__

A parallel line will have the same slope, so we know that the line you want has m = 9. You are told to make the line cross the y-axis at -3, so that makes b = -3. Putting these values into the slope-intercept form gives the desired equation:

  y = 9x -3

_____

The attached graph is intended to show the lines are parallel and the equation given here meets the requirement for a crossing of the y-axis at -3. The vertical and horizontal scales are different in order to better show these things.

Answer:

B

Step-by-step explanation:

The domain of the function 'f' represents  the set of all whole numbers.

A function is a relation between two sets. One set is called domain of the function and the other one is called range range of the function.

Given function is: f(x) = 0.41x.

f(x) represents the cost of mail.

Here, x represents the number of letters in the mail.

It can't be real numbers because, real numbers consist of negative numbers, fractions, etc.

It can not be integers, real numbers consist of negative numbers.

Therefore, the domain of must be all whole numbers.
