An acute angle is an angle that is less than 90*. so, assuming that they are talking about a normal sheet of paper and a normal window, both are out.

Knives pointed end is right.
Scissors as wide as they can go will be an obtuse angle so no.
A sharpened tip of a pencil will be correct.

D and E. An acute angle is any angle that is less than 90(a right angle). A is an obtuse angle(more than 90). And B + C are right angles. Hope this helps you!

Graph the direct variation y=−1.5x. Using the graph, find the value of y corresponding to the value of x equal to 1; 0; 2; 3.

Y_Kistochka [10]

X=1
y=-1.5(1)
y=-1.5
(1,-1.5)

x=0
y=-1.5(0)
y=0
(0,0)

x=2
y=-1.5(2)
y=-3
(2,-3)

x=3
y=-1.5(3)
y=-4.5
(3,-4.5)

all you do is substitute the x value in the equation to get y

A rectangle has a height of 5m^4 and a width of m^2-2m-1.

In-s [12.5K]

Answer:

area of the rectangle = 5(m⁶ - 2m⁵ - m⁴) or 5m⁴(m² - 2m - 1)

Step-by-step explanation:

The rectangle has a height of 5m⁴ and the width is m² - 2m - 1.The area of the rectangle is the product of the width and the height.

width = m² - 2m - 1

height = 5m⁴

area of rectangle = 5m⁴ × (m² - 2m - 1)

area of rectangle = 5m⁴(m² - 2m - 1)

area of the rectangle = 5m⁶ - 10m⁵ - 5m⁴

area of the rectangle = 5(m⁶ - 2m⁵ - m⁴)

The area of the entire rectangle can be expressed as 5(m⁶ - 2m⁵ - m⁴) or 5m⁴(m² - 2m - 1)

Find the value of y.

olga nikolaevna [1]

Try this option:
1. the sides of the biggest triangle are 16; x and √(16²-x²); the sides of the smallest triange are x;5 and y. The smallest triangle ~ the biggest triangle. Using the property of the similar triangles:
$\frac{x}{5} = \frac{16}{x}, \ then \ x= \sqrt{80}$
2. according to the Pyphagorean theorem (in the smallest triangle):
$y= \sqrt{ \sqrt{80^2} -5^2} = \sqrt{55}$

answer: y=√55.
