What can you say about the function that generated the following table of values
best answer is b = it has exactly 1 x intercept
Answer:
B.
Step-by-step explanation:
We know that for x-intercept the graph crosses x-axis i.e the value of y = 0.
As in the table, the value of y is changing from negative to positive, so it will obtain the value y = 0 for some vale of x.
Therefore, this function will have only one x-intercept.
Hence, option A, C, D are discarded and option B is correct.

A stick 42 inches long is broken into two pieces, so that one piece is twice as long as the other one. How long are the two pieces ?
The answer is 14 inches and 28 inches:
Total length of stick = 42 inches.
Let the shorter piece be x inches.
Thus, the longer piece is 2x.
2x + x = 42
3x = 42
x = 14
Therefore, the length of the two pieces are 14 inches and 28 inches.

Alexis put $2000 in a savings account. After 4 years, she had $2543 in the account. What rate of interest did she earn? Use the formula A= Pe^rt, where A is the ending amount, P is the principal (initial amount), r is the interest rate, and t is time.
Answer:
Rate of interest = 6%
Step-by-step explanation:
Alexis put $2000 in a savings account. After 4 years, she had $2543 in the account.
Use the formula,
[tex]A=Pe^{rt}[/tex]
[tex]P\rightarrow \$2000[/tex]
[tex]r\rightarrow ?[/tex]
[tex]A\rightarrow \$2543[/tex]
[tex]t\rightarrow 4\text{ years}[/tex]
Substitute the value into formula and solve r
[tex]2543=2000e^{4r}[/tex]
[tex]e^{4r}=1.2715[/tex]
Apply ln both sides
[tex]4r\ln(e)=\ln(1.2715)[/tex]
[tex]r=0.06[/tex]
Rate of interest = 6%
Hence, The rate of interest is 6%
Aiden calculated the area of triangle QRS below by finding half the product of 1.5 and 1.1.
Answer: The correct option is
(B) Aiden should have found half the product of 1.1 and 5.4 because the 1.5 line is not perpendicular to 1.1 line.
Step-by-step explanation: Given that Aiden calculated the area of triangle QRS by finding half the product of 1.5 and 1.1.
We are to select the correct option which states the error made by Aiden.
The AREA of a triangle is given by
[tex]A=\dfrac{1}{2}\times \textup{base}\times \textup{altitude},[/tex]
where the altitude is perpendicular to the base.
In ΔQRS, the length of the base is given by
b = QS = 0.9 + 4.5 = 5.4 units
and
the length of the altitude is given by
h = 1.1 units.
So, the area of the triangle QRS will be
[tex]A=\dfrac{1}{2}\times b\times h=\dfrac{1}{2}\times 5.4\times 1.1[/tex]
Therefore, the area of ΔQRS will be calculated by finding half the product of 1.1 and 5.4.
So, Aiden made the error by finding half the product of 1.5 and 1.1, because 1.5 line is not perpendicular to 1.1 line.
Thus, Aiden should have found half the product of 1.1 and 5.4 because the 1.5 line is not perpendicular to 1.1 line.
Option (B) is correct.

the price of 9-volt batteries is increasing according to the function below, where t is years after January 1, 1980. During what year will the price reach $4? use formula P(t)=1.1*e^0.047t A.)2007 B.)2005 C.)2003 D.)2009
Answer:
The option A.) 2007 is correct
Step-by-step explanation:
The formula which is to be used is given :
[tex]P(t) = 1.1\cdot e^{0.047t}[/tex]
where P(t) is the function of time t and t is the time in years after January 1 , 1980
Now, we need to find the year when the price will reach $4
So, substituting P(t) = 4 and finding the value of t from the given equation.
[tex]\implies 4=1.1\cdot e^{0.047t}\\\\\implies 3.64=e^{0.047t}\\\\\text{Taking natural log ln on both the sides}\\\\\implies \ln 3.64=\ln e^{0.047t}\\\\\implies 1.29=0.047\cdot t\\\\\implies t = 27.49[/tex]
So, t = 27.49 which is approximately equals to 27.5 years
So, 27.5 years after January 1, 1980 is the year 2007
Hence, The price will reach $4 in the year 2007
Therefore, The option A.) 2007 is correct
One ordered pair $(a,b)$ satisfies the two equations $ab^4 = 12$ and $a^5 b^5 = 7776$. what is the value of $a$ in this ordered pair?
To find the value of a in the ordered pair (a,b), we can solve the given equations. Substituting ab^4 with 12 in the second equation, we get a^5 (12)^5 = 7776. Solving for a gives a = 0.03125^(1/5) = 0.5.
Explanation:To find the value of a in the ordered pair (a,b), we can solve the given equations.
From the first equation, ab^4 = 12, we can substitute ab^4 with 12 in the second equation:
a^5 b^5 = 7776
This gives us:
a^5 (12)^5 = 7776
12^5 = 12 * 12 * 12 * 12 * 12 = 248,832
Dividing both sides of the equation by (12^5) gives:
a^5 = 7776 / (12^5) = 7776 / 248,832 = 0.03125
Taking the fifth root of both sides gives:
a = 0.03125^(1/5) = 0.5

Slope (12,-18),(11,12)
The slope of the line passing through the points (12, -18) and (11, 12) is calculated using the formula for slope (y2 - y1) / (x2 - x1). The result is -30.
Explanation:The subject of this question is Mathematics, more specifically the topic of 'Slope of a Line'. The grade level appears to be High School.
To answer the question 'Find the slope for the given coordinates (12,-18) and (11,12)', we use the formula to calculate the slope between two points which is (y2 - y1) / (x2 - x1). Let's take (12, -18) as (x1, y1) and (11, 12) as (x2, y2). Now we just input the values into the formula:
Slope (m) = (12 - (-18)) / (11 - 12).
This simplifies to Slope (m) = 30 / -1 = -30.
So, the slope of the line passing through the points (12, -18) and (11, 12) is -30.
