Answer:
9/10
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by that fraction's reciprocal (basically the fraction flipped).
[tex]\frac{3}{5}[/tex] ÷ [tex]\frac{2}{3}[/tex] = [tex]\frac{3}{5} *\frac{3}{2} =\frac{3*3}{5*2} =\frac{9}{10}[/tex]
Answer: The normal answer is 0.9! Hope this helps!

Question 2
The vertex form of the equation of a horizontal parabola is given by , x=1/4p(y-k)2+h where (h, k) is the vertex of the parabola and the absolute value of p is the distance from the vertex to the focus, which is also the distance from the vertex to the directrix. You will use GeoGebra to create a horizontal parabola and write the vertex form of its equation. Open GeoGebra, and complete each step below.
Part A
Mark the focus of the parabola you are going to create at F(-5, 2). Draw a vertical line that is 8 units to the right of the focus. This line will be the directrix of your parabola. What is the equation of the line?
Part B
Construct the line that is perpendicular to the directrix and passes through the focus. This line will be the axis of symmetry of the parabola. What are the coordinates of the point of intersection, A, of the axis of symmetry and the directrix of the parabola?
Part C
Explain how you can locate the vertex, V, of the parabola with the given focus and directrix. Write the coordinates of the vertex.
Part D
Which way will the parabola open? Explain.
Part E
How can you find the value of p? Is the value of p for your parabola positive or negative? Explain.
Part F
What is the value of p for your parabola?
Part G
Based on your responses to parts C and E above, write the equation of the parabola in vertex form. Show your work.
Part H
Construct the parabola using the parabola tool in GeoGebra. Take a screenshot of your work, save it, and insert the image below.
Part I
Once you have constructed the parabola, use GeoGebra to display its equation. In the space below, rearrange the equation of the parabola shown in GeoGebra, and check whether it matches the equation in the vertex form that you wrote in part G. Show your work.
Part J
To practice writing the equations of horizontal parabolas, write the equations of these two parabolas in vertex form:
focus at (4, 3), and directrix x = 2
focus at (2, -1), and directrix x = 8
equation is below...

In a lab experiment, 2000 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 23 hours. How many bacteria would there be after 26 hours, to the nearest whole number?
Answer:
4,261
Step-by-step explanation:
after 23 hours, the number of bacteria =
4,000.
so, after 26 hours = 4,000+ (3/23 ×4000)
= 4,000 + 261 = 4,261

3 + 6x = 15?
pls help :D
Answer:
x = 2
Step-by-step explanation:
3 + 6x = 15
rearrange to 6x + 3 = 15
subtract 3 to both sides 3 - 3 and 15 - 3
simplify 6x = 12
x = 2

Two trains, Train A and Train B, weigh a total of 243 tons. Train A is heavier than Train B. The difference of their weights is 87 tons. What is the weight of each train?
Answer:
Train A weighs 156 tons, and Train B weighs 78 tons.
Step-by-step explanation:
Given that two trains, Train A and Train B, weigh a total of 243 tons, and Train A is heavier than Train B, with a difference of their weights of 87 tons, to determine what is the weight of each train, the following calculation has to be done:
(243 - 87) / 2 = B
156/2 = B
78 = B
243 - 87 = A
156 = A
Therefore, Train A weighs 156 tons, and Train B weighs 78 tons.

1. What is the perimeter of the triangle below? Show your work.
Answer:
16.73 I THINK
Step-by-step explanation:
my guess is n1 is relating to the 4.9, and if it then you would do the Pythagorean theorem. because the degrees are there to let you know it's a right angle and you are able to use the theorem..... so -
4.9^2 + 4.9^2 =C^2
48.02 =C
√48 = 6.93 (rounded to nearest hundredth)
then you add them all together
4.9+4.9+6.93=16.73

3/2 of a number is less than this number?
true or false, justify your answers
Answer:
False because 1/2 would be half the number 2/2 or 1 would be the whole number so 3/2 would be a whole and half or 1 1/2
Answer:
false
if the number is X
3/2 of X= X 1/2

Estimate the slope of the regression line manufacturer of cases for sound equipment requires drilling holes for metal screws. The drill bits wear out and must be replaced; there is expense not only in the cost of the bits but also for lost production. Engineers varied the rotation speed of the drill and measured the lifetime in thousands of holes drilled of bits at different speeds in surface feet per minute (sfm). Suppose you want to create a model that estimates the drill bit lifetime ( y) based on rotation speed ( x). Summary statistics for 20 observations collected are given below.

i= 1 i=1 i=1 i=1
Estimate the slope of the regression line.
a. -0.017
b.-0.037
c. -0.057
d.-0.077
Answer:
[tex]b_i = -0.020125[/tex]
Step-by-step explanation:
Given
[tex]\sum x_i= 2000[/tex]
[tex]\sum y_i= 86.6[/tex]
[tex]\sum x_i^2= 216000[/tex]
[tex]\sum x_iy_i = 8338[/tex]
[tex]n = 20[/tex]
Required
Determine the slope (b) of the regression line
This is calculated as:
[tex]b_i = \frac{\sum xy - \frac{\sum x\sum y}{n}}{\sum x^2 - \frac{(\sum x)^2}{n}}[/tex]
Substitute values for each term, we have:
[tex]b_i = \frac{8338 - \frac{2000 * 86.6}{20}}{216000 - \frac{(2000)^2}{20}}[/tex]
Simplify the numerator
[tex]b_i = \frac{8338 - 8660}{216000 - \frac{(2000)^2}{20}}[/tex]
Simplify the denominator
[tex]b_i = \frac{8338 - 8660}{216000 - 200000}[/tex]
[tex]b_i = \frac{-322}{16000}[/tex]
[tex]b_i = -0.020125[/tex]
Find the Find the marginal cost function, given the average cost function AC=100100Q+2arginal cost function, given the average cost function AC=100100Q+2
Answer:
Step-by-step explanation:
a) total fixed cost is 100(derived from total cost function). It is not depended on output.
b)AFC=TFC/Q.AFC=TFC/Q.
AFC(100)=100/100=1.AFC(100)=100/100=1.
AFC(300)= 100/300=1/3.AFC(300)=100/300=1/3

If you know that R' (20)=50 and R''(20)=-4, approximate R'(24)
Approximate R' by using a linear approximation: for x close enough to 24, you have
R'(x) ≈ L(x) = R' (20) + R'' (20) (x - 20)
Then
R' (24) ≈ R' (20) + R'' (20) (24 - 20) = -4 + 50 (24 - 20) = 196
You have the following expenses. What should your estimated monthly expenses be?
Expense type: Cost:
mortgage (monthly) - $1,045.87
groceries (bi-weekly) - $165.00
telephone (monthly) - $62.48
car payment (monthly)-$328.79
A.) $1,698.00
B.) $1,760.00
C.) $1,768.00
D.) $1,602.00
Answer:
Total monthly cost= $1,767.14
Option C.
Step-by-step explanation:
Giving the following information:
Expense type: Cost:
mortgage (monthly) - $1,045.87
groceries (bi-weekly) - $165.00
telephone (monthly) - $62.48
car payment (monthly)-$328.79
We need to sum the monthly expenses and duplicate the grocery costs because are bi-weekly.
Total monthly cost= 1,045.87 + 165*2 + 62.48 + 328.79
Total monthly cost= $1,767.14
