Answer:
C=hypotenuse [h]=50 feet
A=[base]=40foot.
B=perpendicular [p]=?
Area =?
we have
By using Pythagoras law
p²+b²=h²
B²=40²=50²
B²=50²-40²
B=√900
B=30feet
we have
Area of triangle =½×A×B=½×30×40=600feet²
<u>the roped off </u><u>area</u><u> </u><u>is</u><u> </u><u>6</u><u>0</u><u>0</u><u> </u><u>square</u><u> </u><u>feet</u><u>.</u>
<u>it</u><u> </u><u>is</u><u> </u><u>a</u><u> </u><u>right</u><u> </u><u>angled</u><u> </u><u>triangle</u><u>.</u>
Answer:
(2,-9)
Step-by-step explanation:
-2+4=2
-7-2=-9
down=negative
right=positive
left=negative
up=positive
3x²-8x+4=0
(3x-2) (x-2)=0
x=2/3 , x = 2
Hence, the polynomial has two positive roots.
Option A is the correct choice.
To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
First we have parentheses.
-4(3 - 1) + 2
3 - 1 = 2
-4(2) + 2
We have no exponents so go on to multiplication
-4(2) + 2
-4 * 2 = -8
-8 + 2
No division so go to addition
-8 + 2
When adding a positive number with a negative number you will act as if you are subtracting the two numbers, then take the sign of the largest number (disregarding the signs). In this case the largest number is 8 and its sign is negative. Your answer will have a negative sign.
-6
