Answer:

1 second

Step-by-step explanation:

s=-5\\u=0\\v=\\a=-10\\t=t

\begin{aligned}\textsf{Using} \quad s & =ut+\dfrac12at^2\\ \implies -5 & =(0)t+\dfrac12(-10)t^2\\ -5 & = -5t^2\\ t^2& = 1\\ t & = \pm\sqrt{1}\\ t & = 1\: \sf s\end{aligned}

4. The cube root parent function is vertically stretched by a factor of 3, reflected in the x-axis,
Mademuasel [1]

Using translation concepts, it is found that the equation that represents the new function is:

  • y = -3\sqrt[3]{x} - 8

The cube root parent function is given by:

y = \sqrt[3]{x}

<h3>Translation:</h3>

The function goes through these following translations:

  • Vertically stretched by a factor of 3, that is, it is multiplied by 3, hence y = 3\sqrt[3]{x}.
  • Reflected over the x-axis, that is, it is multiplied by -1, hence y = -3\sqrt[3]{x}.
  • Translated 8 units down, that is, 8 is subtracted from the function, hence y = -3\sqrt[3]{x} - 8.

Then, the equation is:

  • y = -3\sqrt[3]{x} - 8

Re-write the equation without the h component.
levacccp [35]

Answer:

f(x) = 2[\frac{3^x}{9}] + 2

f(x) = 8(4)^x

Step-by-step explanation:

Given

f(x) = 2(3)^{x-2} + 2

f(x) = \frac{1}{2}(4)^{x+2}

Required

Remove the h component

In a function, the h component is highlighted as:

f(x) = a^{x+h}

So, we have:

f(x) = 2(3)^{x-2} + 2

Split the exponents using the following law of indices:

a^m/a^n = a^{m-n}

f(x) = 2*\frac{3^x}{3^2} + 2

f(x) = 2*\frac{3^x}{9} + 2

f(x) = 2[\frac{3^x}{9}] + 2

<em>The h component has been removed</em>

f(x) = \frac{1}{2}(4)^{x+2}

Split the exponent using the following law of indices

a^{m+n} =a^m * a^n

So, we have:

f(x) = \frac{1}{2}(4)^x * 4^2

Express 4^2 as 16

f(x) = \frac{1}{2}(4)^x * 16

Divide 16 by 2

f(x) = 8(4)^x

Solve the system of equations using the substitution method. 2x+8y=4 x=−3y+5
goldenfox [79]
Since x=-3y+5, substitute x for -3y+5. 

2(-3y+5)+8y=4

Distribute. 

-6y+10+8y= 4

2y+10= 4

Subtract 10 on both sides. 

2y=-6

Divide by 2.

y=-3

Plug in y=-3. 

x=-3(-3)+5
x= 9+5
x=14

(14,-3)

We can check this. 

2(14)+8(-3)=4
28-24=4
4=4 <== this works

I hope this helps!
