Answer:

  9 miles

Step-by-step explanation:

Of course, 45 min = 45/60 hours = 3/4 hours.

__

The relationship between time, speed, and distance is ...

  distance = speed · time

  distance = (12 mi/h) · (3/4 h) = 9 mi

Her position will be 9 miles from 0 after 3/4 hour.

Answer:

x=67.5ft

Step-by-step explanation:

similarity and congruence

the length of one side of the bigger triangle divided by the length of the similar side of the smaller triangle

equate the unknown ratio with a known ratio

71.5/49.5=97.5/x

x=(97.5 x 49.5)/71.5

x=67.5 ft

Step-by-step explanation:

PEMDAS:

16 ÷ 2 + 6(8 - 2^2 )

2^2 = 4

(8-4) = 4

16 ÷ 2 + 6(4)

16 ÷ 2 + 24

8 + 24

32

Answer:

3

Step-by-step explanation:

In expressions, there are 4 items to look at :

1. Terms

2. Coefficients

3. Like Terms

4. Constant Terms

Since 4. is the topic at hand, let's focus on that, constant terms are terms that cannot be changed value.

This would mean numbers without a variable, look at the expression below :

7x + 3

Since 3 doesn't have a variable, therefore 3 is a constant term.

Answer:

C. 7

Step-by-step explanation:

The graph that is drawn here shows the altitude as a function of time. When the plane takes off from Chicago, the graph will start from the horizontal axis.

Next, when the plane takes 3 intermediate stops, altitude will touch the horizontal axis 3 times.

Next, when the plane lands in New York the altitude will touch the horizontal axis.

Next, when plane takes off from New York and takes an intermediate stop, altitude will touch horizontal axis.

Lastly the altitude will touch the axis when plane lands back in Chicago.  

So, cumulatively the altitude will touch the horizontal axis seven times.

Answer:

please check explanations

Step-by-step explanation:

As we all know, i is same as root of -1

let us expand what we have;

(1 + i)^2

= 1(1 + i) + i(1 + i)

= 1 + i + i + i^2

as i is square root of -1, the square of the square root of -1 is -1

Thus, we have

1 + 2i - 1

= 2i

Derivatives

The definition of a derivative is the slope of the tangent line.

Limit Definition of a Derivative: [tex]\displaystyle f'(x)= \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}[/tex]  

Step-by-step explanation:

Step 1: Define

f(x) = 7x² + 7x + 3

Slope of tangent line at x = 4

Step 2: Differentiate

Step 3: Find Slope

This means that the slope of the tangent line at x = 4 is equal to 63.

8 and 1 are alternate exterior angles.

Answer:

<8 and <1

Step-by-step explanation:

<8 and <1 are both outside of the parallel so they are exterior and opposite to each other which is alternative exterior.

Hope this helps, thank you !!

The answer is A. 2 and 4

Reason:

To formula for circumference is 2 x r x pi

2 x 2 = 4, 2 x 4 = 8and 4 + 8 = 12

Area is r ^2 x pi

2 ^2 = 4, 4^2 = 16 and 4 + 16 = 20

Answer:

A. (3x+2)(3x+2)

Answer:

The answer is D

Step-by-step explanation:

The expression that shows the total amount the two schools raise is 7x + 8y + 90.

It should be noted that an expression is simply used to show the relationship between the variables that are used.

From the information, the expression 7x +60 represents the amount Oak Middle School raises and the expression 8y + 30 represents the amount Lake Middle School raises.

Therefore, the total amount will be:

= 7x + 60 + 8y + 30

= 7x + 8y + 90

The total amount is 7x + 8y + 90.

The formula for slope is vertical change ÷ horizontal change, which means choose two points, (x1,y1) and (x2,y2), then do (y2-y1) ÷ (x2-x1).

For the graph, just pick two random points that you like. For the table, pick two sets of numbers (for example -10,-47 and 4,9). For the equation, create two sets of coordinates. For example, if you have f(x) = x + 3, then if x = 1, y = 4 and if x = 2, y = 5.
