Answer: To find the surface area of this object, we need to find the area of each of its faces and add them together.
The object has two faces that are 6 cm by 5 cm, which gives an area of:
6 cm x 5 cm = 30 sq. cm
The object also has two faces that are 5 cm by 3 cm, which gives an area of:
5 cm x 3 cm = 15 sq. cm
Finally, the object has two faces that are 3 cm by 3 cm, which gives an area of:
3 cm x 3 cm = 9 sq. cm
Adding up the areas of all six faces, we get:
30 sq. cm + 30 sq. cm + 15 sq. cm + 15 sq. cm + 9 sq. cm + 9 sq. cm = 108 sq. cm
Therefore, the surface area of the object is 108 square centimeters.

help me it's the 23 and the 24 please.
Answer:
On the graph, the point balances for the three friends on the 23rd week are:
- Friend A: 60 points
- Friend B: 80 points
- Friend C: 40 points
On the 24th week, the point balances are:
- Friend A: 80 points
- Friend B: 100 points
- Friend C: 60 points
It looks like all three friends are earning points and increasing their balances over time. Friend B seems to be earning points at a faster rate than the other two friends, as their balance is consistently higher. Friend C has the lowest balance, but is still earning points and increasing their balance.

Vol_total
= 7800 yd^3
Step-by-step explanation:
The bottom part of your shape is a box, basically (rectangular prism) and the volume is:
V=
length×width×height
Those numbers are all given. Because it is a box shape, it doesn't matter which number is which.
V = 22 × 15 × 16
= 5280 yd^3
Now the "roof" part on top is a little bit different. It is a triangular prism. So the side that needs to be the Base of the prism is the front (or back) triangle.
The volume is:
V
= BaseArea×height
= Area_triangle× ht
= 1/2 bh × height
= 1/2•21•16 × 15
The key to understanding is knowing the triangle must be the base. And the roof line running front to back will be the height. And also understanding the difference between the height of just a triangle (21) and the height of the prism(15). They are different.
Vol_roof = 2520
Then add them together.
Vol_total
= 5280 + 2520
= 7800 yards cubed
E) Let y = g(x) be the particular solution to the differential equation dy/dx= 3sin(pix)/2y with initial condition
g(1/2)=3. Then g(x)= sqare root of a+bcos(pix) where a and b areconstants. Find a
Answer:
9
Step-by-step explanation:
You want the value of the constant 'a' in the solution y=√(a+b·cos(πx)) to the differential equation y'=3sin(πx)/(2y) with initial condition y(1/2) = 3.
Initial conditionSubstitute the initial condition into the equation for y:
y = 3 . . . . when x = 1/2
y = √(a +b·cos(πx))
3 = √(a +b·cos(π/2)) = √a
3² = a = 9
The value of a is 9.
__
Additional comment
The value of 'b' is -3/π.
It can be found by putting the equation for y in the original differential equation, and solving for b.

After translatiοn, the cοrrect answer is B' (x+2, y+6).
The cοοrdinate after reflectiοn is (3,2).
The translatiοn rule that describes the result οf cοmpοsitiοn is (x, y) →(x-1, y-6).
What are transfοrmatiοns?Transfοrmatiοns in a triangle refer tο changes that can be made tο the shape, size, pοsitiοn, οr οrientatiοn οf the triangle οn a cοοrdinate plane. The three main types οf transfοrmatiοns that can be applied tο a triangle are:
Translatiοn: This transfοrmatiοn invοlves mοving the entire triangle tο a new pοsitiοn οn the cοοrdinate plane withοut changing its size οr shape.
Rοtatiοn: This transfοrmatiοn invοlves rοtating the entire triangle arοund a fixed pοint οn the cοοrdinate plane. The fixed pοint is called the center οf rοtatiοn, and the angle οf rοtatiοn determines the amοunt οf turn.
Scaling: This transfοrmatiοn invοlves changing the size οf the triangle by multiplying the x and y cοοrdinates οf each vertex by a fixed factοr.
1) Applying the translatiοn οf (x-2, y+3) tο pοint B(4,3) wοuld result in: B' = (4 + (x-2), 3 + (y+3)) = (x+2, y+6)
Therefοre, the cοrrect answer is B' (x+2, y+6)
2) Reflecting pοint G(3,-2) acrοss the x-axis results in the y-cοοrdinate being negated, and the x-cοοrdinate remains the same. Therefοre, the cοοrdinates οf the reflected pοint wοuld be G(3, 2).
The cοrrect answer is (3,2).
3) Tο determine the cοmpοsitiοn οf (x, y) → (x+4, y⁻¹) and (x, y) →(x-5, y⁻⁵), we need tο apply them in οrder. Firstly, (x, y) → (x+4, y-1) is applied tο pοint (x,y), which results in:(x, y)→ (x+4, y-1)
Next, (x, y) → (x-5, y-5) is applied tο the result frοm the previοus transfοrmatiοn (x+4, y-1), which results in:(x+4, y-1)→(x-1, y-6)
Therefore, the correct answer is (x, y) →(x-1, y-6).

Work out the equation of the straight line that passes through (5, 4) and (8, 19). Give your answer in the form y = mx + c, where m and c are integers or fractions in their simplest forms.
Answer:
y = 5x - 21
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 4 ) and (x₂, y₂ ) = (8, 19 )
m = [tex]\frac{19-4}{8-5}[/tex] = [tex]\frac{15}{3}[/tex] = 5 , then
y = 5x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (5, 4 ) , then
4 = 5(5) + c = 25 + c ( subtract 25 from both sides )
- 21 = c
y = 5x - 21 ← equation of line

3x0 for every term 0 is = to one in a exponent value so it become 3x1
3x1 = 3
So the answer is 3..
Step-by-step explanation:
In the 3x+1 problem, no matter what number you start with, you will always eventually reach 1. The problemproblm has been shown to be a computationally unsolvable problem.
Rhonda kept track of the cats at a shelter where she volunteers. She measured how many times per day each cat ate, and she also ranked their activity level on a scale from 1 to 10 each day. She found the line of best fit for the data has the equation y=0. 23x+4. 1, where x represents the activity level and y represents the number of meals eaten.
If a cat had an activity level of about 9, then it's likely to have eaten about _[blank]_ meals.
Enter the value that correctly fills in the blank.
Round to the nearest whole number, if necessary, like this: 42
A cat would probably have consumed about 6 meals if its activity level had been around 9.
A linear equation is a relation between two variables in which one is dependent on the other in such a manner that changing one of the variables causes the change in another variable "linearly".
The above statement can be represented mathematically as,
y=mx+b
where m represents the rate of the change and c is the initial value of the equation.
Let x stand for activity level and y for the number of meals consumed. Therefore:
y = 0.23x + 4.1
For an activity level of 9, we will put x as 9:
y = 0.23(9) + 4.1 = 6.17
Thereby, we can say that If a cat had an activity level of about 9, then it's likely to have eaten about 6 meals.

The farmer now has 1377 sheep. If the farmer loses 32.5% of his 2400 sheep due to the drought, then he will have: 2400 * (1 - 0.325) = 1620 sheep left after the drought.
The farmer had 2400 sheep, but he lost 32.5% of them due to drought. Using the formula for finding percentages, we can calculate that 32.5% of 2400 is 780. So, the farmer had 2400 - 780 = 1620 sheep left after the drought. However, he then lost 15% of those remaining sheep due to sickness. Using the same formula, we can calculate that 15% of 1620 is 243. Therefore, the farmer had 1620 - 243 = 1377 sheep left after the sickness. So, the final number of sheep the farmer has now is 1377.

The answer of the given question based on finding the area of the shaded sectors the answer is approximately 18.8 + 4.2 = 23.0 square units.
What is Angle?An angle is geometric figure formed by the two rays or lines that share common endpoint, called vertex. The rays or lines are often referred to as arms or sides of angle
We need to know the central angles of each sector. We can find these angles by using the formula:
angle = (arc length / radius) * (180/π)
where π is pi, approximately equal to 3.14.
Therefore, we can use trigonometry to find angle EOB:
sin(EOB) = EB/OA
sin(EOB) = 10.4/8
EOB = sin^-1(10.4/8)
EOB ≈ 56.7° degrees
Since angle EOA is a right angle, we know that angle AOB is 90° degrees, so angle AOE is 90 - EOB = 33.3° degrees.
Now, we can find the area of each sector using the formula:
area = (angle/360) * π * r²
Area of shaded sector ADE:
angle AOE = 33.3° degrees
radius = OA = 8
area = (33.3/360) * π * 8²
area ≈ 18.8 square units
Area of shaded sector EBC:
angle EOB = 56.7° degrees
radius = EB/2 = 5.2
area = (56.7/360) * π * 5.2²
area ≈ 4.2 square units
Therefore, the total area of the shaded sectors is approximately 18.8 + 4.2 = 23.0 square units.
