Line perpendicular to y=2/3+3 and passes through 2,1

Mathematics

Vlad [161]3 years ago

I'm assuming there is an x after 2/3?

y = (2/3)x + 3


First we invert the gradient to make it perpendicular.

y = (-3/2)x + 3


Now we need to make y equal to 1, when x is 2. Currently, y is 0, since (-3/2) * 2 is -3, plus 3 is 0. We could just add 4 instead of 3 to make y equal to 1, so the line...

y = (-3/2)x + 4

is perpendicular to the line you provided, and passes through (2, 1).

Answer:

1). a = 9.42 m

2). b = 6.37 m

3). c = 4.48 m

Step-by-step explanation:

In the figure attached,

By applying tangent rule in triangle ADE,

tan47 = \frac{h}{c}

c = \frac{h}{\text{tan}47}

c = \frac{4.8}{\text{tan}47}

c = 4.476

c ≈ 4.48 m

Now we apply the same rule in triangle ACE,

tan37° = \frac{h}{b}

b = \frac{h}{\text{tan}37}

b = \frac{4.8}{1.0724}

b = 6.37 m

Now apply the tangent in triangle ABE,

tan27° = \frac{h}{a}

a = \frac{h}{\text{tan}27}

a = \frac{4.8}{0.5095}

a = 9.42 m

Which properties were used to solve the following problem?
Stels [109]

Step-by-step explanation:

25(2x) + 25(3y)

25 · (2 · x) + 25 · (3 · y)

(25 · 2) · x + (25 · 3) · y                <em>Associative property </em><em>(a · b) · c = a · (b · c)</em>

(25 · 2)x + (25 · 3)y

(2 · 25)x + (3 · 25)y             <em>Commutative property</em><em> a · b = b · a</em>

<em>50x + 75y</em>

Circle A has an area of 452.16 ft^2 with a radius of 12 ft. If circle B has a radius of 17 ft, what is its area?
Dmitry [639]
To find this answer, you would need to use the equation for area of a circle, or in this case, a=3.14x289, since 3.14 is pi and 289 is your radius squared. giving you a final answer of 907.46 feet squared.
