Answer:
Principal amount (P) = $6000
Rate (R) = 12%
Time = 2 years
Simple interest, I = P X R X T / 100
= 6000 X 12 X 2 / 100
= 144000 / 100
= 1440
=> Simple interest, I = $1440
Amount they would owe at the end of 2 years,
= P + I
= 6000 + 1440
= $7440
cos (x/2) = -sqrt2/2 in (0,360) looking for two values ?? Can someone please help me I can’t seem to figure out how to solve this problem, I’m looking at other examples but I’m still confused please help
Answer:
135° and 225°
Step-by-step explanation:
basically you want to find the value of x between 0 and 360 in this equation
cos x/2 = -(√2)/2
assume x/2 as n, so
cos n = -(√2)/2
n = 45°
then remember the quadrant system
0-90 1st quadrant, all is POSITIVE
90-180 2nd quadrant, only SIN has positive value
180 - 270 3rd quadrant, only TAN has positive value
270 -360 4th quadrant, only COS positive here.
so if you try to find negative value look into 2nd and 3rd quadrant that related 45° to x-axis (0°or 180°)
so the value of x is
180 - 45 = 135° (2nd quadrant) and
180 + 45° = 225° (3rd quadrant)
How are the equations of a parabola, ellipse, and hyperbola created?
Answer:
ellipses and hyperbolas as a simple form has the x-axis as principal axis and the origin (0,0) as center. If it's a circle, c = 0 so a2 = b2. And for the parabola, the standard form has the focus on the x-axis at the point (a, 0) and the directrix the line with equation x = −a.

What is the vertical asymptote for the reciprocal of y=8x-4
Answer:
The vertical asymptote for the reciprocal of y=8x-4 is [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given Equation : [tex]y = 8x-4[/tex]
Reciprocal of given equation =[tex]\frac{1}{y}=\frac{1}{8x-4}[/tex]
Now to find the vertical asymptote
[tex]\frac{1}{y}=\frac{1}{8x-4}[/tex]
Equate denominator to 0
8x-4=0
8x=4
[tex]x=\frac{4}{8}[/tex]
[tex]x=\frac{1}{2}[/tex]
So, The vertical asymptote is[tex]\frac{1}{2}[/tex]
Hence the vertical asymptote for the reciprocal of y=8x-4 is [tex]\frac{1}{2}[/tex]
The names of 5 boys and 5 girls are in a hat. What is the probability of first drawing a girl’s name and then a boy’s name from the hat?
Answer:
9/20
Step-by-step explanation:
The probability of drawing a girl's name is 0.5, since there are 5 girls in 10 kids here. If that girl's name is not replaced, then the probability of drawing a boy's name is 5/9, since there are still such names but the total number of names is now 9.
Thus, the probability of this joint event is (0.5)(9/10) = 4.5/10 = 9/20
Answer:
so drawing a girls name from the hat would be 5/10 since 5 girls are there out of 10 students in total. After, you pick the girls name the total number of student names would become 9 and since there are 5 guys, you get a 5/9 probability

What is the radius of the circle if it has a circumference of 153.86153.86153, point, 86 units.
Answer:
24.49 units
Step-by-step explanation:
The circumference of the circle is 153.86 units.
The circumference of a circle is given as:
C = 2 * pi * r
where r = radius of the circle
Therefore:
r = C / (2 * pi)
=> r = 153.86 / (2* pi) = 24.49 units
The radius of the circle is 24.49 units.
Answer:
24.49

Four different positive integers have a product of 110.
What is the sum of the four integers?
Answer:32.09
Step-by-step explanation:
Answer:
19
Step-by-step explanation:
To Find Out What are the four Positive Integers, Let's Prime Factorize 110:
110 = 1 × 2 × 5× 11
This means these are the four positive integers by multiplying which results in 110.
Now, The sum of these integers:
=> 1+2+5+11
=> 19
Simply the expression [tex]\frac{x-7}{3} - \frac{5-x}{2}[/tex]
Answer: [tex]\frac{5x-29}{6}[/tex]
Step-by-step explanation:
To simplify the equation, we can just subtract the 2 fractions. First, we need to make sure they have a common denominator.
[tex]\frac{2(x-7)}{6} -\frac{3(5-x)}{6}[/tex]
Now that the fractions have the same denominator, we can distribute the numerator and subtract.
[tex]\frac{2x-14}{6} -\frac{15-3x}{6} =\frac{2x-14-15+3x}{6} =\frac{5x-29}{6}[/tex]
The interior angles of a triangle are 42°,56° and 2x°. Find the value of x.
Answer:
41 degrees
Step-by-step explanation:
Since the sum of the interior angles of a triangle will always be 180 degrees:
42+56+2x=180
2x=82
x=41
Hope this helps!
Answer:
X=41°[tex]solution \\ 42 + 56 + 2x = 180(sum \: of \: angle \: in \: triangle) \\ or \: 98 + 2x = 180 \\ or \: 2x = 180 - 98 \\ or \: 2x = 82 \\ or \: x = \frac{82}{2} \\ x = 41[/tex]

x/5 + 1 = 7
Steps:
Step 1: Simplify both sides of the equation.
1 /5x+1=7
Step 2: Subtract 1 from both sides.
1/5x+1−1=7−1
1/5x=6
Step 3: Multiply both sides by 5.
5*(1/5x)=(5)*(6)
Description:
Since we are solving for x first steps is to Simplify both sides of the equation. Then subtract 1 from both sides. After that multiply both sides by 5 and you will get your answer. The correct answer for this question is x=30.
Answer: x=30
Please mark brainliest
Hope this helps.
The value of x from the given equation is 30.
The given equation is x/5 +1=7.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, x/5 +1=7
Transpose 1 to other side of the equation, we get
x/5 =7-1
x/5 = 6
Transpose 5 to other side of the equation, we get
x = 6×5
x = 30
Therefore, the value of x from the given equation is 30.

Since slope is calculated using the formula m = StartFraction v 2 minus v 1 Over x 2 minus x 1 EndFraction, the slope of both lines is equivalent to ________. It is given that the lines are parallel, and we calculated that the slopes are the same. Therefore, parallel lines have the same slopes.
Answer:
The product of these slopes is [(d-b)/(c-a)] × [(c-a)/(-d+b)] = -1
Proved: This product shows that the slopes are negative reciprocals

The complete question as seen on brainly ( question ID = 13270010):
Determine the missing information in the paragraph proof.
Given: Line PQ is rotated 90° counterclockwise to form line P’Q’. The lines are perpendicular. Line PQ contains the points (a, b) and (c, d). Line P’Q’ contains the points (–b, a) and (–d, c).
Prove: The slopes of perpendicular lines are negative reciprocals.
The slopes of lines PQ and P’Q’ can be determined using the formula m = StartFraction v 2 minus v 1 Over x 2 minus x 1 EndFraction
The product of these slopes is ________. This product shows that the slopes are negative reciprocals. It is given that the lines are perpendicular and we have shown that the slopes of the lines are negative reciprocals.
Step-by-step explanation:
Line PQ contains the points (a, b) and (c, d)
Line P’Q’ contains the points (–b, a) and (–d, c)
The two lines are said to be perpendicular.
For two lines are said to be perpendicular, the product of the slope of the two lines must be equal to -1.
Let's determine if it's true for this two lines.
Find attached the the diagram and explanations.
The product of these slopes is [(d-b)/(c-a)] × [(c-a)/(-d+b)] = -1
This product shows that the slopes are negative reciprocals

What is the decimal multiplier to increase by 99%?
Answer:To work out the multiplier, first add or subtract the percentage from 100, then convert to a decimal. Example: we want to add 20% to £110. To work out the multiplier, add 20 to 100, to get 120, and then change it to a decimal (divide by 100) to get 1.2.
Step-by-step explanation:
The decimal multiplier of a number to increase by 99% will be 1.99.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Let's consider the number x.
To increase it by 20% we need to find 20% of it so 0.20x
Now, add this 20% to x so that it will increase by 20% as,
0.20x + x = 1.20x
Thus,to increase the number by 20% we need to multiply 1.20
Similarly to increase a number by 99% we need to multiply with 1.99.
Hence "The decimal multiplier of a number to increase by 99% will be 1.99".

Answer:
Choice 1
Step-by-step explanation:
1.
The function is in fact decreasing non linearly from x=4 to x=11, which becomes apparent if you look at the graph from 4 to 11.
2.
Between x=1 and x=4, the graph is increasing, but not linearly so.
3.
Between x=-7 and x=-4, the graph is nonlinear, but it is increasing, not decreasing.
4.
Between x=-4 and x=1, the graph is linear, but it is neither increasing nor decreasing, rather staying constant.
Therefore, the correct answer is choice 1.

Mary is paid 7.5% commission on all of her sales. She had sales of $2300 for the month of December. How much commission did Mary make?
Answer: $172.50
Step-by-step explanation:
$2300 x 0.075 = $172.50
You can double check quickly because you know 10% of 2300 is $230, so 5% is $115. The answer is halfway between the 5% and 10% numbers, so you know it is reasonable.
