Describe how to determine the average rate of change between x = 1 and x = 3 for the function f(x) = 3x3 + 1.
Need this quick please!
Answer:
9x^2+9xh+3h^2
Step-by-step explanation:
The general rate of change can be found by using the difference quotient formula. To find the average rate of change over an interval, enter a function with an interval: f ( x ) = x 2 , [ 2 , 3 ]
The shortest distance between any two points is a straight line.
a. True
b. False
Answer:
True
Step-by-step explanation:
The answer to this question is true.
It is worthy to note that in any two points, we have exactly one line segment that connects them together. Now the The distance that lies between both of these points is the length of this line segment which connects them. Also this distance is never negative. It is always positive.
Archimedes was the first to say that the shortest distance between two points is a straight line.

An elementary school is offering 3 language classes: one in Spanish, one in French, and one in German. These classes are open to any of the 103 students in the school. There are 37 in the Spanish class, 38 in the French class, and 21 in the German class. There are 17 students that in both Spanish and French, 7 are in both Spanish and German, and 10 are in both French and German. In addition, there are 4 students taking all 3 classes.
Required:
a. If a student is chosen randomly, what is the probability that he or she is not in any of the language classes?
b. If a student is chosen randomly, what is the probability that he or she is taking exactly one language class?
c. If 2 students are chosen randomly, what is the probability that at least 1 is taking a language class?
Answer:
0.3689 ; 0.3592 ; 0.6301
Step-by-step explanation:
Spanish = S
French = F
German = G
n(S) = 37 ; n(F) = 38 ; n(G) = 21
n(SnF) = 17 ; n(SnG) = 7 ; n(FnG) = 10
n(SnFnG) = 3
n(SnF) only = 17 - 3 = 14 ;
n(SnG) only = 7 - 3 = 4 ;
n(FnG) only = 10 - 3 = 7
n(S) only = 37 - (14 + 3 + 4) = 16 ;
n(F) only = 38 - (14 + 3 + 7) = 14;
n(G) only = 21 - (7 + 3 + 4) = 7
Probability of not being in any language class :
Number of students not in any class (x)
(16+7+14+14+4+7+3+x) = 103
65 + x = 103
x = 103 - 65
x = 38
Probability, P = required outcome / Total possible outcomes
P(not in any class) = 38 / 103
= 0.3689
2.) probability of taking exactly one class :
Either Spanish or German or French
16/103 + 7/103 + 14/103 = 37/103 = 0.3592
3.) probability that atleast one of two students is taking a language class :
Probability that a student chosen is taking a language class :
Number of students taking a language class / total number of students
= 65 / 103
= 0.631
[P(takes class) * p(does not take class)] + [p(takes class) * p(takes class)]
(0.631 * 0.3689) + (0.631 * 0.631) = 0.6301

if I had $13 and my mom gave $10 my dad gave $30 my grandma grandpa and aunt gave me $100 and I had another $7 what would that make me have
Answer: $160
Step-by-step explanation: 13 + 10 + 30 + 100 + 7
13 + 10 =23
23 + 30 = 53
53 + 100 = 153
153 + 7 = 160
Kane Manufacturing has a division that produces two models of fireplace grates, x units of model A and y units of model B. To produce each model A requires 2 lb of cast iron and 7 min of labor. To produce each model B grate requires 4 lb of cast iron and 4 min of labor. The profit for each model A grate is $1.50, and the profit for each model B grate is $2.40. If 920 lb of cast iron and 1620 min of labor are available for the production of grates per day, how many grates of each model should the division produce per day in order to maximize Kane's profits P?
P = ? subject to the constraints
cast iron ?
labor ?
x ≥ 0
y ≥ 0
Answer:
(140, 160)
Step-by-step explanation:
Let x represent model A and y represent model B.
2 lb of cast iron is needed for model A while 4 lb of cast iron is needed for model B. 920 lb of cast iron is available for production. This can be represented by the constraint:
2x + 4y ≤ 920 (1)
7 min of labor is needed for model A while 4 min of labor is needed for model B. 1620 min of labor is available for production per day. This can be represented by the constraint:
7x + 4y ≤ 1620 (2)
Also, x ≥ 0 , y ≥ 0
Plotting the constraints using geogebra app, The points that satisfy these constraints are:
(0, 230), (231.42, 0), (0,0) and (140, 160)
The profit for each model A grate is $1.50, and the profit for each model B grate is $2.40. The profit equation is:
Profit = 1.5x + 2.4y
We are to maximize profit. Hence:
At (0,0); max Profit = 1.5(0) + 2.4(0) = 0
At (0,230); max Profit = 1.5(0) + 2.4(230) = 552
At (231.42,0); max Profit = 1.5(231.42) + 2.4(0) = 347
At (140,160); max Profit = 1.5(140) + 2.4(160) = 594
The maximum profit is at (140, 160)

Find the two numbers.⠀[tex]\sf{\bold{\purple{\underline{\underline{Solution}}}}}[/tex]
⠀⠀⠀⠀
In questions given,One number is six more than a second number.
if second number is a
first number is a+6.
and,
four times the first is 10 less than 6 times the second.
So,
4×(a+6)=6a-10
we have to solve this.
[tex]\bold{4\times (a+6)=6a-10 }[/tex]
[tex]\bold{4a+24=6a-10 }[/tex]
[tex]\bold{6a-4a=24+10 }[/tex]
[tex]\bold{2a=34 }[/tex]
[tex]\bold{ a=\dfrac{34}{2} }[/tex]
[tex]\bold{ a=17 }[/tex]
we,get our second number =a=17.
So,
first number =a+6=17+6=23

A bunny can jump 2/3 of a meter in a single jump!
How many jumps will the bunny need in order to go to 12 meter?
please explain your work
Answer:
18 jumps (if we are talking about total here)
Step-by-step explanation:
2/3 can be divided into 12/1 , and to divide you have to flip 2/3 into 3/2 and multiply the fractions. You should be left with 36/2 which simplified is 18/1, which equals 18 jumps.

what theorem can be used to prove the 2 triangles similar?
Answer:
C. SSS
Step-by-step explanation:
[tex] \frac{AB}{SQ} = \frac{AC}{SR} = \frac{BC}{QR} = 2 [/tex]
Thus, the ratio of the corresponding side lengths of both triangles are equal. This implies that all three corresponding side lengths of both triangles are proportional to each other.
Consequently, based on the SSS Criterion, we can conclude that both triangles are similar to each other.
