The slope intercept form of (-4, 8) and (9, 8)

Mathematics

Black_prince [1.1K]3 years ago

3 0

Step 1: Find the slope

(y-y)/(x-x) = (8-8)/(9+4) = 0

Step 2: Substitute into the slope intercept equation

y - y = m(x - x)

y - 8 = 0(x - 9)

If the problem just wants plain, slope intercept form, then this is your answer.

If not, y = 8

Answer:

49.5 mi

Step-by-step explanation:

Area of a triangle is A = (height) X (base) / 2

So if you plug in the numbers you get:

806.9 = (32.6) X (base) / 2

1613.8 = (32.6) X (base)

1613.8 / 32.6 = base

base = 49.5 mi

Forces of 9 lbs and 13 lbs act at a 38º angle to each other. Find the magnitude of the resultant force and the angle that the re

fiasKO [112]

Answer: $R=20.84\ lb\quad 22.57^{\circ},15.43^{\circ}$

Step-by-step explanation:

Given

Two forces of 9 and 13 lbs acts $38^{\circ}$ angle to each other

The resultant of the two forces is given by

$\Rightarrow R=\sqrt{a^2+b^2+2ab\cos \theta}$

Insert the values

$\Rightarrow R=\sqrt{9^2+13^2+2(9)(13)\cos 38^{\circ}}\\\Rightarrow R=\sqrt{81+169+184.394}\\\Rightarrow R=\sqrt{434.394}\\\Rightarrow R=20.84\ lb$

Resultant makes an angle of

$\Rightarrow \alpha=\tan^{-1}\left( \dfrac{b\sin \theta}{a+b\cos \theta}\right)\\\\\text{Considering 9 lb force along the x-axis}\\\\\Rightarrow \alpha =\tan^{-1}\left( \dfrac{13\sin 38^{\circ}}{9+13\cos 38^{\circ}}\right)\\\\\Rightarrow \alpha =\tan^{-1}(\dfrac{8}{19.244})\\\\\Rightarrow \alpha=22.57^{\circ}$

So, the resultant makes an angle of $22.57^{\circ}$ with 9 lb force

Angle made with 13 lb force is $38^{\circ}-22.57^{\circ}=15.43^{\circ}$

Using the integer tiles interactive, what steps do you need to do to evaluate the following expression? Select two options. –5(–

dangina [55]

The steps you need to do to evaluate the expression are (b) Drag zero pairs to the window. and (c) Remove the 5 groups of –2 tiles.

<h3>How to determine the steps you need to do to evaluate the expression</h3>

The expression is given as:

-5(-2)

The above expression represents the product of -5 and -2

This can be interpreted as:

Removal of 5 groups of -2; to remove means negative
Dragging zero pairs of 5 and 2 to the interactive window

Hence, the steps you need to do to evaluate the expression are (b) Drag zero pairs to the window. and (c) Remove the 5 groups of –2 tiles.
