Trey is making a small sign in the shape of a triangle for her store. He wants the height of the triangle to be 8 inches. The ar

ea of the sign must be less than 20 square inches. (Trey doesn't want to buy more material.) Write an inequality that describes the possible base lengths (in inches) of the triangle. Use b for the base length of the triangular sign.

Two best friends, Pluto and Goofy, have very different hobbies. Pluto likes to skydive from a height of 24,568 feet. Goofy likes
DIA [1.3K]

Answer:

They are 24, 692 feet aprart

Step-by-step explanation:

Let us assume at the instance we are measuring their position, that Pluto is at the highest point in the air, which is = 24,568 feet, and Goofy is at the lowest point of the sea (that he can go) = 124 feet.

Before we can proceed with the addition, we need to establish a datum, which will serve as the reference point from which the two distances are measured. This definitely is the sea level, because altitude and depth are usually measured above and below sea level.

Pluto's location to the sea level = 24,568 feet

Goofy's Location to the sea level = 124 feet

their distance apart = 24,568 feet + 124 feet =24, 692 feet apart

Solve the simultaneous equations. <br>Y=5x^2 + 4x-19<br>Y=4x+1 ​
Olegator [25]

Answer: x1=-2

x2=2

Step-by-step explanation:

5x²+4x-19=4x+1

5x²+4x-19-4x-1=0

5x²-20=0

5x²=20

x²=20/5

x²=4

x1=-√4=-2

x2=+√4=2

In circle E with m \angle DEF= 70m∠DEF=70 and DE=13DE=13 units find area of sector DEF. Round to the nearest hundredth.
Anuta_ua [19.1K]

Answer:

103.18units³

Step-by-step explanation:

Area of the sector DEF = theta/360 * πr²

r is the radius

theta is the angle subtended at the centre

theta =70 degrees

radius DE = 13units

Substitute

Area of the sector = 70/360 * 3.14(13)²

Area of the sector = 7/36 * 530.66

Area of the sector = 3,714.62/36

Area of the sector = 103.18units³ (to the nearest hundredth)

What is the equation of the line that is parallel to the line y = 1/3x + 4 and passes through the point (6, 5)?
Gnom [1K]
--------------------------------------------------
Find Slope
--------------------------------------------------
y = -1/3 x + 4                                      
Slope = -1/3                                       
Slope of the parallel line = -1/3          


--------------------------------------------------
Insert slope into y = mx + c
--------------------------------------------------
y = -1/3 x + c                                  

--------------------------------------------------
Find y-intercept
--------------------------------------------------
y = -1/3 x + c                                   
at point (6, 5)
5 = -1/3 (6) + c                                 
5 = - 2 + c                                         
c = 5 + 2                                         
c = 7

--------------------------------------------------
Insert y-intercept into y = -1/3x + c
--------------------------------------------------
y = -1/3 x + 7 

--------------------------------------------------
Answer: y = -1/3 x + 7 (Answer B)
