explanation: any number with a negative sign which is ( - ) is smaller than 0

and a number without a sign next to it is positive

a number line can show you both negative and positive to draw it

for example

__________________

-5 -4 -3 -2 -1 0 1 2 3 4 5

you can see we start from the left with the negative numbers

if you add a positive and a negative sign  to get the answer is the biggest number ik negative is always the smallest listen look at it like there is no signs and you see which one is the biggest then take that one

ex.

4+(-5)= -1

Question 1<br> Find the area of the shaded region.<br> 18 ft<br> 15 ft<br> 8 ft<br> A = ft?
qwelly [4]

Answer:

<h2>135 ft²</h2><h2 />

Step-by-step explanation:

see attached image

<u>shaded area = total area (1)  - unshaded triangular area (2)</u>

1.  area of a trapezoid = (a + b) * h/2

   where a = 8,  b = 18,  h = 15

   Area of trapezoid = (8 + 18) * 15/2 = 195 ft²

2.  Area of unshaded triangle = 1/2 (8) 15 = 60 ft²

shaded area =  195 - 60 = 135 ft²

If a certain canon is fired from a height of 8.9 m above the ground, at a certain angle, the height of the Campbell above the gr
qwelly [4]

Answer:

T=5.9235 seconds

Step-by-step explanation:

H(T)= -4.9T^2+27.52T+8.9.

The time it takes for the cannonball to strike the ground is the point at which H(T)=0

H(T)= -4.9T^2+27.52T+8.9.=0

-4.9T^2+27.52T+8.9=0

This is a quadratic equation and since we have a bunch of decimals we use the quadratic formula:

x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}

a=-4,9, b=27.52, c=8.9

T=\dfrac{-27.52\pm\sqrt{(-27.52)^2-(4*-4.9*8.9)} }{2*-4.9}\\=\dfrac{-27.52\pm\sqrt{757.3504-(-174.44)} }{-9.8}\\=\dfrac{-27.52\pm\sqrt{931.7904} }{-9.8}\\=\dfrac{-27.52\pm30.53 }{-9.8}\\T=-0.3071 \:or\:  5.9235\\T=5.9235 seconds

It takes 5.9235 seconds for the cannonball to strike the ground.

C.) -15,-10,-5,+20
The answer is C because it says rank them from lowest to highest the negatives will always be the lowest. When it’s a negative number and the number infront of the negative is higher than the rest is how yk that it’s the lowest .
