Answer:
there are 8 numbers, all are negetive and they are multiplied with each-other
we know, (-negative)(-nagative) = positive number
so even quantity of negative numbers multiplied with each-other makes a positive number.
so the sign of the product is +
Step-by-step explanation:
A salesperson works 40 hours per week at a job where has two options for being paid. Option A is an hourly wage of 23$. Option B is a commission rate of 10% on weekly sales. How much does need to sell this week to earn the same amount with the two options
Answer:
$9200
Step-by-step explanation:
Since he works 40 hours a week and would make $23 for every hour with option A, we just multiply 40 by 23
40 x 23 = 920
This means 10% of the sales will need to equal to 920
Let x = sales
We multiply x by 0.1 to get 920
0.1x = 920
Divide both sides by 0.1
0.1x/0.1 = 920/0.1
x = 9200
Which statements about the graphs of y = 1/2sin x and y = 1/2sin(x - π /2) are true?
Select all that apply.
A) The graph of y = sin(x - π/2) is shifted units π /2 units left from the graph of y=1/2sin x.
B) The graph of y = 1/2sin(x - π/2) is shifted units π /2 right from the graph of
y = 1/2 sin x.
C)The period of y=1/2sin(x - π/2) is π/2, and the period of y = 1/2sin x is 2 π.
D)The amplitude of y = 1/2sin(x - π/2) is half the amplitude of y = 1/2 sin x.
E)The amplitude of y=1/2 sin(x - π/2) is the same as the amplitude of y = 1/2 sin x.
The correct answer is option B) The graph of y = 1/2sin(x - π/2) is shifted units π /2 right from the graph of y = 1/2 sin x.
How do you describe a graph?
For most graphs, give a brief description including the title and axis labels, and mention trends not already described in the text. For simple charts, state the actual data points. For more complex charts, an ideal description would include the data in a table or list.

let f(x)=-2x-7 and g(x)=-4x+3 find (f°g)(-5)
Answer:
-53
Step-by-step explanation:
f°g = f(g(x)) Remember this because this notation is less confusing for you.
Step 1. Plug g(x) in all values of x in the function f(x).
f(g(x)) = -2(-4x+3) -7
Step 2. Distribute the -2
-2(-4x+3) = 8x -6
f(g(x)) = 8x-6-7
Step 3. Simplify by subtracting -6 - 7
f(g(x)) = 8x-13
Step 4. Plug in -5 for x
8(-5) - 13 = -40 - 13 = -53
What happens to the x and y coordinates in a 90-degree counterclockwise rotation?
Answer: hope this helps i didnt see any A, B, C, D etc options to choose from
each point of the given figure has to be changed from (x, y) to (-y, x)
Step-by-step explanation:
When we rotate a figure of 90 degrees counterclockwise, each point of the given figure has to be changed from (x, y) to (-y, x) and graph the rotated figure.
Example 1 :
Let F (-4, -2), G (-2, -2) and H (-3, 1) be the three vertices of a triangle. If this triangle is rotated 90° counterclockwise, find the vertices of the rotated figure and graph.
Solution :
Step 1 :
Here, triangle is rotated 90° counterclockwise. So the rule that we have to apply here is
(x, y) -------> (-y, x)
Step 2 :
Based on the rule given in step 1, we have to find the vertices of the rotated figure.
Step 3 :
(x , y) -----> (-y , x)
F(-4 , -2) -------> F'(2, -4)
G(-2, -2) -------> G'(2, -2)
H (-3, 1) -------> H'(-1, -3)
Step 4 :
Vertices of the rotated figure are
F'(2, -4), G'(2, -2) and H'(-1, -3)

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2.4 h, and Car B traveled the distance in 4 h. Car A traveled 22 mph faster than Car B.
How fast did Car A travel?
(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)
Enter your answer in the box.
Answer:
We let x the distance traveled by Car A and y the distance traveled by car B. The speed of car A can be represented as x/2.4 and for Car B is y/4. From the statement given, we can write an equation relating the speed of both cars.
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
Solving for x, we obtain:
x= 132 meters traveled by both cars
Therefore, Car A has a speed of 55 mph.
Step-by-step explanation:

What is the measure of angle A′OB′?
Answer:79°
Step-by-step explanation:
If 5 bats and 4 balls weigh 58 kg, and 4 bats and 5 balls weigh 50 kg, then how much does a bat weigh?
The bat weighs 10kg.
Two equations can be gotten from the question:
5a + 4b = 58 equation 1
4a + 5b = 50 equation 2
Where:
a = weight of bats
b = weight of balls
The two equations are simultaneous equations and would be solved using the elimination method.
In order to determine the weight of balls, take the following steps:
Multiply equation 1 by 4 and equation 2 by 5
20a + 16b = 232 equation 3
20a + 25b = 250 equation 4
Subtract equation 3 from 4
18 = 9b
Divide both sides of the equation by 9
b = 2kg
In order to determine the weight of bats, take the following steps:
Replace for b in equation 1
5a + 4(2) = 58
5a + 8 = 58
5a = 58 - 8
5a = 50
Divide both sides of the equation by 5
a = 10kg

3. In the diagram below AB' is the image of AB after a reflection in AC. If mBAC4x7 and mBAB ' 64 , then which of the following is the value of x?
(1) 6.25 (3) 14.25 (2) 12.5 (4) 18.75
When a line or shape or point is reflected, it must be reflected over a line.
The value of x is (b) 14.25
Reflection is a rigid transformation;
This means that:
[tex]\mathbf{\angle AC = \angle AB}[/tex]
So, we have
[tex]\mathbf{4x + 7 = 64}[/tex]
Subtract 7 from both sides
[tex]\mathbf{4x = 57}[/tex]
Divide both sides by 4
[tex]\mathbf{x = 14.25}[/tex]
Hence, the value of x is (b) 14.25
