Answer:

8.2cm

Step-by-step explanation:

Using SOH CAH TOA

cos theta = adjacent/hyp

cos 47 = h/12

h = 12cos47

h = 12(0.6819)

h = 8.18

Hence the height h to 1 dp is 8.2cm

If you shift the absolute value parent function, F(x) = |x|, left 4 units, what is the equation of the new function?
san4es73 [151]

Answer:

The equation of new function is: G(x)=|x+4|

Step-by-step explanation:

We are given:

If you shift the absolute value parent function, F(x) = |x|, left 4 units,

We need to find:

the equation of the new function

We know that: If we have parent function f(x) and g(x)=f(x+c) there will be horizontal translation left c units.

We are parent function, F(x) = |x|

So, Our function went translation of 4 units left

So, the new function will be:

G(x)=|x+4|

So, The equation of new function is: G(x)=|x+4|

Solve system of equation by elimination<br> 4x+3y=-1<br> 5x+4y=1
zvonat [6]

Answer:

<u>x= -7 , y= 9</u>

Steps:

4x+3y=-1

5x+4y=1

First, multiply the top equations by -5, and the bottom by 4 to get :

-20x-15y=5

20x+16y=4

Then, you’re going to add the two equations with them being on top of each other so you can easily see what cancels out :

-20x-15y=5

+ 20x+16y=4

———————

0+1y=9

From this, you get :

y=9

Now that you have one variable, find x by substituting 9 for y in one of the equations, I choose :

4x+3y=-1

So :

4x+3(9)=-1

Then simplify by multiplying 3 and 9 :

4x+27=-1

Then subtract 27 on each side :

4x=-28

Then, divide by 4 to get that :

x= -7

Hope this helps!!
