Answer:
1. Find the intercepts.
2. Check for symmetry. If the function is an even function, its graph is symmetric with respect to the y-axis, that is, f(–x) = f(x).
If a function is an odd function, its graph is symmetric with respect to the origin, that is, f(–x) = –f(x).
3. Use the multiplicities of the zeros to determine the behavior of the polynomial at the x-intercepts.
4. Determine the end behavior by examining the leading term.
5. Use the end behavior and the behavior at the intercepts to sketch the graph.
6. Ensure that the number of turning points does not exceed one less than the degree of the polynomial.
7. Optionally, use technology to check the graph.

If 20% of a number is 28 and 25% of the same number is 35, find 45% of that number.If 7% of a number equals 9, find 70% of that number.
Answer:
Step-by-step explanation:
Let the number be 'x'
20% * x = 28
[tex]\dfrac{20}{100}*x = 28\\\\\\\dfrac{1}{5}*x=28\\\\\\x=28*5\\\\x = 140[/tex]
[tex]\dfrac{45}{100}*140=9*7=63[/tex]
45% of 140 = 63
2)
[tex]\dfrac{7}{100}*y=9\\\\y=9*\dfrac{100}{7}=\dfrac{900}{7}=128.57[/tex]
[tex]\dfrac{70}{100}*128.57= 90[/tex]

It's kind-of blurry, can you copy-paste the questions?
Step-by-step explanation:
In a two digits number the sum of the digit is 8. The difference this number and the number with the digits reversed is 54. What is the number?
b#~8=+/"1 sep b=.a#~54=|a-10#.|."1 sep a=.10 to 99
17 71
Alternately:
10#.b#~(8=+/"1 b)*.54=|a-10#.|."1 b=.sep a=. 10 to 99
17 71
The answer is 71.
71 - 17 = 54.

Step-by-step explanation:
Mid-Segment of a triangle is always parallel to the third side, and the length of the midsegment is half the length of the third side.
(x₁,y₁) (x₂,y₂) (x₃,y₃): A(-10,30), B(30,50, C(-40,20)
XY = 1/2 AC , YZ = 1/2 AB , ZX = 1/2 BC
X (10,40) , Y (-5,35) , Z (-25,25) : X(x'₁,y'₁), Y(x'₂,y'₂), Z(x'₃,y'₃)
area of triangle by 3 vertices: (x₁,y₁) (x₂,y₂) (x₃,y₃) is
a = abs[x₁(y₂-y₃)+x₂(y₃-y₁)+x₃(y₁-y₂)] / 2 ... this is just a common formula for any triangle
a = abs(-10*30 + 30*-10 + -40*-20) / 2 = 100
a' = abs(10*10 + -5*-15 + -25*5) / 2 = 25
a/a' = 100/25 = 4/1
thankyou for all help
Answer:
The question is not clear the picture is cut off
Step-by-step explanation:
A tractor can plant a field at a rate of 2.5 acres per 5 minutes. If a mammoth farm measuring 4 square miles needs planting, how long will it take in hours to plant the field? There are 640 acres in a square mile. Determine your answer to the nearest hour. If the tractor can run 8 hours a day, what is the minimum number of days it will take to plant the farm?
The time taken by the tractor to plant the field with an area of 4 square miles is nearly 85 hours.
The minimum number of days taken by the tractor when working 8 hours a day is 11 days.
What is the area?The area is the total surface occupied within the boundary of the figure.
How to solve the question?In the question, we are given that a tractor can plant a field at a rate of 2.5 acres per 5 minutes.
We are asked the time taken by the tractor to plant a field having an area of 4 square miles.
First, we convert the area of the field from sq. miles to acres using the conversion rate, 1 square mile = 640 acres,
Thus, the area of the field = 4 sq. miles = 4*640 acres = 2560 acres.
Time taken to plant 2.5 acres is given to be 5 minutes.
Thus, the time taken to plan 1 acre = 5/2.5 = 2 minutes.
Thus, the time taken to plant the field having an area of 2560 acres = 2560*2 minutes = 5120 minutes = 85.33 hours = 85 hours and 20 minutes.
Thus, the time taken by the tractor to plant the field with an area of 4 square miles is nearly 85 hours.
The time for which the tractor can run daily is 8 hours.
Thus, the number of days taken by the tractor to plant the field = 85.33/8 = 10.66625, or 11 days.
Thus, the minimum number of days taken by the tractor when working 8 hours a day is 11 days.

Answer:
Ali is 72%
Zain is 64%
Ahmed scored 73%
So Ahmed Scored more
Step-by-step explanation:
Answer:
Ahmed
Step-by-step explanation:
Ali scored 18 out of 25. 18/25 = 0.72. 0.72 as a percentage is 72%
Same with Zain, but he he scored like around a 64. So the highest one would be Ahmed.
The distance between the points P(1,3) and Q(x,7) is 5 units. Find the possible values of x.
Answer:
x = - 2 , x = 4
Step-by-step explanation:
Calculate the distance PQ using the distance formula and equate to 5
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = P (1, 3) and (x₂, y₂ ) = Q (x, 7 )
PQ = [tex]\sqrt{(x-1)^2+(7-3)^2}[/tex] = [tex]\sqrt{(x-1)^2+4^2}[/tex] = [tex]\sqrt{(x-1)^2+16}[/tex] , then
[tex]\sqrt{(x-1)^2+16}[/tex] = 5 ( square both sides )
(x - 1)² + 16 = 25 ( subtract 16 from both sides )
(x - 1)² = 9 ( take square root of both sides )
x - 1 = ± [tex]\sqrt{9}[/tex] = ± 3 ( add 1 to both sides )
x = 1 ± 3
Then
x = 1 - 3 = - 2 , or
x = 1 + 3 = 4

1) quotient of 32 and 4 is 32/4
8 more than means + 8
so 32÷4 + 8
2) quotient of 12 and 6 is 12/6
8 more than means + 8
so 12÷6 + 8
3) 7 * 4 + 3
here multiplication gets preference
so it is (7*4) + 3
3 more than the product of 7 and 4
4) 35 ÷ (12 - 5)
here parentheses gets preference
so it can be called as
