Sauron [17]

Answer:

(B) $4\sqrt{37}$

Step-by-step explanation:

First, we determine the height of the triangle which we label as y.

Using Pythagoras Theorem.

$25^2=7^2+y^2\\y^2=25^2-7^2\\y^2=576\\y=\sqrt{576}\\y=24$

In the smaller right triangle with hypotenuse, x

Base = 7-3 =4 Units

Height, y= 24 Units

Therefore, applying Pythagoras Theorem.:

$x^2=24^2+4^2\\x^2=592\\x=\sqrt{592}\\ x=4\sqrt{37}$

Find the slope of the line: x/-1 + y/6 = 1

pychu [463]

The slope-intercept form: y = mx + b

m-the slope

$\dfrac{x}{-1}+\dfrac{y}{6}=1\\\\-x+\dfrac{y}{6}=1\ \ \ \ |add\ x\ to\ both\ sides\\\\\dfrac{y}{6}=x+1\ \ \ \ |multiply\ both\ sides\ by\ 6\\\\y=6x+6\\\\\\Answer:\boxed{The\ slope\ m=6}$

Trigonometry question! find y. round to the nearest tenth!

tresset_1 [31]

Answer:

Step-by-step explanation:

Look at the picture.

Use sine:

$sine=\dfrac{opposite}{hypotenuse}$

We have a measure of the angle and length of the hypotenuse:

$\alpha=29^o,\ hypotenuse=500\ ft$

$\sin29^o\approx0.48481$

Substitute:

$\dfrac{y}{500}=0.48481$ <em>multiply both sides by 500</em>

$y=242.405\to y\approx242.4$

Can i get help please

Olin [163]

Answer:

120x^3

Step-by-step explanation:

exponent rule --> a^b x a^c = a^b+^c

10^-6 x 10^7 = 10^6 + ^7

add / subtract numbers -- > -6 + 7 = 1

=2XX x 6X x 10

aponent rule --> a^b x a^c = a^b+^c

xxx = x^1 + ^1 + ^1

= 2 x 6x^1 + ^1 + ^1 x 10

= 2 x 6x^3 x 10

= 120x^3
