Answer:
Area=128
Step-by-step explanation:
p=8[tex]\sqrt{2}[/tex]
A=p^2
put value of p
A= (8[tex]\sqrt{2}[/tex])power2
A= (8^2* [tex]\sqrt{2}[/tex]^2)

The parent equation would be y=x^2 because that is the parent equation of a quadratic function. ;)
Ive been stuck with this for a while now please help
To write 2^7, you would do 2*2*2*2*2*2*2 because your multiplying 2 by itself 7 times. The only factor is, 2. Now try and do the rest, if you still need help, comment and I'll edit my answer and give you more hints. you got this. I believe in you :)

WILL GIVE BRAINLIEST! Determine the coordinates of the point on the straight line y=3x+1 that is equidistant from the origin and (−3, 4).
Answer:
[tex](\frac{17}{18}, \frac{23}{6})[/tex]
Step-by-step explanation:
D1 = [tex]\sqrt{(x+3)^2 + (y-4)^2}[/tex]
D2 = [tex]\sqrt{x^2 + y^2}[/tex]
Then set D1 = D2, and substitute in y = 3x+1
[tex]\sqrt{(x+3)^2 + (3x-3)^2}[/tex] = [tex]\sqrt{x^2 + (3x+1)^2}[/tex]
[tex]x^2 +6x +9 +9x^2 - 18x + 9 = x^2 + 9x^2 + 6x + 1[/tex]
[tex]18x = 17[/tex]
x = 17/18
Then to find y, substitute back in x for y = 3x + 1
[tex]y = \frac{17}{18} * 3 + 1[/tex]
y = 23/6
The coordinates of the point on the straight line y = 3x + 1 is [tex](\frac{17}{18} ,\frac{23}{6} )[/tex].
Here,
The equation of straight line is y = 3x + 1
And, it is equidistant from the origin and (-3, 4)
We have to find the coordinates of the point on the straight line.
What is the distance between the two points?
The length of the line segment that connects the two given points, is called distance between two points.
Now,
Let the point (x, y) on the line y = 3x + 1.
Distance between the points (x, y) and (0, 0) is;
[tex]D = \sqrt{(x-0)^2+(y-0)^2}[/tex]
[tex]D = \sqrt{x^{2} +y^{2} }[/tex]
And, Distance between the points (x, y) and (-3, 4) is;
[tex]D = \sqrt{(x+3)^2+(y-4)^2}[/tex]
[tex]D = \sqrt{x^{2} +6x+9+9x^{2} -18x+9}[/tex]
Equating both distance we get;
[tex]\sqrt{x^{2} +6x+9+9x^{2} -18x+9} = \sqrt{x^{2} +y^{2} }\\\\ {x^{2} +6x+9+9x^{2} -18x+9} = x^{2} + y^{2} \\\\18x = 17\\\\x = \frac{17}{18}[/tex]
And, To find y put the value of x in y = 3x + 1, we get;
[tex]y = 3 * \frac{17}{18} + 1\\\\y = \frac{23}{6}[/tex]
Hence, The coordinates of the point on the straight line y = 3x + 1 is [tex](\frac{17}{18} ,\frac{23}{6} )[/tex].

Write the equation g(x) of the transformation of the parent graph f(x) = |x| stretched vertically by a factor of 4 and translated up 2 units.
Answer:
g(x) = 4|x| +2
Step-by-step explanation:
f(x) = |x|
y = f(x) + C C > 0 moves it up
g(x) = |x| +2 moves it up 2 units
y = Cf(x) C > 1 stretches it in the y-direction
g(x) = 4|x| +2 stretch by 4
We start off with: f(x) = |x|
c > 0 means move up
y = f(x) + c
2 units up
After: g(x) = |x| + 2
c > 1 means y-direction stretch
y = cf(x)
4 unit stretch
After: g(x) = 4|x| + 2

does the point 2,4 lie on the line y=5x-6?
Answer:
substitute value of x and y as 2 and 4
y=5x-6
4= 5*2-6
4=4 so yes
Step-by-step explanation:
The point (2, 4) lie on the line y = 5x-6
What is an equation?An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.
For example, 3x + 5 = 15.
Given that, we need to check whether the point 2,4 lie on the line y=5x-6 or not,
So, the verification of the same, we will simply put the value of x (2) in the equation and see whether we are getting 4 or not, if not then points do not lie on the line, if yes, the point lies on the line.
So, the equation is
y = 5x-6
Put x = 2,
y = 5(2) - 6
y = 10-6
y = 4
Since, we get the value of y = 4, therefore, the point lies on the line.
Hence, the point (2, 4) lie on the line y = 5x-6

Torque is described as T = r * F, where r = radius which is measured in feet from the fulcrum point and F = Force which is measured in pounds. What is a possible unit measure for Torque?
Answer:
(pound-feet)
Step-by-step explanation:
Given that:
Torque = r × F
Where ; r = radius in feet ; F = force in pounds
Hence, a possible unit measure of torque using the units provided for both force and Radius will be :
r (feet) × F (pounds) = Torque (pound-feet)
Hence, the possible unit of measure of torque = (pound-feet)
Other unit measure may be :
r (metres) × F(Newton) = Torque (newton-metre)

The measure of the supplement of an angle exceeds 3 times the measure of the complement of the angle by 10. Find the measure of the complement.
Step-by-step explanation:
Let the angle be x.Let the supplement of the angle = 180 - xLet the complement of the angle = 90 - xNow, According to our assumption we can set up an equation :
➵ (180 - x) - 3(90 - x) = 10
➵ 180 - x - 270 + 3x = 10
➵ 2x - 270 = 10 - 180
➵ 2x - 270 = -170
➵ 2x = -170 + 270
➵ 2x = 100
➵ x = 100/2
➵ x = 50
Therefore,The angle = x = 50°The supplement of the angle = 180-x = 180 - 50 = 130°The complement of the angle = 90 - x = 90 - 50 = 40°what is the quotient of a number and 5

are all composite numbers even
Answer:
No.
Step-by-step explanation:
A composite number has factors in addition to one and itself. The numbers 0 and 1 are neither prime nor composite. All even numbers are divisible by two and so all even numbers greater than two are composite numbers. All numbers that end in five are divisible by five. Therefore all numbers that end with five and are greater than five are composite numbers.
∠A and \angle B∠B are complementary angles. If m\angle A=(x-21)^{\circ}∠A=(x−21) ∘ and m\angle B=(2x-15)^{\circ}∠B=(2x−15) ∘ , then find the measure of \angle A∠A.
Answer:
A = 21 degrees
Step-by-step explanation:
Here in this question, we are told to calculate the value of angle A.
When two angles are tagged complementary, what this means is that the addition of both angles gives a total of 90 degrees.
Hence;
A + B = 90
This means that;
(x-21) + (2x -15) = 90
x + 2x -21-15 = 90
3x -36 = 90
3x = 90+ 36
3x = 126
x = 126/3
x = 42
But we are told to calculate the measure of A
A = x -21
A = 42-21
A = 21 degrees

21
