3. Explain why the polynomial 34 + 5x3 - 7x2 + 3x has a degree 3 and not 4.
Answer:
See explanation below
Step-by-step explanation:
The degree of a polynomial is the LARGEST power at which the variable/s appear in their expression.
Notice that in the given polynomial, the highest power for the variable x is 3, from the term 5 x^3.
There is no other term with higher power for x.
The variable appear in the expression [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] x which has highest power 3 not 4 .
We have to explain, why the polynomial [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] has a degree 3 and not 4.
According to the question,
A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.
The degree of a polynomial is the largest power at which the variable appear in their expression.
[tex]Polynomial = 3^{4} + 5x^{3} + 7x^{2} + 3x[/tex]
The given polynomial, the highest power for the variable x is 3, from 5 .
Hence, The variable appear in the expression [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] x which has highest power 3 not 4 .

I need help with this what is the awnser
Answer:
x = 23
Step-by-step explanation:
For this figure, we know we are dealing with a 90 degree angle since there is a small square in the figure, therefore we can set up the equation...
65 + (x + 2) = 90
In this sense, the parenthesis are unnecessary.
67 + x = 90
-67 -67
x = 23

Step-by-step explanation:
Slope = change in y/change in x
Choose any two points that are on the line, find the difference between the y and the difference between the x, and set as a fraction.
In this case, we can use (0,0) and (1,1) since both points are on the line.
Difference in y: 1 - 0 = 1
Difference in x: 1 - 0 = 1
Write as a fraction: 1/1

Which one of the points A(5.2). B(6,-3) and C(4.7) is the mid-point of the other two? Check your answer by calculating two distances.
Answer:
A is the midpoint
Step-by-step explanation:
Given
A(5.2) B(6,-3) and C(4.7)
Required
Which is the midpoint
Midpoint is calculated using:
[tex](x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]
Testing A as the midpoint, we have:
[tex](5,2) = \frac{1}{2}(6+4,-3+7)[/tex]
[tex](5,2) = \frac{1}{2}(10,4)[/tex]
[tex](5,2) = (\frac{1}{2}*10,\frac{1}{2}*4)[/tex]
[tex](5,2) = (5,2)[/tex]
The above equation is true. Hence, A is the midpoint of B and C
Given f(x) = x^2 + 3 , work out the value of f(4)
Answer: 19
Step-by-step explanation:
[tex]f(4)=(4)^2+3=16+3=19[/tex]
Answer:
f(4) = 19
Step-by-step explanation:
f(x) = x^2 + 3
plug in 4 for the xs
f(4) = 4^2 + 3
f(4) = 16 + 3
f(4) = 19
The Jackson family is driving from Boston to New York for a summer vacation trip. So far, they have driven 84 miles which is 40% of the total miles of their trip. How many total miles is the Jackson’s trip from Boston to New York?
The answer you are looking for is 210 miles.
To find this answer you must first make 40% into a decimal. To do so, simply divide 40 by 100. This will give you 0.4.
Next, you divide 84 by 0.4. You divide because the percentage of a number is found by multiplying said number by the decimal form of the percent. Since we arent looking for the percentage of a number, but rather the number from which the percentage came, we do the opposite operation.
84 ÷ 0.4 = 210. Thus meaning 210 miles is your answer.
I hope this helps!
The total number of miles that Jackson’s trip from Boston to New York will be 210 miles.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
The Jackson family is driving from Boston to New York for a summer vacation trip. So far, they have driven 84 miles which are 40% of the total miles of their trip.
Let x be the total number of miles. Then the equation is given as,
0.40x = 84
Simplify the equation, then we have
x = 84 / 0.40
x = 210 miles
The total number of miles that Jackson’s trip from Boston to New York will be 210 miles.

what number must you add to complete the square?
x^2+14x=3
Answer: 49
Step-by-step explanation: In order to complete the square, you need a perfect square trinomial on the left side of the equation.
The question is, what is the number we need?
Well it comes from a formula. The number that is added to both sides
comes from half the coefficient of the middle term squared.
So that's half of 14 which is 7, squared which is 49.
Find the value of given trigonometric function cot (-330°)
Answer:
The exact value should be
[tex] \sqrt{3} [/tex]
Step-by-step explanation:
Though you can get this directly out from your calculator, but you can utilize the opposite angle identities, cot(-
θ)=-cot θ, then use the trig identity, which is
[tex] \cot(θ) = \frac{ \cos(θ) }{ \sin(θ) } [/tex]
So cot (-330)=cos (-330)/sin (-330)
