The function p(h)=0.375h+3 represents the supply model to determine the millions of
available workers with the minimum hourly wage,h. Find the number of workers when the
minimum wage is $5.15 per hour. Round to the nearest hundredth place.
Answer:
4.93 million workers
Step-by-step explanation:
0.375*5.15+3 = 4.93125
The number of available workers is 4.93
The given expression:
[tex]p(h) = 0.375h + 3[/tex]
where;
h is the minimum hourly wage = $5.15
To find:
the number of workersThe number of available workers is calculated as follows:
[tex]p(5.15) = 0.375(5.15) + 3\\\\p(5.15) = 4.931\\\\p(5.15) \approx 4.93[/tex]
Thus, the number of available workers is 4.93

Recall that Rn denotes the right-endpoint approximation using n rectangles, Ln denotes the left-endpoint approximation using n rectangles. Calculate the approximation for each of the given function and interval below. (You may use calculator and keep the final numerical answer in decimals for this question) (a) (3 pts) R5, f(x) = x 2 + x on the interval [−1, 1]
Answer:
[tex]R_5=1.12[/tex]
Step-by-step explanation:
We want to calculate the right-endpoint approximation (the right Riemann sum) for the function:
[tex]f(x)=x^2+x[/tex]
On the interval [-1, 1] using five equal rectangles.
Find the width of each rectangle:
[tex]\displaystyle \Delta x=\frac{1-(-1)}{5}=\frac{2}{5}[/tex]
List the x-coordinates starting with -1 and ending with 1 with increments of 2/5:
-1, -3/5, -1/5, 1/5, 3/5, 1.
Since we are find the right-hand approximation, we use the five coordinates on the right.
Evaluate the function for each value. This is shown in the table below.
Each area of each rectangle is its area (the y-value) times its width, which is a constant 2/5. Hence, the approximation for the area under the curve of the function f(x) over the interval [-1, 1] using five equal rectangles is:
[tex]\displaystyle R_5=\frac{2}{5}\left(-0.24+-0.16+0.24+0.96+2)= 1.12[/tex]

Can someone help me with this part A: Members of a high school sports team are selling two popular items for a fundraiser:
candy bars and bags of chips. They earn $0.75 for every candy bar they sell and $0.50 for every
Dag of chips. The members want to earn at least $100 from all sales. The members of the sport
team estimate that they won't be able to sell more than 200 units in total.
Part A: Select all the inequalities that model the constraints for this situation, where x
represent the number of candy bars sold and y represent the number of bags of chips.
A. x 20
B. y20
C. x +y s 100

Step-by-step explanation:
Cx+y s 100
Answer:
All the inequalities that model the constraints for this situation:
(d) x + y < 200 ;
(e) 0.75 x + 0.50 y ≥ 100
Step-by-step explanation:
What is inequality ?A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
As, x represent the number of candy bars sold & y represent the number of bags of chips sold.
It is given that,
price for one candy bar = $0.75
also, price for one dag of chips = $0.50
So, price for 'x' candy bar = $0.75x
also, price for 'y' of chips = $0.50 y
Is is mentioned in question, the sale of candy bar and bag of chips shoud be atleast $100.
the First ineqaulity be,
0.75 x + 0.50 y ≥100
(which should the sales of candy baar and dag of chips be equal to 100 dollar or greater than 100 dollar)
Now, the second situation
Again, it is mentioned in the question is number of units (candy bar and dag of chips) should be not more than 200 units.
the second inequality be,
x+ y < 200
(which shows that number of candy bar and dag of chips should be less than 200 units.)
All the inequalities that model the constraints for this situation
(d) x + y < 200
(e) 0.75 x + 0.50 y ≥100

Answer:
A = 154°
B = 26°
C = 154°
Step-by-step explanation:
✔️A = 180° - 26° (angels on a straight line)
A = 154°
✔️<B and 26° are vertical angles. Therefore,
B = 26° (based in the vertical angles theorem, vertical angles are congruent to each other)
✔️C = A (based in the vertical angles theorem, vertical angles are congruent to each other)
Substitute
C = 154°

Answer:
1944 ft³ using the estimated height
Step-by-step explanation:
Ashleigh can use her estimate of the height, along with the other dimensions, in the volume formula to get an estimate of the volume.
V = LWH

If $2940 is invested at 3.2% compounded quarterly, how much is in the account after 8 years?
Answer:
The future value is $3793.776
Step-by-step explanation:
Given
[tex]PV = 2940[/tex] --- present value
[tex]r = 3.2\%[/tex] --- rate
[tex]t = 8[/tex] --- time
[tex]n = 4[/tex] --- quarterly
Required
Determine the future value
This is calculated using:
[tex]FV = PV(1 + \frac{r}{n})^{nt[/tex]
So, we have:
[tex]FV =2940 * (1 + \frac{3.2\%}{4})^{4*8[/tex]
[tex]FV =2940 * (1 + \frac{3.2}{400})^{32[/tex]
[tex]FV =2940 * (1 + 0.008)^{32[/tex]
[tex]FV =2940 * (1.008)^{32[/tex]
[tex]FV =2940 * 1.2904[/tex]
[tex]FV =3793.776[/tex]

A. Directions: Find the surface of the following. Round your answer to nearest
hundredths. (Use n = 3.14) Write your answer in your notebook.
1) cone with radius of 15 cm and slant height of 12 cm
2) cone with radius of 8 cm and slant height of 11 cm
3) sphere with radius of 3.2 cm
4) sphere with diameter of 6 cm
Answer:
1. S.A of a cone = 565.56 cm².
2. S.A of a cone = 276.496 cm².
3. S.A of a sphere = 128.696 cm².
4. S.A of a sphere = 113.112 cm².
Step-by-step explanation:
Given the following data;
1. Radius, r = 15cm
Slant height, l = 12cm
Mathematically, the surface area of a cone is given by the formula;
Surface area of a cone = πrl
Substituting into the formula, we have;
S.A of a cone = 3.142 * 15 * 12
S.A of a cone = 3.142 * 180
S.A of a cone = 565.56 cm²
2. Radius, r = 8cm
Slant height, l = 11cm
Surface area of a cone = πrl
S.A of a cone = 3.142 * 8 * 11
S.A of a cone = 3.142 * 88
S.A of a cone = 276.496 cm²
3. Radius, r = 3.2 cm
Mathematically, the surface area of a sphere is given by the formula;
Surface area of a sphere = 4πr²
Substituting into the formula, we have;
S.A of a sphere = 4 * 3.142 * 3.2²
S.A of a sphere = 4 * 3.142 * 10.24
S.A of a sphere = 40.96 * 3.142
S.A of a sphere = 128.696 cm²
4. Diameter, d = 6cm
Radius, r = diameter/2 = 6/2 = 3 cm
Surface area of a sphere = 4πr²
S.A of a sphere = 4 * 3.142 * 3²
S.A of a sphere = 4 * 3.142 * 9
S.A of a sphere = 36 * 3.142
S.A of a sphere = 113.112 cm²

Answer:
[tex]\bold{y=3x-11}[/tex]
Step-by-step explanation:
Begin with the equation [tex]y=mx+b[/tex]. Let's first find [tex]m[/tex].
For each time [tex]x[/tex] increases by 2 (the rows skip by 2), [tex]y[/tex] increases by 6. Since the relationship is linear, if [tex]x[/tex] were to increase by just 1 (half of 2), [tex]y[/tex] would increase by 3 (since we halve each component). Therefore, [tex]m=3[/tex].
To find [tex]b[/tex] (the y-intercept), we plug in the first value of [tex]x[/tex] we are given and notice the result. In this case, [tex]4 *3=12[/tex]. However, the first value of [tex]y[/tex] is 1, so we must subtract 11 so that the first term is 1. Hence, [tex]y=3x+11[/tex].
