Step-by-step explanation:

Answer:

x = - [tex]\frac{3}{2}[/tex] , x = 2

Step-by-step explanation:

To find h(g(x)) substitute x = g(x) into h(x) , that is

h(g(x))

= h(x + 1)

= (x + 1)²

= x² + 2x + 1

For h(g(x)) = 3x² + x - 5 , then

3x² + x - 5 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides

2x² - x - 6 = 0 ← in standard form

(2x + 3)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - [tex]\frac{3}{2}[/tex]

x - 2 = 0 ⇒ x = 2

Answer:

Step-by-step explanation:

0.8 cubic feet is closest to the number of cubic feet of water needed to fill the fish tank.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

To find the number of cubic feet of water needed to fill the fish tank

we need to first convert the dimensions of the tank from inches to feet.

since the conversion factor between cubic inches and cubic feet is 1,728.

Length in feet = 20 inches ÷ 12 inches/foot

= 1.67 feet

Height in feet = 12 inches ÷ 12 inches/foot

= 1 foot

Width in feet = 6 inches ÷ 12 inches/foot

= 0.5 feet

The volume of the fish tank in cubic feet is:

Volume = length × height × width = 1.67 feet × 1 foot × 0.5 feet = 0.835 cubic feet

Hence,  the number of cubic feet of water needed to fill the fish tank is 0.8 cubic feet, Option A is correct.

Answer:

0 real roots

Step-by-step explanation:

Given a quadratic equation in standard form

ax² + bx + c = 0 ( a ≠ 0 )

Then the discriminant is

Δ = b² - 4ac

• If b² - 4ac > 0 then 2 real and distinct roots

• If b² - 4ac = 0 then 2 real and equal roots

• If b² - 4ac < 0 then the roots are not real

- 9x² + x - 7 = 0 ← is in standard form

with a = - 9, b = 1, c = - 7 , then

b² - 4ac = 1² - (4 × - 9 × - 7) = 1 - 252 = - 251

Since b² - 4ac < 0 then the equation has no real roots

Answer:

The average distance between Earth and Pluto is same as average distance of Pluto from the Sun. This is 0.000628 light years, nearly.

Explanation:

The average distance obetween two planets is nearly the average distance of the outer planet from the Sun. Earth is inner to Pluto. Average Sun-Pluto distance = 5906.4 million km. Divide by 149597870 to get distance in Au. Further divide by 62900 to get distance in ly.

Answer:

Each dimension increased by 3 ft.

Step-by-step explanation:

Area of the original rectangle = 4 * 6 = 24 square feet

Increased dimension = x ft

New length = 6 + x

New width = 4 +x

New area = (6 + x)(4 +x)    {Use FOIL method}

                = 6*4 + 6*x + x*4 + x*x

                = 24 + 6x + 4x + x²

                = x² + 10x + 24

New area = 24 + 39

x² + 10x + 24 = 63

x² +10x + 24 - 63 = 0

x² + 10x  - 39 = 0

x² + 13x - 3x  - 3*13 = 0

x (x + 13) - 3(x + 13) = 0

(x + 13)(x -3) = 0   {Ignore x + 13, as it gives negative value}

x - 3 = 0

x = 3

Answer:

C.) Justin should have multiplie 3.8 and 7.9 first.

Step-by-step explanation:

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

1) 6x - 4 = -4 + 6x

6x -6x = -4+4

0 = 0

ans - true

2) 4x -6 = 4x + 3

4x-4x = 3+6

0 = 9

Ans - false

3) -2x+4=-3x+4

-2x + 3x = 4 - 4

x = 0

ans - false

Answer:

x = 18.0

Step-by-step explanation:

You must memorize the definitions of the trig functions and then these types of problems are easy.
