Answer:
A) The first function (the quadratic one) is growing more rapidly.
B) Between x=0 and x=1.
C) We can assume that they don't intersect again.
Step-by-step explanation:
A)
The first function (the quadratic one) is growing more rapidly. We can see this because the difference between its y values is so much greater than the difference between the y values for the exponential function.
B)
Between x=0 and x=1. When functions intersect, their y and x values are equal. The y-values are equal at some point over x=0 and x=1 because they both cross over the same range (y=1 and y=2)
C)
We can assume that they don't intersect again because the y-values for the exponential equation will never reach the corresponding values for the quadratic equation; it simply isn't growing rapidly enough.

answer:
shape f !
step-by-step explanation:
hi there!
the question is asking us which shape matches shape a right, now if we look closely we already know that shapes d and b look like they match each other rather then shape a
shape a - 2, 2, 4
so they are out of the equation ( checking how long the sides are )
shape d - 3, 3, 3
shape b - 3, 3, 3
shapes e and c look like they match each other but just to make sure, i counted how long the each side was for both of them
( going by blocks )
shape c - 2, 3, 4,
shape e - 2, 3, almost 5
which does leave us left with shape f, but just to make sure.. lets count it!
shape f - 2, 2, 4,
which is the same numbers that shape a has!
shape f = shape a
hope this helps you!! and if i made a mistake reading the problem or doing the problem then please tell me :) have a good day
I need help again

Step-by-step explanation:
A study was conducted to investigate whether there are regional differences in peanut butter preference in the United States. The country was divided into 7 geographic regions, and in each region a random sample of peanut butter eaters were asked whether they preferred creamy or crunchy peanut butter. The responses were summarized in a 7-by-2 table of counts for each combination of geographic region and creamy or crunchy peanut butter preference. Which of the following tests is the most appropriate for the investigation?
Answer:
C- Chi-square test for Homogeneity
Step-by-step explanation:
Because you're looking for whether there are regional differences in peanut butter into 7 different samples, that means you're searching for i categorical variable in the 7 different random samples, making it a chi-square for homogeneity.
Brianna has a 50$ online gift certificate from a book store. The cost of each book is $9. There is also a shipping charge of 5$ for her entire order. How many books can Brianna buy without spending more than her gift certificate amount?
Answer:
5
Step-by-step explanation:
9x+5=50
9x=45
x=5
Brianna can buy up to 5 books without spending more than her gift certificate amount.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
If each book costs $9 and Brianna has a $50 gift certificate, we can start by dividing the total amount she can spend by the cost of each book.
$50 gift certificate / $9 per book = 5.55 books
Since Brianna cannot buy a fractional part of a book, she can only purchase a whole number of books.
Therefore, the maximum number of books she can buy without spending more than her gift certificate amount is 5 books.
Additionally, there is a $5 shipping charge for the entire order, so Brianna should make sure to factor this into her budget.
If Brianna buys 5 books at $9 each, the total cost of the books will be $45. Adding the $5 shipping charge brings the total to $50, which is the exact amount of her gift certificate.
Therefore, Brianna can buy up to 5 books without spending more than her gift certificate amount.

What is the volume of a rectangular crystal with a length (1) of 2.2 cm, a width (w) of 2 cm, and a height
(h) of 1.8 cm?
Answer:
7.92 cm^3
Step-by-step explanation:
To find volume all you have to do is multiply the length, width, and height. The answer would be: l * w * h = 2.2 * 2 * 1.8 = 7.92 cm^3.

Answer:
(assuming the. values are the shaded areas)
area = x^2 + 2x +2
perimeter = 4x + 8
Step-by-step explanation:
you have all the side except the side of the 2 squares at the top.
The squares are 1 unit on each side because the area of the 2 slender rectangles on each side is x.
So the area is x^2 + x + x + 1 + 1
The perimeter is 1+x+1+1+1+x+1+1+1+x+1+x
(starting from the lower left side and walking around the perimeter clockwise)

A car rental company is interested in the amount of time its vehicles are out of operation for repair work. A random sample of 21 cars showed that, over the past year, the numbers of days that each of these cars had been inoperative were as follows: 15, 11, 19, 24, 6, 18, 20, 15, 18, 12, 14, 19, 5, 21, 12, 11, 8, 10, 7, 2, 14 Assuming that the population is normally distributed, construct a 95% confidence interval for the mean number of days that vehicles in the company's fleet are out of operation.
Answer:
(10.891; 15.869)
Step-by-step explanation:
Given the data::
15, 11, 19, 24, 6, 18, 20, 15, 18, 12, 14, 19, 5, 21, 12, 11, 8, 10, 7, 2, 14
The confidence interval is obtained using the relation :
Mean ± margin of error
Margin of Error = Zcritical * s/sqrt(n)
Using a calculator, the mean value of the data and standard deviation above is :
Mean = Σx / n ; n = sample size
Mean, xbar = 281 / 21
Mean = 13.38
Standard deviation , s = sqrt[Σ(X - xbar)²/ n-1]
Standard deviation, s = 5.82
Margin of Error = Zcritical * s/sqrt(n)
Zcritical at 95% confidence level = 1.96
Margin of Error = 1.96 * 5.82/sqrt(21) = 2.489
Confidence interval :
Mean ± margin of error
13.38 ± 2.489
Lower boundary = (13.38 - 2.489) = 10.891
Upper boundary = (13.38 + 2.489) = 15.869

Moira solved a problem on the board. What error did Moira make and how can she correct it?
12x + 10 = 54 - 10x
12x + 10 - 10 = 54 - 10x - 10
12x = 44 - 10x
12x - 10X = 44 - 10x + 10x
2x = 44
X = 22
A- On the left side of the equation, Moira should have subtracted 10x, and on the right side of the equation, Moira should have added 10x.
B- On the left side of the equation, Moira should have added 10x, and on the right side of the equation, Moira should have subtracted 10x.
C- On the left side of the equation, Moira should have added 10x, and on the right side of the equation, Moira should have also added 10x.
D- On the left side of the equation, Moira should have subtracted 10x, and on the right side of the equation, Moira should have also subtracted 10x.
Please I really need it
Answer:
C
Step-by-step explanation:
What you do on one side of the equation, you do to the other. She added 10x on the right side and subtracted 10x on the left when she should have added 10x on both sides.

The diagonals of rhombus MATH intersect at P(4,-5). If the equation of the line that
contains diagonal MT is y = -2x + 3, what is the equation of a line that contains
diagonal AH?
y = 1/2x +5
y = -1/2x-7
y = -2x + 5
y= 1/2x - 7
Answer:
D. y = 1/2x - 7Step-by-step explanation:
The diagonals of a rhombus are perpendicular:
MT ⊥ AHWe have the equation for MT:
y = -2x + 3Perpendicular lines have negative-reciprocal diagonals, therefore AH has slope of 1/2.
Since AH passes through point (4, -5), the equation of the line is:
y - (-5) = 1/2(x - 4)y = 1/2x - 2 - 5y = 1/2x - 7Correct choice is D

(average) number of blood tests the lab did each day?
answer choices :
o 45
o 42
o 39
0 33
Answer:
The answer is 39.
Step-by-step explanation:
The average is the total amount of blood tests divided by the number of days.
Total: 36 + 43 + 29 + 48 = 156 blood tests / 4 days = 39 blood tests per day.

Write the slope-intercept form of the equation of the line.
Answer:
y = x + 2
Step-by-step explanation:
Choose any two points from the graph
(0, 2) ; (-2 , 0)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]= \frac{0-2}{-2-0}\\\\= \frac{-2}{-2}\\\\= 1[/tex]
y - intercept = 2
y = mx + b {m = 1 and b = 2}
y = x + 2
