Since this is a right triangle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.
Remember: SOH-CAH-TOA
Looking from the angle, we know the opposite side and the hypotenuse. Therefore, we should use the sine function.
sin(x) = 21/40
x = sin^-1(21/40)
x = 32 degrees

1b).The function will shift 3 units to the left, stretched in the y direction by a scale factor of 3, and shift up 2 units.
2a). The function will shift 2 units to the left, reflect over the x axis, and shift 2 units down.
2b) The function will stretched in the y direction by a scale factor of -2 and shift the function up 3 units.

Answer:
1a. translation right 5, down 4
1b. vertical stretch ×3, translation left 3, up 2
2a. translation left 2, down 2
2b. reflect in x, vertical stretch ×2, translation up 3
3. f(x) = -4/(x+5)+4
4. f(x) = 1/2√(3(x +3)) -4
Step-by-step explanation:
Transformations of functions can be decoded by considering the transformation ...
g(x) = a·f((x-h)/b) +k
The transformations here are ...
vertical stretch by a factor of 'a'horizontal stretch by a factor of 'b'right shift by h unitsup shift by k unitsNote that either 'a' or 'b' can be a fraction less than 1, which results in a transformation usually described as a compression (not a stretch). If either of these is negative, then a reflection over the x-axis (a<0) or y-axis (b<0) is also involved. The stretch (or compression) and/or reflection is applied before the translation the way this is written.
_____
1a. translation right 5, down 4
1b. vertical stretch by a factor of 3, translation left 3, up 2
__
2a. translation left 2, down 2
2b. reflected across the x-axis, vertically stretched by a factor of 2, translated up 3
__
3. a=4, b=-1, h=-5, k=4
f(x) = -4/(x+5)+4
__
4. a=1/2, b=1/3, h=-3, k=-4
f(x) = 1/2√(3(x +3)) -4

If a = -5, then 2a = -10
Answer:
That is correct
Step-by-step explanation:
To get from a to 2a we multiply by 2, so we also need to multiply -5 by 2:

What is the area of the trapezoid below
Answer:
A = 60 in ^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2) h where b1 and b2 are the lengths of the bases
The bottom base is 8+2+2 = 12
A = 1/2 ( 8 + 12) *6
A = 1/2( 20)6
A = 60 in ^2
Rose’s checking account has a balance of Negative 54 dollars. She makes no more withdrawals but deposits $15 per day in her account over the next five days. On the sixth day, she makes no deposits, but the bank charges a maintenance fee of $5. What is the balance in her account on the sixth day? $16 $26 $124 $134
Answer:
16
Step-by-step explanation:
Her account balance on the sixth day is sixteen. This is because -54 +75 is 21 then you subtract 5 and get 16. (15 times 5 is 75)
Answer:
16
Step-by-step explanation:
Starting balance: -54
Deposits +15

for a total of +75
-54+75 = 21
Maintenance fee: - 5

1. Shoe B was created by rotating Shoe A counterclockwise about a fixed point. How many degrees was the shoe rotated?
Answer:
90°
Step-by-step explanation:
Rotation counterclockwise means the rotating an object over a fixed point in the opposite direction of our normal wall clock.
To get exact position of shoe B, shoe A would be rotated in about 90° in the opposite direction of a clock.
Thus, shoe A was rotated 90° about a fixed point to create shoe B.

Write an absolute value equation to salsify the given solution set shown on a number line -1/2 1/2 a Plz help me
Answer:
The absolute value equation is |x| =[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The standard form of absolute value equation is |x-a| =b
Where 'b' is distance from midpoint to one of the end point.
'a' is midpoint.
Here we need to write absolute value equation for the solution -[tex]\frac{1}{2}[/tex] to [tex]\frac{1}{2}[/tex] .
The midpoint of -[tex]\frac{1}{2}[/tex] to [tex]\frac{1}{2}[/tex] is 0. Because [tex]\frac{\frac{-1}{2} +\frac{1}{2} }{2} =0[/tex]
The distance from 0 to [tex]\frac{1}{2}[/tex] is [tex]\frac{1}{2}[/tex]
The absolute value equation is
|x-0 | =[tex]\frac{1}{2}[/tex]
We can simplify it as

Matt makes $80 a month mowing lawns. His friend James also mows lawns, but he makes x dollars less per month than Matt does. James makes a total of $816 per year. How much less each month does James make than Matt?
Equation: 12(80 – x) = 816
Answer:
$12 less each month
Step-by-step explanation:
Find how much less James makes by solving for x in the equation:
12(80 - x) = 816
960 - 12x = 816
-12x = -144
x = 12
So, James makes $12 less each month than Matt does.

Chris rents a car for a total of £375. The rental charges are £150 for the first day and £75 per day after that. For how many days did Chris rent the car? You must show your working.
I have attempted the question (see picture), but I've only managed to get 2/3 marks!!! Please help! (I will award brainliest btw) TIA ;-)

Answer:
4 days
Step-by-step explanation:
The total charges can be modeled by ...
c = 75d + 75 . . . . . . charges for d days
Filling in the given charge, we find ...
375 = 75d +75
300 = 75d . . . . . . . subtract 75
4 = d . . . . . . . . . . divide by 75
Chris rented the car for 4 days.
Answer:
4 DAYS!! THIS GETS ALL 3 MARKS!!!
Step-by-step explanation:
COPY AND PASTE THIS I USED IT EVEN THO ITS LONG <333 IT GETS THE 3 MARKSChris rents a car for a total of £375. The rental charges are £150 for the first day and £75 per day after that. For how many days did Chris rent the car? You must show your working.
£375.00 - £150.00 = £225.00
£225.00 - £75.00 = £150.00
£150.00 - £75.00 = £75.00
£75.00 - £75.00 = £00.00
= Chris rented the car for 4 days
225.00 ÷ 75 = 3
3 days + 1 days = 4 days
he total charges can be modeled by ...
c = 75d + 75 . . . . . . charges for d days
Filling in the given charge, we find ...
375 = 75d +75
300 = 75d . . . . . . . subtract 75
4 = d . . . . . . . . . . divide by 75
Answer:4 days

In a class of 25 students
the mean height of the 15 girls is 1.65 metres
the mean height of all 25 students is 1.682 metres.
Work out the mean height of the boys.
The mean height of the boys will be 1.73m.
What is mean?Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.
Given that:-
In a class of 25 students, the mean height of the 15 girls is 1.65 meters the mean height of all 25 students is 1.682 meters.If the mean height of 15 girls is 1.65m, the sum of the girls’ heights is 15×1.65 = 24.75m.
If the mean height of 10 boys is x meters, the sum of the boys’ heights is 10x m. The sum of all 25 students’ heights is
25×1.682=42.05m.
The mean height of the boys.
24.75+10x=42.05,
x =(42.05-24.75)/10
x =1.73m,
Therefore the mean height of the boys will be 1.73m.
