Answer:

H = 15 + M

Step-by-step explanation:

The plant starts out at 15 cm tall, therefore the y intercept is (0,15) and there is an x intercept but it isn't valid in this case as a plant cannot grow backwards (I assume). The domain would be (0,infinity) and the range would be (15,infinity).

Answer/Step-by-step explanation:

The answer choices to this question showing possible set of data that could be represented by the box plot is missing.

However, here's how to find out which data set could be represented by the box plot.

The box plot given displays of a five-number summary consisting of,

1. The minimum value = 24

2. The second quartile = 27

3. The median value = 31

4. The third quartile = 33

5. The maximum value = 34

With these values known, you can easily find out which data set the box plot represents. Thus, the data set that has a min value of 24, max value of 34, and a median of 31 should be the data set that the box plot is representing. If you have more than one options having these same three values, then proceed to find the second and third quarter to determine which one is the most appropriate.

Answer:

The question is not complete. I will explain relative extrema and how to calculate it.

Step-by-step explanation:

The singular of extrema is extremum and it is simply used to describe a value that is a minimum or a maximum of all function values.

A function will have relative extrema (relative maximum or relative minimum) at points in which it changes from decreasing to increasing, or vice versa.

So if f(y) is a function of y

if there exists an interval (a, b) containing d

such that for all y in (a, b) , f(y) ≤ f(d)

if there exists an interval (a, b) containing d

such that for all y in (a, b) , f(y) ≥ f(d)

Kindly note that If f(d) is a relative extrema of f(y), then the relative extrema occurs at y = d.

For the local extrema of a critical point to be determined, the function must go from increasing, that means positive  [tex]f^{'}[/tex], to decreasing, that means negative [tex]f^{'}[/tex], or vice versa, around that point.

[tex]f^{'}[/tex] is determined by finding the first derivative of the function f(y). The relative extrema will therefore allows us to check for any sign changes of f′ around the function's critical points.

Answer:

$61

Step-by-step explanation:

Given

Number of days, x = 5

Expenditure per day, E'(x) = 10x + 11

Required

Determine the expenditure per day (E'(x))

From the question, we have that

[tex]E'(x) = 10x + 11[/tex]

Substitute 5 for x

[tex]E'(5) = 10 * 5 + 11[/tex]

[tex]E'(5) = 50 + 11[/tex]

[tex]E'(5) = 61[/tex]

Hence, the expenditure for 5 days is $61

The cost of completing the job in 5 days will be 61 hundred dollars.

Given information:

A company has found that its expenditure rate per day (in hundreds of dollars) on a certain type of job is given by [tex]E'(x) = 10x + 11[/tex], where x is the number of days since the start of the job.

Now, the job is done for 5 days.

So, the expenditure if the job takes 5 days can be calculated as,

[tex]E'(x) = 10x + 11\\E'(5) = 10\times 5 + 11\\E'(5)=50+11\\E'(5)=61[/tex]

Therefore, the cost of completing the job in 5 days will be 61 hundred dollars.

Answer:

The critical value of chi-square for 20 degrees of freedom and 0.01 level of significance is 37.57.

Step-by-step explanation:

We have to find the value of chi-square for 20 degrees of freedom an area of 0.01 in the right tail of the chi-square.

As we know that in the chi-square table; there is one vertical column represented by 'P' (the level of significance and one horizontal column represented by '[tex]\nu[/tex]' which is degrees of freedom.

Here, the degrees of freedom given to us is 20.

and the level of significance is 0.01 or 1% for the right tail of chi-square.

By looking at the chi-square table, the critical value of chi-square for 20 degrees of freedom and 0.01 level of significance is 37.57.

Answer:

s = 17

Step-by-step explanation:

17 = 4(s - 14) - (-5)

distribute the 4

17 = 4s - 56 - (-5)

combine like terms

17 = 4s - 56 + 5

17 = 4s - 51

add 51 to both sides

68 = 4s

divide by 4

68/4 = 17

Step-by-step explanation:

formula for volume of sphere: V=(4/3)πr³

V=(4/3)πr³

V=(4/3)(3.14)(3)³

V=(4/3)(3.14)(27)

V=113 in³

Answer:

C. Not given

V≈ 113 in³

Step-by-step explanation:

The volume of a sphere can be found using the following formula.

[tex]V= \frac{4}{3} \pi r^3[/tex]

We know the radius is 3 inches and we are using 3.14 for pi. Therefore, we can substitute [tex]3 in[/tex] in for [tex]r[/tex] and [tex]3.14[/tex] in for [tex]\pi[/tex]

[tex]V= \frac{4}{3} *3.14* (3 in)^3[/tex]

Evaluate the exponent first.

(3 in)³=  3 in * 3 in * 3 in = 9 in² * 3 in = 27 in³

[tex]V= \frac{4}{3} *3.14* 27 in^3[/tex]

Multiply 3.14 and 27 in³

[tex]V= \frac{4}{3} * 84.78 in^3[/tex]

Multiply 4/3 and 84.78 in³

[tex]V= 113.04 in^3[/tex]

Round to the nearest cubic inch. The 0 in the tenth place tells us to leave the 113 as is.

[tex]V= \approx 113 in^3[/tex]

Since 113 cubic inches is not an answer choice given, the correct answer is C. not given

Answer:

A. This polynomial could be factored by finding the GCF, then by grouping or using the perfect squares method.

Step-by-step explanation:

2x^3 + 4x^2 + 2x

First factor out the GCF

2x ( x^2 + 2x +1)

Then factor the inside by either using grouping or recognizing that this is a perfect square  a^2 + 2ab + b^2 = ( a+b) ^2

2x ( x^2 + 2 * x * 1 + 1^2)

2x ( x+1) ^2

Answer:

A. This polynomial could be factored by finding the GCF, then by grouping or using the perfect squares method.

Step-by-step explanation:

2x^3+4x^2+2x

factor common term 2x

= 2x (x² + 2x + 1)

then factor x² + 2x + 1 to (x + 1)(x + 1)

= 2x (x + 1)(x + 1)

refining the equation

= 2x (x + 1)²

Variation Constant: k = 7/6

y = 245/6 when x = 7 and z = 5

====================================

Explanation:

"y varies jointly as x and z" means that y = kxz

We have (x,y,z) = (4,14,3) as one triple, so,

y = kxz

14 = k*4*3

14 = 12k

12k = 14

k = 14/12

k = 7/6 is the variation constant

The equation goes from y = kxz to y = (7/6)xz

----------------

Plug in x = 7 and z = 5 to find y

y = (7/6)xz

y = (7/6)*7*5

y = (7/6)*(7/1)*(5/1)

y = (7*7*5)/(6*1*1)

y = 245/6

Answer:

c is write answer.......

Answer:

A = 50 + 0.02x

Step-by-step explanation:

Let the fixed amount be m

Let the charge for each cubic ft used be c

Let the amount of cubic ft of water used be x.

Let the total cost per month be A

Now, for the first household, they used 1500 cubic feet in a month and were billed $80.

This means, x = 1500 ft³ and A = $80

Since, we are told they are charged a fixed amount plus a fee per cubic ft consumed. We can say that;

m + cx = A

Thus,

m + 1500c = 80 - - - - (eq1)

For 2nd household:

They used 2100 cubic feet was billed $92.

Thus;

m + 2100c = 92 - - - - (eq 2)

Let's subtract eq1 from eq 2 to get;

2100c - 1500c = 92 - 80

600c = 12

c = 12/600

c = 0.02

Putting 0.02 for C in eq1 gives;

m + 1500(0.02) = 80

m + 30 = 80

m = 80 - 30

m = 50

From m + cx = A, we can say that;

50 + 0.02x = A
