Please help. First correct answer gets brainliest.
Answer:
63.5°
Step-by-step explanation:
By inscribed angle theorem:
[tex] m\angle XYZ=\frac{1}{2} \times m\widehat {XZ} [/tex]
[tex] \therefore m\angle XYZ=\frac{1}{2} \times 127\degree [/tex]
[tex] \therefore m\angle XYZ=63.5\degree [/tex]

Step-by-step explanation:
Solve the inequality and represent your solution on the number line below.
-3x + 14< 5
Answer: X > 3
Step-by-step explanation:
You want to subtract 14 on both sides and you will get -3x < -9. Then you divide -3 on both sides -3x/3 > -9/-3 and you should end up with x < 3. Since you divided by the negative number you switch the sign from ">" to "<"

The function f(x) is multiplied by a factor of 2 and then 3 is added to the function.
f(x) = sin(x)
What effect does this have on the graph of the function?
A.) The graph is vertically compressed by a factor of 3 and shifted up 2 units.
B.) The graph is vertically stretched by a factor of 3 and shifted up 2 units.
C.) The graph is vertically compressed by a factor of 2 and shifted up 3 units.
D.) The graph is vertically stretched by a factor of 2 and shifted up 3 units.
Given:
The function is:
[tex]f(x)=\sin x[/tex]
The function f(x) is multiplied by a factor of 2 and then 3 is added to the function.
To find:
The effect on the graph of the function.
Solution:
The transformation is defined as
[tex]g(x)=kf(x)+b[/tex] .... (i)
Where, k is stretch factor and b is vertical shift.
If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
It is given that the function f(x) is multiplied by a factor of 2 and then 3 is added to the function. So, the new function is:
[tex]g(x)=2f(x)+3[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]k=2[/tex], it means the graph is vertically stretched by a factor of 2.
[tex]b=3[/tex], it means the graph is shifted up 3 units.
Therefore, the correct option is D.
Answer:
D.) The graph is vertically stretched by a factor of 2 and shifted up 3 units

Answer:
C. 6x² +20x +30
Step-by-step explanation:
The perimeter of a rectangle is given by the formula ...
P = 2(L +W)
Substituting the given length and width, you have ...
P = 2((3x² +7x +9) +(3x +6))
Simplifying gives ...
P = 2(3x² +10x +15)
P = 6x² +20x +30

"Standard form" has the terms in order of decreasing exponents. The expression of choice D is equivalent, but is not in standard form.

Which could be the dimensions of a rectangular prism whose surface area is greater than 140 square feet? Select three options.
Answer:
6 feet by 5 feet by 4 feet
7 feet by 6 feet by 4 feet
Step-by-step explanation:
The surface are of rectangular prism = 140 ft²
Surface area of rectangular prism is given by :
A = 2(lw + lh + wh)
Using trial by error method :
6 feet by 2 feet by 3 feet
A = 2(6*2 + 6*3 + 2*3) = 72ft²
6 feet by 5 feet by 4 feet
A = 2(6*5 + 6*4 + 5*4) = 148 ft²
7 feet by 6 feet by 4 feet
A = 2(7*6 + 7*4 + 6*4) = 188ft²
8 feet by 4 feet by 3 feet
A = 2(8*4 + 8*3 + 4*3) = 136ft²

‘I-Moons’ charges $12 per album downloaded and an initial joining fee of $3. ‘I-Toons’ Charges $10 per album downloaded and a joining fee of $9. Write a system of linear equations that models this situation. Determine how many albums (x) it will take for the cost (y) to be the same. What does that cost?
Answer:
y = 3 + 12x - - - (1)
y = 9 + 10x - - - (2)
3 albums
$39
Step-by-step explanation:
Let number of download = x
Given :
I-moon :
Initial joining fee = $3
Cost per download = $12
Hence,
y = 3 + 12x - - - (1)
I - Toons :
Initial joining fee = $9
Cost per download = $10
y = 9 + 10x - - - (2)
For cost to be the same ;
Equate (1) and (2)
3 + 12x = 9 + 10x
Collect like terms
3 - 9 = 10x - 12x
-6 = - 2x
x = 3
It will take 3 albums
Cost :
3 + 12(3)
3 + 36 = 39

Interest: $
Total she owed: $
Answer:
Use Simple Interest Formula=PrT/100
SI=$1800×5×6/12÷100
=4500/100
=$45
Step-by-step explanation:
$45 is the interest that's gonna be owed after 6months so therefore the total $ she owed after 6 months would be: $45 + $1,800=$1,845.
Escriba larazon entre la distancia (d)recorrida por un automóvil y el tiempo (t)empleando velocidad (v) es una razón entre distancia y el tiempo y de valor de su velocidad v=d/t
Answer:
V = d / t
Step-by-step explanation:
La velocidad se define como la relación entre la diatancia cubierta por un cuerpo y el tiempo necesario para cubrir esa distancia.
Si el tiempo empleado se da como (t)
La distancia recorrida se da como (d)
Podemos escribir la velocidad (V) en términos de disance y tiempo como;
V = d / t
List the first three terms of this sequence: an = 3 • 5n – 1
Answer:
1st term = 14
2nd term = 29
3rd term = 44
Step-by-step explanation:
1st term = 3 x (5 x 1) - 1
= 3 x 5 - 1
= 15 - 1 = 14
2nd term = 3 x (5 x 2) - 1
= 3 x 10 - 1
=30 - 1 = 29
3rd term = 3 x (5 x 3) -1
= 3 x 15 - 1
= 45 - 1 = 44
