If p varies inversely as Q2 and p = 4 when Q =0.5, find p when Q = 1.5

Answers

Answer:

a) k = 8

b) p = 12

Step-by-step explanation:

Step(i):-

Given that p varies inversely as Q

                           p∝ Q

                           p = k Q

Given that p = 4 and Q = 0.5

                        4 = k (0.5)

                       k = [tex]\frac{4}{0.5} = 8[/tex]

Step(ii):-

 Given that Q = 1.5

                  p = k Q

                 p = 8 (1.5)

                p = 12

Write the following in slope-intercept form
12x + 10y = 100

Answers

Answer:

I'm learning this too the answer is 12x+10y10

slope-intercept form: y = mx + b

we know what format we need to change the equation to.

subtract 12x to each side to get 10y alone.

12x - 12x + 10y = 100 - 12x

10y = -12x + 100

divide 10 to both sides to get y alone.

10/10y = -12/10x + 100/10

y = -6/5x + 10

y = -6/5x + 10 is your answer. i hope this helpes! let me know if i got something wrong that i need to fix.

what is the inverse of f (x) = −(x+1)^2+4

Answers

Step-by-step explanation:

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables: y=4−(x+1)2 becomes x=4−(y+1)2.

Now, solve the equation x=4−(y+1)2 for y.

calculate the unit rate of change for each linear function using the formula. (4,9) (8,12) (16,18) (32,30)

Answers

Answer:

The unit rate of change is of [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

We are given a set of points (x,y).

To find the unit rate of change, we take two points, and divide the change in y by the change in x.

Points (4,9) and (8,12)

Change in y: 12 - 9 = 3

Change in x: 8 - 4 = 4

Unit rate of change: [tex]\frac{3}{4}[/tex]

Three co-workers recorded the amount of water in a fish tank being replaced at regular intervals.


maggie measured 1/2 gallon of water in 2/3 of an hour.

christine measured 3/4 gallon of water in 6/5 of an hour.

gianna measured 2/3 gallons of water in 4/5 of an hour.


What two statements are true?

A. Giannas fish tank replaced the most water per hour.

B. Christies fish tank replaced the most water per hour.

C. Christies fish tank replaced the least water per hour.

D. All three fish tank replaced more than one gallon of water per hour.

E. Two of the fish tanks almost replaced the same amount of water per hour.

Answers

Answer:

A. Giannas fish tank replaced the most water per hour.

C. Christies fish tank replaced the least water per hour.

Step-by-step explanation:

Let define the replacement rate ([tex]r[/tex]), measured in gallons per hour, by the ratio of capacity ([tex]c[/tex]), measured in gallons, to replacing time ([tex]t[/tex]), measured in hours. That is:

[tex]r = \frac{c}{t}[/tex] (1)

The co-worker with the highest rate replaces the most water in a hour. Let see the rate of each co-worker:

Maggie ([tex]c = \frac{1}{2}\,gal[/tex], [tex]t = \frac{2}{3}\,h[/tex])

[tex]r = \frac{\frac{1}{2}\,gal }{\frac{2}{3}\,h }[/tex]

[tex]r = \frac{3}{4}\,\frac{gal}{h}[/tex]

[tex]r = 0.75\,\frac{gal}{h}[/tex]

Christine ([tex]c = \frac{3}{4}\,gal[/tex], [tex]t = \frac{6}{5}\,h[/tex])

[tex]r = \frac{\frac{3}{4}\,gal }{\frac{6}{5}\,h }[/tex]

[tex]r = \frac{15}{24}\,\frac{gal}{h}[/tex]

[tex]r = \frac{5}{8}\,\frac{gal}{h}[/tex]

[tex]r = 0.625\,\frac{gal}{h}[/tex]

Gianna ([tex]c = \frac{2}{3}\,gal[/tex], [tex]t = \frac{4}{5}\,h[/tex])

[tex]r = \frac{\frac{2}{3}\,gal }{\frac{4}{5}\,h }[/tex]

[tex]r = \frac{10}{12}\,\frac{gal}{h}[/tex]

[tex]r = \frac{5}{6}\,\frac{gal}{h}[/tex]

[tex]r = 0.833\,\frac{gal}{h}[/tex]

From these informations, we conclude that Gianna's fish tank replaced the most water per hour and Christine replaced the least water per hour. All three fish tanks replace less than one gallon of water per hour. Therefore, correct answers are A and C.

2. The route used by a certain motorist in commuting to work contains two intersections with traffic signals. The probability that he must stop at the first signal is 0.36, the analogous probability for the second signal is 0.54, and the probability that he must stop at at least one of the two signals is 0.65. What is the probability that he must stop at exactly one signal?

Answers

Answer:

0.30

Step-by-step explanation:

Probability of stopping at first signal = 0.36 ;

P(stop 1) = P(x) = 0.36

Probability of stopping at second signal = 0.54;

P(stop 2) = P(y) = 0.54

Probability of stopping at atleast one of the two signals:

P(x U y) = 0.6

Stopping at both signals :

P(xny) = p(x) + p(y) - p(xUy)

P(xny) = 0.36 + 0.54 - 0.6

P(xny) = 0.3

Stopping at x but not y

P(x n y') = P(x) - P(xny) = 0.36 - 0.3 = 0.06

Stopping at y but not x

P(y n x') = P(y) - P(xny) = 0.54 - 0.3 = 0.24

Probability of stopping at exactly 1 signal :

P(x n y') or P(y n x') = 0.06 + 0.24 = 0.30

Help I will give Brainily to the one that give me the explanation and answer

Answers

Answer:

Step-by-step explanation:

It is a vertical parabola. The equation of a vertical parabola can be written in the form y = a(x-h)² + k, where a>0 and (h,k) is the vertex.

You can eliminate G and I because the leading coefficient is negative.

The graph isn't marked with units, but both F and H say that the vertex is at (0,-2), so you know that each square on the graph is one unit.

Now look for another clue.

The x-intercepts are at (-1,0) and (1,0). Plug one of the points into F and H.

F: 0 = 2·1² - 2

H: 0 ≠ 1² - 2

So, F represents the graph.

F(x)=3x^2-11 find f(-5)
