True

$\frac{1 \: yard}{3 \: feet} = \frac{x \: yard}{13 \: feet}$

3x = 13

$x = \frac{13}{3} yards$

Write the first four terms of the sequence:<br> a = 2<br> an = a(n-1) + 4

eduard

We have sequence equation $a_n=a(n-1)+4$ .

In this case n is a natural number (1, 2, 3, ...).

So start inserting and computing value of $a_n$ given that you know the value of n and a.

$a_1=2(1-1)+4=4$ (first term)

$a_2=2(2-1)+4=6 \\a_3=2(3-1)+4=8 \\a_4=2(4-1)+4=10$

Hope this helps.

n chemistry, the pH of a solution is defined by: pH space equals space minus log space left square bracket straight H plus right

slavikrds [6]

Answer:

The correct option is;

pH = 4.1

Step-by-step explanation:

The given information are;

The hydrogen ion [H⁺] concentration in tomato juice = $10 ^{-4.1}$

The pH of a solution = -㏒{H⁺] = -㏒( $10 ^{-4.1}$ ) = -(-4.1) × ㏒(10) = 4.1

The pH of the of the tomato juice = 4.1

The pH is the term used to refer to the acidity of water with the range of pH values ranging from 0 to 14 where pH values of a solution lesser than 7 are considered acidic while pH values above 7 indicate a basic solution.

Determine whether or not F is a conservative vector field. If it is, find a function f such that F = ∇f. (If the vector field is

gavmur [86]

$\nabla f=(ye^x+\sin y)\,\vec\imath+(e^x+x\cos y)\,\vec\jmath$

then

$\dfrac{\partial f}{\partial x}=ye^x+\sin y\implies f(x,y)=ye^x+x\sin y+g(y)$

Differentiating with respec to $y$ gives

$\dfrac{\partial f}{\partial y}=e^x+x\cos y=e^x+x\cos y+g'(y)$

$\implies g'(y)=0\implies g(y)=C$

So $F$ is indeed conservative, and

$f(x,y)=ye^x+x\sin y+C$

Simplify the expression a^b: 5x^4 y^2 * 3x^6 y^9

tatyana61 [14]

Answer:

3x(3x + 2)

Step-by-step explanation:

(4x2 - 2x) - (-5x2 - 8x)

= 4x2 - 2x + 5x2 + 8x.

= 4x2 + 5x2 - 2x + 8x.

= 9x2 + 6x.

= 3x(3x + 2).

I hope it is right.
