Use trigonometry to find L.
Tangent = opposite over adjacent on any right triangle.
tan(L) = 18/23
Take the inverse on both sides.
arctan(tan(L)) = arctan(18/23)
L = 38.0470425318
L = 38.05°
Done.

What is f(x)=|x| when it is vertically scaled by a factor of 4, reflection in the y axis, and translated 7 units up and 1 unit to the right?
Answer:
(1,3)
Step-by-step explanation:
starting at (0,0)
vertically scaled by 4 - go up four (0,4)
reflected on y axis - negative the four (0,-4)
translated 1 to the right and 7 up - go up 7 and to the right 1 (1,3)
hope this helps :)

the answer on there is wrong
Answer:
[tex]\displaystyle -0.\overline{37}=-\frac{37}{99}[/tex]
Step-by-step explanation:
Convert a Repeating Decimal to a Fraction
We need to convert the following decimal to a fraction:
[tex]-0.\overline{37}[/tex]
Let's call x to the given number:
[tex]x=-0.\overline{37}[/tex]
The number has two repeating (periodic) decimals, thus we multiply by 100:
[tex]100x=-37.\overline{37}[/tex]
Note the decimals continue to repeat exactly like the original number.
Subtracting both expressións, the repeating decimals are simplified:
[tex]100x - x = -37[/tex]
Operating:
99x=-37
Dividing by 99:
[tex]\displaystyle x=-\frac{37}{99}[/tex]
The fraction cannot be simplified, thus:
[tex]\mathbf{\displaystyle -0.\overline{37}=-\frac{37}{99}}[/tex]

Johnna has $440 in her savings account the first week. She deposits $65 in her account every week. How much money will Johnna have in her savings account in the 25th week?
she will have $2065 in her savings account after the 25th week.
Answer:
2,065
Step-by-step explanation:
First you need to figure out 65 times 25 because she puts $65 into her account every week so you need to multiply by 25 because you have to figure out how much money she will have on the 25th week so:
$65 * 25 = 1,625
then you need to add that to 440 because ahe still only has 440 in her account until now so, in conclusion, she has 2,065 because:
$65 * 25 = $1,625 + $440 = 2,065

Answer:
7. -
a. 3.5 or 7/2 hours
b. 24.5
c. After 7 hours (and at the beginning when t=0)
8. -
a. 4 seconds
b. 1 second
c. 54 meters
Step-by-step explanation:
7. M(t)=-2t^2+14t
M’(t)=-4t+14
a)
-4t+14=0
4t=14
2t=7
t=7/2
b) M(7/2)=24.5
c)
M(t)=0
-2t^2+14t=0
t^2-7t=0
t(t-7)=0
t=0, 7
8.
a)
h(t)=0
-6t^2+12t+48=0
t^2-2t-8=0
(t-4)(t+2)=0
t=-2, 4
t=4
b)
h(t)=-6t^2+12t+48
h’(t)=-12t+12
h’(t)=0
-12t+12=0
12t=12
t=1
c) h(1)=54

The volume V (in cubic feet) of a rectangular room can be modeled by V(x)= 2x^3-14x^2+12x, where x is the length (in feet) if the room. Factor the function. Use your factorization to determined the values of x for which the model makes sense
Answer:
The values of x for which the model makes sense is [tex]x\ge 6\,ft[/tex].
Step-by-step explanation:
From statement we have the following expression for the volume of the rectangular room is:
[tex]V(x) = 2\cdot x^{3}-14\cdot x^{2}+12\cdot x[/tex] (1)
Where:
[tex]V[/tex] - Volume of the rectangular room, measured in cubic feet.
[tex]x[/tex] - Length of the room, measured in feet.
By Algebraic means we factorize the polynomial:
[tex]V(x) = x\cdot (2\cdot x^{2}-14\cdot x +12)[/tex]
[tex]V(x) = x\cdot (x-6)\cdot (x-1)[/tex]
Given that both volume and length must be positive variables, then the following conditions must be satisfied:
[tex]x \ge 0\,ft\,\land\,x\ge 6\,ft\,\land\,x\ge 1\,ft[/tex]
Then, the values of x for which the model makes sense is [tex]x\ge 6\,ft[/tex].

8. What is the solution of the equation 4x + 12 = 48 ?
a) x= 9
b) x= 15
c) x= 144
d) x= 240
Answer:
A) x=9
Step-by-step explanation:
48-12=36.
36/4=9
More detailed explanation:
4x+12=48
-12 -12
4x = 36
/4 /4
x = 9
The solution of the equation is, x = 9.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The equation is,
⇒ 4x + 12 = 48
Now, We can solve the equation for value of x as;
⇒ 4x + 12 = 48
Subtract 12 both side, we get;
⇒ 4x + 12 - 12 = 48 - 12
⇒ 4x = 36
Divide by 4;
⇒ 4x/4 = 36/4
⇒ x = 9

Would the answer of
-9/16+9/8
Be positive or negative? Explain why or why not.
This is a personal question!
Answer:
It would be positive
Step-by-step explanation:
To do anything with fractions you need to find a common denominator, in this case lets say its 128. the 9 in the negative side would need to be multiplied by 8 like it's denominator making it 72. You would do the same to the other fraction giving you the fractions -72/128 and 144/128 from here you add to get 72/128 which is positive
Answer:
positive
Step-by-step explanation:
-9/16= -0.5625
9/8= 1.125
-9/16+9/8= -0.5625 + 1.125(in the addition of opposite signs u should figure out the largest num and should substract the other numa nd assign the sign of the biggest nym)
=0.5625
the reason
+ * + = +
- * - = +
+ * - = -
+/+ =+
- / - = -
-/ + = -
