Archy [21]

Answer:

B) Exp. Decay

Step-by-step explanation:

Standard form of a point that goes through-2,4 and the slope is -1/7
lesantik [10]

<u>Answer:</u>

Standard form of a line passing through (-2, 4) and having slope of  -1/7 is x + 7y = 26

<u>Solution:</u>

Given that we need to determine standard form of a line that goes through (-2 , 4) and slope of the line is -1/7

Standard form of line passing through point ( a , b ) and having slope m is given by

(y – b) = m ( x – a)   --------(1)

In our case given point is ( -2 , 4 ) and slope is -1/7 that means

a = -2 , b = 4 , m = -(1/7)

On substituting given value of a , b and m is equation (1) we get

(y-4)=\left(-\frac{1}{7}\right)(x-(-2))

=>(y-4)=\left(-\frac{1}{7}\right)(x+2)

=> 7( y - 4 ) = -x – 2

=> 7y + x = -2 + 28

=> x + 7y = 26  

Hence standard form of a line passing through (-2,4) and having slope of –(1/7) is x + 7y = 26

How do you solve this?
masha68 [24]
Here's what i found online:

<span>a/3+4=6

We simplify the equation to the form, which is simple to understand
<span>a/3+4=6

Simplifying:
<span> + 0.333333333333a+4=6

We move all terms containing a to the left and all other terms to the right.
<span> + 0.333333333333a=+6-4

We simplify left and right side of the equation.
<span> + 0.333333333333a=+2

We divide both sides of the equation by 0.333333333333 to get a.
<span>a=6

Hope this helped :-)</span></span></span></span></span></span>

You work 4 hours on Monday, 4.5 hours on Tuesday, 7.25 hours on Thursday, and 12 hours on Saturday. If you get paid $11.52 per h
____ [38]

Answer:

$181.44

Step-by-step explanation:

First, you convert the hours worked to minutes <em>(h)×60=(min)</em>.

4 × 60 = 240     4.5 × 60 = 270        7.25 × 60 = 435

Then, you add the minutes worked together.

240 + 270 + 435 = 945

Then, convert the total minutes worked to ours.

945 ÷ 60 = 15.75

Finally, multiply 11.52 (the pay per hour) by 15.75 (the total hours worked)

$11.52 × 15.75h = $181.44

A right circular cylinder has a height of 20 1/2 ft and a diameter 1 1/5 times its height.
AfilCa [17]
  • Height=h=20-1/2=20.5ft
  • Diameter=1-1/5=1.2
  • Radius=1.2/2=0.6ft

\\ \sf\longmapsto V=\pi r^2h

\\ \sf\longmapsto V=3.14(0.6)^2(20.5)

\\ \sf\longmapsto V=3.14(0.36)(20.5)

\\ \sf\longmapsto V=23.17ft^3
