As you can see in this picture we have a point on y- axis which is our y-intercept and f(x) 
so first we should find what WAS the y-intercept before adding k 
so we can say:
f(x) = 2(0) - 3 = -3 
so it WAS -3 .... but in this picture is -7 
so you have: 
-3 + k = -7 
k = -7 + 3 = -4 
so k is equal to -4 :)))
i hope this is helpful
have a nice day

andrey2020 [161]
Since Flying Falcon cost($8) is cheaper than Flying Bat($12), then the minimum possible cost each day would be the maximum possible Flying Falcon produced.
The maximum flying falcon produces is 60/day. Then, the amount of flying bat produced would be:

total= falcon + bat
70= 60+bat
bat= 70-60= 10

The minimum possible cost: falcon * falcon_cost + bat * bat_cost = 60*$8 + 10*$12 = $480+$120= $600

Simplified product ?
mel-nik [20]

Answer:

Last choice is correct.

Step-by-step explanation:

\left(\sqrt{10x^4}-x\sqrt{5x^2}\right)\left(2\sqrt{15x^4}+\sqrt{3x^3}\right)

\left(x^2\sqrt{10}-x\cdot x\sqrt{5}\right)\left(2\cdot x^2\sqrt{15}+x\sqrt{3x}\right)

\left(x^2\sqrt{10}-x^2\sqrt{5}\right)\left(2x^2\sqrt{15}+x\sqrt{3x}\right)

x^2\sqrt{10}\left(2x^2\sqrt{15}+x\sqrt{3x}\right)-x^2\sqrt{5}\left(2x^2\sqrt{15}+x\sqrt{3x}\right)

2x^4\sqrt{150}+x^3\sqrt{30x}-2\sqrt{75}x^4-x^3\sqrt{15x}

2x^4\cdot5\sqrt{6}+x^3\sqrt{30x}-2\cdot5\sqrt{3}x^4-x^3\sqrt{15x}

10x^4\sqrt{6}+x^3\sqrt{30x}-10\sqrt{3}x^4-x^3\sqrt{15x}

10x^4\sqrt{6}+x^3\sqrt{30x}-10x^4\sqrt{3}-x^3\sqrt{15x}

Hence final answer is 10x^4\sqrt{6}+x^3\sqrt{30x}-10x^4\sqrt{3}-x^3\sqrt{15x}

Luis, using appropriate safety precautions, fires a .22 caliber gun directly into the sky above him. The bullet travels at a spe
Tanya [424]

The equation represents height as a function of time.

The bullet was in the air for 75 seconds.

The equation is given as:

h(t) = -16t^2  + 1200t

The time spent in the air is the time it takes the bullet to land on the ground.

When the bullet is on the ground, the height is:

h(t) = 0

So, we have:

h(t) = -16t^2  + 1200t

-16t^2 + 1200t = 0

Factor out t

t(-16t + 1200) = 0

Split

t = 0 or -16t + 1200 = 0

t = 0 represents when the shot is fired.

So, we solve for t in -16t + 1200 = 0

Collect like terms

16t = 1200

Divide both sides by 16

t = 75

Hence, the bullet was in the air for 75 seconds
