The length of the side labelled, AB as represented in the image attached to the task content is; 5.63.
What is the length of the side AB given the angle B and side BC as in the image attached to the task content?It follows from the task content that the length of the side AB is to be determined from the right triangle given in the task content.
Since the angle given is; B whose measure is; 62°. It consequently follows that the trigonometric ratio to be used is cosine;
Cos 62 = adjacent/ hypothenuse
Cos 62° = AB/12
AB = 12 Cos 62°
AB = 12 × 0.4695
AB = 5.63

14. A manufacturer of lighting fixtures has daily production costs of C = 120 − 5x + 0.25x 2 , where C is the total cost (in dollars) and x is the number of units produced. How many fixtures should be produced each day to yield a minimum cost? What is that minimum cost?
Answer:
Value of x = 10
Minimum cost (C) = 45
Step-by-step explanation:
Given:
Equation:
120 - 5x + 0.25x²
Find:
Value of x
Minimum cost
Computation:
0.25x² - 5x + 120
x = -[b/2a]
x = -[(-5)/2(0.25)]
x = 10
Value of x = 10
Minimum cost (C) = 120 - 5x + 0.25x²
Minimum cost (C) = 120 - 5(10) + 0.25(10)²
Minimum cost (C) = 45
A sample of an unknown liquid has a volume of 24.0 mL and a mass of 6 g. What is its density?
Answer:
Hey there!
Density = Mass/Volume
Mass= 6g
Volume=24 mL, which is 24 cm^3
Density= 6g/24 cm^3
Density=0.25 g/cm^3
Let me know if this helps :)
Answer:
0.25g/ml
Step-by-step explanation:
Mass=6g
Volume=24ml
Density=Mass/Volume

all real numbers greater than or equal to -2
all real numbers greater than or equal to -3
Answer:
Option (4)
Step-by-step explanation:
Domain:
Domain of function is defined by the x-values (Input values) on the graph.
Range:
Range of a function is defined by the y-values (output values) on the graph.
From the graph attached,
x-values are starting from (-3) to infinity.
Therefore, domain of the function will be all real numbers greater than equal to (-3).

Studio fee:$8 per hour
Vase:$10
Answer:
x = hours spent8x+10 = 464.5 hoursStep-by-step explanation:
We are asked for the number of hours spent at the studio, so it is reasonable to let the variable x stand for the number of hours.
The total cost is ...
vase cost + hourly cost = total cost
where hourly cost = (# of hours)(cost per hour)
10 + 8x = 46
8x = 36 . . . . . . subtract 10
x = 4.5 . . . . . . . divide by 8
4.5 hours were spent at the studio.

Hey guys since nobody ever helps me and my mom doesn’t I need help on this assiment thanks :)
Liz is using the distributive property to evaluate the expression 27 (36) by using friendlier numbers. Her work is shown below. Liz's Work 27(36) Step 1 27 (3 + 12) Step 2 27 (3) + 27 (12) Step 3 81 + 324 Step 4 405
Answer:
Step 1 should have been 27(6 + 30).
Step-by-step explanation:
Given that:
The evaluation of the expression 27(36) by using the distributive property as portrayed by Liz is as follows:
27 (36)
Step 1 = 27 (3+ 12)
Step 2 = 27(3) + 27(12)
step 3 = 81 + 324
Step 4 = 405
What was the first error that Liz made?
From the above first step, we will see that :
27(3+12) was given, which is wrong.
the right step that is supposed to be there is:
27(6 + 30).
so the calculation will be:
Step 1 = 27(6+30)
Step 2 = 27(6) + 27(30)
Step 3 = 162 + 810
Step 4 = 972
I need help graphing this
=======================================================
Explanation:
The given equation y = (-2/3)x+1 is in the form y = mx+b
m = -2/3 is our slope
b = 1 is the y intercept
The y intercept is where the line crosses the vertical y axis. Because b = 1, this location is (0,1). So that's one point we can use to graph this equation.
Another point can be found using the slope
Recall that slope = rise/run
Since slope = -2/3, this means rise/run = -2/3 leading to rise = -2 and run = 3. The "rise = -2" portion tells us to go down 2 and then "run = 3" portion means we go to the right 3 units.
The "down 2, right 3" motion has us go from (0,1) to (3,-1). So (3,-1) is another point we can use. We only need two points to graph a straight line.
The diagram below provides a visual summary. It shows plotting point A as the y intercept, and then you move to point B using the "down 2, right 3" movement rule.
The temperature was 8°F. It dropped so that the temperature was 0°F.
Answer:
It dropped 8 degrees so the answer must be -8

Which line has the greatest rate of change?
A. The line passing through (0, 2) and (4, 10)
B. The line passing through (0,5) and (2,8)
C. The line passing through (0,0) and (3,-4)
D. The line passing through (0,6) and (12,9)
Answer:
I thought it was the last one but I mean if it was wrong sorry
Greetings from Brasil....
The rate of change between 2 points is obtained through the expression:
m = ΔY/ΔXm = (Y₂ - Y₁)/(X₂ - X₁)a) (0, 2) and (4, 10) so, X₁ = 0; X₂ = 4; Y₁ = 2 and Y₂ = 10
m = ΔY/ΔX
m = (Y₂ - Y₁)/(X₂ - X₁)
m = (10 - 2)/(4 - 0)
m = 8/4 = 2
b) (0,5) and (2,8) so, X₁ = 0; X₂ = 2; Y₁ = 5 and Y₂ = 8
m = ΔY/ΔX
m = (Y₂ - Y₁)/(X₂ - X₁)
m = (8 - 5)/(2 - 0)
m = 3/2
c) (0,0) and (3,-4) so, X₁ = 0; X₂ = 3; Y₁ = 0 and Y₂ = - 4
m = ΔY/ΔX
m = (Y₂ - Y₁)/(X₂ - X₁)
m = (- 4 - 0)/(3 - 0)
m = -4/3
d) (0,6) and (12,9) so, X₁ = 0; X₂ = 12; Y₁ = 6 and Y₂ = 9
m = ΔY/ΔX
m = (Y₂ - Y₁)/(X₂ - X₁)
m = (9 - 6)/(12 - 0)
m = 3/12 ⇔ m = 1/4
Among all the values above, the largest is 2, so points
(0; 2) and (4; 10)
daniel spent half of his paycheck on video games. to earn more money, he did chores at home and received $20. how much was his paycheck if he ended up with $56
Answer: His paycheck was $72.
Step-by-step explanation:
Let x = paycheck amount.
Given, Amount spent on video games = [tex]\dfrac x2[/tex]
Amount he has left of it = [tex]x-\dfrac x 2=\dfrac x 2[/tex]
Amount received = $20
Total amount amount he has left = [tex]\dfrac x 2 +20[/tex]
According to the question,
[tex]\dfrac x 2 +20 = 56\\\\\Rightarrow\ \dfrac x 2= 36\\\\\Rightarrow\ x= 2\times 36=72[/tex]
∴ His paycheck was $72.
Find the median of the following data.
46, 24,87, 64, 39, 50, 37, 48
Answer:
47
Step-by-step explanation:
46, 24,87, 64, 39, 50, 37, 48
First put the numbers in order from smallest to largest
24, 37, 39,46, 48,50,64,87
Then we notice that there are 8 numbers. The median is the middle
24, 37, 39,46 , 48,50,64,87
The middle is between 46 and 48
Take the average of these numbers
(46+48)/2 = 94/2 = 47
The median is 47
Answer:
49
Step-by-step explanation:
Fairly simple, line up the numbers in order from lowest to highest. Then find the middle two terms. Since we have 8 terms, we take the two in the center, 50 and 48 and add them together, then divide by two to get your median.
