Answer:
The correct answer is A. Vertical compress by a factor of 5
Step-by-step explanation:
When graphed without the 5, the curve is very wide, but when the 5 is added, the curve compresses and narrows itself, therefore a vertical compress occurs by the factor of 5.

Solve the following equation for a. Be sure to take into account whether a letter is
capitalized or not.
Answer:
[tex]a=\frac{m}{(q+r^2)}[/tex]
Step-by-step explanation:
We begin with the equation [tex]qa+r^2a=m[/tex] for which we need to solve for a.
The first thing that we can do is to factor out the a from both terms on the left side of the equation
[tex]qa+r^2a=m\\\\a(q+r^2)=m[/tex]
Then we can divide each side by [tex](q+r^2)[/tex] to isolate a
[tex]a(q+r^2)=m\\\\a=\frac{m}{(q+r^2)}[/tex]

Answer:
The Answer is C
Step-by-step explanation:
The typical equation is m= (y-y1)/(x-x1)

the smith family has a 10% off coupon for dinner at their favorite restaurant. Of the bill $42.50 and they wish to leave a 15% tip, what will they pay in total?
Answer:
The answer is 44.625 .
Step-by-step explanation:
Basically, if we have a pretend number line in your head, subtract 10%. Now, you will have -10%. Add 15%, now: you will have 5%. So, do $42.50 x 5%.
How to calculate percentage of a number. Use the percentage formula: P% * X = Y
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
The answer is 44.625 payed in total to their favorite restaurant.

A group of students has conducted an experiment to investigate which enzyme (cellulase or pectinase) or combination of the two enzymes would produce the most apple juice from small chunks of apples. They mixed the specified amount of each enzyme with 50 grams of apple sauce and then filtered the apple juice for 15 minutes into a graduated cylinder. They repeated the control and experimental groups for a total of 5 trials each. The students' results are given below. Table 5. Apple Juice Production Amount of Apple Juice Produced from Apple Sauce (mL) 10 drops of cellulase 5 drops of pectinase+5 drops of cellulase 10 10 drops of 10 drops of water pectinase 12.5 0.71 Mean of 5 trials St. Dev. SEx 95% CI 3.5 0.61 0.50 0.82
Calculate the standard error of the mean (SE) and 95% confidence interval for the control and experimental groups.
Answer:
Explained below.
Step-by-step explanation:
The information provided is:
Mean Standard Deviation
10 drops of water 4 0.61
10 drops of cellulase 3.5 0.50
10 drops of pectinase 12.5 0.71
5 drops of pectinase 10 0.82
+ 5 drops of cellulase
Calculate the standard error of the mean (SE) and 95% confidence interval for the group "10 drops of water" as follows:[tex]SE=\frac{s}{\sqrt{n}}=\frac{0.61}{\sqrt{10}}=0.192899\approx 0.1929[/tex]
[tex]CI=\bar x\pm t_{\alpha/2}\times SE\\\\=4\pm 2.262\times 0.1929\\\\=(3.5636602,\ 4.4363398)\\\\\approx (3.56, 4.44)[/tex]
Calculate the standard error of the mean (SE) and 95% confidence interval for the group "10 drops of cellulase " as follows:[tex]SE=\frac{s}{\sqrt{n}}=\frac{0.50}{\sqrt{10}}=0.1581139\approx 0.1581[/tex]
[tex]CI=\bar x\pm t_{\alpha/2}\times SE\\\\=3.5\pm 2.262\times 0.1581\\\\=(3.1423778,\ 3.8576222)\\\\\approx (3.14, 3.86)[/tex]
Calculate the standard error of the mean (SE) and 95% confidence interval for the group "10 drops of pectinase" as follows:[tex]SE=\frac{s}{\sqrt{n}}=\frac{0.71}{\sqrt{10}}=0.2245217\approx 0.2245[/tex]
[tex]CI=\bar x\pm t_{\alpha/2}\times SE\\\\=12.5\pm 2.262\times 0.2245\\\\=(11.992181,\ 13.007819)\\\\\approx (11.99, 13.01)[/tex]
Calculate the standard error of the mean (SE) and 95% confidence interval for the group "5 drops of pectinase + 5 drops of cellulase" as follows:[tex]SE=\frac{s}{\sqrt{n}}=\frac{0.82}{\sqrt{10}}=0.25930677\approx 0.2593[/tex]
[tex]CI=\bar x\pm t_{\alpha/2}\times SE\\\\=10\pm 2.262\times 0.2593\\\\=(9.4134634,\ 10.5865366)\\\\\approx (9.41, 10.59)[/tex]
The critical value of t is computed using the t-table for 95% confidence level and (n - 1) 9 degrees of freedom.
Let g(x)=x^2+bx+11. The point (-1,8) lies on graph of g. Find value of b.
Answer:
b=4
Step-by-step explanation:
g(x)=x^2+bx+11
When x = -1 g(x) = 8
8 = (-1)^2 +b(-1) +11
8 = 1 -b+11
Combine terms
8 = 12-b
Subtract 12 from each side
8-12 = 12-b-12
-4 = -b
Multiply by -1
4 = b

if it was to be 100 its would have been 10 tens. so since its 192 its, 19 tens with an extra 2.
There are [tex]9[/tex] tens in [tex]192[/tex].
The system or method of writing certain numbers with the help of some rules is called a number system.
Usually, we write numbers in two ways i. e. national and international.
we write these numbers using periods.
example of the national number system is [tex]23, 56, 78, 999[/tex] that it is read as twenty-three crore fifty-six lakhs seventy-eight thousand nine hundred ninety-nine.
example of an international number system is [tex]456,456[/tex] , read as four hundred fifty-six thousand four hundred fifty-six.
On expanding [tex]192[/tex] we get ;
[tex]192 = 100 + 90 + 2[/tex]
which contains 9 at its tens place .
Thus, on expanding we get [tex]9[/tex] tens.

Now, suppose the equation is being represented by y = a+bx
where;
[tex]a = \dfrac{\sum Y * \sum X^2 -\sum X^2 \sum Y}{n * \sum X^2 - (\sum X)^2}[/tex]
[tex]a = \dfrac{1532920 *105168100-30490(52672\times 10^5)}{9 *105168100 - (30490)^2}[/tex]
a = 36588.821
Also,
[tex]b = \dfrac{n \sum XY - \sum X \sum Y}{n \sum X^2 -(\sum X)^2}[/tex]
[tex]b = \dfrac{9* 52672*10^5 -30990*1532920}{9*105168100-(30490)^2}[/tex]
b = 39.476
Thus;
Y = $36588.82 + $39.48X
The predicted cost of radiology for 3500 appointments will be :
Y = $36588.82 + $39.48X
Y = $36588.82 + $39.48(3500)
Y = 174768.82

Answer:

Step-by-step explanation:
x=-1, 2 and -3 are solutions of equation x^3+2x^2-5x-6=0
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is x^3+2x^2-5x-6=0
As we know that 2 is a zero of f(x)
So we need to simplify it by synthetic division as in attached figure.
We get x2+4x+3
x2+3x+1x+3
x(x+3)+(x+3)
(x+1)(x+3)
So as (x-2)=0
x=2
x+3=0
x=-3
x+1=0
x=-1
Hence x=-1, 2 and -3 are solutions of equation x^3+2x^2-5x-6=0

If 5(p + 3) = 18 + 2p, what is the value of p?
Answer:
P=1
Step-by-step explanation:
5(p+3)=18+2p Muiplity p and 3 by 5.
5p+15=18+2p Now you want to have p on one side. You can start by subtracting 15 from both sides.
5p+15=18+2p
-15 -15
5p=3+2p
-2p -2p
3p=3
Now you want to divide it so you can't get a number with P.
3p=3
÷3 ÷3
p=1
You're answer will be p=1.
The value of p in expression 5(p + 3) = 18 + 2p is 1
What is Mathematical function ?
Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.
In other words the function represents the graph between x and y that is for each value of x there exist one value of y but here there is no restriction in values of y that is y can have infinity values.
Given expression is 5(p + 3) = 18 + 2p and to solve for the value of p separate p terms and constant aside and then find p as shown :
5(p + 3) = 18 + 2p
5p+15 = 18 +2p
5p-2p = 18-15
3p = 3
p =3/3
p =1
Therefore, the value of p in expression 5(p + 3) = 18 + 2p is 1.
