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

Answers

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

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

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
