Which mapping diagram is NOT a function?

The complete trigonometry ratios are sin(220) = -sin(40) and cos(220) = cos(140) and the angles are 40 and 220 degrees

Angle 1

The trigonometry ratio of the angle is given as

sin(220)

Expand the above expression

sin(220) = sin(180 + 40)

Apply the sine rule

sin(220) = sin(180)cos(40) + cos(180)sin(40)

Evaluate the ratios

sin(220) = 0 x cos(40) - sin(40)

So, we have

sin(220) = - sin(40)

So, the measure of the angle is 40 degrees

Angle 2

The trigonometry ratio of the angle is given as

cos(220)

Expand the above expression

cos(220) = cos(360 - 140)

Apply the cosine rule

cos(220) = cos(360)cos(140) + sin(140)sin(360)

Evaluate the ratios

cos(220) = 1 x cos(140) + sin(140) x 0

So, we have

cos(220) = cos(140)

So, the measure of the angle is 140 degrees

1) Problems like these, we can solve by writing an equation.

2)Since that tomato plant grew 150% after three weeks we can write the following

Note that in the parentheses we have the factor of growth. Since it's 150% we can add to 1 and write 1 +1.5=2.5

3) Thus, the answer is:

His temperature was 100.1 degree farad initially which is around 6 pm. At 7 pm it became 101 degree farad.

y = mx + b

where

m = slope

b = y - intercept

let find the y intercept

Therefore, the equation is

e. let us draw a graph

His temperature will be critical above 22 minutes past 9 pm.

f . He should go to emergency room.

g.

His temperature will be normal around past 4 pm which is 98.6 degree farad.

1) To find the relative maxima of a function, we need to perform the first derivative test. It tells us whether the function has a local maximum, minimum r neither.

2) Let's find the points equating the first derivative to zero and solving it for x:

4) Finally, for the inflection points. We need to perform the 2nd derivative test:

Now, let's plug this x value into the original function to get the y-corresponding value:

Bobby is right because the measurements were made smaller so the dilation factor must be a number less than 1, and 1/3 is less than 1

Answer:

600

Step-by-step explanation:

2 X 3 = 6

20 has one 0

30 has one 0

one 0 and one 0 is two 0s

6 plus two 0s = 600

by the distributive law x(y+z)=zy+xz, we have

Then we use the properties of inequalities, we can switch both sides, and if we add or multiply something on both sides the equality remains

we want the variables and the numbers without variables to be in different side, so, first we add 20 to both sides, note that the -20 will be cancelled

we want to left all the numbers with variable on the right side so we substract 3b (add -3b) to both sides. Same as before, the 3b will be cancellated (we can change the order in the sum)

of course, you're welcome

I was asking if you have understood my explanation so far

tell me

it doesn't matter the order, in fact, when you get used to the method you can work with both at the same time

any other question?

yes, you could substrac 3b first

For example

sadly I will need to leave since my shift is over, but if you ask another question one of my partners will help you

Have a nice evening!!!!

then we add like terms and switch both sides

And then we multiply by 1/5 both sides

Answer:

The difference is aproximately 3700.

Step-by-step explanation:

First, we'll round each number to the nearest hundred:

Now, we can estimate the difference:

This way, we can conlcude that the difference is aproximately 3700.

Given that the required linepasses through the points (15, 5)and (5, 15).

Find the slope of the line using teo-point formula.

Substitute the value of m into theslope-intercept form y = mx+c.

Plug in the point (5, 15)to find c, the y-intercept.

Thus, y = -x + 20, which is the required equation of line.

we have the following:

Answer: 3/8

Step-by-step explanation:

Given:

[tex]B-(-\frac{1}{8} )+c[/tex]

replace variables with their given values: b = 2 and C = 7/4

[tex]2-(-\frac{1}{8})+\frac{-7}{4}[/tex]

to make subtracting and addition easier, make each number has the same common denominator.

[tex]\frac{16}{8} -(-\frac{1}{8})+(\frac{-14}{8})[/tex]

Finally, solve equation.

***remember that subtracting a negative is the same as just adding and adding by a negative is the same as simply subtracting.

[tex]\frac{16}{8} -(-\frac{1}{8})+(\frac{-14}{8})=\frac{16}{8} +\frac{1}{8}-\frac{14}{8}[/tex]

= 3/8

Answer:

3/8

Step-by-step explanation:

2 - (-1/8) + (-7/4)

= 17/8 - 7/4

= 17/8 + -7/4

= 3/8

The Variance of a set of data is defined as the average of the square of the deviation from the mean.

The first step is to calculate the mean of the data.

Now we take the difference from the mean, square it, and then average the result.

Hence, the variance of the data is 6.7 (rounded to the nearest tenth)

We have that a group of points can be:

Coplanar: if they lie in the same plane

Collinear: if they lie in the same line

We have to solve the system of linear equations:

We can substract 2 times the second equation for the first equation and solve for y:

Now, we can solve for x:

Answer: (x,y)=(6,-11)

Ok, so:

We're going to factor this expression:

3a² - 24a + 48

First of all, we multiply and divide by 3 all the expression, like this:

3(3a² - 24a + 48) / 3

Now, we can rewrite this to a new form:

( (3a)² - 24(3a) + 144) / 3

Then, we have to find two numbers, whose sum is equal to -24 and its multiplication is 144.

And also we distribute:

((3a - 12 ) ( 3a - 12 )) / 3

Notice that the numbers we're going to find should be inside the brackets.

So, these numbers are -12 and -12.

Now, we factor the number 3 in the expression:

(3(a-4)*3(a-4))/3

And we can cancel one "3".

Therefore, the factored form will be: 3 (a - 4) (a - 4)

So, the answer is B.

The given inequality is expressed as

We would add 10 to both sides of the inequality. It becomes

We would divide both sides by - 3. This would cause the inequality symbol to reverse. It becomes

The graph would be

The shaded circle at the position of - 2 indicates that- 2 is inclusive

Considering the given fractions

You have to find the least common denominator between the denominators "20" and "50"

For these values, the least common denominator is the least common multiple between both values:

So, the least common denominator is 100.

ANSWER

all four sides have a length of 5

EXPLANATION

The distance between two points (x₁, y₁) and (x₂, y₂) is,

Let's find the distance between each pair of points, WX, XY, YX, and WZ,

Hence, using the distance formula we found that all four sides have a length of 5.

The second figure has 8 tiles

The third figure has 15 tiles

The 4th figure has 24 tiles

The 5th figure has 35 tiles
