[NEED HELP ASAP] How do I find the surface area of the shape in the picture?
Answers
When calculating the surface area of a 3D shape, it is important to remember to include the area of all the components that make up the shape.
How do I find the surface area of the shape in the picture?The surface area of the shape in the picture is approximately 300.4 cm².To calculate this, use the formula for the surface area of a triangular prism, which is SA = 2(bhl) + 2(bh + la).In this case, b = a = 4 cm, h = 12 cm, and l = s = 4.6 cm, so the calculation is SA = 2(4 x 12 x 4.6) + 2(4 x 4.6 + 4 x 12) = 300.4 cm².To calculate the surface area of the shape in the picture, you need to first calculate the area of the rectangle, triangle and circle.The rectangular portion has a height of 12 cm and a length of 4 cm, so the area is 48 cm^2.The triangle has a height of 12 cm and a base of 4 cm, so the area is 24 cm^2. The circle has a radius of 4.6 cm, so the area is 66.48 cm^2. Therefore, the total surface area of the shape is 138.48 cm^2. To calculate the surface area, you need to add the area of each of the components.For example, the area of the rectangle is 48 cm^2, the area of the triangle is 24 cm^2, and the area of the circle is 66.48 cm^2.The total surface area of the shape is then the sum of all these components, which is 138.48 cm^2.In this example, the rectangular portion, triangle and circle each had to be calculated separately in order to find the overall surface area.To learn more about the surface area of a of the prism refer to:

What is the formula for exponential growth and exponential decaying function?The formula for exponential growth is [tex]y = y_₀.e^{(kt)}.[/tex]
The formula for exponential decay is [tex]y = y_₀.e^{(-kt)}.[/tex]
Given, The population P(in thousands) of Austin Texas during a recent decade is approximated by [tex]y = 492(1.03)^t[/tex].
The model represents exponential growth as time can not be negative.
The annual percentage increase in the model [tex]y = 492(1.03)^t[/tex] is 3%
as 1.03×100% = 103%.
The time when the population was about 590000 since the beginning of a decade is,
[tex]590000 = 492(1.03)^t[/tex].
[tex](1.03)^t = 590000/492[/tex].
[tex](1.03)^t = 1199.1869[/tex].

y=2060-0.186x is the line of regression of a table of values comparing for front crash repair cost for rear crash repair cost for a certain models sedan use the equation to predict the full rear repair cost from a full front repair cost of $4594
Answers
Therefore the predicted full rear repair cost would be $1211.576 if y=2060-0.186x is the line of regression of a table of values comparing for front crash repair cost.
What is line of regression?When modeling the connection between a scalar answer and one or more explanatory variables in statistics, linear regression is a linear method. Simple linear regression is used when there is only one explanatory variable, while multiple linear regression is used when there are numerous variables.
What is scalar?Physical values known as scalars are unaffected by modifications to the vector space basis. Scalars frequently include units of measurement, such as "10 cm." Scalar quantities include things like mass, space, charge, volume, time, speed, and the overall size of physical vectors.
To predict the full rear repair cost from a full front repair cost of $4594, you would substitute 4594 for x in the equation y = 2060 - 0.186x and solve for y.
y = 2060 - 0.186(4594)
y = 2060 - 848.424
y = 1211.576
So the predicted full rear repair cost would be $1211.576

Answers
Answer:

Step-by-step explanation:
Key Word: 12 servings for every 5 people. if she makes it to hold 8 servings, what is enough plans she needs to feed 10 people?
formula: so 12 for 5 then 24 for 10.
solving problem:
12 people over 5 people = x over 10 people
since 5 times 2 equals 10 then 12 times is 24.. so we need 24 servings
we know from reading the question that each pan makes 8 servings.

Write an equation that represents the line. Use exact numbers
Answers
The equation of a line is y = 7/9x -3.5. using exact numbers from the graph.
What is the slope intercept of a line?
A straight line is produced by a linear function. Therefore, the slope has a constant value. If the slope was variable, a straight-line graph would not exist. When you know the slope of the line to be investigated and the given point is also the y-intercept, you can utilize the slope-intercept formula, y = mx + b. (0, b). The y value of the y-intercept point is denoted by the symbol b in the formula.
Given a line in the graph in that we can see that,
At x = 0, y is -3.5 and at y = 0, x is 4.5 thus,
coordinates of the given line are (0, -.35) and (4.5, 0)
Therefore the slope of the line (m) = (y₂-y₁)/ (x₂ -x₁)
The slope of the line = 3.5/4.5 = 7/9
therefore equation of the line in the slope-intercept form:
y = 7/9 x + c
Since this line passe from (0, -3.5)
hence, -3.5 = c
therefore, using exact numbers equation of the line is y = 7/9x -3.5.

Solve the equation x² - 4x+6=0 by completing the square.
BIUX² X₂ 15px help!!p
Answers
The solution of the equation x² - 4x + 6 = 0 using completing the square is x = 2 ± √(-2)
What is an equation?An equation is used to show the relationship between numbers and variables.
Polynomial can be classified based on degree of two as a quadratic equation.
Given the equation:
x² - 4x + 6 = 0
Solving using completing the square method:
subtract 6 from both sides:
x² - 4x = -6
add to both sides the square of half the coefficient of x:
x² - 4x + 4 = -6 + 4
(x - 2)² = -2
Taking square root of both sides:
x - 2 = ±√(-2)
x = 2 ± √(-2)
The solution is x = 2 ± √(-2)

Education order reads: 24 hours after bone marrow transfusion give Neupogen 10 mcg/kg/d IV. Supply on hand. Neupogan 300 mcg/ml. Patient’s weight 115 lbs. Give __ mL
Answers
Education order reads: 24 hours after bone marrow transfusion give Neupogen 10 mcg/kg/d IV. Supply on hand. Neupogan 300 mcg/ml. Patient’s weight 115 lbs. Give 1.74 mL
What is the Neupogen calculations about?To calculate the appropriate dosage of Neupogen to give to the patient, we need to convert the patient's weight from pounds to kilograms and then use the dosage provided in the order (10 mcg/kg/d IV).
First, we have to convert the patient's weight from pounds to kilograms:
115 pounds = 52.16 kg
Now we can use the dosage provided in the order (10 mcg/kg/d IV) to calculate the appropriate dosage for the patient:
10 mcg/kg/d IV
= 10 mcg/kg/day * 52.16 kg
= 521.6 mcg/day
Then, since the Neupogen is available in a solution of 300 mcg/ml, we can use the following formula to calculate the required volume of solution to give to the patient:
Volume = Dosage / Concentration
= 521.6 mcg / 300 mcg/ml
= 1.74 ml
So, the education order reads 24 hours after bone marrow transfusion, give 1.74 mL of Neupogen at a concentration of 300 mcg/mL IV.
