To plot the graph of the function:
[tex]h(x)=8|x+1|-1[/tex]According to your graphing software, we need to find the smallest value of the function, and any point at the positive slope side of the function. Let's start with the minimum point. Let's use the general formula for an absolute value function:
[tex]f(x)=a|x+b|+c[/tex]The coefficients 'b' and 'c' determinates how much the function was translated from the origin. The 'b' determinates in the x-axis, and the 'c' determinates in the y-axis.
If the 'b' is positive, the function translated to the left, if it is negative the function translated to the right.
If the 'c' is positive the function went up, and if it is negative it went down.
Now let's analyze our h(x) function. Our coefficients are:
[tex]\begin{cases}b=1 \\ c=-1\end{cases}[/tex]Which means our minimum point is
[tex](-1,-1)[/tex]Now, we just need to calculate any point to the right of x = -1.
Let's calculate for x = 0.
[tex]h(0)=8|0+1|-1=8-1=7[/tex]The second point is (0,7)
find the value(s) of c guaranteed by the Mean Value Theorem for Integrals for the function over the given interval.
Remember that
If f is continuous over [a,b] and differentiable over (a,b), then there exists c∈(a,b) such that
[tex]f^{\prime}(c)=\frac{f(b)-f(a)}{b-a}[/tex]In this problem, we have the function
[tex]f(x)=\frac{9}{x^3}[/tex]over the interval [1,3]
so
f(a)=f(1)=9/(1)^3=9
f(b)=f(3)=9/(3)^3=1/3
substitute
[tex]f^{\prime}(c)=\frac{\frac{1}{3}-9}{3-1}=\frac{-\frac{26}{3}}{2}=-\frac{26}{6}=-\frac{13}{3}[/tex]Find out the first derivative f'(x)
[tex]f^{\prime}(x)=-\frac{27}{x^4}[/tex]Equate the first derivative to -13/3
[tex]\begin{gathered} -\frac{27}{x^4}=-\frac{13}{3} \\ \\ x^4=\frac{27*3}{13} \\ \\ x=1.58 \end{gathered}[/tex]therefore

2. An account is opened with $28000 earning12% interest compounded yearly. What is thebalance in the account after 4 years?
The principal is $28000 with rate 12% compounded yearly .
To determine the balance after 4 years,

if dyllan makes 7 out of 10 free throws on any given day what is the probability he will make his next free throw? ( write your answers as a precent.)
Answer:
70%
Explanation:
The probability can be calculated as the number of free throws that Dylan makes divided by the total number of free throws.
So, if Dylan makes 7 out of 10 free throws, the probability can be calculated as:
[tex]P=\frac{7}{10}=0.7[/tex]Then, to know the probability as a percent, we need to multiply 0.7 by 100% to get:
P = 0.7 x 100% = 70%
Therefore, the answer is 70%

13x-6y=2
3x-4y=-10
(Write as ordered pair)
Step-by-step explanation:
let's multiply the first equation by 2 and the second equation by -3, and then we add them together :
26x - 12y = 4
-9x +12y = 30
-------------------------
17x 0 = 34
x = 2
and now we use one of the original equations to solve for y :
3×2 - 4y = -10
6 - 4y = -10
-4y = -16
y = 4
the solution is (2, 4).

the profit p can be modeled by the function p = -15t² + 600t + 50, where t represents the ticket price in dollars.
a. What price yields the maximum profit?
b. What is the maximum profit?
Based on the given function,
a) The price that yields the maximum profit is $20.
b) The maximum profit is $6,050
Function
Function defines the relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output.
Given,
A rock club's profit from booking local bands depends on the ticket price. Using past receipts, the owners find that the profit p can be modeled by the function p = -15t² + 600t + 50, where t represents the ticket price in dollars.
Here we need to find the price that yields maximum profit and the amount of maximum profit.
In order to find the price that yield the maximum profit, we have to find the value of t, that can be obtained by using the formula,
t = -b/2a
According to the given function the values of a = -15 and the value of b = 600
Apply these values on the given function then we get,
t = -600/ 2(-15)
t = -600/-30
t = 20
Therefore, the price that yields the maximum profit is $20.
Now, we need to find the maximum profit, by apply the value of t as 20 in the given function then we get,
p = -15(20)² + 600(20) + 50
P = -15(400) + 12000 + 50
p = -6000 + 12000 + 50
p = 6000 + 50
Therefore, the maximum profit is $6,050.

Samuel has 10 coins that add up to $3.80. Some are 50 cent and the rest are 20 cent coins. How many 50 cent coins does he have?
Answer:
6 coins of 50cent
Step-by-step explanation:
Information we have:
1. x number of 50cent and y number of 20cent added up to 380cent.
2. x and y is 10coins
eq1 : 50x + 20y = 380
eq2: x + y = 10
write eq2 to y in term of x
y = 10 - x -> eq3
replace eq3 into eq1
50x + 20(10 - x) = 380
50x + 200 - 20x = 380
50x -20x = 380 -200
30x = 180
x = 180/30 = 6

What is -2(-x+5y-4) (simplify equation)
Using the distributed property, the simplified form of -2(-x+5y-4) is 2x-10y+8.
In the equation question,
The given expression is -2(-x+5y-4).
We have to simplify the given expression.
We simplify the given expression using the distributed method.
In the distributed method we have to multiply the number outside the bracket to all the terms that are inside the bracket.
As a(b+c) = ab+bc
In the given question there is -2 outside the bracket and -x+5y-4 is inside the bracket.
To simplify the given expression we multiply -2 to each term inside the bracket.
-2(-x+5y-4) = (-2)×(-x)+(-2)×5y-(-2)×4
Simplifying
-2(-x+5y-4) = 2x+(-10)y-(-8)
Simplifying the bracket
-2(-x+5y-4) = 2x-10y+8
Hence, the simplified form of -2(-x+5y-4) is 2x-10y+8.

10 less than 7 times a number is the same as 3 times the number plus 18
Answer:
yes, it is the same
Step-by-step explanation:
7x - 10 = 3x + 18
7x-10+10 = 3x + 18 + 10
7x = 3x + 28
7x - 3x = 3x - 3x + 28
4x = 28
4x ÷ 4 = 28 ÷ 4
x=7
Plug x back in and check the answer.
7x-10 = 3x+18
7(7)-10 = 3(7)+18

The population of Phoenix , Arizona will reach 1.5 million in the year 2005 .
In the question ,
it is given that ,
the equation , modelling the the population P of Phoenix, Arizona (in thousands) from 1970 through 2000 is
P = 590[tex]e^{0.027\times t}[/tex]
where t represents the year corresponding to 1970 .
we need to find the time required for the population to reach 1.5 million.
since population is represented in thousands , so ,
1.5 million = 1500000 will be taken as 1500 .
Substituting P = 1500 in the equation ,
we get ,
1500 = 590[tex]e^{0.027\times t}[/tex]
1500/590 = [tex]e^{0.027\times t}[/tex]
2.5423 = [tex]e^{0.027\times t}[/tex]
taking ㏑ both the sides , we get
㏑(2.5423) = (0.027t)×㏑(e)
0.93306 = 0.027×t
t = 0.93306/0.027
t = 34.55 years
t ≈ 35 years
the year will be 1970 + 35 = 2005 .
