Write an equation of a line that passes through the point (0,-2) and is perpendicular to the image shown.
Elina [12.6K]

Answer:

Brainliest Answer would be appreciated. Option 1 is the best

Step-by-step explanation:

The slope of the line on the graph is -1/3. A perpendicular line's slope is always the negative reciprocal of it, so your slope of the perpendicular line would be 3.

Also, since you are passing through the point (0, -2), -2 would be your y-intercept, making your equation for the perpendicular line y = 3x - 2.

How do I get the Central angle?
melamori03 [73]

Answer:

199.8°

Step-by-step explanation:

The circle has radius r = 7 ft.

Now, the circumference of the circle is given by the formula C = 2πr

So, C = 2 \times \frac{22}{7} \times 7 = 44 ft.

Now, 44 ft arc length is equivalent to 360°  

Hence, 24.42 ft arc length is equivalent to \frac{360}{44} \times 24.42 = 199.8 degree.

Therefore, the central angle is 199.8° (Answer)

William picked 3 and 3/8 pints of blueberries Marcie picked 1 and 5/8 pints more than William picked How many pints blueberries
valentina_108 [34]
So, in this question you will add 3 3/8 and 1 5/8. So, first add 3 and 1 and you will get 4. Next, you will add 3 and 5 (this symbolizes 3/8 + 5/8) so you should get 8/8 which is equal to 1. So, 1 plus the 4 from the main number gives you 5. I believe the correct answer is 5.

What is the value of a if va- vh is equals to 1 <br><br>​
velikii [3]

Answer:

\displaystyle a = \frac{1+vh}{v}

Step-by-step explanation:

we want to figure out a value of a for the following condition

\displaystyle va - vh = 1

to do so factor out v;

\displaystyle v (a - h )= 1

divide both sides by v which yields:

\displaystyle  \frac{(a-h) \cancel{(v)}}{ \cancel{v}}=  \frac{1}{v}

therefore,

\displaystyle a-h =  { \frac{1}{v}}

now,add h to both sides:

\displaystyle a =  \frac{1}{v}+h

further simplification if necessary:

\displaystyle a =\boxed{   \frac{1+vh}{v}}
