Answer:
Regroup Terms: cos 45 tan 45x + tan^2 tan 30x, 60
Answer:
[tex]\frac{1}{\sqrt{2}}+\frac{3}{\sqrt{3}}[/tex] , by the way, the simplified is [tex]2.439157589[/tex]
Step-by-step explanation:
I included a chart so next time you don't need to worry
tan( 45 degrees) = 1cos( 45 degrees) = [tex]\frac{1}{\sqrt{2}}[/tex] tan( 30 degrees) = [tex]\frac{1}{\sqrt{3}}[/tex] tan squared (60 degrees) is the same as saying square the answer of tan (60 degrees). So tan( 60 degrees) = [tex]\sqrt{3}[/tex] , so squarehelp help help help help help help help pls

The amount of paper that the copy shop used this month was a 25% increase of the amount of paper they used last month. This month, there were 78 copies made. How many copies were made last month?
Answer:
98 copies
Step-by-step explanation:
25% of 78 is 19.5
19.5 + 78 = 97.5
Because there can't be half of a copy we round up based on the decimal. Therefore the answer would 98 copies.

-c+1 > 2 now this one
-c + 1 > 2
-c > 2-1 Move 1 to subtract.
-c > 1
c < -1 When the coefficient is negative, moving the negative to another side as changing the sign of Inequality to opposite.
Thus, the answer is c < -1

X^5/6 * x^1/3 can someone please solve this ?
Point-slope form
Complete the point-slope equation of the line through (-4, 8) and (4,4).
Use exact numbers.
WHOEVER ANSWERS RIGHT GETS BRAINIST
There are actually two correct answers, one of them is y-4=-0.5(x-4)
First of all, the slope-intercept that can be derived from the points (-4,8) and (4,4) is y=[tex]-\frac{x}{2} +6[/tex], with -0.5 being the slope. To bring this to point-slope form, you must signify the slope and the coordinate intersection. Since there are two coordinates, there are actually two point-slope equations.

Step-by-step explanation:
A new shopping mall records 120 total shoppers on their first day of business. Each day after that, the number of shoppers is 10, percent more than the number of shoppers the day before. What is the total number of shoppers that visited the mall in the first 7 days?
Answer:
1138
Step-by-step explanation:
From the information given:
We can represent it perfectly in an exponential form:
[tex]m = p(q)^x[/tex]
where;
p = initial value = 120
q = base of the exponential form
q = 1 + r
here; r = rate in decimal = 10% = 0.1
Then q can now be = 1 + 0.1 = 1.1
Replacing it into the exponential form, we get:
[tex]m = 120(1.1)^x[/tex]
where;
x = number of days and m = number of shoppers
Thus:
For the first day:
[tex]m = 120(1.1)^x[/tex]
m = 120
For the second day:
[tex]m = 120(1.1)^1[/tex]
m = 132
For the third day:
[tex]m = 120(1.1)^2[/tex]
m = 145.2
For the fourth day
[tex]m = 120(1.1)^3[/tex]
m = 159.72
For the fifth-day
[tex]m = 120(1.1)^4[/tex]
m = 175.692
For the sixth-day
[tex]m = 120(1.1)^5[/tex]
m = 193.2612
For the seventh-day
[tex]m = 120(1.1)^6[/tex]
m = 212.58732
Thus; the total numbers of shoppers for the first 7 days is:
[tex]= 120+ 132 + 145.2 + 159.72 + 175.692+193.2612+212.58732[/tex]
= 1138.46052
≅ 1138
Learning task 2
A. Solve the systems of equations by a) graphing b) elimination c) substitution
Eq. 1: 2x - 3y = -1; Eq. 2: y = x - 1
B. Solve the problem using any method.
The sum of two numbers is 32 and the difference is 2. Find the numbers
The given equations are
[tex]2x-3y=-1\cdots(i) \\\\y=x-1\cdots(ii)[/tex]
(a) Solution by graphing both the equations:
Graph for both the equations (i) and (ii) are in the figure. The point of intersection of both the graph is the solution of the equations.
From the graph, the point of intersection is (4,3)).
Hence, the required solution is (4,3).
(b) Solution by elimination method:
Equations (ii) can be written as -x+y=-1, now multiply it by 2, we have
[tex]-2x+2y=-2\cdots(iii)[/tex]
Add equations (i) and (iii), we have
2x-3y=-1
-2x+2y=-2
__________
[tex]\Rightarrow -3y+2y=-1-2\\\\ \Rightarrow -y=-3\\\\ \Rightarrow y=3.[/tex]
Putting the value of y=3 in equation (i), we have
[tex]2x-3\times 3=-1 \\\\\Rightarrow 2x=-1+9=8 \\\\\Rightarrow x=8/2=4[/tex]
Hence, the required solution is (4,4).
(c) Solution by substitution method:
Substituting the value of y from equation (ii) to equation (i), we have
[tex]2x-3(x-1)=-1 \\\\\Rightarrow 2x-3x+3=-1 \\\\\Rightarrow -x=-1-4=-4 \\\\\Rightarrow x=4[/tex]
Putting the value of x=4 in equation (i), we have
[tex]y=4-1=3[/tex].
Hence, the required solution is (4,3).
Which expression is equivalent to 8x - 12y + 32?
A. 16(0.5x 4y +32)
B. 16(0.5x - 0.75y + 32)
C. 16(0.5x - 0.75y + 2)
D. 16(0.5x + 4y +2)
Answer:
It's the third
16(0.5x - 0.75y +2)
Step-by-step explanation:
You just divide everything by 16
8x/16= 1/2x=0.5x
-12y/16 = -3/4x=-0.75x
32/16=2
Hope this helps, have an amazing day ^_^
