Answer:

5 + 6

Step-by-step explanation:

1: Simplify 5 + 3x, which is 5 + 6

2: He was wrong. he got 16 when the answer is 11. He could have just added 5 to 6 and gotten the right answer, while from the looks of it he used multiplication and had some bad math.

When placed near a second charge, a 60-μC charge experiences a force of 0.30 N. What is the electric field strength at the locat
jeka57 [31]

Answer:

E=5000N/C

Step-by-step explanation:

From the question we are told that

Charge q= 60 \mu C

Force F_=0.30N

Generally the equation for electric field strength is mathematically given as

E=F/q

E=\frac{0.30}{60*10^-^6}

Therefore

E=5000N/C

How to find where the equations meet.
zzz [600]
The first sentence → x - 2y = -1
the second one → 3x - 2y = -3

multiply the first one by -1
you can get → -x + 2y = 1

plus two sentences together
you can get → 2x = -2

so you are able to know that x = -1
and y = 0

The standard form of the equation for a quadratic function is, with he vertex of the graph of the function at the point (p,q). t
ludmilkaskok [199]

Answer:

p = ½ (x₁ + x₂)

q = a (x₁x₂ − ¼ (x₁ + x₂)²)

Step-by-step explanation:

y = a (x − x₁) (x − x₂)

Expand:

y = a (x² − x₁x − x₂x + x₁x₂)

y = a (x² − (x₁ + x₂)x + x₁x₂)

Distribute a to the first two terms:

y = a (x² − (x₁ + x₂)x) + ax₁x₂

Complete the square:

y = a (x² − (x₁ + x₂)x + ¼(x₁ + x₂)²) + ax₁x₂ − ¼ a(x₁ + x₂)²

y = a (x − ½ (x₁ + x₂))² + a (x₁x₂ − ¼ (x₁ + x₂)²)

Therefore:

p = ½ (x₁ + x₂)

q = a (x₁x₂ − ¼ (x₁ + x₂)²)
