Answer:

y = 4(2)^{x}

Step-by-step explanation:

An exponential function in standard form is

y = ab^{x}

Substitute points from the graph into the equation to find a and b

Using (0, 4 ), then

4 = ab^{0} [ b^{0} = 1 ], so

a = 4

y = 4b^{x}

Using (1, 8 ), then

8 = 4b^{1} = 4b ( divide both sides by 4 )

b = 2

y = 4 (2)^{x} ← exponential equation

kiruha [24]

Answer:

25%

Step-by-step explanation:

let the Market Price of the Watch (M.P.) be x

CP for Rahim=x-[(20/100)*x]

CP = (1 *x) /5 = 4x/5

SP for Rahim = MP = x

Difference (Profit) = SP-CP = x - (4x/5) = (5x - 4x)/5 = x/5

Profit % = (Profit/CP) * 100

Profit % = (x/5)/(4x/5) * 100

Profit % = 25 %

The function f(x) is defined as follows:
Leno4ka [110]

Answer:

f(-3)=-8\\f(2)=4

Step-by-step explanation:

In order to find the values of a piecewise function, we first have to determine which piece we are using.

For f(-3), x=-3. This means that we need to use 3x+1 as -3\leq 0

f(-3)=3(-3)+1\\\\f(-3)=-9+1\\\\f(-3)=-8

For f(2), x=2. This means that we need to use f(x)=4 as x is equal to 2.

f(x)=4

Find the area of the trapezoid
Alexandra [31]

Answer:

\sf area \  of \ trapezoid \ =375 \ mm^2

Explanation:

\sf area \  of \ trapezoid \ = \dfrac{1}{2} * ( base \  1 + base \ 2 ) * height

using the formula:

\sf area \  of \ trapezoid \ = \dfrac{1}{2} * ( 14+ 36 ) * 15

\sf area \  of \ trapezoid \ = \dfrac{1}{2} * ( 50 ) * 15

\sf area \  of \ trapezoid \ =25 * 15

\sf area \  of \ trapezoid \ =375 \ mm^2

nevsk [136]

Answer:

Step-by-step explanation:

If I remember how to solve these questions correctly, if there is a triangle that is 45 degrees, the hypotenuse will be times the square root of 2 of the other two sides (which are equal to eachother). Hope this helped!
