y =  {4}^{x}  - 2 \\ for \: y \: intercept \: x \: s \\ is \: 0 \\ y =  {4}^{0} - 2 \\ y = 1 - 2 \\ y =  - 1 \\

Y intercept : (0,-1)

Hope it helps

Answer: Hope this helps you.

-2

Step-by-step explanation:

y = mx+b (B is y-int)

y = 4^x-2

-2 is clearly replacing the b (y-int) meaning b, the y-int, is -2

Solve the equation for x
KengaRu [80]
You can do this 2 ways, one is knowing the special right triangles called triplets. An example of a triplet would be 3-4-5 where the largest value is the hypotenuse. In this example, the other 2 sides are 3 and 4 and the missing side is the hypotenuse, so using the knowledge of triplets, we can find that the hypotenuse is 5.

algebraically, we can use the Pythagorean theorem; a^2+b^2=c^2 where a and b are the opposite and adjacent and where c is the hypotenuse. We can then substitute in the values to get : 3^2 + 4^2 = c^2. When simplified, we get 9+16=c^2. Simplify further, and get 25=c^2. Now we Square root both sides to solve for C. Finally, we get C=5. Your missing side is 5.

The equation y = 0.002x - 0.30 can be used to determine the approximate cost, y in dollars, of producing x items. How many items
ArbitrLikvidat [17]

Answer:

193650

Step-by-step explanation:

Since the cost must be no more than 387$, you can substitute that number instead of y to get 387 = 0.002x - 0.30. you can add 0.30 to both sides to get 387.3 = 0.002x

Then you can divide both sides by 0.002 to get 387.3/0.002 = 193650

Help plz i have only tonight 11;59
Darina [25.2K]

Answer:

Base = 16, height 64

Step-by-step explanation:

It's a triangle so u have to multiply it with 1/2 or divide by 2, x will equal both height and base:

(1/2)4x^2 = 512

Multiply 2 to both sides

4x^2 = 1024

divide both sides by 4

x^2 = 256

\sqrt{x^2} = \sqrt{256}

x = 16, base is 16 and height is 16(4) = 64

Alright this took me some time but I got it now, u might think why 16 and 64? 16 times 64 is not 512, but the equation for a triangles area is \frac{b h}{2} or b·h·1/2 , so if u plug the numbers into the equation it will equal 512:

16 · 64 · 1/2= 1024 · 1/2 = 512
