x=[tex]\sqrt5/2[/tex] , x = -[tex]\sqrt5/2\\[/tex]

Step-by-step explanation:

2x^2-5=0

add 5 to both sides

2x^2-5+5=0+5

2x^2=5

(2x^2/2) = 5/2

x^2=5/2

x=[tex]\sqrt5/2\\[/tex] , x = -[tex]\sqrt5/2[/tex]

To determine the nature of the roots of the quadratic equation y [tex]= 2x^2 - 5[/tex], we can analyze its discriminant (denoted by Δ).

The discriminant is calculated using the formula Δ [tex]= b^2 - 4ac,[/tex] where a, b, and c represent the coefficients of the quadratic equation in the standard form [tex]ax^2 + bx + c = 0.[/tex] For the given equation, a [tex]= 2,[/tex] b [tex]= 0,[/tex]and c [tex]= -5.[/tex]Plugging these values into the discriminant formula, we have: Δ [tex]= 0^2 - 4(2)(-5) Δ = 0 + 40 Δ = 40[/tex]The discriminant is positive, indicating two distinct real roots.

Since the discriminant is greater than zero, we can conclude that the roots of the equation are real and different. Therefore, the nature of the roots for y[tex]= 2x^2 - 5 i[/tex]s that it has two distinct real roots.

Convert the fraction to a decimal, then multiply by  100  .

Answer:

Yes (A)

Step-by-step explanation:

The right angle (90 degree angle) at H makes it a right triangle

Answer:  Choice D

Step-by-step explanation:

p=2w+2l  Subtract 2w from both sides

p - 2w = 2w - 2w +2l   2w-2w = 0 cancels

p- 2w = 2l . Divide both sides by 2  2/2 =1 cancels leaving l isolated

p - 2w/2 = l

Reverse

l =  p-2w/2

9 multiplied by 3 equals 27

9 yards= 27 feet

Answer:

45

Step-by-step explanation:

Since

5 : 225 = 1 : X

Then we know

225/5 = X/1

Multiplying both sides by 1 cancels on the right

1 × (225/5) = (X/1) × 1

1 × (225/5) = X

Then solving for X

X = 1 × (225/5)

X = 45

Therefore

5 : 225 = 1 : 45

Answer:45

Step-by-step explanation:well all you do is divide 5 from 225

≈ 24 cm

Hi there !

c = 2πr  } => c = πd => d = c/π

Answer:

x = -4

Step-by-step explanation:

Subtract 17 on both sides to get 6x = -24 then divide 6 to both sides to get your answer of x = -4

First, you need to get 6x by itself. So you would subtract 17 from both sides. After that you should have 6x= -24.Then you need to get x by itself. You divide 6 from both sides. The answer is x= -4.

The first arrow goes from 0 to 3, which is 3 units.

The second arrow goes from 3 to 6, which is another 3 units.

The total units is 3 + 3 = 6

This means you have 2 different sets of 3, which can be modeled by 2 x 3.

The second choice is correct.

Answer:

Step-by-step explanation:

Solving the inequality

[tex]\frac{x+3}{6}[/tex] > [tex]\frac{x}{4}[/tex] + 1

Multiply through by 12 ( the LCM of 6 and 4 ) to clear the fractions

2(x + 3) > 3x + 12

2x + 6 > 3x + 12 ( subtract 2x from both sides )

6 > x + 12 ( subtract 12 from both sides )

- 6 > x , that is

x < - 6

The only value less than - 6 is - 10

Thus x = - 10 is a solution to the inequality

Answer:

2.07

Step-by-step explanation:

The reason for that is if the thousandths place was greater that 5 it will change the 7 to an 8

so when rounding the number will change if it is greater than 5

if  less than it will stay the same and the rest will become 000 after it

Answer: B,C,D,F

Step-by-step explanation:

All the correct mathematical statements that represent the quantities and constraints in the given situation are;

Option B; 5 ≤ n ≤ 8

Option C; c = 2n

Option D; l = c

Option F; 10 ≤ l ≤ 16

We are told that;

n = the number of people

c = the number of cups

l = the number of scoops of lemonade powder.

        the least amount of lemonade = 5 × 2 = 10

        the maximum lemonade = 8 × 2 = 16

        This can be written in inequality form as;

         10 ≤ l ≤ 16

The only options that correspond with all the inequalities gotten above are; Options B, C, D, F.
