Answer:
C,110°
Step-by-step explanation:
when the angle on circumference=50°
then the angle at center=2×50=100°
other angles of this triangle are equal and each=1/2(180-100)=1/2×80=40
so angle of quadrilateral=30+40=70°
as opposite angles of a cyclic quadrilateral are supplementary.
so y+70=180
y=180-70=110°

Find (F/g)(x)
F(x) = sqrt x^2-1
g(x) sqrt x-1
Answers
Answer:
Option A. √(x + 1)
Step-by-step explanation:
Data obtained from the question include:
f(x) = √(x² – 1)
g(x) = √(x – 1)
(f/g) (x) =..?
(x² – 1) => difference of two square
(x² – 1) => (x – 1)(x + 1)
f(x) = √(x² – 1)
f(x) = √(x – 1)(x + 1)
(f/g) (x) = f(x) /g(x)
f(x) = √(x – 1)(x + 1)
g(x) = √(x – 1)
(f/g) (x) = √(x – 1)(x + 1) / √(x – 1)
(f/g) (x) = √[(x – 1)(x + 1) / (x – 1)]
(f/g) (x) = √(x + 1)

Tom wants to save $846, he already has $23, and he deposits $87 each month, M.
Answers
Answer:
The answer is C.
Answer:
B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M.
Step-by-step explanation:
$846 = $87 + $23M
The $846 represents the amount that he wants to save. $23M represents how much money he wants to deposit every M months. $87 represents the amount that he has already deposited (the constant).
And so, the correct answer will be B. Tom wants to save $846, he already has $87, and he deposits $23 each month, M.

Answers
Answer:
x= 3/2 = 1.5
Step-by-step explanation:
● 5(4x-10)+10x =4(2x-3)+2(x-4)
Simplify the products
● 5*4x-5*10+10x = 4*2x-4*3+2*x-2*4
● 20x-50+10x = 8x-12+2x-8
Add the terms that don't contain x with each other
●20x-50+10x = 8x-20+2x
Add 20 in both sides
●20x-50+20+10x = 8x-20+2x+20
●20x-30+10x = 8x+2x
Add together the terms that contain x
●30x -30 = 10x
Add -10x in both sides
●30x-30-10x = 10x-10x
● 20x -30 = 0
Add 30 in both sides
● 20x-30+30 = 30
● 20x = 30
Divide both sides by 20
●20x/20 = 30/20
● x= 30/20
● x= 3/2
● x= 1.5

if (ax+b)(ax+c)=4x^2-25 for all values of x, and a, b, and c are constants, what is the value of b+c?
Answers
Answer: 10.
Step-by-step explanation:
You are given the equation
(ax+b)(ax+c)=4x^2-25
Expand the Left hand side by opening the bracket.
a^2x^2 + axc + abx + bc
a^2x^2 + (axc + abx) + bc = 4x^2 + 0x - 25
From the equation above, we can see that;
a^2x^2 = 4x^2
a^2 = 4
a = √4
a = 2
Also, axc + abx = 0x
axc = abx
ax will cancel out from both sides
c = b
From the equation, bc = 25
But c = b. Substitute c for b
b^2 = 25
b = √25
b = 5 = c
b + c is therefore 5 + 5 = 10

Good luck on your assignment..
Explanation:
3/4(2-3x)=0
(6-9x)/4=0
6-9x=0 x 4
6-9x= 0 (any number time 0 is 0)
-9x=-6
x=-6/-9
x=2/3
Now let’s use x in our equation
3/4(2-3x)=0
now plug x=2/3
3/4(2-3 x 2/3)=0
3/4(2-6/3)=0
3/4(2-2)=0
3/4(0)=0
0=0 (any number time 0 is 0)
And so x = 2/3 is the right answer

Find the indicated measure.
Answers
Answer:
Arc EFC has a measure of 234 degrees.
Step-by-step explanation:
The measure of arc EFC = the measure of arc EF + the measure of arc BF + the measure of arc BC.
Arc BFE looks like a semicircle.
A semicircle has a measure of 180 degrees.
Arc BF + arc FE = 180 degrees
Arc BF has a measure of 126 degrees.
126 + arc FE = 180
arc FE = 54 degrees
Arc FE = Arc BC
Their central angles are equal by vertical angle theorem.
EFC = EF+BF+BC
EFC = 54 + 126 + 54

Find the value of the expression below.
log5 2 + log5 10 - log5 4
Answers
Answer:
A. 1
Step-by-step explanation:
To find the value of the expression, we will follow the steps below:
log₅2 + log₅10 -log₅4
From the rules of logarithm
logₐb + logₐc = logₐbc
similarly
logₐb - logₐc = logₐb/c
applying the two rules above to our expression will yield:
log₅2 + log₅10 -log₅4
=log₅(2 x 10) /4
=log₅20/4
=log₅5
also according to the rule of logarithm, logₐa=1
Therefore,
log₅5 =1
Therefore, the correct answer is 1

In general for a rectangle of dimensions w by h and a semicircle of diameter w we get an area:
A = wh + \frac 1 2 \pi (\frac w 2)^2
The halfs are because a semicircle is half a circle and a radius is half a diameter.
We're told
h = 1+ 3w
Substituting,
A(w) = w(1+3w) + \frac 1 2 \pi (\frac w 2)^2
