First we do, 1/2*x=13÷1/2. Which gives us x=13 1/2. 13 1/2=26. Therefore, x=26. Hoped I helped. :)

1/2 x 13 = 6.5 in decimal form
Fractions Form: 1 1/2

1/1 + 1/2

((1 × 2) + (1 × 1)) / (1 × 2)

(2 + 1) / 2

3/2

= 3/2

= 1 1/2

IgorLugansk [536]

Answer:

The horizontal distance between the parking lot and the launch site is 470 meters

Step-by-step explanation:

Let

x-----> the horizontal distance between the parking lot and the launch site

we know that

The tangent of angle of 12 degrees is equal to divide the altitude of 100 meters by the horizontal distance

tan(12°)=100/x

Solve for x

x=100/tan(12°)=470 meters

Find the coordinates of the reflected image.

Goryan [66]

Answer:

The actual answer is A or 1 as you have it.

Step-by-step explanation:

All you have to do is just map out the coordinates yourself. You're looking for a reflection that goes across the Y axis, but NOT across the X axis.

Hope this helps you and anyone looking for an answer to their headache.

How to integrate with steps: (4x2-6)/(x+5)(x-2)(3x-1)

joja [24]

$\displaystyle\int\frac{4x^2-6}{(x+5)(x-2)(3x-1)}\,\mathrm dx$

You have a rational expression whose numerator's degree is smaller than the denominator's. This tells you you should consider a partial fraction decomposition. We want to rewrite the integrand in the form

$\dfrac{4x^2-6}{(x+5)(x-2)(3x-1)}=\dfrac a{x+5}+\dfrac b{x-2}+\dfrac c{3x-1}$

$\implies4x^2-6=a(x-2)(3x-1)+b(x+5)(3x-1)+c(x+5)(x-2)$

You can use the "cover-up" method here to easily solve for $a,b,c$ . It involves fixing a value of $x$ to make 2 of the 3 terms on the right side disappear and leaving a simple algebraic equation to solve for the remaining one.
