Airplanes use radar (radio waves) to measure distances.
The plane is at a height of 5200 m. The airport is 10.2 km away.
How far does the plane need to travel before it lands?
a) 11.4 km
b) 10.4 km
c) 5200 km
d) 10.2 km
Answer:
10.2 km
Step-by-step explanation:
I thought we have to add 5200 m + 10,2 km, but for this result there is no an alternative. So the correct answer must be 10,2 km, if the plane is right above the airport.

A fan has five equally spaced blades. Suppose you line up two fans directly on top of each other. What is the least number of degrees that you can rotate the top fan so that the two fans are perfectly aligned again?
A fan has 5 equally spaced blades.
A. 120°
B. 60°
C. 90°
D. 72°
Find mAPD .
60
Select one:
O a. 30 degrees
O b. 60 degrees
O c. 45 degrees
O d. 90 degrees
Answer:
I believe it's a because 90 + 60 would get you 150 and then you add 30 and it gives you 180/half a circle

Describe the differences between the graphs, tables, equations, and verbal descriptions of the Linear and Nonlinear functions.
Answer: 1. The graph of a linear function shows a constant rate of change. A nonlinear function does not have a constant rate of change. So, its graph is not a line. Does the table represent a linear or nonlinear function?While all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x-value to only one y-value). ... is a linear equation but does not describe a function. 2. An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in maths when you do not know the exact number in a calculation. 3. As we stated earlier, nonlinear functions are functions that are not linear functions. Therefore, they have the opposite properties of a linear function. The graph of a linear function is a line. Thus, the graph of a nonlinear function is not a line.

Look at this triangle.
B
8 cm
A
22 cm
Work out length AB.
Answer:
23.41cm
Step-by-step explanation:
Using Pythagoras theorem
a²+b² = c²
Where a and b are sides of the triangle and c is the Hypotenuse.
If we substitute the values
B= 8 cm
A= 22 cm
22²+8² = c²
484 + 64= c²
√548 = c
C= 23.41
Hence, length AB is 23.41cm

A convenience store sells two brands of orange juice. Brand A contains 8 fluid ounces and costs $1.28. Brand B contains 12 fluid ounces and costs $1.68. What is the difference in cost, in dollars, per fluid ounce between the two brands?
Answer:
$0.02
Step-by-step explanation:
Brand a
1.28 ÷ 8 = 0.16 per ounce
Brand b
1.68 ÷ 12 = 0.14 per ounce
0.16 - 0.14 = 0.02

P is inversely proportional to the square of q. When q = 2, P = 12.8 (a) Find a formula for P in terms of q.
Answer:
P = 51.2/ q
Step-by-step explanation:
Given :
P α 1/q²
P = k/q²
k = constant of proportionality
P = 12.8 ; q = 2
12.8 = k /2²
12.8 = k / 4
k = 12.8 * 4
k = 51.2
Formuka for P in terms of q :
P = 51.2/ q
(hi can someone help me with this?) If f(x) = 4x - 3, what is f(x)^-1?
a.) x/4 + 3
b.) x + 3/ 4
c.) 3 - 4x
d.) 4/x+3
Answer:
F(x) ^-1= x+3/4
Step-by-step explanation:
Exchange f(x) for y
Y=4x-3
+3
Y+3=4x
/4
Y+3/4=x
Swap y and x
F(x)^-1= x+3/4

Answer:
f(x) = -2(x-3)^2+8
Step-by-step explanation:
Using vertex form: f(x)= a(x-h)^2 +k
if the maximum is 8 then k=8
h = 3 --> the midpoint of 1 and 5
Fill in the equation:
f(x) = a(x-3)^2 +8
Using f(1) = 0 to figure out a:
0 = a(1-3)^2+8
4a =-8
a = -2
Our final equation would be[tex]f(x)=-2(x-3)^2+8[/tex]
In standard form: [tex]f(x)=-2x+12x-10[/tex]
Write an equation in slope intercept form for the line with slope 2/5 and y- intercept -1
Answer:
y =(2/5)x - 1
Step-by-step explanation:
Slope intercept form: y = mx + b
m is slope and b is y-intercept
y =(2/5)x - 1
Answer: y = 2/5x - 1
Step-by-step explanation:
b = y1 - m • x1
-1 = -1 -(2/5) • (0)
= -1
y = mx + b
y = 2/5x - 1

Does association between variables mean that there is a cause-and-effect
relationship? Why or why not? Give an example.
Answer:
Yes
Step-by-step explanation:
Two variables may be associated without a causal relationship. For example, there is a statistical association between the number of people who drowned by falling into a pool and the number of films Nicolas Cage appeared in in a given year. However, there is obviously no causal relationship.
