The unknown sides of the right angle triangle using trigonometric ratios are as follows;
PR = 13.2 units
RQ = 17.6 units
What is a right angle triangle?
A right angle triangle is a triangle that has one of its angles as 90 degrees.
The sides of the triangle can be found using trigonometric ratios.
Therefore,
sin 37° = opposite / hypotenuse
sin 37° = PR / 22
cross multiply
PR = 22 sin 37
PR = 22 × 0.60181502315
PR = 13.2399305093
PR = 13.2 units
cos 37 = adjacent / hypotenuse
cos 37 = RQ / 22
RQ = 22 cos 37
RQ = 17.569981221
RQ = 17.6 units

Question 2 of 10
Which of the following geometric objects occupy one dimension?
Check all that apply.
A. Line
B. Triangle
C. Plane
D. Segment
E. Ray
F. Point
Answers
A. Line
D. Segment
E. Ray
Step-by-step explanation:Math dimensions include length, width, and height (in that order). The dimension that an object occupies is dependent on how many different measurements, aka dimensions, an object has.
0th Dimension
The first dimension is actually the zeroth dimension. This dimension includes objects that do not have any measurements. A point does not have a length because it only occupies one spot on a plane.
The 0th dimension includes:
Point1st Dimension
The next dimension, the 1st dimension, has only length. This means the object can travel across the x-axis, but it can only go in one direction.
The 1st dimension includes:
LineSegementRay2nd Dimension
For this question, the last dimension is the 2nd dimension. The 2nd dimension has both length and width. This means that the object occupies both the x and y-axis.
The 2nd dimension includes:
TrianglePlane3rd Dimension
The 3rd dimension is not included in the question or the answer choices but is still important. The 3rd dimension has length, width, and height. This occupies the x, y, and z-axis and cannot be graphed on a regular geometric plane. The 3rd dimension is graphed in a geometric space.
The 3rd dimension includes:

A The function has three nonreal zeros.
B The function has three real zeros.
C The function has two real zeros and one nonreal zero.
D The function has one real zero and two nonreal zeros.
Answers
Using the Factor Theorem, it is found that the correct option regarding the complex zeros of f(x) is given by:
D The function has one real zero and two nonreal zeros.
What is the Factor Theorem?The Factor Theorem states that a polynomial function with roots [tex]x_1, x_2, \codts, x_n[/tex] is given by:
[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]
In which a is the leading coefficient.
In this problem, the function is given by:
f(x) = x³ - 3x² + 16x + 48.
Using a calculator, the roots are given by:
[tex]x_1 = -1.89767, x_2 = 2.44884 + 4.39288i, x_3 = 2.44884 - 4.39288i[/tex]
The first root is real, while the second and third are complex(nonreal), hence option D is correct.

Please help with this! I have to reflect over the x axis by the way
Answers
Answer:
T' = (-8, 8)
U' = (2, 8)
V' = (-8, 7)
Step-by-step explanation:
reflection over x axis means we change the sign of the y coordinate and nothing else
T = (-8, -8)
y coordinate = -8, change the sign to get 8
T' is thus (-8, 8)
U = (2, -8)
y coordinate = -8, y' = 8
U' = (2, 8)
V = (-8, -7)
y' = 7
V' = (-8, 7)

Bulb box and carton both are of cuboidal shape.
For bulb box the dimensions are:
l = 5 cm, w = 4 cm, h = 4 cm[tex]V_{Bulb\: box} =lwh[/tex][tex]\implies V_{Bulb\: box} =5(4)(4)[/tex][tex]\implies V_{Bulb\: box} =80\: cm^3[/tex]For Carton the dimensions are:
l = 50 cm, w = 20 cm, h = 20 cm[tex]V_{Carton} =lwh[/tex][tex]\implies V_{Carton} =50(20)(20)[/tex][tex]\implies V_{Bulb\: box} =20,000\: cm^3[/tex]To find the number of bulbs packed in the carton, divide the [tex]V_{Carton}[/tex] by [tex] V_{Bulb\: box}[/tex]
[tex] Number \:of \:bulbs =\frac{V_{Carton}}{V_{Bulb\: box}}[/tex][tex] \implies Number \:of \:bulbs =\frac{20,000}{80}[/tex][tex] \implies Number \:of \:bulbs = 250[/tex]So, 250 bulbs will be packed in one carton.
John is making apple pies and apple cobblers to sell at the farmer’s market. A pie uses 4 cups of apples and 3 cups of flour. A cobbler uses 2 cups of apples and 3 cups of flour. When John sells the pies and cobblers at the farmer’s market, he will make $3.00 profit per pie and $2.00 profit per cobbler. Let x = the number of pies John makes. Let y = the number of cobblers John makes. Interpret the meaning of the vertex with the maximum profit in context of john’s baking.
Answers
Step-by-step explanation:
there are some pieces of information missing like the price of apples and flour. or the selling prices. or any restrictions like a fixed budget to buy ingredients or how many pies and cobblers he can make in a certain available time.
all we can say based on the given information :
one pie = 4a + 3f (a = apples, f = flour)
one cobbler = 2a + 3f
P(x, y) = 3x + 2y =
= x(selling price - 4a - 3f) + y(selling price - 2a - 3f)
the max. of P(x, y) is the maximum profit by selling pies and cobblers, which is without any further information +infinity.
the more pies and cobblers he sells, the bigger the profit - no limit.

NO LINKS!!!! Exponential Growth and Decay Part 2
Answers
Problem 4
a = 10800 = initial populationb = 1 + r = 1 + (-0.025) = 0.975 is the decay factorThe template of [tex]y = a*b^x[/tex] becomes [tex]y = 10800*0.975^x[/tex] to represent the exponential function.
x = number of years since 2002y = populationWe want to know when the population reaches half of 10800, so we want to know when the population is 10800/2 = 5400
Plug in y = 5400 and solve for x.
[tex]y = 10800*0.975^x\\\\5400 = 10800*0.975^x\\\\0.975^x = 5400/10800\\\\0.975^x = 0.5\\\\\log(0.975^x) = \log(0.5)\\\\x\log(0.975) = \log(0.5)\\\\x = \log(0.5)/\log(0.975)\\\\x \approx 27.377851\\\\x \approx 28\\\\[/tex]
I rounded up to the nearest whole number because x = 27 leads to y = 5452, which is not 5400 or smaller.
Luckily, x = 28 leads to y = 5315 which gets over the hurdle of being 5400 or smaller.
Add 28 years onto the starting year 2002 and we get to 2002+28 = 2030
The population reaches half of its original amount in the year 2030.

Problem 5
a = 28750 = starting value for the carb = 1 + r = 1 + (-0.12) = 0.88 = decay factorIf the car loses 12% of its value each year, then it keeps the remaining 88%
Plug those values into [tex]y = a*b^x[/tex].
We find the equation is [tex]y = 28750*0.88^x[/tex] where,
x = number of years since 2012y = car's valueReplace y with 10,000 and solve for x.
[tex]y = 28750*0.88^x\\\\10000 = 28750*0.88^x\\\\0.88^x = 10000/28750\\\\0.88^x \approx 0.347826\\\\\log(0.88^x) \approx \log(0.347826)\\\\x\log(0.88) \approx \log(0.347826)\\\\x \approx \log(0.347826)/\log(0.88)\\\\x \approx 8.261168\\\\x \approx 9\\\\[/tex]
Like in the previous problem, we round up so we clear the hurdle.

Exponential Function
General form of an exponential function: [tex]y=ab^x[/tex]
where:
a is the initial value (y-intercept)b is the base (growth/decay factor) in decimal formx is the independent variabley is the dependent variableIf b > 1 then it is an increasing function
If 0 < b < 1 then it is a decreasing function
Question 4Given:
a = 10,800b = decrease of 2.5% = 0.975x = time (in years)y = populationAs the population is decreasing by 2.5% each year, the population will be 100% - 2.5% = 97.5% of the previous year. Therefore, the base is 0.975.
Final equation: [tex]\large \text{$ y=10800(0.975)^x $}[/tex]
Half of population: 10800 ÷ 2 = 5400
[tex]\large \begin{aligned}y & =5400\\\implies 10800(0.975)^x & =5400\\(0.975)^x & = \dfrac{5400}{10800}\\(0.975)^x & = 0.5\\\ln (0.975)^x & = \ln 0.5\\x \ln 0.975 & = \ln 0.5\\x & = \dfrac{\ln 0.5}{\ln 0.975}\\x & = 27.377785123\end{aligned}[/tex]
2002 + 27.37785... = 2029.37785...
Therefore, the population will reach half during 2029 (by 2030).
Question 5Given:
a = 28,750b = decrease of 12% = 0.88x = time (in years)y = value (in dollars)As the value is decreasing by 12% each year, the value will be 100% - 12% = 88% of the previous year. Therefore, the base is 0.88.
Final equation: [tex]\large \text {$ y=28750(0.88)^x $}[/tex]
Find when the car is worth $10,000:
[tex]\large \begin{aligned}y & = 10000\\\implies 28750(0.88)^x & = 10000\\(0.88)^x & = \frac{10000}{28750}\\(0.88)^x & = \frac{8}{23}\\\ln (0.88)^x & =\ln \left(\frac{8}{23}\right)\\x \ln (0.88) & =\ln \left(\frac{8}{23}\right)\\x & =\dfrac{\ln \left(\frac{8}{23}\right)}{\ln (0.88)}\\x & = 8.26116578\end{aligned}[/tex]
2012 + 8.26116578.. = 2020.26116578..
Therefore, the value of the car will reach $10,000 during 2020 (by 2021).

The area of a rectangle is 24 cm² and the perimeter is 22 cm .What is the lenth and width of this rectangle?
Answers
Step-by-step explanation:
length × width = 24
2×length + 2×width = 22
length + width = 11
length = 11 - width
this we use in the first equation again :
(11 - width) × width = 24
11×width - width² = 24
width² - 11×width + 24 = 0
the general solution to an quadratic equation :
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = width
a = 1
b = -11
c = 24
and so we get
width = (11 ± sqrt((-11)² - 4×1×24))/2×1) =
= (11 ± sqrt(11² - 96))/2 = (11 ± sqrt(121-96))/2 =
= (11 ± sqrt(25))/2 = (11 ± 5)/2
width1 = (11 + 5)/2 = 16/2 = 8 cm
width2 = (11 - 5)/2 = 6/2 = 3 cm
and teenaged to this is then
length1 = 11 - width1 = 11 - 8 = 3 cm
length2 = 11 - width2 = 11 - 3 = 8 cm
so, it is clear. one dimension has to be 8 cm, and the other one 3 cm. it does not matter which is which.
