Answer:
The sum of the two equation is [tex]x^5 + x^4 + 7x^2 + x -2[/tex]
Step-by-step explanation:
The given two equations are
[tex](x^5 - 2x^4 + 3x^2 - 6)\\ (3x^4 + 4x^2 + x + 4)[/tex]
Now rearranging the two equation in such a way that variables with similar with same power are grouped together -
[tex]x^5 - 2x^4 + 3x^4 + 3x^2 + 4x^2 + x- 6+ 4\\x^5 + x^4 (3-2) + x^2 (3+4) + x -6+4\\x^5 + x^4 + 7x^2 + x -2[/tex]

What is the root when talking about a quadratic equation
Answers
The root is the x intercepts or the zeros of the problem
If I were to graph
(x-5)(x+4)=0
We need a number for x which makes this equation 0
The numbers are 5 or -4
These are the x intercepts of the parabola or roots
Answer:
The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

Devon’s tennis coach says that 72% of Devon’s serves are good serves. Devon thinks he has a higher proportion of good serves. To test this, 50 of his serves are randomly selected and 42 of them are good. To determine if these data provide convincing evidence that the proportion of Devon’s serves that are good is greater than 72%, 100 trials of a simulation are conducted. Devon’s hypotheses are: H0: p = 72% and Ha: p > 72%, where p = the true proportion of Devon’s serves that are good. Based on the results of the simulation, the estimated P-value is 0.06.

The funnel is filled with oil. How many quarts of oil are in the funnel? 3 1 qt 58 in. Round your answer to the nearest tenth.
Answers
Answer:
There is 2.887 quarts of oil in the funnel
Step-by-step explanation:
Complete question
A funnel is in the shape of a cone with a radius of 4 inches and a height of
10 inches. The funnel is filled with oil. How many quarts of oil are in the funnel?
Solution
As we know, volume of the cone is given by
[tex]V = \frac{1}{3} \pi r^2 h[/tex]
Here,
V = volume of the cone
r is the radius of the base of the cone
h is the height of the cone
Substituting the given values in above equation, we get -
[tex]V = \frac{1}{3} *3.14*4*4*10\\V = 167.467[/tex] Cubic inch
As given
1 quarts = 58 cubic inch
Total number of quarts of oil
[tex]\frac{167.467}{58} \\2.887[/tex]
There is 2.887 quarts of oil in the funnel

2) A block of cheese weighs 0.6 kg. The block is cut into smaller pieces. Each piece weighs 0.05 kg. How many pieces are there? (Show the division equation to solve for this word problem before showing multiplication to solve.)
Answers
Answer:
12
0.6/0.05
(0.6 x 100) / (0.05 x 100)
= 60/5 = 12
Step-by-step explanation:
number of pieces = total weight of the cheese / weight of each piece
0.6 / 0.05
to divide easily, convert the decimals to whole number by multiply both the denominator and numerator by 100
(0.6 x 100) / (0.05 x 100)
= 60/5 = 12
A video game originally costs $63, but if you buy it before the end of May there is a 25% off sale. The sales tax is 9.5%. What is the final price of the video game if you buy it before the end of May?
Answers
Answer: $53.24
Step-by-step explanation:
Find the sales tax:
9.5*63.00=598.5
Then divide 598.5 by 100: 598.5/100= 5.985
Round: $5.99 ( sale tax amount )
Now we find the discount: 25*63.00= 1,575
Then divide it by 100 : 1,575/100= $15.75 ( discount amount )
Take the original price of the game and subtract it by the discount amount, then add the sales tax amount: 63.00-15.75= 47.25+5.99= $53.24
Answer: $53.24
