Answer:

Initial value is \frac{1}{2}.

Step-by-step explanation:

Let us assume that the exponential function is f(x) = a(b)^{x} ...... (1)

Now, the point (0,\frac{1}{2}) will satisfy the above equation.

Now, this point on the graph of the exponential function will be sufficient to find the initial value of the function (1) i.e. a.

Now, putting the value x = 0 and y = \frac{1}{2} in the equation (1) we get, f(x) = a(b)^{x}

⇒ \frac{1}{2} = a(b)^{0} = a

⇒ a = \frac{1}{2} (Answer)

Anyone that can help me with this please?Not soo good at math.​

As it is right angled , we can use pythagoras theorem.

Using the therorem :

(x+2)² + (4x+4)² = (5x)²

x² + 4x + 4 + 16x² + 32x + 16 = 25x²

25x² - 17x² - 36x - 20 = 0

8x² - 36x - 20 = 0

2x² - 9x - 5 = 0

2x² -10x + x - 5 =0

2x(x-5) + 1(x-5) =0

(x-5)(2x+1) = 0

x = 5 or x = -1/2

x cannot be -1/2 as it would make hypotenuse negative.

So x = 5

Sides are 7 m, 24 m , 25 m

The area = 1/2 × base × height

Area = 1/2 × 24 × 7 = 84 m²

7x-8y=13 solve for y
Gala2k [10]
Get y alone
so
-8y=13-7x (by subtracting 7x from both sides)
now you still want y by itself so you divide by -8
leaving you with
y=-13/8 + 7/8
