The area of the circle based on the radius given is 102.1 inches ²

<h3>How to calculate the area?</h3>

It should be noted that the area of a circle is calculated thus:

= πr²

where r = radius

π = 3.142

Therefore, when the the radius of a circle is 5.7 inches. This will be calculated for the area thus:

= πr²

= 3.142 × 5.7²

= 3.142 × 32.49

= 102.1 inches ²

Slope = (-2 + 4)/(-2-2) = 2/-4 = -1/2

y = mx + b
so
b = y - mx
b = -2 -(-1/2)(-2)
b = -2 - 1
b = - 3

equation
y = -1/2x - 3

answer is B.
y = -1/2x - 3

line passes through the point (-3,-4) and its y-intercept is (o, -9). What is the equation of the line that is parallel to the f

12345 [234]

Answer:

$y=-\frac{5}{3}x-2$

Step-by-step explanation:

The first line has a slope of -5/3 found using the points in the slope formula.

$m=\frac{y_2-y_1}{x_2-x_1} =\frac{-9--4}{0--3}=\frac{-9+4}{0+3}=\frac{-5}{3}$

Parallel lines have the same slope. So -5/3 is the slope of the second line. Write its equation using the point slope form $y-y_1=m(x-x_1)$ .

$y--7=-\frac{5}{3}(x-3)\\y+7 = -\frac{5}{3}(x-3)\\y=-\frac{5}{3}x + 5 -7\\y=-\frac{5}{3}x-2$

Calculate the pay for the following day of a weekly time card given a wage of $14.50/hr. Name Week of: SI Morning lo Out Monday

Vanyuwa [196]

As we can see in the card, on Monday the worker clocked in at 08:15 and clocked out at 12:15. This means they worked 4 hours.

They then clocked in at 13:00 and clocked out at 17:30. This means they worked for 4 and a half hours.

Since they earn a wage of $14.50/h, they earned:

$(4+4.5)\cdot14.50=8.5\cdot14.50=123.25.$

So that day they earned $123.25
