-4 would be the distance. I always look at a number line and count the distance

-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10

$\large\boxed{Answer:}$

We will use trigonometric identities to solve this. I will use θ (theta) for the angle.

First of all, we know that cotθ = 1/tanθ. This is a trigonometric identity.

We can replace cotθ in the expression with 1/tanθ.

$sin\theta tan\theta sec\theta \frac{1}{tan\theta}$

Simplify: 1/tanθ * tanθ = tanθ/tanθ = 1

So now, we have:

$sin\theta sec\theta$

Next, we also know that secθ = 1/cosθ. This is another trigonometric identity.

We can replace secθ with 1/cosθ in our expression.

$sin\theta \frac{1}{cos\theta}$

Simplify:

$\frac{sin\theta}{cos\theta}$

Our third trigonometric identity that we will use is tanθ = sinθ/cosθ.

We can replace sinθ/cosθ with tanθ.

Now we have as our final answer:

$\large\boxed{b.\ tan\theta}$

Hope this helps!

For the function

jeka57 [31]

Answer:

x = 1

Step-by-step explanation:

For a quadratic function $f(x)=ax^2+bx+c$ , the axis of symmetry is

$x=-\frac{b}{2a}$ .

This comes from using part of the Quadratic Formula for finding zeros of the function:

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a} = \frac{-b}{2a} \pm \frac{\sqrt{b^2-4ac}}{2a}$

See the -b/(2a) in the first term? That's the x-coordinate of the vertex (turning point) of the parabolic graph of the function. The axis of symmetry goes through the vertex.

Interest = $72.30 Principle = ? Rate = 5% Time = 3 years

gladu [14]

Answer:

Step-by-step explanation:

Answer:

P = $ 482.00

Equation:

P = I / rt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

P = 72.3 / ( 0.05 × 3 ) = 482

P = $ 482.00

The principal required to

accumulate interest of $ 72.30

on a rate of 5% per year for 3 years is $ 482.00.

hope it helps :)
