The given function :
To find the value of f(-2)
Substitute x =-2 in the above function , we get
Hence, the value of f(-2)= -3
Triangle BDC is an isoceles triangle
Then triangle ADC
LCD stands for Lowest Common Denominator.
So let's say we have the equation 1/9 * 16/27
We want to find the LCD of both fractions. To find the LCD of both fractions find a the lowest common denominator in both fractions.
In this equation the lowest common denominator is 27 because 9 can go in 27 and 27 can go into itself. Se basically 27 is the lowest possibly common denominator both fractions can get to.
Hope This Helped! Good Luck ;)
Ocd means Obsessive compulsive disorder. I have OCD so this caught my eye. These are symptoms of ocd (Symmetry,Arranging, and counting). Just right Ocd is is the 'C' part of ocd. Compulsive. Symmetry,Arranging, and counting are compulsive.
(hope this helps)
To find the value of x we need atleast 2 other angles, and we do we have one 70, but we need to get another angle from the info given outside the triangle,
Notice, the angle beside 100 can be found by simply subtracting 180-100
(since angles are on a straight line [Supplementary angles]
So, the angle is 80
Now, we know that the angles inside a triangle add up to 180
So basically, to find x:
70+80+x = 180
150+x = 180
x = 180-150
Hoep this helps!
Mark brainliest if you think i helped! Would really appreciate!
ΔBDC is isosceles, meaning the two base angles are equal. to find them you need to:
180 - 30 = 150 ÷ 2 = 75. so , each of the base angles is 75°
∠BDC + ∠BCD = ∠ABD
30 + 75 = 105°
so, x = 180 - (105+65) = 10°
you will understand better if you draw the figure and fill in all the angles following my explanation.
x = 10°
First of all, when people say 'find the zeros' they basically mean 'find the solutions.' The reason for calling them 'zeroes' is ACTUALLY important. It tells you WHAT a solution is.
Many people, even people who are all the way up in pre-calculus don't know this...
The solutions of a function are the points at which it crosses the x-axis.
With that being said, let's find the zeros of this function:
First of all, we must factor it.
We can find the solutions by setting these equal to 0!
Now, those are your answers. Continue if you want to learn something interesting.
Look at the above picture of the graph. I want you to look at where the graph touches the x-axis. These are the solutions.
Now I will point out something interesting.
There are 3 ways in which a polynomial function touches the x-axis. I like to call them the...
Cross through: this is when the graph goes strait through the x-axis like a line.
Bounce: this is when the graph touches the x-axis at one point and then bounces back.
Wiggle through: this is when the graph makes a little 'wiggle' as it crosses the x-axis.
WHY am I pointing this out?
Well, the way in which the graph crosses the x-axis will tell you how many of the same factor the equation has.
Cross through: This indicates that the graph only has one factor that equals the value of the point it crosses through
Example: y=(x-2)(x-2)(x+1) this means at -1, the graph crosses strait through the x-axis.
Bounce: like in our example, a bounce indicates that there are two factors that equal the value of the point it touches.
Example: y=(x+2)(x-2)(x+2)(x-2) this means that at -2 and 2, the graph bounces off the x-axis
Wiggle: this indicates that 3 factors that equal the value of the point it crosses through
Example: y=(x+1)(x+1)(x+1)(x-2) the graph wiggles through the x-axis at -1
I hope this helps! Ty for reading:)
W = width
H = height
D = diagonal of the 3D rectangular solid
D = sqrt(L^2+W^2+H^2)
which is essentially a 3D extension of the 2D pythagorean theorem c = sqrt(a^2+b^2)
For example, if
L = 3, W = 4 and H = 10,
D = sqrt(L^2+W^2+H^2)
D = sqrt(3^2+4^2+10^2)
D = sqrt(9+16+100)
D = sqrt(125)
D = 11.1803 which is approximate
In this example, the length of the diagonal is roughly 11.1803 units long
This is the distance from one corner to the furthest opposite corner. The diagonal goes through the solid itself and does not simply stay on one face only.
