A scuba diver is positioned at -30 feet. How many feet will she have to rise to change her to -12 feet.

Answer:

Step-by-step explanation:

First you're going to look at how much honey was eaten each day. Which is  1,4,2,3,0,3,2. Then you're going to look at the line and it says "numbers of jars of honey" it goes up to 4. Then you just put the days on jars so i think it should go like this 1 on line 1 4 on line 4 2 on line 2 3 on line 3 (there will be 2 x's on line 2 and 3)

Answer:

Square side=40ft

Semi-circle diameter=39.98ft

Area of court=2276.69 ft^2

Step-by-step explanation:

The square section has a semicircle joined to it and the combined perimeter is 182.8 ft.

-Area of the square section is obtained by subtracting that of the semicircle from the total(only 3 sides of the square is used since one side is attached to the semi-circle)

Hence, the square's sides  has the dimension of 40 ft.

The semi-circle's diameter is calculated as:

Hence, the semi-circle's diameter is 39.98 ft

The area of the court is calculated as:

The court's area is 2,227.69 ft^2

Using exponential function concepts, it is found that the constant 1.0015 reveals that the quantity increases by 0.15% each decade.

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

In this problem, the function is:

[tex]f(t) = 9900(1.0015)^{10t}[/tex]

In which t is the time in decades.

The growth rate is r = 0.0015, as [tex]1 + r = 1.0015 \rightarrow r = 0.0015[/tex], hence the constant 1.0015 reveals that the quantity increases by 0.15% each decade.

Answer:

80 km per liter

Step-by-step explanation:

400 x .20 = 80

Answer: 20

Step-by-step explanation:Distance traveled = 400 km

Petrol used. = 20 liters

Petrol used per km = 400/20

= 20 km

therefore, a car travels 20 km in 1 litre.

a, c and e are equivalent.

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Given

a.  (3.4a – 1.7b) + (2.5a – 3.9b)

b.  (2.5a + 1.6b) + (3.4a + 4b)

c.  (–3.9b + a) + (–1.7b + 4.9a)

d.  (–0.4b) + (6b – 5.9a)

e.  (5.9a – 5.6b)

The addition of the given polynomial.

Add a term with a and b term with b.

a.  (3.4a – 1.7b) + (2.5a – 3.9b)

3.4a - 1.7b + 2.5a -3.9b

5.9a - 5.6b

b.  (2.5a + 1.6b) + (3.4a + 4b)

2.5a + 1.6b + 3.4a + 4b

5.9a + 4.6b

c.  (–3.9b + a) + (–1.7b + 4.9a)

-3.9b + a - 1.7b + 4.9a

5.9a - 5.6b

d.  (–0.4b) + (6b – 5.9a)

-0.4b + 6b - 5.9a

-5.9a + 5.6b

e.  (5.9a – 5.6b)

5.9a - 5.6b

Thus, a, c, and e are equivalent.

Step-by-step explanation:

The left piece is a little tricky because it does not intersect the y-axis. You know it has a slope of -1, so it will be 1 unit higher than the y-intercept when it is 1 unit left of the y-axis. It ends at (-1, 3). The end point is not included in the definition of the relation, so an open circle is shown.

The right piece crosses the y-axis at y=-3, and has a slope of 2. It ends at (-1, -5). This end point is included, so a solid dot will be found at (-1, -5).

The relation is doubly-defined at x = -1, so there is another solid dot at (-1, -2).

Additional comment

It is incorrect to call this a function, because it fails the vertical line test at x = -1. There are two points on that vertical line. (You may want to discuss this question with your teacher.)

Here's the required formula to find the missing side of triangle by pythagoras theorem :

[tex]{\longrightarrow{\pmb{\sf{{(a)}^{2} + {(b)}^{2} = {(c)}^{2}}}}}[/tex]

Substituting all the given values in the formula to find the third side of triangle :
