Find the equation of the line that

and contains the point (8, 1).
y =
x+
Enter
Answers
Answer:
Step-by-step explanation:
L : y = -4x + 3
with a slope of -4.
Any line perpendicular to L will have a slope m such that
m ( -4) = -1, or m = 1/4
Any line perpendicular to L passing through point (a,b) will therefore have the form
P : (y-b) = (x-a)/4
When (a,b) = (8,1) as given, then substitute in P to get
P : (y-1) = (x-8)/4
y=x/4 -2 + 1
y = x/4 -1

`find the equatifindon of tangent and normal of parabola y²=16ax at point whose coordinate is -5a.
Answers
Answer:
[tex] \rm \displaystyle y _{ \rm tangent} = - \frac{8}{5} x - \frac{5}{2} a[/tex]
[tex] \rm \displaystyle y _{ \rm normal} = \frac{5}{8} x - \frac{765}{128} a[/tex]
Step-by-step explanation:
we are given a equation of parabola and we want to find the equation of tangent and normal lines of the Parabola
finding the tangent line
equation of a line given by:
[tex] \displaystyle y = mx + b[/tex]
where:
m is the slopeb is the y-interceptto find m take derivative In both sides of the equation of parabola
[tex] \displaystyle \frac{d}{dx} {y}^{2} = \frac{d}{dx} 16ax [/tex]
[tex] \displaystyle 2y\frac{dy}{dx}= 16a[/tex]
divide both sides by 2y:
[tex] \displaystyle \frac{dy}{dx}= \frac{16a}{2y}[/tex]
substitute the given value of y:
[tex] \displaystyle \frac{dy}{dx}= \frac{16a}{2( - 5a)}[/tex]
simplify:
[tex] \displaystyle \frac{dy}{dx}= - \frac{8}{5}[/tex]
therefore
[tex] \displaystyle m_{ \rm tangent} = - \frac{8}{5}[/tex]
now we need to figure out the x coordinate to do so we can use the Parabola equation
[tex] \displaystyle ( - 5a {)}^{2} = 16ax [/tex]
simplify:
[tex] \displaystyle x = \frac{25}{16} a[/tex]
we'll use point-slope form of linear equation to get the equation and to get so substitute what we got
[tex] \rm \displaystyle y - ( - 5a)= - \frac{8}{5} (x - \frac{25}{16} a)[/tex]
simplify which yields:
[tex] \rm \displaystyle y = - \frac{8}{5} x - \frac{5}{2} a[/tex]
finding the equation of the normal line
normal line has negative reciprocal slope of tangent line therefore
[tex] \displaystyle m_{ \rm normal} = \frac{5}{8}[/tex]
once again we'll use point-slope form of linear equation to get the equation and to get so substitute what we got
[tex] \rm \displaystyle y - ( - 5a)= \frac{5}{8} (x - \frac{25}{16} a)[/tex]
simplify which yields:
[tex] \rm \displaystyle y = \frac{5}{8} x - \frac{765}{128} a[/tex]

On a coordinate plane, line A B goes through (negative 2, 4) and (2, negative 8). Point C is at (6, 4).
Which point on the y-axis lies on the line that passes through point C and is perpendicular to line AB?
(–6, 0)
(0, –6)
(0, 2)
Answers
Answer:
A. (-6,0)
Step-by-step explanation:
The point on the y-axis lies on the line that passes through point C and is perpendicular to line AB is (-6, 0). Therefore, option C is the correct answer.
Given that, on a coordinate plane, line AB goes through (-2, 4) and (2, -8). Point C is at (6, 4).
What is the slope of a line?The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of that line.
The slope is represented by the letter m, and is given by, m = tan θ = (y2 - y1)/(x2 - x1)
Now, slope of line AB with (x1, y1) = (-2, 4) and (x2, y2) = (2, -8) is
Slope = m = (-8-4)/(2(-2)
= -12/4
= -3
Slope perpendicular to AB = -1/m = -1/(-3)
=1/3
Put m=1/3 and C(6, 4) in y=mx+c, we get
4 = 1/3 (6) + c
⇒ c = 4-2
⇒ c = 2
Substitute m=1/3 and c = 2 in y = mx+c
That is, y = x/3 + 2
⇒ 3y = x+6
Point on the y-axis lies is 3(0) = x+6
⇒ x=-6
So, the coordinate is (-6, 0)
The point on the y-axis lies on the line that passes through point C and is perpendicular to line AB is (-6, 0). Therefore, option C is the correct answer.

Find area of shape?
Answers
Answer:
521.1 mm²
Step-by-step explanation:
The shape is made up of a semicircle and a trapezoid.
Area of the shape = area of the semicircle + area of the trapezoid
= ½(πr²) + ½(a + b)*h
Where,
r = radius of the semicircle = ½(20) = 10 mm
a = 20 mm
b = 32 mm
h = height of trapezoid = 14 mm
Plug in the values
Area of the shape = ½(π*10²) + ½(20 + 32)*14
= 157.1 + 364
= 521.1 mm²

Answers
Answer:
y=-1/2x+7
Step-by-step explanation:
I think its that
Answer:
y = (1/2) x + 3
Step-by-step explanation:
The equation of linear functions is y = m x + b
In this case, we know m = 1/2 , and have point (4,5). We only need to find our y-intercept or b value.
What we can do is substitute what we know into our formula which will give us variable b, or the y-intercept. That will look like:
5 = (1/2) * 4 + b
5 = 2 + b
3 = b
So, the equation is y = (1/2) x + 3 :)

I would greatly appreciate it if someone could help me with this. A car travelled 400 km in 5 hours. Joe calculated the speed as 80 km/h but, when he graphed the relation, he calculated a slope of 0.0125. What do you think Joe did incorrectly?
Answers
It sounds like Joe calculated 5/400 = 0.0125
He divided in the wrong order. It should be 400/5 = 80 since we divide distance over time to get the speed (or rate).
-----------------
In terms of x and y, we basically are saying
slope = rise/run
slope = (change in y)/(change in x)
slope = (change in distance)/(change in time)
slope = (400 km)/(5 hrs)
slope = 80 km per hour is the speed

C. 9 and 24
D. 9 and 25
No links or fake answers pls. Thank you for understanding.
Answers
Answer:
B) 8 and 24.
Step-by-step explanation:
Just by looking at the answer choices, since one number must be three times the other, we can determine that the correct answer is B.
Regardless, let's work this out mathematically. Let the first number be a and the second number be b.
Their difference is 16. Hence:
[tex]a-b=16[/tex]
The first number is three times the second number. So:
[tex]a=3b[/tex]
Substitute:
[tex]3b-b=16[/tex]
Solve for b. Subtract:
[tex]2b=16[/tex]
And divide both sides by two:
[tex]b=8[/tex]
So, the second number is 8.
And since the first number is three times the second, the first number is 24.
Our answer is B as expected.

this problem statement tries to confuse us. there is no pi involved - also because there are no round surfaces and edges involved.
what do you think the surface area of such a 4-sided pyramid consists of ?
think !
there are the 4 walls or sides. and then there is the bottom too (if you lift the pyramid up, yes, the "floor" or bottom also belongs to the surface area).
each "wall" or side is actually a triangle.
and the bottom is a square.
what is the area of a triangle (At) ?
At = base length × height / 2 = 3×11/2 = 33/2 in²
what is the area of a square (As) ?
it is a special form of a rectangle, where length = width.
the area of a rectangle (Ar) = length × width.
and the area of a square (As), where length = width is
As = side length × side length = length² = 3² = 9 in²
our pyramid now has 4 "walls", all of the same size, so we need 4 times the area of such a single triangle.
and then add the bottom area.
=> the pyramid surface area (Ap) is
Ap = 4 × At + As = 4×33/2 + 9 = 132/2 + 9 = 66+9 = 75 in²

Step-by-step explanation:
the 2 angles create a right angle ( indicated by the little square.)
right angles have a measure of 90 degrees
hence, 90 = 72 + 2x
( note that we just created an equation that we can use to solve for x )
we now solve for x using the equation we created.
90 = 72 + 2x
step 1 subtract 72 from each side
90 - 72 = 18
72 - 72 cancels out
we now have 18 = 2x
step 2 divide each side by 2
18 / 2 = 9
2x / 2 = x
we're left with x = 9
