Greta currently works 45 hours per week and earns a weekly salary of $729. She
will soon be starting a new job where her salary will be increased by 10% and her
hours reduced by 10%.
How much more will she be earning per hour at her new job?
Answers
Answer:
Step-by-step explanation:
current rate = $729/(45 hours) = $16.20/hour
increased salary = 1.10×$729 = $801.90
decreased hours = 0.90×45 = 40.5
increased rate = $801.90/(40.5 hours) = $19.80/hour
increase in rate = $19.80/hour - $16.20/hour = $3.60/hour

find the maximum and minimum values of the function y=1/2 sin2x
Answers
Answer:
Maximum value equals 1/2
Minimum value equals -1/2
Step-by-step explanation:
The Sin Function when Graphed Shows a Range of [-1 , 1]
apply that on y=1/2 sin2x
y = 1/2 * 1 = 1
y = 1/2 * -1 = -1
so y = 1/2 , -1/2 .
Another Method using 1st derivativedy/dx = 2 * 1/2 * cos2x
put dy/dx=0
cos2x=0
x= 45, x=135
Apply x values on y=1/2 sin2x
y = 1/2 , -1/2 .

how many triangles can be constucted measuring 60°, 60°, and 40°
Answers
Answer:
None, the sum of those angles does not equal 180 degrees
Answer:
none of the traingle can be constructedThe answer of this question is none. The sum of these three angles is 160°. So, none of the triangles can be constructed with angles measuring 60°, 60° and 40°
60°+60°+40°=160°The sum of three angles is 160°
so, none of the traingle can be constructed with angles measuring 60°,60°and 40°.

Select the procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 5 cm, 9 cm, 12 cm, and 15 cm
Answers
Answer:
Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.
Step-by-step explanation:Pythagorean Theorem: According to this theorem the result obtained by squaring the value of the hypotenuse of a right angled triangle is equal to the sum of the squares of the values other two sides of the triangle.
Hypotenuse = h
Altitude = l
Base = b
l²+b²=h²
Here 6²=36
9²=81
12²=144
15²=225
From the above it is clear that
81+144=225
⇒9²+12²=15²
Therefore the hypotenuse of the triangle is 15 cm and other two sides of the triangle are 9 cm and 12 cm and one angle of the triangle is 90°.

Equation: y = 2x
Graph: see attachment
Step-by-step explanation:
Pieces of paper = x
Number of Valentines = y
The equation is a proportional equation and can be represented as y = kx
k is the constant of proportionality
k = y/x
Using (2, 4),
k = 4/2 = 2
To find the equation, substitute k = 2 into y = kx
Thus:
y = 2x

How can we get system B for system A?
And
Are the systems equivalent?
Answers
Answer: Subtract the equations in system A.
=============================================================
Explanation:
The first equation of each system is the same, so we'll try to transform the second equation of system A into the second equation of system B.
There are probably a number of ways to do this, but the quickest way that I can see is to subtract the equations of each system.
For system A, notice how the x terms line up and subtract to 5x-4x = 1x = x. In that same system, we have the y terms subtract to y minus (-7y) = y-(-7y) = y+7y = 8y
So far we have x and 8y as the results. So the left side is x+8y, which matches with the x+8y in the second equation of system B. So far so good.
Now we subtract the values on the right hand sides of each equation of system A. We get 3-8 which turns into -5, which also matches with the -5 in the second equation of system B.
Overall, subtracting the two equations of system A leads to x+8y = -5, which is the second equation of system B.
