Answer:
y = -4x + 64.
Step-by-step explanation:
The slope is rise / run = (64-0) / (0-16)
= 64 / -16
= -4.
The y-intercept is y = 64 so the equation is
y = -4x + 64.
Answer:
xˆ2+10x+9
Step-by-step explanation:
first, multiply x by x and by 1, that would be (xˆ2 and x), then multiply 9 by x and 1, that would be( 9x and 9), add the two parenthesis, and it totals out to xˆ2+10x+9
Answer:
1) b=14.34 units.
2) a=20.48 units
Step-by-step explanation:
since, the triangle is a right angled triangle so we can use the trignometric identity in order to find the values of a and b.
let the base be denoted by 'B'.
height or perpendicular side of the triangle be denoted by 'P'.
and hypotenuse of the triangle be denoted by 'H'.
then using sine and cosine trignometric identity we have:
![\sin x=\dfrac{P}{H}](https://tex.z-dn.net/?f=%5Csin%20x%3D%5Cdfrac%7BP%7D%7BH%7D)
and ![\cos x=\dfrac{B}{H}](https://tex.z-dn.net/?f=%5Ccos%20x%3D%5Cdfrac%7BB%7D%7BH%7D)
Here x=35°
and H=25 units , P=b and B=a
Hence ![\sin 35=\dfrac{b}{25}](https://tex.z-dn.net/?f=%5Csin%2035%3D%5Cdfrac%7Bb%7D%7B25%7D)
as ![\sin 35=0.573576](https://tex.z-dn.net/?f=%5Csin%2035%3D0.573576)
hence, b=14.3394 units.
also ![\cos35=\dfrac{a}{25}](https://tex.z-dn.net/?f=%5Ccos35%3D%5Cdfrac%7Ba%7D%7B25%7D)
and ![\cos35=0.819152](https://tex.z-dn.net/?f=%5Ccos35%3D0.819152)
Hence a=20.4788 units
In two decimal places we could represent it as:
a=20.48 units
and b=14.34 units.
