Which are solutions of the equation 4x2 – 7x = 3x + 24? Check all that apply. x = –4 x = –3 x = -3/2 x = 2/3 x = 2 x = 4
Ivahew [28]
4x2 - 7x = 3x + 24
 First we rewrite the quadratic equation:
 4x2 - 7x - 3x - 24 = 0
 4x2 - 10x - 24 = 0
 The solutions to the quadratic equation in this case are:
 x1 = 4
 x2 = -1.5
 Answer:
 x = -3/2
 x = 4

as viewed from Cliff 360 m above sea level the angle of depression of a ship is to 28° how far is the ship from the shore
andrezito [222]
The distance of the ship from the shore is given by:
tan θ=opposite/adjacent
θ=28°
adjacent=x
opposite=360 m

substituting the values in our equation we get:
tan 28=360/x
solving for x we get
x=360/tan 28
x=677.06 m

Which statements are true regarding the area of circles and sectors? Check all that apply.
AveGali [126]

Answer:

The correct options are a,b.

Step-by-step explanation:

The area of sector of a circle equals

Area of a sector = \theta r^{2}

where

\theta is the angle subtended at the center by the sector

r is the radius of circle

This indicates that area of the sector depends on:

1) Radius of circle

2) Angle  subtended at the center by the sector

3) Area of sector does not depend on pi.

Also if we know the area of the sector only  we cannot calculate area of area of whole triangle as we need one more information either angle of the sector and vice versa.
