Help quick! What is the name (monomial, binomial, trinomial, polynomial?), degree, coefficient, constant?!

Answer:

-5=x

Step-by-step explanation:

3=-2 (x+2)

-2 (x+2) = -2x-4

3=-2x-4

-4 from 3 and -4

= -7=-2x

do the opposite "-2 to +2 "

=-5=x

The lengths of the sides that could be for a 45°-45°-90° triangle are 3, 4, 5

A triangle is a three-sided polygon that consists of three edges and three vertices.

The lengths of the sides of a 45°-45°-90° triangle have a specific relationship.

In such a triangle, the ratio of the lengths of the sides is 1:1:√2.

√3/2, √3/2, √2

The ratio of the lengths is √3/2 : √3/2 : √2.

This does not match the 1:1:√2 ratio, so it is not a valid option.

3√2, 3√2, 6

The ratio of the lengths is 3√2 : 3√2 : 6.

This does not match the 1:1:√2 ratio, so it is not a valid option.

√3, 3, 2√3

The ratio of the lengths is √3 : 3 : 2√3. This does not match the 1:1:√2 ratio, so it is not a valid option.

3, 4, 5

The ratio of the lengths is 3 : 4 : 5.

This does match the 1:1:√2 ratio, so it is a valid option.

Therefore, the lengths of the sides that could be for a 45°-45°-90° triangle are 3, 4, 5.

Answer:

125°

Step-by-step explanation:

So we know that the total height is 85.5 (building height plus Lucia's height) and that the distance between Lucia and the fountain is 122ft away. As seen in the badly drawn picture below, the question asks us to solve for x, we can do this by first solving for y by using tangent to calculate its value which is the following

tan(y) = opposite / adjacent

tan(y) = 122 / 85.5

tan(y) = 1.4269

y = [tex]tan^{-1}[/tex](1.4269)

y = 54.97

Now that we have the value of y and we know that a straight line has a degree of 180, we can simply subtract the degree of y from 180 to get the degree of x

180 - 54.97 = 125.03

Answer:

about 35°

Step-by-step explanation:

tan^-1(85.5/122)

Answer:

Concert Specialties is the better buy

Step-by-step explanation:

In order to determine which of the two deals is the better buy, we first need to find out how many of each pack we would need to get the needed 12 tickets. Once we have this value we multiply it by the dollar amount of each pack and compare the totals like so...

Concert Specialties => pack of 3 * 4 = 12 tickets => 4 * 75 = $300

We 'R' Entertainment => pack of 4 * 3 = 12 tickets => 3 * 108 = $324

Therefore, we can now see that the Concert Specialties is the better buy since you are getting the 12 tickets for $24 less than We 'R' Entertainment

Correctly arranged question is;

Rita is playing a game by rolling a rectangular prism made up of cubes. The prism is 6 cubes wide, 3 cubes high, and 4 cubes deep. Rita rolls the cube and says that the top view is a 6-unit by 4-unit rectangle.

Which statement explains whether Rita could be correct?

A) Rita could be correct because the cube could land so the 3-cube height and the 4-cube depth make up the top face of the cube.

B) Rita could be correct because the cube could land so the 6-cube width and the 4-cube depth make up the top face of the cube.

C) Rita could not be correct because the top face of the cube is made up of the 6-cube width and the 4-cube depth.

D) Rita could not be correct because the top face of the cube is made up of the 6-cube width and the 3-cube height.

Answer:

Option B: Rita could be correct because the cube could land so the 6-cube width and the 4-cube depth make up the top face of the cube.

Step-by-step explanation:

We are told the dimensions of the prism are;

Width = 6 cubes wide

Height = 3 cubes high

Depth = 4 cubes deep.

We are further told that when she rolls that the top view is a 6-unit by 4-unit

For the top view to be 6 unit x 4 unit, it means that the top face is showing the width and depth sides from the dimensions we were earlier given.

Therefore, from the options given, the only one that depicts what I just explained is Option B which says:

The cube could land in such a way that the top face is made up of the 6-cube width and the 4-cube depth

Answer:

-2

Step-by-step explanation:

its -2 cuz to find the slope the equation is the second y - the first y over the second x - the first x so -5 - 5 is 10 over 3 - -2 is 5 so it would be -10/5 which simplifies to -2

Answer:

y= 3x-1

Step-by-step explanation:

Use two points from the line to find slope. I'm using (1,2) and (2,5)

Put these values into slope formula and get 5-2/2-1 which simplifies to 3. So slope is 3.

Next, for the y-intercept. If you look closely, the line intercepts the y-axis at (0,-1), so our y-intercept is -1.

Put the equation together to get y=3x-1

Answer:

5(x-3)

Step-by-step explanation:

The word "SUM" means the answer to an "ADDITION".

"SUM" is always used with the word "AND" to indicate which numbers are being added.

The SUM of a number AND -3 is written as:  

( x + ( − 3 ) ), or  ( x -3 )

(where we have chosen the number to be  x .)

But we want FIVE of those sums; this means:

5  ( x − 3 )

Answer:

Step-by-step explanation:

If the impedance is related to the voltage and the current by the formula V = IZ where;

V is the voltage

I is the current

Z is the impedance

Given

I = 0.4+3i

V = 0.3-2i

Voltage V = (0.4+3i)(0.3-2i)

V = 0.4(0.3)-0.8i+0.9i-6i²

V = 0.12+0.1i -6i²

Since i² = -1

V = 0.12+0.1i-6(-1)

V = 0.12+0.1i+6

V = 6.12+0.1i.

Hence the impedance is 6.12+0.1i

Answer:

[tex]y=-\frac{7}{2}x+8[/tex]

Step-by-step explanation:

Given the equation

[tex]y\:=\:\frac{2}{7}x+9[/tex]

comparing the equation with the slope-intercept form

[tex]y =mx+b[/tex]            

Here,

so the slope of the line is 2/7

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

the slope of the perpendicular line will be: -7/2

Therefore, the point-slope form of the equation of the perpendicular line that goes through (4,-6) is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-6\right)=\frac{-7}{2}\left(x-4\right)[/tex]

[tex]y+6=\frac{-7}{2}\left(x-4\right)[/tex]

[tex]y+6-6=\frac{-7}{2}\left(x-4\right)-6[/tex]

[tex]y=-\frac{7}{2}x+8[/tex]
