The correct inequality and number line that model the situation above is:
10 ≤ weight of boxes ≤ 20
and the correct graph is: Graph A
Step-by-step explanation:The desired weight of raisins is: 15 ounces.
As the weight of the raisins packed differs by a maximum of 5 ounces.
This means that the weight of the raisins packed could either be less by 5 ounces or more by 5 ounces.
i.e. Weight of raisins could be minimum= 15-5=10 ounces.
and weight of raisins could be maximum= 15+5=20 ounces.
Hence, the inequality that will hold true is:
10 ≤ weight of boxes ≤ 20
and the graph that describe this situation is attached to the answer.

The path of a diver diving into the water is approximately parabolic. Diving Timelapse The function h(t)=-2t^2+3t+9 h ( t ) = − 2 t 2 + 3 t + 9 most closely represents the height (h) of the diver in feet after t seconds. How high does the diver reach? Round to the nearest tenth. Hint: Make sure you include units. A space is needed between the number and unit. Example: 34.8 feet
Answer:
10.125 feet
Step-by-step explanation:
h(t) = -2t² + 3t + 9
The maximum height is at the vertex of the parabola. For a parabola ax² + bx + c, the vertex is at x = -b/(2a).
t = -3 / (2×-2)
t = 3/4
h(3/4) = -2(3/4)² + 3(3/4) + 9
h(3/4) = -9/8 + 9/4 + 9
h(3/4) = 81/8
h(3/4) = 10.125 feet

Match each polynomial function with one of its factors.
f(x) = x3 − 3x2 − 13x + 15
f(x) = x4 + 3x3 − 8x2 + 5x − 25
f(x) = x3 − 2x2 − x + 2
f(x) = -x3 + 13x − 12
x − 2 -->
x + 3 -->
x + 4 -->
x + 5 -->
Answer:
[tex]x-2 => f(x)=x^{3}-2x^{2}-x+2\\x+3=>f(x)=x^{3}-3x^{2} -13x+15\\x+4=>f(x)=-x^{3}+13x-12\\x+5=>f(x)=x^{4}+3x^{3}-8x^{2}+5x-25[/tex]
Step-by-step explanation:
The value of a function will be zero if the factor is put in it. In order to check whether a factor is of a function or not we will put the value of x from that factor in the function:
So
x-2 = 0 => x=2
Putting in first function
[tex]x^{3}-3x^{2} -13x+15\\=(2)^{3}-3(2)^{2} -13(2)+15\\=8-3(4)-26+15\\=8-12-26+15\\=23-38\\=-15 \neq 0\\[/tex]
So x-2 is not a factor of first function.
Putting in second function
[tex]f(x)=x^{4}+3x^{3}-8x^{2}+5x-25\\ =(2)^{4}+3(2)^{3}-8(2)^{2}+5(2)-25\\=16+3(8)-8(4)+10-25\\=16+24-32+10-25\\=-7\neq 0[/tex]
So x-2 is also not a factor of second function.
Putting in third function:
[tex]f(x)=x^{3}-2x^{2}-x+2\\ =(2)^{3}-2(2)^{2}-2+2\\=8-2(4)-2+2\\=8-8-2+2\\=0[/tex]
So x-2 is factor of third function.
...........................
For x+3
x+3=0
x=-3
First function:
[tex]f(x)=x^{3}-3x^{2} -13x+15\\=(-3)^{3}-3(-3)^{2} -13(-3)+15\\=-27-3(9)+39+15\\=-27-27+39+15\\=-54+54\\=0\\[/tex]
So x+3 is a factor of first function.
.............................
For x+4
x+4=0
x=-4
As we have already found the factors of first and third function, we will now only check second and fourth function.
[tex]f(x)=x^{4}+3x^{3}-8x^{2}+5x-25\\ =(-4)^{4}+3(-4)^{3}-8(-4)^{2}+5(-4)-25\\=256+3(-64)-8(16)-20-25\\=256-192-128-20-25\\-109\neq 0[/tex]
So x+4 is not a factor of second function.
Putting in fourth function:
[tex]f(x)=-x^{3}+13x-12\\ =-(-4)^{3}+13(-4)-12\\=64-52-12\\=64-64\\=0\\[/tex]
So x+4 is a factor of fourth function
..........................
For x+5=0
x=-5
Since only one function is remaining we'll only check for that.
[tex]f(x)=x^{4}+3x^{3}-8x^{2}+5x-25\\ =(-5)^{4}+3(-5)^{3}-8(-5)^{2}+5(-5)-25\\=625+3(-125)-8(25)-25-25\\=625-375-200-25-25\\=0\\[/tex]

Answer:
B. The sum of the squares of the two smaller sides is equal to the square of the third side.
Step-by-step explanation:
It can be helpful to recognize that the given side lengths, 12, 16, 20 are in the ratio 3:4:5, a recognizable Pythagorean triple. That is, you may know already that the triangle is a right triangle and the sum of squares of the short sides is equal to the square of the longest side (choice B).
In case you aren't aware of common Pythagorean triples, or didn't recognize these numbers, you can try the options to see which fits.
A. The sum of the two smaller sides is 12 +16 = 28. It is NOT equal to the third side, 20.
__
B. The sum of the squares of the two smaller sides is 12^2 + 16^2 = 144 + 256 = 400. This IS equal to the square of the third side: 20^2 = 400.
__
C. The absolute value of the difference between the squares of the two smaller sides is |256 -144| = 112. This is NOT equal to the square of the third side, 20^2 = 400.
__
D. The sum of the squares of the two smaller sides is 400 (as above). It is NOT equal to the third side, 20.
___
The only answer choice that fits is choice B.

In the figure, m∠1 = m∠2 = 22 and m∠3 = m∠4 = 123. From this, you can conclude that m∠TKL = _____
a. 22.
b. . 57.
c. 35.
d. 47.
Answer:
57°
Step-by-step explanation:
Angle 3 is supplementary to angle TKL. That means they add up to 180°. Therefore, 180° - 123° = 57°
Answer:
57°
Step-by-step explanation:
You can notice that by putting ∠3 and ∠TKL together you have a flat angle.
A flat angle has 180 degrees.
so, you can say that m∠3 and m∠TKL add 180 degrees, then they are supplementary angles.
Remember: Two angles are supplementary if they add 180 degrees.
Then, as you know m∠3=123°:
m∠3 + m∠TKL=180°
123 + m∠TKL=180°
m∠TKL=180° - 123°
m∠TKL=57°

Convert the exact rectangular coordinates to polar coordinates.
if the rectangular coordiante is (x,y) and the polar coordinate is (R,t), then they are related as follows:
R^2=x^2+y^2
tant=y/x
1.(pi,pi/4)
here, R=
[tex] \sqrt{ {\pi}^{2} + { (\frac{\pi}{4} })^{2} } = \sqrt{ \frac{17 {\pi}^{2} }{16} } = \frac{\pi}{4} \sqrt{17} \\tant = \frac{ \frac{\pi}{4} }{4} \\ t = {tan}^{ - 1} \pi = 89.682[/tex]
therefore the polar form of Q.1 is
(pi sq. root 17/4,89.682°)
you can do 2 in similar way.
A series of transformations on quadrilateral S resulted in quadrilateral T.
~The angle measures of quadrilaterals T are congruent to those of quadrilateral S
~The side lengths of quadrilateral T are twice as long as those of quadrilateral S
Which transformation on quadrilateral S must be included to result in quadrilateral T?
A) Dilation
B) Rotation
C) Reflection
D) Translation
Dilation since one image is bigger than the other
A dilation transformation must be included to result in quadrilateral T.
Explanation:To result in quadrilateral T, a dilation transformation must be included. A dilation is a transformation that changes the size of the figure without changing its shape. In this case, the side lengths of quadrilateral T are twice as long as those of quadrilateral S, indicating a scaling factor of 2. Therefore, a dilation is needed to scale up the size of quadrilateral S by a factor of 2 to obtain quadrilateral T.

Answer:
BC = 52
Step-by-step explanation:
The point of the question is to have you recognize and use the fact that the tangent segments from the same point are of equal length. That lets you write the equation ...
4x +8 = 2(3x -7) . . . BC = BA
2x +4 = 3x -7 . . . . . divide by 2
11 = x . . . . . . . . . . . . add 7-2x
The length of segment BC is computed using this value of x:
BC = 4x +8 = 4·11 +8
BC = 52

To find the missing length, use the Pythagorean theorem by setting up an equation with the given lengths in a right triangle. Solve for the missing length using the equation and determine the correct answer.
Explanation:To find the missing length, we need to use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. Let's assume the missing length is represented by 'x'. Using the theorem, we can set up the equation as follows:
a = 16b = 30c = xWe can solve for 'x' by substituting the given lengths into the equation and solving for 'x'.
x2 = a2 + b2
x2 = 162 + 302
x2 = 256 + 900
x2 = 1156
x = √1156
x = 34
Therefore, the missing length indicated is 34. Option B) 36 is not the correct answer.

The coordinates of the vertices of triangle cde are c (-3, 1), d (-1, 4) and e (-6, 4). a transformation applied to triangle cde creates a congruent triangle sqr. the new coordinates of two vertices are q(-1, 6) and r(-6, 6). what are the coordinates of s?
Answer:
The coordinates of point s are (-3 , 3)
Step-by-step explanation:
* Lets revise some transformation
- If the point (x , y) translated horizontally to the right by h units
then the new point = (x + h , y)
- If the point (x , y) translated horizontally to the left by h units
then the new point = (x - h , y)
- If the point (x , y) translated vertically up by k units
then the new point = (x , y + k)
- If the point (x , y) translated vertically down by k units
then the new point = (x , y - k)
* Now lets solve the problem
∵ The vertices of triangle cde are c (-3 , 1) , d (-1 , 4) , e (-6 , 4)
∵ The new coordinates of two vertices are q (-1 , 6) , r (-6 , 6)
- The image of point d is q and the image of point e is r
∵ Point d = (-1 , 4) and point q = (-1 , 6)
∵ Point e = (-6 , 4) and point r = (-6 , 6)
- The x-coordinate has no change but the y-coordinate added by 2
∴ The triangle cde translated vertically up by 2 units to create the
congruent triangle sqr
- Lets translate point c two units up to find the coordinates of point s
∵ Point c = (-3 , 1)
∴ Poin s = (-3 , 1 + 2) = -3 , 3)
* The coordinates of point s are (-3 , 3)

Of the 500000 people (age 16+) in a particular country 300000 people are in the labor force. of the 240000 are employed and 60000 are unemployed what is the unempoyment rate
Answer:
12%
Step-by-step explanation:
60000 people are unemployed, out of 500000 people.
That means that 60000/500000 of the population is unemployed.
Simplify: 60000/500000 = 6/50 = 0.12 = 12%
The overall unemployment rate is will be 12% based on the given data.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Total people = 5000000
40000 are employed and 60000 are unemployed out of 300000 people are in the labor force.
The % unemployment rate = (60000)/500000 x 100 = 12%
Hence "The overall unemployment rate is will be 12% based on the given data".

Nicole runs a farm stand that sells bananas and peaches. Each pound of bananas sells for $2 and each pound of peaches sells for $3.25. Nicole sold 3 more pounds of bananas than pounds of peaches and made $231.75 altogether. Write a system of equations that could be used to determine the number of pounds of bananas sold and the number of pounds of peaches sold. Define the variables that you use to write the system.
Answer:
The required system of equations is:
2x + 3.25y = 231.75
x = y + 3
where x is the number of pounds of bananas and y is the number of pounds of peaches
Explanation:
1- Defining the variables:
Assume that the number of pounds of bananas sold is x
Assume that the number of pounds of peaches sold is y
2- Setting the system of equations:
We are given that:
i. Each pound of bananas sells for $2
Money gained from selling x pounds of bananas is 2x
ii. Each pound of peach sells for $3.23
Money gained from selling y pounds of peaches is 3.25y
iii. Nicole made $231.75 in total. This means that:
2x + 3.25y = 231.75 .................> equation I
iv. Nicole sold 3 more pounds of bananas than pounds of peaches. This
means that:
pounds of bananas = pounds of peaches + 3
x = y + 3 ..................> equation II
3- Solving the equations (if required):
In equation II, we have: x = y + 3
Substitute with equation II in equation I and solve for y as follows:
2x + 3.25y = 231.75
2(y+3) + 3.25y = 231.75
2y + 6 + 3.25y = 231.75
5.25y = 231.75 - 6
5.25y = 225.75
y = 43
Substitute with y in equation II to get x:
x = y + 3
x = 43 + 3 = 46
Based on the above:
Number of pounds of bananas = x = 46 pounds
Number of pounds of peaches = y = 43 pounds

Answer:
(x + 1) (3x - 1)
Step-by-step explanation:
Using the AC method, here a = 3, b = 2, and c = -1.
ac = 3 * -1 = -3
Factors of -3 that add up to +2 are +3 and -1.
Divide by a: +3/3, -1/3
Reduce: +1/1, -1/3
So the factors are x + 1 and 3x - 1.
3x² + 2x - 1 = (x + 1) (3x - 1)
Answer:
x = 1/3 or x = -1
Step-by-step explanation:
3x^2 + 2x - 1
=> 3x^2 + 3x - 1x - 1 product = -3 sum = 2
=> 3x( x + 1 ) - 1(x + 1 )
=> (3x - 1) (x + 1)
3x = 1

D. The pressure on a gas varies inversely with its temperature at constant volume.
Answer:
.A.The volume of a gas varies directly with its temperature at constant pressure.
Step-by-step explanation:
This law is expressed mathematically as;
V₁ /T₁ =V₂/T₂ where
V₁=initial volume
T₁=initial absolute temperature
V₂=final volume
T₂=final absolute temperature
The temperature is converted to Kelvin when doing calculations where;
0°c = 273 K
An application of this law in real world examples could be when a ball is left outside overnight it the cold, the ball shrinks a little in its volume due to decreased temperatures.
