Andrea conducts a science experiment and observes that the height of a plant depends on the amount of sunlight it receives. The plant’s height is 37 centimeters, and it grows at a rate of 0.004 centimeter per hour of sunlight. If the number of hours of sunlight is represented by the variable s, which function can represent the height of the plant?
s(h) = 0.004h – 37
f(h) = 37h + 0.004
f(s) = 0.004s + 37
Answers
Answer:
f(h) = 0.004s + 37
Step-by-step explanation:
The correct representation of the height of the plant is;
f(h) = 0.004s + 37
Given parameters;
Height of plant = 37cm
Rate of growth = 0.004cm/hr
Number of hours of sunlight = s
To solve this problem, the height of the plant is directly dependent on the amount of sunlight;
f(h) signifies that height is a function
The height of the plant is 37cm;
f(h) = 37
The plant grows at a rate of 0.004cm/hr; number of hours of sunlight is s;
0.004s
Therefore;
f(h) = 37 + 0.004s
Answer:
f(s)=0.004s+37

Explanation:
To find the slope, all you need are two points.
Pick any two columns to form the two points. Once you have your two points, use the slope formula
I'll use the first two columns
m = (y2-y1)/(x2-x1)
m = (12.2-13)/(4-0)
m = -0.8/4
m = -0.2 is the slope
The y intercept is b = 13 since x = 0 leads to y = 13 (column 1)
With m = -0.2 and b = 13, we go from y = mx+b to y = -0.2x+13

Suppose you had two circular objects. Let the first circular object have a diameter of 26 cm and let second circular object have a diameter that is half as long as the diameter of the first. What would the circumference be for the second item in centimeters?
Answers
Answer:
40.82cm
Step-by-step explanation:
half of 26 is 13
the second's circle diameter is 13
the formula for circumference is C = 2πr
where r is the radius and π is 3.14
diameter =2r
13 = 2r
r = 6.5
2 x 6.5 x 3.14 = 40.82
40.82 cm

Movers Company manufactures sneakers. The production of their new sneaker for the coming three months is budgeted as follows: August 30,000 September 50,000 October 35,000 Each sneaker requires 2 hours of direct labor time. Direct labor wages average $15 per hour. Monthly overhead averages $10 per direct labor hour plus fixed overhead of $4,500. What is the direct labor cost budgeted for September?
Answers
Answer:
Direct labor cost= $1,500,000
Step-by-step explanation:
Giving the following information:
Production:
September 50,000
Each sneaker requires 2 hours of direct labor time.
Direct labor wages average $15 per hour.
First, we need to calculate the number of direct labor hours required:
Direct labor hours= 50,000*2= 100,000 hours
Now, the direct labor cost:
Direct labor cost= 100,000*15= $1,500,000

Step 2: Solve for x
Add 11 to both sides: 8 = xRewrite x = 8Step 3: Check
Plug in x to verify it's a solution.
-3 = 8 - 11
-3 = -3
Answer:
X = 8
Step-by-step explanation:
8-11= -3. I think the easiest way to solve this if you are new to negative numbers is to use a number line.

-14 = -4(9x - 1)
Answers
Answer:
x = 0.5
Step-by-step explanation:
First, distribute -4 to the parentheses:
-14 = -4(9x - 1)
-14 = -36x + 4
Subtract 4 from both sides:
-18 = -36x
Divide each side by -36
0.5 = x
x = 0.5
➠ -14 = -4(9x - 1)
Multiplying by -1 on both sides,
we ge[tex]t[/tex]
➠ 14 = 4(9x - 1)
➠ 14 = (4 × 9x) - (4 × 1)
➠ 14 = 36x - 4
➠ 36x = 14 + 4
➠ 36x = 18
➠ x = 18/36
➠ x = 1/2
➠ x = 0.5
