Answer:
B) 6
Step-by-step explanation:
We need to figure out the value of k in x⁴+kx²+36 -> (x²+a)(x²+b) where a+b=k and ab=36 as a=b. Therefore, k needs to be 6 because 6*6=36 and 6+6=12 given a=b.

Which best describes the relationship between the line that passes through the points (8, 2) and (3, 5) and the line that passes through the points (–3, –7) and (0, –12)?
Answer:
dddddddd\
Step-by-step explanation:
let f={(1,2),(2,3),(5,6),(7,8) evaluate f(2)and f(5)?
Given:
[tex]f=\{(1,2),(2,3),(5,6),(7,8)\}[/tex]
To find:
The values of f(2) and f(5).
Solution:
If an ordered pair [tex](x,y)[/tex] is in the function [tex]f[/tex], then [tex]f(x)=y[/tex].
In the given set of ordered pairs one ordered pair is (2,3). So, by using the above definition, we get
[tex]f(2)=3[/tex]
In the given set of ordered pairs one ordered pair is (5,6). So, by using the above definition, we get
[tex]f(5)=6[/tex]
Therefore, the value of f(2) is 3 and the value of f(5) is 6.

With the radius being 3.5 once you solve it, the area comes out being 38.48 square inches. Hope this helps :D (also can you mark me brainliest)
Tyler has $600 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. He buys a new bicycle for $233.09. He buys 3 bicycle reflectors for $16.38 each and a pair of bike gloves for $29.13. He plans to spend some or all of the money he has left to buy new biking outfits for $52.48 each. Write and solve an inequality which can be used to determine xx, the number of outfits Tyler can purchase while staying within his budget.
Answer:
x ≤ 5.5
Step-by-step explanation:
Amount with Tyler = $600
Cost of new bicycle = $233.09
Cost of 3 bicycle reflectors = $16.38 * 3
= $49.14
Cost of bike gloves = $29.13
Cost of biking outfit = $52.48
Number of biking outfit = x
233.09 + 49.14 + 29.13 + 52.48x ≤ 600
311.36 + 52.48x ≤ 600
52.48x ≤ 600 - 311.36
52.48x ≤ 288.64
x ≤ 288.64/52.48
x ≤ 5.5
Number of biking outfit = x
x ≤ 5.5

A ball is dropped from a height of 20 feet. The ball rebounds to 80% of its previous height. Let n represent
the number of bounces of the ball.
a. h=20(.20)^n
b. h=20(.80)n
c. h=20(.80)^n
d. h=20(1.80)^n
Answer:
[tex]H=20(0.8)^{n}[/tex]
Step-by-step explanation:
So, lets just go over this step by step and make sense of it.
20 clearly must be what we start with, and as you see in your answers, all of them have that as the number you multiply the parethese by.
Its what next that we dont know about.
We know that the ball rebounds 80% of its previous height.
It for sure cannot be a or d because a would mean that it would only rebound 20% of its height, and d would mean that it rebound 180% of its height.
Its now between b and c.
Lets just think about it.
Pull out your calculator or pull it up on your electronic. Multiply 10 by 0.9. This will get you 9. Multiply 9 again by 0.9, and youll get 8.1.
What did we actually do there? We did 10*0.9^2
Pull out your calculator again and try 10* 0.9^2. Youll see that 0.9 squared is 0.81. This times 10 is 8.1, and that is exactly what you got before.
Understanding this, it is clear that we must use an exponent to fidn future values.
In answer b, it shows that you can just multiply by n.
In answer c however, it uses n as an exponent, which is the correct thing to do.
So c is your answer.
The actual formula for this is: [tex]first_.term(change)^t^e^r^m ^[/tex]
The first term in this case is the first height, which is 20. The change is a rebound of 80%(0.8).
The term is just n, but in most problems n is time.

Solve for x:
4 - 2(x - 3) = 24
please help
Answer: X = -7
Step-by-step explanation:
Answer:
x = -7
Step-by-step explanation:
4 - 2(x - 3) = 24
Distribute
4 -2x +6 = 24
Combine like terms
10 -2x = 24
Subtract 10 from each side
10-2x-10 = 24-10
-2x = 14
Divide by -2
-2x/-2 = 14/-2
x = -7

dont answer if you dont have the answer I will report you The graph of a function contains the points (–1, –4), (0, 1), (1, 4). Is the function linear? Explain.
1. The function is linear because the points are not in a straight line.
2. The function is linear because the graph containing the points is not a straight line.
3. The function is linear because the points are in a straight line.
4. The function is not linear because the graph containing the points is not a straight line.
Answer:
The function is linear because the points are not in a straight line.Points that lie along the same line are said to be "collinear" and collinear points must have the same slope between any pair of points.
~ƒöᏝϗʆѻʁᶥąռ¹₃
[tex]\huge\boxed{\underline{\bf \: Answer}}[/tex]
The answer will be option 1 :-
The function is linear because the points are not in a straight line.Well, for a straight line the points formed are known as collinear points & the points given ->( -1, –4), (0, 1), (1, 4) are not collinear as they are not formed in the same line of the graph. Also, graphs have straight lines. From this we can see that none of the other options work. Hence, option 1 is the correct answer (✓).

Find the circumference of a circle with diameter,
d
= 7.18m.
Give your answer rounded to 2 DP.
Answer:
C = 22.56
Step-by-step explanation:
The equation for the circumference of a circle is [tex]C=2\pi r[/tex].
The radius is half the diameter so [tex]r=\frac{7.18}{2}=3.59[/tex]
Plug the radius into the equation.
[tex]C=2*\pi *3.59[/tex]
[tex]C=22.55664[/tex]
Given:
Diameter of circle = 7.18 m
To find:
Circumference of the circle
Steps:
We know that radius is equal to half of the diameter
r = d/2
r = 7.18/2
r = 3.59 m
Now circumference is equal 2πr
Circumference = 2πr
Circumference = 2 × 3.14 × 3.59 (taking pi as 3.14)
Circumference = 6.28 × 3.59
Circumference = 22.5452
Circumference ≈ 22.55 meters
Therefore, the circumference of the circle is approximately 22.55 meters

Question 17 The numbers in the circles go together in a certain way. Find the missing number marked by the question mark: 180, 14 120, 8 A:70 B: 80 C:60 D: Mr Sockman ?, 4 D:40
Answer:
B. 80
Step-by-step explanation:
According To Question, We Have
(180,14) (120,8) (? , 4) (220,18)
it Clearly Visible That ( 180*a+b=14 ) only Possible when we Put a=1/10 & b=-4. Thus, (180*1/10)-4 ⇔ 18-4 = 14Same For All (120*a+b=8)Thus, (120*1/10)-4 ⇔ 120-4 = 8
Now (?*1/10)-4=4 solve it .
Thus, ?*1/10=8⇔?=80 is Our Missing Number .

Twice a number (z) added to 21 is equal to 9 times the number added to 7. What is the number?
Answer:
The number is 2
Step-by-step explanation:
Twice a number (z) = 2*z = 2z
Twice a number (z) added to 21 = 2z + 21
9 times the number added to 7 = 9z + 7
9z + 7 = 2z + 21
Subtract 2z form both sides
9z - 2z + 7 = 21
7z + 7 = 21
Subtract 7 from both sides
7z = 21 - 7
7z = 14
Divide both sides by 7
z = 14/7
z = 2

5,6,9,15,?,40
Answer:
25
Step-by-step explanation:
The pattern is + 1, + 3, + 6,... i.e. + 1, + (1 + 2), + (1 + 2 + 3),...
.'. Missing number = 15 + (1 + 2 + 3 + 4) = 25.
Answer: 25!
Step-by-step explanation:
5, 6, 9, 15, ?, 40
5 + 1 = 6
6 + 1 + 2 = 6 + 3 = 9
9 + 1 + 2 + 3 = 9 + 6 = 15
15 + 1 + 2 + 3 + 4 = 15 + 10 = 25
25 + 1 + 2 + 3 + 4 + 5 = 25 + 15 = 40

The perimeter of a rectangular field is 60 m.
What are three possible measurements
of the field? Use dimensions to the
nearest meter.
Answer:
10m by 20m
12 m by 18 m
14m by 16m
Step-by-step explanation:
The perimeter of a rectangle is
P = 2(l+w)
60 = 2(l+w)
Divide each side by 2
30 = l+w
Let l = 10
Then w = 30 - 10 = 20
Let l = 12 then w = 30 - 12 = 18
Let l = 14 then w = 30 -14 = 16
John works a fortnightly wage of $750.00. If his basic week is 40 hours. what is his: Weekly wage basic rate and basic fortnight??
Answer:
Basic wage rate = $9.375 per hour
Step-by-step explanation:
Given :
Fortnight wage = $750
Basic week, hours worked per week = 40 hours
Weekly basic wage rate :
Fortnight = 2 weeks
Hence, weekly wage = fortnight wage / 2 = 750 /2 = $375
Weekly basic wage rate = $375 / Number of hours worked per week = $375 / 40 = $9.375 per hour
A restaurant distributed 7,000 coupons. Over the next month, 3,290 of the coupons were redeemed. How many coupons were not used?
Answer:
3,710 coupons
Step-by-step explanation:
You have to do 7,000-3,290 to get the answer, as 7,000 is the total number of coupons given, and 3,290 is the amount of coupons that was used.
7,000-3,290=3,710

Find the distance that the points is given on the graph ?
From the graph, the given points are (2,-1) and (4,0). Use the distance between two points formula:
[tex] \large \boxed{ \sqrt{ {(x_2 - x_1)}^{2} + {(y_2 - y_1)}^{2} } }[/tex]
Substitute these points in the formula.
[tex] \large{ \sqrt{ {(2 - 4)}^{2} + {( - 1 - 0)}^{2} } } \\ \large{ \sqrt{ {( - 2)}^{2} + {( - 1)}^{2} } } \\ \large{ \sqrt{4 + 1} \longrightarrow \sqrt{5} }[/tex]
Hence, the distance is √5
Answer
√5
