It's an acute isosceles triangle. Because all the angles are acute (acute) and only two sides are equal (isosceles) :) hope this helps :)

How to find an equation for a line through two given points?

xz_007 [3.2K]

Answer:

The equation of the line is: $y = 0.6x + 0.6$

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept.

Two points:

We have these following two points in this exercise:

x = -6, y = -3, so (-6,-3)

x = 4, y = 3, so (4,3)

Finding the slope:

Given two points, the slope is given by the change in y divided by the change in x.

Change in y: 3 - (-3) = 3 + 3 = 6

Change in x: 4 - (-6) = 4 + 6 = 10

$m = \frac{6}{10} = 0.6$

Then

$y = 0.6x + b$

Finding b:

We replace one of the points in the equation to find b. I will use (4,3).

$y = 0.6x + b$

$3 = 0.6*4 + b$

$2.4 + b = 3$

$b = 0.6$

The equation of the line is: $y = 0.6x + 0.6$

Determine the standard form of the equation for the circle with center (h,k) =( -5, 1/2) and radius r=1

FrozenT [24]

Answer:

$(x + 5) ^{2} + {(y - \frac{1}{2}) }^{2} = 1$

Step-by-step explanation:

the formula of a circle is

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

knowing the values of h, k, and r we can substitute them into the formula

Cos9x - cos5x = -2sin2x.sin7x
sin17x - sin3x = 2sin7x.cos10x
so f(x) = $\frac{-2sin2x.sin7x}{2sin7x.cos10x}$ = $\frac{-sin2x}{cos10x}$
