Answer:

Yes it is a polynomial.

It is a trinomial.

The degree is 4.

Step-by-step explanation:

So polynomial is an expression that has variables, constants, and exponents. And all of these are connected through things like addition and subtraction. In this question, you have x as your variable, 0 as your constant, and 4,3,1 as your exponents.

A term is the part of the polynomial that is separated by + or - sign. So in this question, you have 5m^3, -3m^4, and -7m as your terms. Because you have three terms, therefore this is a trinomial.

The degree of polynomial is represented by the variable with the largest exponent, so in your case, 4 is your largest exponent, therefore the degree of the polynomial is 4.

Answer:

The horizontal length is 80 cm, and the vertical height is 60 cm.

Step-by-step explanation:

The aspect ratio is the ratio of the horizontal length to the vertical height.

We have a rectangle with sides 4 and 3. We can find the length of the diagonal.

We can use the Pythagorean theorem to find the length of the diagonal.

a^2 + b^2 = c^2

3^2 + 4^2 = c^2

9 + 16 = c^2

c^2 = 25

c = 5

The diagonal is 5 in the ratio.

The ratio of the horizontal length to the vertical height to the diagonal is

4:3:5

We multiply all the numbers in the ratio by the same unknown, x.

A ratio of 4:3:5 is the same as a ratio of 4x:3x:5x.

We are told that the diagonal is 100 cm, so we have

4x : 3x : 100,

but we already had a ratio of

4x : 3x : 5x, so

5x = 100, and we can find x.

5x = 100

Divide both sides by 5.

x = 20

Since x = 20, then the horizontal length 4x = 4(20) = 80,

and the vertical height 3x = 3(20) = 60

Answer: The horizontal length is 80 cm, and the vertical height is 60 cm.

Answer:

horizontal length=80, vertical length=60

Step-by-step explanation:

a^2 + b^2 = c^2

the tv is a 3:4:5 right triangle

the ratio is then changed from

3:4:5

to

60:80:100

because 100/5 = 20

so you multiply the original ratio by 20

(because the length of 100 that we are given is the hypotenuse of the triangle(diagonal of the tv))

Therefore,

the horizontal length is 80

the vertical lengt is 60

Answer:

3(x+2)=12

Step-by-step explanation:

Ok, so this is simple. First you multiply the three on the outside by the x and 2 on the inside using the distributive property. Then you should get 3x (3 times x) + 6 (3 times 2). now that you have 3x+6=12, you can subtract the 6 from both sides. you should end up with 3x=6. To figure out x you should divide both sides by 3. You should end with x = 2.

3(x+2)=12

3x+6=12

3x=6

x=2

Answer:

A= 2

B= -1

Step-by-step explanation:

Do rise over run but make sure B is negative as it is going downwards

Answer:

A= 2 B= 9/10 (0.9)

Step-by-step explanation:

to find the gradients, we need to use the formula:

rise / run ---> which is basically counting the "boxes" in both of the x and y axis and divide them together (rise=y, run=x)

like that

A:

x axis=5    y=10 ---> then we use the formula (rise/run) 10/5= 2

B

x axis=10    y=9 ---> then we use the formula (rise/run) 9/10= 0.9

but since B is going downhill, it'll be -0.9

Answer:

(-7,4]

Step-by-step explanation:

I'm going to assume that you need this in interval form

The domain is just asking for all the possible x values

The x value that's furthest to the left is -7 and because it's an open circle we write ( instead of [

the furthest to the right the line goes is 4 and because the circle is closed it's written with ]

but it all together and get

(-7,4]

Answer:

b = 0

Step-by-step explanation:

Let's solve your equation step-by-step.

−10b+5=7b+5

Step 1: Subtract 7b from both sides.

−10b+5−7b=7b+5−7b

−17b+5=5

Step 2: Subtract 5 from both sides.

−17b+5−5=5−5

−17b=0

Step 3: Divide both sides by -17.

−175/17 = 0/-17

0

Step-by-step explanation:

Answer:

[tex]y = 10+ 0.50 x[/tex]

Step-by-step explanation:

Given

[tex]Initial = \$10[/tex]

[tex]Increment = \$0.50[/tex] -- yearly

Required

Represent as a function (this is the missing part of the question)

The given details show that the question illustrates linear function

i.e.

[tex]y = b + mx[/tex]

In this case, it is:

[tex]Current\ Rate = Initial + Increment * Years[/tex]

Represent the current rate with y and the years with x.

So, we have:

[tex]y = Initial + Increment * x[/tex]

Substitute 10 for Initial and 0.5 for Increment

[tex]y = 10+ 0.50 * x[/tex]

[tex]y = 10+ 0.50 x[/tex]

Step-by-step explanation:

Answer:

78.5inches²

Step-by-step explanation:

area of a circle is pie r²

so to get the radius you half the diameter

and then u do pie×5²

or 25pie which is 78.5 (rounded to 1dp)

Answer:

A.)555 in.^2

Step-by-step explanation:

When solving these types of things, I usually like to cut it up into smaller, easier to manage shapes.

You can cut that trapezoid into two triangles and one rectangle.

Since both triangles are the same size, you don't need to divide the base and height by two, so you'll get the area of both triangles combined (which saves some work).

We know the length of the rectangle and bases of the triangle combined is 44 inches, and that the length of just the rectangle is 30 inches, so we can just subtract 30 from 44 and divide it by two for the base of a triangle.

                                                     44 - 30 = 14

                                                     14/2 = 7

Now that we filled in the information not listed, we can finally solve:

The base of one triangle is 7 inches, and the height is 15 inches.

Now, we just multiple and divide it by 2 for one triangle (it would be 52.5 inches).

But, we don't need to divide it by two because both triangles are the same size, so we can just get the sum of the area of both triangles combined by skipping that step (because triangles are half a square and two of those triangles make a full square).

7 x 15 = 105

The area of both triangles combined: 105 in.^2

Next, we need to solve the area of the rectangle. This is easy considering all you have to do is multiply 15 by 30 (length times width).

15 x 30 = 450

The area of the rectangle: 450 in.^2

Now, the final step. Addition. All you need to do is add up all the sums, and you're done.

450 + 105 = 555

The area of entire figure: 555 in.^2

NOTE: the symbol '^' represents exponents, so when you see 555 in.^2, it means inches squared (or to the power of 2)

Answer:

The 24

Step-by-step explanation:

The 30 represents how many problems there were in all

Hope I was Helpful!!

Ohhhhh No wait the answer is . 80 Im so sorry

B. 0.80

So, 24 out of 30 is equal to 80%.

If 100% = 1.0

Then 80% = 0.80

Hope this helps you out! Good luck. :)

Answer:

160

Step-by-step explanation:

Answer:

34

Step-by-step explanation:

plug the coefficients in the equation, so

-2-2(-2)(-5)+56

Distribute the -2(-2)(-5), so it equals -20

so the equation is -2-20+56

add -20+56, so -2+36

-2+36=34

34 is your answer
