Graph the function <br> y=4(2^x+3)-1<br> and <br> y=-2(3^x-4)+1
kondaur [170]

The graphs of the functions y = 4(2ˣ + 3) - 1 and y = - 2(3ˣ - 4) + 1 are plotted on the graph.

<h3>What is function?</h3>

A function is a relation between a dependent and a independent variable, such that the dependent variable depends upon the independent one for its existence.

Given are the following functions -

y = 4(2ˣ + 3) - 1

y = - 2(3ˣ - 4) + 1

We have the following functions -

y = 4(2ˣ + 3) - 1

y = - 2(3ˣ - 4) + 1

Refer to the graph attached. The graph of red color represents the function y = 4(2ˣ + 3) - 1 and the graph of blue color represents the function y = - 2(3ˣ - 4) + 1. It can be seen that the graphs are symmetrical about the line y = 10.

Therefore, the graphs of the functions y = 4(2ˣ + 3) - 1 and y = - 2(3ˣ - 4) + 1 are plotted on the graph.

Find the zeros of each function by using a graph and a table. f(x)=x^2+2x–24.
Alborosie

Explanation

Step 1

f(x)=x^2+2x-24

Zeros

A(-6,0) B(4,0)

because

\begin{gathered} f(x)=x^2+2x-24 \\ f(-6)=(-6)^2+2(-6)-24=36-12-24=0 \\ f(4)=4^2+2\cdot4-24=16+8-24=0 \end{gathered}

Step 2

table

\begin{gathered} (-6,0) \\ (4,0) \\ f(-1)=-1^2+2\cdot-1-24=1-2-24=-25 \\ (1,-25) \\  \end{gathered}

I hope this helps you

Subtract. Express your answer in lowest form. 8 1/4 minus 5 2/3 a. 3 5/12 b. 3 7/12 c. 2 5/12 d. 2 7/12
valina [46]

Answer:

D. 2 7/12

Step-by-step explanation:

8 1/4 - 5 2/3

Turn to improper fractions.

33/4 - 17/3

Make the denominators equal.

99/12 - 68/12

Subtract the fractions since denominators are equal.

31/12

= 2 7/12

A random sample of 28 fields of spring wheat has a mean yield of 44.7 bushels per acre and standard deviation of 6.96 bushels pe
Bingel [31]

Answer:

44.7-2.052\frac{6.96}{\sqrt{28}}=42.001    

44.7+2.052\frac{6.96}{\sqrt{28}}=47.399    

And the confidence interval would be between 42.001 and 47.399

Step-by-step explanation:

Information given

\bar X=44.7 represent the sample mean for the sample  

\mu population mean

s=6.96 represent the sample standard deviation

n=28 represent the sample size  

Confidence interval

The confidence interval for the mean is given by the following formula:

\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}   (1)

The degrees of freedom are given by:

df=n-1=28-1=27

The Confidence interval is 0.95 or 95%, the significance is \alpha=0.05 and \alpha/2 =0.025,the critical value for this case would be t_{\alpha/2}=2.052

And replacing we got:

44.7-2.052\frac{6.96}{\sqrt{28}}=42.001    

44.7+2.052\frac{6.96}{\sqrt{28}}=47.399    

And the confidence interval would be between 42.001 and 47.399
