This graph shows the altitude of a helicopter over time.



What is the slope of the line and what does it mean in this situation?


The slope is –2000 . This means that the helicopter descends 2000 ft each minute.

The slope is –400 . This means that the helicopter descends 400 ft each minute.

The slope is 400. This means that the helicopter ascends 400 ft each minute.

The slope is 2000. This means that the helicopter ascends 2000 ft each minute.

Answer:

the answer is 30% hope this helps you

Answer:

30%

Step-by-step explanation:

The two outcomes (can work the problem and can't work the problem) are complementary.

In probability theory, the complement of any event A is the event [not A], i.e. the event that A does not occur. The event A and its complement [not A] are mutually exclusive and exhaustive.

Complementary events are two outcomes of an event that are the only two possible outcomes.

Complementary outcomes add to 1 or 100%.

100 - 70 = 30.

Answer:

yes he will

Step-by-step explanation:

Hence, if his parents giving him $[tex]35[/tex] per week then he can purchase his game system.

What is the simplification?

Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

Here given that,

Joe has $[tex]180[/tex] in his bank account he wants to buy a new gaming system for $[tex]250[/tex] in two weeks his parents have offered to lend him money if he needs it he gets $[tex]20[/tex] a week for a allowance

So,

His account saving is $[tex]180[/tex].

He wants to purchase a game system which costs $[tex]250[/tex].

His parents giving $[tex]20[/tex] per week. So iin two weeks it is [tex]20(2)=40[/tex]$.

Then , the total savings he had [tex]180+40=220[/tex]$

So he needs [tex]30[/tex]$ more to purchas his game system

If his parents giving him $[tex]35[/tex] per week then in two weeks it would be [tex]35(2)=70[/tex]$.

Then his total savings are

[tex]180+70=250[/tex]$.

Hence, if his parents giving him $[tex]35[/tex] per week then he can purchase his game system.

Answer:

[tex]\frac{38}{45}[/tex]

Step-by-step explanation:

[tex]\frac{4}{10} +\frac{4}{9}[/tex]

So first you need to have a common denominator (the number on the bottom)

The least common denominator (LCD) would be 90.

So then the fractions would be: [tex]\frac{36}{90} +\frac{40}{90}[/tex].

Add.

You get: [tex]\frac{76}{90}[/tex]

Simplify and the answer is [tex]\frac{38}{45}[/tex]

Answer:

Step-by-step explanation:

Step-by-step explanation:

the derivative of an inverse function is

1/f'(f^-1(x))

f'(x) = -6x²

f^-1(7) is solving the original function equation for x under the knowledge that y = 7

7 = 5 - 2x³

2 = -2x³

-1 = x³

=>

x = -1

f'(-1) = -6×(-1)² = -6×1 = -6

so,

(f^-1)'(7) = -1/6

Answer:

4.140393356

Step-by-step explanation:

Mean = (3+4+5+7+10+12+15) / 7 = 8

Count = 7 numbers

Sum of the numbers = 56

Each number minus the mean =

(3-8=-5)(4-8=-4)(5-8=-3)(7-8=-1)(10-8=2)(12-8=4)(15-8=7)

Now square of each of these numbers:

25+16+9+1+4+16+49 = 120

Variance = 120/7 = 17.14285714

Standard deviation = square root of the variance

Sqrt 17.14285714 = 4.140393356

Step-by-step explanation:

this line goes through the points (0, -3) and (4, 0).

so, the y-axis intercept is at y = -3.

therefore, the equation has to end with "- 3".

the slope (the factor of x in the equation) is the y/x ratio of the changes of y and of x when going from one point to the other :

x changes by 4 positive units (from 0 to 4), and y changes by 3 positive units (from -3 to 0).

so, the slope is 3/4.

and so, the equation is

y = (3/4)x - 3

Answer:

A) 5; B) 32; C) 3; D) 14; E) 1/3

Step-by-step explanation:

Answer:

1. 5

2. 42

3. 3

4. 14

5. 0.3333

Step-by-step explanation:

Third Grade:

8 x 5 = 40

8 + 42 = 40

21 ÷ 7 = 3

21 - 14 = 7

---------------------------21 • x = 7

Which can be written as:

21x = 7

To solve the equation above, we need to remove the 21 on the left side to make the x alone. To do that, we divide both sides by 21.

21x/21 = 7/21

21x/21 is x and 7/21 is 0.3333 which means our equation will look like this:

x = 0.3333

Thus, the answer to "21 times what equals 7?" is 0.3333.

Answer:

$3875 at 5%

$4125 at 13%

Step-by-step explanation:

Let x = amount invested at 5%.

Let y = amount invested at 13%.

x + y = 8000

0.05x + 0.13y = 730

Solve the first equation for x and sustitute into the second one to solve by the substitution method.

x = 8000 - y

0.05(8000 - y) + 0.13y = 730

400 - 0.05y + 0.13y = 730

0.08y = 330

y = 4125

x = 8000 - 4125

x = 3875

Answer:

$3875 at 5%

$4125 at 13%

Answer

-10

Step-by-step explanation:

-8w-7=9

add 7 to both sides

-8w=16

divide by negative 8 on both sides

w=-2

w-8=-10

On simplifying,

-8w - 7 = 9

-8w = 16

w = -2

then,

= w - 8

= -2 - 8

= -10.

Answer:

the first one is not equivalent, the second one is equivalent.

Step-by-step explanation:

Step-by-step explanation:

the slope of a line is the ratio y/x.

that means when going from one point to the other, how many units is y changing, when x changes a certain number of units.

so, going from one point to the other here, x changes by 30 units (from -12 to +18). and y changes 15 units (from -9 to 6).

therefore, the slope is

15/30 = 1/2

Answer:

600 hives

Step-by-step explanation:

If 30 is 5% of the total number of hives Joshua has, then 5%x20=100%

So, 30x20=100%

      30x20=600
