Step-by-step explanation:
Assume the parabola is vertical.
y = a(x-0)^2 +7
y = ax^2 + 17
Plug in (1,-2) and solve for a
-2 = a1^2 + 17
a = -19
y = -19x^2 + 7

Answer:
x=1
Explanation:
3x+4*2x=11
(We move all terms to the left)
3x+4*2x-(11)=0
( We multiply elements )
3x+8x-11=0
(We add all the numbers together, and all the variables )
11x-11=0
( We move all terms containing x to the left, all other terms to the right )
11x=11
x=11÷11
x=1

Answer:
x = 13
Step-by-step explanation:
I created a proportion from similar sides HB ≈ LY and NH ≈ RL
28/21 = (3x - 7)/(x + 11)
then cross-multiply to get
28(x + 11) = 21(3x - 7)
28x + 308 = 63x - 147
28x = 63x - 455
-35x = -455
x = 13

A factory robot recently examined some bulbs, of which 4 were flawed and 26 were not. Considering this data, how many flawed bulbs would the robot be expected to find in a batch of 15 bulbs?
Answers
Answer:
2
Step-by-step explanation:
Given that:
Flawed bulbs = 4
Not flawed = 26
Total examined = (flawed + not flawed)
Total examined = (4 + 26) = 30
P(flawed) = flawed / total
P(flawed) = 4 / 30 = 0.1333333
If 15 is examined :
Expected number of flawed bulbs :
(4/30) * 15 = 2
Peter works two part time jobs. He is paid $6 er hour at job a and $9 per hour at job b. Last wee eter worked a total of 24 hours at both jobs and madr $189. Hobmny hours dud peter work at job a?
Answers
Answer: Peter worked 9 hours at job a
Step-by-step explanation:
Step 1
Let the number of hours worked in job a = x
and number of hours worked in job b = y such that the total hours worked would be expressed as
x=y= 24 ---eqn 1
also since $6 and $9 dollar are paid per hour for the job and the total amount made is $189, it should be expressed as
6x + 9y =$189--- equation 2
Step 2
Now we have gotten two expressions to solve for number of hours, we can now solve
x+y= 24 ---eqn 1
6x + 9y =$189--- eqn 2
Using elimination method, we multiply equation 1 by 6 and subtract from equation 2
6x + 9y =189
-6x+6y=144
3y=45
y= 45/3 =15
To find x
x+y = 24
x+15=24
x= 24-15
x= 9
fff
Therefore Peter worked 9 hours at job a and 15 hours at job b
