Answer:

seven-eighths of a number minus three

Step-by-step explanation:

the algebraic expression given to us is:

\frac{7}{8} y-3

we have seven-eighths multiplied by a number "y" (this can also be expressed as seven-eighths  of the number) and then, to that we substract 3 (minus three).

With this information we can conclude that the phrase that best describes this expression is:

seven-eighths of a number minus three

which is the first option.

y-ysub1=m(x-xsub1)

m=slope=(-2-3)/(2-(-1))=-5/3

ysub1 is 3 and xsub1 is -1

The cartesian coordinates of a point are given. find polar coordinares of the point where r<0 and
Ad libitum [116K]

Find the polar coordinates in the usual way, then negate r and add 180° to θ.


You know that

... r = √(x² + y²)

... θ = arctan(y/x) . . . . . taking quadrant into account


The coordinates (r, θ) and (-r, θ+180°) specify the same point.

Neporo4naja [7]

Answer:

176.625 sq.ft, 4.8 sq.ft

Step-by-step explanation:

Area of circle=πr^2 or πd^2/4
11. Given,
d=15 ft
Now,
Area=πd^2/4
3.14*15^2/4
176.625 ft^2
Therefore, the area approximation is 176.6 sq.ft
12.
Given,
d=3.5 ft
Now,
Area= πd^2/8
3.14*3.5^2/8
4.8 sq.ft
I got the answer by dividing the area of circle by 2 as semicircle is half of circle.
