Answer:

1. 0=-2x^{2} +x+3

Step by step explanation:

We are asked to find which of the given equation has our given coefficient values.

Since we know that in quadratic equations a is quadratic coefficient, b is linear coefficient and c is our constant term.

Let us see our given equations one by one.

1. 0=-2x^{2} +x+3

We can see that coefficient of quadratic equation in our given option are:

a (quadratic coefficient)=-2

b (linear coefficient)= 1

c (constant) =3

Therefore, 1st option is correct choice.

2. 0=2x^{2} +x+3

We can see that coefficient of quadratic equation in our given option are:

a (quadratic coefficient)=2

b (linear coefficient)= 1

c (constant) =3

Therefore, 2nd option is incorrect.

3. 0=-2x^{2} +3

We can see that coefficient of quadratic equation in our given option are:

a (quadratic coefficient)=-2

b (linear coefficient)= 0

c (constant) =3

Therefore, 3rd option in incorrect as well.

4.  0=2x^{2} -x+3

We can see that coefficient of quadratic equation in our given option are:

a (quadratic coefficient)=2

b (linear coefficient)= -1

c (constant) =3

Therefore, 4th option is incorrect too.

The Johnsons want to cover their backyard with new grass. Their backyard is rectangular, with a length of 3x – 5 feet and a widt
kolezko [41]

Answer:

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = length × width

Their backyard is rectangular, with a length of 3x – 5 feet and a width of 4x – 10 feet. This means that the area of the backyard is

(3x - 5)(4x - 10)

= 12x² - 30x - 20x + 15

= (12x² - 50x + 15) square feet

Their rectangular swimming pool, along with its surrounding patio, has dimensions of x + 8 by x – 2 feet. This means that the area occupied by the swimming pool and its surrounding patio is

(x + 8)(x - 2)

= x² - 2x + 8x - 16

= x² + 6x - 16

Assuming the swimming pool and its surrounding patio will not be covered with new grass, then the area of the region of the yard that they want to cover with new grass is

12x² - 50x + 15 - (x² + 6x - 16)

= 12x² - 50x + 15 - x² - 6x + 16

= 12x² - x² - 50x - 6x + 15 + 16

= 11x² - 56x + 31 square feet

<u>Answer:</u>

Vt = 4071.5 ft^3

<u>Step-by-step explanation:</u>

Givens:

  • R = 12
  • R = 2r => r = 6

Equations

  1. V = (4/3)(pi)r^3

Find: Vt (Total Volume)

Vt = (1/2)V1 + (1/2)(V2)

Vt = (1/2)(V1 + V2)                 <em>[Factor out (4/3) and (pi) from volumes]</em>

Vt = (1/2)(4/3)(pi)(R^3 + r^3)  <em>[Sub in Values]</em>

Vt = 4071.5 ft^3

Jack spent $40 on new shoes then he spent half of what he had left on clothes finally he gave five dollars to his brother now he
aleksandrvk [35]
This is a working backwards problem.  You know he has $35 at the end.  Before he gave his brother $5, he would have $40, which is half of what he had before he bought the clothes, so he would have had $80.  Before he spent the $40 on shoes, he would have had $120, so the answer is $120.

Please help im really confused :(​
pantera1 [17]

Answer:

a) π

b) 33.4

Step-by-step explanation:

C = πd

1) substitute 105 for C: 105 = πd

2) plug in approximate value of 3.14 for π: 105 = (3.14) d

3) isolate to solve for d: 105/3.14 = d

4) simplify: 105/3.14 ≈ 33.4
