Answer:

Y intercept is 275. X intercept is 125.

Step-by-step explanation:

The y intercept is where the line meets the y axis. The x intercept is where the line meets the x axis. You just have to look at those.

From a point A that is 8.20 m above level ground, the angle of elevation of the top of a building s 31 deg 20 min and the angle

Mariulka [41]

Answer:

30.11 meters ( approx )

Step-by-step explanation:

Let x be the distance of a point P ( lies on the building ) from the top of the building such that AP is perpendicular to the building and y be the distance of the building from point A, ( shown in the below diagram )

Given,

Point A is 8.20 m above level ground,

So, the height of the building = ( x + 8.20 ) meters,

Now, 1 degree = 60 minutes,

⇒ $1\text{ minute } =\frac{1}{60}\text{ degree }$

$20\text{ minutes }=\frac{20}{60}=\frac{1}{3}\text{ degree}$

$50\text{ minutes }=\frac{50}{60}=\frac{5}{6}\text{ degree}$

By the below diagram,

$tan ( 12^{\circ} 50') = \frac{8.20}{y}$

$tan(12+\frac{5}{6})^{\circ}=\frac{8.20}{y}$

$tan (\frac{77}{6})^{\circ}=\frac{8.20}{y}$

$\implies y=\frac{8.20}{tan (\frac{77}{6})^{\circ}}$

Now, again by the below diagram,

$tan (31^{\circ}20')=\frac{x}{y}$

$tan(31+\frac{1}{3})=\frac{x}{y}$

$\implies x=y\times tan(\frac{94}{3})=\frac{8.20}{tan (\frac{77}{6})^{\circ}}\times tan(\frac{94}{3})^{\circ}=21.9142943216\approx 21.91$

Hence, the height of the building = x + 8.20 = 30.11 meters (approx)

3^2x5^2x2x5^35^5 please help

const2013 [10]

Answer:

2×3^2×5^10

Step-by-step explanation:

We presume you want the simplified product ...

3^2×5^2×2×5^3×5^5

The applicable rule of exponents is ...

(a^b)(a^c) = a^(b+c)

The bases are 2, 3, 5. The exponent of 2 is 1; the exponent of 3 is 2; the exponents of 5 are 2, 3, 5, so those get added.

= 2×3^2×5^(2+3+5)

= 2×3^2×5^10

What is (x+3)(2x-4) in the form of ax²+bx+c?

fenix001 [56]

FOIL

first = x*2x = 2x^2

outer = x*-4 = -4x

inner = 3 * 2x = 6x

last = 3 * (-4) = -12

add together

2x^2 -4x+6x-12

2x^2 +2x-12
