All of them involve y intercepts

f(x) means y
g(x) means  y

y intercept is where the graph crosses the y axis or when x=0 so set x=0

f(x)
x=0 when y=-7.5
y int=-7.5


g(x)
x=0
set x=0
y=3^0-7
y=1-7
y=-6


f(x) yint=-7.5
g(x) yint=-6


A. y int of f(x) is less than yint of g(x)
-7.5<-6
true

B. this is oposite of A so this is wrong

C. this says that g(x) has no yint, false

D. they yints are eqla
-7.5=-6
false




answer is A

A rectangular lawn, 100 feet long by 50 feet wide, is to have two sidewalks installed that will cut the lawn in half both ways,
Damm [24]

Answer:

3.41 feet

Step-by-step explanation:

Area = Length × Breath

Area of the rectangular lawn = 100 × 50

                                                = 5000 feet²

The sidewalk must occupy an area no more than 10% of the total lawn area.

So, the area of the sidewalk would be not more than  = 10% × 5000

                                                                                         = 0.10 × 5000

                                                                                        = 500 feet²

Let the width of the sidewalk = x feet

area of the side walk = (L×W of the long way) + ((L-x)×W of the short way)

(100 × x) + ((50 - x) × x) < 500

100x + (50-x)(x) < 500

-x²  + 150x < 500

-x² + 150x = 500

-x² + 150x - 500 = 0

By using quadratic formula

x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}

x=\frac{(-150)\pm\sqrt{(150)^2-4(-1)(-500)} }{2(-1)}

x=\frac{-150\pm \sqrt{20500} }{-2}

x=75-5\sqrt{205} or x=75+5\sqrt{205}

x = 3.41089 ≈ 3.41 feet  or  x = 146.58

Therefore, width of the sidewalk would be 3.41 feet.

A battalion of 520 soldiers goes through 16,380 pounds of rations in 3 weeks. If 780 more soldiers join the battalion, how many
Scorpion4ik [409]

They would need 34.125 tons of rations.


In order to find this, we first need to see how many pounds of rations a single soldier eats in a week. To do this, we take the total eaten in 3 weeks and divide by 3. Then we divide by the number of soldiers.


16,380/3 weeks= 5460 lbs per week


5460/520 soldiers = 10.5 lbs per soldier per week


Now we look to see how many soldiers we will have in total after adding. There are 520 to start and we add 780 to get 1300 total. Next we multiply that by the total per soldier per week.


10.5lbs per soldier per week * 1300 soldiers = 13,650lbs per week


Then we have to multiply by the 5 weeks that battalion will be there.


13,650lbs * 5 weeks = 68,250lbs of rations or 24.125 tons.

The center of a circle is at (-5 12) and it has a radius of 16. what is the equation of the circle?
Naya [18.7K]

Answer:

(x+5)^2+(y-12)^2=256

Step-by-step explanation:

Comparing the given (x+5)^2+(y-12)^2=256

to                                   (x - h)^2 + (y - k)^2 = r^2,  

we see that h must be -5, k must be 12 and r must be 16.  This is the desired equation of the circle with center at (-5, 12) and radius 16.
