Answer: 280 graduates per year

Step-by-step explanation:

the rate of change is the change in y (number of graduates) divided by the change in x (year).

So: [tex]\frac{8.9-7.5}{2010-2005} = 0.28[/tex] because this number is in thousands of graduates, multiply by 1000 to get 0.28*1000=280 graduates per year

Answer:

[tex]\frac{1.4}{5}[/tex]

Step-by-step explanation:

We have the coordinates (2005, 7.5) and (2010, 8.9). To find the rate of change we must use the equation [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] which is [tex]\frac{8.9-7.5}{2010-2005}[/tex]. To simplify that further, we get [tex]\frac{1.4}{5}[/tex] therefore the rate of change is 1.4 over 5.

Answer:

1. 501

2. 1258 or 4258 or 9258

Step-by-step explanation:

1. represent number (d3d2d1) in terms of x. let x = 10's digit (dxd) then

d2 = x

d1 = x + 1

d3 = 5(x + 1) = 5x + 5

d3 + d2 + d1 = 6

(5x + 5) + (x) + (x + 1) = 6

7x + 6 = 6

7x = 0

x = 0   SO

d3 = (5x + 5) = 5

d2 = 0

d1 = x + 1 = 1

501

2. d4d3d2d1 and d1 not = d2 not = d3 not = d4, let d3 = x and d2 = y then

d2 = y

d3 = x

d1 = 4x and d1 = y + 3 so 4x = y + 3 or y = 4x - 3

d4 = perfect square (1 or 4 or 9)

any d must be <= 9

d4d3d2d1 = (1 or 4 or 9)(x)(4x - 3))(4x) so x<3 (0,1,2) or d1 fails <= 9

(1,4,9)(0,1,2)((4x - 3 = (1,5))((4x = 0,4,8)

d3 (0,1,2) must be 2 because 0 does not work for d2 and 1 does not work for d1, so this make d1 (4x) = 8 so

(d4)(2)(4x - 3 = 5)(4x = 8) = d4 (1,4,9) and 258 so

1258 or 4258 or 9258

Answer:

-24 degrees F

Step-by-step explanation:

12+7+5

if the temperature kept on dropping, then you would have just added them all up.

Given :

h(x) = 5 - 9x - equation (1)

h(x) = -67 - equation (2)

since, both of them are equal, let's equate :

⇒h(x) = 5 - 9x

⇒h(x) = -67

⇒h(x) = 5 - 9x ........ (Ⅰ)

⇒h(x) = -67 ......... (ⅠⅠ)

⇒5 - 9x = -67

⇒-9x = -67 - 5 (Combining like terms)

⇒-9x = -72 (Since, (-) is common in L.H.S & R.H.S we'll cancel it out & we will get the values positive)

⇒x = 72/9 (Transposing 9 to R.H.S)

⇒x = 8 (Required Answer)

I believe you're asking about the one-sided limit,

[tex]\displaystyle \lim_{x\to-4^-}\frac{|x+4|}{x+4}[/tex]

Recall the definition of absolute value:

• [tex]|x| = x[/tex] if [tex]x\ge0[/tex]

• [tex]|x| = -x[/tex] if [tex]x < 0[/tex]

Since we're approaching -4 from the left, we're effectively focusing on a domain of [tex]x<-4[/tex] or [tex]x+4<0[/tex]. So, by the definition above, we have [tex]|x+4| = -(x+4)[/tex]. Then in the limit, we have

[tex]\displaystyle \lim_{x\to-4^-}\frac{|x+4|}{x+4} = \lim_{x\to-4^-}\frac{-(x+4)}{x+4} = \lim_{x\to-4^-}(-1) = \boxed{-1}[/tex]

Answer:

(5, -3)

Step-by-step explanation:

let (x1, y1) = (6, -7) and (x2, y2) = (4,1)

(Xmidpoint, Ymidpoint) = ( (x1+x2) / 2, (y1+y2) / 2)

                                       = (5, -3)

The inequality is ;

Total amount to spend = $1900

Bus charge = $175

Admission fee per student = $6.50

Lunch fee per student = $2.25

Number of students = s

Writing out the total cost :

Bus charge + (admission fee × s) + (lunch fee × s) ≤ 1900

175 + 6.50s + 2.25s ≤ 1900

Using the equation defined, we can find s ;

175 + 6.50s + 2.25s ≤ 1900

Solve for s

8.75s ≤ 1900 - 175

8.75s ≤ 1725

s ≤ 1725 / 8.75

s ≤ 197.14

The number of students she can bring along is 197 and still stay within her budget.

The series' value is maximized if the sum only consists of positive terms. Notice that each term in the sum takes the form 4n + 1 for integer n. This means the smallest positive integer that the sum can involve is 1, so the maximum value is

S = 29 + 25 + 21 + … + 9 + 5 + 1

Reversing the order of terms gives the same sum,

S = 1 + 5 + 9 + … + 21 + 25 + 29

Adding terms in the same positions gives us twice this sum,

2S = (29 + 1) + (25 + 5) + (21 + 9) + … + (1 + 29)

Notice how each grouped sum adds to 30. There are 8 terms in the sum, since 4n + 1 = 29 when n = 8. So

2S = 8 × 30 = 240   ===>   S = 120

Answer:

The Answer is 29cm

Step-by-step explanation:

The area of this shape is made from two shapes.

Shape one is a rectangle with the dimensions 2cm by 4cm

2x4 = 8

So the area of rectangle 1 is 8

The other rectangle has the dimensions 4cm by 7cm

Because you have to account for the other triangle not being there (solved)

4x7 = 21

21+8

29cm

Answer: I think it’s C

Step-by-step explanation:

Hello there!

We've already given the formula so I will not be adding it here.

We are also given that π = 3 for this problem.

r is defined as 'radius'

Radius is a point from center to one of endpoints.

Look at the image, the radius is given as 7cm.

From the information we gathered:

Substitute in the formula.

[tex] \displaystyle \large{ V = \frac{4}{3} (3) {(7)}^{3} }[/tex]

Cancel 3 out.

[tex] \displaystyle \large{ V = 4{(7)}^{3} }[/tex]

Evaluate 7^3

[tex] \displaystyle \large{ V = 4(343) }[/tex]

Multiply

[tex] \displaystyle \large{ V = 1372 }[/tex]

Therefore, the volume is 1372.

Let me know if you have any questions!

Topic: Surface Area and Volume - Sphere's Volume

Step-by-step explanation:

what's the problem ? your teacher even gave you the formula for the volume of a sphere and allowed you to round pi to simply 3. and he gave you the radius directly (not even "hidden" as diameter).

so, what is it you cannot do by yourself ? if you are unsure about doing these calculations in your head, use a calculator.

this is all much, much faster than uploading such a question here and waiting for a response, which very often will just be nonsense, because some people here just only make fun of such simple questions.

r = 7

pi = 3

so,

V = 4/3 × 3 × 7³ = 4 × 7³ = 4 × 343 = 1372 cm³

that's it.

please, when you have the time let me know, where the problem was, and if I can help you better understanding this problem.

Answer:

Step-by-step explanation:

to find the inverse of an equation

1. substitute x=y and y=x

y = (x-3)³ is the initial equation

x= (y-3)³

2. write the new equation as y= something

∛x= ∛(y-3)³, cube root both sides

∛x = y-3 , add 3 to both sides

y = ∛x +3

the inverse equation of y = (x-3)³ is y = ∛x +3

Answer:

Step-by-step explanation:

You're looking for where f(1) exists, not the limit as x approaches 1. So where f(1) exists is where the dark point is, not where the hole is. Therefore, f(1) = -6.
