Step-by-step explanation:
The solution would be where the two graphs intersect or touch (where the line and the parabola intersect or touch).
Look at the two dots on the plane, where the line and parabola intersect--those are the answers.
If a triangle has side lengths 7, 10, and 12, is it a right triangle??
Answer:
No. Remember, a right angle must have a 90 degree angle. We can find the lengths with the Pythagorean Theorem.
Step-by-step explanation:
Given the length 7, 10, and 12, we can assume that 12 is the hypotenuse (it is the longest length).
- we can use 7 and 10 interchangeably.
Fill in the equation, [tex]a^2 + b^2 = c^2[/tex]
where c = 12, and a or b = 7 or 10.
To indicate if the given lengths would form a right angle, we can only input 7 or 10, not both.
Therefore, [tex]7^2 + b^2 = 12^2[/tex] or [tex]10^2 + b^2 = 12^2[/tex]
[tex]7^2 + b^2 = 12^2[/tex] ==> 49 + b^2 = 144 ==> b= [tex]\sqrt{95[/tex] ==> 9.746
b= 9.7, not 10.
[tex]10^2 + b^2 = 12^2[/tex] ==> 100 + b^2 = 144 ==> b = [tex]\sqrt{44[/tex] ==> 6.633
b= 6.6, not 7.
Therefore, the lengths 7, 10, and 12, does NOT make a right triangle.
Hope this helps!
A survey of Lakeview High School students found that 72% of the students had eaten breakfast that morning. If two students are chosen at random from a group of 100 students, what is the probability that at least one of them did not eat breakfast that morning?
Answer:
4.26 * 10^-12
Step-by-step explanation:
Usibg the binomial probability relation :
P(x =x) = nCx * p^x * q^(n-x)
Probability of success = probability of not eating = 1 - 0.72 = 0.28
p = 0.28
q = 1 - p = 0.72
Probability that atleast one out of 2 chosen did not eat breakfast :
P(x ≥ 1) = p(x = 1) + p(x = 2)
P(x ≥ 1) = (100C1 * 0.28^1 * 0.72^99) + (100C2 * 0.28^2 * 0.72^98)
= 4.26 * 10^-12

Is the triangle a right triangle?
4 6 7
Is this a right triangle?
Answer:
No
Step-by-step explanation:
Given :-
A triangle with some side measure .The sides are 4 ,6,7.And we need to tell whether it is a right angled triangle or not . It will be a right angled triangle if it follows the Pythagoras Theorem.
Pythagoras Theorem :-
In right angle triangle the sum of squares of the two smallest sides is equal to the square of the largest side .Here the two smallest sides are 4 & 6 .
Sum of Squares of 4 and 6 :-
[tex]:\implies[/tex] 4² + 6²
[tex]:\implies[/tex] 24 + 36
[tex]:\implies[/tex] 60
Square of 7 :-
[tex]:\implies[/tex] 7²
[tex]:\implies[/tex] 49
And :-
They aren't equal. So the triangle is not a right angled triangle .Hence the triangle is not a right angle triangle.
Answer:
No, this triangle is not a right triangle.
Step-by-step explanation:
Step 1: Definition(s)/explanations
This is a right triangle, so the Pythagorean Theorem applies.The Pythagorean Theorem states that the legs of the triangle, squared, must equal the hypotenuse, squared.The legs of the triangle are the sides that make the right angle.The hypotenuse is the longest side.Formula:
[tex]pt-a^2+b^2=c^2[/tex]
[tex]legs=a,b[/tex]
[tex]hypotenuse=c[/tex]
Step 2: Solve.
Now, I just plug the numbers into the formula.
[tex]a^2+b^2=c^2[/tex]
[tex]4^2+6^2=7^2[/tex]
[tex]16+36\neq 49[/tex]
If the legs of the triangle do not equal the hypotenuse, then the triangle cannot be a right triangle.
Step 3: Conclude.
Therefore, the triangle cannot be a right triangle.

Answer:
[tex]5(x + 10)(10x - 3)[/tex]
Step-by-step explanation:
We are factoring
[tex]50x^{2} + 485x - 150[/tex]
So:
((2•5^2x^2) + 485x) - 150
Pull like factors :
50x^2 + 485x - 150 = 5 • (10x^2 + 97x - 30)
Factor
10x^2 + 97x - 30
Step-1: Multiply the coefficient of the first term by the constant 10 • -30 = -300
Step-2: Find two factors of -300 whose sum equals the coefficient of the middle term, which is 97.
-300 + 1 = -299
-150 + 2 = -148
-100 + 3 = -97
-75 + 4 = -71
-60 + 5 = -55
-50 + 6 = -44
-30 + 10 = -20
-25 + 12 = -13
-20 + 15 = -5
-15 + 20 = 5
-12 + 25 = 13
-10 + 30 = 20
-6 + 50 = 44
-5 + 60 = 55
-4 + 75 = 71
-3 + 100 = 97
Step-3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -3 and 100
10x^2 - 3x + 100x - 30
Step-4: Add up the first 2 terms, pulling out like factors:
x • (10x-3)
Add up the last 2 terms, pulling out common factors:
10 • (10x-3)
Step-5: Add up the four terms of step 4:
(x+10) • (10x-3)
Which is the desired factorization
Thus your answer is
[tex]5(x + 10)(10x - 3)[/tex]
Answer:
[tex] \displaystyle \rm 5({x}^{} + 10)( 10x - 3)[/tex]
Step-by-step explanation:
we would like to factor out the following expression:
[tex] \displaystyle {50x}^{2} + 485x - 150[/tex]
notice that, in every term there's a common factor of 5 thus factor it out:
[tex] \displaystyle 5( {10x}^{2} + 97x - 30)[/tex]
now we have to rewrite the middle term as sum or substraction of two different terms in that case 100x-3x can be considered:
[tex] \displaystyle 5( {10x}^{2} + 100 - 3x - 30)[/tex]
factor out 10x:
[tex] \displaystyle 5( 10({x}^{2} + 10)- 3x - 30)[/tex]
factor out -3:
[tex] \displaystyle \rm 5( 10x({x}^{} + 10)- 3(x + 10))[/tex]
group:
[tex] \displaystyle \rm 5({x}^{} + 10)( 10x - 3)[/tex]
and we are done!
hence,
our answer is B)

What are m<1 and m<2? Please help me
Answer:
Your answer is B
Step-by-step explanation:
The rule for angles is that 115 and the angles right next to it, the ones that form the x, will equal 180. That means all you have to do is 115-180=65.
Another rule is that the interior angles of a triangle will be 180, so you add the angles we know in each triangle, 80+65+angle 1 = 180. If you do this correctly you should get angle 1 to be 35. Then you repeat on the opposite side except this time the angles are 85+65+angle 2 = 180. If you do this one correct you should get 30. Which makes your answer B.

Explain how changes in the dimensions of a cube dimensions affect the volume of a cube. Be specific, explaining how much the volume will change with each increase of 1 unit on the side lengths. Please give a clear explanation!
Answer:
When the dimensions of the shape, such as radius, height, or length change, both surface area and volume also change. However, the volume of the object always changes more than the surface area for the same change in dimensions.

Answer:
The surface area of the parallelogram is;
2x^3 -6x^2 - 14x +24 squared centimeters
Step-by-step explanation:
To get the area of the parallelogram, we need to multiply the base length of the parallelogram by the height of the parallelogram
We have this as follows;
(x-4)(2x^2+2x-6)
= x(2x^2 + 2x-6) -4(2x^2 + 2x-6)
= 2x^3 + 2x^2 - 6x -8x^2 -8x + 24
= 2x^3 +2x^2 -8x^2 -6x-8x+24
= 2x^3 -6x^2 - 14x +24
How do I graph these points on a graph?
(-1/2, -3/2)
Answer:
Start at origin (0,0)
Move 1/2 units left
Move 1 and 1/2 units down
Place your point
Step-by-step explanation:
Start at the origin (0,0)
Move 1/2 units to the left
Then move 1 1/2 units down, and place your point.
The first coordinate is locating the position horizontally, or on the x axis
The second coordinate is locating the position vertically, or on the y axis.
If there is a negative number on the x coordinate, the first one, you move left.
If positive, you move right.
If there is a negative number on the y coordinate, the second one, you move down.
If positive, you move up.

WILL GIVE 100 POINTS TO WHOEVER ANSWER THIS CORRECTLY. In the similarity transformation of abc to def, abc was dilated by a scale factor of ?, reflected across the , and moved through the translation
Answer:
Dialated by a scale factor of two, reflected across the x axis, and transformed three units left
Step-by-step explanation:
The triangle was dilated by a scale factor of 2
What is similarity transformation?
One or more stiff transformations (such as reflection, rotation, and translation) followed by a dilation make up a similarity transformation. An image that resembles the original figure is produced when a figure undergoes a similarity transformation.
The following steps are followed while determining the similarities:
Step 1 is to identify the triangles' pairs of corresponding sides and pairs of matching angles. Step 2 Redraft the triangles with the same orientation and space between them. Step 3 Give the triangles names and create a similarity assertion,making sure to maintain the order of corresponding vertices.Solution:
Given:
AB=2, AC=1, BC=√5
DC=4, DF=2, EF=2√5
So scale factor is 4/2 = 2/1 = 2√5/√5 = 2
hence we get tha scale factor as 2.
Therefore, In the similarity transformation of abc to def, abc was dilated by a scale of 2.

can u explain how to do this
Answer:
x=41
Step-by-step explanation:
so since this is a right triangle you can use the Pythagorean Theorem to find the missing side. the two sides you know are 'a' and 'b' and the missing side is 'c'. the theorem says that:
a^2+b^2=c^2
so:
9^2 +40^2=c^2
solve for the exponents:
81 +1600=c^2
1681=c^2
and now, since 1681 is the missing side's length squared, we must find the square root of 1681, which is 41
