Answer:
3.61 sec
Step-by-step explanation:
Set the given d= 3t + 3t ^2 equal to 50 and solve for t:
3t^2 + 3t - 50 = 0
This is a quadratic equation with coefficients 3, 3 and -50. The discriminant is b^2 - 4ac, or 3^2 - 4(3)(-50), or 9 + 600 = 609
The roots of this quadratic are therefore:
-(3) ± √609 -3 ± 24.68 21.68
t = -------------------- = ------------------- = ----------- = 3.61 sec
2(3) 6 6
Use the discriminant to determine the number of real solutions to the quadratic equation. 11m2+12m+4=0 What is the number of real solutions? Select the correct answer below: 0 1 2
Answer:
0
Step-by-step explanation:
The discriminant is
12^2 - 4*11*4 = -32
Since it is negative, there are 0 real solutions

A premier credit card has an initiation fee that provides you with the privilege to use it and a monthly fee after the first two months. The initiation fee is $62 and the monthly fee is $30 per month after the first two months. If C represents the cost and g represents the total number of months, which equation could represent this plan when you have this card for more than two months?
A. C = 30 + 62(g-2)
B. C = 30 + 62(2-g)
C. C = 62 + 30(g-2)
D. C = 62 + 30(2-g)
Answer:
The correct option is C.
Step-by-step explanation:
To have this credit card there is two fees, one that is fixed payed upfront and other that is payed after the second month. The fixed fee costs $62, and doesn't escalate with time, while the other one is $30 and starts to be charged after the second month. Therefore, the total cost of the card is the fixed fee plus the monthly fee multiplied by the number of months the user had the card subtracted by two, or as shown below:
[tex]C(g) = 62 + 30*(g-2)[/tex]
The correct option is C.

Answer:
Step-by-step explanation:
1). Segment AB = [tex]\overline{AB}[/tex] (Option D)
Segments are represented by an over-line/bar on the segment.
2). Length of segment AB = AB (Option B)
3). MN = 7 (Option C)
Since the measure of segments MN and KL are equal from the figure attached.
4). [tex]\overline{KL}[/tex] is congruent to [tex]\overline{MN}[/tex]
Given in the figure attached.
Answer:

The five triangle congruence are sss, sas, aas, asa and hl criteria. Fully explain why aaa is not a triangle congruence criteria
Answer:
As you may know, the addition of all the interior angles of a triangle always adds up to 180°.
So if we know two angles of the triangle, A1, and A2, we can find the third angle as:
A1 + A2 + X = 180°
X = 180° - A1 - A2.
Se with only knowing two angles, we can find the third angle.
So aaa is a criteria equivalent to aa.
Now, the problem with this criteria is that also works for finding similar triangles (for example, an equilateral triangle of sides 10 and an equilateral triangle of sides 20 are similar, as the angles are the same, but are not congruent, as the length of the sides is different) and this happens because we only have information of the angles and know nothing of the sides.

How does the graph show that the rate of change is constant?
A graph has a constant rate of change when the graph is linear and portrays a straight line. The slope will remain constant which forms the straight line in the graph.
Answer:
Because it is a straight line
Step-by-step explanation:
If it changed there would be curves, points, corners, zig zags, since this is straight, that means the R.O.C commonly known as slope, is not changing

An employee at a factory is paid $9.25 per hour plus an $8.00 bonus for every 20 transformers assembled. Last week an employee worked 36 hours and assembled 380 transformers. How much money did the factory employee actually earn per hour last week rounded to the nearest cent?
Answer: -$13.47 per hour
Step-by-step explanation:
Hi, to answer this question we have to write an expression:
The total amount earned by the employee will be equal to the product of the number of hours he worked (36) and the amount paid per hour (9.25) ; plus the product of the amount paid for every 20 transformers assembled (8) and the number of transformers assembled (380)divided by 20 :
9.25 (36) + 8 (380/20) =
Solving:
333+ 8 (19) =
333+152 = $485
If we divide the result by the number of hours:
485 /36 = $13.47 per hour
Feel free to ask for more if needed or if you did not understand something.

$13.47 per hour

x =
What’s the answer?
Answer:
12
Step-by-step explanation:
use Pythagorean theorem
37^2 = 35^2 + x^2
x= ±[tex]\sqrt[2]{37^2-35^2}[/tex]
x1 = 12
x2= -12 but it is illogical as length cannot be negative
answer: x = 12
Answer: x = 12
Step-by-step explanation:
a^2 + b^2 = c^2
35^2 + b^2 = 37^2
b^2 = 1369 - 1225
b = √144 = 12

The circumference of a wheel is 0.46π, and we simply have to multiply that by 829 which is 381.34π or 1197.41.
Answer:
see below
Step-by-step explanation:
Find the circumference
C = 2 * pi *r
C = 2(.23) * pi
C = .46pi
Since the wheel rotated 829 times, multiply the circumference by 829
829 * .46 pi
381.34 pi
If pi = 3.14
1197.4076 meters
If using the pi button
1198.01494 meters

What is the value of h?
The graph shows the function f(x) = (2.5) was horizontally
translated left by a value of h to get the function g(x) = (2.5)
-2.
0
2
5
Answer:
Option (1). h = -2
Step-by-step explanation:
This question is incomplete: here is the complete question.
The graph shows the function f(x) = [tex](2.5)^{x}[/tex] was horizontally shifted by a value of h to get the function g(x) = [tex](2.5)^{x-h}[/tex]. What is the value of h ?
From the graph attached,
Point (0, 1) lies on function f(x).
If the graph of function f(x) is shifted h units left horizontally, rule for the translation will be,
f(x + h) → g(x)
For 2 units shift to the left horizontally,
f(x + 2) → g(x)
[tex](2.5)^{x+2}[/tex] = [tex](2.5)^{x-h}[/tex]
By comparing both the sides,
x + 2 = x - h
h = -2
Therefore, Option (1) will be the answer.
