Explanation:
Here is one way to go about it.
Statement . . . . Reason
1. AD ≅ BC, AD║BC, E & F are midpoints of BC, AD . . . . given
2. (1/2)AD ≅ (1/2)BC . . . . multiplicative property of congruence (equality)
3. DF = (1/2)AD, BE = (1/2)BC . . . . definition of midpoint
4. DF ≅ BE . . . . substitution property of congruence
5. BE║DF . . . . segments of parallel lines are parallel
6. BEDF is a parallelogram . . . . BE ≅ DF, BE║DF, definition of parallelogram
Can anyone please help with this?
Answer:
see explanation
Step-by-step explanation:
Find AC
AC = AD + DC = 3y + 4x
(i)
AE = [tex]\frac{1}{2}[/tex] AC = [tex]\frac{1}{2}[/tex](3y + 4x) = [tex]\frac{3}{2}[/tex] y + 2x
(ii)
CB = - AD = - 3y
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

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.

(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]

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.

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
