A sail is in the form of a right triangle that is three times as high as it is wide. The snail is made from 6 square meters of m

lara31 [8.8K]

Answer:

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

Suppose the base of right triangle sail is b

Suppose the height of right triangle sail is h

It is given that, it is three times higher as it is wide.

$h=3b$

Area of right triangle is A = $\frac{1}{2}*b*h$

$6=\frac{1}{2}*b*h$

Plugging the value of h in terms of b

$6=\frac{1}{2}*b*(3b)$

$b^2=4$

$b=2$

Hence height h = $3*2 = 6$

Hecne the height of sail is 6 meters. : Answer

Hope it will help :)

The equation Y-5<br> 5(x-4) is written in point-slope form. What is the y-intercept of the equation?

nirvana33 [79]

Answer:

The y-intercept is -15.

Step-by-step explanation:

y - 5 = 5(x - 4) is our equation in point-slope form.

point slope form is = y - y1 = m( x - x1)

So, we know that the slope is 5 and one point is (4, 5)

We can use this point and the slope to find the y -intercept.

y = mx + b is slope intercept form.

Let's input the values we know to find the y-intercept.

5 = 5(4) + b

5 = 20 + b

-15 = b

The y-intercept is -15.

ASAAPPPPPP!!!!! Complete the tables of values

velikii [3]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

$a^{-m}$ ⇔ $\frac{1}{a^{m} }$ and $a^{0}$ = 1

Substitute the values of x into $4^{-x}$

x = 0 → $4^{0}$ = 1 ⇒ a = 1

x = 2 → $4^{-2}$ = $\frac{1}{4^{2} }$ = $\frac{1}{16}$ , hence

b = $\frac{1}{16}$

x = 4 → $4^{-4}$ = $\frac{1}{4^{4} }$ = $\frac{1}{256}$ , hence

c = $\frac{1}{256}$
