The given equation is:

$y= \sqrt{x+3}$

We need to find which set of parametric equations, result in the equation given above. The correct answer is option A.

$x=5t, y= \sqrt{5t+3}$

From first equation, we can write t =x/5. Using this value in second equation, we get:

$y= \sqrt{5( \frac{x}{5} )+3} \\ \\ 
y= \sqrt{x+3}$

Thus the set of equations in option A result in the given relation.
So, the answer to this question is option A

Let us say that:<span>
P = present value
F = future value
i = interest rate
n = period

P = F / [ (1 + i ) ^n ]
P = 200000 / [ (1 + 0.011) ^6 ]

The volumes of two cylindrical cans of the same shape vary directly as the cubes of their radii. If a can with a six-inch radius

Cerrena [4.2K]

Answer:

The second similar can with a radius of 24-inch radius will hold 12 gallons

Step-by-step explanation:

The given parameters are;

The volumes of the cylindrical can ∝ (The radius of the cans)³

The volume of first can, V₁ = 1¹/₂ pints

The radius of the first can, r₁ = 6-inch

The radius of the second can, r₂ = 24-inch

Therefore, we have;

V ∝ r³

V = k × r³

∴ 1¹/₂ pints ∝ (6 in.)³

1¹/₂ pints = 43.3125 in³

∴ 43.3125 in³ = k × 216 in.³

The constant of proportionality, k = 43.3125/216 = 0.2005208333

Therefore, we have for the second can, we have;

V₂ = k × r₂³ = 43.3125/216 × (24 in.)³ = 2772 in.³

The volume of the second can = 2772 in.³

1 in.³ = 0.004329 gallons

∴ 2772 in.³ = 2772 × 0.004329 gallons = 12 gallons

Therefore, the volume the second similar can with a 24-inch radius will hold = 12 gallons.

Which equation graphs as a vertical line with an undefined slope? A) y = 3x B) x = 2 3 C) y = 2 3 D) y = − 2 3 x + 1

kenny6666 [7]

Answer:

<h2>B) x = 2/3</h2>

Step-by-step explanation:

y = a - horizontal line (a - any real number) - slope = 0

x = a - vertical line (a - any real number) - undefined slope

y = mx + b - diagonal line (m - any real number except 0, b - any real number) - m - slope

You have to combine like terms (terms that have the same variable(x,y....) and power/exponent)²³

(4x³ - 4 + 7x) - (2x³ - x - 8) Distribute -1 into (2x³ - x - 8)

(4x³ - 4 + 7x) + (-)2x³ - (-)x - (-)8 (two negative signs cancel each other out and become positive)

(4x³ - 4 + 7x) - 2x³ + x + 8 Now combine like terms

4x³ - 2x³ + 7x + x - 4 + 8 (I rearranged for the like terms to be next to each other)

2x³ + 8x + 4 It is equivalent to B

$(-3x^2+x^4+x)+(2x^4-7+4x)$ Combine like terms

$-3x^2+x^4+2x^4+x+4x-7$ (I rearranged for the like terms to be next to each other)

$-3x^2+3x^4+5x-7$ It is equivalent to D

(x² - 2x)(2x + 3) Distribute x² into (2x + 3) and distribute -2x into (2x + 3)

(x²)2x + (x²)3 + (-2x)2x + (-2x)3

When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together

2x³ + 3x² - 4x² - 6x Combine like terms

2x³ - x² - 6x It is equivalent to A

[Info]

When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together. (You can combine the exponents only if they have the same variable)

For example:

$x^{2} (x^3)=x^{(2+3)}=x^5$

$(y^3)x^2=y^3x^2$ (You can't combine them because they have different exponents of y and x)

$(5^2)(5^4)=5^{(2+4)}=5^6=15,625$
