Answer:
The equation of the perpendicular bisector line
5 x - 2 y + 31 =0
Step-by-step explanation:
Explanation:-
Given points are ( 0,1) and (-10,5)
The Midpoint of given two points
[tex](\frac{x_{1}+x_{2} }{2} , \frac{y_{1}+y_{2} }{2} )[/tex]
(-5 , 3)
The Slope of the line
m = [tex]\frac{y_{2} -y_{1} }{x_{2}-x_{1} } = \frac{5-1}{-10} = \frac{-2}{5}[/tex]
The perpendicular slope
= [tex]\frac{-1}{m} = \frac{-1}{\frac{-2}{5} } = \frac{5}{2}[/tex]
The equation of the perpendicular bisector line
[tex]y - y_{1} = m (x - x_{1} )[/tex]
[tex]y - 3 = \frac{5}{2} ( x-(-5))[/tex]
2 y - 6 = 5( x +5)
5 x + 25 -2y +6 =0
5 x - 2 y + 31 =0

If Log 20 = 1.301 what is the value of Logsub100 20?
I need the step by steps! I can’t find anything videos online to teach this to me
Answer:
[tex]log_{100}20 = 0.6505[/tex]
Step-by-step explanation:
log20 = 1.301 (when you see only "log" with no base, it is taken as a base 10)
This basically means:
[tex]10^{1.301} = 20[/tex] (This is the log in exponential form)
Since we don't know what [tex]log_{100}20[/tex] is equal to, we will say [tex]log_{100}20[/tex] = x
So to solve for [tex]log_{100}20[/tex] = x, you do the same thing. (convert to exponential form)
[tex]100^{x} =20[/tex]
Now you will notice that both of these equations are equal to 20.
Since 20 = 20,
we can say [tex]100^{x}[/tex] = [tex]10^{1.301}[/tex]
Another way of saying 100, is [tex]10^{2}[/tex] (make the bases the same)
Now we get [tex]10^{2x} = 10^{1.301}[/tex]
(we get 2x because an exponent to the power of an exponent ([tex]2^{x}[/tex]) is the same as 2 * x)
Because you have the same base, you can just ignore the 10s and focus on the exponents. So you get:
2x = 1.301
x = 0.6505

What is the distance between the points (-9,5) and (8,5)
Answer:
17 units
Step-by-step explanation:
Use distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex], to find the distance between (-9, 5) and (8, 5):
Let,
[tex] (x_1, y_1) = (-9, 5) [/tex]
[tex] (x_2, y_2) = (8, 5) [/tex]
Plug in the values into the distance formula:
[tex] d = \sqrt{(8 - (-9))^2 + (5 - 5)^2} [/tex]
[tex] d = \sqrt{(17)^2 + (0)^2} [/tex]
[tex] d = \sqrt{(289 + 0)} [/tex]
[tex] d = \sqrt{289} [/tex]
[tex] d = 17 [/tex]

If 2^3x-1 = 32 then x = (image included)
a. 5
b. -2
c. 2
d. 4/3
e. -4
Answer:
x is equal to two.
Step-by-step explanation:
We know that 32 is a power of 2. It is in fact two to the power of five. So we can re-express that as:
[tex]2^{3x - 1} = 2^5[/tex]
Because they have the same constant as a base, we can toss the base altogether, and equate the exponents:
[tex]3x - 1 = 5\\3x = 6\\x = 2[/tex]

Step-by-step explanation:
We know that opposite sides of parallelogram are equal so
t + 10 = 3t
3t-t = 10
2t = 10
t = 10/ 2
t = 5
Therefore the value of the should be 5 so that it makes a parallelogram.

Question
If f(x) = x^2 + 7x and g(x) = 3x - 1, what is f(g(x))?
O 9x2 + x + 1
9x2 + 15x - 6
9x2 + 21x-6
9x2 - 27x
Help please
Answer:
9x^2 + 15x -6
Step-by-step explanation:
Your problem → If f(x) = x^2 + 7x and g(x) = 3x - 1, find f(g(x))?
f(x)=x2+7x,g(x)=3x-1,fog(x)=?
g(x)=3x-1,f(x)=x2+7x
fog(x)=f(g(x))
=f(3x-1)
=(3x-1)2+7⋅(3x-1)
=(3x-1)2+21x-7
=(9x2-6x+1)+21x-7
=9x2+15x-6
fog(x)=9x2+15x-6
SUP= 125 UPE=110 SRE=85 find SUR
Answer:
m∠SUR = 15°
Step-by-step explanation:
m∠UPE = 110°
m∠UPR = m∠EPR [Given]
m∠UPR = [tex]\frac{1}{2}(m\angle UPE)[/tex]
= [tex]\frac{1}{2}(110)[/tex]
= 55°
Since, m∠SRU = m∠UPR [Given in the picture]
m∠SRU = 55°
m∠SRE = m∠SRU + m∠URP + m∠PRE
85° = 55° + m∠URP + m∠PRE
m∠URP + m∠PRE = 30°
Since, m∠URP = m∠PRE
m∠URP + m∠URP = 30°
m∠URP = 15°
Since, m∠URP = m∠SUR [Given in he picture]
m∠SUR = 15°

15-a=20 what value would make this true
Answer:
a = -5
Step-by-step explanation:
15 - a = 20
Move the constant of 15 to the other side by subtracting it.
-a = 5
Divide by -1 to make a positive.
a = -5
Check.
15 - (-5) = 20
15 + 5 = 20
20 = 20
Answer:
-5
Step-by-step explanation:
15-(-5)=20
5 turns into a positive

Which graph is the graph of y-2=4(x+5)
Answer:
The answer is C
Answer:
A
Step-by-step explanation:
y=4(x+5)+2
y=4x+20+2
y=4x+22
The Y-intercept is going to be 22, so we can already eliminate D and C. and so the difference between A and B is that B is a negative line and A is not. And since the slope is not negative in the equation, B cannot be the answer, so A is the answer.
Which is an x-intercept of the graph of the function Y = Cot(3x)?
Answer:
A on ed 2021
Step-by-step explanation:
if you go on Desmos graphing calculator and graph y = cot(3x)
then graph the points
A. (pi/6, 0)
B. (pi/3, 0)
C. (3pi, 0)
D. (6pi, 0)
POINT A. (pi/6, 0) is the only point that intercepts the graph
The x-intercept of the graph of the function y = cot(3x) is ,
⇒ (π/6, 0)
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Here, The graph of the function is given as:
y = cot(3x)
Now, To determine the x-intercept of the graph, we set the graph to 0.
So, we have:
cot(3x) = 0
Take the arccot of both sides;
3x = arccot(0)
Evaluate the arccot of 0
3x = π/2
Divide both sides by 3
x = π/6
Hence, the x-intercept of the graph of the function y = cot(3x) is
⇒ (π/6, 0)

Find the missing side or angle.
Round to the nearest tenth.
B=18°
C=152°
b=4
c=[ ? ]
Answer:
c = 6.1
Step-by-step explanation:
Given that: B = 18° , C = 152°, and b = 4.
The missing side, c, can be determined by applying the sine rule which states that:
[tex]\frac{b}{Sin B}[/tex] = [tex]\frac{c}{Sin C}[/tex]
[tex]\frac{4}{Sin 18^{o} }[/tex] = [tex]\frac{c}{Sin 152^{o} }[/tex]
c = [tex]\frac{4* Sin 152^{o} }{Sin 18^{o} }[/tex]
= [tex]\frac{1.8779}{0.3090}[/tex]
= 6.0773
c = 6.1
Therefore, the value of the missing side, c, is 6.1
