what will I get for the answer 12(2x2−8)+13(6x2−3)
Answers
Answer:
102x^2 - 135
Step-by-step explanation:
Here we must follow order of operations rules:
1. Anything enclosed inside parentheses must be done first
2. Multiplication before addition/subtraction
Thus, 12(2x^2−8)+13(6x^2−3) becomes (after multiplication):
24x^2 - 96 + 78x^2 - 39
The next step is to combine like terms:
102x^2 - 135
This cannot be simplified further. 102 and 135 have no common factors.
Thus, 12(2x^2−8)+13(6x^2−3) = 102x^2 - 135

Colin is painting figurines. He spends 20 minutes painting each figurine. After painting for 60 minutes, he still has 9 more figurines left to paint. The number fff of figurines left to paint is a function of ttt, the amount of time in minutes Colin spends painting.
Answers
Answer:
[tex]f(t) =-\frac{1}{20} t + 12[/tex]
Step-by-step explanation:
Given
[tex]t \to time[/tex]
[tex]f \to figurines[/tex]
Required
Determine the function
From the question, we have:
[tex]60\ minutes \to 9\ left[/tex]
This is represented as:
[tex]f(60) = 9[/tex] or [tex](60,9)[/tex]
If he spends 20 minutes on 1 figurine;
[tex]20\ minutes = 1\ figurine[/tex]
Multiply both sides by 3
[tex]60\ minutes = 3\ figurines[/tex]
This means that, he spends 60 minutes on 3
plus he still has 9 left
So, the initial figurines is:
[tex]f(0) =3 + 9[/tex]
[tex]f(0) =12[/tex] or [tex](0,12)[/tex]
So, we have:
[tex](60,9)[/tex] and [tex](0,12)[/tex]
Calculate the slope (m)
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{12- 9}{0 -60}[/tex]
[tex]m = \frac{3}{ -60}[/tex]
[tex]m = -\frac{1}{20}[/tex]
The equation is then calculated as;
[tex]f(t) = m * t + c[/tex]
[tex]f(t) = -\frac{1}{20} * t + c[/tex]
[tex]f(t) = -\frac{1}{20}t + c[/tex]
To solve for c, we have:
[tex]f(60) = 9[/tex]
So, we have:
[tex]9 = -\frac{1}{20} * 60 + c[/tex]
[tex]9 = -3 + c[/tex]
Add 3 toboth sides
[tex]c =12[/tex]
Hence, the equation is:
[tex]f(t) =-\frac{1}{20} t + c[/tex]
[tex]f(t) =-\frac{1}{20} t + 12[/tex]

f=-1/20t+12

Answers
Answer:
Mean value of score = 40.167 (Approx.)
Step-by-step explanation:
Given:
Number of students in class = 12
Numbers;
45 , 22, 12, 96, 63, 63, 78 , 12 , 69, 81, 3, 19
Find:
Mean value of score
Computation:
Mean = Sum of all observation / Number of students
Mean value of score = [45 + 22 + 12 + 96 + 63 + 63 + 78 + 12 + 69 + 81 + 3 + 19] / 12
Mean value of score = [482] / 12
Mean value of score = 40.167 (Approx.)

40 / 8 = 5

= 4× (√6²+8²)
= 4× (√100)
= 4×10
= 40
Q) 4 × (√(12/2)²+(16/2)² )

→ 4 × 10
→ 40 is the perimeter of rhombus.
A javelin thrower is running at 7mph and throws her javelin at 18mph at an angle of 13o with the horizontal. Determine the resultant speed and direction of the javelin. i need the magnitude and the direction !!! HELP WILL MARK BRALIEST
Answers
Magnitude: 24.93 mph
Direction: 9.37°
A javelin thrower throws her javelin at an angle of 13o
cos13°=v1/18
v1=cos13° * 18= 17.54mph
v=v1+7
17.54+7=24.54 mph
sin13°=v2/18
v2=sin13° * 18= 4.05mph
tan ∅ =v2/v=0.165
∅ =9.37°
cos ∅ =v/v3
v3=24.54/cos 9.37=24.93
What is the formula for resultant speed?
Multiply the acceleration by the time the object is being accelerated. For example, if an object falls for 3 seconds, multiply 3 by 9.8 meters per second squared, which is the acceleration from gravity. The resultant velocity in this case is 29.4 meters per second.
How do you find the resultant direction?join the tail of the first vector with the second vector's head and put the arrowhead. To determine the magnitude, measure the length of the resultant R, and find out the direction.
