Step-by-step explanation: Two competing companies are having sales on laptops. Laptop #AX330M has a retail price of $2,100. The Buy Less is advertising #AX330M for 15% off, while Sell More has stated they will match any competitor’s advertised special and take an additional 10% off of the competitor’s advertised price. How much money is saved by purchasing the laptop from Sell More instead of Buy Less?
15. PLZ HELP For each part below, use the figure to fill in the blank. If necessary, you may learn what the markings on a figure indicate. (a) Find Q (b)Find m < M.
Answer:
a. m<Q = 75°
b. m<M = 60°
Step-by-step explanation:
a. The triangle has two equal sides, therefore it is an isosceles triangle. Thus, its base angles would be equal also. m<Q = m<S
Therefore:
m<Q = ½(180 - 30)
m<Q = 75°
b. All sides of the triangle are equal. Therefore, it is an equilateral triangle with equal angles measuring 60° each.
m<M = 60°

EDCITE !!! HELP PLEASE !
Answer:
34
Step-by-step explanation:
The angles of a triangle add to 180
56+ F + 90 = 180 ( the box means 90 degrees)
Combine like terms
146+F = 180
Subtract 146 from each side
F = 180-146
F = 34
a total of 10000 was invested in two business ventures A and B .at the of the first year A and B yielded returns of 6% and 23÷4 respective on the original investment how was the original amount allocated if the total amount earned was 588.75?
Answer:
(1)
compound amount = 802.5 $
invest earned = 52.5 $
Step-by-step explanation:
total amount = 10000 $
let amount x invested in ventures A and remaining (1000-x) on ventures B
now,
6x/100 +23/400(1000-x ) = 588.75
{24x+23(1000-x)}/400 =588.75
x=235500-230000
x=5500
Amount invested on A = 5500$
Amount invested on B = 4500$
(2)
principle=750$
time= 1 year
effective invest rate = 7%
a) compound amount = p(1+(r/w)^t
=750{1+(7/100)}^1
=802.5$
b) invest earned = 802.5-700 = 52.5$
Please help me!! i have no clue how to do this unit :(
Answer:
the area is 27
Step-by-step explanation:
Answer:
the base of this shape is 6
lets break it up into a rectangle and a triangle
the rectangle is 6(base) time 3(height)=18
the triangle is 6(base) times 3(height) divided by two = 9
18 plus 9 = 27
Find y.
A. 42–√
B. 4
C. 22–√
D. 83√3
Answer:
B
Step-by-step explanation:
You always have to use the Big Three trig functions (those that are on your calculator when answering this kind of question involving right angle triangles).
y is the adjacent side of the triangle. It is the side (other than the hypotenuse -- which is the longest side of the right triangle) that makes up the cosine.
Cos(45) = y / 4 sqrt(2)
Cos(45) = sqrt(2)/2
Multiply both sides by 4 sqrt(2)
4*sqrt(2) * cos(45) = y
4*sqrt(2) * sqrt(2)/2 = y
2*2 = y
y = 4
I can't tell you where all the other choices are coming from.

what are the principle and symmetric solutions to the equation 2cos(x)=-1
Answer:
Assuming that x is in degrees (you could generalize this to any unit)
For an equation like:
sin(a*x) = K
The principle solutions are the values of x in the range:
0° ≤ x < 360°
And the symmetric ones are the solutions:
xₙ = x + n*360°
where n is an integer.
Ok, first let's solve:
2*cos(x) = -1
isolating the cosine part, we get:
cos(x) = -1/2
Now we can use the inverse cosine function, Acos(x)
If we apply this function to both sides, we get:
Acos (cos(x)) = Acos(-1/2)
x = Acos(-1/2) = 120°
x = 120° is the princpiple solution.
And the symmetric solutions are:
xₙ = 120° + n*360°
So for example:
x₁ = 120° + 1*360° = 480°
x₃ = 120° + 3*360° = 1200°
etc...
Which statements are correct? Check all that apply.

Classify the angle pairs
Answer:
Alternate exterior
Step-by-step explanation:
Angles 2 and 7 are on exterior sides of the transversal and also are opposite to one another. They are classified as alternate exterior.
Answer:
alternate exterior angles
Step-by-step explanation:
2 and 7 are on opposite sides of the transversal so they are called alternate
They are on the outside of the parallel lines so the are called exterior

stay safe healthy and happy..Find the measurement of the numbered angles
Answer:
m<1 = 60
m<2 = 30
m<3 = 80
Step-by-step explanation:
1. Solve for angle (1)
The sum of angles in any triangle is (180) degrees. As one can see, there is a (30) degree angle in this triangle, and a (90) degree angle. Bear in mind that the box around an angle indicates that it is a (90) degree angle. One can form an equation and solve for the unknown angle using this given information;
(30) + (m<1) + (90) = 180
Simplify,
120 + m<1 = 180
Inverse operations,
m<1 = 60
2. Solve for angle (2)
The vertical angles theorem states that when two lines intersect, the angles opposite each other are congruent. One can apply this theorem here by stating the following,
m<2 = 30
Thus one gets their answer, the measure of angle (2) must be (30) degrees by the vertical angles theorem.
3. Solve for angle (3)
As states above, the sum of angles in a triangle is (180) degrees. Since one has found the measure of angle (2), one can form an equation and solve for the measure of angle (3) using the given information, combined with the information found.
(m<2) + (70) + (m<3) = 180
Susbtitute,
30 + 70 + (m<3) = 180
Simplify,
100 + m<3 = 180
Invers eoperations,
m<3 = 80
x^ 3 + 3 x ^ 2 - 9 x - 27 draw the graph of the first derivative and the second derivative on the same set
Answer:
The graph is in the second attached image.
Step-by-step explanation:
In the first attached image, you have three equation graphed, the first is in red color, it's the original equation:
x^3 + 3x^2 - 9x - 27I graphed this to obtain a clear relation between the equation and its derivatives, the second graphed equation is in blue color and it's the first derivative:
First derivative = 3x^2 + 6x - 9 (It's a parabola)And at last, we have in green color the second derivative:
Second derivative = 6x + 6 (It's a line)As you can see, you only need the first and the second derivatives in the exercise, by this reason, in the second attached image you have the graph as you need to show in this exercise.

Rectangle ABCD is transformed to A’B’C’D’ by a dilation. What is the scale factor used for the dilation?
Answer:
Scale factor = 3
Step-by-step explanation:
Scale factor used for the dilation = the ratio of the corresponding side length of the new figure to the side length of the original figure
Scale factor = B'C'/BC
B'C' = 9 units
BC = 3 units
Scale factor = 9/3 = 3
