Make n the subject of m= n² + 3
Andrej [43]

The n subject of m = n² + 3  is  n=\sqrt{m-3}

How is n made the subject of m = n² + 3 ?

m = n² + 3

n² = m- 3

n=\sqrt{m-3}

What does making n the subject mean?

  • To make n the subject of the formula or equation, we must rearrange the variables in the formula or equation to  have a single variable n that is equivalent to the other variables in the formula.
  • The equation is then rearranged such that each term containing n is placed on the same side of the equation.
  • If n appears in several words, factorization might be necessary.
  • Just one n needs to be displayed at the conclusion to make it the subject.
  • The result of square rooting a number or variable as an inverse operation may be positive or negative.

The lengths of the base and legs of an isosceles triangle are in the ratio of 3;2 the perimeter of triangles is 105 find the len
iVinArrow [24]
I guess you meam 3:2 instead of 3; 3
Anyhow,
The sides of isoceles triangle are leg, leg , base
each leg =2
while the base =4
To find the number you have to divide the ratio by total and multiply into 105
The base
3/7 × 105 = 45
The leg
2/7 × 105 = 30
Therefore, The length of the base = 45 cm

Enter the expression using exponents. 11 × 11 × 11 × 11 × 11 =
Alla [95]

Answer:

the answer should be 11^{5} or 11^5

Explanation:

Since there are five 11 in the equation, the answer should be 11^{5} or 11^5

You shouldn't write 161051 as the answer because it is NOT a exponent.

Please help me on this problem
Anna71 [15]

Answer:

The pairs of integer having two real solution forax^{2} -6x+c = 0 are

  1. a = -4, c = 5
  2. a = 1, c = 6
  3. a = 2, c = 3
  4. a = 3, c = 3

Step-by-step explanation:

Given

ax^{2} -6x+c = 0

Now we will solve the equation by putting all the 6 pairs so we get the  following

-3x^{2} -6x-5 = 0 for a = -3 , c=-5

-4x^{2} -6x+5 = 0 for a = -4 , c=5

1x^{2} -6x+6 = 0 for a = 1 , c=6

2x^{2} -6x+3 = 0 for a = 2 , c=3

3x^{2} -6x+3 = 0 for a = 3 , c=3

5x^{2} -6x+4 = 0 for a = 5 , c=4

The above  all are Quadratic equations inn general form ax^{2} +bx+c=0

where we have a,b and c constant values

So for a real Solution we must have

Disciminant , b^{2} -4\timesa\timesc \geq 0

for a = -3 , c=-5 we have

Discriminant =-24 which is less than 0 ∴ not a real solution.

for a = -4 , c=5 we have

Discriminant = 116 which is greater than 0 ∴ a real solution.

for a = 1 , c=6 we have

Discriminant =12 which is greater than 0 ∴ a real solution.

for a = 2 , c=3 we have

Discriminant =12 which is greater than 0 ∴ a real solution.

for a = 3 , c=3 we have

Discriminant =0 which is equal to 0 ∴ a real solution.

for a = 5 , c=4 we have

Discriminant =-44 which is less than 0 ∴ not a real solution.
