A pencil case with a cylinder shape with diameter= 10 cm
and height = 12 cm .
What is the length of the longest pencil that can fit in the pencil case?
Answer:
length of the longest pencil that can fit must be less than 13cm
Step-by-step explanation:
To get the longest pencil that fit the case, we will use the pythagoras theorem;
diameter = 10cm
radius = 10/2
radius = 5cm
Height = 12cm
Get the length of the longest side
l² = r²+h²
l² = 5²+12²
l² = 25 + 144
l² = 169
l = √169
l = 13cm
Hence the length of the longest pencil that can fit must be less than 13cm
what is the equation, in point-slope form, of the ljne that is perpendicular to the given line and passes through the point (-4,-3)?
Answer:y+3=1/4(x+4)
Step-by-step explanation:
First find the slope of the line with the points -1,1 and 0,-3
1-(-3)/-1-0 = -4
perpendicular is negative reciprocal which is 1/4
now we have the slope, and a point so we can put it in point slope form
y+3=1/4(x+4)
point slope form is y-y1 = m(x-x1)
with x1,y1 being the point and m being the slope
Gary buys a skateboard for
$145. What's the total cost
including 6% sales tax?
Answer:
$8.6
Step-by-step explanation:
The total tax is 8 dollars and 60 cents
Answer:
$153.70
Step-by-step explanation:
Sales tax is applied to things that are sold by a retailer. So if it says 6% tax is levied on the item, that means the total cost will be the initial cost of skateboard ($145) + sales tax (6% of 145) = 145 + 8.7 = $153.70

Match the solution set given in inequality notation with the solution set given in interval motion x > 7.8
Answer:
(7.8, ∞)
Step-by-step explanation:
Given the inequality :
x > 7.8 ; the inequality can be explicitly interpreted as x greater than 8 ; this means that the inequality holds for all values of x above 7.8
The interval for which the inequality holds true is :
x > 7. 8 - - - > (7.8, ∞)
Which polynomial below could produce this graph?
Answer:
f(x) = (x + 20)(x - 24)(x + 10)(x + 12)
Step-by-step explanation:
This is an equation of degree 4 and as the beginning of the graph descends from negative x the polynomial will have a positive leading coefficient. The graph is roughly W shaped.
It also has zeroes at x = -20,-12 ,-10 and x = 24.
So it is the first option.

A line has a slope of -1/4 and passes through point
(-5/4, 1)
What is the equation of the line?
Answer:
y = -1/4 x+11/16
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -1/4x+b
Substitute the point in for x and y
1 = -1/4(-5/4) +b
1 = 5/16 +b
16/16 = 5/16 +b
Subtract 5/16 from each side
11/16 = b
y = -1/4 x+11/16
Answer:
y = - [tex]\frac{1}{4}[/tex] x + [tex]\frac{11}{16}[/tex]
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 )
Here m = - [tex]\frac{1}{4}[/tex] , then
y = - [tex]\frac{1}{4}[/tex] x + c ← is the partial equation
To find c substitute ( - [tex]\frac{5}{4}[/tex], 1 ) into the partial equation
1 = [tex]\frac{5}{16}[/tex] + c ⇒ c = 1 - [tex]\frac{5}{16}[/tex] = [tex]\frac{11}{16}[/tex]
y = - [tex]\frac{1}{4}[/tex] x + [tex]\frac{11}{16}[/tex]

Answer:
(b) 36 in²
Step-by-step explanation:
The right triangle at lower right has a vertical leg of 3 and a hypotenuse of 5. Then the horizontal leg is ...
√(5² -3²) = √16 = 4
Then the horizontal diagonal is 4+4 = 8. The vertical diagonal is 6+3 = 9. The area is half the product of the diagonals, so is ...
A = 1/2(d1)(d2) = 1/2(8 in)(9 in) = 36 in²
__
You could figure the areas of the triangles separately, but you would come to the same result. This formula is good for a rhombus or a kite (or a square, which is also a rhombus), because the diagonals are perpendicular to each other.
SOMEONE PLEASE HELP THIS IS DUE TOMROROW EZ WORK
PLEASE ANSWER THEM PROPERY FULL SENTENCES
Answer:
1.) At times, designing a good structure with a specific function may often be difficult. If the structure is not well-designed or strong enough for the function it will not properly work. So in order for the design to be well-built, both the structure and function must cooperate.
2.) Symmetry is a balanced arrangement on the opposite sides of a structure. In order for for a structure to be stable and properly work without complications, it most commonly needs to be symmetrical. This is a very important part of designing a structure.
3.) If the structure cannot withstand the function nor the possible forces that it may encounter. It is likely that it will break or even be completely destroyed.
4.) Shape, line, color, texture, movement, space. The designer may have taken into consideration whom the desk may be used by for the shape and space. Color, texture, and line may have been based on the environment (ex. A carpenter, student, computer desk) it would be in. Although the designer may not have an exact knowledge of where the desk would be, he still could consider what the desk could "possibly" be used for. Once again, the designer could take into consideration the user, for the movement of the desk. If the desk was to be moved around on wheels, or possibly could even fold. The designer must take into consideration EVERY detail.
6.) When people design something, often times you do not know how well that design is going to work without testing it with a prototype. Yes, prototypes are expensive. Yet, if they were to build something without testing their design, something may be wrong with it. So as a result, you will spend more money manufacturing something with a defect than testing it with a prototype.
For question 5, I think it might be best if you answer that one. It is based on YOUR opinion and what YOU use. If you are asked about it, they will know it's from you and your opinion. Lol! But I hope I helped you out with the other questions! ;)

An arc on a circle of radius 10 has an arc length of 49/9 . What is the degree measure of the corresponding central angle?
Hope this help!!!
Have a nice day!!!
Answer:
Central angle = 98 degrees
Step-by-step explanation:
Radius (r) = 10 Arc length = 49[tex]\pi[/tex]/9
Let 0 be the central angle
Arc Length = 2[tex]\pi[/tex]r0/360
49[tex]\pi[/tex]/9 = 2[tex]\pi[/tex]r0/360
49[tex]\pi[/tex]/9 = [tex]\pi[/tex]x0/18
49[tex]\pi[/tex]/9 x 18/[tex]\pi[/tex] = 0
0 = 49x2
0 = 98 degrees
Find the value of x in each triangle. Please help me <33
Answer:
x = 11
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
5x + 4 + 6x - 3 + 4x + 14 = 180 ← collect like terms on left side
15x + 15 = 180 ( subtract 15 from both sides )
15x = 165 ( divide both sides by 15 )
x = 11

Using the trend line y = 2x + 15, for the data shown, complete the residual table.
Given:
The data table is given.
The equation of trend line is:
[tex]y=2x+15[/tex]
To find:
Values for residual table.
Solution:
Formula for residual:
[tex]Residual=\text{Observed value}-\text{Predicted value}[/tex]
The equation of trend line is:
[tex]y=2x+15[/tex] ...(i)
Substituting [tex]x=5[/tex] in (i), we get
[tex]y=2(5)+15[/tex]
[tex]y=10+15[/tex]
[tex]y=25[/tex]
The value of y from the table at [tex]x=5[/tex] is 25. So,
[tex]Residual=25-25[/tex]
[tex]Residual=0[/tex]
Similarly,
Substituting [tex]x=6[/tex] in (i), we get
[tex]y=2(6)+15[/tex]
[tex]y=12+15[/tex]
[tex]y=27[/tex]
The value of y from the table at [tex]x=6[/tex] is 28. So,
[tex]Residual=28-27[/tex]
[tex]Residual=1[/tex]
Substituting [tex]x=7[/tex] in (i), we get
[tex]y=2(7)+15[/tex]
[tex]y=14+15[/tex]
[tex]y=29[/tex]
The value of y from the table at [tex]x=7[/tex] is 29. So,
[tex]Residual=29-29[/tex]
[tex]Residual=0[/tex]
Substituting [tex]x=8[/tex] in (i), we get
[tex]y=2(8)+15[/tex]
[tex]y=16+15[/tex]
[tex]y=31[/tex]
The value of y from the table at [tex]x=8[/tex] is 30. So,
[tex]Residual=30-31[/tex]
[tex]Residual=-1[/tex]
Substituting [tex]x=9[/tex] in (i), we get
[tex]y=2(9)+15[/tex]
[tex]y=18+15[/tex]
[tex]y=33[/tex]
The value of y from the table at [tex]x=9[/tex] is 32. So,
[tex]Residual=32-33[/tex]
[tex]Residual=-1[/tex]
Therefore, the complete residual table is:
x : 5 6 7 8 9
Residuals : 0 1 0 -1 -1
