Write a polynomial that is a trinomial, has the coefficients 3 and 4, the variable x,
and the constant 7
Answer:
3x+4x+7
Step-by-step explanation:
First, a Trinomial consists of three terms.
so we have blank+blank+blank
Next we need to add the coefficients.
3+4+blank
Add the variables.
3x+4x+blank
And lastly, add the constant.
3x+4x+7
Good luck!
A trinomial that meets the given criteria is:
p(x) = 3*x^2 + 4*x + 7
How to get a trinomial?
A trinomial is a polynomial with 3 terms, we can write it as:
p(x) = A*x^n + B*x^k + C*x^m
Where n, k, and m, can be only natural numbers equal to or larger than zero, and A, B, and C are the coefficients.
First, we know that our trinomial has a constant 7, then one of the exponents must be 0, let's say that m = 0, then C = 7.
p(x) = A*x^n + B*x^k + 7
Now, we know that the other coefficients must be 3 and 4, so we can use:
A = 3B = 4And there are no more restrictions, so we can use any values for n and k, I will use:
n = 2k = 1.Then the trinomial becomes:
p(x) = 3*x^2 + 4*x + 7

Which of the following is the equation of the graphed circle? answers: 1) (x + 2)2 + (y – 3)2 = 25 2) (x – 2)2 + (y + 3)2 = 25 3) (x – 2)2 + (y + 3)2 = 5 4) (x + 2)2 + (y – 3)2 = 5
Answer:
( x - 2)^2 + ( y +3) ^2 = 25
Step-by-step explanation:
The center is at (2,-3) and the radius is 5 units
A circle can be written as
( x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
( x - 2)^2 + ( y - -3) ^2 = 5^2
( x - 2)^2 + ( y +3) ^2 = 25
There are about 3.5725 * 10^4 grains of sand in an 8-ounce cup. Based on this, about how many grains of sand would there be in a 5-gallon container (note: 1 gallon = 16 cups). Write the result in scientific notation.
Answer:
[tex]3.5725 * 10^5[/tex]
Step-by-step explanation:
Given
There are about 3.5725 * 10^4 grains of sand in an 8-ounce cup.
Required
How many grains of sand would there be in a 5-gallon container?
Let x represent the number of grains in 5 gallon; So, From the question, we have that;
8 cups = 3.5725 * 10^4
5 gallon = x
Cross Multiply
x * 8 cups = 5 gallon * 3.5725 * 10^4
Recall that 1 gallon = 16 cups
[tex]x * 8\ cups = 5 * 16\ cups * 3.5725 * 10^4[/tex]
[tex]x * 8 = 5 * 16 * 3.5725 * 10^4[/tex]
Divide both sides by 8
[tex]\frac{x * 8}{8} = \frac{5 * 16 * 3.5725 * 10^4}{8}[/tex]
[tex]x = \frac{5 * 16 * 3.5725 * 10^4}{8}[/tex]
[tex]x = 5 * 2 * 3.5725 * 10^4[/tex]
[tex]x = 10 * 3.5725 * 10^4[/tex]
[tex]x = 3.5725 * 10^5[/tex]
Hence, the number of grains of sand in 5 gallon is [tex]3.5725 * 10^5[/tex]

What is the value of s?
Answer:
s = 4
Step-by-step explanation:
x is a supplementary angle or 3d angle of the triangle.
(33s - 38) + x = 180 as supplementary angles.
(4s + 43 )+ 35 + x = 180 as angles of the triangle.
(33s - 38) + x = (4s + 43 )+ 35 +x
33s - 38 = 4s + 43 + 35
33s - 4s = 43 + 35 + 38
29s = 116
s = 4
The negative reciprocal of -5/8 is: A. -5/8 B. 5/8 C. 8/5 D. -8/5
Answer:
+ 8/5
Step-by-step explanation:
Reciprocal is flip
Take the negative flip
- ( - 1 /(5/8))
+ 8/5
Answer:
8/5
Step-by-step explanation:
The reciprocal of a number is 1/that number.
So, the reciprocal of -5/8 is [tex]1/\frac{-5}{8}[/tex]= 1 times 8/-5
8/-5 is the reciprocal of -5/8.
However, we are looking for the negative reciprocal.
So, multiply the number by negative 1.
[tex]\frac{8}{-5} (\frac{-1}{1}[/tex]) = [tex]\frac{-8}{-5}[/tex] = [tex]\frac{8}{5}[/tex]

How many times will the digit '1' appear if we write all whole numbers from 1 to 99?
Answer:
20 times
Step-by-step explanation:
The digit 1 appear in number from 1 to 99 is 20 times
19 times will the digit '1' appear if we write all whole numbers from 1 to 99.
To determine the digit '1' appear if we write all whole numbers from 1 to 99?
From 1 to 9, there is one 1.
From 10 to 19, there are ten 10.
From 20 to 29, there is one 1.
From 30 to 39, there is one 1.
From 40 to 49, there is one 1.
From 50 to 59, there are ten 1.
From 60 to 69, there is one 1.
From 70 to 79, there is one 1.
From 80 to 89, there is one 1.
From 90 to 99, there is one 1.
So the total number of 1s is 1 + 10 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 19.
Therefore, 19 times will the digit '1' appear if we write all whole numbers from 1 to 99.

Consider the function y=x^2+5x-2 . What would happen to the graph if (x -1) was substituted in place of the x?
Answer:
B.
Step-by-step explanation:
f(x - c) shift the function c units to the right.
In this case, if (x - 1) was substituted in place of the x, the graph would shift 1 unit to the right.
If you want to graph the new function and know the graph of the previous one, this relationship avoids you the substitution of (x - 1) into the function and expansion of the expression to obtain a new quadratic formula.

Simplify (7x2− 2x + 9) + (3x2+ 15x − 4)
Answer:
10x^2+13x+5
Step-by-step explanation:
(7x^2− 2x + 9) + (3x^2+ 15x − 4)
Combine like terms
(7x^2+3x^2− 2x+ 15x + 9 − 4)
10x^2+13x+5
Answer:
[tex]10x^{2} + 13x + 5[/tex]
Step-by-step explanation:
In this equation, you need to add all the like terms. For example, 7x² and 3x² are like terms, since they both are being squared.
First find the like terms:
7x² + 3x²
-2x + 15x
9 - 4
Now simplify the above equations.
7x² and 3x² is equal to 10x². You only have to add the whole number, the exponent stays the same.
-2x + 15x is equal to 13x. Since -2 is negative, you can simply take away two from 15, which is 13, making it 13x.
9 - 4 is equal to 5.
Now add everything together.
[tex]10x^{2} + 13x + 5[/tex]
Your answer is 10x² + 13x + 5.

Answer:
t and u are parallel lines
s and t are also parallel lines
Step-by-step explanation:
If two parallel lines are cut by a transversal ,
then in it
pair of alternate angle are equals, similarly vice versa
if pair of alternate angle are equals then lines are parallel
pair of corresponding angles are equal and vice-versa
for example
in the given problem
if line t and u are parallel (note we have assumed this to give example of parallel lines)
then angle 7 and 9 are called alternate angles
pair of angles 5 and 9 are corresponding angles.
________________________________________________
given
∠8 = ∠10 which are alternate angles for line t and u and s is transversal for it,
thus t and u are parallel lines
___________________________
∠1 = ∠3 as they vertically opposite angles
and we know that pair of vertically opposite angles are equal
given
∠1 = ∠7
thus
∠3 = ∠7
as pair of angles ∠3 and ∠7 are corresponding angles. and are equal and hence line s and t are also parallel.

Consider the system of equations given in slope-intercept form. y = −13x + 17, y = 5x - 23 The solution seems to be about (8, 14). Use the graphing calculator to find the exact values for the intersection point. What is the solution to this system of equations?
The exact values for the intersection point is (20/9, -107/9)
Given the system of equation expressed as;
y = −13x + 17;
y = 5x - 23
Since they are both y-values, we will equate both expressions to have:
-13x + 17 = 5x - 23
-13x - 5x = -23 - 17
-18x = -40
x = 40/18
x = 20/9
Substitute x = 20/9 into equation 2:
y = 5x - 23
y = 5(20/9) - 23
y = 100/9 - 23
y = -107/9
Hence the exact values for the intersection point is (20/9, -107/9)

Answer:
[tex]X = \begin{bmatrix}1&3\\ 2&4\end{bmatrix}[/tex]
Step-by-step explanation:
The question we have at hand is, in other words,
[tex]\begin{bmatrix}4&2\\ \:1&1\end{bmatrix}\left(X\right)=\begin{bmatrix}8&20\\ \:3&7\end{bmatrix}[/tex] - where we have to solve for the value of [tex]X[/tex]
If we have to isolate [tex]X[/tex] here, then we would have to take the inverse of the following matrix ...
[tex]\begin{bmatrix}4&2\\ \:1&1\end{bmatrix}[/tex] ... so that it should be as follows ... [tex]\begin{bmatrix}4&2\\ \:1&1\end{bmatrix}^{-1}[/tex]
Therefore, we can conclude that the equation as to solve for " [tex]X[/tex] " will be the following,
[tex]X=\begin{bmatrix}4&2\\ 1&1\end{bmatrix}^{-1}\begin{bmatrix}8&20\\ 3&7\end{bmatrix}[/tex] - First find the 2 x 2 matrix inverse of the first portion,
[tex]\begin{bmatrix}4&2\\ 1&1\end{bmatrix}^{-1}[/tex] = [tex]\frac{1}{\det \begin{pmatrix}4&2\\ 1&1\end{pmatrix}}\begin{pmatrix}1&-2\\ -1&4\end{pmatrix}[/tex]= [tex]\frac{1}{2}\begin{bmatrix}1&-2\\ -1&4\end{bmatrix}[/tex] = [tex]\begin{bmatrix}\frac{1}{2}&-1\\ -\frac{1}{2}&2\end{bmatrix}[/tex]
At this point we have to multiply the rows of the first matrix by the rows of the second matrix,
[tex]X = \begin{bmatrix}\frac{1}{2}&-1\\ -\frac{1}{2}&2\end{bmatrix}\begin{bmatrix}8&20\\ 3&7\end{bmatrix}[/tex] ,
[tex]X = \begin{pmatrix}\frac{1}{2}\cdot \:8+\left(-1\right)\cdot \:3&\frac{1}{2}\cdot \:20+\left(-1\right)\cdot \:7\\ \left(-\frac{1}{2}\right)\cdot \:8+2\cdot \:3&\left(-\frac{1}{2}\right)\cdot \:20+2\cdot \:7\end{pmatrix}[/tex] - Simplifying this, we should get ...
[tex]\begin{bmatrix}1&3\\ 2&4\end{bmatrix}[/tex] ... which is our solution.
