Answer:
see below
Step-by-step explanation:
tan ^2 x -sin ^2 x = tan ^2x sin ^2x
tan = sin / cos
sin ^2 x / cos ^2 x -sin ^2 x = sin ^2 x / cos ^2 x * sin^2 x
Multiply each side by cos ^2
cos ^ x (sin ^2 x / cos ^2 x -sin ^2 x) = cos ^2 x(sin ^2 x / cos ^2 x * sin ^2x)
sin ^2 x - cos ^2 x sin ^2 x = sin ^2 x * sin ^2x
Factor out sin ^2 x
sin ^2 x(1 - cos ^2 x) = sin ^2 x * sin^2 x
We know that 1 - cos ^2 x = sin ^2 x
sin ^2 x(sin ^2 x) = sin ^2 x * sin^2 x
A copy shop charges $0.20 per photocopy for orders of up eight copies. Which graph represents this relation?
Answer:
D
Step-by-step explanation:
This would be a discrete graph ( points) not a solid line.
This eliminates A and C
1 copy costs 20 cents
8 copies costs 1.60
The number of copies is the independent variable, so it should be plotted on the x axis
Answer:
The answer is D in this question, if you are on plato it may be different so just make sure the graph on choice d on here matches on your test
Step-by-step explanation:
Find y' if x = cos(y).
1. Solve for y (complex solution)
y=−iln(x2−1+x)+2πn1, n1∈Z
y=−iln(−x2−1+x)+2πn2, n2∈Z
2. Solve for y (Easier)
y=−arccos(x)+2πn1, n1∈Z
y=arccos(x)+2πn2, n2∈Z, ∣x∣≤1
To run a mile, Jamal must run 4 laps around the track. His goal is to run 3 miles. Jamal has run 9 laps so far.
Answer:
1 mile = 4 laps
3 miles = 12 laps
9/4 = x /1
9/4 = 2.25
he has run 2.25 miles = 9 laps
he needs to run 0.75 miles = 3 laps
f(x)= -5x+9 ; reflection in the y-axis a.g(x)=5x-9 b.g(x)=5x+9 c.g(x)=9x-5 d.g(x)=5x-5
Explanation:
When we reflect over the vertical y axis, every negative x value becomes positive and vice versa. So we effectively replace x with -x like so
f(x) = -5x+9
f(-x) = -5(-x)+9 ... replace every x with -x
f(-x) = 5x+9
g(x) = 5x+9
A point like (1,4) on f(x) will reflect over to (-1,4) on g(x). If we apply this to every point on f(x), then all of f(x) will reflect to g(x).

What is 1 5/8 times 2 2/3
Answer:
Step-by-step explanation:
Convert mixed fraction to improper fraction.
[tex]1\frac{5}{8}*2\frac{2}{3}=\frac{13}{8}*\frac{8}{3}\\\\\\=\frac{13}{3}\\\\\\=4\frac{1}{3}[/tex]
Answer:
4 1/3
Step-by-step explanation:
1 5/8 × 2 2/3
First we turn it into an improper fraction:
1 5/8 × 2 2/3 = 13/8 × 8/3
Now we multiply them across:
13/8 × 8/3 = 104/24
Now we simplify:
104/24 = 13/3
because 3 × 8 = 24 and 13 × 8 = 104
Now we simplify again because we can't leave it as an improper fraction. So we turn it into a mixed fraction:
13/3 = 4 1/3
4 1/3 is answer

Answer:
a) 08:04
b) 07:00
c) 14 minutes
Step-by-step explanation:
a) According to the timetable, a bus that leaves at 07:54 from Hope Street will arrive at School Rock at 08:04.
b) Since Jo needs to be at the school at 8 am, she can't arrive at a time that is past 8. This means that the latest time to catch the bus station is 07:00.
c) You have to subtract the time at which you reach the destination by the time at which you leave your starting time. It takes the bus 14 minutes to travel from the bus station to School Road.
07:14 - 07:00 = 00:14
A company makes a profit of $7 per software program and $8 per video game. The company can produce at most 90 software programs and at most 80 video games per week. Total production cannot exceed 120 items per week. How many items of each kind should be produced per week in order to maximize the profit? Use linear programming to solve. Show all your work.
Answer:
930 dollars
Step-by-step explanation:
Let software programs = S
Video game = V
Given that a company makes a profit of $7 per software program that is, 7S and $8 per video game that is, 8V. The company can produce at most 90 software programs and at most 80 video games per week. Since the Total production cannot exceed 120 items per week.
How many items of each kind should be produced per week in order to maximize the profit?
The to get profit P
P = 7S + 8V
Since the profit on video game is higher, we will give maximum production to video game. Therefore,
P = (30 × 7) + ( 8 × 90)
P = 210 + 720
P = 930 dollars
what is 75% of £60?
Answer:
45
Step-by-step explanation:
75x60=4500
4500/100=45
Answer:
£45
Step-by-step explanation:
Take 75% of 60: [tex]\frac{75}{100}[/tex] × [tex]\frac{60}{1}[/tex] = [tex]\frac{4500}{100}[/tex] To simplify, look at the denominator. There's a 100 in the denominator. And, 100 has two zeros at the end. In the numerator, we have 4500. 4500 has two zeros in the end as well. First, cancel out the two zeros in 100 to make it 1. Then, to make the fraction even, cancel out the two zeros in 4500 to make it 45. It should now look like this: [tex]\frac{45}{1}[/tex]. We know any number over 1 is itself. So, [tex]\frac{45}{1} = 45[/tex]Therefore, 75% of £60 is £45.

Can The intersection of two planes can be a ray.
Answer: Either the plane and the ray perfectly coincide in which case there is an infinity of solutions or the ray is away from the plane in which case there is no intersection. Generally in a C++ implementation, when the denominator is lower than a very small value, we simply return false (no intersection was found).

$11.63 per portion
The word demographic comes from ancient Greece. Demos means people. Graphic means picture. Based on the video and this information, which thing below is most likely shown on a demographic map? countries, population, continents, or leaders
Answer:
Population
Step-by-step explanation:
If we know the root Demos means people and graphic means picture, let's put the english terms together.
Demo graphic
People graphic
So this is going to be a "People Graphic." So we know that Countries and Continents are ruled out.
Now I just used logic to figure out whether it's population or leaders. A map showing the leaders of something would be useless, but a map showing population is useful. So I assumed that a Demographic map shows population (I also looked it up to check, and yes this is right.)
Hope this helped!
Answer:

Given T (x,y) = (x+5,y+4) and the point P (2,3) what is T (P)
Answer:
(7, 7 )
Step-by-step explanation:
The translation rule
(x, y ) → (x + 5, y + 4 )
Means add 5 to the original x- coordinate and add 4 to the original y- coordinate, thus
(2, 3 ) → (2 + 5, 3 + 4 ) → (7, 7 )

Leslie was able to map \overline{ST} ST start overline, S, T, end overline onto \overline{QR} QR start overline, Q, R, end overline using a rotation and dilation. Leslie concluded: "I was able to map \overline{ST} ST start overline, S, T, end overline onto \overline{QR} QR start overline, Q, R, end overline using a sequence of rigid transformations, so the figures are congruent." What error did Leslie make in her conclusion?
The fact that Leslie used a dilation is where she made the mistake. A dilation either shrinks or enlarges a figure. So it made segment ST either larger or smaller to be able to fit to segment QR.
But congruent segments are always the same length. So there's no way that a dilation can be involved. Only rigid transformations of translations (aka shifting), reflections, and rotations are allowed. A dilation is not a rigid transformation.

Answer:
[tex]\Huge \boxed{{9}}[/tex]
Step-by-step explanation:
Let the age of Darrell be x.
Let the age of Bryce be y.
x = y + 8
xy = 153
Substitute x = y + 8 in the second equation.
(y+8)y = 153
Solve for y.
y² + 8y = 153
Subtract 153 from both sides.
y² + 8y - 153 = 0
Factor left side.
(y-9)(y+17) = 0
Set factors equal to 0.
y - 9 = 0, y = 9
y + 17 = 0, y = -17
The value of y has to be positive, so y = 9.
Substitute y = 9 in the first equation.
x = 9 + 8
x = 17
Darrell is 17 years old.
Bryce is 9 years old.
Answer:
[tex]\huge\boxed{9\ years}[/tex]
Step-by-step explanation:
Let Darrel's Age be x and Bryce's Age be y
Condition 1:
x = 8 + y
Condition 2:
xy = 153
Put the 1st equation in the second one
(8+y)y = 153
y²+8y-153 = 0
y²+17y-9y-153 = 0
y(y+17)-9(y+17) = 0
(y-9)(y+17) = 0
Either,
y-9 = 0 OR y+17 = 0
y = 9 OR y = -17 [Contrary to be given, Age can never be negative]
So, y = 9
And
Bryce's Age = 9 years
