Answer:
The y intercept is -1 and the slope is 4/1
Step-by-step explanation:
When you are trying to find the y-intercept, you look at where the line crosses over the y axis. In this case it was at -1.
The slope indicates how many units it is going up/down or left/right. In this case, the distance between each point is up 4, and right 1. so the slope would be 4/1.
I hope this helps :)
Answer:
50.41 feet
Step-by-step explanation:
Hypotenuse = length of ladder
31 = opposite side of angle
sin(angle) = (opposite)/(hypotenuse)
sin(78) = (36)/(hypotenuse)
hypotenuse = sin(78)/ (36)
hypotenuse = 50.41 feet
length of ladder = 50.41 feet
Answer:
<u>1</u><u> </u><u> </u><u> </u><u>x</u><u> </u><u> </u>( a + b ) × h
2
<u>1</u><u> </u>x ( 9× + 4 + 12× -2) x h
2
<u>1</u> x ( 13× + 10× ) × h 7x + 8= 15× a squared + b squared is equals to c squared
2 10 x + × = 15×
<u>1</u><u> </u>x ( 23x ) x h 100× + × = 225
2 x = 225 - 100
x = 125
x = 11.1803398875
x = 11.2
11.5 x h
11.5 x 11.2
= <u>128</u><u>.</u><u>8</u> height is 11.2
Step-by-step explanation:
Formula for trapezium half multiplied by the top and the bottom multipliedby height. As u constantly glance at the
question we dont know the height .adjacent plus opposite gives u hypotenuse .
