I assume that you mean the *numeral* 7, the written for of the number in a common font.
This has no symmetry. In an extreme case, with the top extended to be the same length as the slant stroke, and restricting both to simple line segments, *then* you would have symmetry across a line bisecting the angle.

3# Find the missing variable (s). Round to the nearest tenth.

rewona [7]

Answer:

Step-by-step explanation:

This triangle is already positioned to match trig functions (also known as circular functions).

Point A is origin, side AC (length x) is on X axis,

side CB (length y) is parallel to Y axis.

***** You just remember *****

cos is horizontal, on X axis,

sin is vertical, on Y axis.

To get from unit triangle with hypotenuse 1,

horizontal side cos(θ), vertical side sin(θ), you multiply all sides by same number, namely, the specified length of the hypotenuse.

***** that's all you need to know *****

Draw a unit circle centered at A, mark point Y at intersection of circle and AB, and drop a vertical line from Y crossing X axis at X.

Then radial segment AY is 1, AB is 10

horizontal segment AX is cos(32°), AC is 10AX

vertical segment XY is sin(32°), CB is 10XY.

So x = 10 cos(32°), y= 10 sin(32°).

What is the x- intercept of y+ 12 =3 (x-9)?

Natalija [7]

Answer:

13,0

Step-by-step explanation:

12=3(x-9)

divide both sides by three

4=x-9

add 9 to both sides

x=13

so, the x intercept is (13,0)

Si mi hermano gana 589 pesos diarios si ha trabajado 15 días de este mes ¿cuánto dinero ha ganado?

weeeeeb [17]

Mi hermano ha ganado un dinero devengado de 8835 pesos en 15 días.

En esta pregunta debemos determinar el dinero devengado por un período de 15 días a partir de una tasa diaria constante. Esa cantidad es igual al producto de la tasa diaria constante, en pesos por día, y el número de días trabajados, en días:

$x = 589\,\frac{\$}{dia}\times 15\,dias$

$x = 8835\,\$$

Mi hermano ha ganado un dinero devengado de 8835 pesos en 15 días.

I need to know which points go wj ere please

g100num [7]

The equations give you information as to where to plot points.

For y = -x + 1, you know the slope is -1, and the line intersects the y-axis at (0, 1). The y-axis is the vertical line; to plot (0, 1), find 1 on the vertical line and mark it. Now, the slope is -1; that means the line will slope downwards. To plot more points, count 1 unit down from (0, 1) and 1 unit to the right. You should end up at (1, 0).Connect those and you have a line.

For y = -2x + 4, the slope is -2 (so it will also slope downwards), and the y-intercept is 4. Find (0, 4) and plot it. The -2 tells you to count 2 units down (instead of 1 like we did for the last equation) and 1 over. That is the second line.

I hope this helps.
