A function f(x) = x^2 - 4 has a domain as the set of integers
of from 1 through 10, inclusive (including 1 and 10). For
how many values of x is f(x) positive?
Answer:
8
Step-by-step explanation:
f(x) = (x+2)(x-2)
Substituting x=1 into f(x):
f(1) = 3*-1
= -3
Since -2 & 2 touch the x-axis, 1 has a negative y value, 2 has a y value of 0, and all values from 2, are positive.
Hence,
3, 4, 5, 6, 7, 8, 9, 10 are all positive. Therefore, the answer is 8
This can be confirmed with a graph, as attached below.

simplify each radical, then add or subtract. sqrt12 +sqrt27
Answer:
[tex]5\sqrt{3}[/tex]
Step-by-step explanation:
simplify sqrt(12): [tex]\sqrt{12} = \sqrt{4 * 3} = \sqrt{4} * \sqrt{3} = 2 * \sqrt{3} = 2\sqrt{3}[/tex]
simplify sqrt(27): [tex]\sqrt{27} = \sqrt{9 * 3} = \sqrt{9} * \sqrt{3} = 3 * \sqrt{3} = 3\sqrt{3}[/tex]
substitute into original equation: [tex]\sqrt{12} + \sqrt{27} = 2\sqrt{3} + 3\sqrt{3}[/tex]
factor out sqrt(3): [tex]\sqrt{3} * (2 + 3)[/tex]
simplify: [tex]\sqrt{3} * 5 = 5\sqrt{3}[/tex]
Paul mixes nuts worth $1.40 per pound with oats worth $1.70 per pound to get 30 pounds of trail mix worth $1.50 per pound. How many pounds of nuts and how many pounds of oats did he use?
Paul used pounds of nuts and pounds of oats.
The quantity of pounds of nuts and oats used by Paul is 20 and 10 pounds respectively.
According to the question:
Let pounds of nuts used = x Let pounds of oats used = yTotal quantity of trail mix used = 30 pounds and Overall cost of trail mix = 30 × 1.50 = $45.The information above can be used to generate two equations as follows;
1.4x + 1.7y = 45.............eqn(1)x + y = 30.......................eqn(2)Consequently, by solving the equations simultaneously; we have;
Pounds of nuts, x = 20 pounds.Pounds of oats, y = 10 pounds.Read more:

Jamal is using the distance formula to find the length, d, of the line segment. His work so far is shown. What is Jamal's next step?
Jamal should find the a(midpoint of each leg) b(midpoint of d) c(length of each leg)
by a(adding the x coordinate and y coordinate) b(squaring x coordinate and y coordinate) c(subtracting x coordinate and y coordinate)
.
Answer:
Jamal should find the Length of each leg by Subtracting the x coordinates and the y-coordinates and y-coordinates.
Step-by-step explanation:
Ansewer for Edmentum:)
Jamal's next step is : Jamal should find the length of each leg by subtracting x coordinate and y coordinate
What is right triangle?"It is a triangle whose one the angle measures 90°"
What is Pythagoras theorem?"In a right triangle [tex]c^{2} =a^{2} +b^{2}[/tex] where c is the hypotenuse and a, b are other two sides of right triangle."
What is the distance formula?"The distance between two points [tex](x_1,y_1),(x_2,y_2)[/tex] is given by [tex]s=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] "
For given question,
Jamal wants to find the length of 'd'
For right triangle in the figure, 'd' is the hypotenuse.
Jamal should find the other two sides of the triangle.
And then using Pythagoras theorem, Jamal can find the length of 'd'
So, Jamal need to find the length of each leg by subtracting x coordinate and y coordinate.
Therefore, Jamal's next step is : Jamal should find the length of each leg by subtracting x coordinate and y coordinate

Plz help this is for a grade‼️ the ratio of males to females in the middle school is 6:8. If there are 126 make students,how many female students are there?
Answer:
168 girls
Step-by-step explanation:
126 boys and 168 girls.
Answer:
The answer should be 168 female students.
Step-by-step explanation:
Since the ratio of males to females is 6:8 and there's 126 male students, by dividing 126 by 6 you can get 21 then using that 21 you can multiply it by 8 to find how many female students there are which is 168 and dividing 126:168 by 21 you can get 6:8.
126 divided by 21=6
168 divided by 21=8

A bird was sitting 8 meters from the base of an oak tree. It then flew in a straight line 9 meters to reach the top of the tree.
How tall is the tree?
The tree is
meters tall.
Note: Round your answer to the nearest hundredth.
Answer:
wouldn't it be 17 meters?
=========================================================
Explanation:
Draw a right triangle. The horizontal leg is 8 meters. The hypotenuse is 9 meters. The vertical height is unknown, so we'll call it x.
Apply the pythagorean theorem to solve for x
[tex]a^2 + b^2 = c^2\\\\8^2 + x^2 = 9^2\\\\64 + x^2 = 81\\\\x^2 = 81-64\\\\x^2 = 17\\\\x = \sqrt{17}\\\\x \approx 4.1231056\\\\x \approx 4.12\\\\[/tex]
The tree is approximately 4.12 meters tall
